NHTSA Complaint #11588083 — 2013 HYUNDAI GENESIS COUPE

Was driving home from work, turned at intersection and car just died while in motion/traffic. No check engine line, no low oil indicator, no overheat, no warning whatsoever. Was able to coast to adjacent intersection and police officer helped push off to side. Tried to restart but engine just wouldn’t turn over. Electrical fine, dashboard lit up. Towed it to my mechanic and he suspected either alternator or intercooler hose failure. But when he checked it out, nothing, inexplicably could not get engine to crank. I’ve religiously babied this car with AMS Oil Full Synthetic - Signature Series SAE 5W-30 every 7.5k-8k miles, premium gas, regularly maintained. Though I am at high mileage (121,873 mi), I honestly expected longer life for the engine. I just got no warning whatsoever. The contact stated the vehicle has exceeded 100k mi warranty by 20k, and wondering what further actions can be taken to get Hyundai to investigate a possible warranty or even partially warranty for repairs.
