Another 2017 with P11EE code

It’s every time someone has a problem. Statistics are great until someone has them not in their favor.

 

Please, add to or do not post if it is NOT of the issue at hand. The issue at hand is what happened and why. Year? Model? VIN first #? Oil pump recall done? Within/outside of the 2016-2019 window?

Please folks... Let's stay on track and work this through.

My current theory, from several sources of info, leads towards the oil pump. I do hope we can work this down the chain and figure it out!

 

Not sure why you bring up the Mexico plant when talking about the engine quality. Pretty sure the engines are built in Huntsville Alabama......

 

^ This right here for the win, I’m a Quality Analyst and I could not have said it better myself. Get over it shit happens the numbers are so insignificant that Toyota is not even recognized it.

 

Just another piece of the puzzle and interested if other are the same.

Update edit: Huntsville boosts of making 1/3rd of 'all' Toyota's engines

 

Ah but they do recognize the failure and are repairing it at their cost, including rental. Again, please, if you haven't had the failure or no relevant information leading to the cause.. resist comments and move to the next post.

 

Update:
P11FO (cylinder five) reported of same issue
Confirmed crankshaft issue on his
Crankshaft Sensor is a known issue.. curious how this relates.

Another mechanic has weighed in with possible oil pump issue or back drain of oil, which he surmises could (can) lead to bearing (crankshaft) issues. He's the second of my trusted wrench capable associates to chime in on oil flow..

 

You would 100% have a different tune on this if your taco blew up a few thousand miles outside your warranty and Toyota stuck you with a 5k plus repair bill.

Its ironic you are a "analyst" but are basing your post on assumptions. The truth is none of us know how big of an issue this is. It could be 1%, it could be 5%, it could be 10%.

 

What do you mean crankshaft issue? You spun a main or rod bearing? I don't recall anyone spinning a bearing.

 

I don’t think this is an oil issue. I think it’s a poorly manufactured valve/valve stem issue. If it’s an oil flow issue then that should be attributed to design and we’d likely see this on a more widespread basis.

are they familiar with this specific issue on the 3.5 or are they just throwing out a guess? The number one fix for these codes is a new head that ultimately provides new valves/valve stems. That has at least been the fix in 100% of the posted cases I’ve seen. I’d suggest the mechanics are thinking generally and not in the specific case of the 3.5L.

 

There aren’t enough failures to spot a trend and ascertain root cause. Toyota might be able to come up with the root cause if they do enough warranty repairs.

 

I've conversed 3 so far that started as the head and as they pull the engine apart found deeper issues. Those 3 lead back to the crankshaft bearings.

 

Have to disagree with this. Every issue has a root cause, if they were none we'd have prefect engines. We don't and with assistance we may just find it. And again.. if you have nothing to contribute as to what it could be.. please just move on.

 

How do you know there aren't enough failures? People need to stop speculating so much on these failures. When motors fail before 60k the mfg wants to know why as soon as possible even if its a small amount of cases.

 

I have a crystal ball.

That and the fact there aren’t a shit ton being reported here. Duh

 

There's a few threads here as well as other places that show the issue has gone beyond just valves (or stems). I do see most have had that replaced as well, yet not all that I have read or conversed with. Is it the majority.. juries not in on that as of yet.. you could be right!

 

This is the internet. Your issue is statistically insignificant. Sorry you don’t like it, but the truth hurts sometimes.

 

lol that doesn't count.

AGAIN. Only Toyota knows how many early failures these motors have. People can continue to try and use their opinion as facts but it does nothing to prove their point.

Take off the "I spent 45k on Toyota so it must be the most reliable vehicle on earth"glasses.

 

This is the truth. I would love access to their data.

 

Quick update:

It turns out even as it is... Toyota knows the issue and what needs to be done to resolve it. Had a great conversation yesterday with a lead Technician and he explained what happened. I will have the truck back in a few days as they are pulling it apart and replacing the valves. Nothing I or anyone can do to avoid or detect in advance. Good to hear Toyota knows of it and has the procedure in place for repair. Extent of damage due to the valve is yet to be determined as they continue to open it up and test components.

I'm disappointed that so many in this group are not only unwilling to assist another yet down right snotty about it. Folks over at My F-150 forum rally around and truly help each other. To those that have helped or encouraged along the way, a big Thank You!
