I purchased this care new, and the manufacture did not disclose that the vehicle was NOT made with an engine immobilizer, or any theft prevention outside a basic door lock. (Kia Hyundai Vehicle Theft Marketing, Sales Practices, and Products Liability Litigation, No. 8:22-ML-3052 JVS(KESx) (C.D. Cal.). I've already stopped the theft once and scared away the thief's, but now I can't find insurance companies to insure the vehicle. The 2 companies that I did find for insurance, charge 15% of the value of the vehicle for comprehensive and collision coverage. Even with the useless class action lawsuit settlement to upgrade the software, this is NOT stopping the thieves from breaking into the cars, and NOT impressing the insurance companies either as they won't insure this expensive asset. I've never seen so much deception in the automotive industry. The government should mandate a recall to install a KIA or aftermarket security system in this car with a starter kill & visual blinking lights to stop the theft. They should also be required to make national awareness messages to communicate that all affected vehicles will have security systems installed and theft will no longer be possible. This would STOP the problems and continuing extreme costs to the customers.

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.

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

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.

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.

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 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.

Oct 24, 2022Transmission & drivetrain

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 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

Apr 11, 2022Electrical systemCrash

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.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2021 Kia Forte Koup verdict →
