What Is the V35A-FTS Engine?

Toyota’s 3.5-liter twin-turbocharged V6 gasoline engine is the V35A-FTS. Toyota manufactured and launched it in 2017, and it powers several Toyota and Lexus flagships, such as:

• Toyota Land Cruiser 300
• Toyota Tundra (3rd Generation)
• Toyota Sequoia
• Lexus LX600

The engine was designed to succeed the old naturally aspirated V8s with the same (boosted) power in better gas mileage, lower emissions, and updated technology.

Common Turbocharger Issues with the V35A-FTS

The V35A-FTS is a high-torque, high-power, and long-lasting engine, but turbo engines are by nature more complicated in their design, making them more prone to failure in a variety of different ways.

Some of the typical turbo issues V35A-FTS owners and mechanics notice are explained below:

1. Turbo Lag or Lack of Power

One of the very first things you ever notice something is wrong is when you’re trying to floor it so you can accelerate and there’s just no power. Worse than usual turbo lag could be an indication of boost system or wastegate issues.

2. Turbo Oil Leaks

Turbos are also lubricated by oil. Oil leakage from ancillary seals or turbo housing is an issue, most likely due to dirty bearings or clogged oil lines.

3. Whine or Siren Noise

A whine on rising RPM is a dead turbo. Turbine blades or turbine bearings are probably the culprit.

4. Check Engine Light (CEL)

P0299 (underboost) or P0234 (overboost) codes are the most typical indications of turbo failure.

5. Exhaust Smoke

Blue or gray smoke out of the exhaust from oil burning in the combustion chamber when turbo oil seals are leaking and damaged.

Symptoms of Turbo Failure in V35A-FTS Engines

If any of this is happening, your turbo likely is on its deathbed:

• Slow acceleration
• Low or erratic reading on boost gauge
• Rattling or hissing sound in engine bay
• Excessive oil usage
• Worse fuel mileage
• CEL with turbo-related codes
• Excessive exhaust smoke

These problems usually end up ruining the engine if not properly fixed.

Why is Turbo Fail in the V35A-FTS?

The causes below are some of the reasons for turbo failure in this engine:

1. Oil Starvation

Dirty or low oil makes the turbo bearings seize and overheat. Use the right oil grade and follow the service intervals.

2. Foreign Object Damage

Anything sucked into the turbo (e.g., a blown air filter or intake hose trash, for example) will ruin the compressor wheel.

3. Boost Control Failure

Sticky or faulty weld on wastegate or boost solenoid will cause overboost or underboost, which will ruin the turbo and the engine.

4. Excessive Heat

Too-high exhaust gas temperatures, especially under hot running (aggressive driving), will ruin the turbo housing or internal components.

How to Diagnose V35A-FTS Turbo Trouble

Following is how to diagnose turbo trouble:

1. OBD-II Diagnosis

Scan for code including:

• P0299 – Underboost turbo
• P0234 – Overboost turbo
• P2262 – No turbo boost pressure received

2. Visual Inspection

Inspect for:

• Oil leak around turbo
• Intake or intercooler piping cracks
• Loosely connected or crimped hoses

3. Listen for Sounds

Listen for auto to whine, rattle, or hiss.

4. Boost Pressure Test

Boost gauge or professional tool can be used to test boost pressure under load.

Repair vs Replacement: When Do You Need a New Engine?

You might only need a turbo replacement or rebuild if:

• Engine compression is retained
• No damage internally
• Isolated failure of the turbo

But you might need to replace the entire engine if:

• Knocking or low compression is audible
• Oil contaminated intake and intercooler
• Crashed turbo debris destroyed the engine
• It would cost more to repair it than replace it
