Two problems related to vehicle speed control have been reported for the 2003 Lexus GX470. The most recently reported issues are listed below.
It is possible to simultaneously depress the gas pedal when braking, this causes sudden uncontrollable acceleration I reported the incident too Toyota and requested upgraded ecu software that disables the gas pedal while braking Toyota refused to provide a simple software fix my wife is a witness.
I was traveling west on a two lane paved road (sutton road) near sutton school. Weather was snowing and road conditions slippery when my accererator failed to return to idle position. I applied brakes as I was approaching a vehicle in front of me traveling in the same direction. The electronic stability control failed to maintain straight direction as per design intent and manuals. Front began sliding to left and rear of vehicle began sliding to right. I ncreased brake pressure and steered into th skid , to the right. I was able to miss the contact with any other vehicles and or damage any property , but did end up sliding into a ditch off of the road. With the impact resulting in the death of my service dog . As I am handicapped. No damage to my vehicle , but no I am virtually immobile with the loss if my dear service dog.
