The contact owns a 2006 Mercedes Benz E350. While driving approximately 45 mph, the vehicle jerked, stalled, and the check engine warning light illuminated. In order for the vehicle to be restarted, the key had to be taken out of the ignition and re- inserted. The failure recurred on numerous occasions. The vehicle was taken to a dealer. The technician diagnosed that the balance shift and crank shaft needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 87,000.

PO16, PO17 needs to replace balanceshaft timing chain will cost 8-10K. Engine will fail if not replaced. There is a notice on this. Check engine light stays on. Mercedes refues to pay, cover cost when it is manufacturer defect. The engine should last longer.

Balance shaft manufacturing defect causes gear teeth to wear prematurely. This is a internal engine component. Poor materials caused the camshaft sprocket teeth to wear out thus this is a manufacturing problem. Internal engine components like balance shaft sprockets are meant to last at least 150000 miles on mb cars thus they are difficult to replace & repairs so expensive. Symtpom starts with camshaft position related check engine light - repair costs $7000. This occurs for many many many cars with that M272 engine. This is a environmental and safety hazard. Mercedes should be forced to do a recall.

I initially had issues with the transmission slipping then there were engine issues compounding the problem. Re the transmission, my first occurrence was when I was about to enter a very busy intersection and my car would barely move. My mechanic explained later that the car was stuck in 3rd gear so I could not get my normal forward movement. He told me if it happened again to turn my engine off, count to ten and turn it back on. Fortunately he told me this because the next times it happened I was on Lincoln blvd. In marina del rey, ca. And my car would not accelerate at all. One time I was at a red light so had time to turn it off and on. The next time I had to coast into a very small center divider that was growing smaller and with traffic flying by on my side and oncoming I had to turn off my engine, count to ten and turn it on. This caused a lot of angst since I had cars flying by and at me while doing this. There have been many other instances. I am getting no cooperation from mbz.

About a year ago (May 2013) we noticed gas smell in the compartment of the car. Initially it was sporadic. We thought it was from outside of the car or may be under the car, or gas tank cap was not tightened properly. After I took my car to Mercedes Benz dealership on 9/6/13, I found out that the smell was not from either of the above scenarios. It was indeed from inside the cabin and the Mercedes Benz technician told me that it was from fuel leakage under the back seat and it would cost $1380 to fix it. Additionally he said that he had seen numerous cases like mine, and some were so bad that they would not be able to drive it in, and had to tow the car in. Because of the high cost in addition to the other repairs that I had to do worth $1,200, I decided to delay this repair. Now we can not even drive the car because of the intense smell and will cost me probably more that $1,380 to fix it. I believe strongly that this is a manufacturer defect and should be fixed and paid for by Mercedes Benz.

After refueling, I noticed a strong odor of gasoline in the garage where I park my car. After driving the vehicle a few miles and parking in the garage, the odor was no longer there. I started noticing a pattern that whenever I refueled the vehicle, there was a strong odor of gasoline in the garage that dissipated once the vehicle was driven a few miles. Right after I started noticing the gas smell, the vehicle check engine light came on. I recently had the vehicle checked by an authorized Mercedes Benz service center who stated gas tank has crack at the top and is leaking fuel. The entire tank and all the components will need to be replaced at $3,000. I mentioned that there are a lot of other vehicles with this problem and a couple of class action lawsuits and it appears that the vehicle's gas tank is defective. The service technician refused to repair the components under any campaign or recall.

While driving 70 on hwy, check engine light came on, so I immediately stopped and called a tow truck. Mechanic's diagnosis was that the tumble flap was broken in the air intake manifold. The only fix is replacing the entire manifold for $2000 plus labor, tax and gaskets. The flaps are small and could be an inexpensive fix but all dealerships that I called confirmed that the only fix available is to replace the entire air intake manifold. Research tells me that this is a very common problem on this and many other models within the same years.

E350 6-cyl

  • 47,951 miles
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.

I have appr. 64,0000 miles on my Mercedes E350 and the check engine light came on. Sent it to the Mercedes dealership and said that the car had a balance shaft problem. Sold me the car in 2008. Service bulletins were out since 2007. Mercedes will only help minimally with the cost. Total cost so far is $3750. To much for me. Told Mercedes that I would have to drive around in a defective vehicle with my family and asked the rep. If that was safe, he replied "no". rep. Said that there was no campaign out on this problem. Something needs to get done before casualties occur.

I had so many problem with my Mercedes E350, but when the engine light was on I couldn't believe was the balance shaft. It was in warranty so I didn't pay a cent but when they returned the car back was not the same any more, the tail light was cracked and the A/C opening are inside. The car is not any more the same, sometimes is shaking, and has so many other problems. I saw online that Mercedes has to many cars with this defects that brings more problems, so I'm asking what are you waiting for a recall"????"
