Engine Seized after 1500 miles? DACIA Duster II (10.2017 - ...)

Hi I have a 5 month old Dacia Duster 2 MY23 1.3 petrol with 1500 miles on the clock. Since I’ve had the car it’s run perfectly.

Until yesterday when I stopped at traffic lights. The car would not start. The words Stop Start appeared on the dashboard followed by Brakes. The car would not start. Just a clicking noise and the engine not turning over. I could also smell a slight chemical smell inside the car.

The electrics still worked, radio, lights, windows.

RAC Breakdown attended and he rolled the car along the road thinking he could jump start as it was maybe a starting motor issue but there was no reaction. He then checked the dipstick and there was plenty oil but then rocked the car back and forward and pointed to something and said it should move, which it didn’t and then told me the engine was seized!

The car was towed to the dealership and it’ll be 6 weeks before they can examine it!!

Anyone have thoughts on the guy’s prognosis for such a new car and engine?

Any thoughts appreciated especially as I won’t habe anything comfirmed for at least 6 weeks.
