Coming off the hwy my vehicle slowed down from 55 mph to about 40 mph fairly fast thankfully no one was behind me. Check engine light came on, tried pressing on the pedals but vehicle was not speeding up at all. The traction light also came up. Took it to Chevy dealer right away and they said it was the accelerator sensor not communicating with the system. Took about a week to get my car back from the dealership.

Vehicle in motion in left hand lane, on 5 lane main road during rush hour, traffic going approx. 35 mph. As I was driving the vehicle stalled, engine light came on and a warning message said the vehicle was "slowing down" (it stalled completely). I was unable to drift into the right lane and forced to abandon my car into the center lane - used for merging from other lanes of traffic. Police responded but no report was filed. Officer suggested I leave the vehicle for my own safety & when tow truck arrived to request the auto be towed to a safe spot for removal of personal items. This situation was not only dangerous to myself but others. A crash could have been the result. According to dealer, no recall on this issue. Did have a transmission problem. Less than 10,000 miles on car approx 18 mos old. Dealer hopes GM fix will work, but I am now nervous about driving the vehicle.
