Instead of blaming on dealer or any other party Hyundai should take care of customer first.
Of course they must do the Root Cause Analysis to avoid reoccurrence of such incidence.
But here more focus needed on customer satisfaction and streamline of operations.
Hyundai must remember that happy customer is ambassador of their product.
I believe this is not the first time with Hyundai.
Hyundai has got decent reputation in our market but still, their processes are not healthy enough. I heard so many mischievous activities happen during the production line-up. One to mention is, during QA if some defects found, they don't mind it and just ship it. When it comes to exports to countries like Korea, They oblige the rules and QAs will be perfect. This is what i came to know from a friend who is working in Hyundai. Not sure how true this is.
