   In May 2025 the vehicle randomly, and without warning, the instruments, gauges, and displays switched to Italian, changed to Metric, and we got the update and FCW Off light stuck on. Numerous other settings had been reset. Took to dealer and had to pay for the fix - they noted a STAR bulletin on my invoice. Then this past weekend (May 2, 2026) it happened again. At least this time it didn't go Italian and Metric on me, but lots of other settings were changed. Did not test…

   At 78,800 my truck started experiencing "stuttering" trying to pick up speed like the transmission wouldn't shift into gear and the Uconnect stopped working simultaneously. Also seems to be burning through more oil. It happens every single time you take off from a stop until the vehicle finally shifts into gear, it's very scary and very dangerous when you're trying to merge onto a beltway and you can't pick up speed correctly.

    Started driving home and heard the vehicle making clinking noises. Then the service 4wd light came on. It slips in shifting almost like the vehicle shuts down for a sec and then comes back. When you are sitting the vehicle will randomly jerk forward even in park mode. Like the brake releases and then comes back. It's very unsafe and with it shifting the way it does the actuator is failing which in return will cause a very bad accident. This car can just shut down at any…
