Brand-New Renault Duster Breaks Down Twice and Dealer Refuses Replacement

On December 30, 2025, we purchased a Renault Duster with license plate 48 AZS 162 in the name of F***** S**** U**** through Bodrum Kutay, making the payment there and taking delivery of the vehicle in Muğla.

In less than a month and a half, while driving and without any prior issues, the check engine light and multiple warning indicators suddenly came on. The engine went into protection mode, the vehicle stopped, and it would not respond to the gas pedal. I took the car to an authorized service center on February 9, 2026. Three days later, I was told there was nothing wrong with the vehicle and that I should come pick it up. However, the technicians at the service center had personally seen the warning lights and the malfunctioning condition of the car. Despite this, I was forced to take the vehicle back.

Not even ten days later, while driving in traffic, the car again failed to accelerate even though I pressed the gas pedal, and it would not go faster than 30 km/h. This time, in addition to the previous warning lights, the transmission malfunction light came on, and the vehicle began giving audible warning signals. I recorded multiple videos and took the car back to the service center for the same issue.

My vehicle has now been sitting at the service center for approximately 12 days. For the first week, I received no proper updates from the sales manager, technical service, or service manager, and my calls were not returned. Only after I stated that I would file complaints with the Consumer Arbitration Committee and Renault France did the service manager contact me.

Last week, they finally acknowledged that the vehicle has a defect. They told me that a control unit (engine computer) would be sent from France and replaced. However, they also said that although there is a problem with the vehicle, they have not been able to fully diagnose it, and even if the computer is replaced, they cannot guarantee that the same issues—or other related problems—will not happen again. In other words, they told me I would have to keep using the vehicle to see whether the problem returns, as if this were some kind of trial period.

I paid $60,207 for this brand-new vehicle, and I do not want to live with constant uncertainty or the fear that it may break down again at any moment. Although the car is still under factory warranty and they say the repairs are covered, experiencing such a serious malfunction twice in a short period of time, being told the first time that “nothing is wrong,” and then being informed that the issues could reoccur has completely destroyed my trust in this vehicle.

I no longer want to use this car under any circumstances. My demand from the brand, in accordance with my legal rights, is a full replacement with a brand-new vehicle. I do not want this car repaired and returned to me. I expect it to be replaced with a new, defect-free vehicle and for my complaint to be resolved immediately.
