Loud Engine Noise problems of the 2017 Hyundai Santa Fe

Vehicle has 57,000 miles, I was driving down the highway and the engine lost power and would not accelerate over 40. I stopped at gas station and filled up. When I started the car again it seemed ok, got back on the expressway and heard a loud noise and engine stopped. Had vehicle towed to dealership and they said the engine is blown and it needs a new engine. Only has 57,000 miles so should be under warranty. Dealer gave me a loaner and I drove home. . Car died in michigan, they towed the car to greenbay wisconsin to the nearest dealer, and I live in chicago. The dealer called a few days later and asked for all oil change documentation. . Most of it was in glove box which they found, had oil changed at Hyundai dealer in illinois in March of 2020 right as pandemic started , car had 45,383 miles at that time. Dealer did not use synthetic oil according to receipt which is strange because manufacturer requires synthetic. Could not a more recent receipt but did have oil change one more time about 6 months later, again during pandemic. Dealer said that oil looked sludgey and they denied the warranty claim for the car. They billed Hyundai 18,000 to put a new engine in my vehicle and Hyundai denied the claim. Dealer said he would put a used engine in the vehicle for $7,920. 00 with a 1 yr warranty. We declined and the dealership said they would now charge us for the tow and 30. 00 a day for use of the loaner. We live 200 miles from the dealership. They asked us to return the vehicle or they could come pick it up, the car is close to the mileage that they cannot sell it as a new car and want to keep mileage down. They told us on Feb 5 that the could not come and get it until Feb 10 and that they would bill us 150. 00 for 5 days it would take them to pick up the car. We see that there have been many engine recalls on Hyundai and we think ours probably have same issues.

Ok from the start first let me state ive never had any problems what so ever with my 2017 Hyundai Santa Fe limited ultimate 3. 3l awd none nothing so this was very strange because ive always maintained the vehicle oil changes every 3000 miles everything. So here we go one afternoon about a month ago I just happened to start my Hyundai with the door open and when I started it I heard a sound for like 2 seconds. The sound of an engine that was low of oil that tap tap tap I really could not believe that I just heard that I mean really could not believe it, it doesn't leak anything its never did that before. When I get the oil changed they don't say it was low on oil so I'm very dumbfounded at this point theirs no oil on the ground were it gets parked so I don't know why it did that. So I check the oil and sure enough it's low so I find out what kind of oil it takes and put 1 and then 2 and finally 3 kinda woundering and kinda in shock so to speak. Well the next day I checked the oil and it was still were itvshould be and had to drive to san diego from long beach were I live and it's not the first time I've made this drive mind you. So im off no lights on dash no smells no noises o smoke thinking cool so after passing throu oceanside I thought I'd get something to eat so I decided to take the first exit after oceanside camp pendleton so I get off and before I stop for the light the vehicle stalls what the this has never happened before not thinking anything bad because again no lights on dash no noses no smells no smoke no nothing. So I tried to start it and nothing try again and nothing lights on but does not want turn over. I have no idea what's going on because no lights on the dash came on theirs no smoke no loud noises or anything before it stalls just nice and quiet no smells nothing just the car getting real quiet. Well I tried a couple more times best regards eric.

There's always a 2-3 seconds hesitation in situations where acceleration is necessary. After 2-3 seconds of hesitation after stepping on the pedal for acceleration, the car revs and produces high pitched and loud sound with no acceleration or accelerates abruptly. Quickly merging into highway, making turns, changing lanes from a full stop and slow movement feel like playing russian roulette. Hyundai service center always claims they cannot replicate my complaint and my concern is ignored.
