Check engine light comes on and the engine has stopped while in motion, have had it checked out 4 times already. 1st time dealer said there were some wires that are close to the manifold were frayed and then repaired. The last 3 times the check engine light came on I pulled over while driving, turned the engine off waited a few minutes and restarted the car and was able to drive a few miles. I have now taken the car to a different for dealer 3 times in the past 5 weeks and every time it's a different code with the exception of the 3rd time. They replaced the battery at no charge now today 5 days later the check engine light came on again. This will be the 5th time! this has happened on the highway and on city streets. We have spent over $500 and my time getting back and forth from this dealership to remedy this problem.
