NHTSA Complaint #11454194 — 2016 HYUNDAI SONATA

Car began to knock and lacked acceleration. I took it to a dealer and spent $300 on replacement of plugs and it seemed to be working fine. One month later on the highway, the car completely lost power and would no longer accelerate. I found online that the engine had been recalled and the warranty extended to 120K miles. Hyundai paid for a tow to the dealership. The dealership determined that the engine needed to be replaced and thought Hyundai would replace the engine due to the recall, but the replacement was denied by Hyundai. I do not not know at this point on what grounds, but the car has 117,000 miles on it and should be within the extended warranty period because of the recall. The estimate for replacement of the engine is $8000. I've only had the car a few months and expected to get at least a few years out of this vehicle.
