2003 Infiniti G35: jerking or lurching

Filed Nov 30, 2012 · Brakes · 107,000 miles · GA

Coming to a stop on an interstate exit ramp, the car slowed to about 25mph with normal braking at which time the brake stopped slowing the car. I pressed the petal on to the floor and the antilock brake mechanism stopped the car in about 150 feet. Just before stopping, the car lurched forwards a few times. I had not been repeatedly braking on the interstate: a cause of brake fluid boiling which has been offered as an explanation of this failure in other incidents with this and the 350z.

I was driving my sister-in-law to macarthur airport in islip, ny. We came to a red light just outside the airport. I took my foot off the gas pedal and put it on the brake pedal, but I felt the car was still trying to move as though there was another foot on the gas pedal. Fortunately it was not that much thrust involved. I kept pressing harder on the brake, but the car kept inching forward at about 2 MPH. I wasn't sure if I could stop before hitting the car in front of me (fortunately I always leave lots of room). So I put the car in neutral. Because my foot was pressed very hard on the brake, there was a sudden jerk as we stopped suddenly. Luckily we all had our seat belts on. It has not happened since. I don't think there is anything wrong with the pedal. Maybe there was some type of electrical interference from the airport that messed with my car's electronics?

Tl*the contact owns a 2003 infiniti g35 sedan. The contact stated that the transmission failed at 45,000 miles. In addition, the brakes failed on the vehicle and were replaced several times. When the vehicle was started, it would jolt and jerk on its own. The dealer stated that the transmission was slipping and needed to be replaced. He assumed that the repairs could be made under the extended powertrain warranty; however, the manufacturer stated that the warranty did not include the fly wheel or the clutch component of the transmission. The failure mileage was less than 45,000 and current mileage was 69,800.

Copy of what I sent to infiniti via infiniti.com: my 2003 infiniti g35 has been into the orlando infiniti dealership twice for a transmission issue. In the last trip it was at the dealer for eighteen (18) days and the issue is still unresolved. After speaking with the service manager, john, I was told that he called infiniti technical support who stated that the problem is considered normal operation. I would like to know under what circumstances a transmission jerk at around 40 MPH is normal, as I have never driven a vehicle that has done this, including the 2007 g35 courtesy car that infiniti loaned to me. If this is considered normal operation, would not all infiniti vehicles exhibit this? On the website there are eight (8) pending complaints of owners experiencing transmission problems, and two (2) technical service bulletins listed. Also, after speaking with the service manager, john, it has come to my attention that there are other g35 models at this dealership experiencing the same issues; and theirs are also still unresolved. I am asking that I be treated the way a customer should be, as this situation has been handled very unprofessional. I have documentation of all work orlando infiniti performed and I would like this to receive immediate attention as I do not feel safe in a vehicle with transmission problems. Thank you.
