| Description of the problem | I have 2004 awd sienna. A week ago, when i started the car in a freezing morning and drove in subdivision road, the slippery light and beep came on and the brake acted here and there on the wheels. At the very beginning, i thought the road was slippery. But it was not the case. There was no way my van was skidding all the time. I was only driving at 10 mph. Then i realized the vsc was wrongly activated. Whenever i get to more than 10mph, vsc got activated and broke the speed down to 5 mph. I could only drive at 5mph without getting vsc activated. Then i realized i could not drive this van on the road. I parked it back in garage. The next day, my wife drove it out of the garage and got the same symptom. We put the van back to garage for another 3 days before i was about to call a tow truck to tow it to a dealer for examination. I tried it again. Miraculously, the problem went away. I went to the dealer and talked to the service adviser, he said he knew nothing about the problem (recall etc.) and asked me to bring the van back for service once the problem happens again. My van appears to be working correctly now, but i dare not drive it far away from home. I know the problem is not gone. It will come back at the most inconvenient time. I do not want to be stranded in a snow storm at -30 degrees f that i can only drive at 5mph (that is what the weather is like here in chicago at this time of the year). I do not want to be thousand miles away from home when the problem happens again. It would be nightmare if vsc wrongly comes on at high way speed. |
