Hyundai Scammed me to Recoup Costs for their Engine Recall

I am the owner of a 2014 Hyundai Sonata that I have had for about 6 years and that has 80,000 miles. On 10/3 we had a flashing engine light issue. A local autobody recognized it as a known engine recall issue at Hyundai and that we should bring it to the dealership. We were unable to get an appointment with our local dealer until 11/3. They took the car and we informed them of our suspicions of the engine recall issue. Our case manager reported they couldn’t make assumptions and needed to do a series of checks. On 11/6 he called to report the engine light was a software issue fixed under warranty. However an oil lamp issue(known) and coolant leak issue(unknown) would cost $700. The car was picked up on 11/7. Round trip we live 80 minutes from the dealer. About 15 minutes from home the oil lamp turned back on and the car began overheating. 2 miles from home it broke down in the middle of the road. We were stranded and needed to get our own tow home. Getting a hold of our case manager the following day was extremely difficult and it felt like he was screening our calls and only picked up when we called from unknown numbers. Getting him to assume responsibility of the breakdown and agreeing to pay for a tow back to the dealership was like pulling teeth. The car finally went back and on 11/23 they reported it was an oil pump issue which they replaced for $2000. We picked up the car and 20 minutes away the engine light began flashing again. We immediately turned around. Upon arrival our case manager was not in a rush to see why we returned. Finally, we explained the issue and that we felt all of these ‘fixes’ we’ve paid for were Hyundai’s way of recouping lost costs from having to replace engines and that they knew it was the engine issue all along. They still wouldn’t admit it was the engine, showed no remorse for our predicament and provided little solution besides leaving the car again. As a last resort the mechanic volunteered to replace the knock sensor(under warranty) as that may be the last known issue. We waited 2 hours and surprise, it wasn’t the issue and they finally admitted the engine would need to be replaced under warranty. No timeline could be given and they had no rental cars available, also with no timeline when one would be provided. Almost 2 weeks later we’ve had no communication from the dealer with no idea when the car will be tepaired or when we will get a rental. I’ve been without a car for 2 months and out $2800 with no idea if Hyundai will rectify this issue or when they will fix my car. I would never buy another Hyundai and I do not recommend anyone else does either.
