toyota s twin turbo tundra trouble just got bigger Toyota's twin-turbocharged 3.5-liter V6 recall just got bigger, and at this point, the automaker's explanation is starting to sound like a broken record to Tundra owners. Toyota announced the ongoing recall would once again grow this week, with an additional 44,000 Tundras built in 2024 added to the campaign, bringing the total number of affected trucks to almost 300,000 across multiple recalls. The issue hasn't changed-it's the same problem Toyota has been battling for more than a year-machining debris left inside the engine during manufacturing that can eventually destroy internal bearings and potentially lead to catastrophic engine failure. This latest recall affects a smaller batch of trucks from the previous two expansions. Toyota's original recall covered roughly 102,000 Tundras and Lexus LX SUVs built between 2022 and 2023. A second expansion later added another 127,000 vehicles. 10 Car Brands People Don't Want To Buy Ever Again toyota s twin turbo tundra trouble just got bigger Toyota says leftover debris inside the engine may damage the crankshaft's number 1 main bearing, which can trigger symptoms ranging from rough running and loss of power to complete engine failure or no-start conditions. In some cases, owners have reported engines locking up entirely. What makes the latest recall action concerning is that Toyota says the newly recalled batch are engines built using an updated manufacturing process that was supposed to prevent this problem. Toyota also says that "engines produced after those included in this recall were manufactured with an improved #1 main bearing to help resist certain debris that might remain." Which, speculatively, sounds like the Toyota may still be treating a symptom rather than a larger problem. toyota s twin turbo tundra trouble just got bigger The issue has become one of Toyota's largest quality-control headaches, particularly because the brand has built much of its reputation around durability and long-term dependability. The outgoing naturally aspirated V8-powered Tundra wasn't exactly known for exciting fuel economy, but owners never worried about catastrophic engine failures either. Toyota says it has already completed more than 77,000 recall repairs so far. Most fixes have involved replacing damaged internal components rather than entire engines, though some owners online have reported receiving full engine replacements depending on the severity of the failure. Affected owners will be notified once repairs become available through dealerships. Given the scale of the recall and the parts involved, however, some customers may end up waiting a while before their trucks can actually be fixed. 2027 Infiniti QX65: All the Details
