Headlights pulse, like others have stated when decelerating, as in coming down a hill while gently braking. I am putting the latest date of occurrence, but its been going on since about summer of 2015. Would like this resolved.

When the car decelerators, or more noticeably, when I'm breaking, the headlights flicker, almost pulsing. It has not gotten me into any trouble yet, I've heard of near hits because other drivers thought they were allowing them to merge in front of them. I'm most afraid that someone will think I'm threatening them by flashing my lights at them. As if I'm angry they cut me off and flashing my lights in anger, for example. It's very rare for this not to happen when it is dark. My boyfriend is also afraid that the lights are going to go out spontaneously, leaving me in the dark.

When decelerating (braking) headlights flicker. This makes night time driving dangerous & difficult.

- Sullivan, ME, USA

While driving the car engine suddenly turns off. Radio and headlights remain on, but power steering stops functioning. This has happened 5 times, 4 times on surface streets and once merging onto the highway. Local Mazda dealership could not find anything wrong the two times I have taken it in. There is no code being displayed.

Horn gradually failed, became weaker and weaker, eventually totally silent. Looked on google to find location (it is very tight in there!) discovered numerous complaints of failed horns for this exact make and model. Horn is made by fiamm (italy). Examined horn, the adjustment screw is sealed. Failure is internal. Vehicle is two years old, has 39,000 miles. Replaced horn with $10 aftermarket item, all ok now. Took me about 45 minutes to do, and I am an experienced mechanic (cause is absolutely miserable access, only had to remove one nut and one wire, the trick is getting to it), I fix everything from wristwatches to airplane engines. No accidents, no injuries, but you must have a working horn... this is my wife's car, and I want her to be safe.

Noticed flickering of headlights during night driving while braking. This headlight flicker was repeatable while night driving and braking at moderate to highway speeds.

A few weeks ago, the low battery indicator came on indicating that I needed to replace my key fob battery. My car has a keyless ignition/ push-button start. I replaced the battery in each of my key fobs about a week later. After an additional week, my car will not start with either key fob. The dashboard states that the key is not found, even though I replaced both key fob batteries. I had to take the ignition cover off and insert the key to start the car. Mazda is charging me $100 just to get this looked at.

The headlights flicker or pulsate when I brake or decelerated my 2013 Mazda 3 hatchback with the 2.0 L engine. Night driving is dangerous.

When I started driving and put on my headlights. Everytime I put on the brakes the headlights dim as the brake light is pushed.

Driving 60mph on major freeway during rush hour, light rain. Check engine light came on and stayed on. A few minutes later, every warning light came on and I lost the power steering. I pulled to the side of the highway and turned the car of, waited 10 minutes and started the car. Check engine light remained on and all other warning lights were off. Started driving and 10 minutes later all the warning lights came on again and lost power steering again. Left vehicle in garage over night with hood up thinking it was due to rain/moisture/computer problem. Car started fine in morning, no warning lights. Took it to dealership and they said it was a lose battery cable. I am thinking it was more than that. I have noted my concern and will await the next heavy rain.

I drove the car on Friday, 4/26/13, for about 120 miles. On 4/29/13, I found the battery died. This was the second time for this brand new car about a month. It's not a reliable product. The service lady in maita Mazda sacramento told me that I should drive the car everyday to keep the battery working. Why didn't they told me before I brought it.
