My vehicle is having the same issue as follows in quotes from a Mercedes recall Campaign No.2017020018 (attached) : Replace Steering Column Module. Here is the description of the problem from that Mercedes recall "This Recall Campaign has been initiated because Daimler AG (‘DAG’), the manufacturer of Mercedes-Benz vehicles, has determined that on certain E-Class vehicles (213 platform) the column-mounted shift lever module might become inoperative due to possible damage to the internal circuit board. As a result, the vehicle might not move forward or rearward with the shift lever as selected by the driver. However, both the auto-P function and automatic parking brake will continue to operate as intended and prevent the vehicle from moving forward or rearward. If the vehicle does not move forward or rearward with the shift lever as selected by the driver, there is an increased risk of a crash" In my own words, on an intermittent basis, I could be in reverse, move the steering column shifter to drive, but the vehicle remains in reverse. Or, I could be in drive, put the steering column shifter in reverse, but the vehicle remains in drive. This problem is intermittent. It could happen many times in one day, and then not happen again for many weeks.

Motor mounts and transmission mounts continue to fail at intervals or 13,000 miles and again at 16,000 miles. Vibration of transmission is scary. Mercedes has replaced the mounts many times. They refuse to install new Transmission mount now after only 16,000 miles on the replacement. I have contacted MBUSA and they are telling me , they will not help with these substandard parts. Very well-known issue.

While driving down the road at 60mph, I hit the brakes to slow down. I heard a pop and thunk from the rear of the vehicle. I thought it was some boxes in the back of my car and forgot about it. I then brought my car into the dealer for an engine computer update and during the inspection they found that the passenger rear control arm mount broke away from the sub frame and that the rear brake lines were heavily rusted. They quoted a new rear subframe and brake lines. If I was on the freeway and this happened or I had to take evasive maneuvers I most likely would have crashed. The mechanic told me the weld broke where the control arm mounts to the subframe. He inspected the rest of the vehicle and everything looks good. On a less than 9 year old vehicle the subframe should not have rusted enough to break. Especially on a safety issue like the suspension and brakes. Mercedes should have done a better job with their welds and with their rust proofing especially on safety components.

Have purchased a 2014 mercedes E350 59k miles. This vehicle has an issue as so do many Mercedes with their rear subframes rotted out at the control arm bracket which causes the rear link/thrust arm to detach from the subframe/axle carrier and posses a danger when breaking due to the rear spindle assembly flexing throwing the wheels out of alignment and could be at risk for a car crack. This vehicle has already been in a minor crash as a result of this issue. I personally have not brought it to Mercedes to get it diagnosed inspected or the police law enforcement but there are many cases online on the Mercedes Benz forums to which this has also happened to. This issue applies to other Mercedes models ranging from 2010 all the way to 2016. Videos of the exact vehicle brought to an independent shop available upon request.

Mercedes Benz had a previous recall Campaign # 2009100001 which affected vehicles until 2012 and mine is a 2014 model E350. It has the same issue with Engine severely misfiring and jerky on the road as if it is going to STOP IN THE MIDDLE OF FREEWAY while driving and cause a SAFETY RISK for my family and others on the road. Specific component is Oil leaks from transmission wiring harness and ECM connector. The leak is from camshaft hall sensors and transmission drain plug. Mercedes Benz dealer in Pleasanton, CA has confirmed the issue after I paid $218 for diagnosis.
