I bought my vehicle into Mercedes Benz for a recall related to water collection in spare tire well which can cause a fuel pump control malfunction, NHTSA recall # 22V955. A few days ago, my vehicle could not start and I found water in my spare tire well. My OBD scanner tells me it is related to the fuel pump. I informed Mercedes Benz and they would not fix it. Obviously the work performed did not correct the recall. I'm writing here hoping I can get connected to the right channel to get this resolved as my vehicle is currently unusable. Thanks.

I am writing in regards to my 2014 ML 350 Suv. The check engine light came on and upon taking it to the mercedes dealership, I was told the issue is that the camshaft adjusters have failed and need to be replaced. The cost quoted is over $11,000 to repair. Upon further investigation I found reports on multiple lawsuits for the Mercedes C series for the same year (2012-2014) that resulted also in a recall whereby customers were given a recall to replace at no charge the camshaft adjusters up to 120k miles. My car only has 83k and I am told by two independent mechanics that the camshaft adjuster should not be failing like this and that this has been an ongoing issue with Mercedes. The safety issue is that I am told by independent mechanics that what could happen over time is that I could be driving and the entire engine/power just shuts off. This could even happen at high speeds on the highway. The mercedes dealer tells me there is no safety issues that could result from camshaft adjuster problems which doesn't appear to be true as per the other independent mechanics. I request further investigation into this issue because as per the independent mechanics its the "same engine" as the 2012-2014 that are under the recall . I'm requesting a recall on this for my car that Mercedes pays for. This should not be failing especially in a car with only 83k on it . If the C series 2012-2014 received recall on this part then I also think my ML 350 should be covered. Mercedes customer service tells me they cannot pay for the repair, they said I could file complaint for recall through NHTSA Thank you .

Campaign no. 2012070002 SB-10048279-4718 Same solenoid leaking issue onto wiring harness for my 2014 Mercedes ML350 need this to be initiated because mercedes is at fault for not fixing this issue in 2006-2012 now still issue in 2014.
Other that other 2014 ml350 have a recall for oil leaking from the reserve. Seems like my vehicle is affected by this issue as well, oil leak when low

IN MY NEIGHBORHOOD APPROACHING A STOP SIGN ABOUT 20 YARDS AWAY. THE CAR ALL OF A SUDDEN ACCELERATED AT A HIGH RATE OF SPEED. I WAS GOING TOO FAST TO MAKE THE RIGHT TURN AND THE BRAKES DID NOT STOP THE CAR. I ENDED UP RUNNING THROUGH THE STOP SIGN UP AN INCLINE AND INTO THE WOODS HITTING MULTIPLE TREES BEFORE COMING TO A STOP. THIS CAUSED OVER $18,000 DAMAGE TO THE VEHICLE (NOT INCLUDING DAMAGE TO THE UNDER CARRIAGE). NOT ONLY WAS THIS PRETTY FRIGHTENING BUT WHAT COULD HAVE HAPPENED IF I WASN'T IN MY NEIGHBORHOOD WHEN THIS TOOK PLACE COULD HAVE KILLED SOMEBODY. IT REALLY SHOOK ME UP. THANK GOODNESS THERE WERE NO KIDS AT THE BUS STOP. I WAS ALSO SURPRISED THAT THE AIR BAGS DID NOT DEPLOY. THE INSURANCE COMPANY TOTALED THE CAR SO NO ONE REALLY SEEMS TOO CONCERNED ABOUT THE CAUSE OF THE UNINTENDED ACCELERATION THAT TOTALED MY CAR WHILE DRIVING IN MY OWN NEIGHBORHOOD! THIS SHOULD NOT HAVE HAPPENED. I HOPE SOMEONE WILL CARE ENOUGH TO TRY AND DETERMINE WHAT HAPPENED SO THIS DOESN'T HAPPEN TO SOMEONE ELSE.
TAILGATE OPENS WITHOUT BEING ACTIVATED. WHEN BACKING OF GARAGE TAILGATE CAME OPEN AND HIT GARAGEDOOR OPENING, CAUSING SHEETMETAL TO BEND. THIS HAS HAPPENED SEVERAL TIMES.
REAR TAILGATE OPENED WITHOUT BEING OPERATED AS I WAS ENTERING GARAGE. REAR WINDOW HIT GARAGE TRIM AND BROKE. THIS HAD HAPPENED BEFORE DRIVING DOWN THE STREET.
