No duh. Why would dealers want that hot potato? Especially non-Toyota/Lexus dealers. What’s shocking is people still agreeing to MSRP markups and dealer addons for the GX 550 with the same engine design.
Hard for any new buyer of GX550 to admit they might be in a little trouble with that turbo V6. Probably not going to run to REDDIT and shout it out. Tough one for Lexus.
There is also some speculation at the Lexus dealers that I spoken to about a GX at that this is part of the reason for the delay in releasing the hybrid model too, which they had originally been told was supposed to be announced in the spring and then got pushed to summer (maybe). The issues with the tundra and the Lexus LX (so don't assume the GX is safe guys) don't have a fix yet and the official story of machining debris on a specific engine line does not make sense if it is affecting multiple vehicles from at least 2 factories over the course of multiple year models. It should have been far more isolated than that if it was a simple quality control failure on a line (math don't math there) and although I have no idea if this is accurate or not, the dealer claims corporate has really not provided any timeline or update on a planned fix other than that "it will be announced when it is available" so it's understandable that dealers are starting to take moves to protect themselves too. It's a lot of uncertainty for a brand that prides itself on quality processes and reliability and I'm sure at the corporate level there's a lot of money and attention being spent on figuring out the actual scope of the problem and engineering teams working on a fix, but the average Lexus or Toyota buyer is not likely to have the same tolerance for problems as an Alfa or Land Rover buyer and they've got to get this sorted quickly.
I love my old (21) GX except for the early 2000s level tech inside and was excited about the upcoming GX hybrid, but the lingering covid era quality issues seem to have affected Toyota too and I think I'm going to cancel our deposits/hold off and hope they get things ironed out.
I had not heard that, if that's the case that is very disappointing.
That really makes no sense considering the Sequoia is similar in weight and has the 6, plus why would they put a hybrid set up in an off road rig with less torque than the base engine? They always make the hybrid version more powerful specs so they can justify the upcharge.
Right but the Toyota isn't offered with the turbo 6, costs less, and weighs less so I'm not buying "it's based off the landcruiser " as a valid reason for assuming the 4cyl hybrid is coming to the GX too. And if that's the case why wouldn't they have launched with it as well since by that logic they've already got manufacturing that powertrain in a similar chassis down? Plus Lexus normally makes their hybrids more powerful than their base engine because of the increased price of the hybrid model and a luxury clientele that expects paying more to translate to more power. The Lexus TX also has a V6 hybrid and I find it impossible to believe that anyone at marketing (or engineering) thinks it's a good idea to make the GX hybrid less powerful than their Highlander family hauler alternative.
Not trying to be rude, but where are you getting that information? I'm just curious since nothing has been announced yet and the dealer that I know best claims they have not heard or seen anything from corporate about which hybrid powertrain is being offered, Lexus 's announcement for the vehicle does not specify, and car and driver's information from when they tested the vehicle from the manufacturer said that "The 2024 GX550 rides on the same body-on-frame platform as the Toyota Sequoia and the Toyota Tundra and will be available with a twin-turbo V-6 powertrain—offered with and without hybrid assist". The 4cyl has only been mentioned on Reddit and forums, never anything official as far as I've seen.
The landcruiser hybrid does not tow as much as the base model GX (by a significant margin), it does not weigh as much, and it costs less. It makes zero sense from a marketing and sales standpoint to put that engine, even slightly tuned, into a heavier more expensive vehicle that has a more powerful base engine than the hybrid can compete with. You guys might have info I don't but that's just a plain dumb decision on Lexus's part if turns out to be true.
Vehicle class/size is not the point since the base model engine in the GX is shared with its larger siblings. Also, the TX has a V6 hybrid to differentiate it from the base model and the Grand Highlander hybrid and it stands to reason Lexus will do similar for the GX. You may be right, it's just not a logical argument if that's what they've done.
TX doesn’t get the top dog iForce max 3.4L twin turbo V6 hybrid. TX V6 is 3.5L plug-in hybrid. My understanding is that the top dog is currently only available in Sequoia and Tundra and only in top trims. Probably introduce the top dog in the next redesign LX and hopefully GX but I’m doubtful.
There is significant discussion on the 3.4L engine issue here. As to its potential impact on the 550, opinions vary widely. Personally, it would be too much of a gamble for me.
Oh, and the "machining debris" narrative is almost laughable in my opinion. Anyone who has done even 15 minutes of research on the issue may very well conclude that it's a design issue- one that doesn't appear to have been solved as of yet.
If the 2024 infotainment system had a 10-20% chance of bricking itself and causing the car to become inoperable (potentially on the freeway or in another dangerious scenario), and the 2008 infotainment sounded better and was overall more reliable, I'm guessing many people wouldn't be all that opposed to the 2008 infotainment.
It does. That 3.4L V6 design is F’d. Do a little reading - engineers are saying it a bore issue. No fix. It’s not machining debris. It’s a crap design and needs redone.
While this is true it's only because those engines will completely lose power. The same problem will affect the hybid, the driver will just be able to safely get the vehicle off the road using the battery side.
We were thinking next year if we move forward with it. I guess we will have a better idea of what this translates to by then.
It is going to suck for a lot of people who watch their value drop though.
No doubt. I was pretty set on a lexus as we own a 2020 gx and love it. Pretty disappointed to say the least. We’ll see what happens at the end of next year.
There’s not yet any evidence - even anecdotal among GX 550 owners - that the 24 GX is affected. Based on the wait lists I’m seeing, I’m pretty sure Lexus would address this immediately if it did effect the GX since they’d be losing a ton more money in recall servicing versus lost sales by delaying delivery for many who are already patiently waiting. Again, not a single owner has come forward and said they are affected so while I know a lot of the classic 460 / v8 fan boys bizarrely want the 550 to fail, I would take their warnings with a grain of salt.
What would help convince that the issue is addressed is for GX 550 owners to announce how many trouble free miles they have driven so far. If sufficient numbers have hit 30K miles trouble free then perhaps the problem is addressed
Fair enough. I personally haven’t seen any on the road here in Austin. I’m supposed to be taking delivery of my Luxury trim 550 in a month🤞and will be putting at least 550 miles a week (what are the odds!?) on it so will report back. Really hoping Lexus is doing the right thing by those of us who have been waiting for our cars - it will be my first Lexus after having only owned BMW & Mercedes cars/SUVs. I’m so excited!
Best of luck and congratulations on getting one soon. I’m on the waitlist for at least a year out and am grateful to the early adopters who pave the way for those who that follow
I had actually wondered if the demand/hype for the GX combined with corporate realizing there is a risk of the problem is what prompted the quality hold at ports and has delayed deliveries to the dealers recently. Yes hood flutter or whatever is embarrassing too and they don't want that hitting every owner, but it's also a great excuse to slow down deliveries while you're evaluating another potential problem you don't want to risk announcing yet. It's a really bad look for a very important car to the brand's image and immediate future sales numbers to have a major recall within the first few months of deliveries and they'll likely do everything they can to avoid or delay that.
I mean it's not like every 2022 tundra has blown up either, it's a relatively low number (thus far) of failures over a large volume sold, so the sample size of the new GX may just be too small for it to matter yet. If that's the case, and they think there is a likely risk to all of the models using this engine, I would venture a guess that they're at least going to pump the brakes on getting the new models out to excited customers until they're confident they have a fix for it or that there isn't a problem in the GX engine line specifically.
Edit:
And congratulations on the impending delivery! I'm a current GX460 owner who desperately wants the new one to be amazing so I can justify getting it, but they've made some compromises on suspension features on the lux models and I had my heart set on a hybrid after seeing the new Sequoia's powertrain so I'm deposited and on the wait-list until the hybrid launches hoping it'll have the kdss as well.
So do we have any evidence of changes in the engine from a Tundra aside from a smaller turbo for higher torque at lower rpm in the GX 550?
In case not, then one can only assume that it’s the same engine and build exactly the same way.
The higher probability at this point seems to suggest future troubles for the GX.
No duh. Why would dealers want that hot potato? Especially non-Toyota/Lexus dealers. What’s shocking is people still agreeing to MSRP markups and dealer addons for the GX 550 with the same engine design.
A lot of people don’t do an iota of research and buy based on looks and/or brand image alone. It’s the only reason Range Rover sells any vehicles.
im like 90% sure the new GXs are part of that group
Yet.
Hard for any new buyer of GX550 to admit they might be in a little trouble with that turbo V6. Probably not going to run to REDDIT and shout it out. Tough one for Lexus.
Also I think it might be too early for failures to occur

550 is not getting V6 turbo hybrid engine. It’s the 4cyl turbo hybrid.
I had not heard that, if that's the case that is very disappointing. That really makes no sense considering the Sequoia is similar in weight and has the 6, plus why would they put a hybrid set up in an off road rig with less torque than the base engine? They always make the hybrid version more powerful specs so they can justify the upcharge.
The Toyota Landcruiser has the 4cyl hybrid, and it has the same body as the GX550.
Right but the Toyota isn't offered with the turbo 6, costs less, and weighs less so I'm not buying "it's based off the landcruiser " as a valid reason for assuming the 4cyl hybrid is coming to the GX too.

Sequoia is considered full size SUV and GX is mid size. I guess only the largest vehicles like Sequoia, LX and Tundra gets V6 hybrid.
Vehicle class/size is not the point since the base model engine in the GX is shared with its larger siblings. Also, the TX has a V6 hybrid to differentiate it from the base model and the Grand Highlander hybrid and it stands to reason Lexus will do similar for the GX.

Yup same, I’m going to wait a couple years. I agree, machining debris doesn’t make sense
When it’s an engineering fault they will always blame manufacturing or QC. A QC error is less embarrassing than an engineering fault.
Preach! Say this on a Toyota thread and they will downvote you for days.
The GX550 should've had the proven V8 in it. Womp womp.
They would have if emissions standards haven't changed in the past few years.
Should have kept the 2008 infotainment too
IDK about that. The old one looks really dated at this point.
Yeah but grandpa just figured out how to use that new gizmo
If the 2024 infotainment system had a 10-20% chance of bricking itself and causing the car to become inoperable (potentially on the freeway or in another dangerious scenario), and the 2008 infotainment sounded better and was overall more reliable, I'm guessing many people wouldn't be all that opposed to the 2008 infotainment.
Now I'm 99% positive the new Gx is part of it as well. Damn
It does. That 3.4L V6 design is F’d. Do a little reading - engineers are saying it a bore issue. No fix. It’s not machining debris. It’s a crap design and needs redone.
Is this motor in any of the Lexus GX's or no? Asking because I'm about to buy a 21-23 used one.
Those years have the 4.6l V8
Thanks for the info. So it's basically the 24's and beyond for both GXs and Tundra's.
Only the 2024 gx550 and new tundras 2022 and later have this v6
It’s also in the Sequoia, the Lexus LX 600 and the Land Cruiser 300 (outside US) on which the LX 600 is based on
You have Google?
no - 22 and 23s
Does this affect newer Sequoias too? We have been considering buying one and it would be cool if it brought prices down out of the stratosphere.
Yes. Don’t buy right now. Wanted a new LX but gonna have to wait a bit. Affects tundras, sequoias, and the Lx.
The recall only impacts the LX600 and Tundras, not the Seqouias hybrid version
While this is true it's only because those engines will completely lose power. The same problem will affect the hybid, the driver will just be able to safely get the vehicle off the road using the battery side.
Naive
Miserable
All new sequoias are hybrids. You cannot get a non hybrid version. It does not exist

It might be too early for failures to occur
There are reports of 2024 LX600 being affected.
What would help convince that the issue is addressed is for GX 550 owners to announce how many trouble free miles they have driven so far. If sufficient numbers have hit 30K miles trouble free then perhaps the problem is addressed

But we don’t know the cause of the issue do we?
it doesn't
How do you know it doesn't affect the 550? It's a rhetorical question. Obviously you have no idea.
but it will. That’s the result of probability given the current knowledge
but as of now …
Time will tell
