In May, the NHTSA released recall report 24V-381. In it, the authority explained that more than 100,000 vehicles, a group of 2022 and 2023 Toyota Tundra and Lexus LX600 models, might suffer internal engine damage from machining debris left over during production. The primary symptom is main bearing failure. At that time, the company did not announce a recall remedy. 

Kris Buchowicz is a Toyota master diagnostic mechanic. This week, he posted a reel showing us exactly what the notorious main bearing failure on the newer Toyota Tundra sounds like.

As you’ll notice in the Tundra clip, bottom-end internal engine component failure has a particular sound. You’ll hear a low but measured tapping that quickens with RPM increases. It’s almost like a “Wheel of Fortune” spin:

Unfortunately, the mechanical solution for this issue is a rebuild or replacement. Either is both incredibly costly and very laborious.

Last week, in response to the issue, Toyota announced via the NHTSA that it would authorize its dealers to replace the engine assemblies of the affected models free of charge. Owners were sent letters affirming this remedy on July 29. Toyota says that the recall remedy should be available to Tundra and LX600 owners in Q4 2024.
