Started with 'check engine' light. Dealer telling us there are no issues driving this car because there are no current resolution for this 'engine light'. Then 'check charging system' light with the car shutting down at the middle of the road. Had to get it tolled to local dealership.
Our 2011 Hyundai Sonata purchased 30 April 2010 could not be started on 4 occasions since date of purchase (keyless, pushbutton). Fortunately, the events occurred either in the garage or on a parking lot. After "muscling" the steering column left-right and/or playing with the shift lever, the car started after some time. The brake pedal was hard in all cases.
