Steering wheel will move in and out, but has stopped moving up and down. The steering wheel is stuck in the UP position. This has caused me to readjust all my seat settings and has made it more difficult to see the dash.

The contact owns a 2017 Mercedes-Benz S550. The contact stated while the vehicle was in for routine maintenance, the mechanic discovered that the front driver's side CV-boot had cracked and was leaking oil. The contact was advised that the CV-boot could cause the front axle to eventually fail. The contact was advised that the front axle needed to be replaced. The vehicle was not yet repaired. The manufacturer and local dealer were notified of the failure, but no assistance was offered. The failure mileage was 76,000.

This car since new has had moisture in the headlight from rain or washing. MB has installed moisture packets in the headlights that they said would fix the problem. It never did. I called the dealership and complained, they said sorry but that was their fix (MB TSB LI82.10-P-062051). Now the lights have failed, and they want me to spend $10K to replace the headlights and continue with the same issue. The problem still exists with the new headlights. This is not only a poor way to fix an ongoing problem (Moisture packets) for something that is severely related to safety on the highways in America. I believe you will agree. Please respond? Thank you

The dashboard is separating where the airbag is on the passenger side and also the driver side which could deploy the airbag

I was sold a vehicle by a dealership with a busted gas tank. It appears to have been an attempt to repair it with patching material. I am unsure if the defect was a result of manufacturing versus acquired damage. My safety is at risk because of leaking gas that could potentially ignite and inhaling strong gas fumes that could impact my lungs and health. The fuel tank damage has been confirmed by a mechanic and documented. It has not been inspected by any other entity while in my possession other than reported inspection by the dealership. I secured the vehicle on [XXX] from the dealership with these safety concerns. A mechanic stated the damage could have resulted either with the dealership or during on and off the trailer during transport of the vehicle from Florida to Indiana.

Had my S550 into this dealership two (2) consecutive years for a power steering rack issue that ended up being related to rodent damage. The first time it happened the dealership replaced the wiring free of charge after discovering it, after initially telling me that the rack itself would have to be replaced. This year both the wiring and the rack itself needed to be replaced, and I was made to go through my auto insurance to have it fixed. My sons Cadillac, and my girlfriends Range Rover Sport share the same driveways with me, and have had no rodent damage. I did a bit of research and found that Mercedes now designs their cables with soy based materials, which attract rats, so the fact that my car has been eaten twice is more or less by MB design, as they apparently care more about the environment than they do about my ability to steer my car continuously for 1 year straight. My service Manager and his Manager acknowledged that they see this a lot, and were laughing when I asked for an inedible cable. I submitted a complaint to MBUSA, one which I had to continuously follow up on, as they weren’t proactive at all, and after contacting me this AM, they informed me that they don’t see a problem, and are not considering reimbursing me for my $750 deductible, or the 3 + weeks that I was without my car between both incidents. My issue isn’t necessarily with the dealership, although if they are quick to acknowledge that their cables are attractive to animals, they should have in my

The leather is coming out of the dashboard as a result of that the air bag on the passenger front window is coming out. you can literally see the white part of the air bag. its a matter of time before the leather comes out all the way and the air bag will pop out. the dealer refuses to fix it and the car is still under warranty.

The contact owns a 2017 Mercedes-Benz S550. The contact stated the vehicle's front passenger seat belt failed to lock into the seat buckle. The failure occurred intermittently. The contact had taken the vehicle to a certified mechanic who stated the entire seat belt buckle needed to be replaced. The vehicle had not been repaired. The manufacturer was made aware of the failure and informed the contact that the VIN was not included in NHTSA Campaign Number: 16V829000 (Seat Belts). The contact was advised to contact the NHTSA Hotline. The approximate failure mileage was 100,000

The manufacturer was not notified of the failure. The failure mileage was 38,000.

The vehicle panoramic sunroof came across a discrepancy that can damage the owner and other innocent vehicles on the road. Since it has been stuck on one side it can possibly break and fly off. The vehicle has been recalled, unfortunately my vehicles vin number was not chosen although it has the similar problems that the recall vehicles had. The front roof panel located between the windshield and the panoramic sunroof may not have been bonded correctly to the vehicle during a prior repair.The adhesive bonding of the front panel might deteriorate, possibly causing the front panel to detach from the vehicle and become a road hazard, increasing the risk of a crash.

STARTING OUT FROM AN INTERSECTION THE ENTIRE ELECTRICAL SYSTEM DIED, NO ENGINE, NO LIGHTS, NO ABILITY TO OPEN TRUNK, NOTHING. I AM REPORTING THIS BECAUSE I FEAR SUCH AN EVENT COULD BE LIFE-THREATENING, EG. IF IT HAPPENED WHILE TRAVELING AT A HIGH SPEED. I BELIEVE THE AIRBAGS MAY HAVE BEEN DISABLED ALONG WITH ALL OTHER ELECTRICAL. DEALER REPORTS THERE WAS A SIMILAR EVENT WITH ANOTHER OF THE SAME CAR ONE WEEK EARLIER, AND THAT IT IS APPARENTLY CAUSED BY A CONTACT FOR THE BATTERY GROUND "BURNING OUT." I BELIEVE THERE SHOULD BE AN URGENT RECALL.

AS THE DRIVER THESE AREAS IMPAIR MY VIEW AS I LOOK AHEAD AND SCAN THE VIEW FROM 60 DEGREES TO MY LEFT OR RIGHT (IN MY SPECIFIC SITUATION). THIS AFFECTS THE IMAGE I SEE OF PEDESTRIANS OR BICYCLISTS WAITING TO CROSS THE CROSSWALK OR ROAD IN FRONT OF ME.
