We had a sensor go bad (who knows what kind?) while we were on the road. The check engine light came on and the transmission kept disengaging into neutral. They took our GMC pickup right in and gave us a loaner vehicle so we could finish our shopping. After about an hour, the service department called and said our pickup was repaired. When we picked up our pickup they stated that there was no charge for the loaner vehicle because we only had it for about an hour during our shopping. "That's great customer service!"
