2014 Infiniti QX60 acceleration problems

Filed Jun 19, 2025 · Acceleration, Fuel system · FL

This vehicle started shaking and juttering at a lower speed and made it very difficult to drive. Then I could accelerate and it would not go faster. I took it to a repair shop and they were getting CVT codes for the transmission. I looked online a found that many other people had these same issues as well as a Class Action Lawsuit that was settled a few years ago for 278 million for these problems. I was never informed that this CVT was a problem and could have it replaced from Nissan for no charge. I am not sure why Nissan would allow an unsafe transmission to be installed into a vehicle that would make the car unsafe to drive.

The car does not accelerate or accelerate with jerky motion. Occasionally, the vehicle disengaged out of drive mode and would not accelerate. There seems to be some transmission issues as the vehicles is making jerky movement upon acceleration. Almost cause accident on a turn as it could not move forward out of cross traffics!

I bought a 2014 INFINITI QX60 and after one week, my vehicle started to jerk after resuming from a stop sign or stop light but was just annoying at first. Later that day, the check engine light came on and I took it to auto zone to get the code which displayed "P1715 - Input Pulley Speed Signal" and secondary DTCs were P0776 (Pressure solenoid B performance/stuck off. When I am driving, I cannot make it a mile without having my RPMs skyrocket and my vehicle become inoperable and makes me turn my flashers on and find a place to pull over, shut off my vehicle, and restart it. This repeats over and over and over if I continue to get to the grocery store for essential needs but it is not safe to drive and will for sure cause a collision if it keeps happening. There are so many issues with this make/model and needs to be addressed for the safety of others on the road and myself/children as it is unexpected and very scary.

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.

When accelerating the vehicle begins to shudder and it does not accelerate in a timely fashion. While driving on the street or highway the car does not gain rpms and begins to what best can be described as coughing and shaking. Changing gears from drive to neutral or reverse also takes the vehicle time to make the change.

The car shudder when I stepped on the accelerator. I was told by the infiniti repairman that it was because of the transmission. Checked online and found: the vehicles infiniti qx60 2014 are equipped with continuously variable transmissions known as the jatco cvt8ht that were allegedly defective before they were even installed in the vehicles. Never got a phone call from inifiniti for inspection the possible problem.
