MERCEDES-BENZ Complaints

Getting P06DA trouble code meaning that there is something wrong with the oil pressure solenoid in the oil sump. this is a known issue where the wiring of the solenoid get frayed. cost of repair for the (cheap part) is $7,500 because of 18 hour labor involved. MB knows this is an issue with the wiring in the solenoid. I'm not sure if there is a fire risk because of the frayed wires.

I am filing a safety complaint regarding my 2023 Mercedes-Benz AMG C43 4MATIC. The vehicle has approximately 23,000 miles. On multiple occasions, the vehicle has abruptly and violently applied the brakes and/or come to a near stop while I was driving on highways and side roads, even though there was nothing in front of me that should have triggered emergency braking. There was no vehicle, pedestrian, cyclist, object, or road hazard present that would justify this braking event. This is not normal braking behavior. The car essentially performs an uncommanded emergency stop or severe deceleration without warning. The force is strong enough to create a serious risk of being rear-ended by vehicles behind me. This has happened at highway speeds and on local roads, making the vehicle unsafe to operate. If a following driver is unable to react in time, this defect could easily cause a crash, injury, or death. The problem appears related to the vehicle’s automatic emergency braking / Active Brake Assist / forward collision avoidance system and possibly other linked driver-assistance systems. The vehicle has already been serviced on two separate occasions for this exact issue, yet the problem has occurred again. Despite bringing the vehicle in for repair more than once, the defect remains unresolved. Because this dangerous unintended braking continues to happen, I cannot continue to drive the car safely with this issue unresolved. On April 1, 2025, I took the vehicle to Aristocrat Motors in Merriam, Kansas for the car slamming on the brakes and beeping when no one was around. The service center calibrated the augmented reality camera and performed a test drive. The invoice indicates that they were unable to duplicate the braking event during the test drive. They ran codes with SDS and found that the augmented reality camera was not calibrated correctly, so they performed a calibration. On December 31, 2025, I again took the vehicle to Aristocrat Motors in Merriam, Kansa

The failed component is a fuel pump, and it is available for inspection upon request. My safety and the safety of others was put at risk due to the following: 1) Sudden engine stalling 2) Dangerous power loss while accelerating 3) Potential fire risks; a damaged fuel pump assembley can cause fuel leaks and overheating due to insufficient fuel supply can increase the risk of explosion or fire. 4) Gas fumes from a fuel leak are highly harmful and dangerous. They are toxic to inhale causing dizziness, headaches, nausea or respitory issues.

While passing a vehicle on a two lane road, my vehicle lost power and went into limp mode nearly causing a head on accident. The check engine light came on and i immediately went to O'Reilly's Auto parts store and had their OBD scanner read the code. AP0002 code was read. I immediately returned home and the check engine light automatically cleared. I scanned the OBD again and found code P0002 and a second code P000277 that was listed as stored and current Both codes refer to an issue with the high pressure fuel pump. I just recently purchased this vehicle with 35170 miles. I had the OBD scanned prior to purchase, there were no codes at that time so we purchased the vehicle. We've since put 1000 miles on the vehicle and without any warning, this issue suddenly happened. I have done some research and Mercedes offered an extended 120000 mile/10 year warranty that addressed this exact issue, however, that warranty is now up due to the age of the vehicle. This issue put us and others at server risk of a major accident do to this issue happening with no warning. I haven't tried to reproduce the scenario that occurred, however the codes remain on the OBD computer.
