CADILLAC Complaints

The rear, third row passenger vent will occasionally put out very hot air. This results in the back seats becoming overheated especially on hot days. This is putting my young children at risk for heat related injuries and possibly death as the front seats remain cooled but the rear compartment heats up substantially. The dealer was unable to reproduce the problem but it occurs at random so reproduction is difficult. No error codes are shown. The problem will resolve once the vehicle is shut off for an extended period of time but will then recur at random putting all rear passengers that are sleeping or too young to complain about the temperature at significant risk.

After driving about 3 hours, the TPMS system displays an error saying the module has failed. This occurs with OEM and aftermarket TPMS sensors. The error clears itself after the vehicle is parked for > 1 hour. The dealer has found no fault in the sensors but would not test the system otherwise. Losing TPMS readings during long drives is unsafe and could lead to an accident or damage to the vehicle if tire damage occurs while the system is malfunctioning.

The contact owns a 2023 Cadillac Lyriq. The contact stated that while reversing and proceeding to make a U-turn, he crashed into a steel guardrail. The automatic braking system did not engage. There was no audible or visual alert or warning provided by the system. There was no injury, police report, airbag deployment, or fire. The vehicle was taken to the local dealer. After twelve days, the vehicle was not diagnosed or repaired. The manufacturer was contacted, who confirmed the vehicle had functioned as designed. The failure mileage was 8,600.

Recall Info: The connecting rod and/or crankshaft engine components may have manufacturing defects that can lead to engine damage and engine failure. If the engine fails during vehicle operation, the vehicle will lose propulsion, increasing the risk of a crash. This information creates anxiety for myself and my wife who already suffers from a medically documented anxiety disorder every day that we drive somewhere. Because of the location of our residence, we have to drive on the highway most of the time for convenience which exaggerates this situation. We have owned/leased GM vehicles our entire lives and particularly Cadillac for the last 24 years. We own this vehicle out right and planned to keep it indefinitely. The fact that there is no immediate remedy for this situation and one day possibly providing a higher viscosity oil, an oil filter replacement and requiring a new oil fill cap is very disappointing and insulting for a vehicle that we had to wait for and then pay over $130,000 for. At this point, thank God there is no incident, I would like to keep it that way and would like to have an immediate resolution of possible switching from our 2023 model to a comparable 2025 and be reassured that it does not have these mechanical defects with no additional costs incurred on my part.

The contact owns a 2023 Cadillac Escalade. The contact received notification of NHTSA Campaign Number: 25V274000 (Engine and Engine Cooling); however, the part to do the recall repair was not yet available. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue. The contact had not experienced a failure.

I was backing up into a parking space in a parking garage. I was about halfway into the spot and was not in danger of hitting any vehicles or objects and my vehicle abruptly (extremely hard) braked.

I was traveling on Stevenson expressway at 55 mph when the fuel pump relay overheated and melted, which burned up the REC (Rear Electrical Electrical Center /fusebox). When the fuse pump relay overheated it shut fuel down going to the fuel pump, which caused the engine to stall. When the engine stalled the car cut off, causing me to loose power steering. Because I was traveling in the middle lane of a three lane expressway at a high rate of speed, the vehicle started deaccelerating and I couldn’t control the vehicle with no power steering, I couldn’t get over to the shoulder. This nearly caused a wreck putting me in harm, because vehicles around me were accelerating at 55 to 70mph. All I could do is put my flashers on. Coast to a stop, and hope no one rear ended me, which nearly occurred.

The contact called on behalf of a dealer who owns a 2023 Cadillac Escalade. The dealer received notification of NHTSA Campaign Number: 25V274000(Engine and Engine Cooling); however, the part to do the recall repair was not yet available. The local dealer was contacted. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was not made aware of the issue. The contact had not experienced a failure. VIN tool confirms parts not available.

Engine started making strange noises and i had to pull over due to it not driving correctly. I was stranded two hours from home. There were no warning lights. I have a video of the noise it was making. Upon getting it towed back to a local mechanic I was told I have the 6.2 GM engine that has been recalled on other vehicles. I found out that the lifters and cam shaft were bad along with the bearings in my engine. I also had to replace the timing chain. My vehicle only has less than 170,000 miles on it. The car was serviced regularly. A local mechanic has already repaired the problem.

I believe the issue involved Super Cruise, forward collision warning, and automatic emergency braking systems. The vehicle is currently at the dealership and available for inspection. It has been there since 6/22/25 because the brakes and rotors are on backorder. While driving on the highway in the middle lane on a Sunday afternoon, I activated adaptive cruise after the vehicle had been parked for over 2 hours. After driving seven miles, the car suddenly jolted to a stop in the middle lane, as if we had been hit. We hadn’t—but cars were forced to swerve around us at highway speeds. If traffic had been heavier, this could have caused a serious crash. I exited safely to a mall parking lot, where the car began smoking from the brake area and gave multiple warnings, including “Reduce braking to avoid overheating.” The car remained parked, but the messages continued. A tow truck driver later said the brakes appeared to have caught fire because of how charred they were. I have video of the smoke and warning messages. This is a major safety concern. No. The issue has not been reproduced due to the parts being unavailable. The car has remained at the dealer since 6/22/25. Not to my knowledge. Only the dealer has had physical access to the vehicle since the incident. Just before the event, I saw a brief message on the screen, possibly “Auto Collision Not Engaged.” I had used Super Cruise previously without issue. No prior warning signs appeared before this failure.
