I stopped by the dealer today, had a right rear rattle confirmed (it has been annoying me since April), and an appointment next week. Dealer didn't know of an issue with Niros, but did say it is known problem with Sorrentos. Wouldn't be surprising to find out that it is the same shock. Plastic dust cover top of shock is prime suspect as earlier discussed. Let you know next week what they will do.but will definitely mention it to the dealer when it goes in, just to see if it is a known thing!
