Unhappy customer

I am a owner of an isuzu DMAX fleetside that I bought in 2019 of which the vehicle started giving problems at 11000km. It had many factory faults and their customer services are very poor and disappointing, they don't take matters serious as even today the vehicle is by them for inspections.It is at +-71000km now. The matter affects me as the vehicle I used it for business and family affections as it is my daily usage, at this point I'm just provided a certesy car for only seven days. I am also worried when its out of warranty and this happening how will I manage the costs as I pay the installment every month but nothing is being considered. I have been patient for nearly 3years now, as( I do not want the vehicle anymore) as they said it has electrical error. So now I am much afraid of the car as it could catch fire. the first one nearly killed me as it took out the complete wheel hub while driving it. This one was a replacement done by my insurance as isuzu failed to replace me with the other. I am very disappointed by ISUZU Motors
