| Description of the problem | For the second time in just over 3 months, the hybrid system failed (and displayed hybrid system failure / do not drive vehicle) on the 2013 hyundai sonata hybrid. There was no motoring to the wheels after complete stop. The first occurrence is reported in nhtsa report # 11100475 (may 29, 2018). The second occurrence was on wednesday, september 5, 2018. This occurred while backing up. After towing, the hyundai mechanic could not diagnose the problem, even though he tried to mimic the failure situation. Further, error code was not obtained due to automatic reset when vehicle restarted (poor firmware design?). This problem is intermittent and therefore hard to diagnose, especially without recoverable error codes. When problem occurs the driver must strive to get off the road safely and very promptly, since vehicle motoring is lost. Hyundai consumer affairs office is indifferent to the problem, because the vehicle is now functioning, though not truly repaired (vehicle "fixed" itself on reset). Hyundai consumer affairs has closed the problem report (second time in just over 3 months). This is a potentially dangerous problem, since the driver has to immediately stop the car at a safe spot, even if in high speed traffic. |
