Incident

The contact owns a 2018 Kia Forte. The contact stated while driving at an undisclosed speed, the vehicle failed to accelerate as needed. There was no warning light illuminated. The vehicle was taken to the dealer, and it was discovered that the engine oil level was extremely low. The dealer kept the vehicle for nine months and performed an oil change. The failure persisted. The vehicle was taken back to the dealer, who replaced the oil gasket cover, but the failure recurred with the engine making knocking sounds. The vehicle was taken back to the dealer and determined that the engine had failed and needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure, and a case was filed. The failure mileage was approximately 104,000.

Recently, while my boyfriend was driving my vehicle, the engine suddenly lost power without warning. He had the accelerator pedal fully depressed, yet the vehicle would barely move. He was fortunate to safely maneuver the vehicle off the road. Upon inspection, he discovered there was no oil present in the engine. Critically, neither the low oil warning light nor the check engine light had illuminated prior to this failure, providing absolutely no warning of a severe mechanical problem. After adding oil and performing a proper oil change, the engine began violently shuddering and shaking upon startup, and only then did the check engine light illuminate. The vehicle was immediately towed to an authorized Kia dealership, where I was informed that the timing chain had failed.

While driving the car with the flow of busy traffic, the engine failed and the car stopped. It eventually turn back on (side of the road) but now drives with hesitation, a strange noise, and with the engine light on. This cycle continued until we arrived at the repair shop. And after much research, it seems that this experience is common for other Kia engines. Why was mine not included? Someone could have been badly injured!

Engine would run fast and then sound like was going to stop and then it would start shaking and rumbling while driving on highway and in town. Car would stall while at a stop. Gas smells inside the car. Did not feel safe driving. Had the car towed to an independent garage on February 7th and They did an oil change, change 2 Sensors, changed all the spark plugs and changed all 4 Cylinders and on the way home from Starks garage the car was doing the same as before going to the garage with gas smells inside the car, shaking, rumbling and stalling of the engine. And the car wanting to stall while on the highway speed limit of going 60 mph. the next morning My mom and stepdad had the car towed again to another mechanic close to them at Hudson Import Automotive -Napa Auto Care and they emailed a list of problems after inspecting the car. Attaching the list of codes from a diagnostic test from Auto Zone Store # 00791 , and the Estimate for Service from Hudson Import Automotive - Napa Auto Care. Have no paperwork from Starks mechanic shop.

I went to Kia dealership in Groton CT 06340 for an oil change. They also fixed a recent recall, and after I picked up my car, both of my key fobs weren’t working. I can’t open my car. I can’t lock my car and they are refusing to fix it. I contacted kia corporate. they were not helpful. What can I do here to have this situation resolved? I’m worried that the anti theft system doesn’t work now on my car because my key fobs don’t work at all.

No warning lights/ indicators at all. Well taken care of vehicle 84,400 miles on the vehicle second owner. Had an oil change and my husband noticed bad blow by, had it diagnosed by a mechanic. They said we need a whole new engine. Dont understand how this would happen unless some manufacturer defect. No recalls apparently for this vehicle. Seems to be a common issue. Really sucks that I dont even have 100000 miles and need a new engine. We got screwed over as first time buyers with a huge loan ended up paying nearly 30000 dollars for this vehicle and the engine is already no good. I hope something comes of this because people are tired of getting screwed around by major corporations. Theres no reason why my engine should be no good with only 84400 miles and well maintained. Luckily my husband noticed when he did because who knows what would have happened if it had gone out while driving with no indicators that anything is wrong whatsoever. Could have been a bad crash for all I know.

The car turn off while driving it. This creates a serious safety concern. We took the car to a mechanic and he was not able to identify the problem, he suggested we take it to the dealership. We then took it to the kia dealer ( Covina) and they have had it for months and yet are not able to fix it. Yesterday we received a call telling us, the engine failure is related to the oil pressure and it would need a new engine. This is no longer covered under warranty. This same car has already had the engine replaced once before. When we bought the Kia in 2018 (new) just weeks after we took it home, it required a new engine, which Kia replaced. The current issue appears to be related to oil pressure and is consistent with engine concerns reported on this model year.

PITSTOP: TECHNICAL OPERATIONS: EXTERNAL DAMAGE TO ULTRASONIC SENSOR: This Pitstop provides information related to Parking Distance Warning (PDW) alerts and repairs involving ultrasonic sensors. The PDW system alerts the driver while parking, by calculating distance based on the difference in signal transmission and reception times between the vehicle (ultrasonic sensor) and an object. The membrane film of the ultrasonic sensor is used for object detention and can be damaged by stone chips or foreign substances while driving. Damage to the cover of the ultrasonic sensor can also lead to damage to the internal circuit. As a result of this external damage, the PDW system may not receive the proper signal from the ultrasonic sensor. In some cases, the system may cause a false alarm, no alert, or phantom warnings by a “Warning Lamp’ to be displayed on the cluster. The ultrasonic sensor membrane film should be always inspected for external damage and if any part replacement should be treated as a general repair, not as a warranty claim repair for this concern. (Please note that this Pitstop only applies to models/trims that are equipped with the ultrasonic sensors.)
