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.

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

I was trying to merge onto a freeway from a complete stop and because this freeway has an extremely short on-ramp, you need to get up to a high speed in very little time. As such, I put my car in Sport driving mode and accelerated very hard from a complete stop. The car accelerated as normal for a few seconds (I reached approximately 40 to 50 MPH), then I felt the car lag and felt a loss of power. The car was in limp mode and I couldn’t accelerate even though I was pressing the gas pedal all the way to the floor. A few seconds after this occurred, I notice that the check engine light turned on. I was able to maintain a speed around 50 MPH and got off the freeway. I took my car to both the Mercedes dealership and an independent mechanic and both diagnosed a failure of the high pressure fuel pump. I also tried to see if this will happen again and after hard acceleration in regular driving mode, the exact same issues occurred. I have read that there are issues with the high pressure fuel pump with my car model and I ask that you guys please investigate thoroughly to see if a recall would be necessary. Losing power while accelerating is extremely dangerous and a huge safety hazard for all drivers on the road. I could have easily been rear ended by another driver since I couldn’t accelerate to a faster speed. I have not yet replaced the high pressure fuel pump but plan to do so in the next few days. Attached is the diagnostic invoice from the Mercedes dealership. As stated on the invoice, please note that my car only has 43,000 miles, which makes the high pressure fuel pump failure very surprising.

I was driving on the freeway i10 I was doing 65 MPH I try to pass a car so I accelerated the car but the car was not getting the power and my check engine light came on so I safely pull out of the freeway and inspected the car with a scanner and it showed a code so I search in google and it appears a failure of the high pressure fuel pump, I managed to take the car to my house disconnected the battery and the check engine light disappeared but the RPM's where irregular and the acceleration was failing more often. It appears that I'm not the only one that have had this problem while I was looking in google and youtube many people had the same problem while trying to accelerate.
