I have a 1999 Lexus RX 300, and have had about 71K miles on it, and recently had the car breakdown about 240 miles away from my home. My car would shift to neutral gear at speeds higher than 45 mph, requiring me to turn the ignition off and back on to drive ( only at lower speeds). Any one seen this? The local dealer at the place where my car broke down wants to replace the entire transmission for 4K!!
We were not too sure about the cost and timeframe she proposed, and got it towed to our city for our local dealer and Lexus cust service to take a look at. I am surprised to see that RX300 had so many transmission issues, and am hoping Lexus will take a look at all the anguish the owners are experiencing and take some positive action.
Has anyone lodged official complaints with Lexus customer service, and how was the response? I Have reseacrhed on the net and saw many complaining about transmission issues with '99 RX. Shouldn't this be a recall? I was a die-hard Lexus fan, but now I am very disappointed with the transmission dying so early.
As of 2004 the RX330 uses DBW, e-throttle, to prevent the engine RPM from rising, regardless of accelerator pedal position, while the transaxle is changing gears. With the advent of the RX300 Lexus began using a few new techiniques to improve FE in the range of 9.8%
Those techniques involved quicker, earlier upshifts, use of the O/D lockup clutch in lower gear ratios, and lastly, shifting into neutral as you coast down to a stop and then only shifting into 1st after coming to a full stop. Given that all this often resulted in the transaxle being in the wrong gear when/if the driver suddenly decided to go from coastdown to acceleration, or from low speed cruising to accleration, the likely result was a doubling of wear rate of the transacxle's clutches.
