2021 Kia Sportage Problems

The hose connected on the antifreeze leak into the engine compartment

On June 14, 2026, the driver experienced sudden rough engine running followed immediately by a flashing check engine light. The vehicle was towed to the selling dealer, which has performed all prior maintenance. The vehicle is currently at the dealership and available for inspection. Technician notes show DTC P1326 was stored — the Knock Sensor Detection System code associated with connecting rod bearing wear on Kia's Theta II engine family. The technician performed an audible knock check only (none heard) and cleared the code. The vehicle was found approximately 2.5 quarts low on oil due to an internal turbo oil leak. The dealer's notes state the code "may be related" to low oil — hedged language, not confirmed causation. The dealer confirmed the turbo failure but has not performed a bearing clearance test to confirm or rule out bearing damage from the low oil condition. The dealer performed a turbocharger replacement. Despite a verbal commitment from the service manager that a bearing clearance test would follow, no such test was performed 40 days later. When the vehicle was declared ready, the service manager did not recall the commitment and suggested driving 40-50 miles as an alternative. Kia America opened a formal case last month and authorized a partial goodwill adjustment but no one has addressed the safety concern of the unperformed engine test indicated by the thrown code. Driving a vehicle with potential connecting rod bearing wear risks catastrophic engine failure, creating a serious safety hazard. This vehicle has a documented history of oil consumption prior to this incident. The engine has not been cleared for bearing damage following a significant low oil event and a stored P1326 code.

The panoramic sunroof spontaneously exploded on the highway. There were no other vehicles nearby that could have thrown any debris at my vehicle. The edges of the glass are pushed out as if the force came from inside the vehicle.

I drove down the road and noticed that the car seemed to be noisy and there was a rattling sound within the headliner. I stopped to investigate and realized that the sunroof had exploded outward.

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's wife owns a 2021 Kia Sportage.

The contact attempted to notify the manufacturer of the issue but could not connect with a live representative. The contact had not experienced a failure.
