Aggravating noise associated with high pressure fuel pumps, tick, tick, ticking noise at any speed. Complained to dealer, but despite exchanging pumps, noise persists. Complained to mbusa, was told this was a 'normal noise'. Sounds like an oxymoron to me. Very disappointed with car noise and response to my plea for help. *tr

At approximately 0030 friday august 07, I was travelling 65 MPH north bound on the ca215/60 freeway, there was little traffic. I heard what sounded like a gunshot, then a crincling glass sound and finally a whooshing of air I would soon see was a gaping hole where my closed panoramic sunroof use to be. I exited the freeway at the next exit and pulled into a gas station, got out of the car and upon inspecting the car found a huge hole where my panaramic sunroof use to be. I also made a video available at request.

06/22/2015 8,000 mi Crash ODI #10726601.0

This vehicle was purchased new in 2014. The vehicle has a reverse tilt function feature on the right passenger mirror. When functioning properly, the right passenger mirror tilts downward and to the right when the vehicle is placed in reverse so that the driver can see all objects to the right rear of the vehicle (in the vehicle's blind spot). Once the vehicle is shifted into drive, the right mirror is supposed to return to the driver's (memory) setting position for the mirror so that the driver is able to see out of the right mirror when driving on the highway. The mirror on this vehicle fails to return to the driver's (memory) setting after shifting the vehicle into drive after being in reverse. The mirror remains in the downward and to the right position thus leaving the driver c

Tl* the contact owns a 2014 Mercedes benz s550. While driving approximately 10 MPH, the vehicle downshifted and suddenly there was a hard shift when the accelerator pedal was depressed or when stopped at a traffic light. The contact also noticed that there was a loud noise near the rear of the vehicle. The contact also noticed that the tilt function feature on the right passenger mirror failed.

06/21/2018 ODI #11102977.0

According to the recall NHTSA campaign id number: 16v899000 and the vehicle inspection report from the local Mercedes dealership show as an identical issue. However, my vehicle is not identified as apart of the recall. The recall states the issue is due to the steering control unit not being soldered properly. Difficult to think this falls under normal wear and tear. I will get the repair done begrudgingly, though it would be nice if Mercedes would have stood behind its recall.

seatbelts 2 complaints shown

We almost got into crash the other day, our 8-year-old kid got our attention that rear seatbelt got very loose and did NOT retract back at all. he almost hit his head. when I asked him if it has been like this he said no, it was tight when I buckled it in. We tried several times to retract it manually with no luck. I checked online and I have seen people complaining about the same thing. we have been lucky we didn't hit the other car then my child will be seriously injured. This is a very serious safety requirement. I hope Mercedes Benz will take this very seriously as well, before others get hurt.

This past thursday evening (december 13, 2018) around 10:00 pm, I was driving (with my wife in the passenger seat) down a curvy stretch of road on sunset boulevard in beverly hills, when I suddenly heard a loud thumping sound and immediately felt violent vibrations through the steering wheel. Since we were traveling at a relatively low speed of 30 MPH, I was immediately able to re-gain the control of my vehicle and was able to pull over safely. Once I got out of my vehicle, I immediately noticed that the front right wheel rim had completely broken into two halves. I was shocked and very surprised because nothing could have possibly explained why this wheel completely broke in the manner that it did. We were extremely fortunate that there were no other vehicles around us at the time the
