Selected complaints filed with NHTSA by 2010 Mazda Mazda3 owners, lightly cleaned up (personal details are redacted by NHTSA).
A substantial amount of water has made its way into the headlight housing. This has caused the driver side light to go out. There is no evidence of any damage, cracks, or failure otherwise. It seems, like thousands of other Mazda3 drivers, the seals have failed. My particular model has the auto leveling and turning headlights. Cost to repair will be well over $1,000. This is a well known problem to Mazda. Lack of lighting is a safety issue. High price of repair is a serious bar to fixing the issue and returning to safe driving. I was unaware of the failure as no warning is communicated to the driver.
My 2010 Mazda has had a build up of condensation in the driver's headlight for some time and recently the driver's headlight went out. I was advised by the dealership that I would need to replace the entire headlamp which requires removal of the bumper. I would be looking at close to $1000+ to complete the repair. I declined the repair as I wanted to do more research on the safety bulletins that are posted for this same exact issue. The dealership declined to repair the issue based on the published safety bulletins. Recently, condensation has started in my passenger side headlamp and that headlight is now out as well. It should be noted I live in the dry southern california environment so my car is hardly ever exposed to water for condensation to even be building up. …
There are (3) existing NHTSA reports on this that I am aware of: 10037949. 10037655 & 10052155. Purchased a 2010 Mazda 3 off a dealers lot 1.5 weeks ago. The following day while driving the left head light was out. There was condensate in the lens. The car has HID lights. To access the bulb the car bumper etc. Had to be removed. Local shop replaced both bulbs and ballast. Cost $1,200 +. Three days later the same bulb went out. Shop is now replacing the lens and ballast (again). $1,898. After checking on the internet we found that it a common problem for this car's headlight lens to leak. Some people reported multiple failures with the same problem. Mazda has 3 service bulletins on this problem for this year car. 09-003-13, 09-005-11, & 09-057-10.
One of the two electricals broke loose that's connected to the battery that starts the car. My car literally stalled out on me in the middle of an intersection. I was almost hit because of that. Another issue is my right back tire. One of the lug nuts won't come off and that is a safety issue. If something happens to my tire, I'm not going to be able to get a new tire to replace the old one. Another issue is the light on the ceiling of my car broke. The wires are exposed. My dashboard in my car is also melting.
The car will intermittently not shift out of park due to the shift lock not releasing properly, and the stop lights and horn are not functioning properly as well. This seams to be typical of the Mazda3's due to the horn shorting the fuse and the brake switch going bad, and definitely makes the car more accident prone. Others seam to report the cruise control functions stop working due to the same fuse being used for stop lights and the cruise control function.
Takata recall , dashboard starting to meltdown really bad. I seen alot of people got same problem.the vehicle is my commuter over time it starts to get sticky fibers get stuck on it needs to recalled asap for the timing of the air bag deployment it's really unsafe please help . The headlights assembly contains alot of moister after a car wash. Moisture can cause an electrical problem and burn the computer itself
My driver sideheadlight is out again. I went to the dealer last month with no headlight and condensation inside the headlight housing. Paid $750 for them to replace the unit. Its barely a month later and the same light is out again after it rained two days before. Its again full of condensation. The headlight housing is faulty as it allows water to come inside and short out HID bulbs and unit.
2010 mazda3s grand touring, condensation accumulated in head lamp resulting in head lamp bulb failure. The cost to replace head lamp assembly is $2500.00 $250.00 just for the bulb. Thousands of noted on line complaints with photos with no damage to assembly but the sealant has failed. Mazda dealership parts department acknowledged this is a known issue with the Mazda3.
Started to notice sticky residue on the inside of the windshield. Hard to clean off making for a visibility issue. Days later after the vehicle had been parked noticed the dashboard was very sticky and appears to be melting. After some investigation online realize this is an going issue with these cars and others. I.e. Toyota/Lexus .
The electrical systems is not working right the lights on the in side of the car come on when you get up to 75 to 80 MPH they start flashing.the air bag light light come on the steering column lock up a lot of time were I have a hard time getting the key in the ignition
