1 Engine Exhaust System problem of the 2006 Mercedes Benz E350

Failure Date: 05/28/2013

Purchased 2006 mercedes-benz E350 4matic with 47,851 miles on odometer from mattie imports, inc. , fall river, MA on may 27, 2013. Automobile had approximately one-quarter of a tank of gasoline at purchase. Salesperson declined purchaser's request to "top-off" the gas tank prior to buyer leaving sellers lot. On may 28, 2013 buyer filled gas tank with fuel. Buyer immediately noticed a strong gasoline odor which continued after exiting fueling station. Odor progressed from exterior of automobile into automobile cabin. Buyer checked fuel tank filler cap and confirmed it was properly engaged. Buyer inspected the entire automobile for any leaking fluids and found none. The strong odor of gasoline persisted throughout the night while the automobile was parked in buyer's garage. Buyer left the garage door partially open and placed a fan in the opening and set the fan to exhaust in an effort to remove the strong fuel odor. The following morning the strong gasoline odor was still present. Buyer's 13 year old son was unable to withstand the odor and had to cover his nose and mouth while passing through buyer's garage. Buyer has experienced nausea and lightheadedness since being exposed to the odor. Upon research buyer learned that there exists and ongoing NHTSA investigation into this issue and a class-action lawsuit as well.

2 Engine Exhaust System problem of the 2006 Mercedes Benz E350

Failure Date: 09/01/2010

Check engine came on I took it to the dealer, the dealer stated that it was a faulty balance shaft gear and I received a $5000 (five thousand dollars) estimate for repair. I took it to an independent mechanic, he tried to replace the camshaft exhaust but the engine light was still on, he then determined the same problem faulty balance shaft gear. . . My car is only 74000 miles now, so much for a Mercedes Benz car under 100,000 miles. . Hope this to be a recall.

3 Engine Exhaust System problem of the 2006 Mercedes Benz E350

Failure Date: 02/03/2010

Motor oil leaking from camshaft plugs and from camshaft sensors leaking on to hot motor and on to hot exhaust components creating smoke which enters the heating/cooling system causing the need to open windows in winter. Have replaced two camshaft plugs at about 12 months ago at about 70,000 miles and scheduled another service call for camshaft sensor leaking oil at about 88,000 miles. Internet sites show similar failure on camshaft magnet senor component.

4 Engine Exhaust System problem of the 2010 Mercedes Benz E350

Failure Date: 10/28/2009

This complaint is for a 2010 BMW 535i xdrive. I went into the garage to start my car this morning Wednesday, 10/28/09 and the check engine light came on and the car started shaking. I moved the car out of the garage and shut off the engine to see if it would reset, I started the car up again and the check engine light was still on and the car continued shaking, I drove the car about 50ft to see if it would stop shaking and light would go out but it did not. I drove the car back into the garage and waited about a 1/2 hour to try it again it was the same problem. I contacted the service department whom advised me to contact roadside assistance to have the car towed in because it should not be driven. I had the car towed to open road BMW where I had purchased the car from two (2) months ago. I spoke with the service advisor and asked had anyone else experienced this problem he said yes on the 2009 and 2010 models it seems to be the fuel pump. There seems to have been a problem with them, but once they have been replaced that seems to have fixed the problem. I am waiting to hear back from the service department.
