This Problem Across All Years
On the afternoon of February 6, 2024, as I was turning into my driveway to park in front of the garage, my car unexpectedly accelerated despite my foot being on the brake pedal. Despite my attempts to brake, the pedal didn't respond, causing the car to collide with the garage door and subsequently damage storage shelves and containers inside. My mother and two brothers were passengers, returning from my mother's doctor appointment, and she became trapped inside due to the garage door collapsing onto the car. Emergency services were called, and both the fire department and police assisted in freeing my mother from the vehicle. However, the police did not file an accident report since it occurred on private property. Subsequently, I contacted my insurance agent, and the car was towed to a repair shop recommended by the dealer. Today, I was informed by the repair shop that the damages are extensive enough for the car to be considered totaled by the insurance company. Fortunately, the incident did not occur while driving on the freeway or public roads earlier that day, potentially averting a more serious accident. Nevertheless, the ordeal has caused considerable stress and sleep loss for all involved. I have since reached out to the repair shop and dealer to conduct a thorough diagnostic analysis to determine the cause of the malfunction. I've requested copies of the data captured by the On-Board Diagnostics (OBD) system and Event Data Recorder (EDR), emphasizing that this data should not be deleted without my consent. However, I am uncertain about the next steps if the insurance company removes the car from the repair shop and how to access the requested data. Upon researching online, I've discovered numerous similar cases involving Mercedes-Benz cars, with over 20 incidents reported and 11 specifically concerning the same model as mine.

On Tuesday, the steering wheel failed to operate while making a left turn. While making a left turn the steering wheel locked and the brakes did not function to stop the vehicle. The vehicle continued to steer to the left and I almost hit another vehicle head on. What stopped my vehicle was the emergency brake system activated by almost hitting the other vehicle head on. They luckily saw me head on and tried to quickly move out the way. This happened two times the second time Thursday, there was a school bus to the left of me my car. I was not making a left turn but on a road that the curve went left and the steering wheel locked in that position. My wheel was locked and failed to stop for about 45 seconds with no car in front to trigger the emergency brakes. Immediately to my left was a school bus. The school Bus was not expecting my vehicle to cut them off in this manor, the bus had to make a hard stop to not crash into me. I feel my life and the life of the individuals in the other vehicle and school bus were all put at risk. I towed my car to the dealer and was advised that they did not see any recalls for my vehicle. They also advised me that based on the inspection and the incident details that they would need to replace the steering rack and pinion. My vehicle was operating as it normally did and did not have any system warning prior.
