2006 Mercedes-Benz R350 Problems

Internal Component Failure May Cause Rough Shifting

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.

Camshaft Adjuster Solenoid Failure

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.

2006 Mercedes-Benz R350 Recalls

Incorrect Software Calibration May Cause Fuel Pump to Remain Powered in a Collision

There is a faulty software calibration that affects several areas including shutting off the fuel supply in a collision. This could cause a fire hazard during an accident. Dealers will reprogram this software. The Mercedes-Benz recall number is 2008 070001. This recall began during August, 2008.

Wire Harness to Starter Motor May Be Damaged

The wiring harness to the starter motor may be routed incorrectly. This could lead to chafing of the protective sleeve on the engine mount cover. Over time, this chafing could wear through the sleeve and expose the underlying wiring. Damaged wires may result in a electrical short and loss of function of the vehicle's electrical system. Dealers will inspect the wiring and correct its routing. If necessary, the protective sleeve and/or wiring will be replaced. This recall is expected to begin on May 12, 2006. The Mercedes-Benz recall number is 2006040002.

Second Row Seat Belt Buckle May Come Loose

Some second row seats were manufactured without threads in the nut used to secure the seat belt buckle. In the event of a crash, the buckle may not hold as designed, increasing the risk of injury to a second row seat occupant. Dealers will inspect the second row seat and replace it as necessary. This recall is scheduled to begin on May 3rd, 2006. The Mercedes-Benz recall number is 2006040003.

I have replaced the cam sensors, rear air sprongs,brakes and rotors...
We bought the 2006 R350 used in 2008 with 30,000 miles on it for $18,000. This was when gas prices were so high and no one was buying any SUV. They needed to move it and we figured, you can't buy a Prius for $18,000. It had the factory warranty until 50,000 then we bought an extended warranty which will cover it for 5 more years or until 100,000. We needed a car (not a mini van) that could seat...
