Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“While driving 80 mph down the highway my brand new vehicle shut off completely, the entire car lost power. In another instance I was going around a roundabout and my acceleration completely went out, my son was in the back seat and another car had to jump the curb to avoid crashing into us. I met a woman in the dealership who has been waiting over a year for her recalled tow hitch to be fixed. When it rains or snows the forward safety systems shut off and the alert repeats extremely distracting on your dash, like sounds, red flashing lights, over and over again. …”

NHTSA complaint #11529228, filed 2023-06

“While I was traveling 70-75 mph the vehicle had a sudden loss of engine and battery output performance and I began losing speed. There was a very rapid decrease in speed, and no warning chime activated per manual. “Check Hybrid System. Stop Safely, triangle warning displayed.” The vehicle would not accelerate despite pressing the gas pedal all the way to the floor and had to be coasted off the interstate through three lanes of traffic to get to the shoulder. No fault indications were present in the Bluelink app despite warnings present on the dash. …”

NHTSA complaint #11477826, filed 2022-08

“This vehicle hesitates to a dangerous degree when trying to accelerate from a stop or rolling stop. When pressure is applied to the gas pedal, the vehicle will not accelerate until nearly a whole second later. This delay in response has created dangerous situations where merging onto a road in a predictable and smooth manner is crucial (i.e. turning right at a red light, a 4-way stop). I did not notice this problem during my test drive, but now at almost 10,000 miles, the problem has become more pronounced. No warning messages in the gauge display. …”

NHTSA complaint #11463716, filed 2022-05

“While traveling 70 mph the vehicle had a sudden loss of engine and battery output performance while driving and began losing speed despite the accelerator being fully depressed. There was a very rapid decrease in speed, and no warning chime activated per manual. “Check Hybrid System. Stop Safely, triangle warning displayed.” Observed battery indicator rapidly deflecting left and right. The vehicle would not accelerate and had to be coasted through four lanes of traffic to get to the shoulder of the highway. …”
