| Description of the problem | Coil springs. We live in a cold climate state and our concerned that our coil springs might be defective or corroded like the spring problems in the 2011 sonata models. We own the 2013 se sonata model which one would think has a better suspension than the standard model, apparently that is not the case. After a flat tire on a paved county highway (car in motion at 45mph) on march 6, 2017 we found out that both front springs had to be replaced after normal driving (70k mileage). Dealership told us passenger front spring breaking likely caused our flat tire and once in the shop, they discovered other spring was cracked and needed to be replaced as well. We had not encountered any major road hazards when the flat tire occurred. Car was more noisy after last service at dealership december 27, 2016. Service included oil change, tire rotation and a required under body corrosion treatment. Our ride sounded more noisy like when snow tires are placed on a vehicle, dealership and myself thought it was just from the recent tire rotation, but the noise lasted until the flat tire incident which occurred with a rumble like sound from the tire area and a sudden loss of air noise from the tire area, it sounded like releasing air from an air hose. Dealer rep mentioned he's seen thousands of repairs, but only a few spring problems with sonatas and only 1 other time it involved a sonata with 2 broken coil springs and in that case a driver went over very severe, rough railroad tracks when the springs failed, we never encountered a "bottoming out" nor any hazardous road conditions prior to the springs failing. |
