2016 Kia Forte: sudden loss of power

Filed Jan 10, 2026 · Acceleration, Airbags · OH

I am filing a formal complaint regarding serious safety and mechanical problems with my vehicle. The brakes do not function properly and I have to add brake fluid every few days, which indicates a possible leak or brake system failure. This creates an extremely dangerous driving condition. The vehicle also has electrical problems, including malfunctioning lights. The engine has lost power, making it unsafe to drive, especially in traffic or on highways. In addition, the airbag warning light is on, which means the airbag system may not deploy in a crash, putting me at risk of serious injury or death. These problems have made the vehicle unreliable and unsafe to operate. I am requesting that these issues be inspected and repaired immediately at no cost to me, or that the vehicle be replaced or refunded under warranty or consumer protection laws. I am concerned for my safety and the safety of others, and I expect this matter to be handled urgently.

While driving my 2016 Kia Forte with my [XXX] daughter in the car, the engine began making loud knocking noises and quickly deteriorated until it became unsafe and undriveable. This failure occurred without warning lights, oil pressure issues, or prior symptoms. We were nearly stranded in an unsafe location and had to immediately pull over and arrange alternate transportation. I later learned this issue aligns with a known defect in Kia’s Theta II engines, which have been recalled or covered under extended warranty in many cases. However, Kia has denied any support, stating my vehicle is “outside the factory warranty” and disqualified due to not completing a knock sensor software update I was never notified about. How Safety Was Put at Risk: My daughter was in the vehicle at the time, and we were placed in a vulnerable position with a failing engine, unable to safely continue driving. A sudden loss of power could have resulted in an accident if we had been in traffic or on the highway. This defect is a serious safety hazard, especially for families with young children. The vehicle has not been inspected by Kia directly since they declined to assist once they determined the factory warranty had expired. I am happy to make the vehicle available for inspection upon request. Warning Lamps or Messages: There were no warning lights or indicators prior to the onset of the knocking and failure. The symptoms began suddenly and escalated rapidly. My Request: I am requesting an investigation into Kia’s handling of these failures, particularly in cases where families were not properly notified about knock detection software updates and are now being denied support for what is clearly a known and widespread engine defect.

While driving our 2016 Kia forte 5 the engine completely failed and lost all power while on a busy highway. The engine in this vehicle was not part of the original 2016 Forte Recalls for the same issue and is not part of any current recalls for the same issue. It could have led to very severe injuries or even death due to the failure and complete loss of engine power only. Battery power remained on the car.

We have a 2016 Kia Forte 5 that did not meet the criteria when the other 2016 Kia Forte's were recalled due to engine failure as it has a 2.0L engine. On or about [XXX], while driving this vehicle, the car lost all power and came to a stop on a busy highway. It still had electrical power, but failed to accelerate and we lost the ability to steer or control the car. We were able to get it off the road and called for a tow. The car was towed to a repair shop and we were informed that the engine failed, and needed to be replaced. This is the same situation that is occurring with the current Kia engine recalls. The garage attempted to contact Kia and we were told that due to the car not selling well in the US, it was considered a niche vehicle, and therefore no recalls were made. The car was in perfect running order with no signs of failure, no lights on the dashboard to warn of a malfunctioning component, and no audible sounds of a failing engine. Our safety, as well as others, was put at risk due to the car losing all power on a 55mph road that is heavily travelled and could cause an accident. The engine was inspected by a certified mechanic and all they can determine is that the engine failed and it needs to be replaced. This placed my wife in a dangerous situation that could have ended badly. To date, the car has been towed back to our home and sits in our driveway as there is no current fix to it, but the reason for the original recall on the 1.6L engines, and the current recall on Kia engines, is the same that occurred with this vehicle.

Was fixing to head and get my oil changed even though i still had about 570 miles left before i absolutely had to change the oil, my 2016 kia forte LX with the 1.8l engine with 79996 as of currently; lost power at around 15mph and started lugging after leaving my neighborhood gas station, luckily i was about 1/8 mile away from a kia service center so i drove it to the service dealer so i could hear, "We only have lube technicians because all the maintenance technicians quit so we cant check your vehicle for mechanical failure, and we are booked until march 2024." So i parked my car and called kia customer service where they told me that the recall is only applicable to the 1.6l and the 2.0l engine, the 1.8l is only warrantable to 60k miles being i am the second owner and the car is passed the 60k mile marker I was told "we would be happy to take a look at it but it will be an out of pocket expense being insurance doesnt cover an engine. This is the second time this year this specific incident has happened to me and i will not be buying another kia or hyundai vehicle ever again. Let this be known to all kia buyers these are cheap cars you get what you pay for.

Was driving and car lost power and shut off while in traffic car would not restart

On May 25th 2023 I was driving on the highway when I experienced extreme loss of power and the infotainment screen displayed "possible engine condition". Considering I was driving 70 mph on the highway it was super dangerous because there were several 18 wheelers driving on the highway alongside me it could have been deadly for many of us. Thankfully I was able to get to the shoulder to assess the situation. I have been unable to get my vehicle to a dealership since I was traveling and had to leave my vehicle 150 mi from where I live. If Kia knew there was some sort of issue with engine failure and extreme loss of power they should have issued notification before other than have people possibly die on the highway from engine failure.

Pulling out into traffic, without warning my car lost power and shut down! The car had to be towed to the dealership who advised that the engine had a catastrophic failure and needed to be replaced. I was told by the dealership that KIA would not cover the repair for two reasons: 1) I was beyond the warranty period (the car has 60,264 miles on it and apparently as the second owner I am only covered up to 60,000 miles not the 100,000 that comes with the car), and 2) despite acknowledging that they engine had a defect, KIA did not issue a recall to fix the problem. Instead, they issued a performance improvement notice. KIA also acknowledged via a phone call on 3/10/23 that they have mailed these notifications to the previous owner rather than to me. I have on a number of occasions conducted recall searches on which does not list the known engine defect! It seems underhanded for KIA to recognize a defect and instead of reporting it as such and issuing a recall, they hid the problem behind a deceptive "performance improvement" label. It's not a performance improvement!! It's a known defect that if not fixed, it will result in a blown engine and COSTLY bill for the owner!!! the federal safety agency SHOULD IMMEDIATELY ISSUE A RECALL AND REQUIRE KIA TO REPAIR OR REPLACE THE ENGINES IN THESE CARS. THEY SHOULD ALSO REQUIRE KIA TO REIMBURSE OWNERS WHO HAVE HAD TO REPLACE ENGINES NOT COVERED BY THE WARRANTY!

When driving on a divided four lane highway, after about one hour and at about 60 mph, vehicle would not accepperate to pass. Loss of power in traffic. Felt like transmission slipping, but the check engine light came on. P0240 code. It got progressively worse. An experienced mechanic diagnosed it as the engine, and was not sure I could drive to dealership. I had it towed. The warranty (10 year, 100,000 mile), covers engine, as agreed by delar. First, the dealer said it was catalytic converter $2200. When questioned, price was "corrected" to $1,200. Most for part and less than one hour labor. On a differen phone call, repair cost increased to $3300, saying the tech mistakenly thought it was the cat near muffler, but its the cat near engine, and comes as one pice with exhaust manifold. I am waiting on written estimate that I requested, and the dealer assurance there are no other problems with the car. I suggested they drive the car, and see that the problems are the same ones they used to have to video tape and send to Kia to get repairs approved on other engines. Still waiting on the written estimate and the assurance from dealer there is no safety risk in me driving it home. I can buy the Kia part they say it needs for about $500.

While I was driving I lost power and the car would hardly move. I had to get it towed to the kia dealer. The tow truck driver informed me that his broy=ther had the same car and this happened to him also. He than told me there was a defect in the engine and since it is still under warranty the engine is cover. He also stated that after the 5 year warranty there will be a recall. This put me at some ease but I knew it was only here say. The dealer said it was my fault since I did not properly maintain it. I always get my oil changed and if I don't show proof it is not covered. I do not have all my receipt, the garages close to my house just put them on paper receipts with know computer record. The dealer is 10 miles further away than my local garage. I gave the keys to the kia dealer and told them to keep it. If its 's under warranty with about 44,000 miles why isn't it covered.

While driving my vehicle loses power while going above 65 MPH and shutters when losing power. It also burns 1/2 quart of oil per week while driving or in use. Also when refilling oil there is a white substance on the dipstick when checking the oil levels. When it loses power while in motion the electronics dim or flicker. This have been on going for about 3 weeks now. This is an apparent engine failure like other forte's.

Car cuts off while driving all warning lights will cut on the car slows down then comes to a stop. There is no warning when car is about to shut off. Does not lose power but wont let me accelerate. This happens while driving on main roads and streets, freeway. The vehicle starts back up immediately. According to kia dealerships there is nothing registering that is wrong with the vehicle when placed on there diagnostic machine.
