Lexus RX 330 Maintenance and Repair



  • I have an '05 RX330 and recently the Nav system stopped working properly. The display reads "Can't find DVD".
    This doesn't happen every time I try to use the Nav system -- happens sporadically.
    I took it to the dealer and was told that when this happens the (whole) Nav system needs to be replaced. As you might guess, it's a very expensive item, and with labor the total is even higher.
    Has anyone had any experience with faulty Nav systems in their RX330? What was the fix? Any input or suggestions are appreciated.
  • Can anyone recomend a good independent Lexus repair shop in the greater West Chester, PA area? Wilmington/Newark DE area would also be considered.
    I'm looking for a mechanic that does good work at a fair/reasonable price (and doesn't replace parts that don't need replacement). Basically, a shop with a reputation for good work and integrity. (Dealers need not apply).

    You may have water in the wheel well for the spare tire.

    The DVD player is on the right side, to the right of the tire jack. You can easily eject the DVD and clean it.

    In april of 2005 I had both headlights replaced in my 2004 RX330 due to accumulation of condensation inside the headlight assembly. This was done under warranty. I am now faced with the same problem on the driver's side headlight. Of course its no longer under warranty. Knowing the stock answer I would get from the dealer I spoke directly to Lexus seeking help in replacing the assembly. I understand that dealers quote about $1700.00 to replace one assembly so its expensive. I have stayed away from the local dealer because of the atrocious service I received in 2005/2006, which I documented in a letter to Lexus. As expected Lexus checked with the dealer to see if I was a good dealer customer before commitiing to an answer. As expected they declined to do anything.

    I am very disappointed since of all the auto manufacturers I thought Lexus would stand behind its product when it appears to be a recurring problem. I since discovered that several other owners have the same failure. My conclusion is that these headlights have a residual defect. Its too bad that Lexus will not take steps to maintain brand loyalty when they are faced with what is without doubt a latent defective product.

    Let me know if anyone in this forum has had to deal with the same issue.

    I too had a defective headlight assembly and it was replaced under warranty. Just passed 50K so am very concerned about the other one going bad and getting screwed for $1,700.

    I just returned to Virginia from Florida and had a Thule cargo carrier on the crossbars of the luggage rack. I drove 10 hours straight through and it rained the entire time.
    When I took the Thule carrier off about two days later I discovered that the cross bars could not be moved. When I pulled up on the little lever that releases the pins on both sides of the cross bar the bar would not budge. I tried a few squirts of WD 40 on each of the four levers and problem was solved. Not sure whether the weight of the cargo caused the problem (I was very careful to not exceed max weight listed in owner's manual) of if it was due to 10 hours of heavy rain or a combination of both.

    Add me to the list of 2004 RX 330s with air suspension problems. I got the same blinking on and off light that coyera reported. Mine occured at 40,000 miles and 5 months after the warranty expired. My RX has been far from flawless. Very few RXs with air suspension were sold so if there are several people reporting problems then satatistically the percentage of failure could be high. This may be my last of 6 Lexus products and certainly the last with an air suspension. I will also never buy a new model in its first yearafter a major revision, like this 2004 RX or the new 2010 RX. I'm tired of being Lexus' rolling testbed.
  • I have a 2004 RX 330, and had a headlight condensation problem as you describe. I placed an electric space heater on a step ladder about two feet from the headlight, and heated the assembly with low heat for about 1.5 hours. The condensation disappeared.

    I have also had the moldings from my rear quarter windows blow off. The first time it happened, I had the window replaced (expensive). This time, after the weather warms up a bit, I am going to glue the molding on.

    I had the pump on my air suspension replaced at about 40K miles.

    I am still a fan of Lexus.
  • Re #1662 My headlight 'repair' with heat was short lived. The moisture is back. My dealer told me it will cost $1K to replace now, or $1700 if the ballast goes bad.

    The solenoid on my air tank (air suspension) is noisy. Est $975 to replace. This is the second major repair on the air suspension system @ 64K miles.

    The owner's manual says the gas tank capacity is 19.5 gallons. On the only road trip that I took since we bought in Dec, the low gas light was on for some 20 miles, thinking it had to be dry, I was able to put only 17.3 gallons in it. Do these RX330 AWD really hold over 19 gallons?

    You can get used HID non-AFS or AFS type headlights on E-bay for about $150 each. The problem with these RX's is that you have to take the bumper cover off to get to the headlight.

    If you keep getting too much condensation in the headlight, you could loose the bulb too.
  • I just bought a lexus RX 330 2005 with 60,000Km (certified by the Lexus dealer) . I find it has wierd AC behaviour. It was very hot two days ago, around 33 degrees celsius (90 F) and the AC was fluctuating between very cold air and mild cold all the time. The cold air output was not sufficient to cool the car confortably. Both sides were on LO and I tried recirculate and no recirculate and the effect was the same

    I pushed the fan to maximum speed and heard a distinctive groaning noise
    coming from the fan. (When I shut off AC the fan noise remains there so no link with the AC )

    AC and fan are not covered by waranty in on certified lexus in Canada
    I do not know what is going on. and before I go to the dealer for a costly
    repair could you help me if any of you have a RX330 with those three questions:

    1- When your AC is on do you feel the compressor is constantly starting and stopping and the air outlet temperature is constantly fluctuating from very cold to "not so cold" .

    2- in very hot weather do you have enough cooling in the cabine (i suppose yes since i did not see any complaints in the forum on that)

    3- When your fan is at the highest speed , do you hear a groaning noise , or is it really silent. Noise is distinctively higher and groaning than when fan is at low speed. (This is independent from the AC on or off)

    Check that the pollen filter is installed otherwise something may have fallen into the squirrel cage blower and is the source of the blower noise. The sunlight radiation sensors, left and right, can, will have, a significant effect on the level of cooling routed out of the ducts.

    For quick cooldown on a hot day I always turn the system to max cooling, 65F, and adjust the fan for an "acceptable", lower, noise level.

    You can increase the A/C cooling efficiency significantly, and get a slight gain in FE, by blocking the hot water flow to the heater core during the summer.
  • Thanks wwest
    I will check the pollen filter I think it must be recheable through the glove box
  • Been having a rattle noise in the back of the car
    Tried to find out where the rattle was coming from
    It turned out it is the two latches on the rail that hold the trunck cover
    I squeezed two small pieces of soft plastic behind the latches and the rattle disapeared. You can use cloth or paper and it will do the job

    I am having this exact issue with my 2006 RX330 and it is driving me crazy. What exactly do you mean by the two latches on the rail that hold the trunk cover?
  • Hello Lakeitup
    Sorry for the delay ,
    The two latches are in the back of the car where you slide in the tonneau cover
    (the cover that you put in the trunck to hide your stuff inside)
    What I did is insert (squeeze) a thick carton in the space behind the latch so that the latch will not move anymore.
    The ratlle disapeared. It used to be very annoying when driving over a bumpy or rugged asphalt street

    I lalso found out there is a TSB for this.
    let me know if you are able to fix it
    Or I can send you a picture
    I dont know if PM is available on this forum

    On my RX 330, assuming you are not using the tonneau cover, I found that if you push the latch buttons to the position towards the front of the car the rattle goes away. Good luck!
