NHTSA complaint #11164528, filed 2019-01, 40 miles2015: “I have always any lights on my truck / now cheek engine light on for ccv speedo rotor / sensor nox all most $3500 doller need fix / I don't have / before I lot money put on repair/”
NHTSA complaint #11154820, filed 2018-11, 395,600 miles2018: “Automatic emergency braking is an absolute danger to the motoring public and needs to be eliminated immediately. I am sick and tired of engineer's who don't know their ass from a hole in the ground designing bullshit that doesn't work. Far too many false radar returns and unwanted hard stops to be of any use. I do not own this vehicle but if I did the first thing I would do right after I pull the fuse for the lane departure warning would be to isolate and bypass aeb. This will be done on any vehicles I purchase in the future and I do not care what the law states about doing so”
