NHTSA complaint #11506143

Owner complaint summary

I purchased a pre-owned certified 2019 Hyundai Santa Fe from a Hyundai dealership on 10/13/2020 and the vehicle had 21,770 miles. Then on 10/25/2021 (vehicle mileage was 31,950), I was driving my vehicle on the onramp to i-10 West lanes at Gessner Road. As I was accelerating at 40 mph to enter the freeway, my car engine seized and immediately I lost the ability to accelerate since the engine died. I immediately pulled over and had my car towed to the local Hyundai Dealership, HUB Hyundai Mitsubishi West. The Hyundai Dealership Service Manager, Daniel Castillo (832-739-6353), inspected my vehicle and after an inspection of the engine/underside of the vehicle, Hyundai found no damage or impact on the vehicle or the underside of the vehicle besides a missing drain plug. Their analysis concluded that the full result of the mechanical issue with the engine was a result of the missing drain plug which caused the oil to leak from the engine. Hyundai denied the warranty on the engine citing due to the drain plug issue is a direct result of a third party, Brake Check, that recently changed the oil (See attachment). The Brake Check Store #545 (11564 Westheimer Road, Houston TX 77077) had conducted recent oil changes performed on the vehicle on 12/8/2020 when the vehicle had 24,300 miles and on 5/5/2021 when the vehicle had 27,681 miles. I filed a claim (#3419328-1) with Brake Check for the damages however after 5 months of correspondences I was denied since I could not prove they did anything and the drain plug was missing. I also tried to file a claim with my personal auto insurance carrier, Progressive, however I was denied since the claim did not involve an accident. There was no warning lights that ever appeared on my dash prior to the incident. However, when I did go home that evening, I noticed a fresh large oil stain on my driveway were my car had previously be parked. The oil stain just occurred that day (See attached photo)
