Sep 28, 2026Fuel/propulsion system
While driving my 2023 Cadillac CT5-V Blackwing in an active traffic lane, the vehicle experienced a sudden and complete loss of propulsion. I was unable to maintain movement with traffic, and the vehicle became disabled in the roadway. The failure occurred without sufficient warning for me to safely remove the vehicle from active traffic. This created a serious safety hazard because the sudden loss of propulsion exposed me and other motorists to the risk of a rear-end or other collision. This incident is particularly concerning because the vehicle has experienced multiple catastrophic engine failures. The vehicle has experienced four engine failures and is currently at an authorized…

The valve body in the ten speed transmission failed while driving. The transmission did a rough shift and a message popped up on the display saying that power has been reduced along with the check engine light illuminating. The transmission reduced usable gears to prevent damage. I was a hazard on the road way due to not being able to get up to the posted speed limit. The car is at Harvey Cadillac (the dealership I purchased the car from) and I have been told GM is going to replace the transmission under warranty.

I purchased a 2023 Cadillac CT5 from a Cadillac dealership in Cleveland, Ohio on June 24th, 2025 with slightly under 18K miles. On July 30th, I took the car to a local Cadillac dealer due to on a few occasions, while driving down the highway, the car went into "decreased acceleration, drive with care". The service department said the Cadillac had over 90k recalls for the transmission body valve and the backlog for the part was significant, in some cases I read over a year. I hadn't even made one payment yet, and now it's in the shop for who knows how long. Shouldn't the consumer be protected? I was not made aware of any recalls, and the dealership is denying any wrong doing since the carfax…

At 22,000 miles, driving along at approximately 40mph, vehicle felt like it surged - check engine light went on and message of "limited acceleration - drive with care" appeared. Key cycled the car, CEL and message remained. Car would then not drive higher than 3rd or 4th gear and at limited speed as I tried to get it home. Once I pulled into my driveway message appeared "Service Transmission Now - Unable to Shift Soon." Car would then not move when shifted into any gear, including reverse. Had vehicle towed to dealer where they found the transmission valve body needed to be replaced. There are no available parts anywhere in the country and was told this could be a long wait for repair. Upon…
