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.

On 09/23/2017 I was driving on the highway on a sunny day, around 80 degrees with my sunroof closed, and the sunroof cover open to allow the sunlight in. While driving on the highway about a mile from my exit, I heard a loud bang that startled me (sounded like gunshot), all of a sudden I felt stuff hitting my head, face, and shoulders. I look up and saw my sunroof exploded with shattered glass flying all over my car and realized glass is what was hitting me face and body. Luckily, the sound of the sunroof exploding and glass flying all over the place, I was able to still keep control of my car. I slowed down to exit the highway and pull into a parking so I could get out of the vehicle and look it over. I never saw anything fly up at my car, or at my car when this happened. There were no vehicles close to me when this happened. As I looked over the car, I saw how badly the the sunroof looked and glass all over my car seats. I picked pieces of shattered glass from my hair, shirt and pants. I immediately called my insurance company to file a claim, and took pictures of the sunroof. The car was towed to a storage lot until the body shop was open on Monday. I requested for a local Hyundai dealership to look at it first before the auto-body shop because my car is still under warranty. A gentleman from dealership's service department took pictures of sunroof and submitted to Hyundai on 09/26 to investigate the claim. On 09/28, that service advisor from the dealership left me a voicemail that the claim was denied. I called and spoke to that service advisor to obtain a reason for the claim being denied. He said Hyundai's investigation revealed an outside influence cause the glass to break, but I was provided with no report or any other explanation on how they came to this conclusion. I saw some 2012 Velosters were recalled for sunroofs exploding. It's a huge liability.
