The transmission's solenoid failure signal may fail to reach the engine control unit, causing the gearbox to over-rev in certain gears.
No incidents have been reported in India so far, and the fix is a straightforward software update carried out free of charge.

A Gearbox Glitch in Two Flagship SUVs

969 Land Cruisers and 117 Lexus LX Units Are Affected

Toyota Kirloskar Motor and Lexus India have jointly announced a voluntary recall for a combined total of 1,086 vehicles in India. The recall covers 969 units of the Toyota Land Cruiser 300 built between September 4, 2024, and September 30, 2025, along with 117 units of the Lexus LX produced between March 6, 2025, and September 29, 2025. The recall was officially announced on February 18, 2026.

Both of these SUVs are platform siblings, built on Toyota's TNGA-F body-on-frame architecture and powered by the same 3.3-litre twin-turbocharged V6 diesel engine producing 304 hp and 700 Nm of torque, paired with a 10-speed torque-converter automatic gearbox. It is this very gearbox that sits at the heart of the issue.

What Is Actually Going Wrong Under the Bonnet?

The Problem Lies with the Gearbox's Electronic Brain

The 10-speed automatic transmission relies on a set of linear solenoids to regulate and execute gear changes. If one of these solenoids were to fail under certain driving conditions, the transmission's control unit may not properly communicate that failure to the engine's ECU (Electronic Control Unit). Because the software is not equipped to suppress the resulting fault, the transmission can begin over-revving in certain gears.

The consequences of this are layered and potentially serious. At higher speeds, the driver may notice a sudden and disconcerting drop in power to the driven wheels. Over time, the over-revving can cause internal damage to the gearbox itself.

In more extreme cases, a damaged transmission housing could allow gearbox fluid to leak onto hot exhaust components, raising the risk of a fire. This is not a mechanical defect in the hardware but a lapse in how the software responds to a hardware failure, the kind of issue that is increasingly common as modern vehicles become ever more software-dependent.

Importantly, Toyota and Lexus have confirmed that no such incidents have been reported in India to date, and the recall is entirely precautionary in nature.

A Global Issue, Not Just an Indian One

The US Market Is Also Seeing This Recall

This recall extends well beyond India. In the United States, Toyota has issued recall number 26LA01 covering 4,374 units of the 2025–2026 Lexus LX 600 fitted with the same Aisin-sourced 10-speed automatic.

American owners are to be notified by post in April 2026 and directed to their nearest Lexus dealership for a software update, also free of charge.

What Is the Fix, and What Should You Do?

It's a Software Update, So Think of It as a Patch for Your SUV

The good news is that because this is a software-side problem, there is no need to replace any physical components. Dealerships for both Toyota and Lexus will simply reprogram the transmission control computer and the engine ECU to ensure the two systems communicate correctly in the event of a solenoid failure. The update ensures the system can detect the fault and suppress any dangerous over-revving.

Owners of affected vehicles will be contacted directly by their respective dealerships. However, if you own a Land Cruiser 300 or Lexus LX that falls within the relevant production dates, you can also proactively reach out to your nearest authorised service centre. The fix is completely free of cost, and given what's at stake, there is no reason to delay.
