2003 Mercedes-Benz E320 Recalls (Recent)

Brakes, August 8, 2005

RepairPal Expert Overview:

Due to deterioration of the wiring harness connection or failure of the hydraulic pump, the sensotronic brake control (SBC) system may default to the hydraulic back-up mode. In the back-up mode, the driver has braking power sufficient to stop the vehicle, but greater brake pedal pressure is required and brake pedal travel will be noticeably longer. Dealers will install a bracket and replacement ground wire to the SBC pump unit on all affected vehicles. Additionally, dealers will inspect and replace the SSC pump unit in certain SL models. The Mercedes-Benz recall numbers are 2005070007 AND 2005110001.

Brakes, October 21, 2004

RepairPal Expert Overview:

High mileage combined with a high number of brake actuations, or a high brake actuation frequency, can cause the pump motor of the SBC to run out of permissible tolerances. As a result, excessively high pressure may build the high pressure line of the brake system. If this occurs, the system will switch into the hydraulic function mode as designed. Sensotronic brake control is disabled when the brake system is functioning in the hydraulic mode. Dealers will inspect the SBC hydraulic unit and replace it if necessary to correct this concern. The Mercedes-Benz recall number is 2004 050014.

2003 Mercedes-Benz E320 Reviews

The MB E320 is a great car overall, we have been very pleased with it since buying it used last year.

Pros:
Very comfortable, yet responsive ride. Handles the snow surprisingly well.
Huge trunk and reasonably spacious back seat. Fits 3 in a pinch.
Solid feel, good fit and finish, and a great safety record.
Better gas mileage than I expected. We get 30+ on the highway with the V6.

Cons:
Repair costs are higher than average.
Plastic front bumper has peeling clear coat. I am not sure if there was a repair, but not the best finish on the bumpers.

Great car overall, a pleasure to drive and a sharp looking car as well. I would buy another if I could find a station wagon.
