What 433 owners told NHTSA about the 2015 Mercedes-benz C-class Phev

I was driving my car was sputtering or trying to shut off while I press the gas and I let go of the gas and it catches and stayed on. I took it to the dealership and they said they found nothing wrong. May 3rd around 12pm im driving on the freeway and as im getting on the express lane going 60 it dies and I couldn't move the steering wheel and I slammed into a guardrail. After doing research my car (vin [XXX] ) had multiple recals from the fuel pump and steering wheel and the dealership never fixed or checked any recalls before selling it to me. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Car was parked in Garage with garage door open. Wife and I wanted to go biking and the bikes needed air in the tires. Pre-positioned one bike directly behind parked car and one parallel with the pneumatic air pump prepositioned to inflate the tires. Went to driver's side door and started car with foot on the brake and pushed the button. I then plugged in the adapter for the air pump into the cigarette lighter. The whole time the driver's side door was open and the car was not moving. I exited the car and walked backwards and knelt down abeam the left rear automobile tire to inflate the bike tire. I started the pump at the unit and started to connect the hose to the bike tire, I was then hit from behind by the car door which bent backwards as it passed over me in reverse at low speed. The bike may have saved me by creating a wedge to bend the door back and away from me. The car started down my driveway and dragged the bike parked behind it underneath wedged and sparking across the ground. I got some scrapes but jumped after the car and tried to stop it by trying to slow it with my weight and strength and it was not stopping or slowing. I was worried I may get run over a second time and let it continue to roll at low idle speed across the street and into the neighbor's car that was parked. I am positive the car was not moving after I started it and I didn't have my foot on the brake to engage the reverse function one I exited the vehicle. I believe that the car engaged in reverse once I started the air pump. Maybe it was a voltage or electrical spike. I have used this pump setup many times before to inflate the car's tires and my bike tires but never saw it do this before.

THE VEHICLE'S COLLISION PREVENTION ASSISTANT PLUS OPTION OFTEN DISPLAYS DURING DRIVING. THIS CAUSES THE CAR TO LOSE ACCELERATION AND PREVENTS YOU FROM ACCELERATING REGARDLESS OF HOW HARD YOU PRESS THE GAS PEDAL. THIS HAPPENS FOR NO APPARENT REASON AND OCCURS WHILE IN THE MIDST OF DRIVING, USUALLY WITHIN A BUSY INTERSECTION AND HAS ALSO HAPPENED TO ME SEVERAL TIMES WHILE DRIVING ON THE HIGHWAY. I AM VERY AFRAID TO DRIVE THIS VEHICLE. THE ONLY WAY TO CORRECT THIS WHEN IT OCCURS IS TO PULL OFF THE ROAD, SHUT THE CAR DOWN, AND RESTART THE ENGINE AFTER A FEW MINUTES. MY CAR WAS SERVICED ON 1/13/18 AND WHEN TESTED, NO EVIDENCE OF THIS WAS FOUND. SINCE THEN, THIS MALFUNCTION HAPPENED ON 1/14 AND AGAIN TODAY 1/15. THIS MALFUNCTION HAS THE POTENTIAL TO BE CATASTROPHIC. I'VE ADVISED THE DEALER THIS NEEDS TO BE SERVICED AND FIXED, OTHERWISE WE WILL BE ASKING FOR A NEW VEHICLE FOR THE REMAINDER OF THE LEASE. I AM VERY FEARFUL TO DRIVE THE CAR, ESPECIALLY WITH OUR TWO YOUNG CHILDREN.

I WAS MAKING A LEFT AT A STOP SIGN WHEN A DODGE DURANGO HIT ME HEAD ON AND FELL

NHTSA ODI 11043336

WHILE ACCELERATING FROM A STOP LIGHT FROM 0 TO SLIGHTLY OVER 40 MPH RECEIVED ERROR CODE OF ANTI COLLISION ASSIST INOPERABLE AND THE VEHICLE WENT FROM 40 MPH TO 0 LIKE I HIT A TREE. IT WAS NOT A SLOW SMOOTH MOTION OF SLOWING TO A STOP. THIS WAS A VIOLENT STOP THROWING ME FORWARD AND CAUSED MY SEAT BELTS TO ACTIVATE. IT SHOULD BE NOTED THAT THERE WAS NOT A SINGLE PERSON IN FRONT OF ME, BEHIND ME OR BESIDE ME. THIS WAS NOTHING SHORT OF A MIRACLE BECAUSE IF ANYONE HAD BEEN BEHIND ME, I WOULD HAVE BEEN REAR ENDED AND IF ANYONE HAD BEEN IN THE RIGHT HAND LANE I WOULD HAVE HIT THEM AS THE VEHICLE PULLED TO THE RIGHT VERY HARD WHEN IT MALFUNCTIONED. I TOOK THE CAR TO THE DEALER AND TOLD THEM I DID NOT WANT THE CAR BACK UNLESS THEY COULD DETERMINE WHAT HAD HAPPENED AND COULD PROMISE THAT IT WOULD NEVER HAPPEN AGAIN. UPON READING SO MANY COMPLAINTS ABOUT THE SAME LIFE THREATENING ELECTRICAL MALFUNCTION, THERE IS NO POSSIBLE WAY THAT MERCEDES BENZ IS NOT FULLY AWARE OF THE POTENTIAL FOR SERIOUS INJURY OR DEATH. I HAVE CALLED MB USA AND WAS TOLD THAT I WOULD NEED TO FILE A CUSTOMER INQUIRY. DONE. I PURCHASED THE VEHICLE IN APRIL 2016 WITH 7,200 MILES ON IT. I AM COMPLETELY TERRIFIED TO DRIVE THE CAR.
