Vehicle Overheat problems of the 2011 Hyundai Sonata

While driving on the grand central parkway going 50 mph the car suddenly lost all power and stalled. The engine had seized due to loss of oil. There had been no oil warning light. Car had been serviced regularly since purchase. Car was towed to dealer. Dealer informed us that short block needed to be replaced & work was done. We have tried to find an oil warning light on the a instrument cluster and have had no luck so we are not confident this won't happen again, creating another unsafe situation the car did not feel right while we drove it. At one point, about a month or so later, it stalled out. We called Hyundai for a tow but the car eventually started. A week later the car overheated and we brought it to a service station & checked the coolant. It was low & so we added coolant. We also checked the oil & found it down by one quart. (this was about 2 thousand miles after the short block was replaced). Car continued to overheat in traffic. We took the car to Hyundai for service where they discovered that the fan was not working. We asked if it was normal for the car to stall while on the road if it overheats, & we're told yes it was normal. We consider this to be a serious issue with this car. We have filed a complaint and received an incident number but have not received any response from corporate. We do not feel safe in this car or transporting our grandchildren or anyone else. Please contact us a. S. A. P. Thank you for your quick reply to our concerns.
