Lexus RX 350 Servicing question.



  • I could have driven 12,000 miles in 6 months... is that OK?

    5,000-Mile Or 6-Month Intervals
    Use 5,000-mile or 6-month intervals if you primarily drive your Lexus under any of the following conditions:
    - Driving on unpaved or dusty roads
    - Towing a trailer or using a camper or cartop carrier
    - Repeated trips of less than five miles in temperatures below freezing

    6-Month Intervals
    Use 6-month intervals if you primarily drive your Lexus under conditions less strenuous than those listed above.

    Lexus recommends replacement of the oil plug gasket whenever changing the oil. Don't know if an aftermarket replacement is available but OEMs can be sourced from Toyota dealers.

    Does maintenance come with new lexus purchase?

    I'm more familiar with BMWs and maintenance is included for first 4yrs/50,000. I thought it was included with a Lexus purchase as well, but from what I'm gathering from this forum it isn't. Someone mentioned they pre-paid for maintenance... anyone recommend what a good price is and for how long are the contracts?

    Only 5K service was gratis on my 2007 RX350, presume it is still the same. My 99 RX300 included both 5K and 10K free service as I recall. I generally go to a Toyota dealer for routine maintenance, about half the price of the Lexus store but no gourmet breakfast, free loaner or quick and dirty car wash. Same parts and level of competence, no problem whatever unless you have warranty issues; which are few.

    I've canged the air filter on other cars but I can't find its location on a 2008 RX350. Can anyone direct me please?
  • I see this has gone unanswered for more than 7 months - sorry, just saw it today.
    The air filter housing is located next to the battery, kind of between the brake fluid reservior and the big engine cover. Just went to change mine (for the first time) today - found absolutely nothing in the owner's manual. It's a little bit of a pain to get the filter out - need to loosen a couple of bolts, and remove a sensor connector, and then you have to wiggle the top cover (measures about 12" x 6" x 6") to gain access to the filter element. Then you have just a little bit of room to get the filter element out.
    Putting in a new element and putting it all back together is a little bit of a pain too.
    Been working on my own cars for 35 years - this is the most "inconvenient" air filter I've come across. Not impossibe though - it helps to cuss a couple of times.
  • Thanks very much for the helpful description. I watched my oil change guy remove it a few months ago and was amazed how complicated it is compared to most cars. Appreciate the response.

    I have done the oil change on my 07 RX350 for quite a few times. However, everytime when removing the oil filter housing, I had problems to lose the underneath screw, so it ended up that I need to remove the housing completely before draining out oil left in it, and no way to put the new plastic tube, etc.

    Anybody has the similar problems or know solutions for this?

    Hey Flowman,
    I was happy to read someone else has been through this.
    I am just going through this with my 2008 RX 350 now.

    Never ran into one I couldn't figure out !

    Looks simple. but......

    Bolts dont seem to loosen at all. Is there a trick to them? Do they come right out ?

    Looks like lift end closest to drivers side first after bolt issue.

    Is there a safe place to put a small screwdriver to pry open the lid?

    Please and thank you. :confuse:

    I'm going from memory here.......
    I'm pretty sure the bolts were captive - they don't come all the way out. No special trick to loosening them, but they might need a little snap to get them to break free.
    You are right about lifting the right (driver's) side first, then the left side has a tab that fits into a groove. I did not need to use anything to pry the cover open, and I would try to discourage that unless there is no other choice.
    The whole thing is not especially complicated, but there is not very much room to get the filter element out.
    I took some photos in response to ac2000's request back in January, but I couldn't figure out how to post them. They would have shown that it's not all that complicated. Just need to be really careful about disconnecting the sensor. Good Luck!
  • Hi. Had to change oil today and mechanic couldn't unscrew the oil filter housing. He is afraid to break it. It is supposed to be just handtighted but I guess at the last place I went to, they didn't know what they were doing. Any advice?
  • pschiffepschiffe Posts: 373
    This won't help and no disrespect intended, but avoid oil change joints. Use only genuine Lexus or Toyota parts and service. I usually have my RX350 oil changes done at a Toyota facility, same parts and level of competence at about half the price of Lexus. No quick and dirty car wash or gourmet breakfast but I can live without those. My 2¢.

    on the bottom left side of the MSRP sticker of my 2010 RX are several boxes with text. One of the sentences in one of these boxes states "complementary 1st and 2nd scheduled maintenance services"

    Hi all!
    I certainly think that it is wise to avoid those fast oil change places. Many of them have been charged with fraud after investigations revealed some service work was charged for but never done on many vehicles. They try to sell you everything from filters to tranny flush, to differential fluid changes. I would recommend either a Lexus or Toyota dealer for all your service. Oh Yes, I believe that in your warranty or owners manuals there are coupons for one or two free oil and filter services.
    Check with your dealer about these.

    Yes, that is if you can find a Toyota or Lexus dealer which will perform tranny service, regardless of oil changes and/or high-profit service "packages". It seems to be a rarity. Apparently, they usually prefer to "flush", or replace the transmission as a component.

    If you can make an appointment and wait while they drain and drop the pan, a good tranny shop will show you any sludge accumulated on the pan/magnet and any debris in the filter or screen. Type IV fluid usually has to be ordered ahead, they usually use Dex/Merc.

    Or maybe I'm too picky.
  • Hi, I was wandering if any of you are earing some cracking noise from your RX350. I've own mine since almost two years now and it's getting worst. I have some noise coming from the dash. I had to remove the vinyl trunk cover, "SORRY don't know the english word for that one" it was making such noise.

    Anybody ever heard of fuel injector service on an RX350? I often take my RX350 to a Toyota shop for oil changes and last time the service adviser stated that they recommend that this be done every 25,000 miles @ $99.95. They claim it is necessary due to the high sulfur content of fuel in this area (Buffalo-Niagara Falls region). No mention of this in the owner manual or by my Lexus dealer nor was this ever done on my previous RX300. I suspect there is no necessity for this and it frankly damaged my opinion of an otherwise very satisfactory Toyota shop. I declined the service, any comments? TIA

    Pete :(
  • Just before I got my 2010 RX, my lexus dealership on an oil change visit recommended a "fuel induction" service on my '07 RX. It was to clean up any carbon build up. Maybe this is what they meant?? Needless to say, I declined to have that done.
