What's wild is Hyundai had this exact same recall for "debris left in the engine" which caused wear on the connecting rod bearings. Hyundai said it was casting material, Toyota blamed machining material left in the engine. Neither makes sense as the oil filter would filter both out pretty quickly and damn sure wouldn't still be in there tens of thousands of miles later. When Hyundai replaced the engine on my wife's old Sonata free of charge I talked to the mechanic. He said it was just shit quality connecting rod bearings.
Better than GMs recent recall of over 400k trucks for transmission issues causing the rear wheels to lock up. The problem is premature transmission valve body wear. The fix, was a software update to monitor valve body wear and put the truck in limp mode where it can't shift above 5th gear approximately 10,000 before a lockup would occur. GM was made aware of the problem in 2001 by an Engineer, conducted an internal investigation, GM concluded the problem wasn't severe enough to cause a safety issue so they decided against a recall, AND KEPT MAKING THEM with the same known problem. In 2022 they installed the software on new trucks going forward. It wasn't until the NHTSB came to them with cases of accidents cause by transmission lockup that GM issued a "voluntary" recall. But GM is perfectly intent with knowing they were actively producing transmission that were going to fail.
