Owners of the 2021 SUBARU Ascent report engine/powertrain issues more than most other systems. Complaints concentrated in one area often signal a systemic weakness worth a targeted pre-purchase inspection.
Owners of the 2021 SUBARU Ascent report electrical issues more than most other systems. Complaints concentrated in one area often signal a systemic weakness worth a targeted pre-purchase inspection.
Owners of the 2021 SUBARU Ascent report visibility issues more than most other systems. Complaints concentrated in one area often signal a systemic weakness worth a targeted pre-purchase inspection.
Water pump failure causes rapid overheating. If the engine overheats even once, head gasket damage is likely — turning a $400 part into a $3,000+ repair.
Degraded transmission fluid destroys clutch packs and solenoids. CVT transmissions are especially sensitive — neglected fluid can result in a $4,000–$8,000 replacement.
On 4WD/AWD vehicles, neglected differential or transfer case fluid causes metal-on-metal wear. Replacement costs $1,500–$4,000.
Degraded coolant loses corrosion inhibitors and attacks aluminum engine components. Can cause head gasket failure and water pump corrosion.
Worn spark plugs cause misfires that can foul and crack catalytic converters. A $150 tune-up can prevent a $1,200 catalytic converter replacement.

My 2021 Subaru Ascent (40,000 miles) suffered multiple major mechanical failures that pose ongoing safety concerns: 1. Engine Oil Leak: The vehicle developed an active engine oil leak at 20,000 miles, posing a risk of fluid contacting hot exhaust/engine components under the hood or causing low oil levels during operation. Repair time more than 35 days due to parts not available. 2. Loose Factory Engine Mounts: At 25,000 miles, excessive engine shifting, vibration when braking, the dealer discovered loose engine mounts. 3. Transmission Valve Body Failure: At 40,000 miles The transmission Valve Body Failure and need replacement.
The contact owns a 2021 Subaru Ascent. The contact stated that while driving at an undisclosed speed, the vehicle started to stall, and the transmission failed to properly operate. The vehicle was pulled over to a nearby shop and was advised to take the vehicle back to the facility that performed the oil changes. Several days later, the contact's husband test drove the vehicle and was able to duplicate the failure. The vehicle was towed to a dealer to be diagnosed, and metal shavings were found in the oil. The dealer determined that the CVT transmission needed to be replaced. The vehicle was being repaired. The manufacturer was notified of the failure. The failure mileage was 101,541.
Oil leaking from upper and lower oil pan. Oil seeping from head gasket and CVT chain pump cover. RTV sealant failure. $4800 to repair. Subaru needs to solve these oil leak issues. Leaking oil is bad for the environment and engine failure could cause accidents and injury.
On May 14, 2026, while driving a 2021 Subaru Ascent (approx. 94,291 miles) on a Texas expressway at highway speed during rush hour, I experienced a sudden and significant loss of engine power. There were no warning lights, no safety system activation, and no advance indication of the failure. The vehicle decelerated abruptly with traffic behind it. Live OBD-II data was being logged during the drive and was provided to the service advisor at the authorized Subaru retailer. This incident occurred only 3 days and approximately 125 miles after the vehicle was returned following a major engine repair performed at an authorized Subaru retailer in Texas under active powertrain warranty. That repair was supervised by a Subaru of America District Quality Manager and Field Technical Specialist, who conducted a 110-mile validation drive prior to release. Prior to the highway failure, visible fluid leaks were documented across the intake ducting, residue on lower engine components, a sweet and burning odor after driving, and milky sludge returning to the coolant reservoir — all within 125 miles of pickup. These are consistent with ongoing oil and coolant cross-contamination, which was the original diagnosis documented in the dealership's digital service portal. The vehicle has now undergone three major engine teardowns since March 17, 2026 — over 100 days out of service — for the same underlying powertrain issue on the FA24 engine. The current repair involves cylinder heads sent to a third-party machine shop. Vehicle telematics confirm the vehicle has not been started since May 27, 2026. This report is filed to establish a federal safety record of the highway power loss incident and the recurring nature of this powertrain failure. An active Subaru of America customer advocacy case is on file regarding this vehicle.
I am submitting this complaint regarding a 2021 Subaru Ascent that I purchased new from Herb Gordon Subaru in Maryland. The incident occurred while driving on I-95 at approximately 75 mph with my family, including children, in the vehicle. The vehicle experienced a sudden and complete powertrain failure without any prior warning indicators. This created an immediate and serious safety risk on a busy highway. Fortunately, we were able to safely maneuver the vehicle out of traffic and avoid a collision. Prior to this incident, the vehicle had undergone regular maintenance, and there were no indications of any imminent powertrain failure. While a routine fluid service had been recommended, it was not presented as urgent and was planned to be completed at a later time. Following the incident, I conducted further research and learned that the vehicle had previously been subject to a manufacturer recall involving engine harness/ECM-related issues, which had been completed prior to the sale. This material information was not disclosed to me at the time of purchase and only came to my attention after the failure occurred. Had I been informed of this recall history at the time of purchase, it would have reasonably influenced my decision-making, and I would have reconsidered or sought further clarification before proceeding. The estimated repair cost is approximately $11,000. Subaru of America has offered $2,000 in goodwill assistance, which I consider inadequate given the severity of the failure and the associated safety concerns. This matter raises concerns regarding non-disclosure of material recall history at the time of sale, potential underlying defect, and possible breach of the implied warranty of merchantability. In addition this recall is not even recorded in the NHTSA website.
I had catastrophic transmission failure. The car was completely inoperable. Thankfully this only happened in a parking lot. If this were yo happen while merging into traffic it could have been very dangerous. This was the second cvt in this vehicle. The 1st transmission was replaced around 52kmiles. The second transmission lasted not even 13 months sndless than 15k miles. Subaru replaced the transmission for a 3rd time at a cost of 1k to me. I no longer have the car.
Issue 1: Complete transmission failure was diagnosed by Subaru dealer March 24, 2026 at 5 years and 6 months after purchase with an odometer reading of 45,000 miles (drive train warranty 5 yrs/60,000 miles). Had to purchase and have installed a rebuilt Subaru transmission. First noticed transmission was slipping with a large load in vehicle May 2025 at 4 years and 8 months after purchase at about 40,000 miles on odometer. The issue was subsequently not noticed under typical load until slipping transmission signs reappeared December 2025. Made appointment in March 2026 due to a planned trip to [XXX] mid-February to mid-March. Failed transmission poses critical safety risks including loss of acceleration, stalling in traffic and unexpected deceleration. Subaru of New England was able to install the transmission at about 50% of the initial estimate over 12,000 (final paid 5400). Subaru of America file was claimed (Case # XXX-XXX) for the balance, but any further reimbursement was rejected. Issue 2: Driver window alternating between getting stuck fully opened as well as reversing to the open position when trying to roll up. The failure of window regulator and channel run was diagnosed by Subaru dealer March 24, 2026 at 5 years and 6 months after purchase with an odometer reading of 45,000 miles. Had to purchase and replace the Subaru window regulator and channel run. Power window failures in the open position create significant safety risks including vehicle theft, interior damage from weather and occupant vulnerability.

I am a CPST. I use the Joie Mint Latch with my own child. On multiple occasions I have found on multiple occasions that when securing the lower rigid latch it will flip to green (secure) when it is not actually latched. It is during install when "jiggling" it into position. I am concerned parents who arent as well educated on car seats may not double check the latch before traveling and their child may not be safe.
2021 Subaru Ascent (VIN#***). Water found dripping down both second row seatbelts on multiple occasions during or following heavy rain, accumulated into mold growth on the carpet in front of second row seats to the front of the 3rd row seats (cargo area dry, front footwells dry). Authorized Subaru dealer technician report (dated 10/29/25 and 12/3/25 copy pasted into email) explicitly documents 'condensation build up on the interior of roof (seat belt area)' due to unlocated water intrusion. The dealer attributes this to 'leaf debris' in the front cowl area and rear hatch hinge despite the leak occurring at the rear C-pillar (and notably cargo area and front footwells showed no moisture making this physically impossible). Despite confirmed moisture exposure to critical passive restraint systems, the dealer relays that the manufacturer has issued a verbal-only warranty denial (stating no addl records exist aside from the initial technician report) and suggest the only repair be carpet replacement, with refusal of confirmation of the source of the leak and no proposal of replacing the 2nd-row seatbelt retractors nor provide a written safety guarantee. The vehicle is covered by an active 8yr/120,000-mile Subaru Gold Plus Added Security Plan (Agreement #*******, started on 8/2/21), yet the manufacturer is refusing to honor the contract for the defect or the resulting biohazard ('mold spouts' documented by their technicians on carpeting and into the foam). This unaddressed moisture creates an unreasonable risk of internal corrosion and failure of the seatbelt G-sensor/locking mechanisms on both sides. Also as an immunocompromised owner (due to medication for multiple sclerosis to such an extent that requires monthly IVIG infusions), the documented mold is a significant health hazard. Vehicle has only 15,166 miles. Correspondence with dealer and SoA as well as agreement# are available on request. Date of incident was when taken to dealership (events in summer/fall 2025)
While driving my Subaru Ascent, a check engine warning light appeared on the dashboard. Shortly afterward, I noticed smoke coming from the engine compartment. I immediately pulled over and turned the vehicle off. Within moments, flames began coming from under the hood. The fire spread rapidly, and within 5-10 minutes the entire vehicle was fully engulfed in flames. The fire originated from the engine compartment. The vehicle was a total loss. Subaru of America was notified on 12/23/2025, but no follow-up or update on investigation has been responded. The vehicle was always serviced with Subaru. This sudden, traumatizing and catastrophic failure with no prior warning.
The transmission on our 2021 Subaru Ascent is slipping and failing to accelerate, RPMs reving, and every issue indicator notification light is on. We took the car to our mechanic, then to the Subaru dealership service dept for diagnosis. A full transmission replacement is required plus associated repairs for a cost of $14,543.98. Service estimate attached. This repair is more than 2/3 of the value of the vehicle. This make/model and transmission type have documented problems and Subaru has previously issued an extended warranty on other model years for this same transmission issue. We are trying to communicate with the Subaru customer service but have had limited response due to the holidays and have not had a resolution yet in the past month.
I bought a 2021 Ascent - Touring , lately there was an ever increasing amount of wind noise. It sounded like it was coming from the sunroof, but I couldn't see anything from the inside that looked out of place and there were no signs of water leaking. I finally looked up on the roof from the outside and the weather stripping along the back of the sunroof was coming out. The glue is thin, and didn't even stick to it anymore.. This is an ongoing issue. There are people people on the Subaru Ascent, Facebook Reddit forms that have said they are having the same issue..
Vehicle smells of fuel inside the cabin and when parked in the garage. To date the dealer is unable to diagnose the problem. 60k miles
The transmission/CVT component on the vehicle, 2021 Subaru Ascent is malfunctioning. When being driven, the malfunctioning transmission will cause the vehicle to hesitate in traffic, as well as feeling the slippage of the transmission when in motion. The vehicle also has a burning odor when being driven. NYS inspection was conducted on 10/27/25. The transmission malfunction has been confirmed by a Subaru dealer, who has had the vehicle at their dealership since 11/5/25, 34 days as of today. Subaru Advocacy , whom I have had many calls and emails with, is unwilling to replace the transmission at their cost.
Oil leak from engine constantly from FRONT DIFFERENTIAL, rec cvt pump reseal with new trans seal, pump is leaking causing drips ; drain plug is also leaking. Need to Replace Front and rear Pads & Rotors at 35k miles which is unheard of. Accessed by suberu dealership.
Trunk would not open. Only way to open was to pop open the internal latch access port and switch the latch open with a screw driver. Trunk would not open with key fob, rear handle, or buttons on driver side dashboard.
The contact owns a 2021 Subaru Ascent. The contact stated while driving 65 MPH and attempting to accelerate, the vehicle inadvertently lost motive and failed to accelerate at intended. The vehicle returned to normal functionality, but the failure became a regular occurrence. No warning lights were illuminated. The vehicle was taken to the dealer, who diagnosed a failure with the transmission, and informed the contact that the transmission was slipping. The vehicle was not repaired. The manufacturer was notified of the failure, a case was opened, and the contact was referred to the NHTSA Hotline for assistance. The failure mileage was 75,000. The VIN was not available.
On Friday, June 13, 2025, while (thankfully) in my driveway, the transmission broke on my 2021 Subaru Ascent in my driveway. I simply started my car, put it in reverse, and my car jerked and stopped. NO prior warning. I was on a slight slope. I thank my lucky stars I did not have my kids out on the road when it happened. I had to have it towed to the closest Subaru dealership (a $395 charge). Upon inspection, my transmission (the CVT model) was no longer working. My car was bought in December 2021 and it has around 80,000 miles on it. In researching, I saw that the 2019 and 2020 models with the CVT had been recalled (or had their warranties extended to 100,000 miles coverage) for the EXACT thing that happened to my car. If I am correct, my car was manufactured in November of 2020 from what I was told. I find it so hard to imagine that a transmission should fail due to "no reason" at this point, my car is not even 5 years old! The fact that this has happened on cars right in the timeframe of when mine was made, it's hard to imagine I should have to pay almost $10,000 for a new transmission when the history of these transmissions failing have been quite newsworthy! It was not fixable, the only choice I was given was to buy a new transmission. In today's economy, I just find this unacceptable.
The lane assist failed by over correcting while I have my hands on the steering wheel. It over corrects to the center lane when you are driving with normal behavior. This can cause a collision if it were to over correct while a car was there, this is also easily reproducible in my car.
I have a 2021 Subaru Ascent that falls under an extended warranty regarding the windshield due to a faulty windshield. My windshield has cracked, reduce visibility, and does not allow the forward collision warning to work properly. Subaru recognizes the faulty windshield and refuses to remedy the issue. I question the safety and integrity of this windshield to protect from normal road debris strikes, allow normal visibility, and the integrity of the lamination of the from windshield in the event of a collision.
Every time I go out of park there is a massive clubking noise from under the car. It's actually a super common item with these cars I am seeing as well in other forums. I believe this could lead to sheared parking brakes in the future.
Transmission needed to replaced at around 50k miles. Sister in law has the same year and her transmission went about the same mileage
The windshield on the 2021 Subaru Ascent is dangerous because it chips extremely easily. I purchased the car new in 2021 and since then I have had 7 rock chips (in all different states (TX, CA, WA) and driving conditions/speeds/roads). In the 4 years since I have owned it I have had the windshield replaced twice so I am on my 3rd windshield. Each time the rock hits, it causes a large chip to form which distracts the driver momentarily. It also creates defects in the windshield which could lead to safety issues of the windshield shattering.
Transmission needed a full replacement
Brakes shudder and fade when slowing down from highway speeds. Subaru has issued many "fixes" but it keeps happening. See most recent "Ascent Front Brake Warranty Extension Coverage" it still has not fixed the problem!
Battery draining. Bought car from dealership preowned with 25k miles. Owned it for 3 weeks and so far -Battery dead, jumped it, good for a day then dead again. -took back to dealership, said bad battery, replaced it, good for a week and a half then dead again -scheduling to go to a subaru dealership for diagnoses Ive read about the DCM on these vehicles trying to connect to 3g towers continously even when the car is off. The 3g towers are no longer in use in the USA. Subaru should have a software update to remedy this issue but have not found that thus far. Just a lawsuit over this issue.
I was driving along with no traffic in front of me and no oncoming traffic when the automatic braking system engaged with no vehicles in front of me, this was at 7:42 AM on Monday August 12, 2024. This was not the first time it had done this, but the first time I had the time and no traffic anywhere around to confuse the system. My concern is that if another car was following too closely they would have hit me since there was no reason for the emergency breaking system to engage.
The driver was driving into a parking lot preparing to park, when the vehicle accelerated and started going forward at a higher speed. The vehicle struck a parked vehicle, then travelled across the parking lot, over curbs, a grass median, landscaping, and struck a rock building at a high rate of speed, causing a partial collapse of the wall. The vehicle is available for inspection through the insurance company. No analysis of data was done and nothing was inspected. There were no symptoms of the problem beforehand. The vehicle has automatic emergency braking, but it evidently didn't operate. It is unknown if this was caused by driver error in accelerating and never braking.
Brake rotors, front and back warp. Rotors have been replaced and resurfaced multiple times. The vehicle is over-sized for the braking hardware included with the vehicle. I have spoken to the dealer multiple times and they are aware of the undersized brake component issue across this model line. Although promised, Subaru has not addressed the issue and it is a safety hazard in hilly terrain.
Lift gate began malfunctioning going up and down on its ownthen dropped suddenly onto spouse's head. Now the lift gate does not open properly.
Started having problems with the brand new car shaking and brakes making grinding noises when stopping around 20K miles. Brought the car to the dealership and they ended up replacing the brake pads and rotors. It’s been just over a year and less than 15K miles since the replacement and the car started shaking and brakes are making a grinding noise again. Again took the car to the dealership and the rotors are bad. After further research, this is a constant and known issue and has yet to be resolved by Subaru. Instead they wait for the new car warranty to wear off and let their customers pay out of pocket to have this fixed. Some owners have had to replace up to 4 times in less than 40K miles.
Second time windshield has cracked, not due to rock or debris chip, but from edge of windshield and either out or up. Crack continues to spread until replaced. It is dangerous to drive 1st Incident - December 2022 , crack in middle of windshield, spreading two directions 2nd Incident - May 3, 2024, crack from left side and out, contiunes to spead Pictures attached
Vehicle drifts on the highway and pulls hard to the left, which is a very concerning safety issue. I have already taken the vehicle to the dealer; they did a calibration of the eyesight. The problem still persists, especially when driving the vehicle on the highway. This has almost pulled me into traffic on a few occasions!
Front brakes (pads and rotors) had to replaced 2 times. The dealer said that Subaru used undersized pads and rotors on the bigger Ascent model. The brakes were not designed for such a big vehicle, and it has been a known issue. The brakes were replaced under warranty, but my warranty will expire soon. I'm stuck replacing and poorly designed braking system, that is a known issue.
The contact owns a 2021 Subaru Ascent. The contact stated that while making a left turn at approximately 5-10 MPH, another vehicle ran a red light and crashed into the front passenger's side bumper. The air bags did not deploy. The contact's chest struck the steering wheel, resulting in a fractured sternum. Medical attention was received. A police report was filed. The vehicle was first towed to the police impound lot, then to a body shop. The dealer was made aware of the failure and referred the contact to the manufacturer. The vehicle was not repaired and was not deemed totaled by the insurance company. The manufacturer was not made aware of the failure. The failure mileage was approximately 19,000.
After 3 years the battery died completely and the car was unable to start, I replaced the battery with AAA and the next the day, it also died again. I was able to jump start the battery the next day and continued to use the vehicle. I have the battery for about a month and again the battery on the vehicle had drained where I was unable to start the car but I was able to jump start the car with a battery jump starter. There has been 3 occasions of battery just draining and I have a new battery installed. I called Subaru and they mentioned that there could be an issue with the back latch no closing which could drain the battery, however, the have confirmed that the back door does completely close and lock or it will just automatically come back up. I feel there is something wrong with the electrical system and AAA has confirmed with me the the alternator or the battery is functional.
The vehicle has a parasitic battery draw. I purchased a new gel cell (Redtop) battery, the most powerful one that fits the car, and was reimbursed by Subaru. The car battery still goes totally dead after about one week, even with occasional driving. I have to carry a jump battery in case I am traveling to insure that I can get the car started when I stop.
Vehicle wanders on the highway and pulls hard to the left, which is a very concerning safety issue. I have already taken the vehicle to the dealer, did an alignment and took it back a month later because the issue persisted. The problem persist, specially when driving the vehicle on the highway. I am really concern about my family safety and the safety of others in the road.
Car has always refused to accelerate if gas pedal is pushed down too quickly. Just before 60K miles, on way home we had pulled over at a roadside stop on a hill. Tried to pull across highway to continue up road, car refused to accelerate and luckily were able to brake in time to keep from getting t-boned by big truck heading down the hill. No trouble lights came on, so weren't sure if this was operator failure from pushing gas down on hill or mechanical problem. Also were too close to 60K miles to get home and back to dealership without going over warranty and serious service issues with dealership previously, and leaving for vacation following day. Decided to see if there were further problems. Live at 8K elevation, vacation at half that. No further problems until after returning from vacation. Car definitely hesitating when cold to accelerate at 8K elevation. Checked owners manual, at this time believed appropriate 36K service at dealership had inspected CVT fluid as requested, and was a bit early for next inspection listed in book at 66K miles, but thought perhaps CVT fluid needed changed (did not expect transmission to be failing with such a new car, only a bit over warranty miles now). Because of previous with dealership, instead found ASE certified shop for CVT fluid inspection. Fluid at shop inspection was dark and needed replaced. Shop exchanged with OEM fluid, not Subaru brand. CVT functioned much better for a time, then got worse and not just hesitating with cold but also jerking. Called service shop to insure they had used correct fluid and amount, they had. Brought in to confirm and fluid level was correct. They suspected CVT was failing. Called Subaru of America and made appointment at suggested dealership different from purchase dealership, confirmed transmission failure. Dealership rented car for safety because of suspected CVT failure. Subaru refused to replace CVT under warranty and wanted $7K+ to fix after $3K "discount: Still no trouble lights.
First transmission was replaced after months of trying to get the issue diagnosed. Symptoms included severe hesitation when trying to accelerate, shuttering, and feeling of jerking between gears even though it's a CVT. This escalated to shuttering while driving on the highway. Because the problem was intermittent, my car spent a great deal of time in the shop trying to get a diagnosis. After much back-and-forth with Subaru of America, the transmission was replaced at 48,000 miles. I asked for an extended warranty beyond the 60k warranty due to the fact that it took so long to get the first issue properly fixed. They said no. Less than 3,000 miles later and I'm having the same jerking/hesitation issues. The dealership technician says he cannot duplicate the problem, and SOA still refuses to honor an extended warranty. My 60k warranty is almost up and I fear that I will end up paying for a new transmission or worse, end up in an accident due to the poor performance issues. Subaru will do nothing about this known issue.
P245 / 50 R 20 OEM Falken Tires need to be replaced with only 20K miles, even when all the maintenance was applied (rotation, inflation control, etc). Subaru dealer recognized that the problem was communicated with HQ in Japan, but still not answer
I noticed that the driver's door was making an odd clicking sound when the door was closing. Upon further investigation, I found the silver door bolt holding the door to the frame was loose. I have since then had the bolt tightened.
2021 Subaru Ascent with 15,735 miles on it with the factory Falken tires. The tread and metal was showing and separating from the tires. 2 tires, original to the car off the lot. Tires should last 30-40-50 miles. The other 2 tires were labeled as a 4-5 category. The car did not steer to the left or right, no noise at all. If driving on the highway and 2 tires failed, I could have been injured, my passengers or another vehicle crash. This was very dangerous. In going to the Subaru website and seems hundreds of other customers had the same issue. Failing, inferior, defective Falken tires and alignment issues. I hope these tires don't fail and cause someone to lose their life.
The contact owns a 2021 Subaru Ascent. The contact stated that while his wife was repositioning the rear-view mirror, the front windshield cracked without impact and extended approximately 7-inches. The cause of the failure was not yet determined. The manufacturer and local dealer were not notified of the failure. The failure mileage was 32,000.
Blue smoke from tailpipe upon start
OEM tires that came with original vehicle purchase depleted tread and needed to be replaced by 38,000 miles. Alignment may have been bad from initial manufacturing but is no longer covered by "bumper to bumper" warranty because it is 2,000 miles over warranty. Tire size 245/60R18
Windshield randomly became extremely hazy in one section to the point where Eyesight forward facing obstacle detection turned off. Cerium oxide rubbing compound was required to clear the haze enough for Eyesight to work again. Other sections have less significant haze. It appears to be hairline cracks in the outer layer of the windshield or the windshield scratches extremely easily without any obvious debris impacting it.
Windshield started cracking and crack doubled in size within a few hours, we did not hear a rock chip the window and don't know where the crack came from. Car is available for inspection. This is a safety issue as it can impede the drivers clear view of the road. Will call dealer Monday to have windshield replaced. The windshield has not been inspected by manufacture or insurance. Did not see any warnings prior to failure.
Vehicle braking reduced to about 10%. Brakes was making lots of noise and couldn’t stop for almost 1/4 mile. Managed to stop vehicle was taken to dealer. Calipers were changed and rotors serviced. After several trips to dealership for repairs to brakes vehicle still having braking noise and reduced stopping power which gets worst with time.
Moving glass panel in sunroof cracked. Happened between laminations. Cannot feel crack on either face of glass. Car was parked in parking lot. No visible external impingement or reason I can see. Reporting here after Googl search and seeing other Subaru owners having same issue.
The transmission of my 2021 Ascent regularly slips or shutters when trying to accelerate time to time(not always). Loud noises when shifting from low speed. Went to dealership but they said car working perfectly.
The contact owns a 2021 Subaru Ascent. The contact received notification of NHTSA Campaign Number: 22V9070000 (Electrical System) however, the part to do the recall repair was not yet available. The dealer was made aware of the issue and confirmed that parts were not yet available. The manufacturer was made aware of the issue and informed her that parts were available. The dealer was called back, and the contact was placed on a waiting list. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The contact had not experienced a failure. Parts distribution disconnect.

Adaptive Cruise Control, Automatic Emergency Braking, Forward Collision Warning, Lane Departure Warning, Lane Keeping Assistance, Eye Sight, RAB, some ! Symbol, and check engine light are all on and not working. You know everything that makes a Subaru. This is not the first or even second time. We are on the fourth instance of this happening. We live 2+ hrs away from the closest dealers. The first few times it occurred, we called to make a appointment. Each time was always a few weeks out and the issue would clear a day or two before. This last time has been going on for 6 weeks. We both work full time and have a very sick kid so making a appointment is hard. This last time I asked if I can drop in just for a scan due to being in town for an appointment. Was met with we are backed up with way to many repairs. Also it would not be fair to any other people. It is most likely your gas cap. I have made sure the cap is tight as it can get every time from the first time it occurred. So all safety features on the Subaru Ascent just stop working if the cap is not tight. Not only is this a major safety issue their QA is asleep at the wheel. Known issue, just check the forums.
THE MOON ROOF/SUNROOF HAS LEAKED NUMEROUS TIMES. THE DEALER HAS TRIED TO FIX IT ON THREE OCCASIONS. IT CONTINUES TO LEAK- IT LEAKS WATER INTO THE FRONT EYESIGHT CAMERAS CAUSING THEM TO NOT WORK & CUT OFF SPORADICALLY. THE WATER LEAKS INTO THE CAB CAUSING THE HEADLINER TO BE WET, THE FLOORBOARD AND THE ENTIRE CONSOLE AND CUP HOLDERS FILLS UP WITH WATER. I HAVE HAD IT AT THE DEALERSHIP ON THREE OCCASIONS DEC 2012 JAN 2021 NOV 11 2022 AND IT HAS NOW HAPPENED A 4 TH TIME ON NOV 15 2022 AND IS STILL NOT REPAIRED. I HAVE BEEN WITHOUT MY VEHICLE FOR 34 DAYS. IT HAS LESS THAN 18,000 MILES ON IT.
Car would not start in morning. @20,000 miles. Battery dead..not even trying to turn over..Had to get car jumped then all safety features went dead..looked on Subaru sight and it showed every safety feature disabled..I did not drive car till next day to bring to dealer..next day all features fine like nothing happened..Dealer found nothing wrong. Dealer tested battery and showed fully charged..
I noticed the windshield of my Ascent premium has thousands of millions of glaring specks/dots when facing the sunlight in early morning or late afternoon. The windshield becomes so blurry and extremely annoying. This happens only in early morning when facing the sun or late afternoon.
The contact owns a 2021 Subaru Ascent. The contact stated while driving at 65 MPH, the vehicle shut down completely. A message indicating that the vehicle had unexpectedly stopped, and to check the vehicle as the remote start had failed was displayed. The contact was able to veer to the side of the road safely and waited until the vehicle cooled down. The contact restarted the vehicle and continued driving. The vehicle was taken to the dealer where it was diagnosed that no issues were found. However, the failure reoccurred several times while driving. The vehicle was not repaired. The manufacturer was contacted and informed the contact that they could not assist as the dealer diagnosed that no issues were found. The failure mileage was 300.
The battery constantly drains when the car is not in use for a very short time. It appears to be an electrical drain. I have already replaced the battery two times and the car has less than 15,000 miles. Apparently this is the same problem as in the 2016 - 2019 class action suit.
I found a lot of oil leaking from the oil filter cup and that would splash all around the filter area. I brought the car at the dealership and they have replaced the filter but when I checked after few days ( smoke was coming out of the hood) there was oil all over again. I bought an aftermarket filter and I installed it myself. No one drop of oil found. So I believe this a is a safety concern because the oil might catch on fire with the heat of the engine. I believe a defective oil filter design or a bad technician training or both are causing the problem.
The battery died after 2 years and 15000 miles. I was with my whole family ( 2 months old, 2 and 4 years old) away from home. I was able to reach the dealership leaving my family in a store and they said that nothing was wrong with the battery. Next day the car wouldn’t start and they finally replaced the battery under my extended warranty. Today I discover that there is a class action settlement for older models of my car. I was advised to write a complain to you. Apparently they didn’t fix the problem with newer models either.
Car purchased in August 2021. Front brake rotors and pads were replaced around 7,600 miles and May 2022. They could not "cut" the rotors as they were pitted beyond being able to be cut. At 10,764 miles (August 8, 2022), the front rotors and pads were replaced again. The dealer stated the front pads had tiny chips in them and the R/F outer pad had a crack in it. The rotors also had excessive heat spots on them and small pits. The last few days the brakes have been pulsating lightly on hills and today have begun pulsating at every stop. Car now has approximately 11,700 miles on it. Subaru has been notified and I will be making an appointment with dealer on Monday.
Car purchased in August 2021 new. In May 2022, the car had hesitation problems when traveling between 15-30 mph. The car was taken into the dealership with approximately 7,600 miles. Dealer had a Subaru field tech review data as they saw transmission slippage at basically all speeds. Suggested to reprogram the transmission. We were advised to drive it and let it "relearn" the reprogram. The transmission slipped but not as bad with reprogram until about 150-200 miles later. The slippage was even worse and immediately taken to the dealer. The dealer found metal particles in the transmission fluid and replaced the transmission. A loaner was provided for approximately 2 weeks and work was completed. Car has been better and we were told we just need to get used to the CVT on this car. On 9/10/2022 with approx 11,700 miles, we were driving around town and experienced slippage of transmission just as bad as the original faulty transmission. Car is parked and appointment will be made with dealer to check. Subaru was notified as we are also experiencing brake problems.
Windshield is extremely soft and cracks easily. In less than 1.5 years I've owned the car I've gotten 3 chips/cracks and now a 4th major one that requires a full replacement. No car previously owned ever had this issue, not even the previous Subaru. After searching online this seems to be a common problem in Subarus, as there was a class action suit for earlier models. Yes, car is currently available for inspection until repaired. Super soft windshield - if the windshield is broken completely on a highway, it's obviously a concern and a risk. Have not taken the car in yet, but will be to get it replaced.
I have a 2021 Subaru Ascent Premium with 6,000 miles. The Transmission or CVT feels odd every time i shift from Park to Drive or Reverse i feel a hard clunk additional to that every time i get in the Highway and add some RPMs to the SUV the CVT shifting feels Hard more likely like i m driving a Manual vehicle something that is not suppose to happen or feel that way. I took it to the dealer and they only found that the part that press tp brake to shift was not lubricated ( no clue the real name) and they also mention that is how the CVT works something that i don't think so and they also mention to wait for a recall.
Without anything noticeable hitting the windshield, it was fine on July 2nd 2022 and when I went to get in to drive the next morning there was a crack in the windshield.
Vehicle will jerk and shudder when accelerating and de-accelerating. Mostly between 15mph and 30mph. I’ve taken the vehicle back to the dealership and they didn’t find the issue. This prompted me to do some research online and found in one of many. There is a class action lawsuit for 2018-2019 Ascents. The 2020-2021 and 2022 models will follow suit as they have identical issues. I’m concerned the transmission will fail and I’ll have a lemon on my hands. The sudden loss of power to sometimes sudden acceleration by suddenly downshifting is a concern. The vehicle will often hesitate while it tries to figure out which gear it needs. This has been happening since day 1 of ownership.
Purchased 2021 Subaru Ascent Limited outright, drove it for few months, started having pain in my right thigh that resulted in cramping and severe discomfort which affected my ability to feel the break pressure. This nearly ended up causing a couple of near miss rear end collisions. The pain got so bad that it caused me to lay prone and apply muscle cream to the affected area then remain prone for like 15 minutes before being able to continue driving until the pain returns. I consulted my Doctor and went through all the hoops to get an MRI, steroids, pain meds, heating pads, etc, without results or elevation. Ive tried cushions, padding and every possible seat adjustment still without any relief. I am scheduled for surgical consultation over this matter with strong possibility of surgery. There are thousands of Subaru owners throughout the web suffering from this same issue which has been medically classified by physical therapy professionals as " Subaru Sciatica Syndrome". The poorly designed seat has hard bolsters that jam into my thigh causing the sciatic pressure that causes the abnormal break pressure sensation. Therefore meeting two requirements for investigation. Subaru USA is aware of this problem and has banned me from posting anything educational on all their websites informing owners to the solution and action available. I had the seats looked at by an experienced car upholstery shop and repairs were estimated, submitted to Subaru upon their request, only to be denied.
April 25, 2022: The trunk/liftgate of the vehicle failed to detect an obstruction and closed without retracting when it came in contact with an individual's head. The impact caused a head injury, blackout, and concussion, and resulted in permanent damage to an individual (6' 2" - 190lbs). Subaru’s stated that an inspection of the vehicle was performed on May 19th and informed me that “the vehicle is operating as designed…and has met all federal specifications,” and that their inspection concluded that this is “no manufacturing defect.” Prior to the inspection, Subaru requested signed consent to inspect the vehicle's internal data which I provided. When I requested a copy of the report, Subaru informed me of their policy not to share this information despite the vehicle "operating as designed." One of the first things that we learn about computers is “Garbage in, garbage out.” My position is that if Subaru’s computers are not programmed to look for issues pertaining to incidents that contradict their message of superior safety features, then their computers will not find issues that do not reflect their preferred image. No warning messages or symptoms prior to this occurrence. Subaru's response is included in this report.
The Transmission on the vehicle was exhibiting excessive noise when shifting from park to drive and was progressively becoming undrivable with odd shifting, hard shifting, RPM fluttering, and chugging. It made progressively louder audible sounds and squeaks during cold starts when shifting from park to drive. It was brought in for service and the original transmission was replaced due to metal shavings found in the case, a direct indication of failure, with no warning lamps or codes from the onboard computers. After approximately 500 miles, the replacement transmission is exhibiting the same progressively worse drivability issues and transmissions sounds. I returned to the same dealership for service and they said they did hear the issue but needed a field technician to diagnose the issue. I have contacted the servicing dealership and Subaru America's directly and after 6 weeks, they have continued to tell me they will try to get someone to look at it, but will not set a date or time. They have refused to provide any written documentation around the issue and will not issue a repair order stating the vehicle is operating normally even after directly requesting it from both the dealer and subaru america. They have stated the documentation is internal only and cannot be shared with the consumer. The replacement transmission has 3,000 miles at this point and is exhibiting the same progressive failures. The vehicle feels unsafe because the transmission behavior is now unpredictable and erratic.
It is actually the lane centering system. Even a gentle hand on the wheel, which is required, will gradually pull you to one side of the lane. When ever you lift your hand or when the car thinks you have gone to far one way or the other it will throw you into the other lane, into a car, motorcycle, semi, or even off a cliff. This system is so dangerous I cant believe it hasnt been recalled. If using this you will get thrown one way or the other several times during most trips. Dealer states its normal and I got that in writing.
The contact owns a 2021 Subaru Ascent. The contact stated that while the daughter was driving approximately 20 mph and making a slight right turn, the steering wheel did not respond and the vehicle drifted to the left and crashed into the guard rail. Prior to the incident the driver indicated the steering wheel felt wobbly and unstable. There were no injuries reported. The police was called to scene and the vehicle was towed away. No further information was available. The cause of the failure was not determined. The manufacturer and local dealer were not notified. The failure mileage was 10,000.
The battery went dead even though the car was parked in the garage and had been driven recently. AAA was called to jump start it. The vehicle only has 5k miles on it, so it shouldn’t be having battery problems. We are lucky this happened at home.
My mirror on my car has started melting. They told me it was a outside force, from a lighter. I told them it was electrical or something wrong from the inside of the mirror. There are forums recently posted up regarding this and Subaru has ignored them all claiming it is reflective light from the sun. That they can’t do anything about it. Others have replaced their mirrors 3 times now. This is a potential fire hazard and could be unsafe. They are not addressing this as it should be. https://www.thesubaruforums.com/threads/melting-side-view-mirror.12397/
Unknown. I am smelling gasoline in the cabin of the car. A LOT of fumes fill my garage when I start the car. The car sometimes accelerates when I put it in park, resulting in more fumes. Fuel efficiency is lower than expected as well.
The car constantly over-corrects when it tries to keep me centered in a lane on the highway. It always over-corrects to the left shoving me to the left into the adjoining lane, and potentially side swiping vehicles in the adjoining lane. It never over-corrects to the right. I reported this to the dealer and I was told that this is normal.
At 1 month old with 1,661 miles - the driver's side window started showing a cracked line that began to grow throughout the course of driving on a Saturday afternoon.
The lane keeping assist pull abruptly into the other traffic lane when traveling on the highway for example when on a 4 lane road with two lane in the same direcstion and passing a semi truck the steering assist abruptly pulls the car into the truck's lane and requires immediate hard handed reaction to keep the car from hitting the truck. The lane assist on this subaru vehicle is more dangerous than it is helpful. Subaru is terribly un response to request for help although the car is less than 1-year old and has a mult-year extended warranty---subaru's customer service is the worst we've experienced. BTW my son's Honda Acura's lane assist is excellent!
When operating the 2021 Ascent, I experience intermittent problems at various shift-points in the CVT and at various RPMs. The transmission seems to shudder and slip between shift-points, and the shuddering sensation is so severe that it transfers up through the steering column and the steering wheel shakes. I have brought the vehicle to my dealership (Kocourek Subaru in Wausau), and they have acknowledged that the shuddering is taking place and even documented it in the 18K service invoice. They ran it through the protocols for NHTSA TSB 10185089, and were not able to achieve fluctuation in the gear ratio. Since the TSB test, the dealership again took the vehicle and has had it for ca. three-weeks, and have tested it, replicated the issues described above, downloaded data, sent data to Subaru of America, replaced some kind of sensor associated with the CVT, and sent additional data to Subaru of America, and are awaiting a response from SOA as to the next steps.
The contact owns a 2021 Subaru Ascent. The contact stated that after the vehicle was parked in the garage, the contact returned to the vehicle and noticed a crack on the windshield. The crack was on the lower driver’s side of the windshield and moving upward. There was no impact to the windshield to cause the fracture. The vehicle was taken to the dealer but was not yet diagnosed. The vehicle was not repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 3,141.
On several occasions while using the lane centering feature, vehicle has taken a sudden violent move to the left into the on coming lane. No warning lights illuminated. Problem hasn’t been replicated by dealer.
Three chips have showed up on my windshield. I called the dealer when I saw it. They said all customers pay out of pocket. Then I recently saw that there is an issue with the windshields. That Subaru corporate is now taking care of the issue. I am looking for information to move forward with getting my windshield fixed. It happened a few months ago.
The contact owns a 2021 Subaru Ascent. The contact stated that while reversing out of the driveway and making a left turn, the steering wheel locked up and the contact could not turn the vehicle. The contact restarted the vehicle and the steering wheel to unlocked. The failure recurred with an unknown warning light illuminated. The contact took the vehicle to the local dealer to be diagnosed. The contact was informed that the rack and pinion needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was 6,200.
The windshield cracked without impact.
Hello, my vehicle 2021 Subaru Ascent Limited with Navigation Package had it's panoramic sunroof cracked while the vehicle was parked in the garage. Upon researching the internet, it appears that this issue is systemic design or material flaw for Subaru vehicles. Reference: https://www.torquenews.com/1084/subaru-cracked-windshield-lawsuit-grows-25-million-us-vehicles Is there a way NHTSA can help get the issue addressed? Thank you!
On our first road trip in our new Ascent the windshield cracked. It rapidly spread about 18 inches. We heard no impact, saw no rock - just an ever spreading crack. We called a local Subaru dealer in Lexington, Kentucky who assured us the car was safe to drive home to Savannah. On the trip home we encountered a heavy rainstorm and noticed leakage at the crack. I am filing this after seeing the large number of Subaru owners reporting similar occurrences. We had just experienced another cracked windshield on a 2019 Subaru outback that we had repaired on 11 May 2021! There is something not quite right about this windshield in the Subarus.
After leaving liftgate open for a while, battery was dead. Learned from website that this was known issue for Subaru’s with automated liftgate. As i was camping with no cell signal, it was super difficult to get help and this could lead to the really big issue. This is the known issue for a while and I was shocked to Leane that Subaru did nothing to fix this.
I purchased the vehicle Oct 2020. Since then the windshield has sustained 6 chips/cracks in the windshield. I found this to be unusual since I maybe have gotten 2 cracked windshields in 20+ years. I stared researching and found out this is an ongoing problem with Subaru windshields. I went to the dealer and was told they can do nothing about it. Appreciate any help.
LANE ASSIST WITH CRUISE CONTROL OVER CORRECTS. ON MULTIPLE OCCASIONS WHILE ON THE FREEWAY USING CRUISE CONTROL THE LANE ASSIST PULLED ME INTO THE OTHER LANE INTO OTHER VEHICLES. I HAVE ALMOST HIT OTHER VEHICLES. THE PULL IS TOO STRONG AND CROSSES LANES. IF NOT FIXED BY SUBARU, ACCIDENTS WILL OCCUR.
CRACK APPEARED SPIDERED ACROSS THE WINDSHIELD JUST WITHIN THE 60 MINUTES OF US LEAVING OUR CAR IN MAMMOTH CAVE STATE PARK INFORMATION CENTER PARKING LOT ON SATURDAY. SUCH A TINY CRACK SPIDERING LIKE THAT IS CONCERNING TO ME ESPECIALLY COMING FROM A 2015 SUBARU LEGACY THAT HAD THE NEW WINDSHIELD CLASS ACTION. WE DID NOT SEE THAT CRACK AT ANY TIME BEFORE. THIS WAS PURCHASED IN THE END OF FEBRUARY.
LANE ASSIST WITH CRUISE CONTROL OVER CORRECTS. ON MULTIPLE OCCASIONS WHILE ON THE FREEWAY USING CRUISE CONTROL THE LANE ASSIST PULLED ME INTO THE OTHER LANE INTO OTHER VEHICLES. I HAVE ALMOST HIT TWO OTHER VEHICLES. THE PULL IS TOO STRONG AND CROSSES LANES. I HAVE TO KEEP IT OFF. FORWARD COLLISION DOES NOT ENGAGE.
THE 2021 ASCENT HAS LANE CENTERING ASSIST WITH VERY STRICT MARGINS. IT IS A CONSTANT TUG OF WAR WITH THE VEHICLE WHEN LANE CENTERING IS ACTIVE. WHEN YOU LET THE CAR TAKE OVER, IT VIOLENTLY JERKS YOU INTO THE NEXT LANE. THIS PROBLEM HAS BEEN CROSS CHECKED WITH OTHER USERS ON A SUBARU FORUM AND ALL HAVE THE SAME ISSUE. THE CAR OVERCORRECTS AND IS PRONE TO CAUSE AN ACCIDENT AT SOME POINT. I AM LUCKY NO ONE WAS IN THE LANE NEXT TO ME WHEN THE CAR SWERVED ME INTO THE NEXT LANE. MY 2021 IS A REPLACEMENT OF A 2020 MODEL BECAUSE THE 2020 WAS DEEMED A LEMON. THE 2020 MODEL DID NOT HAVE LANE CENTERING BUT LANE KEEP ASSIST INSTEAD. THE 2020 DID NOT VIOLENTLY JERK INTO THE NEXT LANE. THIS ISSUE HAS BEEN REPORTED TO LESLIE KARPIAK AT SOA WHO HELPED ME THROUGH MY LEMON ISSUE ON THE 2020 MODEL. I REQUESTED A FULL BUY BACK AND SHE SUGGESTED I HAVE MY CAR INSPECTED AT A DEALERSHIP, BUT THAT IS A LENGTHY PROCESS AND I HAVE ALREADY SPEND 3 MONTHS IN AND OUT OF DEALERSHIPS WITH MY 2020 MODEL. THIS APPEARS TO BE A COMMON ISSUE ON ALL 2021 MODELS AND SHOULD BE INVESTIGATED FULLY. I AM HOLDING SUBARU 100% LIABLE WHEN AN ACCIDENT OCCURS BECAUSE OF THIS LANE CENTERING ISSUE. THIS ISSUE HAPPENS ON A CONTINUOUS DRIVING BASIS. YOUR HELP AND ASSISTANCE IS GREATLY APPRECIATED FOR THE SAKE OF SAVING LIVES.
THE LANE ASSIST FEATURE (ONLY AN OPTION WHEN USING ADAPTIVE CRUISE CONTROL; NOT THE SAME AS LANE CENTERING WHEN NOT USING THE ADAPTIVE CRUISE CONTROL [THE BASICS LANE CENTERING WORKS JUST FINE]) SEEMS OVERLY AGGRESSIVE. EACH TIME I HAVE USED LANE ASSIST WITH CRUISE CONTROL, IT JERKS THE CAR VERY ABRUPTLY AT TIMES, ALMOST TO THE EXTENT OF SENDING IT INTO ANOTHER LANE IF I DO NOT INTERVENE. I NO LONGER FEEL SAFE USING LANE ASSIST, SO I TURN IT OFF WHEN USING CRUISE CONTROL. I AM VERY CONCERNED IT'S GOING TO CAUSE AND ACCIDENT. THIS HAS HAPPENED AT LEAST 5 TIMES NOW WHILE DRIVING ON THE FREEWAY (EVERY TIME I HAVE ATTEMPTED TO USE LANE ASSIST).
VEHICLE WANDERS ON THE HIGHWAY. WHEN PASSING A VEHICLE ON THE ROAD THE LANE CENTERING ASSIST TRIES TO HUG THE CENTERLINE AND THE DRIVER MUST KEEP PULLING HE VEHICLE BACK TO THE CENTER OF THE PASSING LANE. A SHORT LAPSE OF STEERING COULD PULL THE VEHICLE INTO THE SIDE OF THE VEHICLE BEING PASSED. FULL TIME JOB TO KEEP THE VEHICLE FROM WANDERING WHEN VERY LIITLE WIND AND ALMOST IMPOSSIBLE TO KEEP IT FROM WANDERING WHEN THE WIND IS BLOWING 15-20 MPH. NOT A PLEASANT RELAXING DRIVE.
WINDSHIELD IS CRACKING FOR NO APPARENT REASON, STARTING AT THE BASE OF THE DRIVER SIDE CORNER AND SPREADING 2-5 INCHES PER DAY. NO IMPACT POINT IN WINDSHIELD.
AT 1667 MILES ON MY BRAND NEW SUBARU ASCENT THE BATTERY WAS COMPLETELY DRAINED WHILE MY WIFE WAS OUT SHOPPING. THE BATTERY NEEDED TO BE REPLACED. NO CHARGE TO ME, HOWEVER AT 1667 MILES THAT IS AN ISSUE. THERE IS A DEAD SUBARU ASCENT BATTERY CLUB THAT N FACEBOOK DEDICATED TO THIS ISSUE AND LAWYERS STARTING TO GET READY FOR CLASS ACTION LAW SUIT. VEHICLE WAS PARKED WHEN THIS HAPPENED. DEALER COULDN'T EXPLAIN WHAT HAPPENED.
MY WIFE PARKED THE VEHICLE AND WHEN SHE WENT TO START IT THE BATTERY WAS DEAD AT ONLY 1667 MILES.
THE WINDSHIELD OF OUR NEW SUBARU ASCENT TOURING 2021 JUST CRACKED ON ITS OWN ONLY A COUPLE OF WEEKS AFTER PURCHASE. THE CRACK IS NOW ABOUT 10IN AND KEEPS GETTING LONGER((
TL* THE CONTACT OWNS A OWNS A 2021 SUBARU ASCENT. THE CONTACT STATED THAT WHILE DRIVING AT MID LEVEL SPEED, THE CONTACT HEARD AN ABNORMAL NOISE COMING FROM THE WINDSHIELD. UPON INSPECTION, THE CONTACT NOTICED THAT A CRACK HAD INFORMED ON THE DRIVER'S SIDE WINDSHIELD RIGHT ABOVE FRAME. OVER TIME, THE CRACK EXTENDED FROM THE DRIVER'S SIDE TO THE MIDDLE RIGHT BELOW THE REAR VIEW MIRROR. THE CONTACT STATED THAT THE CRACK OBSTRUCTED HER VISION WHILE DRIVING. THE CONTACT CALLED SPORT SUBARU SOUTH (9951 ORANGE BLOSSOM TRAIL, ORLANDO, FL 32837) WHERE THEY INFORMED HER THAT THEY WERE UNABLE TO SERVICE THE VEHICLE. THE CONTACT ALSO ATTEMPTED TO REACH THE MANUFACTURER BUT SHE WAS UNABLE TO REACH A REPRESENTATIVE. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS APPROXIMATELY 360. THE VIN WAS NOT AVAILABLE.
OUR WINDSHIELD ALREADY HAS NUMEROUS CHIPS AND ONE CRACK THAT WE REPAIRED. WE HAVE ONLY HAD THIS CAR SINCE OCTOBER BUT IT SEEMS LIKE THE WINDSHIELD IS VERY BRITTLE. WE HAVE HAD SOME WINTER WEATHER LATELY SO THERE WAS EXCESSIVE JUNK IN THE ROAD AND SAND BUT OUR OTHER VEHICLES HAVE NOT HAD THE SAME ISSUES.
