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.

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.

While driving on U.S. 69 highway in Overland Park, Kansas, the engine in my 2018 Kia Forte suddenly failed without warning. I was entering the northbound lanes from the 95th Street on-ramp and was accelerating to merge at about 50 mph. There had been no prior warning lights or messages. Just after getting into the right lane to merge with traffic, the engine lost power and the car began slowing down quickly. I had vehicles behind me that were still moving at highway speed. I had to react immediately, and fortunately the driver behind me was able to brake. I turned on my signal and coasted as best I could to the shoulder of the highway. Only after the failure did the check engine light come on. The engine never restarted and the vehicle had to be towed. This incident created a serious safety risk to me and to other drivers on the highway. A car entering the highway and then immediately losing power is not something other drivers expect, and I could have been hit from behind. There was no prior warning or symptom before the failure. The vehicle has since been diagnosed by a Kia dealer as needing an engine replacement.

the engine was burning oil unknown to me. You had an oil change completed at 101k miles and 106k miles and there was no oil left in the engine per mechanic. This caused the check engine light to turn on. Upon running the engine scans the code for a crankshaft error was discovered. P0017 The mechanic has now stated that a new engine is required due to the damage done to the engine because of the oil loss.
