Res Ipsa Loquitur | Repeated Engine Seizure Proves Manufacturing Defect, No Expert Report Needed: UP State Consumer Commission - 2025-08-05

Repeated Engine Seizure is Proof of Manufacturing Defect, No Expert Opinion Required: UP Consumer Commission Upholds Refund Order for Renault Duster

LUCKNOW: The Uttar Pradesh State Consumer Disputes Redressal Commission, in a significant ruling, has held that a car engine seizing twice, including shortly after a replacement, is self-evident proof of a manufacturing defect under the principle of res ipsa loquitur (the thing speaks for itself). The Commission affirmed that in such clear-cut cases, the consumer is not required to produce an expert report to prove their claim.

The bench, comprising Hon'ble Mr. Sushil Kumar, Officiating President, and Hon'ble Mrs. Sudha Upadhyay, Member , partially allowed appeals filed by Renault India Pvt. Ltd. and its dealer, M/S Karan Ashok Vehicles Pvt. Ltd. The Commission upheld the District Forum's order directing a refund for the faulty vehicle but reduced the interest rate from 9% to 6% per annum.

Background of the Case

The complaint was filed by Deep Arora and his mother after the passing of his father, the original owner of a Renault Duster purchased in May 2014. The vehicle's engine first seized in February 2016 at approximately 69,000 kilometers. The company repaired the engine and replaced the turbocharger under warranty.

However, merely 7,000 kilometers after the repair, the engine seized again in July 2016. The vehicle was returned to the service center, where the company agreed to replace the entire engine. A dispute arose when the manufacturer and dealer refused to provide a fresh warranty for the newly installed engine, leading the consumer to refuse delivery of the car.

The District Consumer Commission, Moradabad, had ruled in favour of the consumer, finding a clear manufacturing defect. It ordered the appellants to refund the car's price of ₹10,45,665 (after a 20% depreciation for two years of use) along with 9% annual interest.

Arguments from Both Sides

Appellants' Contentions (Renault India & Dealer):

* The primary argument was the absence of an expert report to technically establish a manufacturing defect, which they claimed was mandatory.

* They alleged that the consumer had missed the first and fifth scheduled services, potentially contributing to the engine failure.

* They cited several judgments from the National Consumer Disputes Redressal Commission (NCDRC) to argue that a manufacturing defect cannot be presumed without expert evidence.

Respondent's Contentions (The Consumer):

* The consumer's counsel argued that the fact the engine seized not once, but twice, was conclusive proof of an inherent defect.

* They contended that the replacement of the first engine under warranty was an admission of a defect by the company. The failure of the second engine so soon after installation further solidified this claim.

* The consumer also alleged that the service center had deleted the car's service history from their system to create a false narrative of missed services.

Commission's Analysis and Ruling

The State Commission decisively rejected the appellants' arguments, emphasizing the application of res ipsa loquitur .

The Commission observed, "The seizure of the vehicle's engine twice is sufficient to apply the principle of 'the event speaks for itself'. It does not require any expert evidence to be produced for this."

The bench reasoned that the warranty for the newly installed engine should commence from the date of its installation, not from the original purchase date of the vehicle. Since the second engine failed in July 2016, shortly after being installed, it was well within the warranty period.

The Commission distinguished the precedents cited by the appellants, stating that the facts of the current case were self-evident and did not require the same level of technical proof as other cases. The repeated failure was deemed undeniable proof of a fundamental manufacturing flaw.

Final Order

While largely agreeing with the District Commission's findings on the manufacturing defect, the State Commission modified the final order slightly.

• The appeals (Appeal No. 106/2023 and Appeal No. 811/2022) were partially allowed.
• The order to refund the depreciated value of the car was upheld.
• The interest payable on the refund amount was reduced from 9% to 6% per annum .
• The remainder of the District Commission's judgment was confirmed.

The decision reinforces a crucial pro-consumer principle: where a product's failure is so blatant and repetitive, the burden of proving a manufacturing defect through complex expert reports can be waived.
