CADILLAC CT5

POWER TRAIN:AUTOMATIC TRANSMISSION

General Motors LLC (GM) is recalling certain 2019-2020 Cadillac CT6, 2020-2021 CT4, CT5, and 2020-2022 Chevrolet Camaro vehicles equipped with a 10-speed transmission. The transmission may become damaged internally and cause the wheels to lock-up.

Risk: Wheel lock-up while driving increases the risk of a crash.

EXTERIOR LIGHTING:LIGHTING CONTROL MODULE:SOFTWARE

General Motors, LLC (GM) is recalling certain 2020-2023 Cadillac CT4 and CT5; 2021-2023 Buick Envision; and 2022-2023 Cadillac Escalade and Escalade ESV, Chevrolet Silverado 1500, Suburban, Tahoe, GMC Sierra 1500, Yukon, and Yukon XL vehicles. The daytime running lights (DRLs) may not deactivate when the headlights are on. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 108, "Lamps, Reflective Devices, and Associated Equipment."

Risk: DRLs that do not deactivate as intended may result in a glare, reducing visibility, and increasing the risk of a crash.

AIR BAGS

General Motors, LLC. (GM) is recalling certain 2020-2022 Cadillac CT4 and CT5 vehicles. The roof rail side-curtain air bags may not have been installed correctly, which could result in an improper air bag deployment during a crash.

Risk: Air bags that do not deploy properly can increase the risk of injury in a crash.

ELECTRICAL SYSTEM:SOFTWARE

General Motors, LLC (GM) is recalling certain 2021 Buick Envision, Cadillac CT4, CT5, Escalade, Escalade ESV, Chevrolet Tahoe, Corvette, Suburban, GMC Yukon, Yukon XL vehicles. The communications gateway module incorrectly processes a loss of communication with the sensing diagnostic module (SDM), causing the air bag malfunction indicator light to inconsistently illuminate.

Risk: The air bag malfunction indicator light may fail to warn the driver of a problem with the air bag, increasing the risk of injury.

POWER TRAIN

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.

ELECTRICAL SYSTEM

CT5 2020 Doors will not unlock.

POWER TRAIN

The contact owns a 2021 Cadillac CT5. The contact stated that while driving approximately 42 MPH – 66 MPH, the vehicle was shaking abnormally. The contact stated that while driving at an undisclosed speed, the vehicle jerked and shuddered while shifting gears. The cause of the failure was not yet determined. The local dealer and manufacturer were notified of the failure. The failure mileage was 48,600.

WHEELS

Two separate issues: One is being sold a vehicle with a Certified vehicle at 12K miles with a defective, faulty transmission which is a manufacturer defect from General Motors. 10-speed automatic transmission 10L90 model. Misrepresentation of a product. False advertisement of a product. Failure to disclose. Gross negligence. Unethical & Illegal business practices. Dealer & manufacturer fraud. Second issue: When Valve body was replaced on the vehicle, the service manager of the dealership test drove the vehicle with me in the passenger seat on the highway. The vehicle was still not shifting or accelerating correctly even after the valve body replacement. The vehicle began to shake, jerk and rumble on the test drive. The vehicle drove worse. The service manager and I took the vehicle back to the dealership and he found that two of the wheels, on the passenger side, are now bent. That is how the bent wheels were discovered. Not from inspection. Previous multipoint inspection and diagnosis shows the wheels were not bent before I brought the car into the dealership for mechanical work. I can attest to the fact that my wheels were not bent before service and this obvious shaking of the car was not previously existent. The dealership denies liability for this issue and is now refusing to replace the wheels after I have offered to pay. Dealership service manager told me it was safe to drive the vehicle with two bent wheels and I strongly disagree with that statement and so has my insurance company. It is very questionable as to why the service manager would make such a statement. The dealership told me to call other GM dealerships to have the wheels replaced. They refused to do the work as well. I am seeking the proper resolution in this situation.

WHEELS

Major safety Concern Faulty valve body and transmission dealership failed to disclose. Service manager drove vehicle with bent wheels. That is how the bent wheels were discovered. Not from inspection. Wheels evidently bent under dealership possession. 2020 Cadillac CT5 Vehicle financed at 12K Miles with certified pre owned, bumper to bumper, and powertrain warranties in February 2024 showed poor driving, shifting, acceleration and abnormal behaviors such as slow and delayed shifting/acceleration, loud shifting, jerking, and strange noises from the vehicle and low power. There were very suspicious mechanical issues wrong with the car in which the dealership told me that there isn’t anything wrong with the car, with the understanding that if anything was ever wrong with the vehicle it has been fixed. I was ensured and promised that the car does not have anything wrong with it and that it goes through inspection and diagnostics, that the vehicle cannot be sold without being tested, fixed of any problems and brought to standard. I brought this to the attention of the salesman, owner, financial advisor, service advisor, service manager. I requested a full buyback and replacement of my 2020 CT5. My dealership let me know that they still want me to pay for the valve body, battery, ambient air temperature sensor and rear parking brake motor. I had to call Cadillac corporate/General Motors to have the valve body covered & rear bumper covered/replaced. I was brought into the dealership office and was told that the buyback and replacement was denied by General Motors even though my car was showing symptoms of a defective valve body ever since I financed the car. These things were being ignored by the dealership service department. Laggy and rough acceleration as well as shifting. Strange vibrations and noises coming from the car. Slow moving and the shifting was very jerky and abnormal. The shifting was also very loud and took long times to shift 1-2, 2-3, 3-4, 4-5 gears.
