Got an oil change in a 2019 Hyundai Kona at a Valvoline quick change shop at 50,000 miles. 5 weeks and 1,800 miles later, the oil light came on. A check showed no oil on the dipstick.
Towed to the dealership and they added oil - it poured out on ground. On the lift, the tech found the oil plug lying in the drain pan and no oil in the car. They said that the oil plug was not properly tightened and had vibrated loose over the time since the change. They refilled and the engine operated. But 2 weeks and 200 miles later the engine started knocking. Towed it in to the dealership.
The engine was still full of oil, but the engine had seized from the damage and would have to be replaced. I had the engine examined for any other damage or recall (such as the fuel pump) and nothing was found. Nothing else can be found wrong with the engine not related to the oil loss.
The original oil change business will not pay. They say that the damage from the loss of oil would have shown up immediately, not 200 miles later. Is this correct? Could it have taken 200 miles of driving to show up?
