An Indian court has ordered Maruti Suzuki to replace a vehicle damaged by E20 fuel, marking the first judicial ruling to hold an automaker liable for engine issues linked to the country's ethanol-blended petrol program.

The decision represents a significant legal development for India's automotive sector, which has faced mounting pressure over the safety and compatibility of the 20% ethanol blend mandated by the government.

The ruling could expose automakers to greater liability as consumers increasingly seek redress for engine failures attributed to the fuel mix.

While the Indian Petroleum Ministry has previously dismissed widespread social media claims of engine damage as misinformation, this court order provides a concrete legal precedent that may encourage further litigation.

The verdict underscores the tension between the government's push to reduce crude oil imports and cut emissions through the E20 program and the practical challenges faced by vehicle manufacturers and owners.

Political opposition to the mandate has also intensified, with Arvind Kejriwal, national convenor of the Aam Aadmi Party, formally demanding clarification on liability from major automotive manufacturers.
