Toyota had already issued recalls in May 2024 and again in November 2025 over the issue. The earlier 2024 recall also included Lexus LX SUVs that use the same powertrain.Kelley Blue Book noted that leftover machining debris inside certain engines can cause knocking, poor running conditions, no-start conditions, and loss of power.Toyota had previously said it added "additional controls" after the first two recalls to remove debris. Even so, the company now says those measures may not have fully resolved the problem.AdvertisementAdvertisement"We have found that, even after these additional controls, the remaining debris could be sufficient to cause damage to the No. 1 main bearing and lead to this issue," Toyota said.For people who rely on their trucks for commuting, hauling, job sites, or family transportation, this is more than a routine paperwork recall. Engine trouble can quickly turn into lost time, towing costs, and serious safety concerns.The latest expansion also raises questions about manufacturing oversight and whether Toyota moved quickly enough to fully contain the issue. After two earlier recall actions and added production controls, more vehicles are still being flagged for the same basic defect.Toyota said engines built after the affected batch received an improved bearing that should better resist any debris that remains. That suggests the automaker believes it has identified at least part of the weakness that allowed the contamination to cause severe damage.AdvertisementAdvertisementThe company has already repaired 77,000 of the 102,000 vehicles included in the original 2024 recall, so some progress has been made. Toyota is still developing fixes for trucks included in the late-2025 recall, as well as this newest recall expansion.If you're tired of frustrating maintenance problems with gas-powered vehicles, the lower upkeep costs that come with EV ownership may come as a surprise.While EVs can still face recalls from time to time, owners generally benefit from spending far less on routine maintenance and avoiding costly trips to the gas pump.Get TCD's free newsletters for easy tips, smart advice, and a chance to earn $5,000 toward home upgrades.
