GX550 Overtrail Vibration

What size tire did you put on?
285/70/18

Snug fitment up front. Barely rubbed the lower cover (w/ the three plastic push pins) behind the front passenger tire at full lock. Removed the cover from both sides. No rubbing anywhere now.

No lift? Any pictures? I keep hoping to see if those tires would work on the stock rims.

No lift.

I'll post pics over in the aftermarket wheel thread when I have time to upload some decent pics.

Somebody with a Nori has that size on Overtrail wheels. They fit fine and look awesome.

Went to my lexus dealer and test drove a premium and lux+. Premium didn’t have the adaptive suspension and it was the smoothest. Took the drive into old suburban neighborhoods with rough paved roads. The lux+ and my overtrail plus drove the same. Felt every bump. The premium smoothed the small bumps out. This leads me to believe its the adaptive suspension not working as well as the regular suspension on small bumps. Just my 2 cents
 
I have been speaking with 1-800-Lexus and they will reveal nothing about the vibration (my biggest concern), hood flutter and brake noise (annoyances) other than being polite and then saying I should work with my local dealer. I told them I would be happy if Lexus would state they are looking into it, but they keep going back to “individual experiences” and “work with your local dealer” which tells me they are trying to avoid a costly fix. Even my local dealer told me they are working on the brake problem. I asked Lexus what I should tell people when they ask about my new truck … I can’t recommend it at this point.

Frustrating... Been said before but this will surely be looked at down the raod as "first model yr." type issue. Would be very "untoyota like" not to fix. We may never completely understand the root cause if it doesn't reveal itself out in the real world. Should be picking mine up within the next two weeks and there's a definite drumroll playing in the back of my head. Not sure if I'll pass on it if it vibrates unless it really stands out.

This is probably a good first-hand description of 3 trucks that are as intended from factory. The ride is bumpy. Noticeably more so than my prior 470, or older 4Runners, for example.

I think what we're hearing about the supposed brake-related vibrations is a recognized flaw (or at least becoming one). Hood vibration is a design flaw, but not something that intermittently affects. It's universal. I think a lot of other accounts of a harsher than expected ride are just the way the truck behaves.

Anyone who thinks they're experiencing the vibration issue really should immediately go test drive another on the lot. That's the only way you'll know if you have an issue, and if you think you're experiencing the vibrations, take a tech and service advisor with you on both drives . . .

I get mine on Thursday, will take if for a test drive at the dealer before it heads home.

I have literally heard both of those exact same answers several times. Pohanka Lexus in Chantilly Va is by far the worst service experience I have ever been associated with. Honestly the only dealer service department ive dealt with, i usually work on my own stuff, and have never had these types of issues with a brand new vehicle before. Let alone, an $80k “luxury” vehicle. My case manager has a meeting set up for me with a Lexus engineer for 10/28. Anyone dealing with these issues should hit up their case manager and request a meeting. This person will be in the Northern Va are from 10/28-10/30 (Mon-Weds).

I'm up to just under 800 miles on my OT. The only noise complaint is from the roof rack. I'm extremely happy with everything else, so far. As far as driving another one at the dealer, you can't here. They don't have any that aren't spoken for.
 
Just picked up my OT+ yesterday and drove it 200 miles home. My thoughts:

Looks a tad bit smaller (4-runner ish) when I first grabbed it and not a huge fan of all the glossy black finishes (atomic silver with black roof), almost wish I went monocolor. Interior is definitely not as “refined” as Volvo but man it’s clean lines and incredible visibility, love the hood lines and flat dash- great tech too. Felt immediately like taking it on the trails(just need a bumber with winch).

Immediately went to service manager to ask about brake caliper issues, vibrations etc and he said no known issues. Took for test drive and salesman told me he thinks it is “bumpy at low speeds due to off road tires.” I didn’t notice that at all. My personal car is a v90 xcountry wagon and it’s extremely tight and rough suspension. My work trucks include, Tahoe, Durango, f250 and previously drove f150.

I think the salesman is used to selling lexus cars with road suspensions vs off-road body on frame etc, this truck drives supremely well. I did notice vibration on the back passenger seat at 75-80 but did not feel it reverberate through the steering wheel. I love the little bit of give the wheel has, found it extremely easy to drive for long distances. Notice hood flutter but non issue, seems normal for aluminum frame vehicles nowadays. Also notice rear bumper plate is flimsy- but don’t mind it because it’s modular and made to be easy to replace.

In normal mode, acceleration from stop is a bit delayed, annoying but seemed to get better with more driving?

Absolutely felt this truck glide over bumps on Vermont dirt roads that my xcountry wagon would feel violently, this GX just eased in and out of the ruts.

Off road trucks handle differently than lux SUVs. I am intrigued about the caliper issues and monitoring to see any changes. I’m thrilled with first impressions. Just for info I was totally all in on the grenadier until price woes and low trade in values from local grenadier dealer…

Meant to add, the cool box is a total waste of space 😂
 
Update on my vibration issues. I went to the dealer yesterday for the 5th time. Technician rode with me, with my brand new michelins that they provided, the ride is still vibrating like hell at 75 MPH+. We swapped out the wheels and tires and put on the wheels and tires from the Demo GX which is a Premium+. The truck definitely rode smoother with the Premium wheels and street tires, but the vibration was still there. Tech said he couldn't feel it as much (I still noticed it, but it was a little better). The tech asked if he could drive my car home, so he can spend some more time with it. I agreed, and took home my RX loaner for the 4th time.

My tech does not believe this is a brake issue. I feel like the brake parts are not available and so the dealers are trying to avoid this as a possible issue simply because they don't have the parts to fix it. I am going to let them keep my car for as long as they need it, and then if it can't be fixed, which it seems like it can't be until the entire brake parts are replaced, then I will go with plan B and trade it in, lemon law it, or discuss buyback with the dealer.

Unbelievable that this is a Lexus and we are going through this. Not sure if you guys are familiar, but if you're not, I would recommend researching what happened when Lexus had a recall with the very first LS 400. Then, after reading about all the hoops they jumped through to take care of those customers, compare that to what we are experiencing with these GX's. "The passionate pursuit of perfection" is long, long gone.

Mind blowing at this day and age with a company as capable as Toyota. Hang in there and keep in mind you’re helping other GX owners who are possibly dealing with the same issue by going through the BS. It will be resolved at some point.

My patience is growing really thin, I have decided to give it until the end of this month. October will be 5 months of ownership for me and if not resolved by 10/01 I will begin "next steps" but hopefully it does not come to that!

Good plan. Did you happen to print out and show your service person the "work order" sheet "sroberts" posted earlier in the thread? This shows updated part #'s she had replaced which was basically the entire brake caliper & rotor assy. Not sure yours can be attributed to the brakes but might be worth getting on the record with your service team.

Yes I did but the tech didn’t take it too seriously. I even spoke with S Roberts and they gave me the vin from their car and I supplied it to the tech along with the parts order, etc. He didn’t take it too seriously and I fear that’s because the parts simply aren’t available.
