From my research there many people one gm forums that have brought their truck into the dealership (for months) for this issue, they changed the battery, starter, underhood fuse panel, the fuel pump module, the steering column module, ignition switch, harnesses and they still don't have it fixed.that video above is another perfect example of a the dealer doing the parts cannon to troubleshoot.  The result is the customer is frustrated about wasting there time/ not having a truck, the dealer  and engineering are scratching their heads on an issue that is labour intensive to figure it. Thats why I will never bring my truck to the dealer. If you ask chatgpt which is the most unreliable truck for every year from 2019 to 2024, the answer for every year is the gmc/chev 1500. Ford doesn't use corrosion prone ground straps. For those years the f150 was at the top of the reliability rankings. So what is the solution to all these problems? Having a truck that didnt want to start start 50 times in 4 years with 85k km  of ownership has left me severely regretting choosing a brand that I thought was reliable at the time of buying it.
