NHTSA Complaint #11504240 — 2008 MERCEDES-BENZ E350

Very strong gas smell both inside and outside of the car with check engine light on. This happened in May of 2022. Could not park the car inside the garage. Contacted MBUSA, they said there is an extended warranty for this vehicle for this problem, advised me to take it to Mercedes dealer. I took the car to the dealer. They checked it out and said it is not covered under the extended warranty because it has passed the mileage ceiling for PZEV which I do not know what PZEV is. I checked The NHTSA website, it says 15 years unlimited miles. I had no other choice but to fix the car at the dealer and pay for the cost. A few months later MBUSA sent me a letter telling me although it has passed the mileage I might be eligible for a refund and wanted me to file a claim at the dealership. I did and after over two months the dealer again told me it is not covered. I paid about $1100 for the repair and told MBUSA that the dealer does not honor what the MBUSA letter says. Now even MBUSA does not honor what they wrote me in their own letter. They say if my car was non PZEV it would have been covered? How was it my fault to have a PZEV vehicle? Why did Mercedes had PZEV and non PZEV? How is it the customer fault. Both vehicles have the same issue but why one is covered and the other is not? Please you be the judge.
