The contact owns a 2012 Mercedes-Benz SLK350. The contact stated that while driving at an undisclosed speed, a loud noise was heard coming from the rear of the vehicle. The contact stated that as she pulled over and parked the vehicle, the low tire pressure warning light illuminated for the driver's side rear tire. When the contact exited the vehicle, she saw that the rim hub cap had detached from the driver's side rear wheel. The vehicle was then towed to an independent mechanic who removed the tire and sent it to a local dealer. The mechanic at the local dealer made the contact aware of a crack on the side wall. Additionally, the contact stated that the tire was taken to the original place of purchase, and the claims team determined the failure was caused by damage from the rim and advised the contact to call the vehicle manufacturer for assistance. The vehicle was not repaired; however, the spare tire was installed. The manufacturer was made aware of the failure. The approximate failure mileage was 105,000.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2012 Mercedes-benz Slk-class verdict →
