KIA Complaints

My white paint is bubbling off and peeling down to the metal and it is all over and continues to do so more and more everyday. I am afraid to wash it for fear of having it all come off. It looks terrible and will really look ugly and value comes down quick enough on these cars as it is. It needs to be fixed or something. Can a lemon law be done on the manufacture or something? I still owe on this car and it will be really ugly in a month or so. Something needs to be done about these cars.

While driving 8/24/2026 on interstate engine light started flashing then staues on and car decelerated and knocking noise.Got to closest parking lot. Car would no longer move and turned it off. Contacted a tow. Tow driver verified battery good, oil good and started car, the motor shook uncontrollably then it was turned off and towed to dealership. Full service oil change was done 8/23/2026 at dealership. Dealer stated diagnostics engine failure need replacement. since owning would not support 5000 mile oil change and was reported to dealer due to need service earlier.

I purchased a new 2026 Kia Carnival EX and noticed an unusually intense amount of heat coming from underneath the vehicle on the passenger side, particularly around the rear passenger door/second-row seating area. I first noticed the issue while the vehicle was parked and I was standing outside the open rear passenger door installing car seats and floor mats. The heat radiating from underneath the vehicle was intense enough that my feet and lower legs became extremely hot while standing next to the vehicle I also noticed that the seat/floor rails and other exposed metal components in and around the second-row passenger area became extremely hot to the touch. I could only keep my hand on some of these metal components briefly before the heat became too uncomfortable and I had to remove my hand. I am concerned about the safety of this condition because these hot surfaces are in an area routinely accessed by passengers, including children entering and exiting the second row. I am concerned about the potential for contact burns as well as whether the amount of heat being transferred into the floor, rails, and surrounding components could indicate an exhaust, emissions, heat-shielding, or other mechanical problem. The vehicle is available for inspection upon request. At this time, the exact component or system responsible for the excessive heat has not been identified. The issue has not yet been reproduced or confirmed by a Kia dealer or independent service center. I have contacted Kia service personnel regarding having the vehicle inspected. I was informed that if the vehicle is inspected and the dealership cannot reproduce or identify a problem, I may be responsible for an approximately $210 diagnostic charge. The vehicle has not yet been inspected by the manufacturer, police, insurance representatives, or another independent party regarding this issue. There were no warning lights or dashboard messages indicating a problem before or when I noticed the heat

While braking in a left hand turn lane waiting for the vehicles in front to turn left through an intersection, the vehicle stalled, shut off, and forced a manual restart in the turn lane. This same sequence happened again at another red light when the brake was engaged. The dealership the car was purchased from would not evaluate the car as they stated it is under factory warranty and should be evaluated at the manufacturer. The closest Kia manufacturer has been notified, but they have not inspected it, as they stated they have a lift malfunction and do not have the ability to run diagnostics until at least 10/16/26. No warning lamps or messages appeared prior to the hard stop. After the car stalled, there was a message that appeared stating the car would need to be manually restarted by putting it in park or neutral and engaging the start button. It took 2 tries to restart the car. A police officer did pull up behind me for my safety while the car was stalled, but they let me go when the car restarted. My safety was put at risk as this happened while actively trying pull up to and through a busy intersection in a double left-turn lane. The car stalled right before the intersection while waiting on other cars in front of me to turn left on an unprotected left turn. If I had been braking in the intersection and the car stalled, it could have caused a serious accident with oncoming traffic. I have only owned the car for 45 days. There were two separate occasions in the week prior to this incident where an attempt was made to start the car when parked, and the electrical panel came on, but the engine did not engage. In those instances, turning the car back off then turning it on started the car and no other issues were noted until the issue arose with hard stops when idling at intersections. The car is under 54,000 miles. It is available for inspection upon request.

My 2021 Kia Seltos SX Turbo (1.6L Turbo engine) is experiencing severe, excessive oil consumption, burning (and heavy smoke ) approximately 1 to 2 quarts, (Kia dealer oil change standard amount) of oil every 1,000 miles without any external visual leaks. A formal diagnosis by a certified Kia dealership confirms that heavy carbon buildup has accumulated around the piston rings, causing severe ring distortion. Because the oil rings are stuck and distorted, the engine is bypassing oil directly into the combustion chamber and burning it. This exact physical failure mode—carbon buildup causing piston oil ring failure—is identical to the defect described in NHTSA Recall 25V099 (Kia Campaign SC336) for the 2.0L Seltos models. However, my vehicle is currently excluded from safety remedies due to its 1.6L Turbo engine variant. This vehicle presents a severe safety hazard, including sudden engine knocking, very heavy smoke from the exhaust, power loss, stalling at highway speeds, or potential engine fire due to running dry on oil. Regulators must expand the scope of the piston ring investigation to include the 1.6L Turbo engine footprint. There were no engine lights, oil lights, or any warning codes. I was told by Kia repair service department that although the car was smoking heavy and smelled like it was burning that I should continue to drive it and then I wasn’t in danger. Please help

Acceleration is sluggish and vehicle struggles to maintain freeway speeds. Engine stalls (engine turns off, ACC still on) during normal operation. When reducing speed approaching a stop and for making a right angle turn, only the engine shuts off, all accessories (i.e. lights, climate control, radio and navigation screen) remain on. Tachometer intermittently indicates significant increase in RPM not comparable to vehicle speed. With IGS deactivated and AC off there is no change in engine stall occurrence; gasoline level is sufficient enough to not be a contributing factor and nominal amounts of engine oil is verified, yet an engine ticking is definitely audible. Oil changes (including oil filter replacement) completed every 5,000 miles, along with other milestone services in accordance with Kia preventative maintenance schedule. *there is oil burning somewhere, as the recommended amount only lasts approximately 1,000 miles; however, no noticeable traces of oil are observed in the same spot where vehicle is regularly parked. ***Three occurrences w/similar symptoms, CEL and P001700 via OBDII diagnostic scanner (attached history of dealer service and diagnostics): 1. 2024-10-11 @ 56,990 miles 2. 2025-02-26 @ 61,732 miles 3. 2026-05-01 @ 74,839 miles Each time the following parts were removed and replaced: -24370 2E020 (FP): CVVT ASSY-EXHAUST -24200 2E074 : CAMSHAFT ASSY-EXHAUS -22441 2700 : GASKET-ROCKER COVER -22443 2000 : SEAL-OIL On average, this issue occurs at 14,000 mile intervals (57k, 62k, 75k) which, with diagnostics, parts (12,000 mile part warranty), and labor adds a $2,000 cost to own annually. **Symptoms closely resemble Class Vehicle defects outlined in both: -NHTSA Campaign Number 25V099000 -NHTSA Campaign Number 21V259000 When my VIN is submitted for recall inquiry, neither campaign applies. In the meantime, it's a pain doing so, but I've discovered a delicate temporary workaround: shift to Neutral, press start until engine runs, shift to drive

On or about XXX, my KIA Sorento LX FWD Auto 2.4-liter engine with an approximate mileage of 36,000, began having drivability problems, none of which occurred before that date. On XXX the vehicle was serviced at Ourisman Chantilly Kia (VA051) for a Voluntary Emissions Service Campaign (SC340) THETA II 2.4L GDI ECM S/W Upgrade. Records reflect that it was a Theta II Emissions Logic Improvement 250A21R1 0.3 M/H. This was a voluntary campaign from Kia America, Inc., [XXX]. Failure to have this performed, as cited from the Kia Corporate Headquarters, could nullify warranty/warranties. What ensued was a vehicle that stalled, seized, hesitated, and/or jolted at low speeds that had the potential to cause severe injury or accident. Uncontrolled rough accelerating and seizing is a serious complaint, and the causation can be linked to the dealership performing the voluntary recall where the vehicle was purchased on March 15, 2015, in [XXX]. Further, this vehicle has a full and complete record of all repairs and symptoms, which includes, and is not limited to, maintenance, Service Campaign, Service Action, Recall, and Product Improvement. This vehicle, included in a class of vehicles with a history of potential engine failures, has a Lifetime Engine Warranty extension coverage included in PI1802 Y/Z Engine R&R Warranty Bulletin 2020-26 and PI1802W/X Warranty Bulletin 2018-10. Therefore, when the records were reviewed for the initial Voluntary Emission Service Campaign recall code SC234 completed in 2022, along with my former NHTSA Complaint Number XXX submitted electronically, an apparent history of obfuscation relating to material safety concerns emerges. KIA America, Inc. sold this Kia as a five-star safety rated vehicle. It now makes me feel uneasy with its defective drivability.

Based on reading some service forms, it seems it may be the hydraulic booster, causing the issue. In order for them to take a look at the brakes system. I was charged a upfront diagnostics fee of $316. While driving warning light comes on " Check brake system " then the car slows down to 10mph immediately. While pressing on the brakes they squeaking, very badly. I have to turn the car off and back on until the flashing " Check brake system" turns off. This happens every 5 to 10 minutes while driving multiple times a day, everyday. This could have caused an accident on multiple occasions. When the warning light comes on, the car immediately goes down to 10mph making it impossible to pullover in time. The car is currently at the dealership for inspection, they're the only ones that i had inspect the car. However reading the Kia forms online alot of other customers are having this same issue. This issue started happening about two months ago. And has progressively gotten worse.

The contact's son owns a 2018 Kia Forte. The contact stated that while her son was driving approximately 55 MPH and depressing the accelerator pedal, the vehicle failed to accelerate as intended, with the oil pressure warning light and several other unknown warning lights illuminated. The contact slowed down and pulled over to the side of the road, and the vehicle was turned off. The contact attempted to restart the vehicle, but there was white smoke coming from the engine. The contact raised the hood and inspected the engine, and the smoke had ceased. The vehicle was towed to a dealer, where it was diagnosed and determined that the engine had seized due to a lack of engine oil, even though the engine oil had been changed in June. The contact associated the failure with NHTSA Campaign Number: 21V260000 (Engine and Engine Cooling). The vehicle was not repaired. The manufacturer was notified of the failure, and a complaint was filed. The failure mileage was approximately 100,300.
