2022 Cadillac CT4 Owner Complaints

While driving at higher speeds the multiple CT4 vehicles that I have driven share steering issues. While driving straight, there are no issues. If following gentle bends in the highway to the RIGHT, randomly the vehicles will increase the force required to maintain the current ground track. This causes the vehicle to slightly pull away from the desired track to the left. It does NOT occur when steering to the left, only to the right. It feels as if the steering enters a different type of steering mode and eases the required steering wheel pressure when the vehicle returns to straight driving. The fact that this steering is sour is randomly timed, only occurs in one direction leads me to believe that it irks an engineering problem. I have found this issue to present itself on the CT4 and CT5. I have personally driven the vehicles as well as confirmed the issue with sources online. I do not feel that this issues constitutes a safe steering feedback.

While driving in normal street conditions, the dashboard lit up and all the lights came on. Traction control, stability control, check engine light, tire pressure, brake, ABS all lit up. The digital dash showed two errors: 1. Forward Collision System Unavailable and 2. Steering assist is reduced, drive with care. I noticed that steering became much more difficult and braking was extremely difficult. When coasting to a park, my car would not engage the e-brake unless I shut the car down at first and then re-started it. This is the second time this has happened to me, the first time was 4 months ago and the Cadillac dealership already tried to fix the problem by replacing a brake control module. Clearly they did not fix it and now I do not feel safe in the vehicle. The problem is not easily reproducible as it comes on randomly while driving (I was literally cruising in 5th gear). My car is a manual transmission if that makes a difference, so the e-brake is pretty vital. Uploaded are pictures from 4 months ago when the problem first happened and I was stopped at my house. The last picture was from yesterday while I was driving and the issue re-occurred. I have dropped off my car today at the dealership for them to look at again.

A few days ago while driving (45mph), my 22' 4BW dash lit up like hell and I lost power steering, brakes, went into limp mode. Restarted the vehicle, all was well. I did almost take out the Mini Cooper in front of me, with a 'Baby on Board' sticker. Don't even want to think about that. I have a service appointment scheduled for next week and I'm not driving the vehicle until then. Please review the following thread on the Blackwing forums where over 7 different people experience the same issue within 7 days of each other. https://www.cadillacvnet.com/forums/threads/ct4bws-turning-off-safety-risk.3928/#post-75520 Dealers are not taking responsibility for this issue and we are afraid to drive our cars.

The problem first arose in June 2023. I was driving and suddenly, all the dashboard lights went on and the brakes stopped working. There was no pressure on the pedal. I was able to roll to a stop without incident. I turned the car off and back on again and the brakes worked but the check engine light was still on. I was able to limp the mile back to my house. After almost 6 weeks at the dealer, I was told they replaced a brake module and the car was fine. On [XXX], it happened again. It was towed to the dealer and I refused to drive it again. The car had about 2400 miles on it. They took it back, although claiming nothing was wrong, and I bought the CT4V Blackwing 2023 VIN [XXX] . On [XXX], it happened in the new car (500 miles on it). The dashboard lit up, the brakes wouldn't work, although this time instead of no pressure on the pedal, it was hard as a rock. After turning it on and off again, the brakes worked but the speed was restricted and other things in the car did not seem to be working correctly. The check engine light was also on. The dealership towed it. They told me they could not recreate the problem. Weeks later, I was told that an engineer from GM was looking at it. I received a call from some customer support department person who eventually told me that there was nothing wrong with the car, that the brake failure was a result of the Allstate Milewise device that was plugged in and they would not do anything for me. My husband has a Milewise in his Chevy truck with no issues. I found a forum online discussing this problem which has apparently happened to numerous people in CT4V and Blackwings. I also spoke to Allstate which does not have any reported problems with the device. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The check engine and the crash warning lights were illuminated. The contact coasted to the side of the road while depressing the brake pedal with an excessive amount of force. The vehicle was stopped by bumping on a nearby curb. Once the vehicle was stopped, the contact turned off and restarted the vehicle and was able to regain power steering and power brakes functionality. The check engine warning light remained illuminated. The failure had occurred twice. The vehicle was taken to the dealer where it was diagnosed that the vehicle was showing 24 failed Communication codes; however, the exact cause of failure was unknown.
