Electrical issues since 44K miles I’m at 50 K miles. I’ve complained multiple times and they kept saying electrician wasn’t available. Then they lie about it being a waitlist for a loaner car. All the lights on the dashboard goes on and all the dealership couldn’t diagnose the problem. The second time the check engine lights went out the back up camera. They said it was the back up camera the backup camera was replaced the backup camera now messes up all the time and does not cut on when backing up randomly cut on when driving Kia issue was flashing lights, but they decided to worry about the check engine light, which was the careless converter, they fixed the careless converter And didn’t fix the flashing lights problem. They tried to say the car electrical reason was physical damage, which was false and now the electrical problems are getting worse the gear shifter license to work on the PRND the right brake light in the front and back goes in and out. I don’t know what the mileage is while driving I got a ticket from the cops because of that, the mileage randomly changes and I never know how much gas is in the car when I put in gas.

My safety system keeps malfunctioning. I am unable to use safety features, blinkers, hazards and gauges of speed, gas and rpm go to zero. I have taken my car several time to the Kia dealership in Arlington Texas and they keep giving me the run around with my concern. They say that don't have codes that validate a problem. I have shown them video and pictures of what happens and they refuse to help me. My complete dash will light up and all my warning signs are in and blinking and bell is going off. Systems of failure had been taking place for a year now and I don't know what else to do. I had a recall done on my new car at the location and since then I e been dealing with this safety issue.

Dec 13, 2023Lane Departure

My Lane keep assist in my 2023 Kia Forte GT Line does not function as intended. It frequently pulls me into the lane with oncoming traffic as well as the lanes next to me. I'm unable to pinpoint when, where or why but I do know it typically happen in one spot of my town but everywhere else seems random. It's incredibly dangerous.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2023 Kia Forte Koup verdict →
