KIA Complaints

Vehicle: 2022 Kia Forte LXS I am filing this complaint regarding a complete air conditioning system failure on my 2022 Kia Forte LXS, which is fully covered under Kia's 5-year/60,000-mile bumper-to-bumper warranty. The vehicle has been driven under 60,000 miles and has no accident history. The AC system failed completely. I brought the vehicle to an authorized Kia dealership for diagnosis and repair. The dealer recharged the refrigerant system, however the vehicle is still not cooling properly. The dealer has been unable to provide a confirmed diagnosis after multiple days, citing either the compressor or heating core as potential causes, but has not committed to a repair timeline or parts order. Of additional concern, the dealer has suggested 'outside influence' then said on the 4th say it maybe mechanical failure, but we have to check more of the compressor and heating coil as a possible cause despite my vehicle having no accident history, no modifications, and being only 4 years old. This appears to be an attempt to deny a valid warranty claim without evidence. I have an open case with Kia Consumer Affairs, however corporate has deferred entirely back to the dealer with no resolution or timeline. I am currently incurring out-of-pocket rental car expenses due to the dealer's backlog of loaner vehicles. I am requesting that the NHTSA investigate this matter. A complete AC system failure on a nearly new vehicle with no external cause raises serious concerns about manufacturing defects in the 2022 Kia Forte AC system. Desired Resolution: Full warranty repair of the AC system at no cost to me, and reimbursement of rental car expenses incurred during the repair period.

While driving southbound on Route 93 on 6/11/2026 during the morning commute, my 2021 Kia Sportage suddenly sputtered and lost the ability to accelerate. I was traveling about 65 mph in heavy traffic when the vehicle abruptly lost power without any warning lights or prior symptoms. As my speed dropped, I had to cross multiple lanes to reach the breakdown lane, creating a dangerous situation for me and surrounding drivers. The vehicle had to be towed to a repair shop, where I was informed that the high-pressure fuel pump had failed and needed to be replaced. The car has only 22,000 miles on it and is just one month out of warranty. This sudden loss of drive power at highway speed poses a significant safety risk.

The contact owns a 2017 Kia Soul. The contact stated that while driving approximately 65 MPH, a loud knocking sound was heard, and the vehicle's speed decreased to approximately 25 MPH. The contact was able to safely pull over into a parking lot. The vehicle was towed to the contact's residence. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure. The approximate failure mileage was 197,000

When attempting to disengage the cruise control, I must apply sufficient force as to actually apply the brakes. My expectation is that a simple tap on the brake pedal would release the cruise control and begin a coasting mode. This is not the case; the SUV continues at the same forward speed until I press the brake pedal the second time a little harder.

The contact owns a 2025 Kia K4. The contact stated that while driving at 75 MPH, the vehicle downshifted upon depression of the accelerator pedal, with heavy white smoke coming out of the exhaust pipe. The contact stated that the low oil pressure warning light was illuminated prior to the failure. The contact pulled off the highway and drove into a store parking lot as the engine made an abnormal knocking sound. The contact requested assistance from a bystander, who advised the contact that the head gasket appeared to have blown. The contact checked and noticed that the coolant and oil levels were low. The contact added both oil and water to the vehicle and drove to the residence. The contact made a diagnosis appointment with a local dealer. Upon starting the vehicle, the check engine warning light illuminated, and the contact decided to tow the vehicle to the dealer. The dealer determined that the engine needed to be replaced due to sludge. Additionally, the contact stated that the vehicle had experienced various electrical failures, as the trunk, power door, and power windows buttons were inoperable. The contact also stated that the rearview camera image remained displayed while in drive(D) for an extended period. The contact was provided an estimate for the repair, and the vehicle remained in the dealer's possession. The manufacturer was notified of the failure and provided a case number. The vehicle was not repaired. The failure mileage was approximately 58,000.

The contact owns a 2022 Kia K5. The contact stated that while driving approximately 45-50 MPH, the automatic front collision avoidance system abruptly engaged while there was a vehicle was parked on the passenger-side of the roadway. The contact stated the parked vehicle did not present a safety hazard to the vehicle. The dealer was notified of the failure; however, the vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 9,000.

I am writing to formally complain about the delay in repairing my vehicle under an active recall involving the fuel system/crossover fuel pump. I have been informed that the required part is on backorder and that the repair may not be available until the end of July. My concern is that I am experiencing strong fuel fumes in and around the vehicle. The odor is severe enough that it is causing headaches, and I do not feel it is safe for me or my children to ride in the vehicle. Given that this recall involves a fuel-related component, I am extremely concerned about both the health effects of continued exposure to the fumes and the potential risk of fire. At this time, I do not believe the vehicle is safe to operate. I am requesting that Kia provide an immediate solution, including one or more of the following: A loaner vehicle until the recall repair can be completed; Rental vehicle reimbursement; Expedited repair assistance; or Any other reasonable accommodation that ensures my family's safety.

My vehicle experienced a dangerous incident involving smoke entering the passenger cabin followed by complete engine seizure. Prior to this failure, the vehicle had already undergone recall-related repairs through an authorized Kia dealership for known engine and fire-related safety concerns. The recall was marked as completed by the dealership. However, after the repair, the vehicle continued experiencing problems significant enough to require multiple return visits to the dealership. Despite the recall work being completed, the vehicle ultimately suffered the same type of dangerous condition the recall was intended to prevent. Smoke entering the cabin created a serious safety hazard for myself and anyone inside the vehicle. This was not a routine mechanical issue or ordinary wear and tear. This involved conditions directly connected to known Kia engine defect investigations involving engine failure and fire risks.

The Hydraulic Clutch Actuator has caused functional driving issues and caused my vehicle to go into limp mode. I was never informed of the recall issue prior to purchase, and the recall was marked as complete, when it was not. The fix for KIA NIRO Recall SC276 was incomplete in January 2024, and I purchased my vehicle in April 2024. My issues started in November 2025, and the incomplete recall issue has been ongoing. KIA offers only a 1/2-way fix, and this is simply not acceptable.

While driving on the highway on Mother’s Day weekend with my wife and daughter, the vehicle suddenly lost acceleration and engine power while traveling on a 5-lane beltway. The vehicle would not accelerate and I was unable to maintain normal highway speed. I had to coast to the side of the road with the hazard lights activated because of the safety risk. The vehicle was eventually restarted after being towed to a dealership, but it continued to have severe loss of power and could not safely travel above approximately 45 mph. The suspected failure involves the engine and emissions system. The vehicle has a history of engine-related issues and previously received engine-related repairs. The current engine has developed excessive oil consumption. This condition has resulted in fouled spark plugs and a catalytic converter becoming severely restricted/clogged from oil contamination, causing significant loss of engine performance. A dealership inspected the vehicle and documented the oil-burning complaint and catalytic converter-related fault. The dealership performed diagnostic work, including spark plug replacement, but the problem continued. An independent repair facility also inspected the vehicle and confirmed excessive oil consumption and catalytic converter restriction. The vehicle remains available for inspection. This condition presents a safety concern because the vehicle experienced a sudden loss of power while traveling at highway speeds and was unable to maintain normal traffic speed.
