2014 KIA Forte problems

POWER TRAIN

The systems affected appear to be engine, powertrain, and vehicle speed control. My 2014 Kia Forte, VIN [XXX] has approximately 118,000 miles. Since purchase in November2025 from Wondries Toyota, the vehicle has had repeated high RPM, poor acceleration, and loss of power when entering freeway on-ramps and driving uphill. It struggles to accelerate while merging into faster traffic, creating a safety risk as vehicles behind approach at higher speeds. Two different mechanics verbally advised that there may be an oil leak or oil consumption issue affecting the catalytic converter. I replaced the catalytic converter a couple months ago, but it became clogged again and the power loss continues. The vehicle is available for inspection. The problem has not been inspected by the manufacturer yet, and I don’t have a written diagnostic report at this time. There was no crash, fire, injury, or fatality, and no police report. Warning lights are unknown. The exact incident date is approximate. The issue has been ongoing since after purchase and occurs multiple times, especially during freeway merging and uphill driving. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

ELECTRICAL SYSTEM

I have currently been avoiding driving my car because it goes in limp mode when I’m stopped at red lights I smell oil burning sometimes ive seen small amounts of smoke coming from the engine as well as just receiving an oil change less than a month ago and it already being bad , I checked the mail the other day and i received a recall letter from Kia stating my car needs to be serviced and that I can take it in for a free engine test and inspection free of cost as well as a system update free of cost , I schedule an appointment today for 11 I was told it will take half a day I receive a text to pick it back up 1 hour later I ask if an engine test was also done i received no response so I came in and was told that I would have to pay 270 for a diagnosis despite the engine inspection being different they refused to do one stating the previous owners warranty is up so the system update was done without any inspection or test to see if the damage was already which it is based off the state of my car , when trying to leave my car was not starting up and when it finally did it went into limp mode completely and wouldn’t drive at that point I reach out to Kia costumer care center and they let me know that I should have gotten a inspection free of charge along side the update and to go somewhere else online also states regardless of warranty all recalls must be addressed if problems persist regardless of past service or owner , they also cleared my recall and listed it as repaired and it was not Kia corporate shows it is still an open recall as well . I also received a Kia multi point inspection that was not at all fully performed it is 1/4 fill out .

UNKNOWN OR OTHER

My vehicle was leaking fluid, so I took it in and discovered that my vehicle’s ABS module failed in what was described to me as an “unusual way” at both the initial garage where I took it and, later, to the dealership, which was the only place that could do the actual repair. Some research showed that the failure matched the way this component failed in Kia and Hyundais that were recalled for this issue, which the dealership acknowledged. But my specific car wasn’t included in the recall, so I had to pay thousands of dollars out of pocket to repair it. Since then, I’ve been waiting for the recall to expand to include my vehicle so I could be reimbursed, because it seems very unlikely my vehicle didn’t get the same flawed system that was recalled in the other Kias and Hyundais. I’m told submitting this could help.

ENGINE

Engine developed a “ticking” sound, oil consumption has increased and vehicle will periodically stall at low speeds when driving especially towards the end of the oil change interval. All periodic maintenance has been performed since I have owned the car. Previous owner indicated the same. This has the 1.8l engine which I understand can exhibit these same problems but thus far has been at least partially left out of any recalls although that isn’t entirely clear.

UNKNOWN OR OTHER

I had a brake system failure of some sort happen today. My life and the lives of many others were put in extreme danger. I was driving at about 40 MPH and was approaching a red light. I pressed down on my brake pedal to begin slowing down, but I got absolutely nothing in response. Out of panic, I pumped my brake pedal. This again, did not slow me down at all and my brake pedal fell to the floor then went stiff. After it fell to the floor and went stiff, I pumped and pressed down on it again with all of my strength, at which point I was able to get a very small response and slow myself down to a stop. This is the 4th time this has happened to me in the past 45 days, I took the car to a local AAA shop but they found zero issues with my braking system (cylinders, fluid, lines, drums, pads, etc.) There has never been a warning light of any kind related to my brakes, wheels, etc. The Vehicle had a brake line recall several years ago, a certified dealer serviced the recall and ensured everything was safe with the vehicle and braking system.
