What 2007 Mercedes-Benz E320 owners say
Transmission & drivetrain
Highway driving, cruise control set. Cruise control beeped, disengaged. Car continued to drive normally until I had to stop for a light. When light changed to green, the car would barely move - had no power, even though the rpms showed the engine running. Fortunately, I was near a gas station and was able to get off the road. This could have been very hazardous had it occurred in heavy traffic.... I pulled off the road, restarted the car and everything seemed to be fine. But this car basically left me sitting in the middle of the road and could have caused a serious accident if someone had been approaching me from the rear, or it was in the intersection at the time.
Transmission violently downshift several gears without warning .this causes skidding, throwing occupants violently toward the wind shield this happens when auto is in drive with speeds between 40-45 MPH. This unexpected lurching causes loss of control on wet and dry pavement. This defect has been reported to Mercedes Benz with no corrective action offered.
Engine & cooling
While trying to merge into highway traffic (i94 in michigan) I pressed the accelerator to gain speed to merge only to find that the engine lacked any power, the rpms rose slowly but there was little to no acceleration. I was told (by Mercedes dealer) that this is a known issue and in this case it almost caused my death. If this is a know issue why are our lives being put at risk because of a poorly designed part?
Tl* the contact owns a 2007 Mercedes Benz e230. The contact stated that when attempting to accelerate, the vehicle failed to shift from first gear and the check engine warning light illuminated. The vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure. The failure mileage was 65,000.
Fuel & propulsion system
Fuel tank leak at the top of the tank. MB has well documented gasoline leaks for MB model 211 years 2003-2008. Notices were sent to owners of gas powered auto's but none were sent to DIESEL auto owners. The exact same procedure and parts are needed to repair DIESEL tanks as gasoline tanks. Either this is a oversight by MB or the problem was ignored. My DIESEL tank is leaking exactly as other documented gasoline MB vehicles model 211.
Noticed strong smell of diesel fuel by left rear tire, in several days a leak was under left tire, had fuel tank sending unit gasket replaced, no visible leaks but fumes are still present 1 year after repair. When repair was made all related parts were cleaned of residential fuel. Want to know if MB has dealt with splits or cracks in fuel tanks.
