The driver's side low beam headlight wiring harness melts and seems to be continuing problem. Even after replacing stock, (which melted,) with a better wiring harness it still began to melt and loose circuit, but like I said it was doing this before ever being replaced. Happens every couple months are so depending on amount of night driving. I have read several complaints about this happening to several owners of the same vehicle on the same drivers side with the same original harness and replacements doing this same melting and frequent on/off short circuit malfunctioning. Possibly causing a fire or fried wiring or loss of headlight causing unsafe conditions

Tl* the contact owns a 2009 mazda 6. The contact stated that the dashboard was melting, shiny, and sticky to the touch. The reflection from the sunshine and approaching headlights from oncoming traffic at night affected the contact's vision to safely operate the vehicle.

Just like all the online discussion boards indicate, my driver's headlight does not turn on regularly. Once I could fix it by hitting on the headlight assembly, but now that does not work any more. Bulb is fine.

Headlight harness comes loose frequently, resulting in loss of headlight. Must either hit the headlight forcefully or manually secure headlight by removing wheel well. Hundreds of people on youtube have reportedly experienced the same defect. Uncertain whether this occurs while stationary or moving, but imagine vibration from motion will knock it loose again. This photo was taken after manually adjusting the right headlight via the harness in order to turn it back on. The right light is dimmer than the left, suggesting a ground issue.

Both headlights at different times have gone out, been replaced and go out again within a few weeks of replacing the bulb. If you bang on or hit the headlight it may come back on. Have replaced the drivers side 4 times in one year. Hitting bumps in the road may bring the bulb on or off also.

The driver's side high beam headlight has gone out. Hitting in makes the light turn on again, but it goes out within a few minutes.

Driver side headlight randomly goes out that is a safety issue at night when driving.

Shortly after I purchased my vehicle (used) I noticed that my headlight on the passengers side was dimmer than the other and while is was driving, the light would go on and off, I figured it just needed to be replaced, but if you bumped the light it would come back on and work for a few days and again would go through the same thing over again, this became to be a safety issue to me because I work at night and with this issue happening intermittently I figure id change the bulb and hope for the best. Bulb changed same issue continued, I researched this on numerous sights to see that other mazda owners where going thru the same problem, edmonds had people on their sight with the same issue, headlights are on the top for safety if you cant see or be seen the worst can happen. Help us mazda6 owners.

The entire passenger side dashboard is gooey, sticky black. If you touch it gets all over your hands, and everything will stick to it. It appears to be melting away. This started a few years ago. Recently I noticed the rear headlights look as if they are warped from the inside, as if it was a melted candle.
