My vehicle died while I was driving at a low speed into a parking lot. I found out the issue is the positive terminal of the car battery is loose, so the battery cuts in and out. Also, since the positive terminal is loose, the battery acid spills out and corrodes the cable. I have since replaced my battery with a new Mazda car battery, and my mechanic tightened the positive terminal by inserting a metal coin (since the battery harness part has been discontinued). However, I noticed today that there is corrosion on the positive battery cable, so some battery acid is leaking out of my new battery. Also, I noticed that when I start the car, most times the car will die on the first start and need to be restarted in order to stay on. I don't feel safe driving my vehicle B/C I am afraid it will die again while I'm driving it.

Headlights just stop working. I have to hit a bump in the road to turn it back on. Very disappointing.

The car was parked for around 5 hours last driven around 10:30pm awoken to screams of a fire in condo complex car was in flames fully engulfed destroyed two condo's and 4-5 cars.. my Mazda6 was the source per two different insurance investigators. One investigator stated that the car's wiring may have been the cause.. as the batter was destroyed and all electrical lines were severely burned. Another investigator positively confirmed the fire started towards the left rear of the car. The car had just came back from a day trip and was used most of the day prior to the fire. My investigation into Mazda 6's and fires turned up a surprising amount... searching *salvage Mazda6* in my year range turned up a large amount of vehicle fires... with the same burn characteristics. When I awoke to my car on fire the car horn was stuck on, and the headlights were mysteriously on also... I have photos of this and the stages of the fire and the aftermath.. it even made local news... I do believe there are problems with these cars... this car was dealer serviced and was always given an inspection... yes this was a year ago, but I do believe there was a malfunction with the car. I have plenty of photos of the car ect available. Attached is just one of the many news coverage of the scene. Car was a clean title dealer maintained vehicle showing no signs of malfunctions. www.kcra.com/news/local-news/news-sacramento/car-fire-spreads-to-apartment/-/12969376/15228862/-/117ugyc/-/index.html.

I purchased a new Mazda 6 in 2005. Since then I have had to replace the battery 3 times. Each time the battery went out with no warning. It would be driving fine, I would park and get out. When returning to the car, it will not turn at all. Internal and external lights and radio worked fine but car will not turn. The first two times the battery was jumped and the car was taken to a Mazda dealership and replaced under the Mazda battery manufacturer warranty because they went out before the 36 month warranty. The last time in August of 2010, the battery will not jump. I paid to have the car towed to a Mazda dealership. I was told that the battery had a crack in it and acid leaked out and as a result, the engine wiring harness needed to be replaced. At this time, the battery was covered under the Mazda manufacturer warranty and the wiring harness was covered under my Mazda extended warranty plan. I did some research and found that there is a possibility that the leaking acid could have caused an explosion and my family was lucky. I received a call from the dealership saying that the manufacturer warranty will replace only the battery itself and the extended warranty is denying the entire claim because the damage to the wiring harness was from the battery acid. So, here I am with a battery under Mazda manufacturer warranty, covered by a Mazda extended warranty plan and I had to pay for everything except for the battery itself. I paid for the tow, the labor and parts for the harness, rental car while it was being services. And the fact is that there was a faulty battery that leaked acid, put my family in danger, and I was stuck with the collateral damages. Considering that this was my 3rd battery replacement in 5 years, I'm certain there is something wrong with these batteries or something in the car itself. I am now driving with my 3rd Mazda battery replacement and afraid of when my next incident is going to be..

I was reading this complaint section and noticed that there was someone complaining about the same issues I was having. I own a 2005 Mazda6 sedan sport -- it has died three times on me, for no apparent reason. Once at a stop sign, again at a metering light on the freeway and then again in the middle of a busy intersection in san francisco. I have documented all three incidents and have brought to the dealership, but they never really found anything "wrong" -- but obviously something is wrong if my brand new car dies. This was back in November and it's been fine ever since (it's April now), but I still have some sort of anxiety when driving - not knowing if I will reach my destination or not.

I own a 2005 Mazda 6 I sedan. After owning my car for 7 months it has turned off 3 times while driving. Once I was on the highway the other two times I was at a stop. I have taken it to the dealership twice to have the problem examined and no problem has been found. My car has received all of the scheduled maintenance. Yet the problem still occurs. When the car stalls it usually starts again immediately however I don't think a new car should have this problem.
