NHTSA Complaint #11468901 — 2017 KIA FORTE

Engine can stall at lower speeds (10-30 mph) after being on the highway for an extended amount of time. Can also happen after being on the highway, parking and waiting for some time (30 min), and start driving again at lower speeds. Issue becomes more prominent when going uphill slowly (little to no pressure on gas pedal). A rumble can sometimes be felt through the gas pedal too, but not always. Usually the engine starts making some noise ('gurgling') to indicate that the engine is in this state and it usually stall after coasting for some time or pressing very little on the gas (noise may become louder when doing this). I've seen the engine stall around 1000 rpm when doing this. Sometimes the oil light will also start appearing and it seems that the engine is not being responsive when pressing on the gas pedal. Car can stall in these cases or may recover and eventually stall. I've had this issue since the beginning of the year, but an engine check light has not come on for it since then (other than one for a spark plug and coil, but this was addressed in February 2022). Safety concern is mostly when driving in cities or at lower speeds and making unprotected left/right turns where the car may possible stall. Mechanic was able to reproduce this in February but suggested that I take the car to the dealer after difficulty finding the cause . Dealer was unable to solve it in April and suggested waiting for a check engine light.
