This is my second report for the same problem in the same vehicle. The first occurrence was in may, 2001. (see ODI id 561620) the most recent occurrence was 1/25/02. In this case, I was driving 30 mph and accelerated slightly to change lanes. As soon as I pressed the accelerated, it depressed to the floor of the vehicle, causing a dramatic increase in speed. I pressed the brake, but it was rock-hard and did not depress one bit. Remembering the previous occurrence, I shut off the engine and coasted to a stop. Only after I reached a complete stop did the brake pedal depress for me. I restarted the engine and it ran smoothly, so I drove to the nearest parking lot and inspected the ccruise and accelerator cables. They were clean and in no way kinked or appeared to have stuck for any other reason. The last time this happened, I drove to a local service shop, where my intelligence was questioned and the whole incident dismissed as driver error. Took the vehicle to the dealership shortly thereafter, and was told that since they could not duplicate the problem, they could not fix it. I fear that I am stuck with an otherwise nice, low mileage deathtrap. It is the primary means of transportation for (pregnant) me and my 4-year-old. Must one or all of us be injured or die for this to be taken seriously? if I choose to sell it, I certainly feel a moral obligation to let any potential buyers know what has happened. Please help me! and this time, please send the signature form (I did not receive one last time) that allows you to report this to the dealership and manufacturer.
