Well, there are many, many surveys like this.
I have a surprise for you: according to 9 European consumer organizations and 50,000 respondents, this is how they published the 10 most and 10 least reliable car brands:

The Dutch Consumers' Association conducts annual research into car defects together with nine other European consumer organizations. In total, the distributed 2025 questionnaire was completed by more than 50,000 Europeans. It concerns cars no older than ten years. The questions focus on problems that occurred with the car in the past year (2025). In this latest study, breakdown statistics for some 300 different models from 39 car brands have been mapped out.
If a repair could wait, that accounts for 20% of the rating. If the car had to go to the garage immediately, that counts for 35%, and for 45% if the car could no longer drive. All results have been aggregated per brand and model.
The results were adjusted for age and mileage. In addition, overall satisfaction with the car was assessed.
