What owners say
Tl* the contact owns a 2009 hyundai sonata. While driving various speeds, the "ESC off" warning indicator illuminated and the vehicle stalled. The contact stated that the accelerator pedal would not accelerate the vehicle forward when depressed and that the vehicle lost power. Pacifico hyundai in philadelphia, pennsylvania was made aware of the failure. The manufacturer was not made aware of the failure. The vehicle was not diagnosed or repaired. The failure mileage was approximately 130,000.
While driving through a deep puddle (3-4 inches), the battery light comes on as the engine stalls and I lose all power accessories. Once I restart the engine, the battery light goes out after a short time and all is good again. This has happened a few times in the last year I've had the car. I am concerned that if it happens at the wrong time, I may not be able to steer away from trouble.
During the last couple of weeks of rain, we have had multiple occasions where our vehicle has lost power steering and our battery light goes on during low speed operation. . There was no deep puddles, just normal rain on streets. In some cases, total stall and others engine screeches and restarts. Without warning. Filed complaint with hyundai america. Took to dealer. Was advised this was a known problem for 2007-2009 hyundai sonatas. And there was no known fix . Had vehicle checked. Advised all splash guards and shields in place. Could not be duplicated at dealership. One service rep at dealership advised his wife has same problem. All belts and pulleys and tension springs ok. We are very disappointed in the response we have received at hyundai to a "known " safety problem. To be more specific, five(5) occasions have occurred. Told to come back when it rains.
