Most Recent Complaints
The electronic exterior door handle on my CT5 has failed and raises a concern of what if there was an accident and nobody was able to open the door if I was unconscious. I believe that having a key access is not enough and there should be a mechanical exterior door handle instead of an electronic handle that fails and is costly to repair.
While slowing down vehicle felt as if it was put into park momentarily, which cause car to slide on ice. After reading the recall, I am certain that the transmission failed. Car was towed to Ray Skillman cheverolet on south post road in Indianapolis, to which they already ran the vin and agreed to perform the recall. After they realized it was a more serious problem than software, they refused to work on the vehicle. So they worked on it long enough to find out they would have to cover it, then denied that they would do any work. They stated that the title is branded. The BMV has no brands listed on title. The service guy Ryan laughed at me today when I stated that it was dangerous, and told me good luck getting some one to help if I filed a complaint. Regardless they won’t touch the car
While key FOB is operational, next to car door and under moderate temperature conditions, the exterior door handle(s) wont open the car door. The doors freeze, remain latched in place from the outside. The interior door handle on the same door remains operational. This makes it difficult to get into the vehicle to remove people from inside the car should dangerous conditions be present while they are unable to operate the interior handle themselves and/or its difficult to enter the vehicle for safety should dangerous conditions be present outside the vehicle. The doors are jammed, we cant get to you!! There are reports of this happening to all four doors. The dealership says the exterior door handle must be replaced for the door to open from the outside again and it is uncertain if the replacement handle has the defect corrected or not. The latch freeze could occur again, anytime unless the replacement is improved. My vehicle had only 8500 miles on it and the exterior handle failed on the front drivers side. How many times will this condition repeat itself without warning during the lifetime of the car. CadillacForum has discussion on the matter including how some with the problem are disassembling the part and “repairing” the handle defect from the inside. This unnecessary risk could develop into an event that contributed to injuries. A reliable part must be installed asap though many cannot afford the $480 expense to replace it at the dealership. I had a 2000 Cadillac CTS for 20 years and didn’t have a problem with doors locking up from the outside - door handles not responding to efforts to open the door with a correct and operational key fob present. Link to discussion on failing door handles on Cadillacs below [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
The contact owns a 2020 Cadillac CT5. The contact stated that the check engine warning light was illuminated. The contact had noticed an oil leak and that the battery charge was abnormally low. The contact received an alert from OnStar pertaining to the critically low battery. Additionally, the contact noticed that there was an abnormal squishing sound coming from the dashboard, and the contact believed that the sound was coming from an animal that had intruded into the vehicle. The local dealer was contacted, but the vehicle was not diagnosed or repaired. The vehicle was taken to a tire center where all four TPMS sensors were replaced. The failure mileage was approximately 75,000.
