We had brought the vehicle in as the engine light was on we were told there was an update which was completed and the light was off. The next day the light came on again we had to bring it back and we don't live in Calgary so this was frustrating we were then asked if it was put on a diagnostic we said we assumed as how else would they have discovered the issue then we were told if we didn't ask for it they wouldn't have done it as it is an extra cost and wouldn't have done it without consent then it was we assume put on the diagnostic that day as they then discovered it needed a new thermostat.
