Renault Clio Fault - "Check Injection" Error at 5,700 km

I bought my Clio brand new from the authorized dealer in June 2025. After only 3 months and 5,700 km, I encountered the “check injection” fault. When I called the Renault complaint line, they offered no solution-oriented approach. I have been a Clio user for 5 years, and I experienced the same fault with my previous new car as well. Renault has worn me down psychologically, I had to go to the service countless times, missed work, was financially affected with fuel costs and kilometers, yet my grievances were never resolved. Now they are asking me to bring this car to the service again, but I am telling them to come and collect it. Instead, they say I should pay a valet fee. Once again, I am being victimized because of their faulty vehicles. When I said I would need to see a psychologist because Renault has ruined my nerves for 5 years, they replied that going to a psychologist would affect my work life. For 5 years, the cars produced by Renault have destroyed me. Shame on them—they sell defective cars and treat people as if they were fools.
