E320 6-cyl

  • 139,000 miles


First incident, brakes, visit workshop message appeared on the information system. Took the car to the dealer and vehicle was diagnosed with sbc pump failure. Mercedes had extended this warranty to 10 years because of know defects to the part so all parts and labor were covered.

E320 8-cyl

  • 120,000 miles
The warning light of brakes failure came on at highway exit at 65mph and the brake paddle hit the floor with no brakes. Pulled over and took the car to the dealer in mid March and was told by the dealer that this is the sbc pump that failed which would have been covered by Mercedes Benz under service bulletin no.: 484656 but the warranty expired on 02/28/13 and since I was 15 days over this will not be covered. Contacted Mercedes Benz of na and asked them that I bought the car used and was not told by anyone about this tsb and they should cover the repairs since the pump actually failed when the car still under extended 10 year warranty (service bulletin no.: 484656 ). they flatly refused. I than asked that if this was a known issue that the brakes could fail completely than its Mercedes duty to tell the owners even if they buy used, the person just kept quiet. People can actually get hurt or die when this failure happens. At the end I was charged $2309 for something that was a known issue by Mercedes.

The contact owns a 2003 Mercedes E320. The contact was driving approximately 50 mph when the brake warning light illuminated on the instrument panel. The contact depressed the brake pedal but the vehicle would not respond. The vehicle eventually came to a stop. The contact shut the engine off and after restarting the vehicle the brake system functioned without failure. The vehicle was not taken to the dealer for diagnostic testing. The VIN was not available. The vehicle was not repaired. The approximate failure mileage was 160,000.

problem #1

  • 86,150 miles
While driving at 45mph to go to work my car lost the brakes. The display showed brakes defective. Luckily I had plenty of space to stop the car with emergency brakes. I did diagnostic on the car and the sensotronic brake control sbc unit as Mercedes-Benz calls it (the brake unit) was defective. This is unacceptable defect and could be life threatening to others if they loose the brakes like I did while driving. Dealer diagnosed the car as well and replaced the sbc pump.
