I think I might switch. I got my car at oliviero and they serviced it once (oil change, tire rotation, and control and) and that's when this all started. I think took it to Cochran buick in Robinson and they found nothing. I live in the city so I can really get to any dealer quickly. I will look into taking it to a Cadillac dealer, thanks for the tip.I have a family member that works at a smaller Chevy dealer look at my car. I went to Wright Buick in Wexford one time and that was the last time due to abysmal service. I would probably go to one of the Cadillac dealers if I didn't have my family member. Cadillac customers are a lot less tolerant of issues so the techs are used to finding odd issues.
