During hard acceleration the high-pressure fuel pump fails. I've never had to replace this part on any other car that I have owned. When I research the part for this car, I reviewed many forums and articles complaining about the failure of the high-pressure fuel pump on the Mercedes c250 sport or similar chassis. The vehicle performs normally until there is hard acceleration; then the engine light comes on. This causes the car to lose acceleration power and slows the car down significant and can be dangerous especially if driving on a freeway or highway. The failure of the part has been reported to occur as early as 30k miles.

While trying to pass big rig on freeway my car went into lymph mode and stalled causing the car behind me to brake and almost caused an accident. My engine light came on & after getting it checked out I retrieve the following code P0002. After doing some research it appears this is an ongoing issue with this year and model of car.

2012 C250 has a known defect with high pressure fuel pump. I personally have had an intermittent issue where vehicle will unpredictably stop working under heavy throttle and enter limp mode as the computer throws a fault code. This results in loss of power after the code making vehicle unpredictable and dangerous in passing situations. It leaves you stranded in the passing lane with oncoming traffic with a vehicle that will not accelerate. I have submitted a request multiple times with Mercedes benz corporate who has declined my submission. This issue has been ongoing since 2016. They have offered an extended warranty on the vehicle 10 years and 120,000 miles as they know there is a defect. It is dangerous and needs to be covered for all of the affected vehicles.

When accelerating to pass a vehicle the check engine light comes on and there is loss power. When this happens there is a huge potential of a crash. The car has to be shut off to try and reset this. When you are on the frwy this puts life at danger. The code is a p002 and if you research it Mercedes is aware of this and is most likely a defective high pressure fuel pump problem that needs replacing but there have been no recalls. I have looked it up on you tube and has been on ongoing issue with no recalls as of yet. I am taking my car to dealer on 11/15/2021 for this issue which they will charge me for even though its a safety issue

WHEN ACCELERATING TO PASS ON HIGHWAY CAR SUDDENLY GOES INTO LIMP MODE AND LOSSES POWER THIS IS DANGEROUS AT 70 PLUS MILES PER HOUR, ECM CODE READS P0002 HIGH PRESSURE FUEL REGULATOR FAILURE, CHECK ENGINE LIGHT WILL STAY ON UNTIL CAR HAS BEEN SHUT OFF FOR LONGER THAN TEN MINUTES OR IF YOU HAVE A SCANNER YOU CAN ERASE CODE AND DRIVE THE CAR NORMAL, NO PASSING. THIS HAS ALSO HAPPEN PULLING OUT FROM A STOP LIGHT CAR HAS BUCKLE WITH IMMEDIATE POWER LOSS AND WILL ONLY CREAK UP IN LIMP MODE JUST ENOUGH TO GET YOU HOME. I AM A WELL SEASON MECHANIC WITH OVER 20 YEARS EXPERIENCE AND THIS IS ABSOLUTELY DANGEROUS. PLEASE DON'T WAIT UNTIL SOMEONE GETS HURT OR KILLED BY THIS WHICH IS A KNOWN ISSUE GOING BACK BEFORE 2012. THIS HAPPENED 3 TIMES THIS AST WEEK AND TODAY.

I HAVE BEEN HAVING ISSUES WITH MY VEHICLE SINCE I PURCHASED IT. STARTING WITH ME NOT HAVING ENOUGH POWER FROM A START, IN AN ATTEMPT TO GAIN ENOUGH POWER TO DRIVE AT A SAFE SPEED FROM THE START, AS IF THE VEHICLE LAGS & NO MATTER THE GASOLINE OR SERVICE, THE PROBLEM NEVER CORRECTS. WHEN I'M TRYING TO GAIN SPEED TO MAINTAIN WITH THE FLOW OF TRAFFIC SAFELY THE VEHICLE LAGS NOTABLY BEFORE GAINING SPEED. I'M NOW HAVING TO REPLACE THE ENGINE BC THE OIL COOLANT HOSE BURST WHILE I WAS DRIVING ON THE HIGHWAY WITH MY CHILD IN THE CAR. MY CHECK ENGINE LIGHT ACTIVATED BUT THE ONLY NOTICE DISPLAYED ON THE DASH WAS THE ENGINE COOLANT WHEN IT WAS LOW. WHEN THE HOSE BURST WHILE I WAS DRIVING ABOUT 60MPH I HEARD A POP SOUND UNDER THE HOOD, SAW SMOKE COMING FROM THE EXHAUST, THEN A CLANKING NOISE UNDER THE HOOD THAT GOT LOUDER & LOUDER UNTIL I WAS ABLE TO PULL OFF OF THE HIGHWAY, & THEN I NOTICED A VERY LARGE AMOUNT OF OIL ON THE GROUND THAT LEFT A TRAIL ALONG THE GROUND FROM MY VEHICLE. THAT WAS VERY DANGEROUS AS MY VEHICLE LOST POWER DURING THAT INCIDENT. I'M TOLD BY THE MECHANIC, THE ENGINE HAS TO BE REPLACED. THIS HAPPENED WITHOUT A WARNING. THE MERCEDES BENZ IS SUPPOSED TO BE A SAFE & RELIABLE LUXURY VEHICLE & NOT A NIGHTMARE TO HAVE FOR THE OWNER.

I FIRST NOTICED THIS PROBLEM ABOUT 2 YEARS AGO. I WAS ON THE HIGHWAY GETTING READY TO PASS A BIG RIG. ABOUT 2 SECONDS AFTER I EXCELERATED I NOTICED THAT I LOST POWER TO THE ENGINE AND THE CHECK ENGINE LIGHT TURNED ON. I KEPT MY FOOT ON THE PEDAL HOPING TO REGAIN POWER TO PASS THE BIG RIG. I HAD NO SUCH LUCK. SHORTLY AFTER I HAD VEHICLES BEHIND ME HAVING TO SLOW DOWN BECAUSE MY CAR WOULDN'T EXCELERATE TO THE DESIRED SPEED. I FINALLY MADE MY WAY OUT OF THE HIGHWAY TO CHECK MY ENGINE. I COULDN'T SEE A PROBLEM BUT THE CHECK ENGINE LIGHT STAYED ON AND THE LOSS OF POWER CONTINUED. I HAD TO DRIVE MY CAR HOME SLOW. THE NEXT DAY I NOTICED THAT THE CHECK ENGINE LIGHT HAD TURNED OFF AND I WAS ABLE TO DRIVE THE CAR NORMAL. THE LOSS OF POWER IN THAT SITUATION WAS SCARY AND COULD HAVE GONE A LOT WORSE. I KNOW I AM NOT THE ONLY ONE WHO HAS EXPERIENCED THIS PROBLEM. I HAVE SEEN BLOGS AND YOUTUBE VIDEOS WHO DESCRIBE SIMILAR EXPERIENCES. PLEASE HELP FIND A SOLUTION BEFORE SOMEONE IS SERIOUSLY HURT DO TO THIS PROBLEM.

WHEN I'M DRIVING THE CAR SEEMS TO LOOSE POWER THEN IT ACCELERATES LIKE IT HIT TURBO POWER AND THE ENGINE LIGHT COMES UP. IT ONLY HAS 57000 MILES. WHEN I DRIVE IT ON ECO IT RUNS FINE AND WHEN I CHANGE TO S START GIVING PROBLEMS. THE CAR FEELS LIKE IT STALLS, ALMOST AS IF IT'S GETTING NO FUEL. MY MECHANIC ADVISE ME TO GET IN TOUCH WITH YOU AND SEE IF YOU CAN ADVISE ME ON WHAT TO DO WITH IT, BECAUSE IT SHOULDN'T BE HAPPENING. THE ACCELERATION ISSUES WITH THIS VEHICLE PRESENT AN IMMINENT THREAT TO SAFETY OF BOTH DRIVER AND OTHER VEHICLES.

I BOUGHT THE CERTIFIED CAR AT 50K AND AT 70K MILES, RIGHT AFTER THE WARRANTY ENDED - CHECK ENGINE LIGHT CAME ON AND THE DEALERSHIP SAID IT WILL COST $8K DUE TO CAMSHAFTS TO REPAIR!! THEY EVEN SUGGESTED THAT I SHOULD CONSIDER TRADING THE CAR IN! KEEP IN MIND I STILL OWE $28K SO THAT OPTION IS OUT! SINCE THEN THE CHECK ENGINE LIGHT STILL ON EVEN AFTER I GOT IT REPAIRED AT A LOCAL/AFFORDABLE MECHANIC AND IT'S ABOUT 110K MILEAGE AND THE ENGINE IS RATTLING AS IT RUNS. THIS IS MY 3RD BENZ AND THE FIRST 2 FAILED DUE TO THE TRANSMISSION FAILURE. I JUST CAN'T BELIEVE THESE GERMAN CARS CAUSE SO MANY PROBLEMS AND SO COSTLY TO REPAIR. WHAT HAPPEN TO YOU PAY FOR WHAT YOU GET!!! TODAY, WHILE I WAS DRIVING THE CAR JUST SLOWLY STOP AND THE ENGINE CUT OFF! AAA CAME TO CHECK AND IT'S NOT THE BATTERY SO WILL NEED TO GET TOWED. STILL OWE $10K LEFT- I DON'T KNOW WHAT TO DO! NO OTHER CAR TO DRIVE .

CAR SHOWED SIGNS WELL BEFORE VEHICLE STARTED SHOWING CODES. WHEN I WOULD START IT UP THE VEHICLE SOUNDED LIKE A ROCKET SHIP WAS ABOUT TO TAKE OFF AND SHORTLY AFTER THE NOISE WOULD GO AWAY. WITH NO CODES MERCEDES TRIED REPLACING THE SOME AC PARTS BUT IT DIDN'T HELP. I JUST ASSUMED THE NOISE WAS HARMLESS IF MERCEDES SAYS NOTHING'S WRONG THAN IT MUST BE OKAY. THEN ONE DAY I WENT TO TURN THE CAR ON AND IT HESITATED MAKING ALL KINDS OF NOISE BUT ALWAYS STARTED AFTER HOLDING THE KEY IN THE ON POSITION AND PUSHING FORWARD. CAR SEEMS TO WORK WELL ONCE STARTED BUT I AM USING MORE GAS WHICH MIGHT BE RELATED.THE CHECK ENGINE LIGHT CAME ON AFTERWARDS AND WOULD TURN ITSELF OFF. AFTER BRINGING IT TO MERCEDES THEY STATE I NEED A NEW INTAKE VARIABLE CAMSHAFT ADJUSTOR AND IT'S A GOOD IDEA TO REPLACE THE EXHAUST AS WELL SINCE THERE'S NO CHARGE FOR ADDITIONAL LABOR SINCE THE EXHAUST ADJUSTOR IS GOING TO BE ACCESSIBLE. MY CAR IS AT 68,000 MILES AND WELL KEPT THIS IS A MECHANICAL ISSUE WITH MERCEDES IN MULTIPLE MODELS AND YEARS.

ON MULTIPLE OCCURRENCES THE VEHICLE HAS STARTED TO MISFIRE AT RANDOM TIMES AND SPEEDS RANGING FROM 45-70 MPH RESULTING IN "LIMP MODE" OR A STALLING CONDITION. THE CHECK ENGINE LIGHT COMES ON, BUT WILL NOT BE ON WHEN THE VEHICLE IS RESTARTED. THE DEALERSHIP ON NO OCCASION HAS BEEN ABLE TO DUPLICATE MY CONCERN ALTHOUGH OTHERS HAVE BEEN IN THE CAR TO WITNESS. I FEEL VERY UNSAFE DRIVING THE VEHICLE AS WHEN IT STALLS ON THE HIGHWAY, I LOSE STEERING AND BRAKES AS WELL. *TR
