| 2010 hyundai sonata. 9 months old, has been in the service center 5 different times. 2 times for sensor replacement. the last 3 times, driving at a normal accelerate pace. check engine light comes on, esc light comes on and vehicle loses power. on one of those occasions, vehicle lost power while going through intersection, and almost was rear ended. service department has replaced many parts from throttle position assembly to thermostat to electrical wiring harness. in my opinion, vehicle is a lemon. | |||
