2014 Hyundai Veloster

My ac unit switch melted due to the wires getting too hot and causing the unit to no longer work. I believe this is a safety issue due to possible fire with the wires getting burned. After doing some research this is a common issue in my car and I believe hyundai should be required to replace my unit before it causes more damage inside the unit.

The contact owns a 2014 Hyundai Veloster. The contact stated that while driving at an undisclosed speed, the vehicle was shaking and hesitated to accelerate. The check engine warning light was illuminated. The vehicle was taken to the dealer where it was diagnosed that the wiring harness connector needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 106,000.

I purchased my 2014 Hyundai Veloster as a CPO back in January of 2018 with approximately 37k miles. Currently it has 95,637 miles. Within the first couple months of ownership, I noticed that the vehicle was sporadically acting up during acceleration (specifically when shifting between 2nd and 3rd gear). During this process it acts as if all of its power is shut off momentarily and then comes back on, which can potentially be dangerous when accelerating into high traffic areas, or busy intersections because not only does it lose acceleration power but steering as well. I brought it to the dealership right away, but because it never throws any trouble codes, nor does it happen on command - they cannot pin point the issue. Initially they changed the alternator. The second time, I believe, they changed the knock sensor or the Camshaft position sensor. In short, I’ve brought it to the dealership several times and have filed numerous complaints to Hyundai Consumer Affairs, but to no avail. Most recently (March 2022), it happened when both of my stepchildren were in the car while we were returning from the beach. I accelerated from a traffic light and was going around a bend when it happened causing me to slam into the curb and caused nearly $1700 in damage, which I had to pay for out of pocket because at this point it is out of Warranty- even though it’s been an ongoing issue pre-warranty lapse. Then to top it all off, I was leaving work this evening to go to an appointment and all of a sudden it began smoking from underneath the steering column. I quickly pulled into the turning lane and popped the fuse box lid open. Instantly I noticed that a wire harness was on fire, which luckily I was able to blow out after several attempts. I’m at my wit’s end with this car, with the dealership, and with Hyundai….. I need help and don’t know what to do!

THE AC/HEATER BLOWER MOTOR CONTROLLER IN THIS VEHICLE AND EVERY MODEL THAT SHARES THE SAME STYLE KNOB HAS A SERIOUS DEFECT. ALONG WITH THE FIRE HAZARD THIS PRESENTS IT ALSO EFFECTS THE USE OF DEFROST WHICH CAN BE A SERIOUS ISSUE IN SOME CLIMATES AND THE SWITCH MAY FAIL COMPLETELY RENDERING THE DEFROST FUNCTIONALLY UNUSABLE. ATTACHED YOU WILL SEE IMAGES OF THE INSIDE AND OUTSIDE OF THE SWITCH IN QUESTION AS WELL AS THE CONNECTOR FOR THE SWITCH WHICH HAVE SUFFERED SERIOUS HEAT DAMAGE. THIS IS A FIRE HAZARD. HYUNDAI CHOSE TO USE THE SWITCH ITSELF AS THE CURRENT PASSING CONDUCTOR INSTEAD OF A RELAY AS USED BY MOST MANUFACTURERS. THIS DECISION IS CLEARLY REFLECTED AS A NEGLIGENT ONE WITH REGARDS TO THE STRUCTURE OF THE SWITCH AND INCORRECT GAUGE OF THE WIRING USED FOR SAID SWITCH. WITH NORMAL USE IN ANY POSITION ON THE DIAL, THIS ISSUE WILL CAUSE THE WIRING OF THE CONNECTOR, AND THE INSIDES OF THE SWITCH TO OVERHEAT. THIS IS NOT A MATTER OF FUNCTIONALITY, THIS IS A MATTER OF SAFETY. WITH THESE LOW GAUGE WIRES BEING USED FOR THIS IT POSES A SERIOUS RISK OF FIRE. PLEASE SEE THE ATTACHED PHOTOS FOR EVIDENCE OF THE SWITCH AND CONNECTOR DEFORMATION CAUSED BY OVERHEATING. PLEASE BARE IN MIND THAT THE SWITCH COMPONENTS AND CONNECTOR APPEAR TO BE MADE OF PA6, A GLASS FIBER REINFORCED NYLON WHICH IS INTENDED TO STAND UP TO A GREAT DEAL OF HEAT. ADDITIONALLY THE WIRE WRAP (PICTURED BELOW) MEANT TO PROTECT THE WIRING ON THIS CONNECTOR FROM RATTLING IS MADE OF A CLOTH/COMPOSITE MATERIAL, WITH THE ABILITY TO MELT AND CATCH FIRE. THIS ISSUE IS A CONSTANT BEING DOWN TO THE WIRING. IN MOTION, STATIONARY, OR OTHERWISE HAS NO BEARING SO LONG AS THE CLIMATE CONTROLS ARE BEING USED. THANK YOU FOR YOUR TIME.
