So as the title reads the dealership is claiming that my awesome audio system is the cause of a TPMS issue.

It all started around the 25th of April. Saw the service tire pressure monitoring system turn on my car and the driver rear side tire showed blank. So did the relearn, went away but would come back the same day so I booked an appt at my dealer. Friday 4/27 the dealer goes ahead and replaces the Left Rear and the Left Front tpms sensor. Same night issue comes up again with the LR tire. Next morning I did a relearn and it goes away but came back that same day. So 5/2 I'm back at dealer and the service guy immediately says it's my radio causing RF interference. So I call Kenwood on the spot and guess what? the radio doesn't output any RF signals. So he goes back and talks to the service manager and now his claim it's the GPS signal of my Navigation. To test out if that's the problem he wants me to disconnect my radio completely and let him keep it in the shop to monitor if it comes back on for about 2 weeks. Says the GM engineers are going to make him unplug the system so it has to be done. Problem is this thing doesn't turn on when I first turn on my car as it just randomly turns on afterwards. It's been anywhere from driving 5 minutes to 50 minutes at various driving speeds.

My installer has no issues unplugging it to show them it's not the issue so big ups to my installer again for not charging a dime. I don't have time this month to get this done as I have some trips planned so goal is to bring it in next month. So I'm building this thread because I didn't find anyone with my circumstance so hopefully it can help someone in the future.

Here is my audio install history
· Had my subs installed last year using the ******** harness and I also put sound deadening on the entire trunk.
· Upgraded my front speakers, sound deadened the door and all rear panels. Installed Scosche with Kenwood 9980 on 2/20
· Receive my new Kenwood 9990 and had it installed 4/14. Installer also attempted to update the dash kits firmware
· TPMS issue started 4/15
· Installer tries to troubleshoot issue. Mentions his dad (a service teach for another gm dealership) recommended the replacement of the dash kit and nav to the factory stario since he doesnt fell removing the nav will do any good for troubleshooting. Installer also attempts to update firmware again since apparently what he thought was successful 4/15 was not the case. Firmware says succesfully update but kit dies. Warranty exchange submitted and sent product back to scosche for new dash kit 5/23
· Drove all day 5/23 and no issues with TPMS. Dash kit seems like probable issue.
