Emission Control Problems of Hyundai Santa Fe

The contact owns a 2014 Hyundai Santa Fe. While driving approximately 40 mph, the emission control system warning indicator illuminated and the vehicle lost acceleration. A considerable amount of smoke started emerging from the exhaust pipe. The contact continued driving to an independent mechanic who determined that the vehicle presented a timing default failure and it was using four cylinders instead of six. The contact also stated that the same failure occurred in March of 2017. The vehicle was towed to the dealer where it was diagnosed that the gasket was faulty on top of the engine, causing the loss of engine oil and acceleration. The vehicle was repaired by replacing the gasket and changing the oil filter; however, the failure still occurred. The manufacturer was notified of the failure. The approximate failure mileage was 19,000.

Took my car to a two mechanics who both said there is a gas leak in the evaporator of the emission control system. I read online that this issue is common with Santa Fes and I believe the company should issue a recall and get this dangerous issue fixed.

At approximatlely 50-60 mph the car has a engine miss. Car loses power that can last for a second or more. Problem is a intermittent one. I have had it to the dealer at least 5 times. They have replaced the computer and the mass air sensor but the problem still happens. It seems to happen more when the truck is under load going up a hill, passing.
