The used the words "of a certain size" when they talked about the debris. This undoubtedly has been put there for a reason and needs to be legally defensible when they get sued (20+ lawyers when through this before it was released). I read that as "we designed it correctly with allowances for some debris contamination of size X but our poor process and our poor suppliers introduced particle sizes above X. This caused engine to grenade. Therefore we tried to improve process and even introduced a new bearing with new metallurgy (maybe a coating) to better handle the larger particulate size". My uneducated opinion is (A) with CDE as things that made the situation much worse and significantly lowered the margin of error. But I'm an idiot so who knowsthey put a new bearing in it to try and resist degradation from the combination of
(A)-machining debris,
(B) a high torque engine being harder on bearings,
(C)the low viscosity oil speced for mileage reasons
(D) fact that during the first break-in period turbo engines tend to dilute the oil with fuel more due the higher pressures in the cylinder and more loosely gapped rings further washing out your oil's viscosity, and
(E) the 10k mile or longer speced oil change regiment with no break-in oil changes
i suspect if a few of these variables were changed this would never have happened, ie no damn machining debris
its never one thing that leads to catastrophic failures, there is always a constellation of factors

Yep. If there is one thing I am not doing it’s this 10k mile interval. 1k for the first and then every 5k mile religiously.
No offense, but you got cold feet on worrying about a LX and got a vehicle that’s riddled with problems instead? Why do I find this hard to believe?
I'm aware of the common problems that Rivians suffer from, but so far so good and zero issues. I'll choose minor glitches over a potential engine failure day. Don't want to go through a long block replacement on a 100k plus vehicle either. Also, we are getting home solar and an EV allows us to get more panels, so it made sense. It's obviously no LX, but I'll patiently wait for a true fix.

Does anyone know if Toyota has refused to fix/replace a TTV6 that has self-destructed after the warranty has expired? With what we know now about the engines/oil, my guess is that Toyota will be replacing these engines under some "warranty" program for a long time after the warranty has expired or there will be a class action lawsuit that seeks the same results.
I for one, like my 300 and although I am on the list, I would take it on a long trip and not worry about the engine as much as I would worry about being in an accident.

I've been following this for a while since it started happening on Tundras and I don't think I've ever seen Toyota refuse to fix an engine. Seems like they're taking care of people.
I've even seen a few posts by guys whose engines blew, Toyota replaced them, and then the replacement engine blew, and it was replaced again... not the most confidence-inspiring example though haha. May have just been short block replacements early on.
The main reason I didn't buy a newer Tundra is because I regularly tow a trailer off grid and I'd rather not have to deal with a blown engine in the middle of nowhere and have to get a tow for both a trailer and the truck. If I was just sticking to civilization I'd feel ok buying a GX or LX.

My LX might see a dirt road ever now but I totally agree about going out in the sticks. I'm never too far from a tow truck or out of cell coverage.

186K.
Never ever would buy a rivian or a tesla for that matter. These evs are riddled with many more issues than an lx and rivian is just hanging onto a thread like nissan. Kind of like the qx80 over lx argument. They are not a lexus despite looking good on paper. Not to mention huge depreciation on those 2 vehicles compared to a lexus
Right on! An Armada or Qx80 are maybe good deals only if you take off at least a 10grand from msrp right off the bat.
It's your money, you can spend it how you like!
Agree, it's no LX as I mentioned previously.
Agree, it's a bad financial decision to buy any EV new due to rapid depreciation. But if you leverage the depreciation, you can get a very lightly used, low milage example in the 60k range like I did. There is not enough value when spending 100k on a new rivian, or any high end EV(model X, lucid, etc). The materials and fit/finish are worse than what I would expect in that price range.
Thankfully ours has been riddled with a total of zero problems, but it's only been 8-9 months so time will tell.
Good luck with your Rivian. My wife’s quad R1S is a POS. Tons of problems: suspension issues that haven’t been resolved, bricking, messed up stereo and climate, cambor issues that keep reoccurring, etc. etc. etc. Worst part is that there’s only one service center near us that is always booked out 3+ months, and is run by a bunch of self righteous hipsters with no customer service experience. For some reason my wife still loves her Rivian, but I’ll never give that damn company my business again. For what they charge for the R1S now, it’s a shocking piece of junk. Luckily we bought hers before the price increases. No way in hell would I spend more than the 74 we paid on that SUV.
Let's get this thread back on track. I recommend starting a new and dedicated thread if you are so inclined, or just message me with your opinions.
Any updates on this recall?

I don't think this a machining debris issue. I really think the debris in engine is from bearing failure from low viscosity oil and or problems with oil circulation in the engine. What do I know? This is not good
