Genoeg gesukkel

I reported the automatic brake system when taking my X trail 2 liter 2016 model for service but they didnt fix it , I almost lost my family wife and kids, the brakes jam right in the middle of the road luckily I wasnt driving fast. Nissan cant get away with this I only have this xtrail for 4 months Nissan Bloemfontein just give me my key without any proof what they have done on the car without any word. The car has a winding sound like a diff sound after reporting this i was just said there is nothing we can do about that. And Nissan knew that the xtrails is having that problem but doing nothing.
