There seems to be a lot of people who own 2012 and 2013 Mazda 3 Sedans (with SKYACTIV-G 2.0L and Halogen Type Headlights) that are dealing with the same issue I am dealing with myself. I have just purchased a used 2013 Mazda 3 with Skyactive Technology and I noticed that when I was braking the headlights would pulse on and off and would continue while I braked. I have been told there is a TSB on this issue (attached) and Mazda is well aware of this happening. This concern is caused by inadequate alternator output controlled by the PCM when the battery is under a heavy load. They are to the point now of charging people for a doing the TSB on the car that is causing the problem of the alternator not producing the proper wattage to support both the headlights and the brake lights at the same time. There are numerous online forum entries that speak of this issue with 2012 and 2013 Mazda 3's. I am very concerned that my headlights may stop working which could result in my death or the death of my occupants of my vehicle not to mention the other motorists on the road around me if my head lights were to eventually fail at night due to lack of proper wattage to the headlights. There are videos on you tube that show these pulsing headlights on Mazda's. I believe that headlights are important enough safety issue that their failing could result in death if the headlights completely failed due to the known fault in these vehicles over time.

ABS Module suddenly start failing causing brake sinks down. Almost crashed because of it. It appears to be a very common issue but Mazda still does not recall these ABS modules made by Ford/ATE. Also, it does not show any ABS warning light, which might be why not many people have called on this as they probably thought it was normal. There is all sort of communication error codes if you read with a OBDII scanner. In fact, Ford had a recall for these ABS modules, citing "stuck or slow-responding valves due to reaction with brake fluid".

The TCM - Transmission Control Module defected - gear lights disappear, down shifting problems, driving, stop in the middle of highway or road while driving, kick / jerk when ATF lights comes on goes off then check engine lights comes on all fluids has been changed drove good for a few days started again took to advance auto parts and auto zone codes stated electrical TCM computer issues, delayed shifting, check engine and ATF lights comes on, DTC codes U1000, LOST COMMUNICATION WITH TCM. The TCM overheats because it is sitting directly on the transmission, under the battery box. My child safety was put at risk daily. This car fails to stop at a traffic light, a slow response when approaching a stop sign or traffic light is dangerous and scary. Mazda's are not safe to drive with a bad TCM, When a driver cannot anticipate the acceleration or deceleration of this vehicle or any Mazda with a TCM the situation is very dangerous. I visited Flow Mazda 04/21/2022 Fayetteville North Carolina invoice number Q10296 took the part for viewing. THE dealership informed us that no one has this part and do not know if the will ever have another shipment. we contacted salvage yards received the same answer. I have sent 8 emails stating problems to the manufacture (Mitsubishi electric company) no response thus far. This is my daughter first year in college she saved her summer money 6600.00$ and purchased this car in March 16, 2022 from Knox auto sales 107 NC-55E, Dunn NC 28334. First day we had all fluids changed. The third day she went to visit her dad 20 minute drive ATF light came on went to auto zone code warning electrical communication, purchased new battery drove car for 5 days good took car to college in Charlotte came home birthday Friday check engine light and TCM code went to church Easter Sunday almost didn't make it home. According to the you tube channels and social media this is a known failure for Mazda automobiles Why are the cars being sold?

I have had my car since 2013 and had no problems with it until I got a new battery for my car. As soon as I got a battery my car would die every other day. I took it to many mechanics and back to the Mazda dealer to see if they could fix it. The mechanics didn't know what was wrong with it and when I took it to Mazda they said it was because my car door light was on, even though it never was. They claimed they fixed it and two days later my car was dead again. Every mechanic and the Mazda dealer said nothing was wrong with the car and they didn't know what was happening. The vehicle sits now because I can't keep calling my insurance company every other day to come out and jump start my car for me.

While coasting, application of the brakes will make the headlights flicker. An ECU voltage monitor registers a drop in the voltage that lasts for as long as the headlights flicker which is approximately 3 seconds. Mazda is aware of this problem and apparently a software update to the ECU will solve it. They offered this for free under the 6yr/60K mile warranty but apparently did not tell their customers.

My headlights dim and flicker, most noticeably when applying the brakes. It was barely noticable at first. My son-in-law, who is an auto and diesel mechanic, brought it to my attention in December 2017 when he was driving it. It is getting worse and becoming more and more of a problem, making it hard to see, especially when approaching a stop at an intersection. I am not sure if the tail lights are also effected, but complaint id 11164134 reported that their's were. My experience with electrical problems causes me to worry that there is a possibility that the headlights will fail entirely, leaving me unable to see while driving at night. This is not a single incident; it always occurs everytime I drive at night, so I am putting today's date in the "when did this happen" field because I can't indicate that it is an ongoing problem. The four complaints about this same problem all indicate no injuries or fatalities; I hope there don't have to be injuries or fatalities for this to be considered serious enough to warrant a recall. Also, the speed doesn't matter, I had to put in a number so I indicated 45 mph, but it happens on the freeway at 80 mph as well as on city streets. There are currently 49,259 miles on the car. When I bought it it had 33,370 miles on it. Like I said, it is getting worse. It is more distracting due to more pronounced flickering and dimming of the illumination of the road.

While driving the power steering malfunctions the radio display keep restarting and the power steering goes out, and then the vehicle powers completely down while driving. I have looked in forums and this issue has been occurring at least since 2004, and has not been fixed! https://www.foxnews.com/us/Mazda-to-recall-Mazda3-and-mazda5-to-address-loss-of-power-steering there is an old article that Mazda 3's have been recalled for this exact issue, but the issue apparently has actually never been fixed. See the attached document, do I need get an attorney to get this fixed since my car is 2013 and the issues are only being addressed in later models? clearly they didn't fix the issue if newer models end up with the same issue. This needs to be recalled is extremely dangerous! I am very disappointed with this and it will keep from buying Mazda ever again due the extreem neglect on this issue by Mazda, it shows a huge lack of integrity.

Headlights and brake lights flicker when brakes are applied. My wife was stopped by a police man to inform her of these conditions.

In the past 6 months, my car battery has died 3 on separate occasions. Whether it's a cold start or I've driven somewhere and turned the car off. No restart, battery dead. Each time I've had to call a service for a jump and have taken it to a local auto parts store where tests have been performed on the battery, alternator and starter... nothing found wrong each time. The last time the car wouldn't start, I have push button start. Even though the battery was dead, the push button was stuck in the 'car running' position, making it impossible to be jump started. The car dealership had no clue why this happened or if it would happen again.

Car's electrical system will cut out without warning. This has happened on the interstate. The radio shuts down, the ability to accelerate is lost, and power steering goes. Several sensor lights come on. I have to fight to get the car to the side of the road and then turn the car off. When restarted the check engine light stays on but the car works fine. This will also happen when the car is idling with the same loss of power. I turn the car off and then back on and it works okay again. This happened in a very mountainous pass recently and there were no shoulders to pull over on and I had no power steering or acceleration. I've taken to several mechanics and they cannot find the issue.

The contact owns a 2013 Mazda 3. while driving at any speed at night, the headlights flickered and flashed when the brake pedal was applied. There were no warning indicators illuminated. The vehicle was taken to maxon Hyundai Mazda (2329 us 22, union, NJ 07083). The contact was informed that the failure was a known issue, but there was no recall and the warranty expired. The vehicle was also taken to crystal Mazda (220 rte 22 West, greenbrookee, NJ 08812) where it was also stated that there was no recall. The manufacturer was made aware of the failure and referred the contact to the dealer. The failure mileage was approximately 96,000.

PCM does not regulate alternator output correctly causing the headlights to flash/strobe and horn tone to fluctuate while braking in motion. The headlights flashing could lead other drivers to believe you are signaling them, and lack of power to horn reduces the audibility and may not be heard by other drivers. Dealership/Mazda is aware of the issue and has provided a "software update" to fix the issue, but has not issued a recall, thus requiring consumers to pay $60-$100 usd for the update if out of warranty. On November 22th 2017 I was approaching an intersection and was braking coming to the red light when a vehicle on a side street waved at me and pulled out in front of me I used my horn of which fluctuated with power, I was able to avoid the crash but it was a close call. I suspect the other vehicle thought my flashing headlights were signaling them to "go ahead". I believe this needs to be a recall as this issue has the potential to cause serious injury or loss of life.

When driving the affected vehicles in heavy rain or in deep puddles, the alternator belt may slip, causing the power control module (PCM) to incorrectly assume failure of the charging system. Once the PCM assumes that the charging system has failed, the vehicle will stop charging and could result in poor acceleration, loss of steering assist and windshield wiper operation, and a possible engine stall, increasing the risk of a crash."

I have a 2013 Mazda 3I 5-door hatchback with approximately 61,000 miles, 90% highway driving to and from work. After having the battery replaced (original) earlier this year, I then noticed that my headlights would flash intermittently, at that time. As the year progressed, the headlight flashing, which presents itself only upon braking or deceleration, became markedly increased and brighter, including the dashboard information systems window inside. I went to an authorized mechanic, who first put my car on diagnostic, which showed that the alternator was very weak/worn. Since I had extended warranty, through a private company, but only until 60,000/5 years, I rushed to make time for the mechanic to receive authorization and replace the alternator, which he did, and my car runs great. There remains, though, the problem with the headlights flashing. Since the mechanic did reset the computer, we were stumped. Then my husband found a service bulletin from Mazda dealing with this specific issue, stating that the car must go to the dealer because only the dealer can reset all the parts of the computer. I then contacted Mazda, but have yet to receive a response. I do not feel that I should be made to pay for this adjustment/repair since Mazda apparently is well aware of this problem with this model car. Just google it, there are alot of M3 owners out there with similar problems, most got resolved because they were still under warranty. Great for them, but that doesn't help me. Not only is this a problem for me since I drive nearly 40 miles each way to/from work each night, but I am tired of other drivers flashing their lights at me, honking, or yelling. It is most annoying, not to mention a safety hazard, since I am a night-time/early morning driver, predominantly driving in the dark. Please advise.

When braking, the headlights pulse. When braking, the car rides bumpy. The stability control light will come on at random times. These have been happening for the past couple years, and all mechanics have said that everything looks fine on the vehicle.

When the brakes are applied and the headlights are on, the headlights will pulse. The flashing headlights are very noticeable when following behind another car. This problem has been happening for weeks.

When decelerating with headlights on while in motion, headlights flicker until pressure is released from brake pedal. Brought to dealership and was charged $26.38 for PCM reprogramming.

Whenever I'm driving and using my headlights and then I step on my brakes my headlights flicker as if I were flashing somebody and I have had my battery tested and alternator and changed my headlights but the problem still occurs I have also looked on youtube to see if anyone else was having problems like this and they were the only thing I haven't tried was contacting the dealer about it. The lights are normal when the vehicle is stationary and I step on the brakes.

When braking or decelerating, the headlights pulse. It looks like we're signaling other drivers at night (although who knows what we're supposedly saying) and it is a serious hazard. This was particularly a problem heading down a mountain at night during a winter storm to have our visibility go in and out. There is already a notice out according to our mechanic, but we received nothing from Mazda and are being charged to reprogram the computer that is supposedly causing the problem.
