Example complaints

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

“Did not bring back the gear to park and pressed the start button. Left the vehicle not hearing the very weak signal. Wrote to manufacturer about this design issue. They did not care, even they responded that it is the way it is designed. Any driver with european or manual gear background will make the same mistake. The car was positioned on a slope, in a garage after I arrived at my destination. An agent had the reflex to jump in the car (I left the door opened) and stop the vehicle. …”

“While driving on freeway, clutch got stuck. I was unable to switch gears. I ended up stopped in the #2 lane and could not move. I had to push my vehicle to the side of the road with the help of another motorist. I finally got the vehicle back into gear by pulling up the clutch using the top of my shoe. After I resumed driving, the clutch got stuck again. I brought the vehicle to the dealership and informed them of the issue. I also opened a file with Infiniti USA. I have video from when my car was disabled showing that the clutch was stuck and vehicle could not be put into gear. …”

“This vehicle has a generic problem with acceleration: under some circumstances, especially at low speed when the accelerator pedal is pushed hard for rapid acceleration, the car will not accelerate, but hesitate, for almost 2 seconds, before finally accelerating. In some circumstances, this can be a serious safety issue: merging into (rapidly moving) traffic, seeking to cross an intersection, striving to avoid inattentive or careless drivers, etc. I have complained about this repeatedly to the dealership. They say it is a transmission issue, but they admit it is a known issue. …”
