“I took the vehicle to the dealer for recall Manufacturer Recall Number13A NHTSA Recall Number23V-060 The dealer told me that they can only order one per week. I will have to wait over a year for the part to come in. This is a fire hazard and I have been advised to not park the vehicle in the garage or near other vehicles. Waiting over a year for a fire hazard repair is not acceptable.”
NHTSA complaint #11533101, filed 2023-07“The Auto lights sensor turns lights on/off at random during dark/night driving. The high beam auto sensor keeps the high beams on, so you do not notice losing driving lights. I found this out by accident, when I started losing my trailer lights at night. Quick fix, turn the light switch to on, instead of auto. NOTE - Cost me over 1000.00 to find that out. Re-wire the trailer, replace the 7-way plug.”
NHTSA complaint #11482571, filed 2022-09“While driving my truck I noticed my mpg gauge was showing 0 mpg. Then I realized my miles to go gauge was reading low even though I had plenty of fuel in the tank and my fuel gauge was showing 3/4 full. Even though I use my truck as a commercial vehicle, and drive coast to coast, I was luckily only a couple hours from home, so I kept driving to try to make it home. I did make it home, but during that time, my check engine light came on along with my low fuel warning light. I also realized during that time that my odometer had stopped working. It wasn't showing any numbers at all. …”
