I have a 68 plate Sandero that has cut out twice at speed. First time it flashed up abs and service light and garage remapped ECU due to a fault on the injector wiring loom. Second time it has cut out completely driving at 50 mph showing no faults. Still under warrant the garage has had it for two weeks, unable to find the problem. They are trying to give it back to me but i have deemed it unsafe and so has Dacia. I am pending an investigation on the problem from Dacia. Has anyone else had this issue? please help.
