1. NHTSA Safety Complaint Draft Vehicle Info: Make: Kia Model: Forte5 SX Year: 2016 VIN: [XXX] Engine: 1.6L GDI (G4FJ Nu engine) Issue: This vehicle uses the 1.6L GDI Nu engine (engine code G4FJ), which is the same engine involved in Kia’s engine defect recalls and class action settlements related to connecting rod bearing failure and engine seizure risks. However, Kia is refusing to provide the Knock Sensor Detection System (KSDS) update, and no internal campaigns or recalls are listed for my VIN despite the identical mechanical risk. I purchased the vehicle in 2017 and was unaware of the extended warranty and safety campaigns until now. I am experiencing symptoms of rough idle and pre-knock concerns, and yet Kia and my local dealership are unwilling to escalate my case or even verify warranty eligibility. This defect poses a risk of sudden engine failure and should be addressed under expanded recall coverage. I am requesting NHTSA investigate inclusion of later-production 2016 vehicles like mine, which clearly share the same defective power train.

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.

I had diagnostic ran because of a knocking sound and stalling and the oil pressure warning light. I was informed by the technician that the oil pressure was extremely low. Upon further inspection they found metal shards in the oil filter blocking oil flow. They told me this is a known defect and that Kia should be responsible. Contacted Kia and they said it’s not covered. It has 98,289 miles

When driving slow speeds such as driving through a parking lot my car stalls the radio plays without interruption and would not know it stalls except for the oil pan light and unable to accelerate because the car stalled all the leads me to believe the engine is at fault. When stalled at that point I pull over turn the key off then on starting the car back up (immediately starts without issue). I have searched for error codes and it is like the car doesn't know there is a problem. Below is one of the many forums complaining about the same issue.

SERVICE BRAKES, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
In December 2023 the dashboard ABS, ESC and Brake Dashboard warning lights came on the car while driving. I checked for any ABS codes and noted a C2374 code. The car did not show any handling issues and I attributed it to a anomaly. However over 2024 the lights have come back on but they disapear when the car is turned off and then restarted. As this is happening frequently during the past 3 months I took it to two KIA dealers to have it reviewed. Both dealers say the HECU ( Hydraulic Electronic Control Unit) is failing. As the car now has 110,000 miles on it I was told by KIA that this is passed the warranty and not covered. I am surprised that a safety device is not covered and as this device requires no maintenance by the customer I attribute this to a premature part failure. I note there has been a related safety Recall Report 23E-073 issued for this part. I included the dealers diagnostic reports. If this vehicle is unsafe to drive then I need to be aware of that and KIA should investigate for similar occurrences.

I was two states away at conference for my side job. My car turned off without warning. No lights no nothing. I couldn't use my hazards or anything. It was dark outside already. I called AAA and the person with me called 911. Someone stopped and jumped me off. We got back to the hotel. The next day another consultants husband looked at my car and we discovered there was no oil in the engine. I had driven more than 450 miles to get to conference the day before by myself. The oil light had never came on during my trip. It only came on when my entire instrument panel lit up when the car cutoff. I am a female and was traveling by myself and put over 1100 miles on my car that trip. If it had turned off at any point on my trip before I had gotten to my destination I would have been alone and not known what to do. If I had not had AAA I would have possible had to pay a tow truck that night. I am disappointed that the light didn't give me a warning something was wrong or going wrong. Luckily, I didn't blow my engine

Vehicle is having same symptoms as recalled Kia’s with Nu engine. My engine is consuming oil. I brought it to Kia dealership to have it diagnost and piston rings are not working as they should. This will lead to engine failure. This problem is what is occurring on the recalled Kia’s. I have not had the vehicle for long & am very disappointed in what is going on. I want something done & to have this reported for the other Kia’s who are experiencing the symptoms that don’t have their VIN called. I had my vehicle looked at Cartown Kia in Florence, SC. My tech was Robert & service rep was Kelcey.

SERVICE BRAKES, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, UNKNOWN OR OTHER
I have been on the freeway multiple times and tried to brake and I feel a fluttering from the brake pedal. The car won't brake, it feels like I'm sliding. I have to press the brake a few more times for it to actually brake. I had my brakes replaced and that didn't work. I took it to the Kia dealer and they said the problem was that I had after market brakes. I had them change them out and that wouldn't work either. They say nothing is wrong with my caliper.

SERVICE BRAKES
My car was recalled and I took it in to KIA in June 2023 for brake line treatment to prevent deterioration/corrosion, May 2024 my brake lines now leak and car is not safe to drive. This preventative maintenance did not work for my vehicle and had it towed back to the KIA that handled the original recall 'remedy'.

SERVICE BRAKES, ENGINE
I was attempting to park in a parking spot that I use regularly at Dollar General. As it was coming to a stop, the brakes failed. I was pushing the brake pedal down. The car started to rev up and speed forward on it's own. It lunged forward jumping the curb and into the pillar. It wouldn't stop going forward. So I had to put it in reverse. As I did that, I put the brakes on as well as the ebrake. It was wanting to speed in reverse for a second. So I threw it into park and turned it off. My family and I went into the store to let the car settle down. Then we was able to drive it home and park it. So it's currently sittling in our driveway here at home.

VEHICLE SPEED CONTROL
I was slowly pulling into a parking spot with my foot on the brake and the vehicle suddenly accelerated. I hit the brake hard and the car eventually stopped but it did go onto the sidewalk before stopping. In the past, when I started the car, the engine would sometimes rev too much and I had to step on the gas while in park to get it to stop, but this is the first time it suddenly accelerated while driving. I am contacting the dealer about the problem tomorrow so it has not been inspected yet. I read online that other Kia models have this problem and that a recall is being considered.There were no warning lamps before the problem occurred. My car is available for inspection.

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.

The contact owns a 2016 Kia Forte. The contact stated while driving 40 MPH and depressing the accelerator pedal, the accelerator pedal made an abnormal grinding sound, and the vehicle failed to respond. Additionally, there was an abnormal knocking sound coming from the engine. The contact also stated that the steering wheel became difficult to turn. There was no warning light illuminated. The contact was able to drive to the residence. The vehicle was taken to an independent mechanic, where it was diagnosed that the engine rod was knocking, and the engine needed to be replaced. The dealer was notified of the failure. The vehicle was not repaired. The manufacturer was notified of the failure, but no assistance was provided. The failure mileage was approximately 115,000.

I am writing to express serious concerns about the safety and performance of my Kia vehicle. Over the past few months, my car has been exhibiting abnormal behavior, jeopardizing the safety of myself and other road users. One of the most alarming issues is the unpredictable acceleration and deceleration of my vehicle, especially on the highway. There have been numerous instances where it failed to respond to acceleration while changing lanes, putting me in stressful situations where I feared a potential collision. Even more troubling, my car has shut off unexpectedly multiple times during both city driving and while navigating driveways and hills. This sudden engine shutdown has exposed me to hazardous situations and increased the risk of accidents. There is also a loud knocking sound coming from the car, accompanied by sluggish driving. To my dismay, the vehicle now starts and immediately cuts off, forcing me to wait for a period of time and multiple attempts to restart the engine before it finally starts. Seeking a resolution, I took my vehicle to the Kia Service center, where they advised me that I needed a new engine, attributing the problem to sludge build-up. However, I maintain a diligent oil change schedule every three months and can provide evidence of this fact. Despite filing a claim with Kia of America, they regrettably denied my request for assistance in obtaining a new engine, placing the financial burden solely on my shoulders. This not only presents a financial hardship for me but also underscores a broader issue with Kia vehicles' quality and reliability. I am deeply concerned about the safety of Kia vehicles, and I believe that they should be subject to a thorough investigation and, if necessary, a recall. I understand that KIA has experienced problems with design of this or similar engines, causing recalls of those products, and I request NHTSA to investigate these concerns regarding the 2016 KIA Forte. My Car is available to inspect once more
