Parts availability issue with Sorento

I own 2 Kia Sorentos (2013 and 2016 models). They are absolutely fantastic vehicles to drive - comfortable, plenty of great features and value for money. But.... parts availability is proving to be its downfall. I have had cause to replace the rear window and was told the part had to come from Korea. It took 10 days to get a window replaced, and that after some helpful people at Kia SA assisted in rushing things. Now I have had a boot unlocked for nearly 2 weeks due to unavailability of a replacement lock for the boot. Again, waiting for parts from Korea. While I love the car, I cannot recommend this vehicle to others until Kia SA get their act together with regard to after sales service regarding availability of parts. It is a deal breaker for me when I come to renew vehicles.
