Mercedes-Benz Emissions Warranty Settlement -- File a Claim by May 15, 2026
By eosguide team · Last updated April 28, 2026
Mercedes-Benz is settling a class action over emissions warranty coverage for 14 vehicle parts. Owners in 17 states may claim 50% repair reimbursement by May 15, 2026. Mercedes didn't mention 14 specific parts should have been covered under warranty -- now they'll give you half back for the repairs you already paid for.
What happened
Class period: Model year 2015 to present (coverage start date varies by state). Repairs or diagnoses must have occurred after the vehicle's 4-year/50,000-mile warranty expired and before the 7-year/70,000-mile warranty limit.
- Plaintiff sued Mercedes-Benz USA, LLC (MBUSA) alleging that 14 specific vehicle parts in Mercedes-Benz cars should have been classified as "high-priced" emissions warranty parts (HPP) under California law -- meaning they should have been covered for 7 years or 70,000 miles, whichever comes first
- Because MBUSA allegedly did not classify these parts as HPP parts, owners and lessees in California and other Section 177 states were not notified of this extended warranty coverage and paid out of pocket for repairs and diagnoses that should have been covered
- The 14 subject parts include components such as the Power Train Control Unit, Coolant Thermostat, Charcoal Canister, Accelerator Pedal, Crankcase Ventilation System, and ESP Electronic Stability Program Control Unit, among others
- MBUSA denies all wrongdoing and denies that the parts were improperly classified
- The settlement covers owners and lessees of model year 2015 and newer Mercedes-Benz vehicles registered in California or the other 16 Section 177 states that adopted California's emissions warranty requirements
What you can get
50% reimbursement for out-of-pocket repair costs and 100% reimbursement for standalone diagnosis costs for covered parts; plus ongoing warranty coverage for those parts going forward.
