The PRINX tires and the dealer - Mavis Tires, Auburn Avenue, Columbus, Georgia, are equally to blame for the flat I had in traffic endangering myself and other motorists with Brand New Prinx Tires, and also the skid I had at an intersection in Columbus Georgia. It's the old story of Chinese aftermarket parts that do not fit causing accidents. Prinx pushes Mavis to make sales of their 205/55/16 even though my Mercedes C240 door panel sticker shows the brands Mercedes lists for safety as in climates averaging 39 degrees and above for traction size 225/50/16 has to be placed in the rear (205 only on the front) and I did by buying more tires I didn't need and that stopped the skidding. MAVIS also installed the Prinx tires pretending to have replaced the dry-rotted stems, I had a flat at an intersection endangering other drivers, my wheel was also damaged. I have replaced the other stems and the rear tires which did not fit and had poor traction, but MAVIS will not exchange with me for a proper fit. I think Mavis should be fined as they are endangering motorists by not replacing dry-rotted stems to pinch pennies and deliberately placing tires on the rear despite the door sticker warning for size and fit and brand. The Prinx tires are also low on the ground like a go-cart, making the car harder to maneuver. The Better Business Bureau has so many complaints against Mavis Tire, home office New York, that I didn't bother.

As a time my vehicle needs to be renewal with california dmv , the recall part has not been available from mercedes manufacture. Mercedes benz does not provide any future time frame for the recall part that will effects on my vehicle registration renewal with dmv (it also means my renewal with dmv will be on hold and I don not have any other vehicle to drive if it happens by the time the current vehicle registration expired). I already contacted with local mercedes dealer and mercedes benz us but they can not do anything with the recall any time soon before my current registration ends. My vehicle is currently using and have no issue but I need to redeem a recall part so I can get a new vehicle registration at dmv.

Harmonic balancer /crank pulley wobbling very bad . Afraid it will come apart and cause catastrophic damage while my kids are driving. Mercedes covered this part under same engine family but only from model years 1998-2001. Would like them to take responsibility for the same faulty part as the others.

After filling my gas tank, there's a very strong raw gas odor inside the car while driving, and when parked. Seems stronger in the backseat. I see there's a extended warranty for this issue from mercedes benz on the e class for my year (2003). That warranty extension should have covered all classes with similar design or the same problem. The fumes are so strong I am afraid any spark could ignite the vapors. I really need your help! If mercedes benz acknowledged problems with my year (2003), it should include my c class unless they can establish the issues are totally unrelated in nature. Thank you for your assistance.

I bought the car yesterday, and today realized the car is leaking fuel, pooling under the back seat and spilling out under the car. The passenger headlight will not work; we tried 3 bulbs. The panel displays a message stating one of the tag lights is out, but it actually works.
