Long-time RX 450h owner here - beginning to approach a plan to sell the RX in late summer/early fall '26 and just trying to do some research on RX-alternatives.

I've read lots about the GX460, but I have two sticking points which are holding me back a bit.
1) I really do NOT like the 4R, and see lots of reports that the GX is just a more luxury version of the 4R. Specifically, there are two issues I have with the 4R:
a) I HATE the entry elevation of the 4R (every one I've ever gotten into - '98, '06. '08. and even the newer '23-24 year models). It's too low to make using the step bar a practical need (like the way I HAD to use the step bar to get into my '02 F250 crew cab), but too high to easily step into (like the RX), and
b) I feel sort of cramped in the 4R in terms of physical seating width - the cabin just feels tight to me.
2) My budget is going to be around ~$30k, and my brain hurts to think of having to get a vehicle that is roughly 8 years old with around 100K miles for that amount of money.

So, perhaps the GX is not just a reasonable option for me, but I wanted to check in here to get some input/insights from actual GX owners (instead of journalists) to either clarify, dispel, or validate my suspicions.

What say you?

 

Those things are all pretty user specific.

I think you will find your suspicions to be correct though.

On the steps....I find you are correct, BUT...they are too in the way to step over so you kind of have to use them. I am the type to never let my butt slide off a bolster though, so steps it is! My old lifted FJ Cruiser was the proper amount of 'step use' to 'seat height ratio' though (close to an F250 honestly) - with a GX you are NOT going to get your F250 feel back. The auto-retracting steering wheel and seat does help a little on entry and exit.

You should go drive one.

 

... you would be going from an integrated body (sedan based) vehicle to body-on-frame (truck based) vehicle ... apples and oranges. The GX460 is essentially a Toyota 4-Runner on steroids ... V8 vs. V6 ... Full-Time 4-Wheel Drive vs. Part-Time 4-Wheel Drive (unless the 4-Runner is the Limited version) ... Luxury Interior with more Soundproofing ... and KDSS (unless the 4-Runner is the Limited version) ... blah ... blah ...

Again ... RX vs. GX is not a "step-up" SUV in the Lexus model line ... unless you really want a truck-based vehicle ... that also has great off-road capability as a bonus. Even with the GX460 Luxury AVS Shocks the GX will never ever ride like a sedan-based vehicle.

 

'I really do NOT like the 4R...'
Of course give GX a test drive, but prob start to look elsewhere. Relative to every other automobile out there, the GX interior is most like the 4R, not the same, but most like. Also 1UR-FE engine tends to have a bunch of maintenance issues around year 10/100Kish (radiator, coolant valley, time chain leak etc.). Not catastrophic, nor does everyone have these issues, but not that unlikely nor are the costs trivial.

 

You have not stated any reasons why you WOULD want a GX460, and there are many, but "it's the next level up the Lexus ladder" is not one of them.

They are heavier, probably slower, use more fuel in all situations, harder to park...if you don't have a good reason for wanting a body on frame, full time AWD, V8, fuel disappearing machine, then probably don't.

If you're looking to tow something, or deal with inclement weather conditions, on unpaved roads, in comfort and confidence, there are few better vehicles.

If you don't like the step height, you can install lift springs to your preferences, that's a thing that is easily possible as it's "essentially a 4Runner", and aftermarket suspension support is strong.

But go drive one 1st, and in the city you put it in "4", or it's going to feel lazy.

 

Personally an RX450h 4th gen would be a perfect fit with your requirements if staying in the Lexus lineup or a slightly used or new Highlander (hybrids might be out of range). Way more practical, way more modern, as or more reliable tested powertrain, and entry is sliding in and out (delete any of the side steps those were terrible).

The GX does not hide its utilitarian roots that well, has less kit, less room yet the same length as the CUVs.

 

Despite the J150 GX and N280 4Runner sharing the same base F2 platform architecture, the GX feels, behaves and performs like a 15/16th scale J200 Land Cruiser rather than a 4Runner.

Subjectively speaking, getting out of a 4Runner into a GX it's hard to believe they share anything except the wheelbase IMO, not even steering feel is similar (again, GX feels like a J200 Land Cruiser, not a 4Runner/Tacoma).

If you don't need the towing or off-road capability of the GX and a CUV meets your current needs then the GX probably isn't ideal for you.
The GX is a [refined] truck through and through, with all of the benefits and drawbacks that entails.

 

First go and test drive a GX460 to see if it is for you, as already stated it is truck based (body on frame) and not a unicode like the RX so the driving dynamics, weight etc cannot be compared at all.

The GX460 is a Land Cruise Prado in a suit/tuxedo, dressed up to look nice, but driveline, suspension and interior space is identical. but in LC Prado you can get a diesel, GX in US is only the V8.

I've had 4R as rental and it does not drive similar at all to the GX, also the interior volume is different, the GX have more height inside, making the feel different.

GX has the barn door and window that tilt up, 4R have the standard tail gate but a window that slides down like a normal door window (I woudl love that option in GX) but as GX is a LC Prado when the tailgate can be optioned to hold the spare tire and extra fuel tank, the barn door design does not allow for that.

I just had 2 different rental cars this weekend and week, a Nissan Rouge and Chrysler minivan, both drove nice and no issues, but both had rattles and were noisy inside, today back in the GX, and it is too smooth compared and no rattles and less road and wind noise. our GX is a Sep 21 model with 72k miles (purchased new). but rentals had less than 19k

Again go a drive a few to see how you like it.

For us we will not get rid of it, and I'm also looking for a reasonable LC200 to add, as the understated design and capabilities are amazing.

 

Wow... your details and comments drive right to the heart of real-world issues that I've been wanting to hear about. I really appreciate your direct and specific answers. Allow me just a few moments to add some clarity to a few questions you've posed back to me for additional context around my search criteria. First, though, the GX is the only truck-like option I'm considering... all others are mid-size SUV's, and I've even posted a parallel thread in the 3rd Gen subforum (where I have typically participated for obvious reasons) >> https://www.clublexus.com/forums/rx-...om-the-rx.html

OK, not in any particular order of priority...
- TRUCK things: I owned my'02 F250 for almost 20 years, purchased with 112k miles and sold with 365k miles (CC, 7.3 Powerstroke Diesel, 2WD). I never needed the towing capacity for this beast, and only purchased it because it was first and foremost a truck, and second it had a legendary diesel which promised very long-term reliability. It lived up to all the hype and was, in different ways, as good as the Lexus has been in terms of comfort and reliability. I sold it only because we felt like we could survive being a single-vehicle couple since I now work 100% remote from home and over a two-year period only averaged 65-75 miles per month on it. For the few times I need a truck bed in a year's time frame, I can rent either a pickup or small box truck for much less than the annual insurance costs on the F250. That said, I will occasionally need a volume vehicle to haul lumber and landscaping supplies to support my hobby habits and home maintenance/upgrade tasks.
- Interior Roominess: I'm a broad-framed man at 6' and 200 lbs, and need elbow room to be comfortable on long drives. At the same time, my wife is very petite (only on the outside, though) at 5'1" and 100 lbs. My wife also spent over 20 years driving either a Suburban or an Excursion diesel, but since all six of our children are on their own, we just do not need and cannot justify the use of those types of behemoths (even though I would dearly love to still be driving one of them). We have a habit of visiting lots and lots of antique stores with occasional antique furniture purchases as far as 5-7 hours away from home.
- To be clear, I'm not trying to make an apples-to-apples comparison between the GX and RX family lines. My comparisons are only contextual in nature and not absolute. I will freely admit to a growing interest (and enjoyment) of luxury creature comforts while both admiring and wanting to have utilitarian characteristics in the do-it-all-for-every-event single vehicle. I know that a single vehicle cannot do it all, but I will push myself to come as close as possible, and I remain well aware that my prevailing need is 95% DD with several long road trips annually - pushing the balance towards the creature comforts without completely losing utilitarian features.
- Having stated the above, my interest in the GX should be more clear - a strong desire for luxury interior without completely losing utilitarian capabilities. Where we live (Upstate SC) and travel (both to the coastal beaches and across the Appalachians into central TN), inclement weather can be a limiting travel issue. Again, it is not an issue of "needing" the towing or off-road capabilities. It's more based on the context of knowing what a heavy truck/truck-like vehicle offers in terms of both road stability and point-of-impact.
- Installing an aftermarket lift is not an option, though, as I must keep the vehicle very entry-friendly for my "not tall" wife. I can probably live with that issue the same way I continue to live with driving an "egg" with a CVT.
- The barn door is not a problem. Our Excursion had the double barn doors with a lift window, and in our minds, it just "one more way to do it".

So, with all you've shared with me, I will keep the GX on the list for now and drive one or two of them to settle the issue in my own mind. I'll also do a little more digging into the 1UR-FE engine issues to gain a more solid understanding of that potential $$ risk.

Thanks again for all the input.

 

I'm 6'3" 190 lbs.
The GX is better suited for tall people than the 4Runner is.

The GX's barn door removes the head smack reality of liftgates and the greater floor-to-roof height of the GX offers more head room.

The port injected UR engines are proven million mile capable V8s but are less forgiving of a poor maintenance regimen (specifically oil and coolant intervals) than the UZ engines they replaced.

The main UR issues (and this applies to all of them, including Land Cruiser, Tundra, LS460, etc.) is the coolant valley plate leak and timing cover leak.

Other potential issues are the cam tower leak and driver side primary timing chain tensioner.
There is the occasional high mileage head gasket issue, but I believe that strongly correlates with lax coolant maintenance and/or overheating due to low coolant levels (cracked radiator, valley plate leak).
Even the 2UZ pops head gaskets for the same reasons, and that's objectively one of the most reliable engines ever produced.

 

Pete, My wife (5'1" 100lbs) had a 450h and I(5'10" 170) have the GX460. She traded hers in for a Volvo XC60PHEV (she liked the looks). I still have my GX. I love it. I have no problem;em with access, though there are runners on the side, I don't use them for steps. I do, on occasion, need to move stuff (bags of leaves, lumber for small DIY projects, artwork for a friend). It works great for that. I also live in CO and this vehicle is excellent in very nasty conditions.

 

Maybe a lightly used Mazda CX-70? That seems like it is in the $30k range, enough size, without many years on it. If you get one, let me know how it is, maybe I will buy one

 

different use cases
for most id bet that the rx is a better fit to needs
yeah gx looks tougher, is tougher, but at a cost. worse mpg, rougher ride, tougher parking, entry/exit issues for some.
rx has independent rear, something i think is better for the majority.
4R is more squished vertically, less refined, not a very good gx comparison
gx barn door is very well suited for my needs. others not so much.
an rx with the 3.5 v6 with the options you need/want might be ideal

 

I traded in a 2023 4runner for a 2023 GX460 and my wife has a 2025 RX350.

Coming from a 4runner, the GX is an improvement in almost every way: smoother ride, better interior, much quieter inside, full time 4wd feels better, better turning radius and maneuverability, etc

Coming from an RX, you probably won't like the GX, especially as a daily driver. The RX drives much smoother on-road, gets better mpg (obviously), and has much more of a "car" driving feel, just with more interior space. I enjoy driving it more than either the 4runner or GX. Meanwhile the GX drives like a nice truck.

If I didn't need 4wd for occasional rough road jaunts, I'd just get an RX.

No matter what you do, test drive and inspect first.

 

OP yes it’s a good way of thinking about the GX as a luxury 4Runner. Its not exact but close enough - quieter, more luxurious interior, 3rd row, more flexible hvac control for passengers, etc.

I’m 5’9” and shorter legs and I do not use the step to get into the GX. It is a tall vehicle tho, so if you plan to load up a roof carrier, dyi cleaning and waxing the roof, etc. you’ll probably need a stool or short ladder. Haven't measured it but I’d bet the cargo area is higher up on the GX vs a 4Runner.

There are other shortcomings too - mpg is low, smaller gas tank means you’ll stop a gas stations more frequently, more of a truck ride vs your RX (which I like), etc. Go drive one and see for yourself.

Best way to see if any of this bothers you is to go test drive one.
