| Description of the problem | This is a 2009 hyunda sonata, bought new in 2009. Under 20,000 miles, when the car speed is slowing down, the engines started to give a sudden jerk at around 21 miles. You can feel a sudden impact and it is more noticeable during winter. Many trips to the dealership went to no where as the dealer simply ignored the problem and mentioned that they did not notice any issue. After many trips to the dealership at around 45,000 miles in 2014, the dealer finally agreed that it was a problem. Updated to a new software based on bulletin from hyundai, mentioned that it would go away. Now under less than an year, i started to notice this problem again. |
