I purchased this vehicle for my 16 yr old daughter 1 yr ago. The car has a clean carfax and has had no accidents. Upon purchasing the car the headlights continue to burn out. Taking it to a Mazda dealership i learned the headlight assembly unit was melting. I had to purchase 2 used headlight assembly because new from the dealership are 1,000 a piece. 2 used but perfectly working headlights were installed and within a yr the headlights had burned out again. I went to change the bulbs only to learn the headlight assembly were once again burnt. I have to purchase 2 new headlight assembly again but the mechanic can not guarantee that this burning situation won't occur. After calling around to places to find headlight assembly I have come to find out many are burnt. This seems like a real problem considering you need headlights to drive at night. Spending 1,000 everytime my headlights burn out seems 100% unreasonable and the fact that there is cleary a wiring issue within the headlight assembly unit itself seems to be a problem. I have been on multiple forums and this is a common issue. Please fix the problem!!!!!!

Tl* the contact owns a 2010 mazda 6. While driving various speeds, the sunglass holder suddenly fell down and obstructed the contact's view when using the rearview mirror. The vehicle was taken to the dealer (brown mazda in fairfax, va) where it was diagnosed that the sunglass holder would need to be replaced. Also, when removing the ignition key from the ignition switch, the metal section of the key would break off. The failure had not been diagnosed. The vehicle was not repaired for either failure. The manufacturer was notified of the failures. The failure mileage was 40,000. *tt

Tl* the contact owns a 2010 mazda 6. While driving 40 MPH, the door ajar warning indicator and the dome light illuminated independently. The contact coasted the vehicle to the side of the road and noticed that all the doors were closed. In addition, while at a stop light, the vehicle stalled and all the warning indicators illuminated.

The vehicle was not taken to a dealer or independent mechanic for diagnostic testing or repairs. The manufacturer was contacted and did not assist. The approximate failure mileage was 120,000.

Low beam intermittently turns off. Sometimes a firm slap on the headlight is a temporary resolution. I initially thought it was the bulb itself, had it replaced but the problem continued. There are lots of youtube videos on this issue. Mazda keeps telling that this is not a safety issue and they refuse to do anything. If they want to do business in the USA, they need to be safe or they need to go back to where they belong. This issue has been happening since 2014 (I bought this car in 2013)

The low beam headlights on my 2010 mazda 6 keeps going out. I've replaced each light at least twice in the past 4 years. While I was driving last night, both headlights went out. I think mazda know that this is a problem in this vehicle but instead of fixing the root of the problem, they keep charging me $60 for each headlight bulb.

The low beam headlights on the car take turns going out for some reason. I have had the car for five years, bought it brand new and have had to replace headlight bulbs at least 8 times. I have read several other review about the same issue. This is a safety issue, if we to be driving at night and both headlights go out that would be very dangerous. Second issue: every winter when it gets colder the cars electronic system seems to run much slower and the blue tooth, cd player, etc. Will not connect and there has bee three instances where the car will make a loud popping noise while it is in motion and the whole stereo system, blue tooth, dashboard lights will power off and I'll have to reset up the blue tooth.

Vehicle was repaired as part of the federal safety agency campaign number: 11v134000 on 21 july 2011. However, vehicle's fuel tank cracked in april 2013 and had to be replaced at owner's expense. After smelling gasoline after fill up and noticing a puddle of gasoline in driveway in april 2013, owner had vehicle towed to mazda dealer for repair. Dealer replaced tank on 15 april 2013. Over the last year and several attempts, mazda has since declined to reimburse owner for repair and reprogram ecu per the federal safety agency campaign number: 14v114000. Recall from july 2011 was supposed to eliminate the possibly of a cracked fuel tank, but it didn't. Owner has pictures of cracked tank and dealer work orders from july 2011 and april 2013 and can provide if needed. Owner worried that if the ecu isn't reprogrammed, the tank will crack again.
