Toyota T24A-FTS
2.4 L · inline-4 · turbocharged · petrol · 2021–present
Also known as: t24a-fts, t24a, 2.4 turbo toyota, hybrid max, nx 350 engine, t24a-fbs
Toyota's 2.4-litre turbocharged four, and the engine that replaced the naturally aspirated V6 across much of the range — the Lexus NX 350 and TX, the Highlander, Grand Highlander and Crown.
The version to identify first is Hybrid MAX, which pairs this engine with an electric rear axle and a much more aggressive control strategy than Toyota's usual hybrids. A driveability complaint on a Hybrid MAX car is a question about the hybrid system before it is a question about the engine, and a procedure written for the plain turbo does not describe it.
Do not carry over what has been written about the V35A twin-turbo V6. That is a different engine with its own well-publicised programme, and the two are easy to conflate because they arrived together and replaced the same V6s.
Being recent, its long-term failure patterns are not established, which is worth stating rather than filling with speculation. The systems generating faults so far are the ones carrying the most sensors — the turbocharger's control circuit, the emissions equipment, and on Hybrid MAX cars the interaction between engine control and the hybrid strategy.

Information, not instruction
CarGeek is a reference, not a service manual. Its pages are written from public sources and from what other people have found, never from a manufacturer's own service information, so they can be wrong or incomplete for your particular vehicle. Some of what they describe carries real risk: high voltage, fuel under pressure, stored energy, hot and moving parts.
Have anything you intend to act on checked by a trained person against the manufacturer's own procedure for your vehicle. Nothing here replaces that procedure.

What makes one worth reading:
- The car — make, model, year and engine. The same fault behaves differently on each.
- What you measured, not only what you replaced.
- What actually fixed it — or that nothing did, which is worth knowing too.
