Mar 2025

Driver power window regulator stopped working. It is available for inspection upon request. My safety is at risk because it can hinder my ability to exit the car in an emergency. In addition, it is exposing the car's interior and possibly interior electrical parts to the weather elements, and potentially leaving me vulnerable to theft or intrusion. The problem was intermittent at first, and I reported it to the dealer, but at that time of service, they were unable to reproduce the failure. The service department told me this is a fairly common problem with my model of car. The component has not been inspected by Kia, the police, insurance representatives, or others. The symptoms were intermittent at first prior to the total failure. The full failure happened at 101,500 miles, which is past the 100,000 mile warranty expiration.

The plugs for the engine cooling fan and wiring harness were damaged from overheating. No fuses blew, plugs were melted and wiring was discolored from overheating. Estimate for repair was: Parts (cooling fan assembly, and wiring harness)- $2430.19 plus tax, Labor 8hrs @ $175.00/hr- $1400, Total cost to replace the cooling fan and wiring harness- $3830.19 plus tax. Overheating of the wiring harness poses a significant risk of a short circuit and potential engine fire. The problem was identified by the Kia dealer. No warning lamps, blown fuses, or messages warning of the problem. we smelled smoke on a couple of occasions. Unable to afford the repairs, we traded the vehicle in at a Honda dealer.

ACCORDING TO KIA WHICH THEY POSTED AT THEIR WEBSITE, ELECTRICAL CIRCUIT WITHIN HECU MAY EXPERIENCE EXCESSIVE CURRENT, THEREBY INCREASING THE RISK OF AN ENGINE COMPARTMENT FIRE.TOOK THE CAR TO DEALER, HAD NO PARTS, AS OF 4/12/21 NO KIA DEALER HAS THIS PART. CALLED KIA, THEY SUPPOSEDLY GOING TO SHIP PARTS END OF APRIL. THEY HAVE NO CONCERN ABOUT PUBLIC SAFETY, DESPITE I TOLD THEM I CAN RENT A CAR BUT YOU HAVE TO PAY FOR IT, THAT DECLINED. QUESTION IS, WHY THEY HAVEN'T INFORMED PUBLIC AND SEND THE HECU PARTS TO THEIR DEALERS SOONER? TAKING RISK TO DRIVE A CAR WHICH HAS POTENTIAL TO CUT FIRE SEEMS NOT SAFE AND DISPLAYS KIA NEGLIGENCE.

MY 2018 KIA SPORT AGE AT ABOUT 26,000 MILES WOULD NOT START. THIS PROBLEM STARTED IN SEPTEMBER OF 2019. I THOUGHT IT MIGHT BE THE BATTERY. HOWEVER, KIA DEALERSHIP TESTING IT SHOWS THE BATTERY IS PERFECT. NOW I'M AT 34,000 MILES AND MY CAR HASS TO BE JUMPED TO START IT ABOUT SIX TIMES A WEEK. I HAVE HAD MY BATTERY TESTED SEVERAL TIMES. I KEEP BEING TOLD THE BATTERY'S FINE. AT FIRST IT WOULD JUST GO CLICK CLICK CLICK BUT WOULDN'T START. NOW IT'S COMPLETELY DEAD NO NOISE CLICKING WHEN I TRY TO START IT. THE CHECK ENGINE LIGHT COMES ON AND THEN GOES OFF. THIS IS FRUSTRATING THAT I BOUGHT FOR THE FIRST TIME IN MY LIFE A BRAND NEW CAR DROVE IT OFF THE LOT WITH 11 MILES AND I HAVE THE MOST UNRELIABLE VEHICLE I'VE EVER HAD IN MY LIFETIME. WHENEVER I GO SOMEWHERE I HAVE TO MAKE SURE I HAVE AN ELECTRICAL OUTLET SO THAT I CAN PLUG MY JUMPER BOX INTO JUST IN CASE. I HAVE MISSED APPOINTMENTS BECAUSE OF THIS, I HAVE MISSED WORK BECAUSE OF THIS. I'M READY TO LEAVE IT AT THE DEALERSHIP AND LET THE FINANCE COMPANY HAVE IT. CLEARLY THERE IS SOMETHING WRONG WITH THIS CAR AND NOBODY CAN SEEM TO FIGURE IT OUT. SOMETHING IS DRAWING POWER OR THE ALTERNATOR IS NOT WORKING LIKE IT'S SUPPOSED TO AND POSSIBLE FRAYED WIRE OR SOMETHING THERE. THE CAR IS COMPLETELY STOCK AND THERE HAVE BEEN NO CHANGES MADE TO THIS VEHICLE SINCE IT WAS PURCHASED. AND I HAVE MAINTAINED ALL THE ROUTINE MAINTENANCE THAT SHOULD BE DONE ON A CAR. SOMEONE NEEDS TO HELP ME FIGURE OUT WHY I HAVE A BRAND NEW VEHICLE THAT WON'T START AND THAT IS UNRELIABLE.
