2023 Kia Sorento Hybrid engine problems

Filed Oct 5, 2026 · Engine · MD

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 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)

Vehicle suddenly loses power while driving. Engine does not turn on, vehicle will run on battery until battery is dead, then putting the vehicle in park once stopped. Vehicle will not accelerate normally since the engine does not turn on. Only goes 10-20 mph. Lights on the dash come on, prompting to keep car on to charge the battery. No code is found when the vehicle is scanned. Dealerships can't seem to diagnose the issue. This is a safety concern when driving on busy roads or state highways at higher speeds.

Critical Issue: Gasoline leaks into engine. That causes increasing engine oil level significantly and mixed with engine oil. I dropped off me car (mileage: 11731) at Kia Pro in Glendale, CA on 5/1/2025 as soon as I confirmed that engine oil level exceeds the maximum (twice of max) and smelled Gasoline from the dipstick. The service advisor and a tech confirmed that the excessive engine oil level and gasoline smell. However, they refused to repair it under warranty because they don't see any physical leaks and error codes. In addition to that, they told me that the car is not good to drive as is because Gasoline is mixed with engine oil. In my opinion, this can cause critical powertrain failures or possible life-threatening damages if that initiates fire from engine. Car maintenance history: at 6312miles, 1 oil change change at Kia in Alhambra, CA I have attached the service receipt on 5/1 for your reference. That shows that the dealership confirmed the issue but they didn't try to resolve the issue.

I was driving home from work when I felt my car was in a limp like a previous problem I had except this time I had a check engine light come on. I was almost home and I had a check hybrid system pop up on my dash and the car basically stopped driving. Luckily I was on a side street. I had a p0171 code on both of my issues . I had it fixed about a month and half ago the first time but couldn't say what caused the issue.

2023 Kia Sorrento - The engine turned off while driving, leaving me stranded in the middle of a busy road in the first six months of ownership. The vehicle was towed, and the dealer was unable to reproduce it. On 01/12/24, the car leaked all the contents of the coolant system onto my driveway. The vehicle was towed, and the dealer later stated the radiator adapter had a small pebble that appeared to have bent some of the fins. The dealer said it was "external forces," and they are not assuming liability. I firmly believe it was a failure of the radiator adapter and not a tiny pebble that caused the entire system to fail. I write this hoping that if other issues are reported with this vehicle's radiator, it will become a known issue to assist other customers and potentially keep people safe on the roadways. I complained to Kia America, who assumed no liability and stated it was not their problem, although they never requested photographs or the affected part. I am very saddened by the response from the dealer and Kia America during this incident.

At times vehicle hesitates or doesn't responses when accelerator is pushed. Has occurred several times when moving into traffic from a yield lane or stop. Fortunately it hasn't lead to an accident but was very scary. Researching this problem on-line, this has been reported by many Sorento owners. This is an intermittent problem and when vehicle is taken to the dealer they report they can not duplicate problem so nothing is done. By the shear numbers of owners reporting the same issue, something needs to be corrected.
