KIA Complaints

While driving under normal conditions and normal operation, the engine lost power, began using excessive fuel, the inside of the vehicle smelled like fuel and white smoke began pouring out of the exhaust.

When driving between 20-40 mph and hitting a rough patch of road, pothole, expansion joint, or uneven pavement, the vehicle sometimes heavily sways left to right. It takes one to two seconds to stabilize after the swaying. My wife and I both experience it at different times - we say it "feels like a wheel is falling off" because it's so disorienting and concerning. It often happens unexpectedly with road surface that doesn't actually appear to be all that bad. The rear end feels particularly unstable, like the suspension can't control the vehicle's weight when it's swaying. It's not a small vibration - it's a pronounced side-to-side oscillation. Sometimes I need to make steering corrections just to keep the vehicle centered in the lane. This unpredictable swaying makes us nervous about driving in adverse weather conditions. We can't trust how the vehicle will react when hitting unavoidable bumps and road imperfections. We have noticed it over 50mph at times but it is much more rare at this speed -- though when it happens at this speed it is obviously much more concerning. At higher speeds the swaying does not seem as pronounced / dangerous as at lower speeds, thankfully. After researching online, I discovered many other EV9 owners reporting identical suspension problems. Multiple complaints describe the same lateral swaying, porpoising, and bump-steer behavior that we are experiencing. This appears to be particularly common among GT-Line models. The consistency of these reports suggests this is a systemic defect affecting multiple vehicles, not an isolated incident with our particular vehicle. We have 11k miles on the vehicle now and this has been consistently happening since 200-300 miles brand new. We've mentioned to a dealer but it is very difficult to reproduce as it seems to happen randomly, even over the same stretch of rough road.

The contact owns a 2014 Kia Cadenza. The contact stated that while driving through a car wash, there was water entering the vehicle through the front windshield. The vehicle was taken to the dealer, who diagnosed a failure with the windshield bonding agent. The vehicle was not repaired. After investigating the failure, the contact related the failure to NHTSA Campaign Number: 22V158000 (Visibility); the VIN was included, but the vehicle was previously repaired in 2022. The manufacturer was notified of the failure, a case was opened, and the contact was referred to the NHTSA Hotline for assistance. The failure mileage was 129,000.

While operating the vehicle and utilizing the cruise control, the Electronic Stability Control (ESC) and the Antilock Braking System (ABS) warning lights turn on. These lights will remain on until the vehicle is turned off and a new drive begins. They only activate during the use of cruise control and at times it has caused the brake pedal to become extremely tough to press. This is a concern if maintaining cruise control and an emergency braking situation arises, the brake may not engage it is designed to do and cause a vehicle accident.

Van completely locked up on me. Oil dipstick no oil, seems this is an issue and a Kia problem. Seems I need a new engine. Regular oil changes with no issues prior to this happening to me.

In June 2024, my 2014 Kia Soul (VIN: [XXX] ) experienced a sudden engine failure without warning. I was driving on a busy road when the engine began sputtering and quickly stalled. The vehicle became inoperable and had to be towed. I had it inspected at a Kia dealership, who diagnosed the issue as complete engine failure but have not provided me with a full diagnostic report despite multiple requests. This type of failure is consistent with the known defects in the Theta II engine that have triggered recalls and extended warranties in similar Kia models. Although Kia has denied coverage for my vehicle, I believe this is a related safety issue. The vehicle stalled unexpectedly, creating a hazardous condition on the road. I was traveling with my toddler in the back seat and felt our safety was at risk. I am submitting this complaint because I believe this failure is not an isolated incident and should be investigated. Kia has refused to acknowledge a defect, but the symptoms match those in previous recalls for other Soul and Forte models with similar engines. I have also attached documentation showing service history and repair costs, and I am happy to make the vehicle available for inspection.

The contact owns a 2014 Kia Soul. The contact, who was an independent dealer, purchased the vehicle for resale.

The vehicle was taken to the dealer; however, the dealer declined to repair the vehicle. The contact was informed that, because of missing or incorrect VIN information, the repair was declined. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The manufacturer was made aware of the failure. The contact had not experienced a failure.

The contact owns a 2024 Kia Telluride. The contact received notification of NHTSA Campaign Number: 25V494000 (STRUCTURE); however, the part to do the recall repair was unavailable. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue. The contact had not experienced a failure.

My 2016 Kia Sorento SX AWD shows a noticeable delay in the powertrain when shifting from Park into first gear. The car hesitates before moving, which affects drivability and feels like a transmission lag. I consider this a safety issue because the delay could cause the car to stall unexpectedly. I’m especially worried about driving with my children or merging onto highways, where a stall or hesitation could lead to loss of control and increase the risk of an accident.
