Our second row seats also squeaked, but not all the time.

I finally correlated it to the position of the fold-down armrest. I would push the arm rest up at the car wash ... one less thing for them to lean on ... and the seat would start squeaking. Eventually, we would fold down the arm rest for rear seat passengers ... and the squeaking would stop ... until it went through the car wash again!

Needless to say, the arm rest is down at all times now, except at the car wash.

P.S. I suspect a leather treatment would solve the problem as well, but my solution was easier ... and free.

My 2012 with less than 2500 miles does the quoted above ... at 1st service the dealer checked it and said everything normal .. it's kind of normal for truck to do .. even though not this soon .. will keep any eye on it and see if it gets worse.

Do you mean the rattling noise .. if thats the one I suspect it coming from the rear right passenger seat belt .. mine does the same I will get it check on next due service.

My 2011 does have the same noise as SaniDel stated. It is the 2nd row armrest. When stored in its uptight position.....tick.tick.tick.....when down nothing.

I sympathize with your predicament as I have been there. We've owned 10 'Lexi' and a few of them have squeaked enough to require intervention by the dealership. Some of our Lexi never squeaked ... our LS 430 was as quiet as a tomb.

However, some of our LX and in particular our GX are also quiet. May I suggest that you politely 'decline' the argument that "all trucks squeak"? If our early-production (November 2009) GX460 with over 30 thousand miles doesn't squeak, then Lexus can build trucks that don't squeak. The challenge is for your dealership to find and fix whatever is squeaking in your truck.

If your dealership is as good as ours, they will examine your GX until they have heard, isolated and solved the source of the squeak. If necessary, you should take them for a ride ... no pun intended ... until everyone in the vehicle hears and agrees there is a squeak. If they deny the squeak ... or worse, refuse the ride ... you'll need a new dealer!

My 2013 GX makes this noise when I step on the gas padel when the speed is 70 mph or higher. It is not very loud but noticeable, even with the radio on. I noticed this these past two days on highway. There is no such sound during local drive or speed below 70. It sounds like it came from the engine compartment, but I am not 100% sure. Is this normal? Could it be from the wheels or chassis? My truck only got 1800 miles after 2 months driving.

SaniDel

You're already driving at 70 MPH ... and accelerating, right? Are you really surprised to hear more engine noise in that situation? That's the "sound of power" ... you have to temporarily increase engine output to accelerate, but it should decrease when you are at a higher constant speed ... and decrease further as you slow.

Here's an experiment. Use your cruise control so the GX tries to hold a constant speed regardless of load and take a road trip with plenty of upgrades and downgrades. That should be easy in Pennsylvania, especially as you head west. Turn off the radio and listen to your engine ... it should be loudest going uphill, less on level ground and even less going downhill.

If you have the transmission in 'D' it will try to keep in top (6th) gear, but it will unlock the torque converter and eventually downshift if it can't maintain speed. Driving the Pennsylvania Turnpike on cruise control will demonstrate this.

What octane are you burning? Could it be you are hearing the engine nocking on too low an octane? We've had many discussions about gasoline, but if you burn premium and especially from a "Top Tier" retailer you shouldn't hear knocking.

Is this noise new? Take it to the Stealer, let them take a look. If they say it's normal, ask for a ride in a demo model.

Don't know if you have cross bars on the roof? My QX4 had whistle noise on the highway and it was from
the bars on the roof. I don't have cross bars on my GX 460 and I don't have any noise at any speed.

Eppieguy

Good Point, My Tahoe did the same until I took them off, my friends Pacifica does it too, drive me nuts.

Teddyofind

The noise is there when I step on the gas panel and when speed is above 70mph, no mAtter I keep constant speed or accelerate. I tried this morning and it is suprising that when the speed is above 80, the noise is gone or nearly unnoticeable.

Yes, I mostly filled up with Sunoco 93 octane gas. So it is safe to say it is not the gas that is causing it. I will try the cruise control method sometime when I got a chance.

Teddyofind

No I don't have crossbar on the roof.

Well, I replaced the AT tires with some nice quiet Michelin Latitudes.....MUCH quieter ride but the drive train "whine" is still there. It's been about 20K since my prior post and the noise has not changed at all, and is very intermittent. Sometimes its more pronounced, other times you can't even tell. But, its still there and I'm happy to report no change. Based on that, I would venture to say this is normal. I will be putting it to the test at the end of the month with a trip up north (1000 miles) and will be towing a heavy uhaul trailer. If the noise doesn't change or is unaffected after the trip, I will definitely not be concerned about it in the future.

Now I don't have any rear seat squeak, but I have developed a driver's seat "pop" while turning. Not sure what that's all about. If I turn sharp, it almost feels like the seat slight shifts and it makes a little clunk sound. If I change the position of the seat, it stops. Just so happens the clunk is right in the position where I need the seat to be comfortable. Anyone have this issue???
