Infiniti recalled Q50, Q70 vehicles built between 6 April 2010 and 28 July 2014. Under certain circumstances the throttle position sensor may send an error signal to the Engine Control Module (ECM). The dealer will install new software of the ECM. You won't usually pay for it.1
What’s Wrong
Under certain circumstances the throttle position sensor may send an error signal to the Engine Control Module (ECM). As a result the ECM may not operate as intended and the vehicle may accelerate gradually without the driver operating the throttle pedal. However this acceleration can be overridden by application of the brakes.
