Mileage at failure isn’t a structured field in NHTSA complaint data, so we don’t chart it. Some owners mention it in their reports below.
Top problems in owners’ words
Verbatim from NHTSA complaints, newest first
Steering
6 reports1 crash
“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.”
Electrical system
6 reports
“The CUE SYSTEM not totally working, and panel plastic is all spider web looking. I view this as a very bad problem( it won’t go to settings), no radio, can’t set the clock Not sure on all the problems as I can’t get to it to find out.”
Power train
5 reports1 crash
“My rear differential completely stopped on the freeway, not moving and saying over 100 mph and my car was barely rolling I am extremely lucky that I did not get rear ended because I was very close to that happening, a few cars had swerved to not crash. Luckily I was able to push my car to the exit and get off of the freeway to wait for the flatbed to pick me up. It is available to be inspected it’s just parked until I can get it fixed, the part is $1800 and I have not been able to afford it. I had a mechanic come and look at it and I was told what part it is. There was absolutely no warning lights for this issue.”
Exterior lighting
4 reports
“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???”
Air bags
3 reports1 related recall
“The contact owns a 2015 Cadillac. The contact received notification of NHTSA Campaign Number: 26V329000 (Air Bags); however, the part to do the recall repair was unavailable. The dealer was contacted by phone, and the contact was informed that the parts were unavailable to repair the vehicle. The contact stated that the vehicle was unsafe to drive.”
Fuel/propulsion system
2 reports
“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.”
