When I saw the traffic begin to inch forward I tried to turn the car back on, but it wouldn't budge. I didn't even hear the starter turn. …”
NHTSA complaint #10275107, filed 2009-06, 107,000 miles“I have manual transmission. When you put it in reverse it would not go backward.

They kept telling me to drive the car and it would work, it way out. It did not work its way out, and I took it back in for repairs. They had the car 9 days. After I picked the car up, a few days later I realized the reverse lights were not working, I took it back to the dealer and they said it was a fuse . …”
