Consumer called complaining about having problem with sudden acceleration from the transmision while driving the vehicle. Is technical service bulleting on this problem #sb01-05-s001. Please provide further information. Mr
Motor will rev up when sitting still at a red light and try to lunge forward. I have even had it go 35 miles an hour without my foot even being on the accelerator. I have had my truck to the dealer 3 times now and they keep saying they can not find anything wrong. Unless they can see the vehicle do it they can't fix it. The check engine light does not come on and they say until that happens they don't know what is wrong. Dealer refuses to keep vehicle and drive it until it does it so they can see it. They make it sound like I am making this up. There is a problem and it needs to be fixed. I do not want to be responsible for a accident that I have no control over. The state police says it is illegal to drive a unsafe vehicle on the state highways. I owned a brand new vehicle that is illegal for me to drive on the state highway and isuzu won't do anything about it. I have contacted isuzu corporation as well as been back to the dealership 3 times and it is still doing it.

Related recalls
Vehicle speed control: cables
- What is wrong
- On certain sport utility vehicles, the accelerator cable can stick so that the engine speed will not immediately decrease upon release of the accelerator pedal.
- Risk
- This can cause the accelerator throttle cable to delay RPM and vehicle speed reduction for several seconds after the accelerator pedal is released, which in turn, can lead to a crash.
- Remedy
- Dealers will replace the throttle cable rubber boot. Owner notification began on may 24, 2004. Owners should contact isuzu at 1‑800‑255‑6727.
