“Driving down the road at a slow speed and the car just quits. Sometimes it will start itself back up and sometimes I have to pull off to the side of the road to turn ignition off and then on again. The car will just quit at highway speeds and after some quick thinking and realizing what just happened the only thing to do is drift to the berm of the road with no pwr steering or brakes. There are also times when I start the car it will quit and takes two to three more tries. Also had a severe raw gas coming from the car after a fill up. …”
NHTSA complaint #10585061, filed 2014-04, 66,400 miles“As I was watching the gmc electronic ignition switch recall on the news this morning, it struck a chord, as the same thing happened on the above mentioned car last summer.

This was not a recall, but I thought at the time, it should be. …”
NHTSA complaint #10567540, filed 2014-03, 35,000 miles“My clk 350 cabriolet stated driving different. At first, whenever I would slow down at a stop light, the car would cut off. Everything would illuminate on the dash and I would have to turn it off and back on to drive it again. The biggest issue is that when I would drive, the car would not shift our of gears properly, and it would very painfully and slowly accelerate its speed. It would jerk, like the transmission was not functioning correctly. Come to find out, at 62,000 miles, my car needed a new transmission, with no logical explanation given from any benz dealer. …”
