2015 Cadillac ATS Complaints

ENGINE,FUEL/PROPULSION SYSTEM — Filed 04/04/2026

Fuel and/or combustion problem leading to excessive emissions at unpredictable times. I mean so much smoke suddenly comes out that the driver behind can't see, and it seems the car may be on fire.

STEERING,ELECTRICAL SYSTEM — Filed 03/10/2025

I bought my car from a dealership. Owned it for 2yrs 2mo. 107k miles First issue came up after 3-4 months. Faulty power steering. Took it to service at a dealership they said I would need my wire harness assembly replaced as well as a steering gear. Problem still persists. Also one of the mechanics there showed me that the previous owner glued harness connector components together which is why I started seeing issues that weren't there before. Now today three new warning/service lights: abs, brake warning and traction control lights. I think it is the battery but I haven't tested it. Someone online with the same issue said he had to replace the electronic brake control module. So this issue has not been diagnosed. As a result of the traction control malfunctioning suddenly I spun out on the highway in slippery conditions but did not collide with anything. Both issues are available for inspection. More information can be found on the quote in the attatchment.

UNKNOWN OR OTHER — Filed 03/06/2025

The white pearl paint is chippng off everywhere. It started aat the drivers door directly under the rear view mirror. The underside of the trunk deck lid is completely paint free at this point. There are bubbles eroding on the drivers side rear fender area. When a paint meter was used to check the thickneess of the paint - it was disagnosed at a "1'", WHICH IS THE THINNEST possible number on the paint meter. I would like to demand that these parts of my PRISTINE car be repainted at no cost to myself.

EXTERIOR LIGHTING — Filed 09/15/2023

I received a warning message : Right low beam light failure. I took the car to the deal and was quoted a price of $900.00 to replace the light. This is a safety issue and should not cost that much to replace a light. Searching the web, that is an average price for this type of repair???
