I brought my 2005 Mercedes E320 [purchased Oct. 2014] in for an oil change Jan. 30, 2014. I mentioned to the service person a noise [like something broke] I heard while out of town visiting. He changed my oil and also found/replace a broken rear suspension spring. This occurred within 3 months of purchase. Repair cost: $551.17. My second incident occured Feb. 19th. I noticed a puddle of fluid underneath the vehicle [not sure what kind of fluid] and immediately brought the car back to the dealer for service. I was told the transmission servo solenoid seals required replacing. Repair cost: $157.84. The third incident was reported Apr. 21, 2014. I noted an increasingly bad odor inside the car since the first day of purchase, but wasn't sure exactly what it was as I was still trying to identify it. I finally realized it was gas I was smelling [intermittantly] inside the vehicle for the last six months. It turned out to be leaking fuel from the left fuel pump seal (lfps) underneath the rear seat. Repair cost: $161.31. The fuel odor got worse after the replacing the lfps. Most noticeably after filling the car with gas. I've also identified gasoline leaking from the drivers' side rear quarter that puddled by the tire. My feeling at this time, repairs may be onging for my E320, that I really like.

Slowing down for light and car tries to stall. After getting it home and in the garage, noticed strong gas smell. Took to shop and guy said gas leak from top of tank. Read about lots of complaints about this issue with other people with E320's.

The contact owns a 2005 Mercedes Benz E320. The contact stated the engine failed to operate at startup. The vehicle was towed to an authorized dealer for diagnosis. The failure recurred several times and the vehicle was taken to the dealer for each failure. The dealer was unable to locate the defect each time. The manufacturer was notified of the problem. The approximate failure mileage was unavailable. Updated 12/26/13 the consumer stated the vehicle can not be driven, because the check engine light is on, and the vehicle is leaking large amounts of oil. The motor mounts, transmission mounts, thrust arms, bearings and bushings were all replaced. The consumer stated the vehicle would lock on its own, after she un-locked it. The incidents happened several times. Also, there was an unusual sound coming from the vehicle, when it was stationary. Updated 02/05/14

From a stop the car would not accelerate beyond an idle, despite depressing the accelerator. It happened once on the highway after a tollbooth and almost caused an accident while merging. It also happened in the neighborhood after a stop sign. Problem is intermittent. Dealer could not duplicate problem and did not make any repairs.
