Mileage when the problem started
Owner reports
Selected complaints filed with NHTSA by 2017 Kia Forte owners, lightly cleaned up (personal details are redacted by NHTSA).
The contact owns a 2017 Kia Forte. The contact stated while making a stop the vehicle stalled. The vehicle was taken to an independent mechanic who replaced the fuel pump, but the failure occurred several times. On a different occasion the vehicle stalled and shut down completely. The vehicle would not start. The vehicle was towed to a repair facility where they replaced the vapor canister purge valve and the canister solenoid, but it did not repair the vehicle. The vehicle then was towed to a Kia dealer where they did a fuel injector service and clear codes and a transmission fluid flush on the vehicle, but the failure reoccurred. The dealer was not able to determine the failure. The manufacturer was not contacted. The failure mileage was 94,777.
At 86575 miles after routine check ups at the dealership and routine maintenance being done regularly my check engine light came on I tried to put gas in my car and it sprayed all over me and the car and the gas tank I can't put gas in my car and the dealership is expecting me to cover this costs and I've seen many other documented incidents with the same complaints
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 as at work and received a message that there was a large oil spot where my car had been parked overnight at home. I checked my oil and it was not low. After work I was on my way to get my oil changed/checked and after 13 miles I heard a light knocking sound. I pulled over and checked my oil. My oil level was still good. I started my car and the noise was gone. I only had a few miles to the oil/lube express. Just as I pulled in the driveway of the business, the noise started again. The problem was the Oil Pressure Sender Unit was bad. The mechanic pushed it back on and I made it home without any noise. I called the dealership and the earliest they could make me an appt was 3 weeks out. No loaner car, my car had just ran out of warranty, and my car did not come up on recall for the list of Engine recalls. I bought the part and a recently retired certified KIA mechanic replaced it. …
I purchased this vehicle second hand at 43k miles. The issue began around 50k miles and would rough idle when coming to a stop and a check engine light appeared. At 55k miles it was taken to a Kia dealership where they were unable to diagnose the issue. They ran a diagnostic and found nothing. Shorty after, the issue persisted. I took it back to the Kia dealership where they were able to run another diagnostic on the check engine light, and they told me it was the spark plugs. I did not believe this as my father has been a technician for over 40 years and said that the issue seems to be an ignition coil issue. I never took the vehicle back to any Kia or IRF since. I've replaced 1 coil and the issue smoothed out. …
Starting around 50k mileage, the engine experienced misfire-like issues: rough idling & transitory reduction of power during acceleration and cruising. This was brought to the dealership multiple times, but the check engine light had never come on, nor were there any error codes saved in the OBD system. After 60k mileage, the check engine light did come on temporarily, but would automatically clear, still without any error codes saved in OBD. Around 65k mileage, the vehicle could not accelerate to highway speeds, so I had it towed to the dealer and refused to take it back until they found the issue. They then observed an error saved in OBD showing a misfire on cylinder 3. Replaced all spark plugs + coil packs, which seems to have corrected the problem. After 70k mileage, I observed that the engine burns oil, about 1 quart per 3k miles. …
I purchased a 2017 Kia Forte from a used car dealer. Two weeks after I picked up the car, the car stalled at intersections. I checked it out at a Midas and they found that oil was not getting to the engine and it needed a new engine. I towed it back to the dealer because it was within the Lemon law, under 75,000 miles. He said he fixed it, and replaced the engine, but after I picked it up, the same thing happened. I towed it back again and printed a list of mechanical things to check that was online. The second time, he said they cleaned the engine. I am concerned that there is a serious problem with the car and it is not safe to drive. I would have to restart the car and it would stall again. I have not picked up the car a third time again.
1. The knock sensor failed. As a consequence the vehicle will not run properly. 2. The vehicle has been at Fred Beans KIA of Langhorne for several weeks. I assume that it is available for inspection. 3. The vehicle will not run properly. It will not accelerate when the gas pedal is pressed and the engine often stops running. Very dangerous on highways and heavily traveled roadways. 4. Yes the problem has been confirmed by Ciocca KIA of Trenton, NJ. Frank's Service Center 645 Knowles Ave., South Hampton, PA 18966 and Fred Beans KIA of Langhorne, PA 19047. 5. Yes. See attached report. 6. Yes there was an engine warning light and a message on the screen.
My car is stalling. Stalled on the highway. Has knocking sound. And if i let up off the gas at all it stalls. Will stall in neutral as well. Was involved in an accident last year and airbags did not deploy even though they should have. My car started stalling at 86,000 miles with regular oil changes. I've only had the vehicle about a year and a half. My lights also are shorted out due to the trunk not closing all the way and rain water getting in. I'm still making payments. I do not know what to do. I'm a sole caregiver to my terminally Ill mother. I need this car. I do not make very much money.
