Toyota recalls 100K Tundra trucks, Lexus LX SUVs over potential engine failure

Toyota will recall over 100,000 pickup trucks and Lexus SUVs in the U.S. over potential debris in the engine that could cause the vehicles to stall. According to the National Highway Traffic Safety Administration, the Toyota recall includes certain Tundra trucks and Lexus LXs built in 2022 and 2023 and equipped with the Japanese automaker's V35A six-cylinder engine.

According to NHTSA documents, debris that wasn't properly cleaned out during manufacturing may contaminate the engine and cause the main bearings to fail. Such failure is catastrophic to an engine. Toyota's own internal documentation provides a bit more detail:

"The subject vehicles are equipped with a specific V35A engine that contains crankshaft main bearings which allow the crankshaft to rotate within the engine assembly while running. During a specific production period, there is a possibility that engine machining debris of a particular size and amount may not have been cleared from the engine during manufacturing and subsequently contaminated the engine assembly during the production process. For these engines in the subject vehicles, the pressure on the main bearings due to the engine configuration is such that, if the aforementioned machining debris adheres to the bearings and operation of the engine continues at higher loads over time, failure of the bearings may occur."
