TIRES

2 complaints

The driver front tire was found to have failed at the time of an oil change at approximately 15,000 miles. The tire was torn at the junction of the sidewall and tread in several areas. This tire is no longer available. No incident occurred. The passenger front tire was found to have the same defect when I performed a seasonal tire change but the conditions were worse at approximately 17,000 miles. No incident occurred. The tire will be taken to the dealer for inspection. Photos of this tire attached. 245/35 R20 95Y

Nov 19, 2022

The side wall split on the outside of the tire and the tire deflated. I pulled to the side of the road. I have no spare because the tires are run flats. I tried to drive and within about 3 miles the tire shredded. The tread separated from the tire and made the car undriveable because the tire tread was hitting the wheel well. I was stranded with no spare. The rubber began melting and I was told by the tire shop fixing my car it fused to the rim. This tire was not made properly.

ENGINE

2 complaints

While driving on the highway the engine shut down and I needed to pull over and restart the car. The engine would restart but then stalled several more times while driving. No check engine lights were on before the vehicle stalled and upon restarting the car no check engine lights turned on. I have it at the dealership currently but they can't look at it until December because of their backlog of repairs.

POWER TRAIN,ELECTRICAL SYSTEM,ENGINE

1 complaint

The Engine Electrical harness is completely corroded after only 50,000 miles requiring a 4k+ repair. Oil leaking from the camshaft sensor pushed it way all throughout harness. There are no warnings as it will only be noticeable after doing routine maintenance OUTSIDE of the manufactures warranty. While driving you may lose complete power or slight power loss due to engine misfiring and low system voltage. Warranty company has denied my claim saying that it looks as if the car was in an accident with water damage but the car is pristine and accident free. This is happening to all Mercedes with magnetic camshaft solenoids after doing routine spark plugs. Any movement of the wires will cause damage to the corrosion and then electrical problems. This happened before with previous generations and they recalled the engine to put extensions between the sensors and harness. Unfortunately they did not do a recall for this generation even though the same problem is apparent!

UNKNOWN OR OTHER,ENGINE,FUEL/PROPULSION SYSTEM

1 complaint

Over the last couple of days, my car has displayed the "Engine Warning" message intermittently. I took this to the dealership for inspection and received the following fault code: P06DA00 - Inoperative Oil Pump Valve. For a car with low mileage, this could potentially be a car issue. The estimated total cost for labor and parts is over $5k. I think there are more cars affected.

There was smoke coming from from the engine compartment and spontaneous fire started while the car was at a stop light. The car was totally damaged. The car has less than 15000 miles driven. It is still under warranty. Information was sent to Mercedes-Benz USA with a certified mail and immediately via email from the dealership. Also was reported where the vehicle was stored if they wanted to investigate the engine. Benz USA just wanted me to fill out their standard report form. The towing company also told me that they had to tow another Benz not long ago from engine fire.

I was operating my car on a 4-lane highway early in the morning, conditions were sunny and weather was approximately 50 degrees. Without warning the panoramic sunroof on my E63S exploded with a loud pop and showered the interior of my car with glass. This was sudden and unprovoked by any outside object or force. Mercedes Benz USA has denied any responsibility via both dealership and choosing to be non-responsive to my MBUSA incident claim on the matter. In searching, this seems to be a common problem.

THE DOOR HINGES ARE DEFECTIVE. WHEN THE DOOR IS OPENED, IT CLOSES TOO QUICKLY. THE DETENTS DO NOT WORK. THEY DO NOT HOLD THE DOOR AJAR. THIS IS A LONG, HEAVY DOOR AND WHEN IT SLAMS SHUT ON YOUR LEG, ANKLE OR FOOT IT REALLY HURTS! THE ONLY WAY TO GET OUT OF THE VEHICLE SAFELY IS TO PUT YOUR FOOT AGAINST THE DOOR TO HOLD IT OPEN WHILE YOU EXIT. I BROUGHT THIS PROBLEM TO THE ATTENTION OF MB, WHO AGREED TO REPLACE THE HINGES ON THE DRIVER'S DOOR. ONCE THIS WAS DONE, THE DOOR WORKED FINE... FOR A MONTH. AND THEN IT SUFFERED THE SAME PROBLEM OF SLAMMING SHUT OR NOT STAYING OPEN. MB SUBSEQUENTLY REPLACED THE HINGE ON THE PASSENGER DOOR, WHICH IS HARDLY USED, SO I HAVE NO DATA FOR THAT. I HAVE WRITTEN TO MB ON SOCIAL MEDIA AND RECEIVED A RESPONSE THAT THEY WOULD "LOOK INTO IT." THIS IS A DANGEROUS CONDITION. IT MAKES ENTERING AND EXITING THE CAR PAINFUL AND STRESSFUL. MB NEEDS TO RE-ENGINEER THIS HINGE SO THAT IT WORKS AS IT IS SUPPOSED TO AND DOESN'T INJURE PEOPLE. LAST MONTH A FRIEND ARRIVED IN THE COUPE VERSION OF THIS CAR. AS HIS WIFE GOT OUT OF THE CAR, THE DOOR SLAMMED SHUT ON HER ANKLE. I TOLD HER TO CALL MB. THIS IS A SERIOUS PROBLEM WHICH COULD RESULT IN DEBILITATING INJURY. IT NEEDS TO BE CORRECTED.
