I PURCHASED THIS KIA BRAND NEW IN 2008. HAD TO TAKE IT TO THE DEALERSHIP 3 TIMES WITHIN THE FIRST 6 MONTHS BECAUSE WHEN I REACHED BETWEEN 40 AND 50MPH THE VEHICLE JERKED. WAS TOLD EACH TIME THERE IS NOTHING WRONG. ON THE FINAL TIME THE SERVICE MANAGER RODE WITH ME AND TOLD ME IT WAS THE WAY I DROVE. I HAVE NOW HAD THIS VEHICLE FOR 3 AND HALF YEARS. IT HAS 67,000 MILES. I AM STILL HAVING THE JERKING ISSUE AND NOW THE ENTIRE REAR DIFFERENTIAL NEEDS TO BE REPLACED. I HAVE RESEARCHED DIFFERENT FORUMS ON DIFFERENT WEBSITES AND HAVE FOUND THAT THIS SEEMS TO BE AN ISSUE FOR A LOT OF KIA SORENTO OWNERS. THE DEALERSHIP WILL NOT HONOR MY WARRANTY BECAUSE I DID NOT HAVE THE SERVICE DONE AT AUTHORIZED KIA SERVICE ESTABLISHMENT SO I HAD TO OUT OF POCKET PAY $1100 TO HAVE MY 3 AND HALF YEAR OLD VEHICLE FIXED. I HAVE OWNED MANY NEW CARS AND HAVE NEVER HAD THIS MUCH OF AN ISSUE AS I HAVE HAD WITH A KIA WITH UNDER 100,000 MILES ON IT. *TR
