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.

Power loss when accelerating. I pulled out in traffic and accelerated but...I loss power and almost got run over from the oncoming traffic!!! Major safety issue. Engine light comes on! This is a horrible issue for anyone that has experienced this problem. I'm hoping there hasn't been any fatalities do to this problem.
