| Description of the problem | We have owned the sienna for 4 years and 53,000 miles without incidence. We have had it serviced by the toyota dealer and have had all scheduled maintenance. One afternoon, after driving the sienna all day, we pulled it into our driveway (which is on a slight incline) and placed it into park. After doing this, instead of the brakes being applied, the sienna rolled back as though it were in neutral. We brought the sienna to the toyota dealer who inspected it. They told us the pin that enables the brakes upon placing the sienna in park was completely shot and the entire transmission would need to be replaced. The service manager said he has never seen something like this before and that these pins don't wear out over time. The service manager also told us that you would only see damage to the pin if you were driving the car and then suddenly put it into park while moving at a high speed. The service manager contacted the offices of toyota corporate and had the case reviewed. It was determined by toyota corporate to be related to the warranty and they are replacing the entire transmission. |
