Is the Renault Symbioz Reliable?

As a brand-new model, long-term data is limited. However, early feedback suggests the Symbioz is solid in terms of build and hybrid performance. Most issues reported so far are minor, mainly involving sensors, electronics or software. These can often be addressed during servicing or under warranty.

How to Avoid Costly Repairs

  • Keep software up to date through Renault’s online update system
  • Regularly clean sensors and rear camera
  • Use the air conditioning even in winter to maintain system pressure
  • Check all doors, boot and infotainment functions during test drives
  • Book full inspections during annual services
