2010 Mercedes Benz 350 e4matic rolled away after parked on hill , parking brake set, and engine off. The vehicle shift selector will not move to park unless key is out of ignition or shift lever is placed in park.
At 80mph, the front driveshaft u-joint failed, which caused a loss of power and a loud clunking sound. Vehicle would not move on its own power. Teardown showed a completely destroyed front driveshaft u-joint, damage to heat shielding, damage to oxygen sensors, damage to the catalytic converter, along with superficial damage to the bellhousing and missing brackets. Failure is suspected to the geometry of the front driveshaft, which connects at an angle from the transfer case to the front differential on 4matic-equipped vehicles. This introduces additional stress to the u-joint, making it prone to failure.
