Mercedes-Benz C250 won't shift problems

Filed Aug 9, 2024 · Acceleration, Engine · NC

Driving on [XXX] to Atlanta GA my car would not automatically shift and began to vibrate badly. I was almost hit by other vehicles as I pulled off the highway to check car out. Car was vibrating badly in idle and when I resumed my trip back home the car would not accelerate properly and caused tremendous stress and danger. Figured out that car would not shift automatically and I was forced to shift the car manually. Car would sputter and vibrate badly and would only slightly less vibrate to where I could drive it home in gear D5 and would less vibrate at 75+ mph very dangerous, and would lose power and shake violently going up highway hills. I prayed all the way home and barely made it shaken. I called my Mercedes Benz Dealer from the highway and immediately scheduled appointment on 8/15/24. This was a major safety hazard and life threatening situation with my Mercedes Benz C250 2014 car. My car 100% serviced over the years at dealership I bought it from Rick Hendricks Mercedes Benz of Lake Norman NC. Thank you for your time!

I bought my 2014 C250 back in 2017 with 17K miles and currently has 58,570 miles. The issue is with fast acceleration from a stop or slow moving. When trying to accelerate to merge with traffic after a few seconds the vehicle goes into limp mode and the check engine light comes on. In limp mode I am only able to accelerate very slowly and this is a major concern for my safety. This has been and ongoing issue over the past few years and I have learned to reset it temporarily (around 10 times) with a YouTube fix. I recently found out that there was a recall for the high pressure fuels pump on some C250 models but mine was never included. I also found out that the recall time limit has expired. Please investigate and expand the recall along with the time limit so my vehicle will be included.

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.

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.

My vehicle losses power and car moved into (limp mode) during the acceleration process for passing, merging onto freeway, coming out of a corner and accelerating. Upon dealer diagnosis p0002 comes up as hpfp as the cause, and I was notified as this being a common issue with the 1.8l motor in my vehicle. Along with timing chain, and tensioner. I was told these issues while driving are directly related to causes accidents.

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.

Hello, this is a flaw in the mercedes m271 engine. After a certain amount of milage the camshaft and timing chain have been malfunctioning in most mercedes c250 cars. The dealer is asking $4400 for the repair, and mercedes did a recall on it years ago the camshaft adjuster solenoid is very faulty as it happens to most c250 vehicle owners. Ever since it happened to my own car every time I start it sounds like its about to blow up. The check engine stays on every day, sometimes it'll go in limp mode and I would carefully take the car off the highway.

When accelerating, the car will just lose all power and stop accelerating. This throws you forward and kills power to the engine preventing you from speeding up. It then goes into limp mode and have to restart the car several times before exiting limp mode. When taking the car to the dealer they say it just detects a fuel error and stops the engine to prevent damage. This happened once on a highway and once on a city street as I was turning.
