When driving at night with exterior lights on, when brake and or gas pedal is pressed the exterior lights strobe/flashes. The Mazda dealership has been contacted about this issue and there is a technician service bulletin stating that the ECM needs to be reflashed/programmed. No recall has been set for this issue and the Mazda dealership stated that I would have to pay $265 out of pocket to have the problem fixed. I believe that because it's a problem with there programming or software that the company should have to issue a safety recall and fix the factory defect. I'm currently in the process of filing a lawsuit against Mazda because of this and I have already filed a complaint with the better business bureau for this issue.

Using my headlamps at night when I break my headlamps begin to flash, as to dim and brighten I took it into the dealership because it was a recall that my Vin number was not part of. They refused to take care of it without a fee. I reported it to Mazda of North America but because the cars older it falls outside of what they would normally do to take care of it. In short, The braking system causes the headlamps to brighten and dim down. I use country Roads, this could become a hazard. Im concerned it could completely go out at some point and leave me in the dark and create an accident

There has always been a massive voltage drop when slowing down or lowering speed. Happens consistently in all driving conditions, highway/city, nighttime/daytime. This leads to all interior lights and more importantly, headlights dimming and flashing whenever the engine speed drops. This often means at nighttime when going around corners visibility is nearly zero until the lights come back on after a few seconds. Electrical systems are all fine with inspection. Upon googling it, appears to be a common problem and software related.

While driving I had noticed that every time I came to a stop light or a stop sign or to even slow down by releasing my foot of the accelerator, my headlights would start to flash. I started to din into the problem by doing research online to see if it was a common problem with my vehicles make and model. Upon reading more and more information I found on the issue I was having with my car. It all seemed to be linked to an alternator issue that Mazda knew about released a recall on it then took the recall away. My car is having the issue for the recall they took away. It poses a danger and a risk while driving. It causes a distraction to the on coming traffic as well as distracts the driver in front of you. I have had cars break hard in front of me thinking I was signaling them for whatever reason. One early morning I had been driving to work on the freeway and my whole car seemed to have shut off and as soon as it went off it came back on.

High beam lights blink/flash when breaking low beam lights dim when breaking instrument lights dim slightly when breaking with both conditions mentioned. Also I had the alteernator checked and it is working like it should. I found other people have had same problem with same year make and model. I am 2nd owner the person who bought it new didnt drive it much and didnt drive it at night so they never knew it had issues. The people with the issues was able to get it fixed free since they bought it new and had the issue happen to them. Seams there would of been a recall out to have this fixed and most dealers know what the problem is. But not the one I took my car to since it is a newer dealer.

Mazda has identified the problem, issued a tsb reference sb-01-019-13. This should be a recall since it's distracting and dangerous to the driver and other motorists on the road.

Headlights flicker/pulsate when applying brakes. This is a well known issue with 2012-13 Mazda3 that requires a software update to remedy. Currently, Mazda is charging a minimum of $99 to 'diagnose' the issue. Since the issue occurs in motion, I do not have photos, but I do have videos. Given that this is a safety issue caused by faulty software that only Mazda can update, there is no reason that owners should have to pay them to fix their own mistake. It's a scam, at best.
