2003 Infiniti G35 was turning into parking stall at about 5 mph when the car suddenly accelerated without the accelerator pedal touched. Brakes were not used with sufficient force to stop the car. Car jumped curb, traveled fifty feet and hit a tree.

This is a further complaint relative to complaint 10047159 related to a new Infiniti G35 with less that 2000 miles on it when three incidents occurred. The incidents involved three occasions in which the car suddedly and unexpectedly accelerated to very high speeds without a action by the driver that should cause such accelerations. In two of the cases the car was in speed control; in one it was not. 2 of the cases: car in speed control at 60 miles an hour, foot well away from accelerator. Car suddenly accelerates full throttle to 90 miles an hour before very severe braking can bring car under control. Not only does stepping on the brake not take the car out of speed control, it does not significantly slow car as car continues to accelerate. Second occurrence involved car in speed control at 50 miles an hour. Same thing happens but I was not able to stop car as it rapidly accelerated and finally had to shut the ignition off and drift to the side of the road. Car was taken to dealer (Infiniti of denver) on 11/14/03, and returned to me (car is actually registered in my wife's name, lois ringer) over my very strong objections on 12/1/03, with the statement that the dealer and Infiniti engineers were unable to replicate the problem and therefore they would not investigate the problem further, based on direction from Infiniti. The problem only occurs sporatically, so it is not surprising that they did not replicate the problem in the minor testing they did. A quick interaction with one bulletin board on the internet to see if any other owners of G35s were having the same problem revealed three other drivers having very similar problems. A letter was sent to the president of Nissan America (which owns Infiniti) on 11/14 to no avail. The similar problems of the other three owners are documented on the edmonds. Com website.

When vehicle is at a complete stop with feet depressed on the brake pedal, and air conditioner is on, vehicle will suddenly accelerate. Brake pedal has to be depressed very hard to stop vehicle. Cause of sudden acceleration is undetermined.
