2015 Kia Forte

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 dealership did not proceed with an engine repair/replacement and indicated that the engine/check-engine-light condition needed to be present. After leaving Kia, the problem became substantially worse. While the vehicle was being driven back, the engine completely lost power and the vehicle became disabled. We had to physically push the vehicle to a safe location. The vehicle is currently available for inspection. Kia later informed us that the vehicle had been reported as a total loss in 2017 and therefore they consider it ineligible for warranty coverage. Regardless of warranty eligibility, my reason for filing this complaint is the serious safety risk created by the sudden loss of propulsion at highway speed. I am requesting that NHTSA document and review this incident as a potential vehicle safety defect

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 indicators of KSDS‑related engine failure and warrant immediate and proper diagnostic evaluation under the settlement terms. The dealership has verbally stated that the issue may be related to **spark plugs and ignition coils**. However, plugs and coils are a **well‑documented secondary symptom** of rod bearing failure, caused by oil contamination and misfires resulting from internal engine damage. This further supports the likelihood of KSDS‑related engine failure. Kia corporate has not referenced documentation of any kind. They have not requested it, indicated they are awaiting it, or provided guidance regarding its submission. Instead, corporate has repeatedly stated that they “must defer to the dealership,” despite the dealership’s failure to perform or submit the required KSDS diagnostic materials.

The contact owns a 2015 Kia Forte. The contact stated that an anti-theft protection software update was performed in 2024. After the update was performed, while driving at various speeds, the vehicle unexpectedly turned off without warning. The transmission was shifted into neutral(N) and restarted to continue driving. The vehicle was reset and self-corrected after being restarted. The vehicle was taken to the dealer, who was unable to determine the cause of the failure. The vehicle was taken to another dealer, Fred Anderson Toyota of Raleigh (9101 Glenwood Ave, Raleigh, NC 27617); and the dealer was unable to diagnose the vehicle. The vehicle had not been repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 85,000.

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.

The contact owns a 2015 Kia Forte. The contact stated that while driving in the fast lane at 70 MPH on the interstate and attempting to move over to the emergency lane, the vehicle stalled. There was no warning light illuminated. The contact received notification of NHTSA Campaign Number: 20V750000 (Engine); after the failure. The vehicle was towed to the local dealer, where it was determined that the vehicle was in LIMP Mode. The vehicle was not repaired. The manufacturer was contacted, but no assistance was provided. The failure mileage was approximately 100,200.

The vehicle began experiencing persistent engine misfires and rough running. Fuel contamination was found in the engine oil, and the spark plugs were fouled with oil and fuel. The catalytic converter has become clogged and failed multiple times due to excess fuel and oil entering the exhaust system. The Kia dealership documented these conditions but refused to perform recall-related engine repairs. Kia Consumer Affairs stated the vehicle does not meet warranty extension guidelines and would not repair the engine. Due to fuel in the oil, misfires, overheating exhaust components, and repeated catalytic converter failure, the vehicle is unsafe to drive and presents a potential fire risk.

The contact owns a 2015 Kia Forte. The contact stated while driving 64 MPH, the vehicle jerked and vibrated, and the vehicle failed to accelerate as intended while depressing the accelerator pedal. The vehicle then stalled. The contact was able to coast to the side of the road. Multiple warning lights were illuminated. The contact was assisted with jumpstarting the vehicle. The contact was able to continue driving; however, the vehicle failed to accelerate as intended while depressing the accelerator pedal. The check engine warning light illuminated, and the battery light illuminated intermittently. The contact was able to pull into a gas station. The contact called his daughter, who went to the gas station and jumpstarted the vehicle. The contact stopped by Auto Zone to have the vehicle diagnosed, where it was diagnosed and DTCs: P2191, P0562, C1101, C1102, C1201, C1204, C1207, C1208, C1210, C1211, C1237, C1260, C1513, C1613, and C1688 were retrieved. In addition, the battery showed codes that fluctuated constantly. The vehicle was taken to the dealer pending an inspection. The vehicle remained at the dealer unrepaired. The contact stated that recently the low oil warning light was illuminated, and the fuel level was low; however, the oil level and fuel level were not low. The ABS, traction control, steering, and tire pressure warning lights were illuminated. In addition, the brake warning light failed to function as intended. The contact replaced the brake lights however, the failure persisted. Upon further investigation, the contact related the failure to NHTSA Campaign Number: 20V750000 (Engine); however, the VIN was not included. The manufacturer was not made aware of the failure. The failure mileage was approximately 168,000.
