Lexus RX300 owners have reported 2 problems related to transmission pump (under the power train category). The most recently reported issues are listed below.
Drove my Lexus Rx300 to lake tahoe. It was 28 degrees as I entered the tahoe area. The transmission begain to slip, not maintaining engagement. I was able to get to the hotel but about an hour after registering I tried to drive and the transmission would not engage. It was now 24 degrees. I tried again in the morning but it still would not engage and now there was a whirling sound. I had it towed to the Lexus dealership one hundred miles away. The transmission failed due to the front-side transmission pump. Lexus/Toyota will not replace the part. Since it is an internal transmission problem they will only replace the whole transmission. Lexus policy. It is a 15 hour repair. Even if it were possible to replace the pump it would have taken more hours to repair. The contact was advised by the dealer prior to purchasing it that it was in impeccable condition. An inspecting authorized mechanic also stated that its rare to see a vehicle in as excellent of a condition. An SUV should not have a problem in slight extremely cold conditions. The service technician stated that the transmission failure isnt uncommon if they are in extremely hot or cold climates. The contact stated that there is a design flaw. He has never had to change the transmission fluid as frequent in his previous vehicles. The contact is aware of the safety risk involved. It cost $4700. 00.
