Lexus GX 470 Maintenance and Repair

    my Navigators got me 12 in town

    alexmn76: I had a Navigator two cars ago and it's hiway driveability was far superior to my wife's GX. I've been very disappointed w/ the way the GX maintains road stability at high speeds, so if you're replacing your wife's Navigator and plan to do a significant amount of extended high speed hiway driving I cannot recommend the GX. It is clearly not the concensus on this thread that the GX is awkward at high speeds, but there are quite a few posters who share my experience

    I haven't been to the dealer yet to ask about the cruise control 'features' - I only have just over 3k miles on mine. It is quite annoying, and my husband does the same thing with shifting to 4th. Actually...he just keeps it in 4th the whole time in cruise. We live in Texas - so its kinda hard for us to tell when we're approaching a 'hill' - but the GX certainly KNOWS! Anyway...shifting to 4th helps the problem, but causes about 2-4mpg decrease in fuel efficiency. I've just learned to accept the 'feature', as its WAY better than the transmission problems I was having in the ES (see ES forum for more of THOSE horror stories!).

    All in all, I'm pretty happy with the GX though....

    I don't experience the vibration in the brake pedal, except when the ABS kicks in - which happened TWICE this week. When that happens, the brake pedal drops to the floor, and it feels like the brakes actually aren't working anymore! It freaked me out!! The first time it happened when I hit a large pothole while slightly braking as I approached a stop sign - yikes! The second time, the next day, was actually because I slammed on the brakes for a valid reason. The tires skidded momentarily, then the brake pedal dropped to the floor and vibrated slightly - and I came to a stop.

    As for the clunk - I do feel that at most stops. I think its actually just the car shifting out of gear. The first few times I actually thought I had been slightly rear-ended. But now...I've gotten used to it. Doesn't seem to be any kind of safety issue, b/c the car reacts quickly and smoothly when the gas pedal is then depressed. So, I'm not too concerned with it.

    Not sure what your problems were with the LX, but I did have horror story problems with my ES. So...I know your uneasy feeling of concern - the 'did I just get into ANOTHER problem Lexus?' feeling. Anyway...all in all, I am quite pleased with the GX.

    Got it, blov, thank you. Before I buy, I'll investigate this issue thoroughly. Frankly, I loved my Navigators, and long for another one. They were great trucks.

    Good solution ... never crossed my mind! At today's gas prices I wouldn't want to regularly give up on 2 - 4 mpg but on the drive between Tucson and San Diego it makes sense to drop back to 4th for the western 1/4 of the trip to get away from that annoying incessant downshifting of the cruise control.

    A Lexus is in no way in the same relm of a Lincoln Navigator. A Lincoln is a glorified Ford and Fords don't last very long as far as reliabaility goes! It seems me to me that some people are just beyond picky. I have a 2006 Lexus with 5k miles and if reported no problems or imperfections with the vehicle. My last vehcile was a 2004 Audi Allroad Quattro and again there is no comparison in the ride or the ameneties that Lexus offers to their customers. I know for a fact that Lincoln with not give out a loaner car for an oil change but Lexus will with no exceptions to it's customers. I have taken my Lexus GX 470 offroading as well and have found the offoroading in the vehcicle very compliant. Try taking you Lincoln Navi in dirt, it would probably break apart into pieces on the first bit of dirt it touches.

    Don't even start with the "Glorified Ford" stuff again. The GX470 is a glorified 4-Runner, the LX470 is a glorified Land Cruiser, the Rav-4 is actually a Corolla under there, the ES-330 is a glorified Camry, and on and on. I own a Lexus, I know how good they are! But Ford is the truck king, and Ford trucks, whether they be Lincoln or Ford, are darn good too. Whether or not you like them.
    Secondly, Lincoln has NOT ONCE failed to give me a loaner for an oil change, or any other service I've had, for the past 15 years! Finally, if you bother to check my carspace, you'll see my 03 Navigator (may it rest in peace in Phoenix somewhere) in Death Valley, on the Race Track road, which is a 30 mile one way jeep trail only, and it not only came back without incident, it had just as many rattles as when we started - 0 -. Your comments are unnecessary, your facts are in error, and if you have not had one, unresponsive. So let's just move on please, to helping people with their problems here constructively.

    First of all, as already posted the GX is a dressed up and oversized Toyota 4Runner. Second, next time you're in an airport count the number of Lincoln limo's v. the Caddy limo's (and Ford cabs, for that matter) Lincolns are far better assembled for endurance than GM. I will not deny for a moment that Lexus dresses up a vehicle better than just about anyone but that doesn't make it a great hiway vehicle. It's road manners, not overall vehicle quality and finish, with which I have my beef. Bart
  • Just bought a new GX 470, and my salesperson, who seems to be pretty knowlegable about the car, told me that LEXUS needed to fill the tires with air in order to "register" the tire monitors properly.

    I was surprised -- "You mean -- if a tire is low -- I need to bring it in to Lexus Service?!"

    "Yes. Otherwise, they won't report accurately."

    After reading the GX 470 Owner's Manual, it seem like Lexus absolutely didn’t care if you fill your tires yourself, and in fact, recommend you check and maintain tire pressure. No warning about Lexus Service needing to "register" or adjust each monitor.

    I understand the need to "register" new tires with different batches of monitors. That makes sense.

    Has anyone EVER heard this before? Is there anything about this issue (like a TSIB) from Lexus? Where could I refer this salesperson if she is misinformed?

    Our GX is an '04 and from what I can gather from the salespeople and the manual the tire monitors only signal a "low" inflation "too late light". I don't get their reasoning. I'd rather have NO monitors and rely on my old hand-held guage than have a semi-reliable monitoring system. My daily ride is an Infiniti M35 ... it monitors all four tires but not accurately enough for me to feel totally comfortable with inflation. I still check them every couple of weeks. Bart :(

    I had the dealer search for a tsb fix for the brake clunk, and they found it and ordered the parts. I go in tomorrow for the fix. Hope it works. :sick:
  • cdfwifecdfwife Posts: 37
    The Lexus dealer fixed the brake clunk. I haven't had a problem since. They also waxed the car and clayed it, and it feels and looks awesome.

    How dissapointed I am. I use to have the LX470 for 5 years I choose to go to the GX because it was something new but same. I have only have had the GX for 1 month and it has gone in for service 4 times. The GX starts to vibrate and shake once it hit 54 mph. which is crazy. They say it is because of the tire and wheels I brought the car with. They have changed the wheels tires and bolts and it is still doing the same. I was told if I put the original wheels and tires the vibration will go away.. However, reading that I am not the only one with this problem I dont think it will work. I just cant believe Lexus would sell a brand new car with wheels that don't sit right on the car. Especially when one of the reasons I bought the car was because it looked pretty with the wheels. What can
    i do?
  • BCardenas,

    What year is your GX? How many miles on it? What were the original tires and what do you have now?
  • blov8rblov8r Posts: 567
    If that vibration remains with new tires and wheels, and yet another set of tires and wheels, you may have an unfixable problem and a legit claim under your state's lemon laws ... unless you've leased in which event lemon laws have (at least in some states) been judged not applicable to leases. I recently read with some skepticism that someone had a similar vibration and the dealer/service department said it would settle down and stop in ~ 500 miles. I don't buy into that explanation. Having personally owned MANY new cars of all descriptions, having rented heaven knows how many more, and not knowing a single person who has had such a problem I've got to believe you have a problem car. Insist on having the wheels and tires changed AGAIN and don't cave in to any pressure from them. If you don't get satisfaction from your dealer, go to the Lexus regional office. :mad:
  • This is utter nonsense. You yourself can put air into any tire that needs it on any Lexus vehicle. Where do some of these sales droids come from?
  • In this case, my salesperson insisted that this is how they were trained by their "Lexus Trainer". I've spoken with Lexus Corporate about the issue, to try and make sure they get someone back out to the dealership to "retrain" the salespeople.
  • I have an 04 GX470. My wife drives it 95% of the time. Beginning around 12,000 miles brakes started to pulse under normal braking. Feels like the rotors are warped. It got progressively worse and now has 20,000 miles. We took it to the dealer and they are stating that it is not a covered warranty item as the vehicle is over one year old. I've had less expensive (lesser quality) vehicles with more miles, driven much harder and without any brake problems. Has anyone had this problem?? Any suggestions on how to get this resolved under warranty?? I'm not getting any satisfaction with the local dealership.

    Do any of you that have handling problems have the KDSS package. I am intereted in buying a 2006 GX 470 but on my test drive I did notice more sway then I was comfortable with. I understand the KDSS package improves handling on the highway. I did like the quick acceleration and the quietness of the ride----did not notice any clunking (but then the darn saleman is chattering away. Also, does anybody run regular gas in the 2006's?

  • blov8rblov8r Posts: 567
    Sorry to seem dense, but what's the KDSS package? I guess (from context) it's a suspension package. You did indeed notice the sway that I and others here have noticed and complained about.

    Insofar as regular gas is concerned, I NEVER run anything less than medium octane (eg, 89 v. 87) and more likely use premium particularly in a car/truck I plan to keep for years ... as is the case with my wife's GX as she typically keeps her ride for 10 years. Bart
