The 2018 Vauxhall Insignia shows an overall defect rate of 116 per 100 vehicles, which is slightly better than the yearly average of 120 per 100 vehicles. Notably, the Insignia performs exceptionally well in steering, with a defect rate of just 0.27 per 100 compared to the average of 4.46, and also shows fewer issues in lights and electrics.
