Known Problems

The brake light warning message for a burned out bulb may be displayed. Our technicians tell us the tail lamp housing may melt and distort causing a poor connection at the bulb. The lamp housing should be replaced to correct this condition.

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.

The engine may develop a stalling and/or no start condition due to a failed crankshaft position sensor.

AC system leaks and/or a faulty evaporator temperature sensor can cause poor AC cooling. The failed sensor can prevent the AC compressor from coming on. Leaks cause a low refrigerant level, which reduces the ability to cool.

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.

It is not uncommon for the power steering rack to develop a fluid leak requiring replacement of the rack assembly. Loss of power steering fluid may also cause an abnormal noise and damage to the power steering pump.

A problem with the ball joints can cause a creaking noise. There is an updated part to remedy this problem.

Motor mounts commonly fail, causing engine vibrations to be transferred to the body. Failed motor mounts should be replaced in order to prevent damage to the transmission mount.

The covering for the center console can bubble and discolor. Replacement of the affected part is most commonly only way to repair this concern.

Due to slipping clutches in the transfer case, a shudder or rumbling from the center of the vehicle may occur, especially when turning at slow speeds. If the clutches are not too badly worn, changing the fluid will fix this problem. Otherwise, the transfer case will need to be disassembled to change the clutches.
