ODI #11708921ENGINE,FUEL/PROPULSION SYSTEM

Trying to understand why a recall was not done on an engine issue on this car and instead GMC chose to send out 2 letters in 2024 detailing the problem that "might" happen with the engine losing power while driving and for owners to "carry" the letters in the glove compartment of the vehicle so the dealership could be aware of the issue. You were told to not bring the car to be serviced unless the issue was obvious. Well it happened when I was out of state and had to immediately find a GMC dealership to fix the issue for which my car was in a dealership in [XXX] for approximately one month. If the proper recall would have been made I would NOT have driven the car out of state prior to getting it fixed. I had family members in the car with me at the time and to lose power on an interstate was very scary to say the least. I feel that GMC failed it's customers with this vehicle and I will never buy another GMC vehicle or for that another vehicle US made vehicle. The issue was fixed at GMC's expense but they are now failing to reimburse proper funds for the rental I had to use putting a burden on my finances...be that as it may I am totally disappointed with the Buick Encore GX 2021. You try to support the "american made label" and this is where it got me for trying to do the right thing...I feel no one is looking out for the consumers on this particular issue b/c I'm pretty sure I'm not the only one it has happened to...A RECALL SHOULD HAVE BEEN DONE ON THIS ISSUE..!! This is 2021 with fewer than 48,000 miles and up to date services by reputable GMC dealerships since I have had the car. The case # with GMC for this issue is XXXINFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

This is an ongoing issue that I have brought to the NHTSA's attention before, which resulted in a special coverage program being issued; however, now GM is not willing to assist me with the special coverage program due to a branded title (used vehicle), and the condition is only getting worse. Tonight, on August 16th, my vehicle experienced a complete loss of power, including engine functionality and fuel/propulsion systems. This stems from the original complaint I filed last fall (11614068) in relation to the turbocharger. I was advised by GM that they would not service my vehicle multiple times by rude supervisors, as my vehicle did not qualify under the special coverage because it's not a "safety issue:", and that the NHTSA has not issued a safety recall for this issue, when it's a safety issue. This is outrageous, and I URGE the NHTSA to look into the severity of this issue. It's only a matter of time before I am on the highway when my vehicle experiences what it did tonight. A complete loss of power, engine functionality, and the fuel/propulsion systems. I already had a near-death experience while driving on the highway when my engine power was reduced, which caused me to go from 65MPH to 40MPH in seconds on a highway, in the left lane, and I almost got rear-ended by someone going 75MPH. This is a safety issue, and it's not just impacting me. I find it so misleading that GM sent me a legal letter stating they knew there was an issue with the turbocharger and that they would take care of the repairs at no cost to me. The first line on the legal document states, ' Your satisfaction with our product is important to us," unless your car is used and has a branded title. There is nothing on that special coverage notice that explicitly states your title must be clean. I urge the NHTSA to issue a safety recall on the turbocharger so other Americans like me don't have to spend months going back and forth to get a simple repair done, an essential safety repair.

Turbo charger has gone out 4 times since I purchased it in April 2021. I have been on the interstate driving and suddenly my car slows down and a message that says “engine power reduced” comes up and my check engine light comes on. This is dangerous as I was on the interstate with 18 wheelers and could’ve been rear ended and badly hurt or killed. My grandchildren could’ve been in the car with me. When this happens the vehicle slows down considerably and does not accelerate properly. I have to drive in the right lane at a much slower speed putting myself and others in danger. Leachman Buick in Bowling Green, KY has repaired the car twice. Campbell Chevrolet in the same city has repaired it twice and it is currently at this dealership due to the engine power situation occurring again. This has caused me severe inconvenience as I have had to drop my car at the dealership several times in the past few weeks and rearrange my schedule as a rental car has not been provided. Campbell Chevrolet repaired the vehicle a few weeks ago and the check engine light and reduce power message was back on within 6 hours of them initially completing the repair. Two weeks or less it was the waste gate actuator solenoid that was replaced but the engine message and check engine light are back on. I am VERY FRUSTRATED at having to jump through hoops regarding this vehicle. I own the Bluegrass Edition model and it is obvious that something serious is wrong with the car and Buick needs to recall the car IMMEDIATELY. It is either a lemon or something else is causing the turbo charger to repeatedly fail. I have taken the car to TWO different dealerships and neither one of them have been able to rectify the issue long term. The vehicle needs to have a TOTAL diagnostic test on EVERYTHING relating to the engine and power system. PLEASE LOOK INTO HAVING THIS VEHICLE RECALLED AS I DO NOT WANT TO LOSE MY LIFE ON THE INTERSTATE DUE TO REDUCED ENGINE POWER AND MY CAR AUTOMATICALLY SLOWING DOWN!!

I'm in need of a repair on my 2021 Buick Encore GX. It was seen at GM of Marion on July 30 for a warning light that came on as I was driving down the road after having an oil change. It stated my power was reduced. I took it in, and they told me they had just diagnosed this problem for another Encore owner, and it took two weeks to get the part in. It is now September 22, and I still do not have this fixed. It is a safety concern and I have been calling GM about it almost weekly, trying to get some help. How is it safe for my daughter & I to be driving down the road with only half power? I cannot pass anyone - the speed isn't there. I can't just pull out or even merge onto the interstate for fear of being ran over. And GM does not appear to care. I've been told by multiple dealerships that GM has them. They just will not freely send them out to dealerships to repair cars. I think if they have a car sitting on their lot that has the part, they should be allowed to use it to take care of the one that is already sold. I'm at 31,000 miles, and they told me it may not be covered if I am outside of my warranty when they decide to send the part. I need some help!

ODI #11420749SERVICE BRAKES

This week I leased a white buick encore gx fwd in the preferred model. After driving off the lot I noticed the brakes are very hard to press down and I can’t stop the vehicle over short distances. This seems dangerous and my dealership says nothing is wrong with the car but I can tell something is wrong with the brakes and this isn’t how new brakes are supposed to feel. After googling the symptoms it seems to be a problem with the brake booster.

ODI #11420627SERVICE BRAKES

The brake system failed upon pulling into a parking space. Had it happened a few, short moments before, there would have been a high probability of a crash. The vehicle was taken to Hardy Buick GMC Chevrolet. Upon reading the codes, I was told that the vehicle needs a new master cylinder. (It has only 672 miles on it and I've owned it less than 3 weeks.) Numerous lights came on, including: Brakes, ABS, Traction Control, Engine, as well as 2 others. A message came up on the screen that said, "Brake System Failure, 62 MPH Top Speed." There were other messages that cycled that I did not get to make note of, but one made mention of "power steering." Upon research, I found that there are recalls on certain 2021 Buick Encore GX's for an issue related to brake system failure. I was told, based on my VIN number, that my vehicle is not included in that specific recall, however, when my brake system failed, it did exactly as what was described as the potential consequences of the brake failure issue in the vehicles recalled.

Chart Analysis

The blue line shows 43 total NHTSA complaints filed over 6 years, with the worst year being 2025 (14 complaints).

The amber reliability line is declining — recent years score around 31/100, lower than earlier in the vehicle's life. This pattern indicates issues are accumulating over time rather than being resolved, which is a concern for used buyers.

The recall (red dashed line) were issued in the same year or before complaints peaked, suggesting the manufacturer identified and acted on the defect relatively quickly.

Red dots on the amber line flag 2 years (2022, 2024) where complaints included crash events — these are the highest-severity incidents in the dataset.
