What owners wrote

A few complaints as filed, shortened and with personal details removed. The first ones are among the most serious reports for this model year; the rest are typical.

The brake pedal and accelerator pedal are close together. With my size 12 foot, it is easy to accidentally have my shoe on both pedals. The car has enough engine power to overcome the braking system, and lead to a collision. With the ABS and tcs (traction control system) on this car, I would like to see an interaction to limit power if the ABS is activated.

I was parking my 2003 infiniti I35 on the third level of a santa monica city parking structure when my car suddenly surged. I immediately put my foot on the brake and turned the car (I was heading into a wall). I held my foot on the brake until it finally came of a complete stop. The car hit the wall of the parking structure causing damage to the paint on concrete parking structure wall and major damage to the automobile.

The car loses power after a while and will just stop as if it ran out of gas. This has happened several times, otherwise the car is ok. The mechanic suspects it has something to do with the crank position or circuit board. There was recalls on this model in 11/2003 and 12/2003 that describe exactly what happens to my vehicle. This slowing down to stopping happened on a major expressway and I had to be towed. It also happened again in my street and driveway having to be towed again.
