P11ee Tacoma TRD class action recall with replacement while being repaired

I have a 2022 58000 miles and code hit it still runs ... bought new.
Is there a lawsuit on this?

 

No. Sucks it happened to you but you should still be under warranty and get it fixed free. What else do you want?

 

Going from throwing a code straight to class action lawsuit , on a truck that is still under powertrain wty ? I’m confused .

 

i was hoping the '22's were not affected by this.

 

Ahh good to see this issue is still alive and well, and not limited to certain years. I thought I was safe and folks have also been told the cylinder head had some updates but maybe that isn’t true.

 

Do you have a tune? What is your driving style? Do you get high in the revs much or do you stay pretty down low and putt around everywhere?

 

Is this the code that required replacing the cylinder head?

 

Perfect reason to spend $1700 and get that 10 year 100k Toyota warranty.

 

I’m going Duke Of Doubt on this one

 

I am curious what you think might be happening based on someone's driving style - the occasional high rev vs. putting around at low RPM's?

 

I don't have enough info to make any assumptions but I think it would be a good idea to compare driving styles between failures. Nobody ever talks about how they drive when this issue comes up.

There was a guy on here around a month ago who posted up that he had one of the imbalance codes at around 140K miles. Said the truck still ran fine but maybe stumbled a bit here and there. Pulled the intake manifold off and saw lots of carbon around the valves on the bank that the code was for. I never saw a follow up post, and nobody else commented on that thread so it went nowhere. But he was starting to think the carbon buildup was the problem, not the valve itself.

I'm mainly interested in driving styles to see if they could contribute to this. I don't know that guy's driving style, nor do I know anyone else's, but it would be interested to see if the people who stay at low rpm all the time are more likely or less likely to have the issue. I personally drive mine pretty hard and am always revving high just because. I like to think that could help keep the issue at bay but I don't really know unless I can compare with others.

 

To elaborate a bit, something I find interesting is that this repair always "needs" a cylinder head replacement and a new valve on the affected one(s). But are the diagnosing dealers looking for carbon? I don't really know. The code is for the imbalance of the cylinder and essentially the cylinder leaking out of the valve, but if the valves are coated with carbon, that ain't gonna seal....just curious if there is maybe more to the issue than a simply unlucky head/valve job. It's quite the expensive repair so any sort of better news would help.

 

It's not carbon. The valves that are leaking are exhaust; not intake.

 

That’s what they say, but the code is for “cylinder imbalance” - if you had carbon on intake valves couldn’t that still cause an imbalance or appear as a leak during a compression test?

but yes I do see your point, when they change valves during the big procedure, it is exhaust valves they are changing and those would not be carbon coated or wouldn’t be what was seen on the intake side at the very least.

 

The carbon buildup is minimal on intake valve seat face and won't cause the leakage. You'll see more buildup on intake valve stems.
Here is toyota head and intake valves from the engine which intake is always full of oil.

 

I guess the d4s system works

 

Some folks argue that gr2-Fks's direct injection is causing carbone buildup.
Is not. If you monitor d4s system , you'll see Direct injection Only mode is on at 75% load +hot idle cleaning cycle
The rest, Port and Both. We drive most of the time in Both mode, where Port injections is the main source of the fuel. Need to look at
Injection timing and volume for Port and Direct direct. Even in Direct mode, Port injectors are pulsating and deliver fuel.

 

If this problem is more widespread on tacomas with stock tune , then high revving/high rpm plays a role. Stock tune = gear hunting = highrev/high rpm . If it occurs on both tuned and stock, then I think it’s design flaw . It will happen it’s only a matter or when. Just like the coolant plastic bypass leaks. It’s only a matter of when .

 

My 23 is always trying to be in the highest gear possible meaning the truck typically stays at lower rpms. Yes, it gears hunts a bit when you need to accelerate but the rpms never really go above 3500 rpms unless you really step on it.

Even going from say 70 to 80 on a hilly highway, the truck won't really rev out much when it down shifts, and this is with a lift a bigger tires.

I do however with every car I have ever owned is really rev the motor out once in a while. I do it at least every few weeks. Getting on the highway, step on it and get a nice gradual pull almost to red line.

 

I bought my 21’ with 7 miles on it, drive it hard getting on the highway just about every day, that’s why I got the 6MT… have a lifetime power train warranty, and plan on keeping it for a loooonnnnnggggg time. I’ll let you guys know if I get this issue.
