Problems with my Jeep Renegade

After completing only 34 000 km's in my 2019 Jeep Renegade 1.4, I was informed I had to replace my turbo at a cost of +/- R24 000! There was NO EVIDENCE to suggest this was necessary (car was performing 100%) but there was a "diagnostic warning" which was unable to be remedied by the agents technicians. It would NOT go away until a new turbo was installed. I had the old turbo independently tested and it was found to be working 100%. In the end, I was assisted with some discount... but this said, I still had to pay R10 000! I don't believe this was my problem, I do believe there is a latent defect in this product. The real ugly part was that, despite polite requests for attention to my claim on this matter (some being three months old) I am getting NO RESPONSE from either Stellantis (Jeep SA) or their local agent. I have now been forced to go to the MIOSA (onbudsman) in the hope of a fair outcome. Yes, the warranty was over but a turbo at this low mileage, should never have become an issue.
