"I brought my 2016 kia sorento in the dealer for check engine light (code p0172). after the evaluated it, they said the fuel pump and fuel lines need to be replaced because it's leaking fuel into the engine and the engine needs an oil change because the oil is diluted with fuel."
"Check engine light came on. 65,000 miles with documented regular maintenance. Took to dealership where i purchased the vehicle new. Engine code (P0172). Was told gas was getting into the oil and i would need a new high pressure fuel pump. This is a common issue and should be repaired free of cost."
