CADILLAC Complaints

On March 19, 2026 around 830AM EST, the vehicle turned off while I was driving around ~40mph. I lost all power while on a busy street and I was unable to move the car to the side of the road. The car would not shift into drive or neutral, and therefore remained in the middle of the road until a tow truck had to flatbed it to the Cadillac dealership. The L87 recall on this vehicle was performed in August 2025, however the Cadillac dealership said there were no issues found with the L87 recall. The symptoms of today's issue - vehicle turning off while driving and does not start back up, is similar to other reports of this L87 recall and demonstrates that this recall was not accurately performed and/or remedied during the service.

The contact owns a 2018 Cadillac XT5. The vehicle was recently purchased, and while driving at an undisclosed speed, the vehicle failed to accelerate as intended while depressing the accelerator pedal. In addition, the vehicle failed to accelerate above 5 MPH with several unknown warning lights illuminated. The dealer was notified and sent a mobile mechanic to the residence to diagnose the vehicle; however, no cause for the failure was found. The vehicle was towed to the dealer, and it was diagnosed that the emission starter module had failed. The dealer reprogrammed the emission starter module. The contact stated that a week after the repairs were performed, while driving at an undisclosed speed, the vehicle sputtered, and the failure persisted. Several unknown warning lights were illuminated. The dealer was notified of the failure. The vehicle was not inspected or diagnosed due to the cost. The contact stated that the failure persisted, and the vehicle failed to start. The vehicle was no longer able to be started. The contact stated that the vehicle was repossessed but was recovered. The vehicle was towed to the residence and had not been driven since. The manufacturer was not notified of the failure. The failure mileage was approximately 2,000.

The engine in my 2015 Cadillac Escalade failed unexpectedly at approximately 53,000 miles. Immediately prior to the failure, the engine developed a noticeable knocking noise, indicating a potential internal issue. While attempting to park in a public parking garage, the vehicle suddenly lost power and the engine shut down without any warning lights or alerts. This created a hazardous situation in a confined area with other vehicles and pedestrians, as I was unable to properly control or maneuver the vehicle. The sudden loss of power and complete engine shutdown significantly increased the risk of a collision or injury. The engine would not restart after the failure, leaving the vehicle disabled in the garage. Due to the confined space, the vehicle had to be removed using specialized towing equipment. The vehicle has been dealer-maintained since purchase, and I am the original owner. There were no prior major engine issues before this incident. The vehicle was towed to a dealership, where it was confirmed that the engine had seized and failed internally. I was quoted approximately $20,000 for a rebuilt engine replacement. This type of catastrophic engine failure at relatively low mileage, without warning, presents a serious safety concern.

Engine has been making a knocking sound and shaking and vibrating very loud loudly. The engine light has been on as well as the traction light and it is acts like it’s going to stall every time I turn on the engine. Because of safety concerns, especially on the very busy highway, where I do a lot of driving, I have been afraid to drive the car. Sewell Cadillac is aware of the engine problem and they informed me I need a $10,000 engine replacement! My 2020 engine falls outside of the current recall by one year. I feel as if GMC should be responsible for this unbelievable and totally unexpected problem! I have several friends who are experiencing the same issues with their GMC with the same year and comparable mileage.

I took my car is for service at the Cadillac dealership and they stated there was an oil leak from the camshaft carrier. When I asked more questions they stated it was a fairly common problem with the XT4 and a few other models where there was a faulty seal at the "T-joint" (cam carrier T-joint). My car is no longer under warranty, but had under 26000 miles at the time. There were no warnings or symptoms. I would not have not if the dealer had not told me. The cost was estimated at $3254.45. If this is a common problem, why isn't there a recall?

The contact owns a 2019 Cadillac Escalade ESV. The contact stated while driving approximately 65 MPH, the rear wheels locked up and the vehicle stopped moving. There was no warning light illuminated. The vehicle was towed to the residence, and the vehicle was not driven. The contact had not taken the vehicle to a local dealer or independent mechanic. The vehicle was not diagnosed or repaired. The contact researched online and related the failure to NHTSA Campaign Number: 26V085000 (Power Train); however, the VIN was not included. The manufacturer was informed of the failure. The failure mileage was approximately 127,000.

I had to replace the thermostat which is a well known, documented defect/issue for this vehicle/Cadillac. I would like reimbursement from Cadillac.

The engine suffered catastrophic failure, piston number six 6and connecting rod broke in pieces and made a hole on the block. This is a L 87 engine 6.2 L.

I SCHEDULED SERVICE A SERVICE APPOINTMENT WITH RICK HENDRICK CHEVROLET IN NAPLES, FL. AFTER LEAVING THE VEHICLE AS SCHEDULED THE SERVICE MANAGER REFUSED TO PERFORM THE SAFETY COVERED RECALLS AND STATED DUE TO THE ISSUE OF THE VEHICLE HAVING A BRANDED TITLE.

In early February, 2026, a check engine light produced code P1098, engine coolant control valve position sensor performance. Code caused the cooling fans to run continuously when the engine reached a certain temperature and the vehicle had reduced acceleration, which posed a safety hazard when driving the vehicle due to prolongated times to get to the posted speed limit and posed a hazard to other drivers because of reduced acceleration. The vehicle was inspected by Jerry Seiner Dealerships on North Salt Lake, Utah and the check engine light code of P1098 was confirmed. I reviewed General Motors bulletins and found that a special coverage N252508341 which covered LM2 Coolant Control Valve Replacement, dated September 16, 2025. The special coverage applies to Cadillac Escalade model year 2021 to 2023. When I asked the dealership about this coverage, I was informed that the coverage did not apply to my vehicle as the bulletin was VIN specific. I called Cadillac and opened a case with Cadillac as I found it unreasonable that General Motors / Cadillac know there is an issue with coolant control valves, yet they refused to cover the cost of repairs for my vehicle because of the VIN was not part of the special coverage N252508341. I paid for the dealership to replace the coolant control valve as the vehicle was not safe to drive due to the reduced acceleration. My complaint is that General Motor / Cadillac knows there is an issue with the coolant control valves for my vehicle model year, yet they refused the coverage for my vehicle due to the VIN. General Motors offered to cover $216.06. I paid $1,387.40 + 3% credit card transaction fee for the repair, this repair would have been free under the special coverage bulletin. General Motors should reimburse me for the expense of this repair as they know there is an issue with coolant control valves.
