2014 Infiniti QX60 Vehicle speed control Problems

“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. …”

“I have been having issues with my Infiniti QX60 since I purchased it 09/2014. There is a problem with it accelerating. I would press on the gas and it wouldn't give me the acelleration that I would expect from this car... It is very sluggish. I have told this to the dealership on several occasions since 2014. Every time they checked it, they said there wasn't a problem. One time, I received the same car as a loaner car while they worked on my car, and I could clearly see that there was a difference in the way that car drove versus mine. The loaner car drove better than my car. …”

“My wife purchased 2014 Infiniti qx-60 SUV on january 23, 2014. She noticed when setting the intelligent cruise control at 40 MPH the vehicle will pick-up speed going downhill. Depending on the length and grade of the hill the vehicle will increase as much as 30+ MPH. When I drove the vehicle I noticed the engine RPM's remained at, 1500 RPM's, but the speed would continue to increase. On march 18,2014 I made a visit to dealership and met with the service consultant and the service manager. I explained what I experienced and asked if they could look into it for me. …”

“On two separate occasions,the gas pedal on the car got stuck in the down position causing the car to accelerate uncontrollably. The first time was while accelerating onto the highway. When I let off the gas pedal, it stuck in the down position and I had to manually disengage it with my foot. The second time on 3/7/2015 at 2050, my wife was driving at a steady speed of 65 MPH when the gas pedal went down on its own causing the car to accelerate to approximately 85 MPH before she was able to disengage the pedal. There was nothing underneath the pedal to cause it to get stuck either time. …”

“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.”
