I was driving my vehicle when the transmission started shifting erratically. The shifts were not smooth but hard and the car was shuddering. Yes the vehicle is available for inspection. My safety and the safety of others were at risk due to the erratic behavior of the vehicle and how it affected my ability to focus on driving safely. Yes my vehicle has been inspected by the manufacturer and the problem has been reproduced by my local Mercedes Benz dealer. There were no warning lamps or messages prior to the failure. After a few weeks of dri…

Owner report 11056561 · 2017-12-26 (December 26, 2017)
STEERING WHEEL SPRING GROUNDING PROBLEM CAN ACCIDENTALLY DEPLOY AIRBAG. RECALLED IN OCT 2017 BUT I'M TOLD PARTS WILL NOT BE AVAILABLE UNTIL MAY 2018. THIS IS AN UNREASONABLY LONG TIME. I WENT TO TRADE-IN THIS CAR TO PURCHASE A NEW ONE AND WAS TOLD THAT NO DEALER CAN SELL A CAR WITH A PENDING SAFETY RECALL EXCEPT "AS IS" THROUGH AN AUTO AUCTION, WHICH LOWERS THE VALUE OF MY CAR BY OVER $2,000 VERSUS A NORMAL DEALER TRADE. HOW DO I RECOVER THIS LOSS WITHOUT SUING MERCEDES? ARE THERE ANY GOVERNMENT REMEDIES OTHER THAN PRIVATE LAWSUIT?
