Customer Care is REF 5162

After the complaint the car was taken in and repaired, but 3 weeks later the same noise is back. On the 15000km service a diagnostic was done, but did not reveal any fault. On a later day, the service manager was taken and he heard the noise. Now the car needs to be booked again. Like I mentioned in the previous complaint, we paid over R300k for the car, which is clearly a so called dud. How often does it still need to be fixed and what happens after the guarantee expires? I think the car needs to be replaced!!
