CADILLAC Complaints

On November 24, 2025, I discovered that multiple connected and safety-related systems on my 2025 Cadillac Optiq had stopped functioning. We believe a GM over-the-air software update was installed the weekend prior, and the dealer has inferred that the update may have caused the failure. We brought the car into the dealership on November 26th. The car was "fixeed" and we picked it up on December 2nd. Before we were able to leave the lot, the telematic system broke again. The dealership inspected the vehicle and confirmed that the telematics module had failed. We left the vehicle at the dealership,. There were no warning lights, error messages, or other indications before the failure occurred. After the failure, several critical safety and driver-assistance systems became inoperable or severely impaired. These include, but are not limited to: OnStar emergency services Automatic crash notification Steering assistance Cruise and speed control Lane-change and driver-assist systems GPS and navigation functions Bluetooth, Wi-Fi, and vehicle internet connectivity Although the vehicle is technically drivable, the loss of these systems poses a significant safety risk to occupants and others on the road. The vehicle cannot contact emergency services in a collision, cannot send diagnostic data, and lacks essential driver-assistance and navigation capabilities. The dealer has confirmed the problem, but the replacement telematics module is currently backordered with no clear timeline, and they stated the delay could last weeks or longer. Because the failure appears to have been caused by a GM-issued OTA update, and because essential safety systems are offline, I am concerned about both the defect itself and the extended inability to repair it due to unavailable parts. UNKNOWN whether GM has conducted a broader inspection or analysis of this update or component, but the failure has been reproduced and confirmed by the dealer’s service department.

My headlights have deteriorated to the point that the vehicle can’t be driven at night. GM/Cadillac acknowledged this as a problem with this particular model. I sent an email to the Cadillac CEO, Rory Harvey. I received a call from an executive assistant stating that this issue was addressed prior to my report. I stated I could not use the vehicle at night due to safety issues. Her response was to offer me a discount on a new purchase. My vehicle now has a significant safety issue. The Cadillac dealer quoted my a price of $2,600 to replace the headlights.

We took the vehicle in for the recall inspection. They pass it and changed the oil. Weeks later, as I was driving home (was on holiday vacation in another state), the engine failed immediately. I was able to get it to the side of the road but the engine would not properly run. Had to call the tow truck and hauled back to the dealership near my home of record.

The contact owns a 2019 Cadillac Escalade. The contact stated that there was an abnormal whining sound coming from the engine with the check engine warning light illuminated on the instrument panel. The vehicle was taken to dealer; however, the dealer was unable to duplicate a failure. Recently, the contact stated that the check engine warning light illuminated on the instrument panel. The manufacturer was not notified of the failure. The vehicle was not diagnosed or repaired. The failure mileage was approximately 48,000.

Incident date: 2025-11-22 Location: I-70 (while taking an exit) Dealership: Jim Coleman Cadillac (vehicle purchased and routinely serviced here) I am reporting a sudden and severe brake system failure that created an immediate risk to vehicle occupants. On 2025-11-22 my wife was driving our Escalade with our two children when, while taking an exit on I-70, she felt the brakes go completely limp and the vehicle would not slow down as expected. The vehicle had been driving normally beforehand; we had made a couple of stops earlier that day. She was able to reduce speed and bring the vehicle to a stop without colliding with another vehicle, but this was only because there was no traffic immediately ahead. A tow was called; the vehicle was first towed to a nearby Cadillac dealer for initial diagnostics and then to Jim Coleman Cadillac where the vehicle was purchased and where all prior services and repairs have been completed. The most recent service/inspection at Jim Coleman had been completed a few weeks prior and no brake concerns or repair recommendations were noted at that time. The last documented brake service prior to this incident was in 2022 at the same dealership. After the incident, when inspected, the dealership service manager reported his findings: "The bolt on the top left front brake caliper walked out, the caliper swung rearward pivoting on the still secured lower bolt and the top piston was expelled from the caliper resulting in rapid loss of brake fluid and a failure of the hydraulic brakes. The reason the bolt came off could have been due to improper machine of the bolt or the caliper bracket that it was screwed into." This failure occurred without warning and represents an extreme safety hazard that could have caused a serious crash. I request that NHTSA review this incident as a potential safety defect, and that it be added to any investigation regarding similar complaints for this model/year.

Cadillac and GM have a know issue in the Escalade for faulty susp3nsion, with their MagRide system, and bad lifters. They use AFM/DOD to reduce the engine down to 4 cylinders and it causes the lifters to get stuck and damage the cam. I am one of thousands to experience these issues. GM need to be held responsible. Why. Are you putting this junk in 100k trucks? Why are we having to foot the bill to get rid of it? My car only has 112,000 miles. This is ridiculous. Please help.

I purchased a car from a used car dealer in Sacramento. Two days later, the lifters went bad. This truck only has 115,000 miles on it. This is a know issue that GM has and they're doing nothing to remedy the issue. They keep putting DOD/AFM in these expensive cars knowing the lifters will fail and cause damage to the cam. They should be responsible for doing a DOD/AFM delete on all trucks that have this issue.

2017 Cadillac Escalade ESV VIN: [XXX] Dealership: Jim Coleman Cadillac, Bethesda, MD I am reporting a brake safety failure involving severe and abnormal brake component wear that created an immediate safety risk with breaks completely failing while driving at high speed on the highway. During normal driving, I discovered that the right front brake assembly had worn down to bare metal. The brake pad friction material was completely gone, resulting in metal-on-metal contact with the rotor. The rotor showed deep scoring and unsafe wear consistent with a possible stuck caliper piston, seized caliper slide pins, or other component malfunction. This failure occurred without warning. The vehicle had been at the dealership for a customary inspection shortly before this issue, and the dealership did not report any brake wear concerns at that time. All brake services and major repairs on this vehicle have always been performed by the same Cadillac dealership. The last documented brake service with chanigng of the breaks involved was completed by the dealership in 2022. This is a critical safety issue that ]caused total brake failure. I am requesting that NHTSA review this defect, as premature brake destruction of this nature may indicate a systemic issue with the brake system, caliper operation, or inspection protocol on this model. The dealership was not sure of the reason why this happened that I was adviced that the bolt was missing and could have come off with vibration which is again a critical safety issue.

Engine failure. Started making a knocking noise on road with my whole family in the car, no lights or warnings on dash and had to pull over and get it towed to nearest dealer. Took a week to get a diagnostic done. Dealer found metal shavings in oil filter believe to be from a connecting rod bearing. Recall 252494000 was done 2,000 miles prior to engine failure. Now dealer must replace engine assembly, engine oil cooler and radiator all due to contamination

Door handle opening mechanism has not been working correctly for over a year. Multiple attempts to open the door will finally work and the door will open. This is a life safety issue that I have taken up with GM multiple times now and they refused to cover the vehicle. When looking online, dozens of other individuals have also complained about this exact issue.
