Ongoing issue with brand new Renault Duster 1.6 expression since 1st month of purchase

We bought a BRAND NEW Renault Duster in October 2016 from Renault Brackenfell for peace of mind. Within the 1st month of purchase, the vehicles rev counter started surging and experience a loss of power. This continued and got SO BAD that the engine light came on and the car completely stopped in traffic and had to hoisted to the nearest service centre. To date the vehicle has been in to their service centre 9 times for the same problem!

Renault SA replaced the fuel pump, throttle body and plugs, yet the issue persists. It is clear that Renault SA has NO CLUE what the issue is and have now decided to completely ignore us. The case was logged with the Ombud and they had 10 days to respond, to no avail. And the problem continues.

This is such a total disappointment in such a HUGE brand. Escalating to senior management does not help at all.

Can we once and for all put this issue to bed so we can get on with our lives!
