The car shuts off randomly at stop lights. I cannot tell it is off until we are a green light and then I have to start the car. Cars behind me have almost hit me
2012 Mercedes-Benz E350 engine complaints
Page 2 of 2: complaints 11 to 21 of 21, newest first, as owners wrote them.
The cam solenoid sensors are picking up oil, then it is being disbursed in to the electrical systems of the vehicle. It is flowing into, o2 sensors making the vehicle run in a full rich mode, it is reaching the computer system that runs the entire vehicle. This repair can cost upwards of $8000. I have done online research and it is a very common issue amongst many mercedes vehicles. The issue is a known problem, it was being repaired but mercedes stopped the repair. It comes from an internal issue, not a fail to maintain problem. I contacted mercedes, they say they don't know of the issue, but they did tell me, they know how to fix the problem for a cost of over $ 5000. To us. Online searches have resulted in many complaints by owners. Regular driving is a result of the issue. Now we can't drive out vehicle due to fear of the oil in the electrical lines reaching our cpu for the entire car, which will result several thousand more dollars on top of the repair cost. We have paid $ 800. At this point only to be told, do not drive the care or worse damage will occur. So we have a beautiful car that is collecting leaves and dust. I await your response, garyw. Smith. We contacted mercedes bens of raleigh nc, they are our contact point, they don;t know of an issue but know the cure for $5000. Plus dollars, hmmm, curious...

Fan fire. Oil smelling smoke which turned to flames.
Engine. Problem started in march 2017. 2012 e350 conv made a loud grinding metal on metal noise on cold start, but would fade out in a few seconds. Brought car to dealer, who said mechanics could not duplicate problem. Brought car home and car continued to make grinding noise. Took video of noise on cold start so I could show my service advisor. Mercedes said to replace engine tensioners, total cost of repair 1900.00. Brought car home. Car continues to make grinding sound on cold start. Brought car back. Mechanics suggested changing the oil pump, total cost 570.00. Brought car home, and car continued to make grinding noise on cold start. Brought car back to dealer for the third time, who then called mercedes for advice. Service advisor said mercedes thinks that the car has a camshaft problem and the cost of parts alone would be over 5000.00. My car was in the shop for over 2 months and there was still no definitive answer as to what was causing the grinding metal on metal noise. This is absurd as I have had my car serviced regularly and it is garaged in great condition. This is obviously an engineering/mechanical defect and should be considered a lemon since mercedes has not been able to fix or diagnose the problem in a timely manner. As of today, feb 17, 2019, my car is still making a grinding metal on metal noise on both cold and warm start. Just wondering if one day my engine will suddenly blow up on cold start...
2012 e350 coupe. Car was making an odd "clunking" noise when started, but would fade or idle out after a couple of seconds. Took it into mb service today and was just informed that my car has a camshaft problem and it's wearing on the right cylinder head. Service rep says they have seen several cars come in with the same issue. Repairs cost $9,000! Seems like an engineering/mechanical defect as I was told there was nothing I could have done to prevent this issue.
When starting the vehicle has a slow start. When in motion the vehicle drives rough, and cuts off, then the check engine light came on. This vehicle has a great maintenance record only serviced at the mercedes dealer and has 0nly 54000 miles. This is clearly an engineering issue which was a safety issue. Mercedes repaired. They found the camshaft damaged, head damaged, and gear damaged and replaced camshaft and gear only. They charged my for their engineering failures $4874.38. For this engineering and safety faikure I believe this vehicle should be recalled before the lost health and life is lost, and owners should be recompense for the damage.
Ticking/ tapping noise from the engine bay when car is excelerating, especially when going uphill.
Tl* the contact owns a 2012 mercedes benz e350. While the vehicle was parked and the key was removed from the ignition, the vehicle jerked and rolled backwards before stopping independently. In addition, the contact heard an abnormal noise and the vehicle veered to the left when reversing. The dealer was unable to diagnose the failure but made the following repairs: the cover on the front passenger side cylinder head, removed/installed a seal, non-return valve, chain tensioner, sealant mb, flange gasket, hexalobular bolt, the cover on the front driver side cylinder head, removed/installed a seal, left and right secondary drive chain tensioners, front cover cylinder, and the check valve. On another occasion, the vehicle rolled in reverse and crashed into the bumper of another vehicle. The door of the vehicle bruised the contact and medical attention was required. The vehicle was towed to the dealer. A police report was not filed. The dealer was not able to diagnose the failure and the vehicle remained at the dealer. The manufacturer was notified of the failure. The approximate failure mileage was 5,597.
While driving on an express way in dallas, texas my GPS made an error concerning an exit and I was required to divert quickly to the left to make exit lane .time was 6:00 pm ,heavy traffic conditions and road and weather conditions were excellent and dry. My mercedes pre activated a skid mode and there was approximately a 70% cut back in engine power .a yellow engine light came on and skid mode came on operator screen but there was no skidding taking place. I was helpless with no power to keep up with the 50-60 MPH traffic while trying to get into lane .consequently a semi tractor struck my left rear fender /bumper causing damage to my mercedes. There was no damage to the tractor. According to mercedes the vehicle was supposed to do this as a safety feature. If this is true then they actually in my opinion while developing safety features created another un safe condition where as the semi could have run over my wife and I killing us both. This was truly a near miss and we are very much concerned about it happening again to us or some one else, resulting in a fatal accident, not just a fender bender. Mercedes is in denial concerning any un safe condition and refused to take any responsibility for any damage that this car caused. Please review this vehicle for possible call back before some one does get seriously injured. Perhaps skid mode or traction control may be helpful but engine cut back and power loss needs to be left to the operator not the vehicle controlling it's self. Your help would be graciously appreciated.
