While the engine was on and the car in drive, but stopped with my foot on the brake, the engine unexpectedly revved up to about 6000 RPM. The first time was about 2 months ago, in a parking lot. I thought perhaps I had inadvertently pressed the accelerator while my foot was on the brake. Two days ago it happened again. This time I had driven about half a mile, stopped the car for a couple of minutes, and when I started again the engine raced once it was put in gear. I had to turn it off and then on 3 times for it to come back to normal. Yesterday I drove about one mile to a traffic light, and while I was stopped waiting for the light to change the car started to rev high and move into the intersection until I moved it out of drive. I had to shut off and restart for it to return to normal. About 15 or 20 more miles of driving and a half dozen stops, it happened again while I was leaving a parking space. When I got home I connected my code reader, there were no codes. It is now at my mechanic, but the problem has not happened for them yet.

On June 26th 2013 the vehicle experienced total loss of power while driving and there was a corresponding strong electrical burning smell. Fortunately the vehicle was able coast off the main road and the family was able to exit safely. No fire started but car would not restart. Car was towed to Nissan where they identified the problem as the ground battery cable being pulled off the transmission mounting point. The battery cable was replaced with a modified design that prevents this from occurring, the damage caused by the ground wire breaking was $2,871 which included the ground wire, 6 ignition coils, ECM, ipdm and labor. There is a tsb ntb06-075 for Quest models 2004-2007, however the 2008 had the same design as indicated in the tsb. The vehicle had been in at St charles Nissan as recently as 6 weeks earlier and the 27-point Nissan inspection had been performed which was supposed to included the battery cable. No issues were found with the battery cable so either the inspection was not thorough or there was catastrophic wire failure caused by excessive drivetrain movement. The vehicle smelled like it could have caught on fire which it unfortunately did not. Losing all power instantaneously without any prior symptoms or service engine lights is concerning for this could have just as easily happened in an intersection or where the vehicle was not safely able to avoid other vehicles. The damaged parts have been retained in case NHTSA would like to inspect.
