Confusion in Dacia Duster Service Responses and Unresolved Warnings

My 2015 Dacia Duster was involved in a collision, and the ESP (Electronic Stability Program), engine mechanical fault warning, and general fault warning lights on the instrument panel all turned red. I was in Varna, Bulgaria, and the car drove about 150 kilometers to the Dacia service center. It was a Friday, and the service said I couldn't use the car in that condition and asked me to return it the following day. However, the service was closed on Saturday, leaving me in a bind. I decided to drive the car back to Turkey, a distance of 550 kilometers. Surprisingly, after refueling near Corlu, all of the warning lights on the car went out, and it resumed normal operation. I took the car to Dacia service on July 24, 2023, and the customer representative scheduled an appointment for July 31, 2023, stating that they couldn't check it right away. When asked if it was safe to drive until "motor stop" appeared, they said it was. However, the car's owner's manual specifically stated that it should not be used in such a condition. Several questions are raised by the findings: How did the car manage to travel 550 kilometers while the warning lights were illuminated? What caused the warning lights to turn off by themselves? Why isn't "motor stop" mentioned in the car's owner's manual? What accounts for the disparity between the service's response and the manual's recommendation? I wish Dacia provided better after-sales support - one that is relevant, serious, logical, consistent, and dependable.
