“4 times in less than 4000 miles my 2026 trucks abs, cruise control, skid control, and check engine warnin07g lights have come on. I then have no anti-lock system, no cruise control, no 4-wheel drive, and no anti-skid system. Code reads-U1412. The dealer has replaced the rear speed sensors and it continues to happen. My truck is currently at the dealer in the service bay as I can't drive it. I've researched this and it's happened to many who have purchased this truck.”

NHTSA complaint #11717860, filed 2026-02

“ONLY 1,800 MI. I continue to experience ongoing issues with this truck, despite having just received it back from the dealership two weeks ago following repairs related to a rear pinon gear. the truck is now back in the service department for concerns involving the front differential. Given the repeated drivetrain issues, I am increasingly concerned about the safety and reliability of this vehicle, particularly the possibility of a catastrophic mechanical failure while traveling at highway speeds that could result in loss of control. …”

NHTSA complaint #11773114, filed 2026-10

“Trucks DEF Gauge malfunctioning goes from full, to half, to full, to empty, and then warns about going into limp mode. Filled with DEF and still doing it. Took in for repairs, company said they fixed it, but within 3 miles gauge was doing the same thing. This is a hazard as it will put the truck in limp mode. Known issue with many complaints, needs fixed”

“Trucks Navigation and GPS stopped working. Took to dealer for repairs, could not replicate the issue. They brought the truck back to me, and upon starting it the GPS/Navigation is not working. Other than the navigation, more systems work off the gps and needs to be functioning. Have multiple videos of nav not working, and dealer still stated that wasn't enough to determine there was an issue.”
