2023 Kia Sorento Hybrid problems

“On [XXX] at [XXX], while driving northbound on [XXX] in Montgomery County, MD, just before Exit [XXX] (about 10-15 minutes after leaving home), the engine overheat warning came on. My child was in the vehicle with me. I pulled over to the shoulder briefly. Thinking it might be a temporary error, I resumed driving, but the same overheat warning came back almost immediately, so I pulled into a nearby restaurant parking lot and stopped the vehicle. I checked under the hood and found the coolant reservoir nearly empty. Because the vehicle was not safe to drive, I had it towed that evening to King Kia (Gaithersburg, MD). Next day on Monday morning, the dealer diagnosed that the Exhaust Heat Recovery System (EHRS) had failed internally, causing coolant to leak into the exhaust system, and recommended replacing the EHRS at a cost of $1,475.55. The vehicle has approximately 61,000 miles, just past the 60,000-mile basic warranty, so the dealer stated it is not covered. This failure caused sudden engine overheating while driving on a highway with a child on board, creating a serious risk of engine damage, stalling, and a crash. Kia Customer Care case number: [XXX].”

“While driving on September 15, 2025, the vehicle displayed a loud beeping and the warning message “Check Hybrid System. Stop Safely.” The vehicle restarted about an hour later, but the combustion engine ran very rough. The Kia dealer inspected it but reported no stored error codes. On September 23, 2025, the vehicle suddenly lost power while driving. It appeared to operate only on electric at low speed, then died completely in the roadway. The vehicle would not power down until the start/stop button was held. It required a tow back to the dealer. Prior to the first incident, a faint electrical smoldering odor was present. The vehicle remains at the Kia dealer for evaluation. This is a serious safety concern because the vehicle experienced sudden loss of motive power and stalling in traffic, which put both myself and others at risk.”

“During normal operation the vehicle will randomly decelerate (no brake lights). This has happened on the highway and on city streets. I repeat on the highway this vehicle will go from 75mph to 40mph with no lights or warnings. The issue happened with my wife and child in the car and I was able to replicate the issue. I refuse to put my family in the car at this point. The Dealership says they cannot replicate the issue but is also lying about driving it diagnostically. The issue is video documented on two occasions. Since vehicle is under warranty it was brought to the dealership both times and have had zero resolution. During its last visit I was without the car for a month. I Contacted KIA corporate who denied a buy back. This vehicle will undoubtedly kill or injure my family or more if driven. I have been responsible and not done so to protect the public. But I need the car. Car is available for inspection at anytime. Videos available upon request.”

“The contact owns a 2023 Kia Sorento. The contact stated that while stopped at a light or making a left or right turn, while depressing the accelerator pedal, the vehicle failed to respond. The contact stated that seconds later, the vehicle responded, and the vehicle hesitated and moved forward independently. The contact stated that during the failure, there was a vibration coming from the rear passenger’s side wheel, and the vehicle lost motive power while driving. A dealer was contacted. The vehicle was taken to the dealer to be diagnosed; however, the diagnostic result was unknown. The battery and all four tires were replaced, and the vehicle was repaired. The contact stated that the failures had occurred several times over the past two years. The manufacturer was notified of the failures and stated that the VIN was not under recall. The approximate failure mileage was 95,000.”

“I was driving down the highway when my vehicle shut off with no warning and the parking break engaged. I was stuck in the travel lane with cars flying by me going 50 plus MPH. My vehicle has 7000 miles on it. According to KIA the hybrid battery failed and they don’t know why. KIA has been no help and as far as I know they are not looking into this issue. Upon further research there has been multiple instances where this hybrid model has just shut down while the vehicle is moving and KIA has been unable to resolve the issue. Myself and my children could have been severely injured or killed. They need to get to the bottom of what is causing these hybrid batteries to fail on brand new vehicles.”

“The sub roof exploded while on the freeway and all the glass shattered like rain onto the fabric underneath. We pulled over on the side of the freeway and are waiting for a tow. We didn't see any large objects fall or fly towards the car. It sounded like a huge explosion then left a big whole.”
