STEERING, UNKNOWN OR OTHER
I was driving on a straight away doing the speed limit which is reported seconds before the car crash. The steering wheel turned to the left really hard out of no where and wouldn’t let me gain control over the car again. I was sober it was 9am and I was aware of my driving. I ended up spinning out and landed in the ditch feet away from the light pole. I made it know to everyone what happened, but they looked at me crazy. I stopped driving that car and sent it back to Mercedes to get a detailed inspection. Which lasted about 30 days for them to get back to me about what happened. When I received the call to get my car they didn’t provide any information about the incident. Instead they just sent it to corporate and left me in the dark. I was in pain during this whole time. I was couldn’t find a lawyer that was willing to help. It’s been three years since the incident and I will have to live with pain for the rest of my life. It’s not fair that we need thousands of dollars to be heard. I have all communication and documentation that was given during the time of incident.

STRUCTURE:BODY
During a routine maintenance inspection at the Mercedes dealer, the mechanic found the rear subframe on the left and right sides of the car is rusting. Eventually it will rust through and possibly causing the loss of the control arms and wheels. At that point the car could become uncontrollable. The issue was discussed with Mercedes Benz USA Customer Advocacy. They informed me the once a vehicle falls outside warranty repairs are at the owners expense. Although the car is 8 years old it has only 51,000 miles. This is a known issue with my model year and in fact there is a recall in Canada for this issue.

SERVICE BRAKES, FUEL/PROPULSION SYSTEM, SUSPENSION
The rear drivers side had a loud chunking/clanking noise while driving and the vehicle was unable to control and break when in motion. Driving was impossible as the breaking component was a total failure and car could not be controlled while traveling down 45-50mph zone. I reduced my speed to 20-25 mph by letting off on the gas to get better control of the car if breaking would need to be suddenly made. I relied on the shoulder to pull off if any sudden breaking was needed. The car was immediately take to be reviewed by a specialized Mercedes benz mechanic and further inspection proved that the rear subframe on the driver’s (left) side was corroded and broken. The connecting arms are rusted, corroded and rendered the car inoperative. I notified my insurance company as well as car manufacturers corporate office. I researched this issue further and discovered that this reoccurring issue with this make and model. There are a pheletera of recounting of this same issue on various message boards to validate the same issues and callouts I found. The car was taken to the dealership that it was purchased and further inspection showed that the left side subframe/ subframe arms were corroded with rust and broken. The brake lines and fuel tank were equally rusted and corroded. The service manager confirmed that this is defect of the car but it had been part of a recall. I had the car towed for 2nd opinion to another dealership service department to access the car and this callout further validated the corrosion and rust was wide spread and has rendered the car inoperable unless these damages were fixed.

SUSPENSION
Rear suspension is rusted and the arm to the wheel has disconnected. This vehicle can’t be driven and is a major safety issue - per the Mercedes dealership. From Mercedes : The rear sub-frame serves a number of purposes. It adds to the rigidity of the rear body structure and supports the vehicle's cabin and some chassis components. Most importantly, the sub-frame helps to protect occupants in an offset rear impact. In a collision, the sub-frame first helps to absorb some of the impact forces on the side that is hit. It also channels some of the impact forces to the side of the vehicle not involved in the impact. This also helps to absorb some of the forces of the collision before they can reach the passenger cabin Reason A damaged sub frame puts everyone in the vehicle at risk. During a collision the sub-frame is responsible for absorbing and evenly distributing the force from the impact. If damaged the sub frame cannot distribute the impact causing a complete collapse of the vehicle.

ENGINE
The engine stalled at idle numerous times when at a stop light or stop sign. This was dangerous as the other cars could have ran into my car in anticipation that I should be moving with traffic. The car was taken to the Mercedes Marin dealer service center and diagnostic was done indicating a cracked piston in cylinder one was causing loss of compression and could also cause engine failure at speed if not taken care of. Check engine light DID NOT come on. During research on repairs for this issue, it became apparent that Mercedes Benz is aware of this issue in many of its engines of this model and year, but did nothing to remedy the situation or the underlying manufacturing defect that causes the cracked piston. In addition, Mercedes is unwilling to cover the cost of repair or replacement (car has only. 49,000 miles, but is out of warranty due to age).
