I have a 2006 Lexus RX330 AWD I have the for few months and I have problems with the transmission (the car don’t shift properly). The car make a late shift between 1rs and 2nd gear and some times hard shift in 3rd gear, any body else have the same problem?
The RX was the top-selling vehicle in its class during that generation, and still is a top seller. To answer your question, there is not a well-documented problem with the transmission. Those crossovers are among the most reliable ever built by any automaker. Here is a quick peek at the few recorded issues with the vehicle. There are some TSBs related to the transmission of the RX from that year. It would be worth speaking to a dealer to find out if any apply to your specific VIN (and have not been implemented already).
