The problem first arose in June 2023 with a different car, 2022 CT4V VIN [XXX] .  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.  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)

CADILLAC CT4 2023 VEHICLE SPEED CONTROL

Early morning starts, backing out of my garages which has a slight angle to is and then putting the car in drive and accelerating at a low speed when car reaches 10 miles per hour the engine races and the transmission hesitates.  This only happens on the at the start of the day. Doesn't happen again until the next day.  It does this 90% of the time. Additionally, throughout the day if you let up on the gas and coast then accelerate it take a few second for the transmission to reengage.

The vehicle shut off while driving on the feeder of the highway. Vehicle was no longer responsive and had to be towed to Central Cadillac of Houston; where later it was determined that the vehicle needed a new engine. The Vehicle is a 2023 with less than 5,000 miles on it. Currently General Motors/Cadillac is not acknowledging that a buy back is needed for the vehicle, even though it meets requirements for the Texas Lemon Law.
