What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
15 seconds later, vehicle caught on fire. Due to severe fire damage vehicle was a total loss.
The explanation they offered is that the likely cause of the failure in fuel delivery to the engine, while driving, is the fuel pump, mercedes part# [phone]. However, they further explained that the only way to replace a faulty fuel pump is to replace the entire fuel tank, fuel delivery unit, fuel sending unit and…
He had us bring it in right away and he lifted up the rear seat where our children sit and showed my husband and myself a pool of gasoline coming from the fuel pump sitting right under the seat!! I was disgusted to know that mbusa dismissed this so quickly and could have potentially put our children at risk.
This car has also recently shown evidence of rusting. I contacted mbusa about that and learned that the mb corrosion protection in the u.s. Is merely four years. I also found that most of the other german luxury automakers have used galvinized steel for decades, unlike the manufacturing practices of mb.
The cars instrument cluster also sometimes doesn't work, the power steering leaks intermittently the rear coil spring broke on left side of vehicle . The alternator was replaced so was the coil pack and other items by mercedes but they always tried to justify that problem was normal wear and tear which is not true.
Was told I needed a fuel pump. I paid $1,500 to have a new fuel pump installed. Problem not solved. When I tried to start the car. It hesitates for about 10-15 seconds before it turns over. I took it back to the mechanics and was told it needed to fuel filter changed again. Problem not solved.
Power seat controller becomes defective and fails to shut down when car is off and locked, and thus drains the battery.
Defective seat controller modules ( driver and passenger ) cause the battery to drain completely within 24 hours. This leaves me stranded and unable to drive my vehicle.
