We dropped off our vehicle and told the service tech we needed it by 4:30, he said someone would call but they never did. We called multiple times and left messages but no one ever returned our phone calls. I finally left a message at the service desk and someone did call me back but it wasn't the service technician and she couldn't answer any of my technical questions about the vehicle. The whole experience was extremely disappointing. My car ended up being there three days and they charged me over $300 for the diagnosis of a strange rattling sound that they said was normal for a car my age, 2015.
