2016 MERCEDES-BENZ E350 Complaints

We have been getting water in the front passenger compartment below the door area, after rain. We took it to our mechanic, who determined that the windshield integrity has been compromised along the top area in front of the passenger dash. Apparently the seal has separated, allowing water to enter the vehicle. Our mechanic stated that the safety of the vehicle has been compromised and the windshield needs to be removed and re-glued. We are currently waiting for an appointment with a glass specialist to have this repaired, as there does not seem to be a recall listed. Several months ago we had the drain(s) cleared and thought this would solve the problem, but it did not.

I received a letter from Mercedes-Benz USA LLC located at 1 Mercedes-Benz drive Sandy springs Georgia 30328 phone number 800-367-6372. This letter advised me of the extension of warranty coverage on the rear subframe of my vehicle to 20 years with unlimited mileage cover. I call my local Mercedes dealership where I purchased the vehicle to inquire about the severity of this problem. I specifically inquired as to whether this presented a safety concern or not. I was advised that the rear sub frame is the mechanism that holds the rear end of the car to the frame which if deteriorated enough would cause the rear end to separate from the frame resulting in problems with maneuvering the vehicle. Once I was advised of this I requested an appointment to go in and have the rear sub frame inspected to see exactly where the deterioration stands on this vehicle. In my opinion this is a definite safety concern and should have been classified as a recall rather than just a warranty extension. I was granted an appointment to have my subframe inspected tomorrow afternoon for which I specifically requested whether I would be charged or not and was advised I would not. I request that this be looked into by your agency as I do consider this a real safety factor. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owns a 2016 Mercedes-Benz E350. The contact stated that while the vehicle was parked and shut off inside the garage, there was an abnormally strong fuel odor detected. The vehicle was taken to the dealer, where it was diagnosed with a cracked fuel filter that needed to be replaced. The vehicle was then taken to an independent mechanic, who replaced the fuel filter. The manufacturer was not made aware of the failure. The failure mileage was 48,000.

I was driving my husband's 2016 E350 at 45 mph when the car accelerated. I attempted to control the speed by braking but the brake did not respond well. The steering wheel was also loose. The car sped up and turned left to the opposite side of the road, crossed the two lanes and hit the fence followed by a tree. The car was totaled, and the tree broke down at its branches. I survived the crush with two fractures on my back and on my left thumb.

The contact owns a 2016 Mercedes-Benz E350. The contact stated that water was leaking from the front driver’s side windshield. The contact also stated that several months later, she became aware that the front passenger’s side windshield was leaking. An undisclosed dealer was notified of the failure and the contact was provided an estimate for the repair, but no further assistance was provided. The vehicle was then taken to a collision center where it was diagnosed that the windshield bonding had failed and needed to be replaced. The vehicle was repaired; however, the failure recurred. The manufacturer was notified of the failure and the contact was referred to the dealer. The contact was then referred to the NHTSA Hotline. The failure mileage was approximately 39,000.

The contact owns a 2016 Mercedes-Benz E350. The contact stated while driving 30 MPH, the vehicle started shaking without warning. The vehicle was taken to the dealer for diagnostic test, and the mechanic stated that the ignition coil needed to be replaced. The vehicle was not repaired due to parts availability. The manufacturer was contacted and referred the contact to the dealer. The failure mileage was 63,000.

I was driving on North Shepherd Drive in Houston, TX, at a speed of approximately 35 MPH. While I was lightly braking to slow down for an upcoming intersection where I wished to turn, the car flashed 2 error lights--Frontal Collision Avoidance System Inoperable, and Traction Control System Inoperable. At that moment, the car began to accelerate out of my control. It began to accelerate at a pace comparable to a full-throttle acceleration. At that moment, I turned off the vehicle and coasted to the side of the road. After a moment, I turned the car back on, electrical components responded as normal. However, there was a fluttering movement on the RPM levels on the tachymeter--even at idle levels.

The car was in for (Aug 2022) annual safety and emissions state (PA) inspection and normal maintenance. Last performed Aug 2021. I was told that the car failed safety inspection because the Rear SubFrame had rusted through. A hole was present not just surface rust. The car has 58,000 miles and garage kept. The car was just (June 2022) in for all 4 wheel brakes replaced along with 4 tires. There hasn’t been any recall on this and they quoted Repair price of$5,400 and expect me to pay $1,000 towards that replace and repair. My question is clearly this is an inferior part. I’ve since investigated that recalls have been issued for the C model but not on the E which I own. If my car was in for inspection 12 mos ago and in for brakes 3 mos ago how long did it take to rust through? We’re talking about a hole not surface rust. I can’t believe that the hole just appeared anyway but within the time last safety inspection occurred. Why do I maintain the service recommendations and have safety concern that the manufacture will not own up to and that me and my family are at risk of an accident. I’n fact the service manager admitted that he is seeing more and more of theses failures.

I have the similar issue with my sun roof as described by this entry found on your website below: Started developing (April 2021) a rattle in car's roof along with occasional metal popping sound coming from rear of car. Continued to get worse. Then rattle stopped for a while and so did the metal popping sound. Now ( August, 2021)it sounds like there is a bolt loose in the sunroof area and the metal popping sound is really loud and I think coming from roof. Most of the time when car body twist, like going up a slight incline at an angle when entering a parking lot this incredible loud popping sound resonates throughout the entire car body. Played around on Mercedes website and it appears that Mercedes has problems with sunroof bolts coming loose. This is a safety defect -- if sunroof comes lose at 70 mph it is going to fly off and hurt or kill someone. Also strength of roof is compromised and if have accident where roof protection is needed it will probably fail.

Someone ran a stop sign traveling at at least 30 mph and hit my car twice; once in the front, once in the rear. I hit my face on the steering wheel, was knocked unconscious, and received a concussion. The airbags never deployed.
