What the reports in each category say, in the owners' own words
Driver assistance
Reports naming forward-collision avoidance, lane keeping, back-over prevention, cruise control and related electronic driver-assistance systems.
From owner reports, verbatim
My father was in a fatal vehicle accident in which the car was going very fast and then he crashed into a building. The car then started on fire. The black box was unable to be recovered to check car function. There were no medical findings
Electrical issues since 44K miles I’m at 50 K miles. I’ve complained multiple times and they kept saying electrician wasn’t available. Then they lie about it being a waitlist for a loaner car. All the lights on the dashboard goes on and all the dealership couldn’t diagnose the problem. The second time the check engine lights went out the back up camera. They said it was the back up camera the backup camera was replaced the backup camera now messes up all the time and does not cut on when backing up randomly cut on when driving Kia issue was flashing lights, but they decided to worry about the check engine light, which was the careless converter, they fixed the careless converter And didn’t fix the flashing lights problem. They tried to say the car electrical reason was physical damage, which was false and now the electrical problems are getting worse the gear shifter license to work on the PRND the right brake light in the front and back goes in and out. I don’t know what the mileage is while driving I got a ticket from the cops because of that, the mileage randomly changes and I never know how much gas is in the car when I put in gas.
Steering
Reports naming the steering system — racks, columns, power-steering assist and steering linkage.
From owner reports, verbatim
I was driving home, on my way while driving I approached a curve on my way around the curve my vehicle continued to accelerate to the right as I was going around the curve. I tried to redirect the vehicle back to the left by trying to turn the steering wheel towards the left but I could not control the direction of the way the vehicle continued on. Still trying to turn the steering wheel back towards the left it kept to the right and ran off the road into a tree. Also once impact occurred i don’t remember if the airbags deployed because my head was laying flat on the steering wheel. Once the emergency services arrived I was accessed and removed from the vehicle and transported to the hospital emergency. There were no warning lights or messages what so ever ahead of the accident. A claim with the insurance was filed and also a complaint with the Kia manufacturer was filed. At this time no one has accessed the damages of the vehicle, State Farm has the vehicle at this time.
Unknown Concerning the front passenger steering component. Carfax showed prior accident with minor damage to the front passenger bumper. I purchased the car not long ago and and was hit in the same exact spot. When I looked up the VIN for more information online I came across the safety issue with some other 2023 forte. I'm concerned that my vehicle could possibly have the same issue though it's not showing up right now under recall.
Electrical
Reports naming the electrical system — wiring, battery, charging, control modules, infotainment and electrical accessories.
From owner reports, verbatim
I am reporting a serious and ongoing safety issue involving my 2023 Kia Forte GT. The vehicle has experienced persistent mechanical problems, including a check engine light and multiple diagnostic trouble codes, including P0420 (catalyst system efficiency below threshold – Bank 1), P0300 (random/multiple cylinder misfire), P0304 (cylinder 4 misfire), and P0301 (cylinder 1 misfire). These codes have appeared as stored, pending, and permanent, indicating ongoing and unresolved engine and emissions system issues. In addition to these mechanical problems, the vehicle is emitting strong and concerning chemical fumes into the cabin during operation. These fumes are noticeable while driving and create a hazardous environment for occupants, raising concerns of toxic exposure and making the vehicle unsafe to operate. The vehicle also exhibits drivability issues, including jerking and performance irregularities when accelerating. Despite multiple attempts to have the vehicle diagnosed and repaired under warranty at authorized Kia dealerships, including All Star Kia East and All Star Kia Seigen Lane, the dealerships have refused to properly diagnose or repair the vehicle. I have been informed that my vehicle or account is “flagged in all systems,” and service has been denied on that basis. The refusal to address an emissions-related defect, combined with active misfires and the presence of chemical fumes entering the cabin, presents a serious safety risk. I am requesting that this issue be investigated as a potential safety defect affecting this vehicle.
My low beam headlights seem to burn out at an unusually high rate. Multiple times per year, and this is much higher than any other vehicle that I've owned. I believe there may be some type of electrical issue.
Engine
Reports naming the engine itself — including stalling, misfires, oil consumption, cooling and internal engine components.
From owner reports, verbatim
The contact owns a 2023 Kia Forte. The contact stated that while driving at an undisclosed speed, the vehicle made abnormal knocking sounds. No warning light was illuminated. The vehicle later lost motive power while driving with the check engine warning light illuminated. The vehicle was towed to the dealer, and it was determined that the engine needed to be replaced; however, the vehicle was not covered under warranty. The vehicle was not repaired. The contact stated that a week prior to the failure, the vehicle was taken to another dealer to determine the trade-in value, and no failures were found at the time. The manufacturer was made aware of the failure. The failure mileage was approximately 49,000.

Suspension
Reports naming suspension components — springs, struts, shocks, control arms and related hardware.
From owner reports, verbatim
The right front lower control arm has completely broken/fractured during operation. Kia has previously issued safety recalls SC283 (NHTSA 23V649) and SC306 (NHTSA 24V244) for this exact vehicle model year due to improperly manufactured right front lower control arms that can crack and fail. My vehicle was manufactured in March 2023 (03/23), which is just prior to the official April 12, 2023 recall window. Because the component suffered the precise, catastrophic structural failure described in the federal recall campaigns, it is clear that defective parts were used in production earlier than Kia's current recall parameters account for. This is a severe safety hazard that causes an immediate loss of steering control and places occupants at extreme risk of a crash. I am requesting that NHTSA investigate this out-of-window component failure and pressure Kia to expand the recall parameters to protect other owners. The vehicle was in a minor pothole incident six months ago but suffered no suspension failure at that time. This is a fresh, catastrophic fracture just discovered on the right front lower control arm. The fracture is clean, unoxidized, and brand new, proving it is a recent spontaneous material failure matching recalls SC283/SC306, not old accident damage.
Passenger front side makes noises like something is clicking. It makes like a rattle noise too

Powertrain (other)
Powertrain reports that are not specifically the engine or transmission — driveshafts, axles, transfer cases and differentials.
From owner reports, verbatim
The contact owns a 2023 Kia Forte. The contact stated that while driving at an undisclosed speed, the vehicle inadvertently lost motive power. The contact was able to pull over to the shoulder of the roadway, where the vehicle was able to be restarted. No warning lights were illuminated. The vehicle was taken to the dealer, who diagnosed a failure with the transmission. The contact was informed that the transmission needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure, and a case was opened. The failure mileage was 25,000.
Catastrophic clutch pressure plate failure - while attempting to shift into gear, teeth on clutch pressure plate sheared horizontally when interacting with input shaft. No indicators appeared when failure originally occurred, only grinding sound when clutch pedal is depressed. Malfunction occurred at a stoplight leading to traffic blockage and no major safety risk. However due to nature of failure if issue occurred at speed there would have been immediate loss of power from engine to drivetrain, causing car to "coast" in effectively neutral until stopped. Vehicle has since been inspected and serviced with appropriate parts replaced by Kia certified technician at a dealer. Failure point was unable to be verified at the time and unknown if able to be replicated.

I was driving in a road, when a female deer appeared out of the trees and bushes from the right shoulder of the road. I tried not to hit it but but the deer got in my way. I hit the deer and quickly moved over to the right shoulder. The whole front right of the vehicle was destroyed and the airbags did not open. Sheriff arrived and saw the vehicle, the vehicles debri and the deer which had to be put down. He asked for the vehicles registration and did a report of the accident. The Sheriff then called a local tow company who arrived in a couple of minutes and towed the vehicle to their garage/shop.

As I was driving at about 20 mph coming to a stop my passenger front door unlatched and caused the door to open and the door sensors to go off. This door was in fact locked and closed. Now I’m very scared to drive my car because if I was going faster the door could swing open and would be very dangerous to and to others.

Visibility
Reports naming windshields, glass, wipers, defrosters and mirrors.
From owner reports, verbatim
The contact owns a 2023 Kia Forte. The contact stated that while driving at an undisclosed speed during a rainstorm, she became aware that the windshield wiper was sticking and failed to adequately clear away water from the windshield, severely reducing visibility. No warning lights were illuminated. The vehicle was taken to the dealer, who was unable to duplicate the failure. The vehicle was not repaired. The manufacturer was notified of the failure but provided no assistance. The VIN was not available. The failure mileage was 10,000.
I’m an owner of a brand new a 2023 Kia for less than one year. While driving home from work which is 8 miles drive on a Friday, while sitting at a red light I heard a crack or pop to see that my windshield had spontaneously cracked on the driver side. When I got home, I measured it to be 8 inches, starting at the frame. It’ll probably need replacing as opposed to repair. It is and always has been garage kept.

Brakes
Reports naming service brakes, the antilock braking system, brake hoses, master cylinders or the parking brake.
From owner reports, verbatim
Summary: Unintended full brake engagement at highway speeds caused by electronic parking brake/Auto Hold button defect. Extreme risk of collision. Details: On [XXX], my wife was driving our 2023 Kia Forte GT Line when the Auto Hold and electronic parking brake system malfunctioned. The system fully engaged the brakes without warning while traveling at highway speed, scraping the brake rotors and creating an immediate risk of being rear-ended. This occurred multiple times. The following day ([XXX], the brake pedal would not depress at all, rendering the vehicle undrivable. The dealership (McFarland Kia, North Hampton, NH) diagnosed “a sticky substance” inside the electronic parking brake button, located next to the cupholder. There have never been any liquid spills in this vehicle. The more likely cause is a combination of factory lubrication and normal dust/debris accumulation over time. If such a small amount of dust or residue can trigger unintended full braking while driving, it is a dangerous design flaw that poses a life-threatening hazard to drivers and passengers. The vehicle was repaired after I paid $284.99 out-of-pocket, but I am pursuing reimbursement through my Zurich Vehicle Service Contract. I have also requested an independent third-party brake and rotor inspection, as this defect may have caused further damage. Why this is a safety issue: Sudden, uncommanded braking at highway speeds can cause high-speed rear-end collisions. The defect can occur without visible warning and without any driver action. The defect can be triggered by minimal non-liquid debris, which is unavoidable over the life of a vehicle. I am requesting NHTSA investigate whether this is an isolated case or part of a larger design defect in the Kia Forte’s electronic parking brake/Auto Hold system. This condition should not be possible in a vehicle that meets federal safety standards. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
My 2023 Kia Forte keeps automatically braking and coming to a complete stop when pulling out of a parking space. It does it in drive and in reverse. On January 4, 2024 I was pulling out of a parking spot on the road and when my front end was completely in the road the car came to a complete stop and I came very close to causing a collision with another vehicle. I’ve had it to the dealership for service 4 times and they duplicated the problem on my first visit and told me they feel my car stopped because it detected a curb and their resolution was to turn off the front end collision assistance safety feature. On the 3rd visit they said my tires did not even roll because I had snow in my wheel wells and that’s why my car stops but my wheels roll I drove my car there. On January 27, 2024 I dropped my car off to another service center who as of today still has my car and they are looking into - car automatically braking/stopping - front end collision assistance failure - blind spot warning lights lighting up and car beeping while on a two lane road - and another attempt to repair back passenger window not rolling down This car is very dangerous for me and my children to ride in and dangerous for other vehicles and passengers as it automatically stops with no warning and no reason . Below I will put the first date it was in for service for these issues as I was unaware I should have wrote down each date this has happened but it has happened many times.

Exterior lighting
Reports naming headlights, tail lights, turn signals and other exterior lighting.

Electrical issues since 44K miles I’m at 50 K miles. I’ve complained multiple times and they kept saying electrician wasn’t available. Then they lie about it being a waitlist for a loaner car. All the lights on the dashboard goes on and all the dealership couldn’t diagnose the problem. The second time the check engine lights went out the back up camera.

I don’t know what the mileage is while driving I got a ticket from the cops because of that, the mileage randomly changes and I never know how much gas is in the car when I put in gas.
The oil in the engine constantly sludges even with regular maintenance with full synthetic oil, I went over a pot hole and two of the rear lights went out and won’t go back on even after replacing bulbs and wiring harness, and the worst of all is the suspension, the lower control arm and the trailing arm both have gone out after only 20k miles of light mostly highway driving, this car offers nothing but problems it’s no surprise that they discontinued the model it’s an absolute nightmare. I bought it brand new and it feels like I’m going to die in it, every speed bump or pot hole I go over feels and sounds like I’m hitting a wall, I’ve replaced the ball joints and am thinking about replacing the control arms because I’m worried they are going to break. I completely understand that living in San Fernando valley there are worse road conditions than usual but I’ve never had a car fall apart like this from driving out here. What’s worse is even after having to have parts replaced with OEM parts IMMEDIATELY the replacement parts are beginning to wear out, I can’t go over speed bumps that are higher than a few inches without scraping the bottom of the car because the car is riding low, I suspect the coils and struts are also already going out also, just the most terribly engineered vehicle, I don’t know if it’s due to something that should be recalled but it absolutely feels like it is to me and I know many other people are suffering through the same issues with their fortes.

I am reporting a serious and ongoing safety issue involving my 2023 Kia Forte GT. The vehicle has experienced persistent mechanical problems, including a check engine light and multiple diagnostic trouble codes, including P0420 (catalyst system efficiency below threshold – Bank 1), P0300 (random/multiple cylinder misfire), P0304 (cylinder 4 misfire), and P0301 (cylinder 1 misfire). These codes have appeared as stored, pending, and permanent, indicating ongoing and unresolved engine and emissions system issues. In addition to these mechanical problems, the vehicle is emitting strong and concerning chemical fumes into the cabin during operation. These fumes are noticeable while driving and create a hazardous environment for occupants, raising concerns of toxic exposure and making the vehicle unsafe to operate.

The check engine light turned on when starting the car. The car was shaking and running rough. The car was towed to the dealership and cylinder misfire was detected. Since the car is less than a year old and around 6000 miles, this needs to be addressed by the company. This accident happening while the car was on the road could have caused serious injuries and concerns.
