Scenic 3 1.2 tce 130 from 2015 with 52000kms
Motorhousing on motorway without any prior warning except the final warning "risk of engine failure"
Renault announces me the engine break almost laughing.
Known design problem but partial support with 2800 euros at my expense.
The spare engine already shows warning signs that are not reassuring.
Lamentable from such a big brand
