WHILE VEHICLE WAS STATIONARY IN GARAGE, WE BEGAN NOTICING A PROFUSE GAS/FUEL SMELL. IT BECAME INCREASINGLY STRONG IN AND OUT OF THE VEHICLE.

THE VERY DAY I BROUGHT MY CAR HOME FROM A USED CAR PURCHASE, THE MOMENT I PULLED IN MY DRIVEWAY TO PARK, THE MESSAGE CENTER SAID, " SOS SERVICE NOT ACTIVATED" IN A WARNING IN THE CENTER CLUSTER. IT WOULDN'T GO AWAY AND I DIDN'T KNOW WHAT TO DO, SO I PUSHED THE SOS BUTTON AND MB ASKED ME, " WHAT IS YOUR EMERGENCY ?" I APPOLOGIZED AND EXPLAINED THAT I HAD RECEIVED A WARNING MESSAGE ON MY DASH. THEY ENDED THE CALL AND I TURNED OFF THE CAR. I RESTARTED THE CAR AND THE WARNING WENT AWAY. THIS WAS ON FEB 1, 2018 AT 4:38 P.M.

Car looses communication with the Electronic Ignition System (keyless system) and while rolling to a stop light, slams the car into park while still rolling. It also will throw itself into park while first accelerating - almost causing the car following me to crash into my rear end.

I brought the car to my Mercedes dealer for a State required safety and emissions inspection. It passed but they said the rear brake line were rusted and needed replacement at a cost of $2546.00. This model and numerous others were recently provided an extended warranty for rusted subframes. This is a $5-$7K repair. They do not cover the brake lines or include them as part of the repair. The sub-frame rust from the inside out so it is not initially obvious of impending failure. There is a pending class action lawsuit against MBUSA that mentio…

After the Mercedes dealer replaced the corroded rear sub frame under the 20 year extended warranty, my brake line failed so I took it back & found out that the brake lines were corroded. I paid nothing for the subframe since it was under the warranty but I ended up paying $4114 to replace the corroded brake lines. The dealer should have checked for corrosion while the subframe was out of the car, especially since this is a known issue. The parts were only $380 and $3800+ was labor. My brakes completely failed while driving on Christmas Eve. I t…

It has been confirmed by a glass company that the car has an improper seal/bonded windshield. The windshield is the original and the car has never been in an accident. A few years ago, i noticed a rattling that I was unable to identify. This was reported during one of the regular maintenance services but the sound was not replicated (as it would happen more often when cold). Recently, the sound has gotten worse, and I had a water leak so I suspected the windshield. As I have already stated the problem was confirmed, and you can liter…

ON MARCH 8 2020 I WAS DRIVING MY 2014 MERCEDES BENZ CLS550 STRAIGHT ON THE FREEWAY WHEN MY SUNROOF EXPLODED, GLASS SHATTERING EVERYWHERE. GLASS HIT MY FACE AND WENT DOWN MY BACK AND CUT MY HANDS.

THE FRONT OF THE SUNROOF WAS INDENTED INWARD AND GLASS WAS ANGLED OUTWARD AS IF IT HAD EXPLODED FROM THE INSIDE OUT. I RESEARCHED ONLINE TO FIND THAT THERE WAS A RECALL FOR 760,000 MERC…

The steering wheel power adjustment function stopped working. The steering wheel went to the topmost position and got stuck there. It still telescopes in and out, but the up and down function stopped working, and it's stuck at the highest position and won't move down. The car has 52K miles and was not in an accident. Due to the strange position of the steering wheel, it is more difficult to control the car. There were no warning lights about this.
