Fuel/propulsion System
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.

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.

What component or system failed or malfunctioned, and is it available for inspection upon request? As I started my car from a cold start and even when starting the engine, the car was creating this tractor like sound. No system has failed but I read the camshaft adjuster and tensioner pulley has come out of site, which can ruin the engine. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes, it was audible by the dealer but I was told that it would be a normal issue on a cold start. Now they will charge $200 for a service diagnosis. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Mercedes Benz gave an extended warranty on the program for extension of 10 years but the problem has been happening for multiple people and it has been happening again that this warrants a recall over a poorly designed part that can destroy the car’s engine. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No such codes or messages. Which is why this is so scary. This incident has been happening for the past 8 months or so and besides a letter about a warranty no such information.

on 6/20/23 I was driving this vehicle on the 5 freeway north bound exit 102 in Washington. i found myself travelling at 60mph just moving over to the middle lane of traffic. i needed to slow the vehicle a little and pushing down on brakes I found there was no reaction from the braking system. Making a quick decision I moved over to the emergency lane where I came to a stop. There were no warning signs of the issue. I had the vehicle towed to my Mercedes Benz dealership where I had the car service the day before on 6/19/23 where nothing was noted on this problem. After inspection from the technician at the dealership it was found that the brake vacuum pump was no longer working. Which technician said had caused the issue and he had never experienced this issue before. i am bringing this to your attention due to it could have caused a fatal accident to with me and other people on the freeway.
