VERIFYCriticalTiming Chain Tensioner
Typical interval: 120,000 mi / 10 yr · Verify service records (no odometer on file)
Verify timing chain tensioner service history with the seller
Worn chain tensioners cause timing chain skip or snap — common on GM 5.3L/6.2L, Ford EcoBoost, VW/Audi EA888, BMW N47/N63. Listen for cold-start rattles.
VERIFYCriticalWater Pump
Typical interval: 100,000 mi / 8 yr · Verify service records (no odometer on file)
Verify water pump service history with the seller
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.
VERIFYHighTransmission Fluid / Service
Typical interval: 60,000 mi / 5 yr · Verify service records (no odometer on file)
Verify transmission fluid / service service history with the seller
Degraded transmission fluid destroys clutch packs and solenoids. CVT transmissions are especially sensitive — neglected fluid can result in a $4,000–$8,000 replacement.

Typical interval: 50,000 mi / 4 yr · Verify service records (no odometer on file)
Verify differential / transfer case fluid service history with the seller
On 4WD/AWD vehicles, neglected differential or transfer case fluid causes metal-on-metal wear. Replacement costs $1,500–$4,000.

The vehicle experiences harsh shifting, surging, and jerking forward during normal driving conditions. The behavior has occurred repeatedly over several years and has been confirmed by the dealership. Multiple repair attempts, including transmission-related work, have not resolved the issue. The vehicle has surged forward unexpectedly, creating near-miss accident situations. I no longer feel the vehicle is safe to operate.

These vehicles have an issue tbat GM is aware of, with their 8 speed automatic transmissions which are used in multiple GM vehicles and these cause safety issues because for instance my vehicle switches gears randomly almost causing a wreck, and shuttering, and even slipping and when this happens the cars traction control light is engaged shutting it off, active steering is also shut off due to these on going issues. Im in a cadillac group and hundreds of us have similar issues.

ODI #11532575POWER TRAIN

The car is equipped with an 8-Speed Automatic Transmission which is frequently very hard shifting from 1st to 2nd gear. The car has been to my local Cadillac Dealer twice for this problem; they reply this is a know problem, and a normal condition, but the problem is getting worse. I'm concerned for the future and afraid of an accident because of a transmission failure.

ODI #11530777TIRES

SIDEWALL CRACKING ISSUE WITH ALL FOR TIRES - PIRELLI P ZERO NERO 245/40/R20 While traveling out of town (Dallas to San Antonio) we experienced some tire issues which led to us needing to replace all 4 tires. Several weeks prior, we began to noticed a very slight loss of tire pressure and had the tires checked twice for any objects or other damage – Nothing found. We also had the tires rotated to trouble shoot and rule out any issues with sensors – none. Both times, the service shops did not mention or recognize any tire damage or issues. During our 5 hour drive to San Antonio, we started to see tire pressure issues again along with a noticeable sound from the tires. With this concern, we took vehicle to Firestone for diagnosis and to our surprise they found severe damage and cracks to the side walls of the tires. Firestone confirmed the tire damage was not safe to drive on and due to the location of the damages, we would need to replace all 4 tires. We were shocked to see such severe cracking damage and were at a loss for how this could occur. The tires were in very good condition and still had significant tire tread with even wear. After some research we discovered that this type of side wall tire cracking has been know to happen and even Pirelli has recalled tires for this issue. We did not see a specific recall to this size tire but did find that Pirelli had another recall on tires made in 2016 saying "THE PROBLEM WAS CAUSED BY A PRODUCTION ERROR (INCORRECT CARCASS COMPONENT), AND THE TIRES MAY SHOW SURFACE CRACKING IN THE LOWER SIDEWALL OF THE TIRE...". Please review this claim and confirm receipt. We are hoping to get some kind of reimbursement for the damages that we believe are a result of faulty or defective tires - this is what the Firestone technician also stated on video recording (I can provide video if needed).

I was driving the vehicle heading to the interstate, and my speed was about 15 MPH, as I merge onto the highway and accelerated I felt the transmission shudder, and lag with a humming noise. It felt like the transmission mission was slipping and shaking with no acceleration power. I had to keep hitting the gas pedal to try and make the transmission engage. Very Dangerous! The transmission would also throw you back and jerk when accelerating violently. The transmission lunges forward and jerks into gears when starting from 0 mph.

While driving the vehicle with auto stop engaged, the auto stop was malfunctioning. When I get to a red light or stop sign vehicle would engage auto stop, once I let my feet off the gas pedal and accelerate, the vehicle would jerk out of gear then slip /drag then engage with a loud hit as if someone rear-ended me. The problem was duplicated and confirmed by the dealership. There has been no outside inspection other than the dealership. No warning lights messages prior to failure. In addition, the Auto-stop working with a week of this complaint shortly therafter.

The contact owns a 2017 Cadillac CT6. The contact stated that while driving at various speeds, the vehicle would hesitate upon depression of the accelerator pedal without warning. The contact had taken the vehicle to a dealer where they initially changed the transmission fluid and reprogrammed the transmission module; however, the failure persisted. The contact returned the vehicle to the dealer and she was informed that the torque converter was defective; but that the cost to replace the transmission was expensive. She was advised to bring the vehicle back to dealer each time the hesitation occurred to have the transmission fluid replaced. The manufacturer had yet to be notified of the failure. The vehicle had yet to be repaired. The failure mileage was approximately 14,000.

Chart Analysis

The blue line shows 26 NHTSA complaints on file for the CADILLAC CT6 — a relatively low volume that spans from 2017 to 2026.

The amber reliability line averaged 97/100 across the vehicle's life — relatively stable, with the lowest point of 95/100 in 2025.

Notably, despite 26 complaints on file, no recall has been issued — either the defect pattern has not met NHTSA's threshold for a formal campaign, or a recall may be forthcoming.

GM 8-Speed Transmission Shudder Special Coverage
Transmission – 8L90 / 8L45 8-Speed Automatic
COVERAGE:7 years / 100,000 miles from original sale date

8-speed automatic transmissions (8L90 and 8L45) exhibit a shuddering or shaking sensation during light acceleration, especially at highway speeds. GM issued multiple TSBs and extended coverage programs. The fix involves a fluid exchange with a revised fluid formulation and, in persistent cases, torque converter replacement.

HOW TO CLAIM: Contact your GM dealer with your VIN. Multiple TSBs address this (PIP5353, PIP5555, etc.). If the fluid exchange does not resolve the shudder, the torque converter should be replaced under warranty.

Coverage eligibility depends on your VIN, original sale date, and current mileage. Always verify with an authorized dealer or manufacturer customer service — programs may have been updated since this database was compiled.
