2014 Mercedes-Benz E350 Steering Problems

While braking from highway speeds or any other speed, the vehicle becomes unstable and pulls to the left, making it difficult to maintain control. During hard braking, the vehicle does not track straight and requires steering correction to remain in its lane, creating a significant safety hazard. To diagnose the problem, the vehicle was inspected by an independent mechanic. An alignment was performed, and the suspension and braking systems were inspected. The mechanic determined that the rear subframe has severe rust and corrosion. The rusted rear subframe is available for inspection upon request. Despite the alignment and inspection of the suspension and brakes, the unsafe braking behavior remains. There were no warning lights or messages indicating this condition before it was discovered. The problem has been reproduced multiple times under similar braking conditions. This condition puts the driver, passengers, and other motorists at risk because the vehicle can become difficult to control during braking, particularly at highway speeds or during an emergency stop. Based on the mechanic's inspection, the severely corroded rear subframe is the source of concern and should be investigated as a safety-related defect. I have also contacted Mercedes-Benz USA regarding this safety issue and requested assistance, but I have not yet received a response.

While driving, the steering from left to right started to get choppy or hard. With the cruise control on, I ran off the road because of the fight between the rack and pinion(steering wheel) and the cruise control.

Car unexpectedly swerves while driving!!

Incident

On 11/24/23 Mercedes Benz had replaced my subframe which was part of a safety recall. When I arrived home after picking up my vehicle, there was a loud bang from under the vehicle. I immediately called the service department and told them about what happened and also complained that the steering wheel was cocked to the left and pulling in that direction. My service advisor John advised me to bring it back the next day which I did. They never told me what caused the loud bang, but they did say another front end alignment was done. The vehicle still continued to pull and the steering wheel was still off center. On [XXX] I took my car to Mr. Tire for a tire rotation because the car continued to sway and jolt when going over bumps. It also made a popping noise when making a sharp turn. Then on [XXX] as I was driving, the car pulled or slid to the left. In order to keep from crashing into another vehicle, I pulled the wheel right causing me to run over the medium and almost crashing into a building. I was extremely shook up and in disbelief. Has this type of thing ever happened to anyone else before after the subframe was replaced? INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Driving on a highway approximately 65 MPH. Had to break fairly hard due to unexpected traffic. When breaking, my car fishtailed and I thought I was going to hit the vehicle in front of me. I immediately took my car to my independent, Mercedes-certified repair shop. My mechanic informed me that it was a problem with the rear subframe. I then took it to Mercedes for an inspection. They confirmed that the rear subframe was rusted and needs immediate repair. I was told not to drive the vehicle as it is extremely unsafe. Mercedes is aware of this problem. There was a class action lawsuit filed in February of 2023. Mercedes supposedly informed owners of the potential problem, but I was never notified. I only became aware of this dangerous subframe problem as a result of this incident.

While driving on a local road, my wife lost control over the steering wheel of our 2014 Mercedes-Benz (MB) E350 sedan (the instrumental panel showed "Power Steering Malfunction: see attached photo)". It was a very dangerous situation, but she somehow managed to find a place to pull over and call me. It could've been much more dangerous if this occurred on highway. We found some information about the Power Steering Failure recall and our 2014 E350 was included as an affected car. Here is the website with that information: https://repairpal.com/recall/16V899000 However, our local Mercedes Dealer checked and found our car was not included in the recall list. The problem we encountered is identical to the nature of the recall, so we don't understand why our car is not included. The dealer recommended me to call MB Customer Service, which recommended me to contact NHTSA, so I'm contacting it. I hope you help us drive safely by adding MB 2014 MB E350 into the recall list. We need the car desperately as soon as possible. Thank you in advance for your help.

My electric power steering failed. It often resets and can be unpredictable when it wants to fail again. It’s an intermittent problem that local dealer tried to fix with a software update but did not work. I was told I need a new steering rack at $5-6k which is unacceptable for any vehicle that has been maintained it’s whole life . My car is 8 years old with 100,000 miles with full service records I feel like this is a premature failure of the electric power steering

The rear sub-frame involving vehicle stability under braking and turning. A component that should remain attached to the vehicle has broken off due to corrosion. My vehicle is not that old that a key structural component of the car should break at the weld/attachment point. I have video of this defect. But its greater than 10MB and will not let me upload it is there an email I can send it to ?

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.

'STEERING WHEEL MALFUNCTION' DISPLAY WHILE DRIVING. THE STEERING WHEEL COULDN'T BE TURNED. I COULD EITHER GO STRAIGHT OR REVERSE, BUT COULD NOT TURN THE STEERING WHEEL. I WAS DRIVING OUT OF MY NEIGHBORHOOD, ALL OF THE SUDDEN, THE DISPLAY POPPED UP, BEFORE I WAS GOING DOWN THE CURVY HILL. THIS IS DANGEROUS THAT IT CAN JUST HAPPEN WHILE YOU DRIVE. IT CAN TAKE SOMEONE'S LIFE IF DRIVE OUT ON THE FREEWAY AT A HIGH SPEED AND THE STEERING WHEEL CANNOT BE TURNED. IT IS ALSO DANGEROUS FOR ME TO STOP IN THE MIDDLE OF THE STREET IN MY NEIGHBORHOOD BECAUSE I COULDN'T TURN LEFT OR RIGHT TO EVEN PARK THE CAR SAFELY. I WAS LUCKY THAT THE DISPLAY POPPED UP AND THE STEERING WHEEL MALFUNCTION OCCURRED BEFORE I DRIVE DOWN THE CURVY HILL TO GET ON THE FREEWAY. HAD THIS HAPPENED WHEN I GOT ON THE CURVY HILL OR THE FREEWAY, A POTENTIAL DEATH ACCIDENT COULD HAVE OCCURRED. *TR

POWER STEERING MALFUNCTION (CANNOT TURN BUT THE POWER WAS STILL ON. THE SCREEN IN FRONT OF DRIVER'S SEAT ALSO SHOWED THE MESSAGE.) SUDDENLY HAPPENED IN A SECOND WHEN I DROVE IN A LOW SPEED (AROUND 25-30). I WAS VERY VERY LUCKY ENOUGH TO SLIDE MY CAR SLOWLY BY THE CURB SINCE THE TRAFFIC WAS NOT HEAVY. I GOT MY CAR TOWED TO THE DEALER WHICH I JUST FINISHED MY YEARLY MAINTENANCE 10 DAYS AGO. THEY FOUND MY CAR'S COMPUTER HAD A BUG. THEY RE-PROGRAMMED MY CAR'S COMPUTER IN THE NEXT DAY. THE PROBLEM HAS SOLVED SO FAR. THIS HAD HAPPENED ABOUT 2 WEEKS AGO. I GOOGLED TO FIND THIS PROBLEM SEEMS HAPPENED A FEW TIMES BEFORE BUT NO RECALL. I DID THE MAINTENANCE WITH THE DEALER EVERY YEAR. DUE TO THE DEFECT AND DEALER'S NEGLIGENCE, MY LIFE HAD SERIOUSLY THREATENED BY THIS CRITICAL SITUATION. I WOULD URGE YOU TO INVESTIGATE THE SEVERITY FOR THIS CASE TO AVOID OTHER ACCIDENTS HAPPENING.
