Raipur news: In a first-of-its-kind ruling related to E20 ethanol-blended fuel, a consumer court has directed Maruti Suzuki India Limited and one of its authorised dealerships to either provide a new E20-compatible vehicle to a customer or refund the full purchase price of nearly Rs 20.5 lakh.

The order comes after the court concluded that the customer's vehicle was not compatible with E20 fuel, despite being sold at a time when India was promoting the use of 20% ethanol-blended petrol.

Court gives company 45 days to replace vehicle

The consumer forum directed Maruti Suzuki to deliver a new vehicle of the same model that is fully compatible with E20 fuel within 45 days. If the company fails to do so, it must refund the vehicle's purchase price of approximately Rs 20.5 lakh, along with registration charges, insurance costs and other related expenses. The court also awarded Rs 1 lakh as compensation for mental harassment and RS 10,000 towards litigation costs.

The verdict, delivered on July 14, 2026, is being viewed as India's first consumer compensation order involving alleged damage caused by E20 fuel.

Customer alleged wrong information at the time of sale

The complainant, Dr Premraj Debta, purchased a Maruti Suzuki Grand Vitara Strong Hybrid Zeta Plus from a Nexa dealership in June 2024.

According to the complaint, the dealer informed him that the vehicle had been manufactured in December 2023. However, records presented before the commission reportedly showed that the car was actually manufactured in January 2023. Since the doctor drives around 150 to 200 km daily, he chose the hybrid model for better fuel efficiency.

Engine trouble began within five months

The vehicle reportedly functioned normally initially. However, on November 11, 2024, an engine malfunction warning appeared on the dashboard and the car stopped working.

The dealership initially attributed the problem to contaminated fuel and emptied the fuel tank. During inspection, technicians allegedly found a white substance settled at the bottom of the tank.

Dr Debta subsequently lodged complaints with both the fuel station and the manufacturer. Testing of the fuel, however, reportedly found no issue with the petrol supplied. Despite multiple repairs, the vehicle continued to develop the same fault.

Company estimated Rs 5.3 lakh for engine replacement

According to the complaint, the company later acknowledged that the fuel tank had not been completely cleaned during the first repair and that chemically contaminated fuel had remained inside the system. Further inspections allegedly found white deposits and liquid residue in the fuel tank, fuel lines and filters.

The engine malfunction warning appeared again, the hybrid system stopped operating and the engine eventually became unusable.

Maruti Suzuki later informed the customer via email that the engine would need to be replaced at an estimated cost of Rs 5.3 lakh, which it said was not covered under warranty.

Although the vehicle was repaired and returned, it reportedly broke down again after travelling about 10 km following refuelling at the dealership itself. Another inspection allegedly found a curd-like white residue inside the fuel tank.

After the company declined the customer's request for a replacement vehicle or refund, the matter was taken to the consumer court in March 2025.

Laboratory report played a key role

Fuel samples were examined by SGS Laboratory, which confirmed the presence of ethanol in the petrol. According to the laboratory findings, the fuel met the E20 category. However, ethanol had separated from the petrol and settled at the bottom of the sample, reducing the effective ethanol concentration to around 6-7%.

Based on the evidence, the consumer forum concluded that the vehicle's engine was not suitable for E20 fuel despite being sold in a market where such fuel was being promoted.

Maruti Suzuki's position on E20 fuel

Responding to concerns over ethanol-blended fuel, Rahul Bharti, Senior Executive Officer, Corporate Affairs, Maruti Suzuki India, said the company has noted public concerns regarding the use of E20 fuel in older vehicles.

He clarified that cars manufactured and sold in India before 2023 were primarily designed for E10 fuel but, according to the company, have adequate safety margins to operate on E20 fuel without causing abnormal wear, corrosion, reduced vehicle life or damage to fuel-system components.

The court's ruling, however, was based on the specific facts and evidence presented in this individual case.
