My 2017 Hyundai Santa Fe had a new engine installed at the dealership, Fred Beans Hyundai Flemington, NJ. I picked it up on [XXX] on [XXX] (and after 134 miles) my car's check engine light came on. I rerouted to dealership about 8 miles. Sitting outside service bay, I smelled smoke and then saw smoke coming out of vents. I then jumped out of car and the car became engulfed in flames and subsequently exploded. The day I picked it up, I pointed out to the service manager that they had not reattached everything to the car properly, sloppy workmanship. Best guess is that they did not attach a valve correctly.
