I am reporting a serious safety failure involving my 2014 Infiniti QX60 Hybrid (VIN: [XXX] ), tied to Recall R21B4 / the federal safety agency 21V‑774. Although the recall was marked complete before I bought the car in 2022, the defect — sudden loss of power — occurred again while I was driving at highway speeds. Infiniti is refusing to assist due to age/mileage, despite clear evidence the recall fix was ineffective or incomplete. Diagnostic codes confirm hybrid system failure (P0A08, C1A1A, C1130). I am requesting a full investigation into Infiniti’s handling of this recall and a resolution for my unsafe vehicle.

While driving on highway loss of power and transmission, feels as tho it can't shift and rpms or out of wack. Even after the transmission was replaced last week by infiniti due to the recall, I'm still having the exact same problem.

While driving my car losses normal speed and stops responding to me trying to accelerate even after I hit the pedal all the way to the floor, car keeps slowly moving but doesn't pick up the speed. Sometimes its jerking on its own and do not respond to my pressure on the gas pedal. Seesm to be realated to similar issue that they have with q50 cars "engine control module (ECM) may temporarily lose a signal from one of the engine management system's throttle position sensors (tps). If this occurs, loss of power followed by sudden unintended acceleration can occur. Due to a software malfunction, the engine may suddenly lose then regain power, causing unintended acceleration.

The CVT transmission, whines super loud and slips like when your foot is down sometimes you lost power completely and wont shift right until you lift foot up and wait a while. Very dangerous if you have fast moving cars behind you and your SUV craps out and stops. I took it to the bennet allenton infiniti while under warranty which expired 2 months ago and they told me a CVT tnasmission is always moving. I explained that I know the difference between an auto transmission and a CVT and how they work. This problem is not normal operating for a CVT tranny. So again in the middle of driving in traffic while accelerating normal, the pedal goes to the floor and the car stops accelerating, so you are slowing down drastically until you lift up foot and wait until it wants to catch or shift.
