Has anybody ever heard of or has their engine hours zero out on their truck? I have a 2020 GMC Sierra 2500HD AT4 w/ 6.6L Duramax. This happened to me a couple months back. I remote started my truck and it sounded like it hard cranked. When I got in the my truck I noticed the engine hours were at 0, my fuel economy reset, and my instruments switched over to metric units. No big deal on the fuel economy and I just switched the units back to US but, I was more concerned with the engine hours zeroing out. Please let me know if this has happened and if a solution is possible. The dealer has never heard of this happening. Thanks, Jake
