    About 2-3 months ago I had a battery swell up and start smoking and making an awful smell in my truck. I took it to dealership and was informed that I needed a new battery and it was not covered under bumper to bumper warranty or my extended warranty which I thought was ludicrous. The truck is 18 months old. It does have 50,000 miles but I have yet to see one that isn’t at least prorated for five years. So fast forward to today and the other battery starts doing the same…

    During a drive home, while in motion, the tailgate of the vehicle opened on its own. This has occurred after the recall to repair this issue was already performed. I know the tailgate was shut prior to the drive because I back into my parking spot and walk the sidewalk behind my truck prior to starting the vehicle.
