I had an engine light on for 4 secs. Contaced onStar and they let me know i had misfires. I then contacted the closest dealership, Superior Chevrolet in Lawrenceville, NJ on Route 1. They told me to bring it in the next day at 2:30. So I did. I get there, talk to the lady at the desk and she says, "Well, I don't have anyone here available for warranty repairs, only oil changes." I was kind of disappointed, but I can see how a message wasn't relayed. then she tells me to bring it in tomorrow so they can check it out. I had a problem with this since it's my only way from point a to b. I wasn't going to take off of work. So I ask her about Saturday, and she said "Oh, well, we don't have anybody here who can do those kinds of repairs or work on weekends, just oil changes." As this fun conversation is going on, two techs are just sitting around staring at the ceiling. I lied and said I'd bring it in the next day. Instead, I went to Reedman Chevrolet in Langhorne and told them what's wrong with the car according to OnStar. Less than an hour later, they let me know everything is fine it just had 30 misfires and to just keep an eye on it. If this seems like a ramble complaint, sorry, but I just can't see how a much busier service center was able to help me in no time with no previous knowledge, while an empty service center was dumbfounded on how to just check out why an engine light was on for a blip of a moment.
