What 2016 Cadillac XTS owners say
Electrical system
Hazard lights go on automatically while driving. This creates a huge safety issue, especially when driving in high traffic areas as other drivers may mistake Hazard Lights as turn signals. I brought my vehicle in to a Cadillac dealership in December of 2020 to replace the Hazard Light switch. They replaced it with OEM parts, and the issue started happening again in April of 2022. The Hazard Lights will also engage when the vehicle is not running, so this discharges the battery to the point you need to buy a new one. Cadillac needs provide customers with safer Hazard Switches. This is the second time within 2.5 years the Hazard Lights need to be replaced.
Stabilitrak light comes on that also causes the engine light to come on. The vehicle self-accelerate while in park and did again when in drive. Can not tell you how fast the Rpm accelerated due to panic that the vehicle was self-accelerating but it didn't last long. Really quick and it went back to normal idling. Vehicle is scheduled for inspection today 1/20/25 at Classic Cadillac Atlanta. No warnings were given, lights(stabiltrak) just came on. Also the suspension rides very low. It feels like there are no shocks either front or rear.

20-inch aluminum alloys wheels are all bent. I purchased this vehicle from a dealer near Lansing, Michigan. Upon test driving there were 2 wheels low on air. The dealer inspected the wheels and assured me they were fine. Once I got home I took the car to a local dealer who confirmed that all 4 rims were bent. This was also confirmed by the local tire shop. 4 rims for the vehicle were almost $[redacted], which also had a 3-4 month back order. The dealer and tire shop confirmed that bent 20" rims are a major problem for GM and aftermarket wheels were the only option if I did not want to wait months. I contacted the previous owner of the vehicle (they left their registration under the car seat) and they confirmed they had the same issue. The previous owner was told It was tires, and after purchasing 4 new tires (The same model as came from the factory) the problem persisted. …
