NHTSA Complaint #11680306 — 2017 MERCEDES-BENZ E300

I am writing to formally lodge a complaint regarding serious and repeated issues with my 2017 Mercedes-Benz E300, purchased and serviced exclusively by authorized Mercedes-Benz dealerships. 1. Repeated OEM Run-Flat Tire Failures Within the past two years, I have been forced to replace nine OEM run-flat tires, including:    •   3 replacements at Mercedes-Benz of Tysons Corner, VA    •   2 replacements at Goodyear Tires, Cattlemen Rd., Sarasota, FL    •   4 additional replacements at certified service centers These failures occur under normal driving conditions, often without visible punctures or road hazards, and at safe speeds. Each tire replacement costs approximately $550, plus towing, diagnostic fees, and rental car costs. The financial and safety burdens are substantial, and this level of tire failure is not normal for any vehicle—particularly a low-mileage, luxury sedan. 2. Electrical/Dashboard Recording Malfunction My dashboard service history fails to record service visits, even when performed at Mercedes-Benz dealerships. This is deeply concerning as it compromises vehicle resale value, warranty tracking, and transparency of maintenance records. Despite multiple visits and attempts by service centers, the issue persists without resolution. 3. Financial Impact and Brand Reputation The total cost of repeated tire replacements and unresolved electrical issues has reached several thousand dollars, despite my vehicle having relatively low mileage and receiving all recommended service at authorized dealers. This experience is completely inconsistent with the quality and reliability promised by the Mercedes-Benz brand. I am requesting the following:    •   Full investigation into the defect rate of OEM run-flat tires on the 2017 E-Class models    •   Immediate inspection and repair of the dashboard/electrical recording issue at no cost to me    •   Reimbursement for tire-related costs and associated expenses incurred due to repeated failures.
