Official Reveal Thread 2025 6th gen 4Runner

[FoundedSine14]

According the SuperfastMatt on YT, since the new Tundra and new 4Runner share the same platform, the front suspension can be swapped to essentially get OEM long travel on the 4Runner. I'm curious to see if anybody does this and how it works
Here's the video at the timestamp

The V35A is now 5 years into production in the GA-F platform and about 8 or 9 years total. Still not fixed.

Is the oil starvation you mentioned the issue for the V35A as well?

Why has it not been fixed, does it only happen in rare cases or high mileage models?

 

[thatoneguy]

The advantage to the SDM is that it does not require fluid flow to operate, so it does not have a risk of overheating and can be at least theoretically run in the unlocked position at any speed without issue. eKDSS and older KDSS would close the valves as speed increased to ensure that fluid temperatures didn't outrun the natural cooling of the system. KDSS is not great for high speed offroad use. SDM is. And SDM is probably a lot cheaper to repair if something goes wrong, although KDSS has proven to be very reliable.

It has? I've seen too many stories of shelling out $3,000+ once it goes out, sometimes when barely outside of warranty, and often within the first 100k miles. From what I've read, it seems borderline dicey to expect KDSS to last the life of the vehicle, similar to air suspension on GX470's.

No KDSS was a non-negotiable point when my dealer was finding a non-allocated 2023 for me. I would be totally ok with a front electronic swaybar disconnect, though.

Am I the only one that's sad this thing got 4-5" longer?? Just think of the approach and departure angles that could have been! And I like reasonably sized SUVs, dammit!

Oil starvation is currently perceived as the issue for the V35A spinning it's bearings. I've been following along with it on the Tundra forums as I've always wanted a Tundra.

In the Tundra world there's a user over there who is going to do a tear down of a V35A Type '21 he got his hands on. No one outside of Toyota knows why this is happening. It also appears to be between 20k and 40k miles (maybe a bit higher, can't remember exactly) and I want to say the average failure mileage is around 26k. Most of these failures have appeared to have occurred in trucks built prior to late March 2023. Time will tell is if this stat holds true as trucks built later than that should be hitting this mileage. The same user doing the tear down seems to have some sort of knowledge about what the actual failure rate is and says it's less than 0.5% of all trucks. He got hit with a cease and desist from Toyota about what he was sharing, so he's a bit more tight lipped now. I can't speak for the V35A Type '17 (LS 500) as I haven't been following along with that vehicle.

I'm not too concerned with the V35A anymore as the failures have died down and there are plenty of used Gen 3 Tundras popping up with over 100k miles without a rebuild. Sure 100k miles is a low standard by now, but that also leans toward the failures being more of a fluke than an inherent design flaw in my opinion.

What honestly concerns me most about the Tundra now is the overall fit and finish issues inside and outside the vehicle. I'm curious to see if those will be a part of the new Taco, LC, and 4Runner as well as it seems any Toyota redesigned 2020+ seems to have some odd ball issues that haven't affected previous Toyotas - see the current gen Highlander with the front bumper that just falls off for no reason.

Speaking of the Highlander, the T24A has been it since the 2023MY, now I haven't exactly looked, but I think it's been relatively smooth sailing with that engine aside from some sensor issues when it first launched, but don't quote me on that.

Edit: I see you're in DFW, so is the user doing the teardown. Go bring him some beer as motivation to complete the teardown, we're all patiently waiting.

Yeah that seems to be the thing with the GA-F platform, increased length, decreased interior space. It's odd.

 

[BIGpharma]

If I got the TRD Pro, my first "mod" would be to color match those fender flares.

 

[Inv4drZm]

The 4.7" overall length increase minus the 2.4" wheelbase increase means roughly 2.3" is dispersed over each front and rear bumper lengths. Basically each bumper increased by 1.15"..... Tell me how that affects anything offroad.

The 2.4" wheelbase increase won't be a detriment offroad either.

But the 500lb hybrid system standard on TRD Pro and Trailhunter models would be a detriment I would think.

1. They're called "approach and departure angles", and they do get worse with every unnecessary inch. If inches didn't matter, people wouldn't put 2" larger tires on to gain 1" more ground clearance.

2. Depends who you ask. Straying away from ideal wheelbases does have effects. Breakover angle lowers and the chances of getting hung up on crap rises. I have a friend that offroads a crew cab Colorado that doesn't think wheelbase matters for wheeling. That thing smacks everything between the axles.

3. Yes, too much weight is bad. Although, in this case, that weight gets you 465 lb-ft of torque at 1700rpm, so it might be worth it to some. Instant torque is really nice offroad, and both versions of the new 2.4L improve it much over the 4.0L.

They're throwing the T24A in quite a lot of vehicles, far more than the V35, both in number of nameplates and annual production. Toyota should know how important it is to their reputation at large not to screw up that engine. Presumably, they did their homework.

For those that really worry about first year problems, the 2025 4Runner being on the third or fourth year of a newer engine design should help fears a little. Not the first year on the transmission either.

" It's uncomfortable for a lot of current 4Runner owners to accept that the new one is a vast improvement over the 5th gen. Again, natural and normal for those financially and emotionally invested in, let's be frank, very expensive vehicles."

In your nsho, which I think is mostly psychobabble. It's unproven. It's more complex. It's a bunch of things, but entirely unproven.

And what makes you think everyone who owns a 5th gen is invested in any way at all.

Fwiw, I sold my 2016 to my stepson and bought '24 TRD OR Prem w/KDSS. It's my vehicle. It's not my baby, it's a truck.

My wife refused my offer to dump her '16 Avalon Touring and write a check for a new Lexus of some sort. She is sentimental.

Me? If I find something I like better I'll write another check, get rid of the '24. Heck, I might give it to my stepson. Then I might even buy a new '24 in each color. It's only money and I have lots of checks left.

Don't go painting everyone with the same brush. You are embarrassing yourself. Some people are more rational than you give them credit for.

Not really embarrassing myself. Just pointing out the inherent bias that I believe many owners are too afraid to admit. Again, it's normal and expected. But it would be a shame if yet another forum became an echo chamber of the same lame repeated thoughts.

You can dismiss it as psychobabble and as me "embarrassing myself" but again it's expected for people to feel uncomfortable when their biases are made visible

Yes. Absolutely. Failure rates are very low. Out of the hundreds of thousands of KDSS systems, the failure rates are few and far between. Based on experience on this forum, the failure rates are probably one or more orders of magnitude lower than air suspension failures ,TRD Pro shock failures, and XREAS failures.

I would not own an 5th gen without KDSS unless I replaced the full suspension. The handling without is not something I would want. When I test drove them back to back it was an easy decision.

I'm guessing at oil starvation, but yes this is specifically an issue on the V35A. They are experiencing a relatively high rate of bottom end failures on the crank bearings and it's mostly the front most crank bearing. I don't know the specific oil path on that motor, but it is the most logical reason for the main bearing failures.

Pretty recently there were over 100 engines on back order in the parts system. Not sure how many are failing globally, but I'm hearing the same thing from GCC members. 100 on backorder is a snapshot and it doesn't tell me a lot, but it's quite a few to have open orders waiting for at one time for pretty new engine.

It could be caused by other issues like the main bearing bore being off center on the last bearing, could be a crank issue, could be assembly errors, or many other things.

The GR series has had its share of issues too early on. The 1GR we have now has the advantage of many years of small improvements. But sometimes toyota just lets known problems go on forever without fixing them. The 5.7 cam tower oil leaks are very common and pretty darn easy to fix, but Toyota never fixed them. Toyota also never fixed the 5.7 timing chain tensioners, never fixed the diff needle bearings despite thousands of failures.

I hope Toyota fixes the V35A bearing issues. Maybe it's already fixed. It's just a black box with no feedback going out to buyers to ever know if something changed and what that was.

 

[Jetboy]

FWIW - the rear overhang had to get bigger. It needed to fit a larger spare tire. There's only 2 ways to do that: extend the rear crossmember back or put the tire on the rear door. Can't have the tire on a hatch. And it appears Toyota didn't want to put a side opening door on the rear. Given that it needs a full size spare and it was going to have larger tires - it has a minimum of about 40 inches behind the rear axle to fit a tire, panhard bar, and rear bumper. As soon as the larger tires went on it was pretty close to a given that it was going to lose the departure angle a bit.

Plus side - it should fit 35's with no mods. Probably 37's with minor mods. I think that'll solve the angle issues.

 

[KimchiJae]

There's probably a meme GIF somewhere that's appropriate to describe the fandom's reaction whenever there is a redesign.

But I remember all the "No V8. I'll never buy another 4Runner. Toyota is doomed." and the "so glad I bought a 2009" posts.

Change is hard.

At the rate Toyota redesigns the 4Runner, there will be many, many years for folks to accept the 6th Gen. And some never will, and that's OK.

I would like to see what the Platinum looks like and will be interested to see pricing when it's available later in the fall.

Yes fully agree -- change IS hard. And you're correct some may never come around the 6th gen and that is indeed perfectly OK.

It's been meme'd to death but we all have seen the "3rd gen best gen" 4runner crowd. Other examples are the "real land cruisers have solid front axles" crowd that don't even believe in the J100 LC as a real LC.

but as time goes on, new members are welcomed to the community and current members try something new. Knee jerk reactions become murmurs and change becomes normal and turns out the (insert new Toyota model here) wasn't the end of the world.

That is until the 7th generation 4Runner is announced in 2040 and all the 6th gen owners throw up their arms and we have this same conversation all over again lol.

They're throwing the T24A in quite a lot of vehicles, far more than the V35, both in number of nameplates and annual production. Toyota should know how important it is to their reputation at large not to screw up that engine. Presumably, they did their homework.

Bingo. The T24A has been in a lot of vehicles already and the inline engines lend themselves to reliability AND repairability/maintenance (compared to V-engines)

I know some have been disappointed with the lack of the V35 as an option in Land Cruiser / Tacoma / 4Runner but I have always preferred inline engines compared to V engines.

half the heads, half the amount of cams, half the gaskets, two thirds of the amount of valves, simpler timing components, really the list goes on.

More importantly when turbocharged, half the amount of turbos (although I recognize there are biturbo designs for some inline engines) and FAR simpler plumbing (perks of having one exhaust header)

I've gotten odd looks when I have said I greatly prefer the T24 hybrid than the V35. There is so much dogma about having a higher cylinder count must mean its the superior engine.

Feedback

Reflecting on years of 5th Gen posts complaining about the T4R stance. As the saying goes, be careful what you ask for. Toyota appears to have "over-corrected" with the pushed out 6th gen tires.

Not crazy about the larger size of 6th gen but overall breathing a sigh of relief for the future of the 4RUNNER brand. Although I have not seen new LC and GX in person, photos of those trucks show unpleasant (really awful) exterior designs. The 6th gen T4R appears to have the best styling of all three.

They showed a photo of the Platinum and what the 3rd row looks like (screenshots attached).

I remember when black trim signified the base model. Black door handles, black mirrors, black trim.
