My drivers side front headlight issue first began about 50K miles (Oct. 2012). The headlight went out and I went to replace the bulb but it wouldn't turn on. My mechanic fixed the brakes around the same time and took around the block, went over a bump and the bulb came back on. I've had issue ever since. Usually I can give it a little tap and it will come back on. Not this time! ive replaced the bulb twice since 2013, it's at 80,555 miles now and it won't come back on at all! there should be a recall, for I've searched the interent and found many Mazda 6's in many model years that have this same issue. My drivers seat belt just began getting stuck at 80,300 miles. The day before father's day was the first time it happened. (June 20, 2015). I went to target and I couldn't get out of my seatbelt when I turned the car off. I jiggled it and pushed on it repeatedly until I heard it click again and it finally released. This is incredibly unsafe and I have to be very careful how I put my seatbelt on until I hear the "right click" or it won't let me out. My cruise went out on my way back from ok in Aug. 2013, right around 65,000 miles I believe. I was coming up on the ca border and had to stop for inspection and as I slowed down, my car began lunging forward despite the fact that I applied the brakes. I turned it off and back on and it stopped until I used the cruise again. Then it'd lunge again when I'd slow down or attempt to stop. I called my friend and he said to stop using the cruise. The problem has not continued, but I also haven't used the cruise since 2013. My car doesn't even have 100K miles and I bought it new. I've maintained it and it still had other issues. The keyless entry, bose 6 disc, alternator and thermostat have all malfunctioned! the lights on the radio display don't light properly and the headliner falls down despite my best efforts to fix it....updated 01/06/16

I was driving with my 7 year old in my 2005 Mazda 6 when I noticed the car was accelerating on its own just a little bit. I didn't think much of it at the time. About 2 minutes later the rpms went up and down 3 times( 1000 rpms each time). Immediately after that, my brakes stopped working while I was going about 35 mph. I had the brake pedal floored and it barely stopped in time. I managed to stop with my emergency brake and put on my hazard lights for a few minutes while the car was still running. I had to get out of the road so I attempted to reverse very slowly and the brakes were suddenly working. I pulled the car in a parking lot with no brake problems and got it towed to a shop. The shop is telling me they are not finding any problems but I don't feel safe in the car without an answer! im worried it may happen again and cause an accident next time.

I was driving home from work today. I was driving on a road not far from my home and going about 40 mph. My foot was not on the gas but the car began to suddenly accelerate. It suddenly accelerated to over 50 mph. I began to brake, but it felt like I was trying to brake at the same time someone was pressing hard on the gas pedal. I put the car in neutral and pressed the brake as hard as I could. It was a definite hard push on the brake -- as if I had lost power brakes. There were cars ahead of me stopped in the road because of an accident. I managed to stop -- but barely. I almost hit the car in front of me after finally stopping my car when it surged forward several feet while my foot was firmly on the brake. I managed to get my car on the side of the road and put it in park. The engine continued to rev up and down as if I was about to start drag racing even though I did not have my foot on the gas pedal. This continued until I turned the engine off. When I turned the engine back on, the revving had stopped. A similar, but briefer incident happened a few weeks ago. I had to put the car in neutral, brake as hard as I could and use my emergency brake to stop the car. This issue happened the first time about 3 years ago. I almost ran into the plate glass window of a store. When I was able to stop the car and put it in park, the engine revved repeatedly (very, very high that time) and did not stop until I turned off the vehicle. I took the car to the Mazda dealership. They called in engineers and could never replicate the problem and said it was unlikely to ever occur again. Well now it has occurred twice in the past few weeks. This is an incredibly dangerous safety issue. Someone will be hurt or killed. I see that the Mazda tribute has been recalled for a similar issue. People complain on the internet of this issue with the Mazda 6. please help!.

The car unexpectedly accelerated with my foot of the gas pedal. I was driving around a curb at about 20 mph and all of sudden it increased to 40 mphs, and the RPM needle jumped up and down, and finally it got stuck at 3rps. I was on a flat surface and the vehicle continued to accelerate and make loud engine sounds. I tired to brake but the car continued to accelerate, I kept driving until I was able to let other cars pass, and pull over and put it in neutral. In neutral the car still accelerated, and made noises, that I then put it in parked. However in park the RPM was still stuck at 3 and the mph needle bounce between 0-40 mph. Finally after a minute the needle drop to 0 mph, and I turned the car off and restarted it. After waiting 5 minutes I restarted the car and it acted like nothing ever happen. The next day after driving 15 minutes it repeated the same activity. I have contacted my dealership and set up an appointment. Apparently this is a common problem with Mazda between 03-05 with acceleration issues. However the is very dangerous, for me and my children and other drivers on the road. This could cause a accident or even death. This is something Mazda needs to take seriously and needs to recall and repair to correct the problem.

2005 grand touring gets stuck in gear while driving. The vehicle became stuck in gear three time while driving on the freeway. The consumer took her foot off the accelerator yet the vehicle continued to move at 60 mph. The consumer pressed the brake pedal but the vehicle continued at 60 mph. The consumer put the car in manual 6 speed and the vehicle bucked then worked normally. As soon as the vehicle was put back into automatic mode the gears became stuck. The vehicle was taken to the dealer but they were unable to duplicate the problem. The consumer noticed condensation on the inside bottom of the windshield. The check engine light illuminated due to failed throttle body. The radio experienced problems. The left rear wheel was bent and caused vibration while driving.
