2024 GX550 Cursed with Tundra Engine Problems

[Vision83]

for as long as I’ve been following the V6 issue, no GXs have been reported to have failures. I honestly think it has to do with where the car was assembled.. American built = recalls. Regardless, I’m glad I picked up a 2025 GX

Many have been reported.

This is the exact same template Land Rover / Range Rover shops use after their 2,500 mile servicing…..

Well now maybe the GX owners will quit slagging on the Hybrid

Sunk Coast Fallacy is real

 

[Thx_1158]

I don’t think you dictum applies. My comments center on a powertrain that is often touted as superior, when the facts are the GX has 7% more HP and 3% more torque than the 250. Not so different and without the stigma of engine failures the V6 faces. Power delivery is a bit different, but most of these owners went in thinking that powertrain was somehow different than the Tundra because it was a Lexus. Now they face the same recalls and the same uncertainty that the engine flaws were addressed.

I saw on YouTube, by an unknown source, that the 2027 3.4L V6 design has been changed to alleviate the problems that have plagued the Tundra trucks

It has that power anytime it wants it, the hybrid has the power some of the time whenever the computer decides you need it.

They say that every year, until Toyota actually comes out with the change and details of the fix I wouldn't believe hearsay.

I saw a great video showing why it is the engine design and not an assembly problem causing the issues with the Tundra V6. The debris in the engine excuse is pure deflection for the design flaw.

Welcome to the asylum.

We probably saw the same one!

Check out the real reason the V6 is failing. Includes links to nhtsa investigation findings. In summary, bad design + swarf.

Toyota Tundra Recall Expansion: Why V35A Twin-Turbo V6 Front Bearing Failures Are Forcing Owners To Shift to Heavy-Duty V8 Iron-Blocks

A massive 2026 Toyota Tundra engine recall expansion reveals why high-load towing cycles trigger sudden twin-turbo V6 front bearing seizures. First-party diagnostic data details why owners are shifting to heavy-duty naturally aspirated V8 platforms.

GX550 isn't a real Land Cruiser.

The T24A-FTS is not in the clear yet. Many members have been reporting issues with the T24A-FTS since last year June 2024. Time will tell, but from what has been reported it's not looking good for us either.
Hearing a rattle noise at low gear acceleration.

Sounds like the direct injection system, people thought the same of the 3rd gen tacomas. Most of all modern Toyotas have the similar rattle sound, they just mitigate the sound with better insulation.
