Example complaints

Electrical system: “I have been stranded numerous times with this vehicle. Some battery gremlin or electrical gremlin. Brought to the shop and they said there was a recall that was fixed. I went to the store 2 days later , came out with $400 worth of groceries and go to start my truck and nothing . Blinking flashing electric glitching . It took 15 minutes of just trying to jump it off!!! Annoying and dangerous !! Obviously the recall is not fixing the issue with this truck .”

NHTSA complaint #11320766, filed 2020-04, 34,000 miles

Other or unknown: “I was driving down the road, only vehicle on the highway and it was a clear, hot, and sunny day. I heard a loud noise like a gunshot and then could hear the sound of air like riding with the window down. I looked around inside my car and didn't see anything so I pulled the shade a little from the sunroof and it was shattered.”

NHTSA complaint #11341312, filed 2020-07, 10,000 miles

Brakes: “The 2019 QX80 forward emergency breaking system (feb) continuously engages the brakes without warning or an obstruction. Always while a railroad crossing is in site, sometimes when a redlight is near but (green) with no vehicles stopped at it. It has also done it on an open highway & interstate at speeds of 70 MPH with nothing around. This causes a very real chance of being rear-ended, or starteling the driver into crashing.”
