“Car goes into limp mode or cuts power when trying to accelerate. Refuses to shift or will shift down and revs highers rpms then necessary, especially at any incline. Started around 70k miles and got worse when brought in for other recalls.”

“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.

“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.”

“The contact owns a 2015 Kia Forte. The contact stated that the vehicle failed to start intermittently. The vehicle was taken to a certified mechanic and was repaired; however, the failure recurred, and the vehicle was taken back to the certified mechanic, and an unknown repair was completed. The contact was unsure of the repair that was completed. After having the vehicle repaired a second time, while attempting to accelerate, the instrument panel was flashing the check engine and the oil light warning lights. The vehicle decelerated, and there was black smoke coming from the exhaust pipe. The contact stated that the vehicle lost motive power shortly afterwards. The failure had occurred three times. The vehicle was towed to a certified mechanic twice. The mechanic repaired the knock sensor and drained and replaced the engine oil and cleared the codes. The failure reoccurred, and the vehicle was taken to the mechanic, and was then towed to the dealer, who diagnosed the vehicle and determined that the knock sensor had failed. The knock sensor was replaced; however, the failure recurred. The contact was informed that the engine needed to be replaced. The engine…”
