Recall Date: 5/20/2026
NHTSA ID: 26V320
MFr. Campaign Number: 25TB14 / 25TA14
Manufacturer: Toyota Motor Engineering & Manufacturing
Affected Components: V35A Engine Short Block Assembly (#1 Main Bearing)
Potential Number of Units Affected: ~43,566
Which Toyota vehicles are affected?
The recall covers 2024 Toyota Tundra pickups equipped with a specific V35A engine configuration, manufactured at Toyota Motor Manufacturing Alabama (TMMAL) between February 7, 2024, and August 5, 2024.
This is the third recall in a sequence involving the V35A engine. The same engines produced before this window were recalled under 24V-381 and 25V-767. Other V35A engines were produced with an improved main bearing, and Toyota continues to monitor the effectiveness of that improvement. Other Toyota and Lexus vehicles are not equipped with a V35A engine of this configuration.
Toyota states it is unable to estimate the percentage of involved vehicles that actually contain the defect — the 1% figure in the NHTSA portal reflects the system's required integer entry, not a confirmed prevalence rate.
What drivers need to know
The defect is a manufacturing issue with the crankshaft main bearings inside the V35A engine. During a specific production period, machining debris of a particular size and amount may not have been fully cleared from the engine during assembly. That debris can contaminate the engine and adhere to a main bearing. Over time, with continued operation at higher loads, bearing failure can occur.
Bearing failure can lead to engine knocking, rough running, no-start conditions, or an engine stall. An engine stall while driving causes a loss of motive power — and at highway speeds, that loss of motive power can lead to a crash.
The remedy is still under development as of the recall filing. All known owners of the subject vehicles will be informed that they will be contacted when further information about the remedy is available. Dealer notification was issued on May 20, 2026, with owner notification scheduled between July 6 and July 20, 2026. Toyota used its general reimbursement plan on file for owners who have already paid out of pocket for related repairs.
Toyota recall background
This investigation has been running for more than a year and crosses multiple recall campaigns. When Toyota filed recall 25V-767 in November 2025, the company continued to investigate certain V35A engines produced at TMMAL after the 25V-767 cutoff — engines built with improved manufacturing processes and other changes, including a cam housing clearance change. Toyota and its supplier collected both non-failed engines and engines with alleged #1 main bearing failures, tore them down, and analyzed the bearings.
In February 2026, Toyota found a stack-up of bearing pressure based on variables including timing chain tension and engine loading, but the pressure stack-up could not differentiate engines from the new study period from those previously recalled. From March through May 2026, the team performed bench testing on #1 main bearings without prior wear, applying specified pressure to simulate engine loading while introducing debris representative of what was found in field engines. Bench testing showed that once a piece of debris of sufficient size is introduced onto the bearing, additional pieces don't significantly change the fatigue strength outcome.
By early May 2026, engine collection, teardown, and bearing analysis confirmed that bearings produced during the study period showed the same wear pattern observed on bearings from the 24V-381 and 25V-767 recall populations. On May 14, 2026, Toyota decided to conduct a voluntary safety recall. As of May 13, 2026, Toyota was aware of 30 Field Technical Reports and 360 warranty claims related to the condition.

How BizzyCar can help
Tundra is a work truck. Owners are commercial buyers, fleet operators, and high-utilization personal-use customers who keep their vehicles on the road rather than on a fixed service cadence. The remedy is also still under development, which means dealers will need to communicate twice — once with the initial owner notification in July, and again when the remedy is ready. That extended window is where the response rate erodes fastest.
BizzyCar's Recall Outreach product identifies affected vehicles in a dealer's customer database and initiates automated two-way SMS outreach. For Toyota dealers, that means staying connected to Tundra owners across the gap between notification and remedy — and being the first call when the fix is available. Book a demo.
