2021 Kia Forte Complaint Log

Driving under normal conditions April 20,2026, on the way to school. Got off the freeway and the vehicle immediately shut-off and the check engine light came on. Vehicle was stuck partially in the roadway and would not move. Vehicle was towed to Kia dealership and they found that there was no oil in the engine and that the oil drain plug was completely missing. This problem caused catastrophic engine failure resulting in the need for a full engine replacement. A routine oil change had been conducted approx. 2,000 miles prior to this on January 12, 2026. The vehicle had been driven daily since that oil change with no noticeable oil leak or problems preceding this event. Had this event occurred at freeway speeds, it could have caused serious injury to the driver and other motorists on the roadway at that time. It appears that the drain plug fell out since there was no other additional or noticeable damage to the oil pan or surrounding the drain plug itself. This information was confirmed by a photograph taken by the dealership conducting the repairs.

The contact owned a 2021 Kia Forte. The contact stated that while driving at 45 MPH, the steering wheel locked independently, causing the vehicle to veer off the road into a construction site. The contact stated that the air bags did deploy. The contact stated that she sustained noise and neck injuries, including placenta rupture, causing early labor. Medical attention was required. The contact stated that a police report was filed. The vehicle was towed to an impound lot. The vehicle was deemed a total loss. The manufacturer was not notified of the failure. The approximate failure mileage was 150,000.

Oil is burning out quickly causing the car to stop abruptly without any warning and caused damages to the engine.

To Whom It May Concern, I am submitting a formal complaint regarding a serious safety issue involving my 2021 Kia Forte. Approximately one year ago, I purchased this vehicle used with approximately 56,000 miles. I have owned the vehicle for nearly a year without prior incident until a recent and significant failure occurred. While driving on a highway after work, the vehicle suddenly lost engine power. The RPMs dropped abruptly, and the vehicle began decelerating rapidly before completely shutting off. This occurred without any prior warning indicators, such as dashboard warning lights or messages. I attempted to restart the engine three times before it successfully turned over. Upon restarting, the engine produced a loud knocking noise that had not been present before. Since this incident, the vehicle has been unable to operate reliably. It will start and run briefly but stalls again after a short distance. The knocking noise persists, suggesting a serious internal engine issue. The vehicle remains in my possession and is available for inspection. Component/System Involved: The failure appears to involve the engine and/or internal engine components. The exact cause has not yet been diagnosed by a professional. Safety Risk: This failure posed a significant safety hazard, as the sudden loss of power occurred while traveling on a highway. This could have resulted in a serious accident, particularly if surrounding traffic had been heavier or less responsive. Inspection and Diagnosis: The issue has not yet been formally diagnosed or confirmed by a dealership or independent repair facility. Additionally, the vehicle has not been inspected by the manufacturer, law enforcement, insurance representatives, or other entities. Warning Indicators: There were no warning lights, messages, or other indicators prior to or during the initial failure. The only symptom Sincerely, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Was currently stuck in slow walking traffic and once traffic began to progress the car overheated engine notice appeared. Pulled into a parking lot as soon as car was parked the vehicle turned off. This happened during the night and was an extremely traumatic experience! Car does have a diagnosis about the engine been blown. Still in the works of being fixed by the dealership. Very long process!

So i took my car to sands kia in surprise az about my seat belts. Both the front driver and passenger belts come unlatched while driving. They said out of warranty so i would have to pay or they will do nothing. This should be a Kia issue. Obviously a defect in the seat belts. I can be driving on freeway and multiple times they will come unlatched while driving. So instead of having both hands on the steering will. I have to fiddle around to get it to latch again. It is a legal requirement to have working seat belts and u feel kia should fix this issue. I told them this and that i didn't feel this was something i should have to pay for and the service writer just asked me if i was leaving then. Hope there is no accident because seat belts won't work and there will be a lawsuit.

I am writing to report a serious safety concern involving my Kia vehicle. Shortly after getting an oil change, my car began making unusual noises and then suddenly stopped working in the middle of a busy intersection. This unexpected stall created a dangerous situation for both myself and other drivers. After having it towed to the dealership, it comes down to an engine malfunction which was not covered by my warranty since it just hit 70,000 miles. I have since learned that other Kia owners have experienced similar issues, and I am concerned this may be related to a larger defect or recall issue. I wanted to report this incident to ensure it is properly documented and investigated.

My 2021 Kia forte GT is currently sitting in my driveway, undriveable. It started about 3months or so ago I had realized I was getting more and more frequent oil changes to the point where the car would be consuming a quart of oil in at least a week or less. Fast forward to this previous week, I now had a hard knock/rattle within my engine. The engine gave way on my way home which is a significant safety issue to myself and those who were driving around me. I have contacted Kia customer as they have had previous complaints as well as a lawsuit on the engine for the excessive engine oil consumption leading to possible engine failure. There’s no reason why an only 4 year old car should have a blown motor. I am thankful that I am personally ok and didn’t hurt anyone else while in the midst of driving my vehicle home.

2021 Kia Forte VIN# [XXX] 107,000 miles While driving my Kia Forte on [XXX] i experienced a sudden noise without warning just 2 months to the exact date after an oil change. The vehicle became unsafe to operate and could not accelerate properly. In some cases it would no have it would feel like it was losing power and creating a scary and dangerous situation. A certified mechanic diagnosed there was no oil in my vehicle which matches the oil consumption defect identified in Kia's Theta II GDI engine recalls and nationwide class action settlement. Kia has acknowledged in public filing that is defect poses a risk of engine seizing and fire. Although my VIN is not currently listed under any active recall, my vehicle exhibits the exact same defect pattern as recalled vehicles, including sudden loss of power at highway speeds which is a significant safety hazard. Manufactures Response: I contacted Kia Corporate to request an engine replacement consistent with the recall and the settlement remedies and they refused to cover the repair solely because my VIN is not included in the recall list despite the defect being identical. Safety Concern: The sudden loss of power creates a risk of rear-end collisions, loss of control and potential fire. This defect can be life threatening and should not be excluded from recall coverage simply due to VIN range. Requested Action: I am requesting that NHTSA investigate why vehicles with identical engine defects, including mine have been excluded from recall coverage and compel Kia to provide a no-cost repair.

The contact owns a 2021 Kia Forte. The contact stated while driving 65 MPH, there was an abnormal rattling sound coming from the engine compartment before the vehicle lost motive power. There was no warning light illuminated. The vehicle was towed to the dealer, where it was diagnosed and determined that the cylinders and pistons had failed, and the engine needed to be repaired or replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The approximate failure mileage was 93,532.

Transmission, yes it’s available. I was driving on the highway and the vehicle began jerking and revving, slowing down and then speeding up. It is at a service center now. Now lamps

On Saturday, March 1, 2025, I took my 2021 Kia Forte LXS for a routine oil change. I had NO PRIOR issues, warning lights or anything with my vehicle. The oil change was performed. I then drove my vehicle less than 20 miles, the vehicle would then not accelerate and started to bog down. I was able to get my vehicle off the major I-4 interstate, however eventually the vehicle then shut down. The vehicle now will still start however is making this terrible clicking noise. I have had video of the engine running looked at by several mechanics who states the engine is blown. I have contacted Kia who clearly has known engine issues on several of their Fortes however Kia continues to state since mine is not currently on recall, they are not taking responsibility. Kia know they have several recalls due to engine issues. I cannot get a mechanic to work on my vehicle due to the recalls as mechanics only want to put in brand new engines due to Kia engine recalls. A new engine will cost upwards of $10,000. Again, Kia knows and had several recalls with engine issues

Component/System Involved: Electric Power Steering (EPS) – specifically, a potential malfunction with the assist motor response timing. Description of Incident: While driving, primarily on the highway, I have experienced a recurring issue with the power steering system. The steering assist appears to delay activation after periods of inactivity—such as when driving straight. When I attempt a small correction (even a movement as small as 1/16 of an inch), there is unusually high resistance, followed by a sudden release. This results in an overcorrection and can create a cycle of steering instability as the same pattern repeats with each correction. Safety Risk: This malfunction poses a safety risk because the delay in steering assist and sudden release can lead to unintended sharp corrections or lane drifting, especially at highway speeds. The issue requires both hands on the wheel to maintain control, and the unpredictable nature of the steering increases the chance of losing control or colliding with another vehicle. Warning Lamps/Symptoms Prior to Failure: There are no warning lights, error messages, or chimes preceding or accompanying the issue. Mileage & Vehicle Info: Several people seem to be having the same issue and it happens at different stages of the vehicles life, but no one seems to have found a solution or source of the problem.

The transmission went out while driving, entering the highway. It was intermittently missing a gear or slipping in about 2nd or 3rd gear. I first noticed it going about 40 mph and trying to accelerate to highway speeds. It was during a winter storm and other vehicles behind me had to brake unexpectedly. I wasn't sure if I felt for sure, so I continued to drive through many inclines and declines. The inclines became more difficult and the inability to maintain consistent speeds. I drove gently to the nearest Kia dealership which was in Salt Lake City about 60 miles away, where they informed me that I needed a new transmission. The car had about 75,000 miles on it and I bought it as a certified Pre-owned Kia with about 4,000 miles on it. The dealership plugged in the diagnostic code reader. But there were no codes detected. The service tech drove the car and felt the issue. A warranty representative inspected it about a week later. There were no warning lamps while I drove (mostly coasting downhill) from Rock Springs, WY. When I arrived to Salt Lake City, the triangle warning light came on. I drove about 10 more miles and the engine light came on. Almost all mileage has been on highways and at highways speeds as I commuted 75 miles each way for work on a turnpike between eastern Oklahoma and Fayetteville, Arkansas. There was little city driving. I lived in a small town. So, I had to travel state highways for most all errands (groceries, medical, etc.). There were no mechanical issues with the car ever until this.

Passenger air bag/seat belt goes off like someone is sitting in passenger seat but no one is. Have to do seat belt for the alert stops

This car was sold to me without disclosing that the manufacture failed to have a engine security system on the car to at least "deter" auto theft.If the key to the car was programmed/chipped like other cars, it would provide at least some level of protection. I've already stopped car thieves from trying to steal it once by pure luck, but I'm like the thousands out there constantly worried that someone's going to try to take it in lieu of the social media challenges.The horrible settlement that out government gave us was to upgrade the software which provides NO help with deterring thieves from breaking in and trying to steal it.The reimbursement provided in the settlement is complete joke, and doesn't offer to properly repair or reimburse for after-market security systems.This is evident from the fact that insurance companies still won't insure this car, even after the software upgrade. The insurance companies are telling me that they still won't insure the car even with upgrade because it doesn't stop thieves from breaking into the car and causing comprehensive damage to the car.I can only find a few insurance companies that will insure the car, and the premium cost is twice as much as I pay to insure a car that's worth twice as much money! If our government or NHTSA was truly concerned, they would have demanded that the manufacture make significant change to the ignition/engine starter, i.e., changing out the ignition switch system with a programmed/chipped key, and/or engine starter kill without said key. If the manufacture and the government made this change a required "recall" to properly fix and advertised it nationwide, THEN thieves would at least be less inclined to cause damage, and insurance companies would feel more comfortable about taking the risk. This ongoing expense/problem for me has me seriously considering if anyone in my family should every purchase another KIA/Hyundai product again. Stand behind your product with some INTEGRITY.

I get regularly scheduled oil changes but the car is making a noise like a rod knock

The rental vehicle, a Kia Forte, was provided by a major rental company without addressing the critical anti-theft system vulnerability identified in manufacturer recall CS2305C. This recall was issued in early 2023, approximately one year before the rental date. The vehicle was stolen on April 11, 2024, using the known vulnerability method affecting the steering column and ignition system. The theft occurred despite normal security measures, demonstrating the effectiveness of the exploit that the recall was designed to prevent. Safety Concerns: Rental company knowingly provided vehicle without performing mandatory safety recall service Anti-theft system vulnerability made vehicle susceptible to theft without traditional forced entry Steering column security system failed to prevent unauthorized vehicle operation No warning indicators were present to alert the renter of this safety deficiency Vehicle Status: Theft reported to police and rental company immediately Vehicle was recovered by law enforcement Insurance company has documented the incident Rental company acknowledged the theft but might be continuing rental operations without addressing recall Severity of Safety Risk: Vehicle could be stolen without specialized tools or expertise Known vulnerability puts both renters and public at risk Lack of proper security systems creates hazard of vehicle theft while occupied Unaddressed recall demonstrates systemic safety oversight failure The rental company's maintenance records would confirm that recall service was never performed despite adequate notice period. This incident represents a broader safety concern about rental fleet compliance with critical safety recalls. Police reports, insurance documentation, and rental company correspondence available for investigation upon request. Rental company's response confirms their awareness of the theft incident and their failure to address the known safety defect. NO PRIOR WARNING INDICATORS

The hood on my car seems to be loose as it rattles when closed and driving. It does appear to be latched, however I'm concerned that the hood will come loose and blow up in front of the windshield while driving causing a life threatening accident. The hood bumpers on the inside of the hood are not adjustable, and/or long enough to cushion the hood to stop the rattling either.

Driving down the highway and sunroof exploded. Sounded like a gun shot

The electric steering column motor has worn parts causing the steering wheel to make a rubbing noise. There is a TSB out for this problem but for cars only manufactured in certain plants. My car was not manufactured in one of the plants that generated the TSB but I have that problem and Kia will not fix it. TSB CHA 084

The issue I’m having was confirmed by the dealership so when I drive on the highway, there’s a specific patch of highway that zigzags the car will follow that zigzag after getting off of the highway onto regular road. The car computer system will start a down shift erratically and feel like the car is pulling backwards. Also there is a lack of acceleration and it feels like the transmission is slipping, but I have confirmed with the dealership that the transmission was not slipping that the computer was shifting erratically. They would reset the computer and the car would would begin driving in a more normal state shifting correctly. I get on the highway again. The car once again will start shifting erratic. When you let go of the gas, the car downshift so many times that the car almost comes to a complete stop without hitting the brakes. The dealership has the car once again trying to figure out what’s going on with the car and why when I go on the highway the computer starts shifting erratically on that specific patch of highway. The car will pull left and right the entire time once you get off the highway the erratic shifting happens the dealership let me borrow a car which is a 2025 Kia Sorrento went on the highway with the car and had the same exact issue. The car they let me borrow is also downshifting erratically and feels like the transmission is slipping. The dealership did confirm that the car was not driving as intended, and they were confused as to why it was happening. They’ve also confirmed that the test that they’ve done on the car itself. had not passed prior to them resetting the computer.

There is loud sound associated with the steering column! It has locked on me before and wouldn’t allow me to turn the vehicle. It has been to the dealership several times only for them to not be able to pinpoint the issue.i have a video but no pictures.

While driving on the interstate, multiple dash lights came on, the engine started knocking and shutting down. The vehicle was towed to the dealership and was found that the oil plug had fallen out, causing the oil to drain out and ruin the motor.

Transmission overheating and dragging… weird smell and noise and scrubbing sound when turning the steering wheel. Only 50k miles on car

Service engine light turns off then comes back on. Get message engine failure. Scanner at dealership scanned 15 codes relating to misfires on all cylinders. Positive battery terminal caked up real bad causing arcing and melting plastic. Last I heard from dealership was possibly a engine replacement.

I am so sadden and broke. My Kia 2021 Forte was stollen.The car has just about 8k miles. The thieves had busted rear passenger side glass, torn down steering column, opened electric wiring Skelton and taken away the car. Police said they found my damaged car. I was also told that my damaged car was towed and was kept at auto body shop. I'm so depressed, upset. Its difficult to express in words how saddened I'm at loss in all aspects - physically, mentally, emotionally, and financially since the vehicle was stolen.

On May 13, 2023, I was involved in a severe frontal collision on the passenger side while driving my 2021 Kia Forte. The impact caused significant damage, and my insurance company declared the vehicle a total loss. Despite the severity of the crash, none of the airbags deployed. I experienced body pain for several days following the accident. Given the nature of the collision and the damage sustained, the airbags should have deployed to protect the occupants. This raises serious concerns about the reliability of the Supplemental Restraint System (SRS).

I was driving down a highway with no other cars near me and heard a loud noise (sounded like a gunshot). I pulled over and my sunroof had exploded. The glass was facing upwards not downwards. It appears it exploded from the inside not by a foreign object.

My Kia forte 21 that I owned for less than 2 years, stalled out while driving on 20 April 23. The engine light came on. I checked the oil and there was none , despite having regular maintenance being performed. No light indicators appeared informing me that my vehicle had no oil left. My vehicle had 21,234 miles when the engine failed. Kia has yet to contact me or assist me with this matter. I could’ve possibly died while driving on the highway and my car randomly stalling out.

Engine is very noisy for quite some time before getting quiet. 40000 miles. Lifters making a lot of noise. Possibly a failing oil pump.

It seems the car may have a defect in the transmission(Dual Clutch). The car makes at times an abrupt stop, for like a second or two, after I press on the gas. When I'm driving, especially at low speeds I can hear the transmission's parts make a grinding sounds, loud clicks. When I'm breaking, it's not smooth at all; I feel the car pulling a bit when switching to lower gears during the breaking process. When I have the car on and not moving (i.e parked), I can hear sounds emanating from the bottom of the car, like parts grinding against other parts. I have not seen any indicator light turn on from the vehicle, to this day. I have taken it to the dealership before, more than once, but they haven't found any issues with it. Still I feel they have not done a full inspection of the car, and I feel something is off with the transmission, like there's something loose somewhere in the car.

1.Vehicle on spots of highway will apply the forward collision warning system and suddenly brake that may cause a collision with vehicle behind it. 2. Theft is sweeping the nation for Kia/Hyundai vehicles and this vehicle is a target. Hyundai/Kia need to install security protocols on their product as this should have been on the product since purchase.

My vehicle was stolen and recovered a couple of days later. The only damage to the vehicle is a broken window and broken ignition dash Currently trending is the Kia challenge where vehicles from 2011-2021 are missing tan anti-theft feature that makes it an easier target to steal. Kia is aware of this and not doing anything about this, not even sending a letter advising their customer of this trend and how we can protect our vehicles. The vehicles need to be recalled because currently millions of customers are driving a vehicle that can be stolen at any time with something as basic as a USB cable. Kia needs to take responsibility and accountability for this major flaw. Now customers have to be left dealing with the insurance and proving to them they are not involved in their own vehicle thefts. I have police report number, still waiting for the actual police report.

The contact owns a 2021 Kia Forte. The contact stated that while his mother was driving at 20 MPH and attempting to complete a left turn. another driver failed to stop at a red light, as a result, the contact's mother was struck by the other vehicle on the passenger's side; however, the air bags did not deploy. In addition, the seat belt failed to retract. No warning lights were illuminated. The vehicle was towed to a repair shop for body repair but was not taken to the dealer or an independent mechanic to determine why the air bags did not deploy. A police report was filed and injuries were reported. The contact's mother did not initially seek medical treatment but was later treated by a chiropractor for back pain resulting from non-descript injuries sustained during the accident. The contact also stated that his mother had later been involved in 2 additional vehicle accidents during which the air bags again failed to deploy; no further police reports or injuries were reported. Following the third and most recent incident, the vehicle again was not taken to a dealer or independent mechanic for diagnosis though the contact's mother was informed by the body repair shop that the collision was insufficient to trigger air bag deployment. The manufacturer was not notified of the failure. The failure mileage was unknown.

My car was stolen. Steering column busted ignition switch taken out. Passenger side window busted.

My main issue is concerning a critical design flaw that has been found due to a social media challenge called the Kia Challenge where people are able to start up and steal a Kia after only using a USB cord adapter (found near the key start on the steering wheel) without needing a key. This has caused a concerning increase in the theft of Kias across the country which has also affected my insurance rates. After repeatedly trying to contact Kia for two days on August 2nd and August 3rd, I was finally able to get in contact with customer service concerning the recent issue with Kias (model years of 2011 to 2021 with manual key start steering wheels) that are being stolen by just using a USB cord to turn on the car without a key. After waiting on hold for an hour, the customer service agent was extremely rude and uncaring about my concerns as my area is also being affected by these recent car thefts. My insurance rates have also gone up due to the overall riskiness of owning these cars and their likelihood of being stolen because it has a key start for the engine. After doing research on the information available to me, I found out that Kia higher-ups approved measures to cut the costs by not including automobile immobilizers that have been the industry standard for a little over 20s years. It makes no sense that my older 2018 model Camry has industry standard parts but my 2021 Kia Forte does not. I am highly aggravated that I am stuck having to pay for a vehicle that has a higher likelihood of being stolen all because the company wanted to save a few dollars and not include immobilizers on their cars until the 2022 models. I am highly upset that Kia, their reps, and dealers have displayed an abhorrent lack of concern in trying to fix this issue as this prevents me from having to go to important job sites for work. This issue needs to be resolved as soon as possible. Link to story https://www.insider.com/tiktok-kia-challenge-using-usb-cables-to-steal-cars-2022-7

My car was stolen from in front of my home, they were able to steal my brand new car because they popped off the bottom steering wheel cover and used an iphone charger to start the ignition and drive away.

While driving down the highway, the entire crank pulley system fell out from under the car and onto the highway.

Ticking sound under hood at 35000 miles

When I abruptly have to step on the brakes to stop the vehicle, the backseat behind the driver and the middle seat fall forward. This has happened multiple times.

The contact owns a 2021 Kia Forte. While driving at various speeds, the check engine warning illuminated. The vehicle would start to vibrate. The vibration was more evident while slowing down or stopping at traffic lights. The vibration and the warning light had become a recurring failure. After turning off and restarting the vehicle, the check engine warning light was cleared. However, lately, turning on and restarting the vehicle failed to clear the warning light. Additionally, the vehicle lost motive power and stalled several times. While the vehicle was stopped and idling, the RPM was fluctuating as if the accelerator pedal was depressed. The vehicle was taken to the same dealer several times; however, the dealer was unable to duplicate the failure. The contact was advised that the vehicle was in good working order. The vehicle was not repaired. The manufacturer was not informed of the failure. The failure mileage was approximately 125,000.

Recall

Vehicle has issues where transmission actuator will stop functioning causing sudden loss of acceleration. Was doing 70 MPH in expressway and vehicle stopped accelerating. Issue has occurred two times, both times being serviced by Dealership, after receiving the vehicle back, issue still persists, vehicle lost acceleration suddenly when turning into a intersection.

A defect in 2021 Kia Forte vehicle engine start and security systems allows for the rear window to be broken without an alarm activation and the car to be started without a key or key-like device. The vehicle can be started with something as simple as a screwdriver. Vehicles of this make and model are being targeted by criminal activity and it is a safety concern for Kia consumers and drivers. Kia is aware of this defect and has issued a statement that all future vehicles will come with improved safety systems and an engine immobilizer, but no recall on vehicles before the 2022 model year have been made for repairs or adjustment to solve the issue. My 2021 Kia Forte was stolen from my house while I was home and which failed to cause a triggered alarm. There were no possessions in the car and the vehicle was locked. The individual who stole the vehicle only had to pull off my steering column cover and the ignition box to steal the vehicle. This is a rising concern throughout the nation, and Milwaukee currently has a class action suit for this safety defect. A new car with no history of problems and very little usage should not have this problem.

The contact owns a 2021 Kia Forte. The contact stated while driving 70 MPH, the vehicle started to decelerate while the RPM increased. The contact pulled over to the side and notice the vehicle smoking but there was no fire. There were no warning lights illuminated. The contact towed the vehicle to a local dealer, where it was diagnosed and determined that the transmission needed to be replaced. The vehicle was repaired however, the failure persisted. The manufacturer was informed of the failure. The failure mileage was 35,642.

Car stalled and shut off while in drive leading it to be towed.

Car completely shut down while in drive on 2 separate occasions leading it to be towed to dealership.

The car is making a noise that we finally found out it was the hood rattling. Took it to the shop and the hood latch looks to be secure, and non=adjustable. Was told that the rubber adjustable hood bumpers are too short, however the dealer said that they are correct, but agreed they can't be adjusted anymore to eliminate the noise. This gives us great safety concern that the hood is not property secured, or has a defective latch, in addition to the constant noise that the dealer said they will only address within the first 12 months or 12K miles.
