Is it common with the 2020 sonata to have blower motor issues?

Hi this is Dusty, I'm one of the auto experts on RepairPal's Car Genius team. That's sounds miserable, no cool air movement (or hot if it's that time of year) is uncomfortable. As far as the frequency of that specific repair, I can't say. It does seem peculiar to me, but at the end of the day blower motors, window motors, etc. are just fancy light bulbs. And I think at one point we've all walked into a room as a bulb blew randomly. It's worth having a dialogue with your preferred Hyundai dealership about the issue, let them know you're concerned about the longevity of the repair, and future repeat repairs. If you have any other questions feel free to give us a call at 877-913-1554! We'll be happy to help or find you a certified shop in your area!
