I just took an enormous dump.... and it looks exactly like a BMW.

 

Thought this might be of interest to this chat as it seems it is becoming a larger problem with these turbo engines

 

The premise is that when the customer paid for oil changes the recommended interval was 5K miles. Now that everyone is offering 1-3 years of free service, the interval is magically 10K miles (hell, I had a 2012 BMW 740, and the dealership tried to bully me into foregoing an oil change past 10K miles because the oil life indicator said everything was fine). It's all BS, and they know that the problems caused by delayed oil changes will only arise outside of warranty. It's really shameful, but they also claim it's to help the environment, gimme a break. 5K max interval, 1 year max regardless of mileage. Changing the oil is so cheap compared to the inevitable problems caused by not changing the oil.

 

This video goes into why manufactures have moved to a 10k oil chain interval, it's because it does lower the lifecycle costs from a government perspective. For compliance purposes. But most/all people should 100% do 5k oil change intervals.

@Hamby86 , yeah I saw that one too. I find it interesting that there are seemingly more failures on the Tundra/LX/TX products than with the LS500. I think it's possible they moved engine manufacturing sites when they put the 3.5L into these other products. Like for the LS500 was so low volume so they were probably on a hand made, low volume, line. So tolerances were tighter, and Quality Assurance was better. But then they moved the engine line to a new facility for the ramp in production for the Tundra/LX/TX... I know I saw another Daves Auto Center video where they had a V8 from a merc AMG, and that bottom engine cam cap/ladder frame is machine to the specific block, so you can't just replace it with a new ladder. You have to rehone the entire block-to-ladder cap bore so they are all in line before you install the crank bearings and final assembly. So if Toyota has quality escapes from the factory due to their bore honing machines not being calibrated correctly they should be able to identify the exact car VIN's and issue a TSB or Recall notice.

 

The toy and lexus engines have slight differences. I don't know if that difference includes the shortblock or heads. Whats odd is this problem is surfacing in Lex very recently. I'm confident the V35 engine isn't handbuilt.😂

 

With the news of Merc and others possibly embracing the V8 again, it makes me wonder if the next generation of the LS will go back to the V8. I currently have the 460, and with how little I have invested in this vehicle at this point, I plan on driving it for quite a long time, hoping that the next-gen LS will be something really special.

 

The next Generation of the LS, the LS500 is a special car.
LIke your 460 is for you and others, most of us are enjoying the car very much and not experienced any blown engines.
The next generation LS or other flagship may be a big departure from anything we are familar with and at a price point that might be very high.
I bought my 2019 with 28k miles on it with 40% off MSRP. Yes, used. Not here to argue but I don't go on to the 4th gen forums for any reason.
I have not had any issues as the car is now at 41k miles. In fact, I got mine without it being CPO and thus did not pay for the extra warranty either. the car had but a few months left on it.
Come January if I have no issues I would have had it two years and "Win". If my engine blows I have the 7 year, 70k coverage. Beyond that Im screwed. I'll deal with it.
Meanwhile what % of LS500 are problematic with the bearing seals?
NO car is perfect and we 5th gen owners understand this car is a much lower production in volume and few "enthusiasts" exist because of it. If there is an issue is it systemic to the model or a few one offs?
We dig you and the 460 crowd are loving your cars. Wishing you and others many happy miles and smiles. Almost seems like your gloating that others might have an issue while you have not. This is a LS500 thread. How else should we take it?
Not like your really contributing any knowledge here. Your not asking any questions either.

As for Mercedes, The EV craze, the EPA thing for better MPG, and many notable supply chain issues of the AMG/V8 in post pandemic were reasons for the pull back. If demand is there and likely supply chain is back to full capacity I would think in the name of profits they would do it.

 

Oh no, this is the issue with text which I do not think conveyed my intent very well. I legit love the LS500, and I could see myself totally getting one for sure. I think they are beautiful! I just came across that video and thought it was relevant to the conversation here.

 

We get some "Interesting" participation from time to time of folks compelled to tell us all kinds of things not always relevant. Intentions matter an when called out a gentleman such as yourself brings clarity and context.
Thank you!!!

Could this eventually be expanded to cover all of our engines?

 

Um, Yikes!

 

Yeah, I just saw this too. Apparently this is a google doc where Tundra owners have been keeping track of the failures. (https://docs.google.com/spreadsheets...#gid=780956012), At least Toyota is doing something about it. Also glad they found the root issue. That means it's not a design flaw, but a manufacturing issue (so hopefully if you don't get the issue in your truck/car) then you're good???

Again, I think the LS500 is going to avoid this recall because they probably produced these engines on a different factory line than the Tundras like I posted earlier. The Tundra sold 104,000 units in North America in 2022, whereas in 2018 LS500 sold 9,300 units that's a lot easier to maintain quality standards at 9,300 units vs 103,000 units. (11x more production capacity needed for the Tundra, not to mention the LX line)

I also love the LS500, and someday hope to own a high mileage one... just think this thread is more about documenting issues people do have so when these cars start to get 10+ years and 150,000+ people can go into their new-to-them car purchase with eyes wide open. We're all DIY mechanics and Lexus fans here!

EDITed for failure history (based on this thread):
MHB1535 posted on 01-23-21, 2018 LS500 FSPORT, purchased in Sept 2018, 1st engine OEM at 21k miles, 2nd was from debris in the rest of the motors at 25k miles, was lemoned lawed by dealer.
Chgidem posted on 07-08-22, 2018 LS500 bought CPO at 29k miles, failed at 34k miles, knocking when accelerating, no updates.
Profitwho posted on 12-21-23, 2019 LS500, ??? miles, knocking engine no updates

 

My Vin was not part of this recall.

 

Are all of these engines made at the same facility?
Seems silly to make them in Texas, them ship them to Japan, then back to the U.S.
As mentioned above, manufacturing issue might just be related to U.S. built engines.
I’m happy with my ‘20.

 

Hope this doesn’t spread to other models:
