Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Inline ignition fuse keeps blowing while driving. The first two times were when I was turning, two other times were when it was driving on a state highway, one time after it just started, and another as I left my driveway. At times the truck will start when a fuse is replaced, at times it takes multiple fuse changes to get on the road. This results in the engine to stop and power steering to fail. There is no pattern in when it happens. …”
NHTSA complaint #11005155, filed 2017-07, 155,000 miles“On february 14, 2012 I was driving on a clean, dry, straight, and level road at 35mph. I was not accelerating, braking, or cornering. The alarm bell rang and the dash board display indicated traction fault, reduced power, service stability system . The vehicle dramatically reduced it's engine power to the point it could not be safely operated in traffic. It was impossible to accelerate with traffic, merge, or make a left turn.
