In owners’ own words
Source: NHTSA complaint databaseFiled with NHTSA by the people who own these cars, about the electrical system. Quoted as written, with anything identifying removed; unverified reports — what was said, not a finding that it was true.
Since purchasing the vehicle in April of 2021, there have been significant issues with the audio system. This was noticed before the first payment was ever made. We had a “Act of God” claim made on the car for a tree falling on the windshield around this time. It was mentioned to the collision center at the time, but it was dismissed.
While driving at approximately 65 MPH all electronics shut off and turned back on moments later. This includes the gauges, radio and all lights including headlights. I took it to the dealership in which I purchased the truck from.
Truck stationary. Started engine. Immediately message showed up on dashboard indicating steering assist low, drive carefully. No power steering. Traction control warning lit. Shifted into reverse; truck would not move as if in neutral. Truck move move forward in drive but would not shift out of low gear.
This truck has so many issues first one was a fuel pump sending unit and it appears to be linked in with a lin data base? I had it repaired was good now it pops on again but its saying it can be something in the lin system sad todays cars are just filling up the junk yards and charging 50k for a new one its sadly piss poor quality
The rear defroster light is flickering. This is a known recall in canada for this same year, make and model. This is a fire hazard
