Hello and Welcome to JustAnswer. I am reviewing your question and will be back with you in just a second.
If the check engine, trac, and vsc lights are on there will be some trouble codes stored in the ecm. It is possible that there is a loose connection or connectors during the repair. What kind of repairs did they perform at the dealer?
I put it in the shop for the same problem. the check vsc, rocking and etc. They had worked on it for two weeks thats why I was surprised when the light came on the very next day that I got it back. The only thing I can think of is the day before I filled up the tam
tank with premium and my dad says that I still could had received bad gas
The first place to start is to have it checked for codes. Most autopart stores will check it for free(like Autozone). If you can get me the codes I can look them over for you. Doing that will help with the diagnostic process and give you some ammunition when you take it back to the dealer. When they check it tell them not to clear the codes, just check it.
its back in the dealership already. I was just wondering if this was something that someone might have encountered before and had any thoughts on the cause. I googled it and a few people wit the same exact problem said that it was bad gas and someone else said they had to get the fifth coil replaced.
Ignition coils are a common problem on that model. If they had the valve covers off replacing gaskets it may have some VVt problems. It is hard to say exactly with out knowing what codes are stored. The check enging light can come on for many diffrent reasons. Most times with bad gas it will cause a misfire and the check engine light will flash.
