car was at the dealer for a month getting rear end damage repaired. exhaust system was replaced too since it was bent after getting hit. just get car back and im not sure if its just my imagination or not but i feel like there is a stutter when the car starts up that wasnt there before.

 

Maybe you need a new battery? The lights are flickering when starting up and I notice that on my IS only when the battery was weak or needs replacing.

 

Yeah you need new battery.
