2GR-FKS engine failure

Even worse lol

 

Maybe for you?

have you seen that thread with “reliability” poll? Most tacos have absolutely no issues.

 

Can you name a perfect mass produced engine that has no issues.

 

20 people on the forum had engine issues and folks lose their shit.

 

Mine blew up at 100,000....valvetrain component failure. Needle bearings got into the oil pump, and then caused catastrophic engine failure.

Oil was changed every 5k with Toyota synthetic and filters, dealer had record of all 6 years of service...so it wasn't from lack of maintenance.

However, my experience with Toyota was quite different. They turned into absolute A-holes.....they denied every aspect of responsibility and despite having all the service records, claimed I mistreated the the truck and that catastrophic failures (and I quote) "do not just happen, Toyota engines are the best around and do not fail without any significant reason of fault of the owner"....that was per the Toyota brand engagement rep via email to my dealers service manger.

The dealer owner actually stepped up and offered me $2500 in rebate off the job towards service and labor.....but I've yet to see that check either, almost 3 months after the fact.

Now my wallet is $12,686 lighter......thanks Toyota!

 

Either way, the failure rate is no higher than anything else in production. These are mass produced, cookie cutter assemblies. Tooling wears out, casting and machining are inaccurate, (relative to a hand built engine) and factory workers are not infallible. In a perfect world, these 3rd gen Tacomas would have been fitted with the 2UZ-FE, (probable Toyotas best engine ever) but there are far more high mileage vehicles running around with the 3.5, than those that have failures.

Take for example the 3.5 V6 in Honda vehicles (especially in the early 2000's), which also had significant exhaust valve/cylinder head failures due to valve adjustment problems. (I was a tech during this time) People constantly said "but.. but.. but.. its a Honda, it should last forever". Nope.

 

Feel bummed for those that have had failures.

Just throwing stuff out there. (Non plastic engine components)

First, and most importantly, which fuel fuels your Taco?

If it’s 87, I would have to think that that could lead to some possible scoring. Particularly those of you who baby your Taco’s powertrain, but then go WOT balls to the wall on a 100°+ day when you need it most. And yes, your engine’s current oil life is past 3500-4,000 miles as well(my limit for WOT runs). 91 or above will keep detonation and its effects in check. Sucks to have to pay for it, but it is what it is. I’d rather burn 91 in the combustion chambers.

Has anyone heard of a supercharged 3.5 failing?

That valve train failure is bullshit on Toyota USA. 460 Off Road is correct, these power plants are assembled here in the states. So were the TTV6 Tundras. I believe him in what he says. They need to put some competent people on the assembly lines. They should be helping you out. Fucking bastards for greed. I’m so ready for Kia’s TTV6 truck if it comes stateside.

I have decided my SR5 is going to sport the KDMAX PRO10 for its lifetime. I’ll be one of the last of the Mohicans.

I like the tune and the 3.5 that much

 

"stop gap" um yea, lol

 

Another car engine?!

 

To all the haters of Toyota, go buy an American truck. Report back on reliability.

 

It's not just 10 people though, and the amount of documented engine failures with the 2GR-FKS on this forum is surprising given how new these trucks still are. I know it's anecdotal, but I've had Toyota techs tell me they're seeing bigger issues on the 3.5s compared to the 4.0s with twice the mileage. There's very few threads discussing low oil pressure with steep grades on the 1st and 2nd gen sections (maybe some issues with the 3RZ balance shaft).

I don't claim to be an expert, but I'm not buying that the only difference is the stroke between the 2GR-FKS and 1GR-FE. The former was always designed to be transverse-mounted in a FWD platform like the Camry or Avalon, where they have been extremely reliable by all accounts. They do appear to have top end oiling issues in the far heavier Tacomas, however.

Even if the displacement is the only difference, I think people underestimate what a big difference the extra low-end torque makes for such a heavy vehicle. Dropping the 3.5 in the 3rd gen Taco will always be a mystifying decision to me. After all, there's a reason Toyota developed the 4.7l 2UZ for the Land Cruiser/Tundra/Sequoia instead of just using the 4.0 1UZ from the LS400.

In any case, I don't think Toyota will ever admit to an official failure rate of any of their engines, so we're always going to be speculating to an extent.

 

Again, I'm not sure what your source is for the bolded claim, unless you're the chief engineer for Toyota or something.

I will concede that there is the "don't make em like they used to" adage belies an element of survivorship bias. If you look into it, there were more relatively low-mileage catastrophic failures than most would care to admit with such legends as the 5VZ, 5SFE, 2UZ-FE, 1GR-FE, etc. (thrown rods, head gaskets, etc.). It's hard to argue with the plummeting reliability ratings from Consumer Reports and other reviewers going from the 15 to 16 model years, however..

 

I know it's an old post, but I think Subaru got a bad rep in the US starting in the 2000s since they took arguably their least reliable engines - the EJ25 - an put it in just about everything. The NA version had the infamous graphite head gaskets that inevitably failed around 100,000 miles, and the turbo versions became notorious for ringland failure, among other things. The smaller-displacement 4-cylinders that were more popular in other markets like Australia and Asia were more reliable IMO. The CVTs that are so popular here nowadays don't help either.

Besides, people forget how bulletproof the EJ22s were in the 90s/early 2000s Imprezas. They were arguably up there with Toyota and Honda in that era.

 

There has been a total of over 1.8 million 3rd gens sold in the US.
That’s 200,000 more than the 2nd gen despite being 3 less years of production.
Thats DOUBLE the number of 5th gen 4Runners within the same time period.

I would bet More 3rd gen trucks get overloaded, modded and abused than any other midsize offering in the last 5-6 years including 2nd gen Tacomas.

The average owner isn’t on TW doing 700 mile oil changes and black stone oil analysis every 3 weeks.

Get out there in the real world, in the mountains , on the trails, the only other vehicles you’re probably more likely to see out there in the roughest parts is probably a wrangler.

What ever reliability shortcoming you think the 2GR has compared to the 1GR is likely not even statistically significant enough to worry about.

 

2GR-FKS = 4 camshafts
1-GR-FE = 2 camshafts

 

So a 3GRFE has 6 cam shafts? Cant tell if this is a joke. Toyota has had twin cams since forever.

 

It was a mistake dick, chill. Like he’s looking to pounce at a moments notice LOL
