Toyota’s V6 Engine Troubles Persist: Replacement Units Failing Early in 2026

Toyota’s V35A-FTS twin-turbo V6 replacement engines are failing again, even after the company issued a recall in 2024. A 2026 replacement engine installed in a Tundra with only 64,000 miles showed severe main bearing wear, suggesting the underlying problem persists. The repeated failures are eroding owner trust and raising questions about whether Toyota has truly solved the issue.

The V6 replacement problem timeline

Toyota introduced the V35A-FTS twin-turbo V6 in 2022 Tundra models to replace the larger V8 engine. The new engine promised better fuel economy and competitive power. In 2024, Toyota recalled the engine after discovering machining debris left inside during assembly was causing catastrophic failures. Now, replacement units installed in 2026 are showing the same wear patterns, suggesting the manufacturing issue may not be fully resolved.

What the latest teardown revealed

A YouTube channel called I Do Cars tore down a 2026 replacement V6 engine from a Tundra that had only 64,000 miles on it. The engine’s third main bearing on the crankshaft showed significant damage, and rod bearings displayed varying amounts of wear. The teardown found metallic debris inside, but it remains unclear whether the debris caused the bearing failure or resulted from it. This is a practically new engine, making the damage alarming.

Owners face mounting warranty and resale concerns

Some Tundra owners report receiving replacement engines that have already failed, forcing them into a second or third engine swap. One owner documented two engine failures and questioned whether a third replacement would damage resale value. Multiple engines on the Carfax report could deter buyers and reduce trade-in value, leaving owners with limited recourse if the replacement engine fails outside warranty.

Toyota’s stock and investor implications

Toyota (TM) is rated B+ by Meyka with a 12-month price forecast of $212.10, up 7% from the current $198.20 level. The company’s PE ratio of 8.74 is attractive, but persistent engine recalls could damage brand reputation and increase warranty costs. With earnings due November 4, 2026, investors should watch for management commentary on the V6 engine issue and any expanded recall scope.

Final Thoughts

Toyota’s V6 engine troubles threaten both owner loyalty and the company’s cost structure. With Meyka grading TM a B+ and forecasting $212.10 by year-end, the stock remains relatively cheap, but unresolved engine defects could weigh on long-term margins and brand equity.
