-The steering wheel and brake locked up and became unusable while driving at approximately 75mph. Cruise control was enabled for a few miles (maybe 2) and disabled after. Around 5 minutes after disabling, the car began to surge between acceleration and deceleration drastically on its own. All of the dashboard lights that come on when the key is initially inserted came on at once while engine was on/running and the car was in drive. After finally being able to reach a safe enough spot, I put the car in park and turned the engine off. I sat for a few minutes to try and turn the engine/car back on and the car would not crank, but the overhead lights, radio, and dash lights were functioning. -This was an extremely dangerous experience. The car began to decelerate rapidly in heavy freeway traffic. At that speed, with many semi-trucks traveling nearby, this sudden loss of speed created an extremely dangerous situation. My vehicle instantly became a slow moving obstacle in the lane. Only by luck and quick reaction was a serious or fatal collision avoided. The car would not start back up so I was sitting at the edge of the highway as many cars flew by just inches away from my car. -I am away at college in a rural city. Accessibility is limited as well as support because of lack of resources. -The car was towed to a mechanic who does not specialize in German cars and stated they did not have the proper tools to "get into the car" because the motor is "locked up" and the car wouldn't c

The model/year Mercedes-Benz are well known for experiencing this/these particular issues. My research has shown that these year/make/model vehicles are experiencing the same type of mechanical failures nationwide. The issues all relatively begin around 75,000 miles. I've only had my car 3 years putting 30000 on it hardly driven/cared for **Issue Found:** Oil was leaking onto the ignition coil and spark plug of cylinder 3. **Source of Leak:** Valve cover gasket failure. **Recommended Repairs:** - Replace the valve cover gasket (to halt the oil leak). - Replace spark plugs and ignition coil (which were contaminated/damaged by oil). **Relevance to Warranty:** The valve cover gasket is only covered if it fails as a result of an internally lubricated engine part causing damage. Ignition coils and spark plugs are maintenance items and are not covered by warranty plans. **Required Repairs (Identified Mechanical Issues)** - **Coolant Pipe Leak – $850** **Issue:** Coolant leaking from a pipe on the side of the cylinder head. **Relevance to Warranty:** Typically not covered unless it pertains to a failure in a covered system such as the water pump or cylinder head due to an internal breakdown. This is likely classified as an external plumbing component, which is not included. - **Oil Feed Line Leak – $600** **Issue:** Oil leaking from the side of the engine, traced back to the oil feed line. **Relevance to Warranty:** This is not typically covered unless the oil feed line is part of t

1. The car radio, blue-tooth, speakers, sound, car remote sound. Happened after a battery change by AAA - unsure if it's related. CUstomer service tried to resolve it - radio turns on, but nothing else works. 2. Doors won't unlock outside or inside - except passenegers side is open. 3. Accelerator acting strange - won't pick speed after 30, then 60 4. there was an air bag recal of this car a while ago.

Lost of drive power and the vehicle steering wheel locked on my mercedes from a damaged malfunctioning steering lock actuator module due to mechanical issues within the steering column such as bad steering wheel assembly, faulty steering lock module or issue with the wiring or other electrical components and the mercedes dealer is the only one who solves this issue no other mechanic in general.

Weeks later I got an email asking for more money they wanted another payment for $600 saying it needed a sensor that has something to do with the transmission because after replacing the new module the vehicle did not start up there was no type of communications nothing at all and I responded that I was not going to pay $600 more just cause they don't know what their doing because they promise me the car was going to work after they replace the module now that it did not want to crank up they found anoth

I got stranded in the middle of the street my vehicle does not crank steering lock so I had my vehicle towed into the Mercedes dealership the one in Figueroa st Monday November 18 2024 at around 03:24pm and this is what they told me. Needs immediate attention custom recommendation ELECTRIC STEERING LOCK During vehicle inspection found electric steering lock has malfunction code 25464 recommend to replace electric steering lock first and perform re-check.

Active headrest on front passenger seat forcefully deployed without any collision or impact occurring. It happened during a gradual stop at red light. Bits of broken plastic were found on the passenger seat after deployment. Cannot re-set the headrest because of broken parts. No one was in the seat at the time but now concerned that the same thing will happen to driver's headrest.

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.

1) cranshaft and camshaft position sensors, timing problems and it has to be replaced this is a common damage in Mercedes Benz 2012 c250. 2) this put in risk my life because it can brake the engine in a highway and the car could be off.

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.

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.
