 I purchased a Sonata Hybrid Limited in April of 2013.  About a year later, it seemed that an occasional panic stop would cause the car to stop abruptly rather than pulse to a safe stop.   After noticing that it seemed to do that each of the few times that I applied the brakes in that manner, I took the car to the dealer, asking them to also check the brakes for a banging noise occurring each time the brakes were applied when coming to a stop sign/light.
 Many months and service calls later, my VA Lemon Law attorney suggested that I might want to avoid Hyundai or Kia if I ever expected to have my interests considered.  I traded in that piece of @)$(*^* as quickly as I could!
