2019 Hyundai Accent

my vehicle had a fuel injector lock open flooding the car until it damaged the O2 sensor and also contaminating the engine oil. the car went through about two and a half gallons of gas in 3 minutes. during the repair process I mentioned to the dealership that the engine oil smells like gas and was a quart and a half higher than what it was after the last oil change 5 days prior. I'm believing the Quart and a half was most certainly all gas. the dealership informed me they could not repair the oil as it was not covered under warranty. if I wanted to dispute the warranty I had to contact Hyundai customer service. That was April 25th 2023 and as of May 23rd 2023 despite repeated phone calls Hyundai customer service they have never called me back. there are 2 safety issues in regards to this 1. when the fuel injector locked open dumping two and a half gallons of gas vapor in 3 minutes could easily have led to a fire or worse. 2. refusing to replace the contaminated engine oil is a safety issue because gas in the oil will cause the engine to fail. if this happens on the interstate which I drive all the time it could lead to a catastrophic accident involving me and other cars. eventually because I didn't have the money the dealership comped the oil change (I do not have the money for the change because had I changed the oil 5 days prior to the breakdown). the dealership recognized the safety hazard from contaminate engine oil but Hyundai motor company of America refuses to even call me back and if they had it their way would I would have just had me drive in a vehicle that represented a danger. the repair invoice has the oil change listed as warranty but it was not likely to be covered by warranty as the service customer service manager informed me they're going to have to fight with Hyundai and will probably end up competent in the long run. this was after 2 weeks of fighting with Hyundai to get them to pay for it and still they have never called me back.
