   While driving at normal and safe highway speeds, without warning (no audible or visual warning from the vehicle information display) my vehicle experienced engine lockout, loss of all non-electric power, and no control over vehicle speed. A few seconds after loss, the information display did show a "check engine light" and that the engine was in "lockout."

   I purchased the truck at the end of March 2025. Within a few weeks I was noticing different issues in the transmission. It would occasionally shudder, have jerky or long shifts, would jump gears and lose power. The shudder was random but mostly on the highway, the jerky or long shifts would mostly occur when the egjne was cold and more often in cold weather. The lose of power and jumping gears would occur when towing and when I was in the mountains, once losing power as I…

   Engine fails it violenty thumps and studders and drops from highway speed with no warning. This is a mfg. defect and also an EXTREME SAFETY CONCERN.

Dealership confirmed that they have many vehicles with same issue and recommended a Super Flush of transmission but not sure this will correct problem or cause more problems. There is no…

   Luggage and shudders at cruise speed, seems like auto transmission is coming apart. Paid $500 for the trans flush the service bulletin suggests but didn’t help, shop quoted a $8000 replacement on a vehicle with 60k miles. This should be a recall

   Clunking sound coming from rear end upon normal acceleration. When I take my foot off of the brake pedal, and depress the gas pedal, A loud clunk appears to come from the differential. If I coast first and then depress the gas pedal, it is not as pronounced. When you slow down to make a corner, and resume speed exiting the corner it is also pronounced. It should be noted that I am a safe adult driver (safe driver module installed in truck) and have 35,800 miles. My truck has…

    At around the 105k mile range the truck would make a gear whine sound and shudder between gears at around the 50mph range, speeding up or slowing down a bit would fix the issue. By 110k miles the truck was making the gear whine sound at speeds over 10 miles an hour studdering at every gear change. I took it to a mechanic who said there were no TSB's for the truck and suggested doing a trans oil dump and filter replacement. The trans filter was replaced, and 7 quarts Mobil1…
