Engine Noise problems of the 2015 Kia Motor Forte

Just financed from a dealer on 4/12, had major oil leak, had to return to dealership. Supposed to have been fixed, but currently still have a bad oil leak. Still waiting for a week for an appointment to take it back to the dealer to have it checked out. Engine makes a noise when idling, almost like a "miss".

While driving in city or highway, you hear engine noise, see illumination of the check engine warning light, illumination of the low oil warning light. Then vehicle propulsion stops suddenly, continues to coast but pressing on the accelerator has no effect, the engine doesn't rev. Stopping, turning off engine for 30 or more minutes may allow vehicle to start and move again. Also fuel smell.

I had suddenly engine made sound shutter , I almost got hit by 18 wheel truck, I manager to pull finelly and avoid accident and manage to pull right, firar it was close to side rails . The car had sp much engine noise , and it cuts of. 1. 8 engine was wonderfull . I wanna this engine to repkaced by dealer has only 78 thousands miles.

When the car accelerates from a stop, there is severe valve pinging sound. Kia motors America is aware of the issue, but are not taking any steps to address the issue "as it does not do anything to the car". The noise is very severe on the 2015 Forte and it is a defect in the design of the car. The wind noise and the valve ping make the car very loud. The dealer says that since Kia Motors America is not addressing the issue, nothing can be done. Kia motors America has been aware of this issue for years but have failed to do anything about as they are do not care about their customers. Recommendations include upgrading to better gas, but the noise still persists. Kia recommends and advertises regular unleaded for the Forte, but a more expensive plus or premium grade is needed to decrease the sound of the ping. There is an additional added expense to the car that kia fails to address.
