CADILLAC Complaints

On 1/13/2026 while driving on the 91 freeway near Long Beach California we heard a load Pop sound and then felt some air and outside notice in the car . Pulled over shortly and saw a large hole in the rear sun window with cracked glass everywhere. . Made an appointment at Penske Cadillac and a few days later they are checking to see if it’s covered under warranty. Also filled a claim with AAA . There was absolutely no rock or debris involved.

The engine valvetrain is suspected, specifically an AFM (Active Fuel Management) lifter or related lifter/oil control component. The vehicle and affected components are intact and available for inspection upon request. An unresolved internal engine malfunction presents a risk of sudden power loss, engine damage, or stalling while driving, which could increase the risk of a collision, particularly at highway speeds or in traffic. The issue has been reproduced consistently by the vehicle owner. Diagnostic work has been performed by independent parties, including inspection of the exhaust system, belts, and valvetrain components. Further confirmation by a dealer has not yet occurred. The vehicle has not yet been inspected by the manufacturer, police, or insurance representatives. Independent mechanical inspection and repairs have been performed. No warning lamps or messages were displayed. Symptoms include a delayed chirping/ticking noise beginning approximately 20–30 seconds after engine startup, which is repeatable and changes with engine load and cylinder deactivation behavior.

Front driver side door unable to open from the outside. Faulty door handle pad. Initially randomly wouldn’t work, would have to press the pressure pad multiple times or press on specific part of the pad. Eventually, stopped working all together. It’s a safety issue if unable to open the door during an emergency. Pretty common issue on Cadillac CT5s regardless of trim. Affects all 4 doors, just happen to be the driver side is the most used.

The passive door locks on the handles to the car do not work. The electronic sensor to unlock the car does not work due to misalignment of the pin that is supposed to press the key. This is a widely known issue on 2020-2021 Cadillac ct5 vehicles. This eventually results in total lockout of the vehicle. I currently have three doors that do not unlock. Please see a link to the issue I reported on Cadillacs form website as well https://www.cadillacforums.com/threads/door-handle-issues.1141023/?nested_view=1#post-18436706
