2021 Cadillac CT5: problems, recalls and reliability

“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.”Owner report · Air Bags · Jul 2025

“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.”Owner report · Steering · Jun 2025

“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 .

“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.”Owner report · Structure · Jan 2025
