2016 Kia Forte Koup problems

“Im getting denied dued to engine failure but whoever had the vehicle before didn't follow up with the ksds update, I just purchased the vehicle on June 30th,2026, I need this fixed ASAP because I still owe on this car.”

“The Headlights and ALL exterior lights FLICKER or TURN OFF ENTIRELY while driving, especially when touching the Multi-Function Turn Signal Stalk to signal a turn. This can and HAS happened when the Headlights are switched on any mode: MARKER LIGHTS, HEADLIGHTS, or AUTO. I can be driving, Headlights are on AUTO - suddenly - ALL HEADLIGHTS/EXTERIOR LIGHTS FLICKER OR TURN OFF. I have to quickly touch the Multi-Function Stalk or switch it from AUTO to HEADLIGHTS to keep the lights on. I then have to be careful when using the same Stalk to signal turns or it may cause the lights to flicker or turn off entirely AGAIN. THIS ISSUE CAN OCCUR EVERY DAY IF I'M NOT VERY DELICATE WITH THE MULTI-FUNCTION STALK. SOMETIMES, IT FLICKERS/TURNS OFF NO MATTER WHAT & I HAVE TO SWITCH THE LIGHTS FROM AUTO TO HEADLIGHTS OR VICE-VERSA TO ENSURE HEADLIGHTS STAY ON. THIS ISSUE HAS EVEN HAPPENED WHEN I DIDN'T TOUCH THE STALK AT ALL & I WAS DRIVING ON A DARK, RURAL HIGHWAY. LIGHTS OUT! THIS IS A DANGEROUS ISSUE THAT CAN INCREASE THE RISK OF A CRASH. PLEASE INVESTIGATE, THANK YOU. I plan on having this issue fixed ASAP at my expense, which I hope won't be too expensive. $$$”

“1. NHTSA Safety Complaint Draft Vehicle Info: Make: Kia Model: Forte5 SX Year: 2016 VIN: [XXX] Engine: 1.6L GDI (G4FJ Nu engine) Issue: This vehicle uses the 1.6L GDI Nu engine (engine code G4FJ), which is the same engine involved in Kia’s engine defect recalls and class action settlements related to connecting rod bearing failure and engine seizure risks. However, Kia is refusing to provide the Knock Sensor Detection System (KSDS) update, and no internal campaigns or recalls are listed for my VIN despite the identical mechanical risk. I purchased the vehicle in 2017 and was unaware of the extended warranty and safety campaigns until now. I am experiencing symptoms of rough idle and pre-knock concerns, and yet Kia and my local dealership are unwilling to escalate my case or even verify warranty eligibility. This defect poses a risk of sudden engine failure and should be addressed under expanded recall coverage. I am requesting NHTSA investigate inclusion of later-production 2016 vehicles like mine, which clearly share the same defective power train.”

“I am filing a formal complaint regarding serious safety and mechanical problems with my vehicle. The brakes do not function properly and I have to add brake fluid every few days, which indicates a possible leak or brake system failure. This creates an extremely dangerous driving condition. The vehicle also has electrical problems, including malfunctioning lights. The engine has lost power, making it unsafe to drive, especially in traffic or on highways. In addition, the airbag warning light is on, which means the airbag system may not deploy in a crash, putting me at risk of serious injury or death. These problems have made the vehicle unreliable and unsafe to operate. I am requesting that these issues be inspected and repaired immediately at no cost to me, or that the vehicle be replaced or refunded under warranty or consumer protection laws. I am concerned for my safety and the safety of others, and I expect this matter to be handled urgently.”

“The contact owned a 2016 Kia Forte. The contact stated that while decelerating due to traffic, the vehicle was struck in the rear end and pushed approximately a few feet, causing the vehicle's front end to crash into the rear of the vehicle in front. No warning lights illuminated. No air bags deployed. The contact stated that due to the impact of the crash, she had fallen unconscious. A police report was filed. The contact sought medical attention for bruises and head damage. The vehicle was towed to the local tow lot, where it remains, and was declared a total loss by the insurance provider. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The contact related the failure to NHTSA Campaign Number: 22V031000 (Airbags) however, the VIN was not included. The manufacturer was made aware of the failure. The failure mileage was unknown.”

“Headlights shut off entirely multiple times when switching to high beams on dark road, almost causing an accident. Multi-function switch failing the exact way the Sorento switches are failing, confirmed by mechanic. This is a severe hazard when driving at night. There was no warning whatsoever.”
