2016 Mercedes-Benz E-Class UNKNOWN OR OTHER

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.

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.

PANORAMIC ROOM IS MAKING A LOUD POPPING NOISE LIKE THE GLASS IS COMING APART FROM THE CAR. IT HAPPENS WHEN I MAKE A TURN OR GO UP AN INCLINE. THIS STARTED HAPPENING FOR NO REASON AND IS CONSISTANT. I HAVE READ ONLINE FORUMS WHERE ALOT OF PEOPLE ARE COMPLAINING OF THE EXACT ISSUE.

THE AIR FROM AC VENTS SMELLS MOLDY AND OF MILDEWY ODOR.

PANOROMIC ROOF. ROOF MAKES CREAKING NOISE WHEN TURNING OR DRIVING ON UNEVEN OR ROUGH ROAD. NOISE SEEMS TO BE COMING FROM THE REINFORCEMENT PLATE BETWEEN PANOROMIC ROOF JOINT. THIS IS VERY NOTICIABLE, LUBING THE SUNROOF TRACK OR POSITON OF SUNROOF(CLOSE OR OPEN) DOES NOT REDUCE NOISE OR ISSUE.

THE CAR UNINTENTIONALLY ACCELERATES WHEN STARTING FROM A STOPPED POSITION. THE ENGINE REVS UP THEN THE CAR LURCHES. THIS HAS HAPPENED SEVERAL TIMES WHEN TRYING TO PROCEED FORWARD AND BACKWARD. THE CAR WAS BROUGHT IN FOR SERVICE BUT NO ISSUES WERE FOUND AND THE CAR RETURNED AS WAS.
