Alarming after auto start

[Bobbijean1209]

Hi everyone,

With my 2015 Yukon xl Denali, it has been recently alarming after my remote start times out. It will even sometimes say “Theft Attempted” when I go to start it. Has anyone seen this before and know how to get it to stop? I’m sure my neighbors are starting to hate me lol!

Thank you!!

How old is the battery. Weak battery is the major cause of electrical gremlins on these newer style vehicles.

Did you figure anything out. My wife’s Denali is doing the same thing. It has a newer battery. Not sure what to start with
