Unwarranted Repair and Poor Service - Nissan Motus Centurion

I am writing to express my extreme dissatisfaction with the service I received from Nissan South Africa, specifically regarding an issue with my Nissan Magnite, and the handling of this issue by Nissan Motus Centurion.

On 18 April, while driving, the vehicle suddenly began to lose speed and displayed a series of critical error messages on the dashboard: "Check anti-pollution system," "Check Hill Start Assistance," and "Check ESC."

Given that the vehicle was nearing its next scheduled service (with approximately 1000 km remaining), I decided to take it to Nissan Motus Centurion for both the service and to diagnose the cause of these concerning errors.

Upon inspection, Nissan Motus Centurion identified the problem as a disconnected cable, stating that it was no longer connected to the harness. Shockingly, they informed me that this issue would not be covered under my warranty, claiming that the cable appeared to have been cut. They further stated that this alleged cut was the reason for the malfunction of the turbo and other related systems.

I find this explanation and the denial of warranty coverage completely unacceptable. I can assure Nissan South Africa that no one has opened or tampered with the vehicle at any point, except for when it has been taken in for its regular servicing at authorized Nissan dealerships.
