2024 Hyundai Elantra Engine Problems

My oil plug fell out causing engine damage. They are saying it is fault of wal mart who did last oil change but 2 months and 12,000 miles have passed since oil change and they will not cover under warranty

I had my oil changed in September at McGovern Hyundai in Leominster, MA. I have the invoice on file and my app that I have with them. I went out of town on [XXX]. At approximately [XXX], I heard a loud pop, saw smoke and immediately pulled over, a large amount of oil came out of the bottom of my car. The car was undrivable and I had to have it towed to the closest Hyundai dealership in North Plainfield, NJ. They provided me with a write up that stated I need a new engine due to the damage. We called McGovern and they are claiming that is isn't their issue and to contact my insurance company or cooperate. The cost right now is over $11,000, $300 for a tow, $200 for an uber driver to my destination where I was going, $223.86 for a diagnostic test, $350 car rental for my parents to come and get me, approximately $100 in gas fees to get me and my dad lost a day of pay. This all happened just a little over 1,000 miles and there is only 14,421 miles on the car. The dealership I bought it from isn't taking responsibility for it and Hyundai has yet to. This happened on a major highway on NJ and I was left on the side of the highway alone for over 2 hours waiting for a tow. This was such a scary and dangerous position to be in. This seems to be an issue with Hyundai cars and they aren't helping. I am now without a car and no one seems to care.

I was driving around 34 miles per hour in traffic and my speedometer turned red indicating a problem. I attempted to accelerate in traffic and it made a funny noise and would not speed up. I was able to drive home which was about a mile away. Once I got home I turned the vehicle off and back on and the speedometer was blue again. I took it to the dealer and they advise they could not locate the problem , They put it on a level 3 scope and drove it a lot. Since then it happened as I left home and I stopped the vehicle and started it again which solved the problem. The car has around 3100 miles.I was not at risk because I was in slow traffic and could run about 30 mph during the first event.

New vehicle was recently purchased at Hyundai dealership odometer reading 8 miles only. Four days later while driving the engine turns off and all dashboard lights start flashing vehicle stops completely in the middle of the road I immediately turned-on emergency lights to make the cars behind me aware. Looking on my rear mirror I notice a vehicle wasn't stopping and I was about to get rear ended so I suddenly wave my hand out, thankfully he passed right by me, and all traffic slowly comes to a complete stop. There was no warning lamps, messages or problem prior failure. I took the vehicle back to dealership for service maintenance I was informed no problem was found and it was a onetime thing they guaranteed me it wouldn't happened again and unfortunately it did.
