When the Auto Idle feature is on, the car will often completely turn off when at a red light or in stop & go traffic. When it is time to move again, I cannot go. Cars are honking at me to move, but the car will not start. I have to put the car in park, completely turn it off, and restart it. This sometimes happens on the interstate in heavy traffic, which can be extremely dangerous. My cars engine light had been having a warning sign emissions system problem. I took it to the dealer, and told them about the auto idle problem & the light, but they could not find anything wrong. A few months later, my engine failed & they said it wasnt covered under the recent recall so I had to pay $7,000 for a new engine. Now a few months later, the auto idle problem is happening again & the emissions system problem light is back on again. The new engine is only a few months old
