LS/RXKevin

My wife was backing our 06 RX400h out of a parking spot in a strip center last Friday and went to put the car into drive when there was a (as she said a huge clunk) -she thought she hit something -and the car died. We have 44,000 miles on it. The dealer called me Saturday and said the inverter crashed. Fortunatly my wife was only 20 miles away. My wife had just returned from a trip to Dallas the week before after driving there alone. Wow would i have gone over the top if this had happened to her 400miles away. I am now very concerned about the reliability of this vehicle. Dealer said they modified the inverter and I would be getting one --on order now. I am considering trading this unit in on a conventional internal combustion vehicle. This is the third Lexus that I have owned and am for the most part very disappointed in their products. On my 04 RX330 the ECU on automatic lift gate was was intermittant --I had to print the solution from this site and convince the dealer to repace it.

I just took a road trip from Houston to Austin and back and averaged according to the computer 26.3mpg. I was running 70 mph most of the time and all highway. This was in a 330 with 16,000 miles. My wife drives it around town and typical readings are 18-19 mpg. We took it to Sacramento a year ago and had similar results. We did get some bad gas and mileage on the freeway was as low as 19 mpg. I noted that Chevron middle grade seems to give the best results. It seems that gas mileage is very sensitive to gas quality.

yes, I have been waiting for two weeks now I had to show the dealer this thread to convince him that there was an issue. Interesting how we have to train the Lexus service folks. This is the best forum. :( Kevin

You have got me on this but one suggestion is to find out from your dealer which O2 sensors are the same. Since you have a new one you might swap the similar sensors and see if you get a different code. I know this is a job but it only costs you your time. Codes seem rather difficult to diagnose and solve without proper equipment. You may have to work with your dealer or a reputable shop and pay for some diagnostic work.

Split--- More than you everwanted to know about O2 sensors. This may be of interest to others thus my 8 scans to get this below 100 K. I have already complained. Your all welcome. O2_Sensor.doc

Split--- Another pix to help you locate the sensor Main_O2_Location.doc

Split-- I am looking at the main O2 see attached again from my 94 manual. Take a look at the graph. I have not digested this but may help. The file sizes for this site at 100 K make it a challange to size images to pass. I have more detail on the O2 sensor and can pass it to you as well. The main sensor is front most sensor.

Maybe this will help with your Code 25 issue. This is from my 94 LS manual and is probably applies to your 91 as well. Good Luck. Keep us informed. If I can help further let me know. Kevin Code_25.doc

This has been a random problem with my 330 and the only pattern that I have found so far is that if the rear hatch is not opened for a few days then neither the remote or the dash buttom will open the hatch. If I open the hatch manually and close it everything works again. This is an obvious problem as there have been others commenting on it. We have all had our cars for many months. I am still trying to figure out the pattern. My wife and I are going to wait for the next failure and drive directly to Lexus for the second time to report this problem.

I just bled the brakes on my 94 LS and tried a hand pump up vacuum rig that I bought from Griots some years ago it just sucked air bubbles from around the bleder valve threads. Use a second person in the driverseat and pump the brakes, the old tried and true method works best. I used Valvoline synthetic. Yes, pass rear, driver rear, pass front and then driver front.

You can change the filter with out affecting the oil in the pan. Obviously you have to replace the oil that is within the filter and that that drips when the filter is removed maybe a half a quart. I do not know about you but I take off the plastic wind shroud when removing the filter. This way I can clean up after the filter change. :)

I'm in Clear Lake area. Sure to bump into each other here. Good luck.

This is an 94 LS manual picture hope this helps. egr.doc

In most major cities Porter Cable has a store and they sell rebuilt units. I bought one for around $100 dollars a couple of years ago. They are the greatest variable speed and foam pad can be purchased from Griots.

OOPS! to be clear the first filter should drop out the second (north most) needs to be coaxed south over the opening to be removed. They will have to be bent slightly to avoid interference with the floor.
