Example complaints

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

“My wife opened the rear liftgate using the outside electronic door switch on the liftgate. The liftgate electrically fully opened. My wife started to load items into the rear of the SUV. The door electrically closed on its own. The door struck the back of my wife's head before she could get out of the way. The door did not stop or open automatically, or detect an object in its path. She tried to reopen the liftgate using the switch, and it raised about 5 inches and then immediately shut. She brought the vehicle home and told me what happened. …”

“I was driving down an empty road, no one in front of me, beside me, or behind me and the automatic braking system applied itself and slammed on brakes abruptly and beeped twice, without any prior warning or obstruction, causing the car to jolt into braking. I have contacted the dealership regarding this and they are looking at the precollision and emergency braking system next week. There were no prior warnings this braking was occurring. …”

“The power liftgate (automatic trunk) system on my 2019 Infiniti QX50 malfunctioned. After fully opening, the liftgate unexpectedly closed on its own without any warning beeps or resistance detection. This poses a severe safety risk. The heavy door struck my head, causing a physical injury (a severe bump/contusion). The vehicle and the affected components are available for inspection upon request. This problem has not yet been inspected, reproduced, or confirmed by a dealer, manufacturer, police, or insurance representatives, as I am reporting this dangerous safety defect immediately. …”

NHTSA complaint #11754847, filed 2026-08

“There is a continuous issues with my battery dying. There are multiple malfunction lights showing, particularly the rear collision light. The check engine light is also showing, and I have had an oil change recently. The car breaks on its own. While backing into a space, the steering wheel would not completely turn right until I straightened up the car. Finally. I have had my driver's side car seat repaired three times by the dealership. It works sometimes and not others. Any suggestions on any or all of this would be helpful. Thank you.”
