KIA Complaints

2016 Kia Sorento 2.4 mileage 75,500 (just out of warranty as of Jan 2026), vehicle is having transmission issue, hard shifting/jerking from1st gear to 2nd gear on first cold start-up of the day. No warning lamps on. Took into Kia to have the transmission serviced, cost $462, did not solve the issues. Kia paperwork upon completion of service paperwork stated "No further action required, Transmission operates to manufacturer's specifications". Safety issue: vehicle may stall during operation.

The contact owns a 2014 Kia Sorento. The contact stated that while driving at various speeds and steering left or right, the steering wheel would seize. The contact would have to maneuver the steering wheel back and forth for it to unlock and continue driving. There were no warning lights illuminated. The vehicle was taken to a certified mechanic, who diagnosed a notch in the lower steering shaft as the cause of the steering failure. The steering joint assembly was replaced. The manufacturer was not made aware of the failure. The failure mileage was 132,538.

The vehicle began showing serious safety related symptoms before the engine failed. These included engine knocking, repeated sensor failures, the speedometer and odometer blacking out while driving, the navigation screen going dark, and the entire instrument cluster malfunctioning. These issues caused loss of speed information, loss of vehicle status, and loss of navigation visibility, creating unsafe driving conditions. Despite these warning signs, the engine later failed suddenly at around 71,399 miles with no warning lights, no oil pressure alerts, and no overheating indicators. The sudden loss of power created a highway safety hazard due to loss of propulsion and reduced steering and braking assist. The manufacturer and dealership also provided conflicting and misleading information about warranty coverage, including a claim of “no warranty on engine,” which contradicts the official warranty coverage documents. This has delayed proper repair of a safety related defect.

The contact owns a 2021 Kia Seltos. The contact stated while driving at an undisclosed speed, the contact noticed an unusual knocking sound and the engine seized. In addition, several warning lights were illuminated. The contact stated that while attempting to start the vehicle, the vehicle started.

The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The contact referenced an unknown recall; however, the VIN was not associated with a recall related to the failure. The manufacturer was not made aware of the failure. The failure mileage was approximately 60,000.

The seat was able to move forward with the seat adjustment buttons. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the issue. The approximate failure mileage 20,000.

The contact owns a 2016 Kia Soul. The contact stated that while driving at various speeds the vehicle suddenly stalled. During the failure the odor of fuel was present. The failure had occurred on several occasions. The vehicle was towed to an independent mechanic who diagnosed that catalytic converter and damaged exhaust muffler. The vehicle was not repaired.

The ABS/traction warning lights came on. On April 29,2026, I took it to Beck and Masten Group 1 Kia inTomball, Texas and they diagnosed as HECU failure. The repair cost $2377.16. KIA corporate denied reimbursement. Lights were resolved after HECU replacement. There was no accident/injury/fire. mileage was 60400. I wanted to note and document as a potential safety trend.

While driving on an open highway, my panoramic sunroof spontaneously exploded on [XXX] coming back from Prescott with me behind the wheel, my husband as a passenger, and my dog in the backseat. There was nobody driving in front, near, or behind me. I was not driving near an overpass. The incident sounded like an explosion or gunshot. My husband began to open the sunroof visor to investigate, and glass began dropping into the car. Once we could pull over safely, there was a large hole on my panoramic sunroof. My husband, dog, and I had tiny pieces of glass on us. I took my car to Kia, and they refused to acknowledge that anything, but a rock caused the problem. There are numerous news stories about this being a problem and also recalls for panoramic sunroofs from other dealers like Hyundai, who are made by the same manufacturer as Kia.

Windshield chipped and cracked. Causes a safety issue due to temperamental glass and vision impairment. McKenneys garage has viewed the damage and confirms the damage. No. No.

My 2019 Kia Sorento equipped with a Theta II engine entered limp mode and displayed a flashing check engine light along with an active P1326 diagnostic trouble code. The P1326 code is a proprietary Kia/Hyundai specific code that can only be generated when the Knock Sensor Detection System (KSDS) software update is present on the vehicle. This software was developed and distributed by Kia specifically to detect Theta II engine bearing failure and rod bearing wear before catastrophic engine damage occurs. The presence of the P1326 code is confirmation by Kia's own proprietary detection system that this engine is experiencing the exact failure pattern associated with the Theta II engine defect. The vehicle was towed to an authorized Kia dealership. The dealership refused to perform a BTC test or enter the vehicle into Techline, citing that the VIN does not appear in the Theta II settlement database. Kia America customer care has also denied coverage. The vehicle remains inoperable. Safety risk is significant. The Theta II engine defect has been directly linked to engine fires in Kia and Hyundai vehicles. Limp mode and sudden loss of power while driving creates serious risk of accidents, injury, or death to the driver and other motorists. The 2012-2019 Kia Sorento is a model year range specifically identified in Theta II multidistrict litigation. Kia's own KSDS software flagging a P1326 code on this vehicle while Kia simultaneously denies any defect-related coverage is contradictory and raises serious safety concerns for owners whose VINs were excluded from settlement but whose vehicles are exhibiting identical failure symptoms.
