Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“Traveling on I-5 in stop and go traffic 0- 60 MPH when transmission started shifting roughly. It then shifted to neutral and would not respond to shifter inputs. I was in the second lane from the right doing 10 or 15 MPH. I was able to force my way into the right lane and off to the shoulder. I put the transmission in sport and paddle shifter mode with no response from the shift selector. Thinking this is a computer problem I rebooted by shutting car off and restarting. All functions returned to normal. …”

NHTSA complaint #11021314, filed 2017-09, 28,000 miles

“The contact owns a 2013 mercedes benz SL550. The contact stated that while driving approximately 40 MPH, the paddle shifters were operated and the connector plate failed without warning. The contact mentioned that the vehicle failed to accelerate. On another occasion the contact stated that while coming to a complete stop, the vehicle lurched forward without warning. The vehicle was taken to a dealer where the failure was unable to be replicated. The manufacturer was notified of the failure. …”

NHTSA complaint #10558190, filed 2014-01, 1,200 miles

“Started the vehicle and used the gear selector to shift to Drive. Car did not go into gear. Towed to dealer. Dealer found faulty “ism module.” Apparently a very common issue with these cars. So common that the part is in an “indefinite back order.” The replacement part is also revised because Mercedes knows there was a manufacturer defect with the existing part. I am being charged more than $1600 on a part that the manufacturer has already acknowledged was faulty and created a replacement for it.”
