2014 Mercedes-Benz E-Class UNKNOWN OR OTHER

I received a letter from Mercedes stating there was concern over 2010 to 2014 (est) that should be checked after 10 years. I can not find that letter. I have a 2014 EClass 350 model. Can you please tell me what is was? Thanks

The subframe of my vehicle is prematurely rusting, creating the risk of unpredictable, catastrophic failure. This failure could cause loss of control of the vehicle and severe injury and/or death. The vehicle is available for inspection. My independent mechanic is aware this is a known problem with these vehicles, and has been monitoring mine, and his mother’s, for damage. By August 2023, my vehicle will fail Pennsylvania’s safety inspection. The vehicle has not yet been inspected by any entity other than my mechanic. There is no warning, from any system of the vehicle, of the deterioration, extent of deterioration, or impending failure of the subframe.

Driver's side rear subframe has rusted to the point metal is split open. This was found during routine maintenance service at dealer. While braking the vehicle pulls to the left. If not replaced, wheel can fall off.

The 2014 E350 4matic was diagnosed by the Dealer with a cracked rear subframe. When I questioned that is this common with a 2014 model EClass they were not sure. Calling MB USA they felt there weren't any complaints. When I called 9 different dealers in the USA looking for a NEW subframe for the E-Class, the common response was we are receiving many calls about replacing the subframe due to issues / cracked frame/rust, etc. They were all surprised and felt this is odd that this model would have so many subframe issues. MBUSA denied any issues as far as any structural issues. Very odd that my 2014 with approx 100k miles (garaged all the time) has subframe issues.

The Rear Subframe Unit of this 2014 E-Class E212 is diagnosed as rusted and rotted out on this 8 year old vehicle. The poor quality of this part from Mercedes Benz is known to be an underlying, hidden risk factor to the stability of the vehicle. This is a hidden/underlying area of the vehicle, not visible to the driver/owners, that without cause, can break free from the main frame structure of the vehicle and create a stability factor when cornering and braking, causing swaying of the rear and owner panic when abruptly stopping. I had this vehicle serviced at Catonsville Mercedes-Benz since I purchased the vehicle on April 14, 2017. On my last visit on December 19, 2019 having only 40,051 miles. No physical evidence know to me during this inspection. The vehicle has been hardly used. My next service was done on July 28,2022, having only 49,250 miles. That's just 9,299 miles and just over 2 years later, no harsh weather conditions, and the dealership has confirmed that this subframe has rotted out and rusted nearly thru. The service writer informed me that this is a serious condition that can break apart and lead to a very serious accident. Depending on certain driving conditions, if this breaks apart unknowingly, can be catastrophic. Mercedes Benz advertised greatly the ultimate safety features of its products, only to be realized, that it has used poor quality galvanized steel on a major structure of its framework to save cost. Mercedes provides a 3 year/36,000 mile and a 5 year 50,000 mile powertrain warranty which neither covers this. Galvanized steel has a life expectancy of 6 to 8 years resulting in deterioration, which Mercedes knowingly intends to pass this repair cost to the owners. This vehicle was inspected by a certified authorized Mercedes Benz dealership. Warning lights, message sensors are not installed on this part. No other parts surrounding this component show any signs of rust, rot or deterioration. I feel unsafe to drive or place family within.

AFTER DRIVING FOR 1 HOUR, BACK SEAT SHELF SPEAKER MADE A LOUD POPPING AND HUMMING NOISE AND EMITTED A STRONG BURNING SMELL. TRUNK OPENED AND CONFIRMED SMOKE COMING FROM REAR AMPLIFIER, STRONG SMELL OF PLASTIC MELTING AND SPEAKERS WERE TOO HOT TO TOUCH. DISCONNECTED AMPLIFIER FROM BATTERY AND TOOK VEHICLE TO DEALER WHO CONFIRMED. DEALER RE-HOOKED AMPLIFIER TO BATTERY, CONFIRMED THAT AMPLIFIER WAS INDEED SMOKING AND SPEAKERS WOULD NEED REPLACING AS WELL. VEHICLE ONLY HAS 57,750 MILES AND IS OUT OF WARRANTEE. LOCAL DEALER MAINTENANCE REPRESENTATIVE AGREED THAT A VEHICLE WITH SUCH LOW MILEAGE SHOULD NOT BE CATCHING FIRE BUT DEALER WOULD NOT COVER COST OF REPAIR.

I WAS EASING INTO MY GARAGE AND SUDDENLY THE CAR ACCELERATED AND THE BRAKES WOULD NOT WORK. *TR

MY 2014 MERCEDES-BENZ E350S WAGON HAS KNOWN DEFECTIVE WOOD TRIM THAT HAS FADED WITHIN 5 YEARS AND HAS BECAME CLOUDY, AND DETERIORATED OVER TIME DUE TO INADEQUATE UV RAY PROTECTION. THERE HAVE BEEN SEVERAL LAW SUITES FOR MODELS 2009 TO 2016. THE DEALER AND MERCEDES-BENZ USA HEADQUARTERS TOLD ME THAT THAT THE WOOD WOULD HAVE TO BE REPLACED AT MY COST. THIS IS A KNOWN DEFECT AND THE DEALERS HAVE BEEN TOLD TO SELL CARS AND DON'T MENTION THAT THE WOOD WOULD FADE OVER TIME.

PRE SAFE COLLISION WARNING- THE LIGHTS BEEPS WHEN THERE IS NOTHING IN FRONT OUR NEXT TO ME. IT IS VERY DISTRACTING. I TOOK THE CAR IN TO THE DEALER THREE TIMES ALREADY FOR THE SAME PROBLEM. NOW IT IS STILL BEEPING. THERE NEEDS TO BE A RECALL BECAUSE IT IS VERY DISTRACTING AND CAN CAUSE AN ACCIDENT.

WHILE PARKED FOR ABOUT 30 MINUTES AFTER A SHORT DRIVE SMOKE BEGAN COMING OUT FROM THE FRONT GRILL, FROM UNDER THE HOOD, AND FROM WHEEL WELLS. FIRE DEPT. WAS CALLED IMMEDIATELY. THE FIRE STATION WAS NEXT TO THE PARKING LOT WHERE THE CAR WAS PARKED SO THEY ARRIVED QUICKLY. THE INSURANCE COMPANY DETERMINED THE CAR WAS A TOTAL LOSS..

PRE SAFE COLLISION WARNING SYSTEM FAULT, WITH REPEATED FALSE ALERTS WHILE VEHICLE IN MOTION, WITHOUT ANY NEARBY VEHICLES OR OBSTRUCTIONS AHEAD. FALSE ALERTS CAN RESULT IN SUDDEN BRAKING RESPONSE, WHICH CAN BE A HAZARD TO FOLLOWING OR SURROUNDING TRAFFIC.

DRIVER SIDE DOOR STARTED TO SMELL OF FIRE ON 4/10/2017 @ APPROXIMATELY 1600 LESS THAN 1/4 MILE FROM HOME. PULLED CAR INTO DRIVE AND SHUT ENGINE DOWN, IMMEDIATELY CONTACTED MERCEDES-BENZ OF TAMPA. REP ASKED ME TO BRING CAR IN TO SERVICE DEPT. DID SO.
