Vehicle: 2023 kia Sorento, VIN [xxx] , currently 48,000 miles. Vehicle has never been in a collision. Defect: fuel filler door actuator with no emergency release — stranding hazard the fuel filler door actuator fails to release on demand intermittently. When the actuator fails, the door must be pried open with tools or force, which is inconsistent and not always possible. The dealership service advisor has stated that this model is not equipped with any emergency release mechanism for the fuel filler door. With no emergency release, the actuator is the only mechanism by which the fuel door can be opened. Safety implication: an intermittent actuator failure with no backup release mechanism creates a stranding hazard. If the actuator fails when the vehicle is low on fuel — particularly in remote areas, in cold weather, at night, or in emergency situations requiring refueling to reach safety or medical care — the vehicle cannot be refueled and becomes immobilized. This is a single-point-of-failure design on a system required for vehicle operation. The condition has been reported to the dealership and remains unresolved. The vehicle remains within the 5-year / 60,000-mile basic warranty period. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).
Faulty fuel injectors are causing consistent engine misfires and occasionally causing the check engine light to illuminate and for the vehicle to reduce power greatly. This poses a great safety risk to both myself and other drivers on the road because in the event of a large misfire, my vehicle suddenly slows and I have to navigate to the shoulder of the road. A kia dealership has confirmed that the cause of these misfires is due to a faulty fuel injector that begins to work inconsistently above 3000 rpm. This issue began shortly after the vehicle was purchased in 2023, but due to the dealerships inability to replicate the issue it went without correction. In the recent year, this issue has increased greatly and it is now a consistent issue and this is why it was able to be diagnosed now. This is a very common and widespread issue amongst other individual with vehicles with the same engine.
Incident #1: [xxx] the vehicle would not accelerate after coming to a stop at an intersection. The vehicle would not exceed 20 mph with oncoming traffic from both the east and west as I was turning west from a north bound road. On coming traffic was traveling between 45 and 50 mph. I was clearly nearly broadsided. The car displayed flashing lights on the dash as I was attempting to accelerate. Depressing the accelerator did not increase my speed. The car kept at a 20 mph speed for the 1/2 mile I traveled to pull off the road in a safe location, causing traffic to be disrupted until I could pull off the highway I had the car towed to the kia of round rock dealership November 17th. The car remained at kia until December 3rd where they were unable to duplicate the problem. I requested the problem be referred to kia in California. Kia of CA was totally unresponsive when the problem could not be duplicated. Incident #2 [xxx] vehicle failed to respond to accelerate after stopping before attempting to enter a four lane highway. (no traffic was visible. ) the car would not accelerate more than 20 mpr, the speed limit was 55 mph. For the 1. 5 mile trip home, I turned on my hazard lights, kept to the right and flagged traffic around me. The car never exceeded 20 mph. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).
Around 35,000 miles the vehicles fuel pump, relay assembly, and Smart junction box failed and left my wife stranded. Kia took about 7+ days to diagnose and repair.
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.
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.
While I am driving and try to give the car gas to speed up quickly it loses all power and won’t go faster, to speed up I would have to slow down and slowly gain up to the desired speed. It gave me a warning message that I need to park and charge the battery. I don’t have a spot to charge the battery.
When trying to accelerate from a standing stop, there is a one or two second delay, once the accelerator pedal is depressed, before the car moves. Extremely dangerous when pulling out into traffic. I had it back to the dealership to address this problem but they found nothing wrong. I guarantee you , the problem continues to exist.
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.
This is the third time my car has had code p0171 and p0191 pop into the system of the car. I just picked up my car on June 28 and after I left the parking lot it didn't feel right. I had to press the gas pedal a lot harder to get it to move. This is after they replaced the high pressure fuel pump twice within a week and I believe under 200 miles of driving the car. Luckily florida is a pretty flat state so the hill I have between my work and home isn't very steep but I go from 40 mphs down to 30 once I reach the top of it. I'm supposed to be going from florida to north carolina and I don't know how it's supposed to climb the mountains. The first time my car had this problem was April 20 the second time June 17 and the third time was June 26 and the last issue was June 28. The first 3 times it went into limp mode where it won't run the components completely. The last time I had to press the gas pedal all the way so I wouldn't be hit by other vehicles. I only had warning lights the one time but error codes on 3 of the 4 times with last time barely leaving the dealership so I wasn't able to check. It's a safety issue when you have to pray that it gets enough to merge into traffic or to stay ahead of cars where it cause cars to slow down or possibly hit me if they think I would be going faster.
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.
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.
While driving on oregon I-205 south bound received a refill inverter coolant warning. I was on my way to the dealer for other issues and decided to let the dealer fix it. About five miles down the freeway I began to lose power. I was in the center lane and had to move over two lanes of traffic while losing more power. Luckily I made it across with the help of a few understanding drivers and many horn honkers so there was no accident. I turned off the engine and called kia roadside assistance. After about 15 minutes I was connected to a kia assistant who after a few minutes asked if the engine would start and it did. I was then directed to try to make it to the nearest kia dealer which was about 8 miles away. The car went the first seven miles with no problem but then I started to lose power again. I was doing five miles an hour tops when I pulled into weston kia in gresham, ore. I left my car at the dealer. I was called the next day to tell me that a small piece of metal (road debris) had flown through the air intake space below the grill and hit the invertor radiator and that the invertor radiator reservoir was empty causing the car to lose power to save the engine. Luckily they had an invertor radiator in stock and I got my car back six days later. It was not covered by warranty because it was not a manufactures defect. The cost to repair was almost $1100. I question this. I googled this problem and found out that I am not the first person to have this exact problem happen to. If the air intake to the invertor radiator had some protection (1/4 inch mesh) or the invertor radiator were behind the grill this would not of happened. This, in my opinion, is extremely dangerous and would have very easy fix. I asked to keep the old radiator and I have documentation from weston kia covering the repair.
Vehicle loses power from combustion engine and drives only on electric battery. Hybrid system doesn’t engage correctly and vehicle will accelerate extremely slowly after a delay and will only achieve roughly 30 mph with accelerator fully pressed. This vehicle has been sent to the dealer multiple times and they have recreated the problem. However even after parts being replaced and connections being replaced the problem persists. Vehicle can be inspected anytime. My family has been in several near collisions with oncoming traffic due to the vehicle moving after a delay and then at a much slower than expected pace. Pulling out in to traffic is nearly impossible when the vehicle malfunctions. It has also depleted the entire battery and left us motionless on the side of the road multiple times. Due to the problem being intermittent and not reliably duplicated a service technician was given permission to use the vehicle to commute to and from work for a time. This allowed him to experience the issue in person. The vehicle has been inspected multiple times by the dealers service department and they have been working with engineers from the manufacturer. When this problem occurs there typically is not a warning light or a code stored. They believe it is a faulty connection. This issue will cause an accident in the future if not resolved. The manufacturer has not been able to determine what is causing the issue. They also have not been concerned with our safety and have released the vehicle back to us 3 times stating that it is fixed yet the problem persists.
I was driving down the highway on cruise control going 67 on a 65. The car started revving up and then proceeded to go faster. I turned off the cruise control but its continued to speed up. I stomped on the brake 4 or 5 times with no effect. I rammed into the back of a bus at 110 mph.
