“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.”

“I was driving down the road and noticed the clutch wasn't feeling normal. As I shifted into 3rd gear, the clutch pedal stuck to the floor and wouldn't spring back. I tried pumping on it, then managed to get my foot underneath it to pull it up and then down shift. When I depressed the clutch again and attempted to shift into 2nd gear, the clutch stuck again and I was stuck in 3rd. I finally eased on the brakes and had to intentionally stall my car. I was lucky to have been on slow moving, lightly used road, or else this could have caused an accident. …”

“The vehicle has started to stutter upon taking off and shows signs of power loss. After much investigation, these g37s have a minor defect that causes the engines to run on low oil pressure. The part 'gallery gasket' is the culprit that causes these engines to, in bad cases, last only up to 100k miles. Everywhere online there are Infiniti owners talking about this gallery gasket problem and few of them have had to buy a replacement engine because of it. Infiniti has failed to come forward with a solution to reduce the amount of oil related problems in these cars. …”
