2019 Silverado LTZ... Found this forum today. 3900 miles - and owned 13 weeks. Six trips to the dealer for a variety of issues including brake system failure, leaking back window, cameras non functioning, lane assist failure... I saw someone state their truck is FUBAR which I haven't heard in years - but a perfect description. Most recently brake system failure do not exceed 62 mph... dealer had it three days and the repair order says "couldn't duplicate the error code" - translated means "the owner is crazy".. well after reading this forum - I can see there is someone crazy and it ain't ole Tim-o!. FYI - I have never used the app for remote start - only the key fob occasionally. I'll let you know if any further codes arise... thanks for helping me understand that this problem is more common than I imagined.
