    Engine code came on, one interior headlamp works when it wants to, climate control module is bad it has cause the relay to blow and the resistor to go out. The air turns up on the control module by itself and then your ac just stops working and then starts again as it chooses. All of these are electrical issue as stated in MANY OTHER reports. And electrical issue is unsafe it can cause fire at anytime, my car is new 2021 Kia k5 Lxs, 60k miles and now who knows when the car is going to catch fire while my baby is strapped in a car seat and no AC . RECALL before lives are took from heat stroke or possible fire. To be “luxury” it’s sad I just paid my 3rd car payment and now I can’t even drive my car. Over 100 reports on this same problem and y’all do nothing. Kia is maybe at 70k sells a year now meanwhile Toyota and other are at 300k. When my baby is insured do to this crack head wiring system I will sue someone this is ridiculous.

    Rotors warp after only a few months. I’ve replaced them multiple times since I got my vehicle 2 1/2yrs ago. Steering wheel will shake really bad while braking and that’s how I know I need new rotors again. Many people with this year/make/model have had the same issue. It’s definitely a safety issue that needs to be addressed.

    The fuse pin melted into the wire harness. Kia is not recognizing this as a safety issue although they acknowledge that the melting pin could cause a fire.

    I bought my Kia k5, my blower motor went out upon inspection the problem was a multilink fuse for the blower motor. The fuse is burning the wiring harness, I believe this to be a fire hazard. After some research I believe this to be a common issue with this particular car.

    Underbody dust panels have torn off of mounting bolts without any clear cause of damage, main front panel and right passenger side panel. Loose panels could have fallen off on highway. Only indication they came loose was when they began flapping in air flow from driving.

    When I was driving I heard big boom sounds in my backseat which ended up being my fuel tank which expanded and raised the back seat. It slowly got worse impacting my car’s fuel sensor and the tank expanded more and more I drove.

    My Gas tank has Expanded in Size and has made my back seat Pop up and gas leaking when it does because the ring around the Gas pump would Loosen Up. I noticed this issue first around April of Last year when it got Warmer. I would have horrible fuel efficiency, and my gas hand acted very Crazy. A few times it felt like I had been hit by a car from the Back a large Boom! When I am have a problem m car would slow down on highway and wouldn’t Accelerate at all. For past few months it started again. But what made me take it in was a louder bang followed by seat not only popping up but not being able to close. Service center kept my car said it was not safe to drive , I have been without transportation going on 3 weeks.
