My car loses power when I use the horn. It happens while parked with the engine on and in traffic. Initially, I thought it was faulty electrical problem because there were 3 active recalls needing to be fixed. I recently took my vehicle to a certified kia service center to get the recalls taken care of and additonally, had the a/c compressor, struts, and a belt replaced. I also described the issue of engine power loss when I use the horn with service tech and attempted to demonstrate. However, my car didn't duplicate the issue. I'm not sure if the techs tested it thoroughly during the days it was being serviced. The final detailed bill states that the car wouldn't duplicate the issue. I'm currently satisfied with the fixed recalls, a/c, belt, and other minor repairs. I'm highly concerned and frustrated that I'm still experiencing engine, acceleration, rpm, and a/c failure whenever I need to use my horn. A couple of days ago while in traffic, I had to blow the horn because a distracted driver nearly side swiped me. As a result, my car loss power. I couldn't accelerate and the transmission wouldn't shift. I ended up doing around 30mph until I made it to a safe destination. I called for help, but after I turned the car off and back on, it was as if it never happened. I'm furious about it because the distracted driver proceeded to tailgate and intimidate me out of anger. Lastly, it was not professional or caring to be laughed at when I voiced this problem at the service center. I need help and answers before something more terrible happens. The number of engine and electrical complaints are startling. I'm hoping that my issue will be taken seriously and looked into. I'm not comfortable driving my car.
