The service experience was very good.
The service experience was very good. I brought my vehicle in for an oil change and a recall. It went well but then a few minor things happened with the electronics. They were quickly fixed except I couldn’t then get the AM stations back on the radio. So the Service Dept ordered a new radio for me, which should fix this issue.
