29 reports2 fires
“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.”

“I own a 2015 Kia Forte (VIN: [XXX] ) that experienced complete engine failure. The vehicle had been running normally until it began stalling and sputtering while driving. Shortly after, the engine would only run for 1–2 seconds before shutting off entirely. This exact issue mirrors those documented in previous recalls and class-action lawsuits involving Kia's 2011–2015 models with 2.0L and 2.4L engines. However, despite having the same failure and engine type, my VIN was excluded from the existing recall/warranty extension campaigns. Kia confirmed this is a known issue, but will not cover repairs. This failure occurred at approx. 180,000 miles. Engine failure without warning is a serious safety risk and financial burden. I am filing this complaint so NHTSA can review this issue and evaluate whether additional VINs — like mine — should be included in a broader investigation or recall. A case has been opened with Kia (Case #XXX), and full diagnostic documentation from a certified mechanic is available.”
Service brakes
15 reports2 crashes
“I was driving today and upon braking trying to come to a four way stop, the brake pedal went to the floor with no stopping. My vehicle went through the 4 way stop endangering me and my passengers. The piston blew out where all fluid leaked over the place. This is dangerous.”
Exterior lighting
13 reports
“The contact owns a 2015 Kia Forte. The contact stated that on several occasions while driving at undisclosed speeds, the rear driver's side brake light failed. No warning lights were illuminated. Additionally, the contact stated that she previously replaced the rear driver’s side brake light three times. The vehicle was taken to the dealer where it was diagnosed that the rear driver’s side taillight brake wiring failed and needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 68,000.”
