2014 Mercedes-Benz C 300 Problems

I purchased my vehicle from the Mercedes Benz Dealership and received a recall letter in the mail stating that driver side deployment may occur. After receiving notice I brought the car to the dealership to get the recall repaired. I've been driving around with a false sense of security believing that this issue was repaired. However, recently, while I was driving the driver side airbag unexpectedly and abruptly deployed and injured me. This is a major safety concern and car owners should be notified and made aware that the issue can still occur after the recall was repaired. I contacted Mercedes Benz and they did not issue any additional notices to inform customers of possible recall issue reoccurring due to manufacturer defects even after the repair was made. Additionally, I believe the driver side Takata airbag/inflators may have also been defective because of the injuries I incurred from the forceful explosive eruption of the airbag. MBUSA Campaign Number 2017120024 NHTSA Recall Number 17V627 Recall Start Date January 18, 2018 Recall Reported Date October 16, 2017 Component(s) 1709P46C62 Daimler AG (DAG), the manufacturer of Mercedes-Benz vehicles, has determined that certain MY12-17 C-Class, E-Class, E-Class Coupe vehicles (204, 207, 212 platform) have insufficient electrical grounding in the steering column components. In rare instances, if the steering column module is exposed to an electrostatic discharge, and if the steering column module clock spring is broken (due to wear), this could lead to an inadvertent deployment of the driver airbag. An inadvertent driver airbag deployment may cause a risk of injury to the driver and might increase the risk of a potential crash. A broken clock spring will illuminate the SRS warning light as well as display a warning message in the instrument cluster. An authorized Mercedes-Benz Dealer will install a sufficient ground to the steering column, and a protective ring to the steering column module.

While I was driving my car the driver side airbag abruptly deployed. The airbag inadvertently deployed; the car did not crash into anything to cause the airbag to deploy. When the airbag erupted it caused injury to my head, face, hand, arm and wrist. I believe the airbag is defective because I have lacerations on my face possibly due to sharp objects ejecting from the airbag and the impact as well as excessive smoke and fumes emitted after the fact. I believe there might be a manufacturing defect in the airbag because it seemed as if it exploded with excessive force causing harm to myself as well as inadvertent eruption. There have been some recalls issued on the motor vehicle and I did take the vehicle to the Mercedes car dealership to get all of the recalls repaired, however this incident occurred after the repairs were made at the dealership.

To Whom It May Concern, I am seeking assistance regarding my 2014 Mercedes-Benz C-300, VIN [XXX] . I repurchased this vehicle from the London Nissan Dealership on [XXX]. It currently has about 120,000 miles, and I have driven an additional 15,000 miles in the past two years. Less than three months after purchase, I took the car to a Mercedes-Benz dealership in Knoxville, TN, for repairs on May 16th. Now, my vehicle is at James Motor Company in Lexington, KY, where they diagnosed a faulty steering column that needs replacement at a cost of $1,630.00. I have already taken this car to the dealership twice for issues in under two years. The problems began when the vehicle wouldn’t start one morning; the steering column was locked despite a fully charged battery. This failure could have led to a serious accident, especially since I drive frequently for work and school. There were no warning signs prior to this incident. The dealership has confirmed the steering column issue and can provide inspection upon request. I also have a list of parts needed for the repair available. Given the nature of this malfunction, I believe it warrants a recall. Thank you for your attention to this serious matter. I look forward to your prompt response. Sincerely, [XXX] [XXX] [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The left rear subframe separated from the main frame causing the car to pull to the left when braking. I had an episode where I was stopping for a traffic light and the car started fishtailing and I almost lost control of the car. Following this episode, I took the car to a mechanic who advised me that the car was unsafe to drive. My mechanic also told me that he has repaired a number of these vehicle with the same problem, and that Mercedes Benz has extended their warranty from 4 years 50,000 miles to 20 years unlimited mileage. They did the extension after someone filed a class action suit in Georgia about the problem. The vehicle is presently at a Mercedes dealer awaiting the new subframe.

Rotted rear sub frame due to poor design retaining water

The contact owns a 2014 Mercedes-Benz C300. The contact stated that an unidentified recall was previously completed on the vehicle; however, the recall remedy failed to prevent the failure from occurring. The contact stated that while driving at undisclosed speeds, the steering wheel locked. No warning light was illuminated. The vehicle was towed to a local dealer, where it was diagnosed and determined that the electronic steering lock and the TRP needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure, but no assistance was provided. The failure mileage was approximately 158,000.

The driver's side door handle broke impossible to open door from inside if there was an accident. I have been told that this is a common problem with my car, and that it cost 1600.00 to replace repair at the dealer. This is such a common problem that there are after market kits to repair the broken handle for 20.00, but including labor the repair is $500.00.

Leaving my home from my driveway and driving about 15 feet I heard a loud pop from my backseat area and noticed my Headrest on drivers side deployed without any reason. The airbag right/left malfunction light showed on my dash saying service required. Mercedes benz Dealership said they never heard of this. The dealership Removed old headrest and replaced with a new one , reset malfunction light and a fuse. Price was enormous.

The driver's side interior door handle became disengaged as I was trying to open the door so I was momentarily trapped inside. If I had been in a situation where I had been in an accident and needed to get out quickly, or the car had been on fire, or I was stalled on the train tracks, this could have been a serious incident. When I googled this, it sounds like this is a very common occurrence in Mercedes. There was no warning that this was going to occur - everything seemed secure before this happened. I have taken it to a service center for a very expensive repair as they have to remove the door panel, replace/reattach the part and put the door panel back.

TL* THE CONTACT OWNED A 2014 MERCEDES-BENZ C350. THE CONTACT STATED THAT WHILE DRIVING AT APPROXIMATELY 15-30 MPH, THE VEHICLE INDEPENDENTLY ACCELERATED. THE CONTACT STATED THAT HE WAS UNAWARE OF HOW HIS FOOT ENDED UP UNDER THE ACCELERATOR PEDAL. THE VEHICLE WAS THEN INVOLVED IN A FOUR VEHICLE COLLISION. THE CONTACT STATED THAT ALONG WITH HIS WIFE WHO WAS IN THE CAR AT THE TIME, SHE WAS INJURED ALONG WITH ONE OTHER OCCUPANT OF ONE OF THE OTHER VEHICLES. IT WAS UNKNOWN WHERE THE WIFE WAS SEATED. MEDICAL ATTENTION WAS SOUGHT SEVERAL DAYS AFTER THE COLLISION BY THE CONTACT AND HIS SPOUSE. A POLICE REPORT WAS FILED. THE VEHICLE WAS TOWED TO A TOWING LOT. AAA WAS ABLE TO RETRIEVE DATA FROM THE VEHICLE DATA RECORDER. THE CONTACT WAS INFORMED THAT A COMPREHENSIVE REPORT COULD BE ATTAINED BY EQUIPMENT THAT ONLY THE DEALER OR MANUFACTURER POSSESSED. THE VEHICLE WAS NOT REPAIRED. THERE WAS NO DIAGNOSTIC CHECK OR INSPECTION PERFORMED ON THE VEHICLE. A DEALER WAS NOT CONTACTED. THE VEHICLE WAS DESTROYED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 34,366. *JS

I WAS STOPPED IN FRONT OF MY GARAGE (WAITING FOR THE DOOR TO GO UP). WHEN I LIGHTLY PRESSED ON THE GAS PEDAL TO PULL IN, THE ENGINE ROARED AND THE CAR SUDDENLY LEAPED FORWARD AT A VERY HIGH RATE OF SPEED, GOING THRU MY DETACHED GARAGE WALL. THE ACCELERATOR PEDAL STUCK AND I COULD NOT GET THE CAR TO STOP. I HAVE PULLED INTO THIS GARAGE THOUSANDS OF TIMES AND KNEW THIS WAS THE CAR. SLAMMING ON THE BRAKES COULD NOT STOP THE CAR BECAUSE IT WAS ACCELERATING TOO QUICKLY. HITTING THE BRICK FACADE OF THE CONDOMINIUM, BEYOND THE DETACHED GARAGE WAS THE ONLY THING THAT STOPPED THE CAR. NO AIRBAGS DEPLOYED, WHICH I THOUGHT THEY SHOULD HAVE BECAUSE OF THE IMPACT. EVEN THOUGH I ONLY TRAVELED APPROXIMATELY 30 FEET, THE CAR ACCELERATED SO QUICKLY, IT TOTALED THE CAR. THE CAR IS CURRENTLY UNDER RECALL AS OF NOVEMBER 2017, FOR A STEERING COLUMN ISSUE, WHICH INCLUDES IMPROPERLY GROUNDED COMPONENTS AND THE STEERING COLUMN CLOCK SPRING BEING BROKEN ISSUE RELATED TO THE AIRBAGS DEPLOYING WHILE DRIVING THE CAR. I HAVE TIRED SEVERAL TIMES TO HAVE THE CAR REPAIRED AND HAVE BEEN TOLD THE MERCEDES DEALERSHIP STILL DOES NOT HAVE THE PART. PER THE DEALERSHIP AND MERCEDES, I WAS ADVICED I WOULD RECEIVE A LETTER WHEN IT WAS AVAILABLE. I PURCHASED THE CAR USED AND HAVE SINCE FOUND OUT SINCE THIS IS THE THIRD RECALL ON THIS VEHICLE. I BELIEVE IT HAD TO BE SOMETHING WITH EITHER THE ACCELERATOR AUTOMATICALLY ENGAGING. IT WAS ALMOST LIKE THE CRUISE CONTROL QUICKED IN. SINCE IT IS UNDER RECALL FOR THE STEERING WHEEL RELATED ISSUE, I DON'T KNOW IF IT AFFECTED THE CRUISE CONTROL AND CAUSED THIS TO HAPPEN.

Completely rotted & rusted sub-frame. Caused braking/stability/steering issues and was completely undriveable. Cost $2300 to fix, another $1000 for car rental as well as lost time at work. There have also been many reports of this problem with other drivers of the same model of vehicle. NO warning lamps or messages whatsoever, only knew the level of damage once I brought it into auto shop.

The wheel is not tilting up or down. It's stuck I. Top. It will just go out and in but stuck in the top position. This is a safety issue especially with airbags. The problem have been reported to dealers . It's a defective system

The intake manifold blew on my car while it was off overnight and I took it to the Mercedes dealership to have it fix and the next day I got it back after it was repaired the same problem happened again when I went to unlock my car I heard a bang and smoke coming from the engine

Parked the car, did something, came back and car did not start. Key in, no crank, no start, no steering. No lights on the dash, no gear shifting, can’t roll the windows up. All out of nowhere. Think it’s a problem with the Electronic Steering Lock.

WHEN THE OUTSIDE AIR INTAKE IS COVERED WITH SNOW OR ICE IT WILL NOT ALLOW OUTSIDE AIR INTO THE HVAC SYSTEM. THIS CAUSES THE FRONT WINDOW DEFROSTER TO NOT BE ABLE TO BLOW AIR ON THE WINDSHIELD TO CLEAR THE WINDSHIELD. THIS IS A VERY DANGEROUS DESIGN FLAW ON BEHALF OF MERCEDES BENZ. IF HOT WATER IS POURED OVER THE OUTSIDE AIR INTAKE SCREEN THE BLOWER WILL OPERATE PROPERLY, BLOWING HOT AIR TO DEFROST THE FRONT WINDSHIELD. ONLY HAPPENS IF THE CAR IS OUTSIDE WITH SNOW OR ICE BUILDUP TO BLOCK AIRFLOW INTO THE HVAC SYSTEM. DEFROSTER WILL WORK PROPERLY IF NO SNOW OR ICE IS COVERING THE AREA.

AT FIRST THE CAR WOULD HAVE A LIGHT TICKING OR KNOCKING NOISE AFTER A 15-20 MINUTE RUN ON THE HIGHWAY AT 70 MPH. LAST WEEK, FRIDAY EVENING, I STARTED SMELLING SMOKE SOMETHING LIKE PLASTIC, ENOUGH TO MAKE YOU SEARCH FOR THE SOURCE. IT SEEM AS THOUGHT THE SMOKEY SMELL IS COMING FROM THE INSIDE BUT AFTER OPENING THE DRIVERSIDE DOOR THE BURNING SMELL IS COMING FROM UNDER THE CAR. ON YESTERDAY, MONDAY, FOUR DAYS SINCE I FIRST SMELL OF SMOKE, WHICH IS CONSISTENT NOW AND LOOKED AT BY A MECHANIC WHO SAID RUNNING OVER A PLASTIC BAG IS THE POSSIBLE PROBLEM. SOUNDED LOGICAL UNTIL A FEW HOURS LATER AFTER A 25 MILE HIGHWAY RUN AT 70+MPH THE CAR WAS SHAKING AND STUGGLING TO STAY ON. THE SMOKEY SMELL WAS ELEVATED AND THE POWERTRAIN LIGHT WAS ON. CALLED THE MECHANIC WHO TOLD ME TO PULL OVER, WAIT AND RESTART THE CAR. NOW I'M AFAID TO DRIVE THE CAR WHICH IS SCHEDULED FOR A DIAGNOSTIC TEST TODAY, TUESDAY, MAY 17, 2016. WHERE THERE'S SMOKE THERE'S FIRE,

RE: CONTINENTAL PROCONTACT (FRONT) 225 45 R17 AND (REAR)245 40 17- ON SEPTEMBER 11, 2014 AT 306 MILES TIRE DISPLAYED BULGE NEXT TO "C" OF CONTINENTAL OF FRONT PASSENGER SIDE TIRE. THE CAR WAS SITTING FOR A WEEK NOT BEING DRIVEN WHEN THE BULGE APPEARED. I WAS NOT GOING TO DRIVE ON A MAJOR HIGHWAY AND CHANCE A BLOW OUT ACCIDENT. CAR WAS TOWED TO MB FREEHOLD WHERE THEY TOLD ME I WENT OVER A POTHOLE. I DIDN'T BELIEVE THAT TO BE THE CASE BUT I WAS AT THERE MERCY. TIRE WAS REPLACED AT MY EXPENSE AND I WAS ABLE TO DRIVE HOME; NOVEMBER 8,2014 THE NEW REPLACED TIRE OF THE SEPTEMBER 11, 2014 EVENT( FRONT PASSENGER SIDE TIRE) HAD A BLOW OUT WHILE DRIVING 25 MILES AN HOUR. THE CAR WAS GARAGED FOR APPROX 2 WEEKS AND NOT DRIVEN, THEN FOR 2 DAYS DRIVEN LOCALLY TO DO ERRANDS, THEN DRIVEN ON HIGHWAY AN HOUR TO MY DESTINATION AND AN HOUR BACK WHEN IN MY NEIGHBORHOOD AT 25 MILES PER HOUR THE CAR WAS OUT OF CONTROL AND THE REPLACED TIRE BLEW. THE MALFUNCTION LIGHT WENT ON- IT WAS DARK AND I HAD NO CHOICE THEN TO DRIVE MY HOUSE....THE WHEEL WHICH WASN'T SCRAPED BEFORE IS NOW SCRAPED... CAR DOESN'T ACCELERATE BUT JERKS AND JOLTS WHEN TRYING TO PASS OR CHANGE LANES/DANGEROUS ON HIGHWAYS. *TR
