 This truck bucks, jerks and intermittently locks up the rear differential with a bang that stops or slides the rear sideways. After 6 morning months of the truck sitting in my driveway or at the dealer waiting for s factory rep to drive, his only words were operational as expected????   I had to eat 14,000 dollars to move into a 4 Runner I really didn’t want, or lose more because it was a (Used Truck).  Alaska has no dealer support and corporate are hiding behind the brand.  This truck is going to injure people and then maybe toyota will fess up.  I am having a few issues with the 4 Runner but have to drive to Seattle to get warranty work???  Not happy . I have been a mechanic for 37 years and would not drive this unsafe truck.
