2008 Infiniti G37 Vehicle speed control Problems

“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. …”

“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.”

“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.”

“2008 Infiniti g37s with a 5 speed automatic transmission with 41,000 miles - I was entering the freeway going about 55 MPH and there was an 18 wheeler in front of me having a hard time picking up speed. Before passing, I tapped my brake, downshifted from 4th to 3rd gear with my left paddle shifter near the steering wheel and proceeded to get in the lane to the left of the merging lane onto the freeway. I was halfway in the lane and hit the gas but there was no response for 3-5 seconds. …”

“On october 23, 2009 I was driving in a parking structure with my Infiniti G37 2008 and a passenger. There were several parking spaces on the fourth floor. The parking structure was very busy and slow moving. I coasted into the parking sport since I was driving at a crawl. When I touched the brake light to come to a complete stop the car surged forward with such a force that it hit the wall that was approximately 3 foot in front of parking curb. If it hadn't have been for the wall the car would have gone over.”
