“While driving my 2015 Kia Forte5 at approximately 80 mph on GA-400, I was traveling in the far-left lane when the vehicle suddenly and unexpectedly lost acceleration and engine power. Pressing the accelerator produced little to no response. There was no gradual reduction in speed or sufficient warning that the vehicle was about to lose propulsion. Because I was in the far-left lane, I had to maneuver across approximately four lanes of highway traffic to reach the shoulder. Fortunately, this occurred at night when traffic was relatively light, allowing me to get the vehicle to safety. GA-400 normally carries very heavy traffic during the daytime, and I believe the same sudden loss of propulsion under those conditions could have resulted in a serious collision because the driver may have no safe way to cross multiple lanes while rapidly losing speed. After the initial incident, I was able to drive approximately five minutes to my brother’s house. An independent mechanic inspected the vehicle, and the following day we brought it to an authorized Kia dealership and explained the loss-of-power condition. At that time, the engine had not yet completely failed. The…”

“respectfully submit this correspondence to request formal assistance regarding my 2015 Kia Forte EX, a vehicle covered under the class settlement. The vehicle is exhibiting severe symptoms consistent with KSDS‑related engine failure, yet the required diagnostic protocol has not been completed by the servicing dealership. The KSDS software update was performed in May 2022, and the vehicle currently has only 92,000 miles on the odometer, placing it well within the settlement’s mileage parameters. Despite this, the dealership has failed to follow KSDS procedures and has not produced any written documentation of its findings. All communication with the dealership has occurred exclusively by telephone. Despite repeated attempts to obtain information, I have not received a diagnostic sheet, video recording, code report, KSDS documentation, or any written summary of the vehicle’s condition. All statements provided to me have been verbal and inconsistent. My **primary symptoms** include: - Persistent and worsening **engine ticking** - **Burning excessive amounts of oil** - Activation of **limp mode** - A **flashing check engine light** These symptoms align with known…”

“The car is jerking while driving. It's caused the car to overheat. It's hard to start up and usually stalls out. It has stalled out while driving almost causing a accident. The engine light came on. I took it for a diagnostic and it was code P0172 for high pressure fuel pump. Before the incident date it was already hard to start prior to the engine light coming on. It sometimes causes smoke to come out of the exhaust. There was also smoke from under the hood in the engine compartment and as soon as I put gas in the car it runs out very quickly. This issue could have caused and accident or even a fire. It's unsafe to drive and from other reviews I've seen several other Kia drivers have experienced issues with this same faulty part, which is expensive to fix.”
