Runaway acceleration. Three times now in the last two weeks the RPMs went to maximum redline without my foot on the accelerator pedal. Fortunately all occurred when I was at very slow speed and either in a driveway or a parking lot. Each time I immediately put the transmission to neutral and shut off the engine. For the first occurrence, Restarting the engine all went back to normal. But for the second instance, two weeks later on restart the engine again instantly went to maximum RPM (deep redline). On a second restart, with additional delay before attempting a restart, the problem cleared. I took the car to a mechanic and they said no error diagnostics were recorded. On test drive he said he noticed some brief unexpected surges. He said for liability reasons no way he would work on the car. No warnings, no instrument indications, car does not seem to "know" throttle is at max redline.

Brought car in for any state inspection and found the front suspension crossmember to 100% rusted thru. Car failed inspection. Found out that this is a common failure on this model of infiniti. In addition replacement part is on national back order. So on top of a poorly designed part they are unable to keep them in stock.

The contact owns a 2008 Infiniti G35. The contact stated that while at a complete stop, there was an abnormal popping sound as the rear-end of the vehicle lowered to the pavement upon depression of the accelerator pedal. Upon inspection of the vehicle, the contact discovered that the rear subframe was detached from the vehicle. The contact initially towed the vehicle home and then to an independent mechanic. The mechanic discovered that the rubber bushings that held the subframe was not a strong reinforcement to hold the subframe in place. The contact notified several dealers about the failure and each informed him that they were unaware of such a failure. The dealers informed him that he had to purchase an entire new subframe which could contain the same defective rubber bushings. The manufacturer was not notified of the failure. The vehicle was not repaired. The failure mileage was 130,000.

MY CAR HAS BEEN STALLING WHILE DRIVING AT LOW SPEED. SEVERAL WARNING LIGHTS COME UP (CHECK ENGINE LIGHT, SLIP LIGHT, BATTERY LIGHT) AND THEN THE ENGINE SHUTS DOWN COMPLETELY. UPON PLACING THE CAR IN PARK, I AM ABLE TO RE-START IT. THIS IS A MAJOR SAFETY ISSUE. I BELIEVE MY CAR IS PART OF RECALL NUMBER 03V455000 - ENGINE AND ENGINE COOLING. HOWEVER, MY VIN IS NOT PART OF THE RECALL, BUT I AM EXPERIENCING THE SAME ISSUES ASSOCIATED WITH THIS RECALL. THIS NEEDS TO BE RE-ADDRESSED. I HAVE CHILDREN, AND I AM WORRIED THAT THIS ISSUE CAN CAUSE AN ACCIDENT, ESPECIALLY WHILE I AM DRIVING ON THE FREEWAY. I HAVE SEEN VARIOUS SIMILAR COMPLAINTS RELATED TO THIS ISSUE WITH INFINITI.

PASSENGER SEAT OCCUPANCY SENSOR FAILURE. THIS DISABLES THE AIRBAGS FOR THE FRONT PASSENGER. COST TO REPAIR APPROACHES THE VALUE OF THE CAR ($6K-7K). SEEMS TO BE A COMMON ISSUE WITH THIS VEHICLE.
