Worst service

Hi all, I purchased Hyundai xcent 1.1 CRDI on 2015 and I have driven 78,000 km now.Performance was good till 40,000km and after my service at 40k,started series of issues and I visited service centre many times after that for different issues. The main issue Iam still facing is Engine sound during cold start(in morning) and it lasts upto 1 minute.This happened after changing driving belt at 40,000km service. I said this complaint to my service centre and after series of inspection they changed something the length of notice is reduced and and they convinced me that this small sound is usual for xcent. Still Iam driving with same noise and no solution from service centre. Also my break sensors damaged twice,Heater got damaged,Poor engine performance If you have lot of time to spent in service centre,then you can go with this car. Note : I faced all this issue after servicing my car on-time regularly. positives are perfect handling Interior Music system, If a good service centre is available in your area,then you can go with this car.
