2023 KIA K5 Engine Problems

10/25 I was traveling, and my car sudden loss of power, while in traffic.. almost causing accident. 10/28 I was traveling on interstate, and my car sudden loss of power, while in traffic.. almost causing accident. This is ridiculous.. When I hit the gas sometimes, feels like it fluttering and jerking. I’ve reported multiple times over the years and this one having hesitation when driving this car. Manager drove it was concern, mechanic talking about it’s the way the car supposed to be.

My engine line keeps returning regardless of the multiple visits to the service department in attempt to fix recall complications at BONIFACE-HIERS KIA. Today will be the fourth visit for fuel tank and ECM recall related malfunctions.

The contact owns a 2023 Kia K5. The contact stated that upon purchasing the vehicle new and driving off the dealer lot, the message "Radar Sensor Blocked" was displayed. The dealer was informed but no assistance was provided. The vehicle was driven to the residence. The contact stated that another message indicating that a sensor was blocked was displayed, and the check engine warning light was illuminated. The vehicle was taken to the dealer, where it was diagnosed and determined that the engine had imploded. The vehicle was not repaired. The manufacturer was notified of the failure and a case was filed. The manufacturer offered buyback assistance; however, the dealer had not returned the owner’s or the manufacturer’s calls. The failure mileage was approximately 74.

2023 Kia K5 GT1, once at 16k miles and now again at 26k miles, while driving, the dashboard console flickered on me and the car lost complete acceleration and power, fortunately on urban roads or else would have been extremely unsafe and dangerous if high speed, especially since I have a child. Pulled over and turned off vehicle, and turned back on acceleration regained but check engine light remains solid. Took it to dealer at 16k miles and they checked it out and just reset the codes, advised if it happened again to bring it back right away. I am aware of the open recall on this Kia model, but my specific vehicle VIN is not impacted. However, I suspect the sudden power loss issue is the exact same issue. This is an extremely dangerous and unsafe issue with this vehicle, particularly if you have kids or are driving high-speeds...

Component or System Failed: The fuel tank exploded, causing the vehicle to become undrivable. The explosion was so severe that the back seat was completely blown off. The vehicle is currently not in my possession, as it has been with the dealership for over three months. I have photos and proof of the damage, and I am willing to provide them for inspection. How Safety Was Put at Risk: I have a [XXX] son who sits directly above the fuel tank in the back seat. When the explosion occurred, the back of his seat was completely blown off, and had he been in the car at the time, he could have been seriously injured or killed. This was an extremely dangerous defect, and I am deeply concerned that this could happen to other Kia vehicles, putting more lives at risk. Beyond the immediate danger of the explosion, I have been...

One day I was driving and my car began to shake really bad. It doesn’t transition smoothly when switching gears in transmission. Sometimes it doesn’t accelerate and I’d have to floor the gas to get it going. Rough acceleration. Car would even shake in idle sometimes. It has been doing this ever since. One day it’ll shake, the next day it might not. It doesn’t matter if I drive slower or faster, the car still shakes, has rough to no acceleration, and shifts gears roughly. Engine light is on and is reading misfire of cylinder 3.

The contact owns a 2023 Kia K5. The contact stated while making a turn from a complete stop, the check engine warning light and several other unknown warning lights illuminated. The message "A possible condition with your engine control system has been detected" was displayed on the infotainment screen display. The accelerator pedal was depressed, but the vehicle failed to respond as needed. The contact was able to drive back to her nearby residence at a significantly slow speed. The vehicle was towed to the dealer, where the failure could not be replicated. The contact stated that the vehicle operated as needed; however, the failure recurred while making a left turn in a parking lot. The vehicle was towed to the dealer, where it was diagnosed that the throttle body had failed and needed to be replaced. The vehicle was repaired; however, the failure persisted. The contact stated while driving...

Loss of power even hitting the gas. Sputters and does not accelerate. Had spark plugs changed thinking it will resolve the problem and it didn't. Severe safety hazard even needed to get up speed

Received an oil change as part of normal service schedule on a 2023 Kia K5 vehicle purchased August of 2022 (from different dealership). 4 days after this service was conducted, the drain plug in the oil system of the vehicle fell out of my car, therefore draining my vehicle of the oil it needs to operate normally, causing the car to completely stall near my home. I had to pay out of pocket at a nearby Express Oil Change facility to have a new drain plug and oil put into car, after which I immediately brought my vehicle back to this dealership to ascertain what happened. This is the SECOND time this same exact issue has occurred with my vehicle (the first time occurring after an oil change at a different Kia dealership in Charlotte, NC), which I brought to my service advisor's attention prior to them beginning the oil...

The car was 4 months old when I was trying to get home when all of a sudden I noticed all the engine lights started to go out. With a few minutes on the road, the car automatically shut down in the middle of the road. My head almost hit the steering wheel and I was so close to hitting another car. I tried to start the car but it wouldn't start, the engine was making a strange noise and it smelled like burning. I waited 45 minutes on the side of the road and started the car. I drove the car to Kia and the fastest the car will go was 25 miles. When I got to Kia I explained everything that had happened to the car. They did not assure me that the Kia warranty was going to pay for everything and that they were going to investigate...
