2011 GMC Denali - Check Engine Light and Remote Start

Customer brought his 2011 GMC Denali in because of a check engine light and remote start had stopped working. The code we pulled diagnosed the issues as a catalytic converter problem. We didn't think the car needed a new catalytic convertor.

We noticed a very loud exhaust leak coming from the front catalytic converter connected at the Y-pipe. We disconnected the Y-pipe from the catalytic converter and noticed the gasket had disintegrated. We ordered a new gasket from GM and replaced it. We reprogrammed the computer and all was well. The remote start was a blown fuse. Now the owner can start the car from inside his house and let his car warm up before he goes to work. Good thing - cause it's freezing out.
