What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
While driving under 30 mph, vehicle randomly applies front or rear brake causing a loud braking squeal and causing the car to buck or pitch to one side. It has occurred from a stopped position as I started to accelerate, but 90% of the time it occurs at speeds under 30-35 mph while just driving in a simple or long…
Rear brake lamps failed over and over since vehicle purchased in 2001. Dealer replaced bulbs numerous times and last replaced l & r bulbs on 12/29/2006 at 29005 miles. In april 2007 a safety recall was issued for rear brake lamps failure.
The esp light comes on, the car pulls to right and the speed pedal does not work. It happens while accelerating and almost had an accident due to lack of power to cross a major intersection. The esp light comes on and automatically disables the speed/gas pedal.
The automatically dimming interior rear view mirror has leaked part of liquid crystal fluid, severely distorting the reflected image. In addition, since the mirror does not have ant manual adjustment for day/night selection, any bright lights from behind tend to blind or at least interfere with the proper vision.
The car does not accelerate for 5-6 seconds then surges. Lots of cars have this issue. Mb should issue a recall.
No warning lights or anything before the motor stops and the car loses power. Happens sporadically. Mercedes benz cannot detect the direct problem even after diagnosis. Continues to blame it on something else, then fixes it, but it continues to occur.
The engine died while I was driving in traffic. I managed to coast to a corner and get off the main street. After repeated attempts, the engine restarted and ran normally, only to die in traffic again about 5 minutes later.
Car hesitates sometimes when taking off and accelerating if I don't release clutch properly. It's as if the computer takes over and prevents car from accelerating. I've stalled cars; this is different. The stall is not related to the shifting but to the acceleration.
