Complaint against Nissan SA and Motus Nissan East Rand

The complaints about the two Magnite vehicles have been dragging on since we bought these vehicles and for close to two years now we have been communicating with Nissan SA without the problems being resolved. We are no longer even being afforded the courtesy of an acknowledgement or a response from their office. We have taken the two vehicles to Motus Nissan East Rand numerous times and the faults are not resolved. The brake system on these vehicles is a huge safety concern. It was discussed with the service manager at Motus East Rand who indicated that tge matter of concern was escalated to Nissan SA.Besides being noisy, it often happens that sometimes the vehicles don't have breaks when needed. The radios often just goes blank whilst driving. This causes huge problems when you are using maps in an unknown area. It has also happened that the engine of KM 62PVGP cuts out whilst driving out of Kempton Park and getting onto the highway next to OR Tambo Airport late at night. This is a serious concern and a risk to my family’s safety on our roads. The other Magnite KM75DZGP makes a noise when turning the steering wheel whilst driving and this was reported numerous times to the Motus Service Manager and to Nondi Sibeko st Nissan SA. It is clear that they only want to sell vehicles, but do not want to support their clients and resolve issues on vehicles sold by them.
