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.

ELECTRICAL SYSTEM

The exterior door handle latch release switch fails to open the door. This issue happened to all 4 exterior doors. The problem starts with intermittently, then progresses to complete failure. Once it fails, the entire door handle needs to be replaced. If all 4 doors fail, the only way to access the car is with the Emergency Key or if you activated the Remote Window Down. This only works if you have access to the key. If you left your keys in the car, the car would lock (even if running) then your only option is to fiddle with the switch in hopes of activating it or crawl through the trunk (if you're small enough). If an infant or a pet is in the car, then that could lead to problems. Also if you pass out and emergency responders came out, they would have to break the window or pry the door open to gain access, which could pose a life or death situation. This is a well documented issue with this car per the Cadillac Forums. I replaced both the front door handle assemblies to repair the main access to the car. The rear handles are still inoperable. During inspection of the Handle Electronic assembly, it appears that the switch isn't fully seated against the circuit card, which causes the solder connection on the circuit card to fail.

FUEL/PROPULSION SYSTEM

Car interior smelled like gas when the car is started. but seemed to clear while driving. Found that the Fuel hose between the pipe and the fuel intake was leaking when the car initially started. You could smell the odor when the hood was raised. This is the Pipe and Hose that you need the Fuel clamp removal tool for that is located in the rear center of the engine just in front of the firewall. The leak was about 3 inches from then end where it connected to the engine. Currently I have a temporary repair on it (Fuel coupling) where the hole was. Note, This car is out of warranty. It has been to the dealership (Step One Cadillac in Ft. Walton Beach, FL) for other recalls, but the dealership did not mention any issues.

STRUCTURE:BODY

Beginning of 2025 my drivers side door handle would not open from the outside of the car only the inside . I took it to a certified Cadillac dealer which they had to replace the door handle . Now July 10, 2025 my front passenger side is doing the same thing and I will not have to take my car in to see if they can fix it or it this too will need to be replaced. This causes a hazard of emergency no one would be able to open the door from outside of the vehicle .

AIR BAGS

My 2025 Cadillac CT5 was stationary at a red light behind a red truck when a black truck traveling in the opposite direction struck the truck head-on. The red truck was pushed backward into the front of my CT5 with enough force to cause major front-end damage. Despite this, no airbags deployed. I believe the airbag system failed to detect or respond to a valid crash condition and there is a larger safety concern that needs to be reviewed. Police report completed. Insurance has not inspected vehicles yet but it is available to be inspected.

EXTERIOR LIGHTING

aste): The vehicle has a serious pulling issue while driving, which was not corrected with alignment and poses a safety risk. Additionally, the windshield was scratched by faulty wiper blades that impaired visibility — the dealer later reimbursed me. Lastly, the driver-side running light was not functioning, which creates a hazard and may violate federal lighting safety standards.

VISIBILITY/WIPER

aste): The vehicle has a serious pulling issue while driving, which was not corrected with alignment and poses a safety risk. Additionally, the windshield was scratched by faulty wiper blades that impaired visibility — the dealer later reimbursed me. Lastly, the driver-side running light was not functioning, which creates a hazard and may violate federal lighting safety standards.

STRUCTURE:BODY

Currently my passenger door and my rear driver side door do not open from the outside. I already had to have my driver side door handle replaced for the same issue, now three out of four of my handles have failed. If an accident were to occur no one would be able to access the passenger or the rear driver passenger from the outside because the doors do not open. Since I can not open the door from the outside I had to remove the child lock from the rear door so my child can exit the vehicle.
