Several customers of the Cadillac ATS report their vehicles’ wheels failing in multiple ways. The most serious of these failures is structural cracking in the rims, leading to air escaping from the tires and requiring replacement. Several customers are also experiencing cosmetic issues such as the paint peeling and flaking off of the rims. Customers may have claims for defective design.

Cadillac appears to be replacing some of the defective wheels under warranty (but not all), but customers report experiencing the same problem with their replacement wheels. The issue appears to primarily be affecting the 2013, 2014, and 2016 ATS vehicles, as well as 2016 CTS vehicles.

GM’s warranties and terms of sale do not include any class action waivers or mandatory arbitration provisions. Tire and wheel warranties are not sold standard with Cadillac vehicles, and must be purchased as add-ons.

GM faces a similar lawsuit alleging that the wheels of the Chevrolet Corvette crack, bend, and puncture the vehicles’ tires, leading to high replacement costs for drivers. GM’s attempts to dismiss the case were rejected in May 2021, and the case was allowed to proceed.
