Complaints on fileComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

2 of 245/40HR18XL & 2 of 225/45HR18XL... All 4 tires replaced I purchased a 2023 Mercedes-Benz C300 from Benzel Busch motor car (an authorized Mercedes-Benz dealer) in [XXX] in XXX. Since purchase, this vehicle has had repeated, unresolved defects. The Check Engine warning light has illuminated numurous times, resulting 4 separate towing incidents. Despite multiple warranty repairs, the same issues keep recurring. At only 10,167 miles, one tire required replacement due to abnormal wear. At only 22,780 miles, all 4 tires required full replacement for the same reason. In total 5 tires have been replaced within 22,780 miles, strongly suggesting an underlying vehicle defect (alignment, suspension or steering) rather then normal wear. I paid $1,700 out of picket for the 22,780 miles tire replacement, as tires are not typically covered under warranty. I believe this cost resulted directly from an unresolved vehicle defect, not drive behavior. I filed a formal complaint with Mercedes-Benz USA Customer Assistance Center and received Case No. XXX. I was told reimbursement would not be provided. Desired Resolution: Reimbursement of $1,700 for the tire replacement caused by an unresolved vehicle defect, and a written explanation of how Mercedes-Benz USA will address the recurring mechanical issues. Supporting docyments available: Repair orders, tire receipt, email correspondence. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
