Advice STAY AWAY FROM HYUNDAI.

Why does Hyundai not have a spare vehicle to help their customers??? I bought a Hyundai Venu at Kempton Park brand new. I have so many problems with the car. The car did not even have 10 000 km and they changed the timing chain on the car in the first year and the ignition coils. It does have a clinking sound when the revs go over 2000r/min or when driven hard. They could not fix the problem at Hyundai garage at Boksburg. Now the car jerk again and backfire, and Hyundai want to test various parts on the car because they want to figure out what is the issue with the vehicle and now, they want to keep the vehicle for 2 to 3 days AND THE CUSTOMER HAVE TO RENT OUT OF HIS OWN POCKET A VEHICAL TO GO WORK WHILE IT IS STILL UNDER FACROTY WARTERY. If I did bump the car then i would get throught the ensurance a rent car, now hyundai make it my problem
