NHTSA Complaint #11533917 — 2017 HYUNDAI SANTA FE

While driving on freeway there was a clicking sound coming from the engine area but no other strange sounds or sensations, no warning lights or changes in the dash gauges. Finished 30 mile trip back home. Next morning when starting the car the same noise was happening so we checked oil. Oil reservoir was empty so added 4 quarts and let it sit for awhile then idle before leaving. The clicking noise seemed be random, sometimes louder and faster and sometimes not clicking at all. Approximately 15-20 miles down the freeway (about 60 mph) the RPMs spiked so I moved to slow lane and braked. At this time a large commotion from the engine that shook the car with large amount of smoke coming from behind the car and an oil trail. Car was towed to mechanic where engine failure/hole in engine was diagnosed. Waiting for appointment now at dealership. Fortunately never lost control of the vehicle.
