  • 93,000 miles


The car's cmu needs to be replaced so the car has no functioning radio, gps or bluetooth. The screen on the dash constantly tries to reboot, which is a distraction and hazard while driving, particularly at night. Mazda has not been able to give me any timeline for the repair and claims it is not covered under an extended warrantee that it issued for the touch screen in this model and year Mazda3.

Unfortunately a picture will not work for what us happening in my vehicle. The navigation hub in my vehicle with start to phantom press buttons when stopped or driving. When stopped it will start to open menus and change settings as well as open the phone and attempt to dial numbers on it own. This can be very distracting while stopped as it is constantly beeping and clicking which prevents me from paying attention. While the car is in motion it is unable to dial numbers but will still go into menus and start changing settings which is a huge distraction from the road while driving. There is no way to turn off the system and if you try to mute it with the mute button the system has unlimited itself and continued to rapidly change setting or select different things within the menu all the while making very audible and distracting noises. This is a known issue that has been seen in many forums and Mazda has not done anything to fix this for their customers. My fear is that of the fact that it can take your attention away from driving while this is happening. It is not a consistent condition though and will not do it for days, weeks or months but then will all of a sudden start up again. Resetting the system does nothing to fix this as well as turning the car off then on again. I hope that this issue may be recalled as it poses safety hazards for anyone with this problem to be distracted and not pay attention to what is happening on the road which could lead to traffic collisions especially in in climate weather.

Occasionally the engine will hesitate when accelerating, and then the check engine light, tpm, and stability control light will illuminate on the dash. Less frequently, the engine will occasionally stall while driving or while sitting at a stop light. The lights on the dashboard will remain illuminated, so I do not think it's a total loss of power.

The contact owns a 2014 Mazda 3. the contact stated that the vehicle had stalled several times with no warning. The dealer heritage Mazda catonsville (6616 baltimore national pike, catonsville, md 21228, 1-(844) 224-1951) recharged the battery as an interim repair due to the intermittent loss of power. However, they had not provided a permanent remedy so the vehicle was not repaired. Within days, the vehicle had continued to have a loss of power and stalled. The manufacturer had no recall campaign and had only 1 tsb on the electrical system for this year, make and model which was unacceptable to the contact. The manufacturer was notified of the failure, indicated that there was no recall campaign to provide a solution so the contact was uncertain if the vehicle may be repaired. The VIN was not available. The approximate failure mileage was not available.

The 2014 Mazda 3 has a notice bulletin regarding a known issue on the radio and connect system failing. Mazda will not replace or fix this issue without telling customers to pay $1010 for a new hardware unit which some have reported not fixing the issue. Mazda needs to recall this part as it affects the entire computer of the car by not allowing the driver to control the radio, maintenance, hands free communication, navigation, and car settings. Shame on Mazda

On numerous occasions when I attempt to accelerate, the vehicle does not move forward and feels like it might be jammed. The car will then propel into gear causing my vehicle to skid out. The problem is intermittent. It appears to be happening the worst when making right hand turns. This has resulted in one accident, and two near fatal accidents.

I was driving on the freeway and decided to pass a diesel truck to get over in to the exiting lane on the right.... I started to pass the diesel and realized that I would need to pass faster to make the exit... I pushed the gas pedal in harder to accelerate and as I was picking up speed my car just locked up.... it felt like the car stalled..... and the car went off.... I had to very quickly pull out of the lane and to the side of the road as the car was no longer operating... I narrowly missed being plowed by the diesel truck... and was able to pull off to the side. I tried to restart my car by pushing the button and it wouldn't restart an all these light were lighting up in the console. I had to wait about 10 mins and finally my car came back on.

All of the warning lights illuminated. The failure recurred four times. The vehicle was taken to a dealer where it was not diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 6,700.

A few times when starting up the vehicle, the Mazda emblem pops up slowly, then fades away, and the lcd system screen will continue to be a blank, black screen with no response until I restart the car. About 7-10 times it has happened where I'm driving and all of a sudden the music will stop, then the lcd screen shows a Mazda emblem, and the system reboots itself. I'm taken notes and have tried to find commonalities when this happens, but have not yet. I've mentioned it each time I get a Mazda oil service, but the techs never find anything. I also have video recording of one of the instances where it lasted particularly long.

My car is equipped with a push to start/stop (keyless) "feature". I pulled my car into the garage last night (with the radio off), pressed the start/stop button to stop the engine, and went inside. When I woke up this morning, the car was still running, all night inside my attached enclosed garage. Co meter measure non-zero ppm levels a few hours after shutting the car off. Other then the radio, there are no obvious non-audible indications that the engine is running / not running. Additional expectation would be the car should be smart enough to automatically shut itself off after idling for extended period of time. Mine was running in the garage for about 6.5 hours.

I have had two continuous issues with my 2014 Mazda 3; the navigation system shuts down and then begin a cycle of continuously shutting down a rebooting and the heads up display at times does not pop up when I start the vehicle.the only way to stop this is to pull over, shut off the car and then start it back up again (this generally fixes both the navigation and hud issue, although these issues do not seem to be related as the have not occurred at the same time before.) this certainly seems like a software issue as rebooting does fix the problem. This happened multiple times and mostly occurs at the end of long trips, when I need it most. In some instances this has led me to take wrong turns in heavy traffic or forced me to pull over in heavy traffic in order to figure out where I am going. Mazda needs to deal with these issues as they can pose a safety hazard to those following the navigation directions. As always do not depend solely on a navigation system, especially the one in the 2014 Mazda3. It will enter into a cycle of continually shutting down and rebooting when you need it most. I have brought my vehicle to a dealer to update the software to the latest version a few months ago, it did not fix the problem. I went to a dealer for a recent oil change I mentioned the problem and they did not even seem to know what the latest software version was or why I would want it updated. I hope that most dealers would update the software for a car under warranty when they complete an oil change, or at the very least know and make the customer aware a newer version of the software is out so an update can be scheduled. I plan to complete this update, but no one at the Mazda service center I went to was able to tell me what the update changed/fixed. I am highly disappointed in the vehicle's navigation and hud. Caveat emptor when buying a year one model.

There is a serious issue with the reception for the radio. It constantly fades in and out and is so bad that I cannot use my radio in a large metropolitan area. I brought the car in to the dealer to recreate the issue and they said that they couldn't hear it.

MAZDA3 4-cyl

  • 1,853 miles
On May 7, 2014, at approximately 11:00 pm I parked in a parking space, on a hill, at towson woods apartment complex. I turned the car off with the emergency brake engaged at over 3/4 of the way up. I was standing about 10 feet outside my car, which was off and stationary, talking to a friend for approximately 10-15 minutes when my car started to roll backwards of its own Accord. I attempted to push it, which failed, and then I jumped into the drivers seat and tried to pull the emergency brake up as far as it could go, which did not stop the car. It then crashed into the bumper of another car. Because the wheel had been turned to the left when I parked, the car had rolled at an angle so that only the right side bumper made contact with the other car?S big aluminum bumper that sticks out. After driving the car out from against the bumper, I found there to be cosmetic damage that included the bumper sticking out. (estimate $855) May 16, 2014 at 9:00 am. After approximately an hour and a half I was told that the technicians found that the emergency brake applied when the handle was applied all the way up, which they termed "within normal operation." However, for ?peace of mind, ? they told me that they tightened the brake so that now it only goes up 5 clicks. The actual wording used is ?tech made minor adjustment so ebrake does not go all the way up.? on May 21, 2014, at approximately 7:05 pm, I started my car and a flashing light on my dashboard appeared. This is the ?bsm off" light, in regards to the blind spot monitoring. I read the manual and it said to clean the area where the bsm sensors are, which I did. It still was malfunctioning so I did the next step in the manual, which was to take the car to the dealer. Estimate $250 on June 2 the problem happened again. The parking brake goes all the way up. We are taking it back to the dealer again to have it fixed.
