Mercedes-Benz Problems

Electrical & Lights -- Verified

Instrument cluster displays tend to fail, especially the clock and gear indicators. Our technicians tell us the instrument cluster will require replacement to correct this issue.

Heating & Air Conditioning -- Verified

A repetitive clicking noise from behind the center area of the dash panel is usually caused by a broken stepper motor actuating arm. The actuating arm controls the direction of air flow in the climate control system. Disassembly of the center console will be required to access and change the broken arm with the updated, reinforced part.

Suspension & Steering -- Verified

The active body control system can leak fluid from numerous areas, including the tandem pump, hydraulic lines, struts, and/or seals. If it is not repaired, the vehicle ride height could drop too low and cause damage to the undercarriage.

Drive Train -- Verified

Vehicles equipped with a 7-speed automatic transmission may develop a rough shifting condition, most commonly going up from first to second gear and going down from third to second or second to first gear. Our technicians tell us this is due to an internal component failure. Mercedes has released updated parts; the transmission will need to be removed and disassembled to complete the necessary repairs.

Engine -- Verified

The camshaft adjuster solenoid (which is related to the variable valve timing system) may fail or timing chain/balance shaft components may wear, resulting in illumination of the Check Engine Light and various drivability issues. Mercedes-Benz has released a service bulletin outlining specific repair instructions depending on fault codes stored.

Sensotronic Brake Control System May Default to Basic Hydraulic Mode

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.

i have problem with key look door

car has winning noise, also steering wheel rattles when making lft turn...

126K miles. Well maintained. Have the gear box problem now. Mostly was jerking when started recently. My mechanic is suggesting to get a used transmission with 90 days warranty. This will cost me a little over $1000. Never had a experience with a used part. Wondering if it is worthy to replace the gear box or sell or donate the car. Thanks

I bought my e320 in 2006 it had been repoed and it had poor maintenance,but I replaced everything under the hood,including all plugs,,wires,,converters,,the whole ball of wax,,this car as a whole,,is awesome .It rides and drives great,,,i just repainted it two months ago, and no major issues,,All in all this is an awesome car and looks good,,and the stereo is killer Ha,

Love this Vehicle. I purchased this vehicle brand new. It is a very
reliable car. I agree, I too have experienced failure on the LED
display on instrument panel (very annoying)-Mercedes should issue a
recall on that. Also, my biggest issue, IS THE RUST on the door.
REALLY???This vehicle has a HIGH PRICE tag and holds the Mercedes
Brand, yet the Manufacture will not stand by their product. Ugh!!!!

Eventually a class action suit will be filed on this vehicle. I
am happy with its strong engine, it is a very spacious vehicle, has
a nice large trunk (which was able to hold baby items), really like
the round lights in front. They should also design a stronger mirror
closure on the visor.

All in all, very happy, except for the BODY RUST.
