2021 Kia K5

Vehicle experienced a severe engine misfire (P0302), rough running, and loss of power while driving. Dealership confirmed the Purge Control / PCV valve failed (replaced under Recall SC356 / 25V-794), but charged out-of-pocket for the Cylinder 2 ignition coil that failed as a direct result of the PCV valve failure. The Dealership replaced the Purge Control/PCV valve at this time - the recall was not resolved until this time - I wasn't even aware of this recall until this incident. This ocurred on XXX and as a result I was stranded 1500 miles from home in [XXX] (I live in [XXX] and was driving the vehicle to my son at the University of XXX in [XXX]. The car was running fine until I stopped briefly in [XXX] and when I started the car, the engine light came on and the car's engine started sputtering and losing power as I was driving. Due to the fact that I was not in the vicinity of any Kia Dealerships or any open mechanics as it was Labor Day, I somehow managed to drive the car all the way to [XXX] as this was the closest dealership (over 120 miles away from where I was when the engine light came on). Once I arrived in [XXX], I checked into a hotel. I then attempted to drive to the nearest Kia Dealership the following morning at approximately 6:45 am and the engine light started flashing. I knew that this meant I was not able to safely drive the car even the additional 5 miles to the dealership so I pulled over and called Kia Roadside assistance and the dealership.

I originally got my car 2023 from Carmax I took it in to Kia dealership to get my recalls done they kept my car for over 6 days without fixing it when I arrived I was showed a photo saying it’s after market parts on this vehicle and we can’t touch it also they stated my vehicle was dangerous to drive so I asked for documentation that my vehicle was denied and they refused also I called Kia cooperate to file a complaint to get proper documentation that my vehicle was denied they told me it was denied as well and said they can’t give me paperwork to state anything

The vehicle experiences severe stalling and loss of power while driving. When attempting to accelerate, the vehicle hesitates, shakes violently, and will not accelerate beyond approximately 10–20 mph. The vehicle then stalls completely and shuts off. These failures occur both after the vehicle has been parked and while actively driving. When placed in drive, the vehicle shakes aggressively and stalls. The check engine light is illuminated. The stalling has occurred multiple times in the middle of freeway traffic, creating an extreme safety hazard. My child has been in the vehicle during every occurrence. On one occasion, the vehicle shut off completely while on the freeway, placing our lives at risk and nearly resulting in a serious collision. This issue is unpredictable, persistent, and prevents safe operation of the vehicle. The vehicle has been inspected and worked on by Southwest Kia and A-Z Auto, but the defect continues to occur. I believe this is a manufacturing or design defect related to the engine or powertrain that poses a serious safety risk and should be investigated to determine whether other vehicles are affected.

Within three days of purchase, the vehicle experienced a fuel system failure requiring the gas tank to be replaced. Shortly afterward, the check-engine light illuminated, indicating additional engine or emissions problems. The failures occurred without warning and made the vehicle unsafe to drive. The engine warning has continued to appear, suggesting a recurring or unresolved malfunction. The defects create risks including fuel leakage, stalling, engine shutdown, and potential fire hazard. The safety of the driver and others on the road is put at risk because the vehicle may fail while in motion. The problem appeared immediately after purchase and continues to recur. The dealer was notified but refused to diagnose or repair the vehicle further. No manufacturer inspection has occurred because the dealership declined to provide service. The warning light first appeared within the first week of ownership and has remained intermittent. The vehicle shows signs of unstable engine operation and ongoing system malfunction. The issue has been observed by the dealer, but they declined to perform proper diagnostics or repair. The defects are persistent and pose ongoing safety concerns.
