I was driving on the highway my car sort of hesitated for a brief second then continued on as if nothing about one mile later my car began to slow down while I was in traffic so asap I pulled over at this point I could only go about 40 miles per hour which was very terrifying at that time it came a complete stop. After restarting the car 3-4 times it stayed running I continue home which was about 12 miles from my current location. For the next few days I did not go any where. I then had an appointment to have the 80,000 mile maintenance I mentioned the problem I was then told I need a throttle body replacement costing more than $2000 that I can not afford. At that time I started researching my own problem. My relative who works on 18 wheel truck for a living, . that perhaps it just may need cleaning rather than replacement . …

Hola a todos. hace 3 meses compre un mercedes benz c250 a o 2012 en argentina. A eso de tener un mes el auto sal a la ruta. (Ac en argentina es muy normal que las rutas sean de un solo carril y doble mano, por lo que hacer un adelantamiento tiene que ser una maniobra muy precisa). Al querer acelerar mi auto a fondo se me cort la aceleraci n bruscamente. Perdi la potencia y me encendi la luz amarilla del check engine. Por suerte pude llegar a pasar. Legu a mi casa sorprendido e investigu en las redes. Me encuentro con que la bomba de alta presion de mi veh culo tiene una falla (aparentemente le pas a mucha gente) Espero que estas quejas lleguen a las autoridades de mercedes benz y se hagan responsables antes de que esta falla provoque un accidente mortal. ENGLISH TRANSLATION: Hello everyone. Three months ago, I bought a 2012 Mercedes-Benz C250 in Argentina. …
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
