Toyota 3.4L i-FORCE twin-turbo V6 (V35A-FTS): years, specs & known problems

By CarWhere Research · Updated

The V35A-FTS is the 3,445 cc twin-turbocharged V6 Toyota calls i-FORCE. It replaced the 5.7L V8 in the 2022 Tundra, rated at 389 hp and 479 lb-ft (348 hp and 405 lb-ft on the SR). The gas-only version has been recalled three times for machining debris that can damage the #1 main bearing.

Toyota introduced the twin-turbo V6 with the third-generation 2022 Tundra. It has an aluminum block, an 85.5 × 100 mm bore and stroke, chain-driven double overhead cams with 24 valves, dual VVT-i and a water-cooled intercooler, and it is paired with a 10-speed automatic. EPA listings describe it as combining direct and port injection. Toyota markets the displacement as 3.5L in early releases and 3.4L in the EPA listing; both describe the same 3,445 cc engine.

Standard tuning is 389 hp and 479 lb-ft; SR grades use a lower tune of 348 hp and 405 lb-ft. A TRD Performance Package, offered from early 2024, raises the standard engine to 421 hp. The same V6 is the gasoline half of the i-FORCE MAX hybrid in the Tundra and Sequoia, covered on its own page. The defining ownership issue is the machining-debris recall series for gas-only Tundras, which Toyota has addressed with replacement engines built with an improved #1 main bearing.

3.4L i-FORCE twin-turbo V6 (V35A-FTS) problems and what to check

Machining debris and #1 main bearing damage (gas Tundra) (2022–2024)

Major repair

Toyota found that machining debris may not have been fully cleared from some engines during production. The debris can damage the #1 crankshaft main bearing, leading to knocking, rough running, a no-start or a loss of power. Toyota has filed three related recalls: May 2024 (about 102,000 US vehicles), November 2025 (2022–2024 Tundra plus Lexus LX and GX, about 127,000 gas-only vehicles) and May 2026 (2024 Tundra, about 44,000). The hybrid i-FORCE MAX is not included.[8][9][10][11][12]

Symptoms

  • Engine knocking from the bottom end
  • Rough running or stalling
  • Engine will not start
  • Loss of motive power while driving

Check before buying

  • Run the VIN at Toyota.com/recall or nhtsa.gov/recalls for all three debris campaigns
  • Ask for paperwork showing whether a replacement engine was installed and when
  • On a 2024 truck, confirm the status of both the November 2025 and May 2026 campaigns

Program: Toyota safety recalls (May 2024, November 2025, May 2026); remedy is a free repair at Toyota dealers, with replacement engines built using an improved #1 main bearing

Frequently asked questions

Is the Toyota 3.4 twin-turbo the same as the 3.5L in Tundra press releases?

Yes. Toyota's 2022 launch releases call it a 3.5-liter, while the EPA listing and later materials say 3.4L. The owner's manual gives the actual figure: 3,445 cc from an 85.5 × 100 mm bore and stroke, engine code V35A-FTS.

How much horsepower does the Tundra twin-turbo V6 make?

Toyota rates the standard i-FORCE V6 at 389 hp and 479 lb-ft. SR grades use a lower tune of 348 hp and 405 lb-ft. The TRD Performance Package, offered from early 2024, raises output to 421 hp, with peak torque arriving at 2,000 rpm.

Which Tundras are in the engine debris recall?

Toyota has filed three related recalls covering gas-only Tundras: one in May 2024 (about 102,000 US vehicles), one in November 2025 covering 2022–2024 Tundras (about 127,000 Toyota and Lexus vehicles) and one in May 2026 covering about 44,000 2024 Tundras.

What does the debris recall fix involve?

Toyota says dealers have repaired more than 77,000 of the trucks in the first recall with engines built using an improved #1 main bearing. For the November 2025 and May 2026 recalls, Toyota said it would contact owners in phases as the remedy became available. The repair is free.

Is the i-FORCE MAX hybrid affected by the debris recall?

No. Toyota's November 2025 announcement says the recall covers conventional gas models only, and the May 2026 recall covers 2024 Tundra non-hybrid vehicles. The i-FORCE MAX hybrid uses the same V6 family but is not part of these campaigns.
