Lexus RX 330 Maintenance and Repair



  • Please don't put words in my mouth that I didn't write. The quote in your message was written by "lovingmylexus" not me. I responded to the very same message you cited above with my thoughts on the ECT mode.


    I don't have a problem driving on ice and snow (as long as I leave the ECT mode off).


    As for your comment on snow tires, my husband develops tire tread for a living so I am pretty confident that I have the correct tires on my vehicle.

    My apologies.


    Your names are very similar and easy to get confused.


    lovingmylexus....are you reading this? I hope so, because I'm not repeating myself.

    Snow conditions, wet, dry, heavy, light, deep/shallow, and drifting/blowing are the main determinants on how your SUV performs in snow.

    Starting and stopping difficulties have most to do with characteristics of the snow you're in, and a lot less to do with the make or model of SUV you're in.

    Four wheel drive systems, regardless of the technology your SUV is equipped with or the tires you have, won't help you much if snow conditions exceed their capabilities. I discussed this in detail earlier.

    Assuredly, FWD's are more effective than conventional 2WD in certain snow conditions, but don't get upset if you push the limits and get stuck somewhere.

    ABS and Skid Control Systems are also affected in much the same way.

    Braking distances in certain snow conditions aren't any better than conventional braking systems, and in some cases distances may even be greater, as Wwest has stated.

    The main value in these systems is the ability to control *direction* in a skid, not control or lessen distance.

    The same goes for so called "Snow Tires".

    Tread designs can improve traction and reduce skidding or aquaplaning somewhat, but not by large increments---and not at all if slippery conditions in snow exceed their capabilities.


    Rule of thumb--Don't expect miracles.

    It pays to anticipate the worst case scenario in snow.

  • fortunately total brake failure happened at low speed in post office driveway which has setback from main road, in order to miss hitting two pedestrians, i took right sharp nosedive over parking lot curb and angled a gravity stop on the grass of the setback, Worse however when i called the Lexus website customer support office, and told them my problem had been identified by dealer as the "brake booster assembly", they replied that, yes there have been problems, but "lexus policy" on this is to replace it after it fails; SO it seems lexus knows of the defect, which can easily be lethal, and instead of proactively protecting its customers, is reactively letting it happen and then fixing the part, sounds like DEFECTIVE BRAKES AND DEFECTIVE LEXUS THINKING

    Mildly curious as to why you didn't go to plan "B", namely use of the emergency brakes? That's one of the main reasons they're there.

    Also, sounds like your failure was a fluke--a defective booster is relatively rare. Catastrophic failure of your entire braking system is also highly unusual. Why?? Because there is a secondary backup in contemporary brake systems. If a booster fails you still have braking capability, but it isn't power assisted--sort of like the old days when power brakes weren't standard and you had to press hard on the brake pedal for brakes to engage properly. I don't think your secondary system would have failed too.

    Also unusual is the lack of feedback you would/should be entitled to under those circumstances. Lexus is one of the more customer focussed automakers in the world, and for you not to get any explanation is not a typical Lexus scenario. I wouldn't give up trying if it were me.

    You forget that were the antilock valves open no brake pressure could be applied anywhere. Rare occurance but then so was that cargo door departing from the 747.
  • hi, for sure there was no back up brake operating, my first reaction worked, but the emergency sounds right also, just went with my reaction at the moment, Lexus advertsies its customer focus, i have not experienced it, just get runaround, i think you are wrong about it being a fluke, and i have good reasons for saying that, if you know how to get Lexus to talk reasonably and acurately about this, i would love to get the phone number or email of that person, most of their contacts on web page are about buying a car and hyping their customer focus, hard to find anyone who performs on the customer side

    Wwest said: "You forget that were the antilock valves open no brake pressure could be applied anywhere. Rare occurance but then so was that cargo door departing from the 747."


    I doubt the antilock valves had anything to do with it, but nice try.!!


    For Taylor:..

    I get the distinct impression you wouldn't be satisfied with any consultation or explanation, but you could try the Lexus Customer Service phone no., or e-mail them at their web site. Good luck.

    Some advice: Venting your spleen at, or tearing strips off someone won't work very well.
  • wwestwwest Posts: 10,706
    unlike the 747 door, you don't think the wiring insulation could have frayed resulting in 12 volts being inadvertently applied to the brake pressure release solenoid valves.....


    One seems just as farfetched as the other to me.
  • wwestwwest Posts: 10,706
    think of another explanation for why two completely independent, totally isolated(***), brake systems could fail simultaneously but intermittently.


    *** except for the commonality of the anti-lock pressure relief valves.......


    Anybody know how EBD, electronic brake pressure distribution, works? Does it use the same anti-lock pressure relief valves?
  • pilot130pilot130 Posts: 319
    Wwest, keep up the good work. If nothing else, it's entertaining!!

    In the meantime, I'm getting the baggage door on my a/c checked out!!


    Think about this. Would someone with no brakes drive in for service, or have the vehicle towed?
  • wwestwwest Posts: 10,706
    slowly and cautiously but with my hand firmly on the e-brake.


    And you didn't answer my question.....


    What would be your alternative suggestion for the simultaneous failure of two fully independent brake systems?
  • pilot130pilot130 Posts: 319
    Sorry Wwest, it's foolish to even attempt to address your hypothetical situation which carries odds roughly equivalent to one person winning the same lottery five times in a row.

    Regarding the "tow or not to tow" scenario, that wasn't intended as a question--just something you might want to think about.

    Meanwhile,the baggage door story...........!
  • wwestwwest Posts: 10,706
    So, if your engine quits in the 210 and you go through the standard checklist and can't get it restarted I take it you would quit right there and not explore any hypothetical theories to help save your skin.


    I never, NEVER, want to fly with anyone of that mindset as PIC.


    Oh, and given the relative simplicity of even today's fairly complex automotive brake systems I would think comparing a hypothetical guess to even one lottery win would be extremely farfected.
  • pilot130pilot130 Posts: 319
    I don't see that rhetorical questions about aircraft have anything to do with SUV braking (or lack of), but I'll respond one last time, mainly because I'm a sucker for airplane questions.

    Engine failure can occur unexpectedly, but a responsible and competent PIC would have anticipated that contingency (among others),and would have rehearsed all relevant emergency procedures beforehand--quite frequently--and committed them to memory--plus have the POH very close at hand at all times..

    If not, he/she shouldn't be operating an aircraft.

    When failure occurs, immediately establish best rate of glide, go thru the complete engine failure checklist, try restarts as directed.

    It helps if PIC has these procedures memorized and practiced frequently, but it's better to follow the POH.

    Don't forget, a pressurized 210 is a complex aircraft, and checklists aren't your basic one liners.

    At this point the PIC is a very busy boy.

    If restart procedures not effective, determine the best site for emergency landing and set up for it accordingly.

    Broadcast aircraft ident,intentions,location, souls on board,on enroute and emergency frequencies; dial up emergency "Squawk" on expdr.

    Maintain proper airspeeds at all times, ie best glide rate, but adjusting aircraft attitude accordingly to ensure arrival at selected site at correct approach and landing speeds.

    Still a very busy boy--especially if passengers aboard.

    Please note there isn't much time to explore or ponder any hypothethical theories during all this.

    Land at site chosen at as safely and at slow a speed as possible---again, there's another (emergency landing) check list to go through before doing so--or might you have forgotten?


    Wwest, if you believe it's "right" to condemn PIC's who don't follow tried and true practices and wastes valuable time exploring theories in an engine failure,then so be it. I think you've been watching too much TV.

    Honestly, I'm glad I don't fly with you.


    As regard engine failures in a 210--it happened to me once (it resulted in a fuel system AD for all 210's).

    I landed quite safely in a farm field with no damage to pilot, passengers, or aircraft. I followed emergency procedures to the letter--thanks to Flight Training experience. I suggest you take their courses. They definitely don't advocate theorizing in emergency situations.

    Has anybody else reached 25K miles with their RX330? How much tread is remaining on your tires? Our RX came equipped with the Goodyear Eagle RSA 18" tires. The tread is gone! We'll be replacing them with the Michelin MXV4's before the end of this month.


    Regarding the previous discussion on snow traction, or lack thereof, I have seen multiple consumer reviews on these OEM Goodyear tires. Basically, everyone was faulting these Goodyear tires for poor traction in rain and snow. Doesn't surprise me too much. Why? These tires are classified as all-season PERFORMANCE tires. They have a "V" speed rating. This isn't exactly the type of tire you want to use in poor weather conditions.


    On the other hand, the Michelin version of this 18" tire is an all-season TOURING tire. The reviews I've seen seem to paint a more reasonable picture for poor-weather traction.


    I decided to buy the Michelins to replace my Goodyears mainly because they have a much higher treadwear rating. (I don't recall exactly, but I think it is "440" versus "260".) I also hope they provide a little better traction when we head to the mountains.


    I wish we had attempted to find an RX with the standard 17" wheels and tires. As of last week, there are still only two tires generally available for the 18" RX330 rims (tire size 235/55R18): the OEM Goodyear Eagle RSA and the OEM Michelin MXV4. Both run close to $200/tire. has reasonable prices for the Michelins, but you still need to factor shipping and mounting.

    I haven't had any luck in getting rid of the clunk or popping sound that is coming from the rear and unfortunately, it is getting worse. The popping sounds seems to be more pronounced when the outside temperature is above 60 degrees. The clunk seems to be coming from the hatch and only God knows where the popping sound is coming from.
