“For about 6 months I have been having problems with stalling after slowing and then accelerating. The first 3 times were not as frightening as the one that occurred on 7-7-2014.returning from a trip to new orleans,as I exited the interstate and began to ramp off, the car stalled to the point of no control of the steering. It lurched to regain speed and finally recovered. We took it to the dealer on 7-10-2014 and they did diagnostic check and found no obvious problem which is difficult to do when the problem is intermittent. I am afraid of driving the vehicle until it is repaired. …”
