While driving hybrid battery depletes and car stops accelerating. With pedal to the floor, it may get to 60 MPH, other times 15 MPH. Car doesn't sound great while this is happening. 3/4 times an error showed up stating "Check Hybrid System-Stop Safely". The 4th time the error didn't appear , but was driving on hilly road where battery charged when it was going down a hill. The problem occurred on back roads and Highways. It is VERY unsafe when you suddenly can't accelerate. The car was towed to a kia dealer twice. 1st time I was told it was "bad gas." $1,500 later, it happened again. The 3rd time I had it again towed to a Kia Dealer. 6 weeks later, I was told they couldn't find anything wrong, and Kia released the car. 1 week later, it happened again on the Highway. Dates of occurrence: November 17, 2025 November 25, 2025 December 11, 2025 February 9, 2026 (car was at the dealer from Dec 11-January 29th)

The contact owns a 2023 Kia Sorento. The contact stated that while driving approximately 40 MPH on several occasions, the vehicle stalled after the battery became drained. The vehicle was able to restart each time after waiting for the battery to recharge. The vehicle was taken to two different dealers on three occasions. During the first two visits, the dealer was unable to duplicate the failure. On the third visit, the failure was duplicated, but the dealer was unable to provide a cause for the failure. During a visit to the dealer, the vehicle stalled while a mechanic was driving it, and the vehicle was towed back to the dealer. The manufacturer was not notified of the failure. The failure mileage was 25,000.

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.

While slowing from cruising speed to around 5 MPH, give or take, and pressing on the accelerator, the vehicle will not respond/accelerate for up to 1 second. This is dangerous because you don't know when the vehicle will respond and if you'll have the acceleration. My assumption is this is a symptom of the hybrid system trying to determine the best mode of propulsion - gas, electric only or a combination of both. We've taken it to the dealer and we were told "this is how hybrid systems work." We've owned Toyota hybrid systems and we know this is not normal. Kia/Hyundai should reprogram the hybrid system to that it responds with no delay, even if it means the fuel milage suffers as a result.

Faulty Oil filter placed in Vehicle during Oil Change at Dealership. On November 4, 2023 vehicle was taken into Rick Case Kia located at 3190 Satellite Blvd, Duluth, GA 30096. The oil was changed and vehicle driven approximately 5 miles home that afternoon, The following morning the vehicle was driven approximately 25 miles to Cobb Hospital. At no time during the ride did I note warning signals that something was wrong. At lunch I went to my car and started the vehicle and it alarmed with Engine and Oil lights. The vehicle was making a knocking noise. They added oil back to the engine and stated it was OK to drive. The manager of the dealership stated that this has happened several times.
