2024 Cadillac CT4 Complaint Log

I was driving slowly into my driveway to prepare for turning into my garage. The car rapidly accelerated on it’s own causing me to crash into the garage door next to the one I intended to park in. I have video from my security system.

My car doesn't advise when other car is closed

The contact owns a 2024 Cadillac CT4. The contact stated that while driving at an undisclosed speed, the low oil pressure warning light illuminated. The vehicle was taken to a local dealer where the rear main seal of the engine was replaced. The contact stated that after the replacement of the rear main seal, while driving at an undisclosed speed, there were abnormally loud sounds coming from the front end of the vehicle, near the engine compartment. The vehicle was taken to the local dealer again where unknown parts were found loosened in the engine from the previous repair. The vehicle was repaired; however, the contact stated that several days later, while driving, the vehicle lost braking functionality. The contact was able to safely drive the vehicle back to the residence. The vehicle was then towed back to the local dealer however, the cause of the failure could not be determined. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 5,200. The VIN was not available.

Manual transmission: Shift from 1st to 2nd can be difficult at times and can only experience partial engagement of 2nd gear causing grinding and/or popping out of gear when releasing the clutch pedal along with loss of thrust.

In November 2023 I purchased this vehicle. The dealership was made aware of the ripples within a few days of driving the vehicle. The windshield was defective and had to be replaced. The staff at the dealership did see the ripples on the windshield and agreed to replace the windshield. On December 14, 2023, the dealership replaced the original windshield even though they had the windshield since November 22, 2023. Within a few days of driving the vehicle, I noticed it also has ripples on the 2nd windshield. I have been to the dealership two times, and no one can see ripples. I have taken the vehicle to an automotive glass company who confirmed the ripples in the windshield. On February 5, 2024, I took the vehicle to a different dealership. The appointment was scheduled by a General Motors representative. The staff at the second dealership cannot see anything and took pictures to send to General Motors. The ripples in the windshield are distracting when driving in the daytime and nighttime.
