| Description of the problem | This began as a intermittent hesitant clunk, both during acceleration/deceleration in transitioning between electric motor / gas engine. It has progressed into an unexpected physical jump while going forward and reverse. The latest development was lurching forward at a crosswalk without consciously stepping firmly on the brake. Emails have been sent to hyundai without a response addressing the problem. The car has been into the dealership twice, where components unrelated to the symptoms were replaced and a manager saying "that's what they do, and hyundai considers it normal". Normal !?!? The problem is widely known, because it has been published in the media, and no dealership will offer anything but a lowball offer on a trade in, just to turn it around and dump it to auction for parts. |
