2023 Kia Sportage Fuel system Problems

I was driving down the highway at the posted 70mph limit in medium traffic. The car started to sputter and wouldn't accelerate. The car started to decelerate and cars coming from behind had to quickly swerve to avoid me. The cab then filled with the strong smell of gasoline and I became light headed. The car reduced to around 10mph and I pulled off the highway into a gas station and waited for a tow truck. We towed the vehicle to a Kia dealership and they claimed to have fixed it. A similar circumstance has occured 3 more times since that first issue. After each time, Kia has claimed to have fixed the issue.

Purchased the vehicle 2nd hand January 29th 2025. Since then she has been in and out of multiple shops including Kia. Check engine light, loss of power on fwy, shifting/brake changes from a stop. From jerking, lunging, studder, taking off fast, not wanting to go at all. I was on these dips that I encounter almost daily and the collision warning went off. There wasnt anything in front of me. 2 weeks later I was cut off and had to swerve to avoid. Collision warning DID NOT go off. Driving on the fwy and the gas pedal pulled away from my foot as if it was accelerating. Kia has done a hard carbon, changed all fuel injectors. Last time they stated there was a factory defect with the rotors, changed all 4 rotors. Still she drives like this. Carmax, Kia and Daniels Tires NO ONE can tell me what is wrong! I have driven a 2024 same make and model and the car drove beautifully. Something is wrong with my particular vehicle. This is becoming frustrating. Please help. I drive often, I hike a lot. We are always on winding roads. I can't afford to sell it as I still owe. I love the vehicle, aside from this, like I'm just waiting for disaster to occur. Miles started at 14.5k and it's now 33k. Speeds have been anywhere from a complete stop to go and fwy speeds of 55 to 80.

I had my vehicle take to Coughlin Kia in Dublin Ohio on [XXX] and got my vehicle back on [XXX]. The service center at Coughlin claimed I had bad gas, they took it upon themselves to approve services I did not approve of. When I got my vehicle back on [XXX] I found wires under my hood and caps left under my hood as well. Then on 4/26/24 my vehicle started having problems, my vehicle would have the RPMS jumping from 500 to 1,000 while sitting in park and driving. Not once did I ever mess with my vehicle under the hood. I notice this problem getting worse as the days went on. On 4/23 my vehicle wasn't getting any better, the engine was shaking while sitting in park and it was shaking the whole car. On [XXX] on my way back from a lunch break my car stalled out and stopped in the middle of traffic. I called Great Lakes dealership in Columbus Ohio, and have my vehicle taken there. My vehicle declined in speed while moving on a high speed highway. Putting my safety and my families safety at risk. Kia won't own up to any mistakes, they claim this as bad fuel and I have been putting high octane gas in my vehicle. I do believe my vehicle was messed with by someone at the Coughlin Dealership and now I'm facing safety issues I can't drive my vehicle because its unsafe and my vehicle has only 23,600 miles on it. I'm highly disappointed I reached out to the director of operations Michele Cameron and she refuses to respond back to me and return my phone calls. I can't get anyone from Kia Corporation to respond back to me. I was told by Kia Connect that they wouldn't provide me a tow truck last night when my vehicle was on the side of a busy highway. I have warranty on my vehicle and I get free tows and was told they couldn't provide one. No safety vehicle would sit with us on the highway to make sure we were safe.

Leased NEW Kia Sportage on 1/1/22 Went in for oil change on 11/11/22 3 hrs later told a "forced" update "burned" out the computer and car was not driveable On 11/30/22 was driving to work on LI expressway, car shut down without warning while I was driving, smelled something burning, called 911, car towed to dealer. Told it was defective fuel injector. 1/29/23 I reported brakes grinding and vibration sound coming from engine, RPM's rev up but car doesn't accelerate. Brakes needed to be cut. Was told since there was no "code" nothing could be done about engine sound/rpm increasing. Car was in for service 3 times because of this issue. 9/10/23 car shut down while I was driving without warning and gas smell in car was nauseating. Car would briefly start & shut down. Car towed to dealer. I have reached out to Kia Corporate numerous times expressing I am afraid to drive the car, the car is dangerous and my life and the lives of others at risk. When car shuts down, ther is NO warning, it just STOPS. I have had nightmares and lost sleep. I travel on highways & busy roads everyday. Kia wanted me to sign waiver releasing them of everything in lieu of 3 months lease payments. Expressed my life & lives of others are worth more than 3 payments. Car has had 2 recalls on top of these issues. I have reached out for help and have been ignored. 9/12/23 told by KIA corporate it would take 2 weeks to escalate my complaint. Car is currently at dealership. PLEASE HELP!

This is a new vehicle with only 1200 miles on it. I was told by Gunther Kia in Ft. Lauderdale that my car could be serviced at any Kia dealership. The car has developed a fuel injection problem. When in heavy traffic with a lot of stop/go, the fuel injection does not seem able to keep up with the aceleration and deceleration required. The car hesitates. As the trip progresses the hesitation progresses. I was trying to enter traffic on the interstate and nearly had a collision because the car would not accelerate quick enough.

Please answer these questions using my words What component or system failed or malfunctioned, and is it available for inspection upon request? I was unable to accelerate the gas pedal after the car started bouncing up and down and smelling mid driving. How was your safety or the safety of others put at risk? I was on a major road at the time this occurred. Thankfully the time of day was in my side. If this was a few hours later there would have been a collision as I was in a main lane and had to veer to a turning lane. I am frightened every time I’m in the car now. Has the problem been reproduced or confirmed by a dealer or independent service center? The dealer ship has confirmed. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No Just the dealership. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No, the warning came on after it happened.

I was projected into a stone wall and knew I was going to crash . I crashed into the wall,all my airbags were deployed and the car smelled like smoke. My accelerator got stuck and was sideways .I was unable to get out of the car from inside but a Good Samaritan had opened the door from the outside and I crawled under the airbags and got out .

The car is currently in the shop at Jim Shorkey Gainesville Kia and is available for inspection. They have contacted me to tell me the transmission/engine failed. I was driving on interstate when I suddenly lost the ability to accelerate and was forced to get off of the highway. After coming to a complete stop I pressed on the gas pedal but the car would still not accelerate. I tried putting into park and back into drive and that did not work. I tried putting it into manual mode and it did go forward but every gear change was loud, jerky, and rough. I was able to make to my next complete stop in a left turning lane to cross a two lane busy highway that is coming downhill towards me at an intersection that does not have a traffic signal. However the car was stuck in gear 5. I was the first car in line. At this point I put other cars in danger as they swerved back into the high way to get around me into the intersection to make that left turn across busy highway. I turned the car completely off and after a minute turned it back on. I put in drive, waited until I couldn't see any cars coming down the hill and I pressed the gas pedal to test. It jerked forward and I managed to get across the highway as it shifted into the second gear it jerked violently and made a loud popping noise and there after every single gear change was loud and jerky. Thank God I did not lose the ability to accelerate in that left turn because those cars are coming at 70+ miles per hour Down that hill or my family would have been t-boned on their passenger side. I am also lucky that I was able to get off the nearest exit when they problem originally happened as I was going downhill on the interstate and the next exit was very close so my momentum got me there. I lost the ability to control the vehicle as I ordinarily would putting myself, my family, and other motorists in danger had we not been able to get off on the exit or make it through that left turn.
