Open the full vehicle complaint log (all categories)AFTER THE CAR HAS BEEN DRIVEN FOR 20 MINUTES OR MORE, IT STARTS REVVING ON ITS OWN. IT HAPPENS MOSTLY WHEN I AM ENTERING MY GARAGE. I HAVE TO STOP, BACK UP, THEN GO FORWARD TO GET IN BECAUSE I HAVE A SIDE GARAGE. I HAVE TO KEEP MY FOOT ON THE BRAKE TO KEEP FROM SURGING FORWARD. I HAVE ALSO HAD THIS PROBLEM WHEN STOPPED AT A STOPLIGHT AND HAVE ALMOST HIT THE CAR IN FRONT OF ME BECAUSE IT SURGES FORWARD FORCEFULLY. IF I CUT IT OFF AND RE-START THE ENGINE, IT STOPS SURGING. I MENTIONED THIS TO MY DEALERSHIP AND HE SAID THAT IF IT IS NOT DOING IT WHEN I TAKE IT IN, THEN THEY PROBABLY CANT FIND OUT WHAT THE PROBLEM IS. THIS HAS BEEN AN ISSUE WITH MY INFINITY FOR ABOUT ONE YEAR NOW.
I HAVE EXPERIENCE TWO OCCASIONS DURING STOP AND GO TRAFFIC WHERE THE ENGINE WILL REV UP AND ACCELERATE. ON THOSE OCCASIONS I HAD TO PRESS THE BRAKES HARD TO AVOID HITTING THE CAR IN FRONT OF ME. I ALSO CHANGED GEARS TO NEUTRAL. DURING BOTH TIMES I WAS IN STOP AND GO TRAFFIC MOVING FORWARD...NOT TURNING. I ALSO TRIED USING THE CRUISE CONTROL. WAS TRAVELING IN A TOLL ROAD IN MOTION. HAD DIFFICULT SETTING ONCE CRUISE CONTROL WAS ON... IT MYSTERIOUSLY SHUT OFF. THIS WAS NOT WEATHER RELATED AS IT WAS A HOT CLEAR DAY AND I WAS TRAVELING THE SPEED LIMIT OF 80.
INFINITI G37, AFTER WARM USUALLY MORE THEN 30MIN OF DRIVING WILL INTERMITTENTLY GO INTO LOW AND HIGH ACCELERATION ON ITS OWN. AS IF YOU ARE BRAKING WITH YOUR LEFT FOOT AND THEN GIVING IT GAS ON AND OFF WITH RIGHT FOOT. MY WIFE HAS ALSO DESCRIBED COMPLETE LOSS OF POWER WHEN THE CONDITION OCCURS AND SHE TRIES TO ACCELERATE. SHE FEELS IT COULD BE A DANGEROUS COMBINATION IF IT HAPPENS AT THE WRONG TIME. WE DID SCHEDULE FOR A SERVICE APPOINTMENT AND HOPE THIS WILL HELP OTHERS WITH SIMILAR CONDITION. *TR
