CADILLAC Complaints

Car suddenly stopped while driving and would not start and stalled. Tried to restart multiple times with failed to restart. Car cranked but did not start after multiple attempts. There were no warning signs or indication before stall. Luckily, incident happened in parking lot way out from it. Traffic behind had to steer to other lane to maneuver. Stalling on public road or freeway could’ve been a safety concern for occupants and others. Dealer diagnosed the issue as faulty fuel pump driver module and replaced the part. Issued was fixed under vehicle manufacturer warranty.

The contact owns a 2019 Cadillac XT5. The contact stated that while leaving the driveway, there was an abnormal sound coming from the vehicle. The contact stated that while driving at 65 MPH, there was an abnormally loud squeaking sound coming from the vehicle. The check engine warning light was illuminated. The contact thought that the catalytic converter had been stolen. The vehicle was taken to an independent mechanic who determined that the catalytic converter was severed at the connection point and cracked, and removed. The contact stated that coils were damaged, and the thermostat housing was cracked. The vehicle was repaired, but the failure recurred. The local dealer was contacted, who determined that the catalytic converter had been replaced, but the failure persisted. The dealer informed the contact that the parts were on backorder. The manufacturer was not contacted. The failure mileage was approximately 100,000. The VIN was not available.

During oil change Cadillac mechanic noted camshaft oil seal leak. Video was provided. Mileage on car is 51,534 at that time. I feel that this is too premature and repair requires pulling the engine. Very expensive. Quote was $4,597

The contact owns a 2014 Cadillac CTS. The contact was informed of NHTSA Campaign Number: 20V038000 (Power Train). The vehicle was taken to a dealer; however, the vehicle was not diagnosed or repaired. The dealer informed the contact that the recall remedy could not be performed because the transmission and axle had failed and required repair and replacement. The vehicle was not repaired. The manufacturer was made aware of the issue. The failure mileage was unknown.

We got the message that our steering may be impacted and then our temperature gauge wasn’t working nor the stop/start feature. Trip to service dealer resulted in a $1,186.14 repair for the replacement of the thermostat. This car only has 37,269 miles. We were told by service tech this is a common issue in GM models and this year of car. This was a financial hardship on us and our well maintained, and rarely used, vehicle. How can GM know this is an issue and not offer remedy thru a recall?

I purchased this vehicle on October 20, 2025. I took it to the Cadillac dealership and was told a list of over 20 issues involving the vehicle. The tires have holes in them. The suspension is at Rick of failing, wiring and components are missing. The night vision camera and radars on the vehicle and not functioning. I was told this vehicle should not have been on a lot to be sold.

The vehicle experiences a Shift-to-Park malfunction in which it does not consistently recognize that it is in Park, despite being physically shifted into the Park position. When this occurs, the vehicle may fail to shut down properly or behaves as if it is not securely in Park. The condition is reproducible and occurs during normal use. The issue first appeared in approximately mid-2024 at an estimated mileage of 80,000–85,000 miles and continues to occur. No crash or collision has occurred. However, the defect involves core powertrain and electrical systems and presents safety concerns related to reliable gear recognition and vehicle shutdown. The vehicle remains available for inspection upon request.

The check engine light has been coming on intermittently and the engine has felt rough operating. On December 23, 2025, despite the absence of an illuminated "Check Engine Light", I was driving the vehicle when it suddenly lost power/acceleration in the middle of a busy street, which caused me to nearly get into an accident. I brought the vehicle into the Dealership on 12/29/25, and is still there as of 1/7/26. The Dealership has hooked my car up to the scanner, which found code P0300, and they indicated that it's showing a history of misfires across all cylinders. The Dealership has said that they cannot fix the car because they cannot get the Engine Light to illuminate and because as of 1/7/26, my VIN is not included in part of the widespread Engine recall. My vehicle poses an extreme safety risk to drive, and I do not feel comfortable driving it, knowing that the Engine is misfiring and could lose acceleration or power at any moment and without warning.

The contact owns a 2021 Cadillac XT6. The contact stated that while sitting inside the vehicle, the vehicle felt unbalanced. Upon inspection, the contact noticed that the H-pipe was leaning more to the right side. The H-pipe was not centered as intended. The vehicle was not taken to the dealer or an independent mechanic. The vehicle was not repaired. The contact stated that in the past, while the vehicle was serviced, no one had noticed that the H-pipe was off-center. The manufacturer was not notified of the failure. The failure mileage was approximately 37,000.

Telematics Controller has gone out. Took 2 weeks to get vehicle into dealership. After diagnosis we are told there is no availability on the part and no backorder or visibility as to when it will be available. Functionality of vehicle, value and user safety has been effected as safety and convenience features originally on the vehicle no longer function and cause distraction.
