The truck would not start after sitting for a day or two. Fob would not open the doors or when using the key and pressing the push start, nothing happens. I took it to the dealer after the second time this happened and they replaced the battery. A week later, the same thing happens. This time I jumped the truck and drove it directly to the dealer, and they are stumped... I will update this when there is a fix.
