Accelerating on the highway passing a semi-truck when I lost acceleration power. Nearly caused a serious accident at highway speeds. Engine light then came on. After the incident the car's engine would stutter when accelerated above 2000rpm. Was able to bring it to a local mechanic who diagnosed both fuel pumps as damaged and replaced. Part was not inspected by police or insurance as it did not lead to a crash.

The infotainment screen in my Mazda3 developed a large spider crack in the corner. It's available for inspection upon request. It affects my ability to read information on the screen, and partially obstructs my backup camera's image. The problem has been confirmed by both the dealer, who saw the issue firsthand, and Mazda (see Service Alert No.: SA-008/18, issued 02/20/2018 - please note, the spider crack I have is much larger than the ones in the pictures in the Service Alert). There was no warning this issue was going to affect my car, it just happened one day.

- After filling up the gas tank and putting the cap back on, there is a distinct smell of gasoline until some of the fuel is used up. In summary, it appears to be spilling or leaking fuel/fumes when we fill up the tank. -This is a problem when parking our car in our garage and we are concerned that it could cause a fire. - We have not yet confirmed this with a dealer or independent service center nor have we had any other entity or person confirm this. - This issue was noticed recently and within the last year or so and without any alerts and/or warning lamps. - We understand that there is a recall on the Mazda3 for model years 2014-2016 regarding the ICV Valve (deformed gas tank) and even though it appears to be the same issue, our vehicle doesn't fall within the recall group. - Pl

Gas tank is leaking from the TOP. I could smell gas after a refill (and refilling a portable tank) that I thought must have been a spill I hadn't noticed, and the smell faded. But then it happened again at the next refill, and I knew it wasn't just a spill. Brought it to our trusted mechanic who said that the TOP of the tank was rusted out (wow!)(so, not from road salt) and needs to be replaced. Not cheap, but worse, I'd been driving around in a very hazardous situation that Mazda knows happens. No warning lights, no recall. Thanks, guys. Here's a thread about this being a common issue: https://www.mazda3revolution.com/threads/2014-mazda3-fuel-tank-replacement.245797/

Parking brakes will not hold car, even after adjusting the parking brake cable.

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.

Due to improper design of the rearview camera wiring harness fastener, my rearview camera image has been distorted and flickering for years. There has been no remedy for this issue for many years now and its quite dangerous to have a camera that doesnt work at all.

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. *tr

Tl* 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

The contact owns a 2014 Mazda Mazda3. The contact stated that while driving up an incline at an undisclosed speed, the vehicle temporarily lost motive power, and the contact became aware that the vehicle had failed to shift out of first gear.

Additionally, the contact stated that the instrument panel was functioning erratically, and the instrument panel lights frequently remained illuminated after turning off the vehicle. The check engine warning light was illuminated. The vehicle was taken to the dealer, where the failure could not be duplicated. The vehicle was then taken to an independent mechanic, where it was diagnosed that the head gasket seal had failed, w

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 goin

I initially had issue getting into and out of the 3rd and 4th gear (manual transmission car). I could feel gears grinding during shifting (with the clutch fully depressed). The dealer replaced the third gear. After the fix, the car now has difficulty getting into and out of gear 2 and 3. This problem is intermittent but is more noticeable after the initial start-up of the car, especially if the weather is cold (50f or colder). With the clutch fully pressed, I can still feel the gear rotating and grinding during shifting. When the car is cold, a lot of force is needed to shift the car into 2nd and 3rd gear. The shifting issue is less noticeable when once the car has been operating for 20mins. *tr

Around 68,000 miles, I began to hear a subtle whining noise coming from my 2014 Mazda mazda3. I was unsure where it was coming from and originally thought it was something to do with the tires. As time passed, the noise became louder, eventually to the point where I felt I needed to get it checked out. A mechanic told me it was something to do with the automatic transmission because the sound was emitting there. He explained to me that there was a technical service bulletin posted by Mazda that described the exact issue, and that's what he's sure it is. I got a second opinion from another mechanic and he explained the same thing. The cost to replace the transmission with a remanufactured model is somewhere in the ballpark of $2,000 - $3,500. The second mechanic I went to showed me the tech

On or about august 18th, I was driving through slow-down traffic passing the scene of a multi-car accident on highway 101 in san mateo county, ca at 35-40 MPH. Without warning, the moonroof glass exploded. (it was closed at the time.) there was no loud noise preceding the event, and no sign of any foreign object striking the car, nor among the debris. A week later, I had the glass replaced at putnam Mazda in burlingame, ca. I paid for the repair out of pocket (us$790.61). But in talking to the service rep, he confirmed that no outward cause for the failure was apparent. All gaskets and seals were intact and installed correctly, all mounting points were within tolerances, and the sunroof operated normally. The only sign of an issue was the actual broken glass. At this time I was told I was

Moments after driving my 2014 Mazda 3, I noticed the blue coolant dashboard icon was lit signaling the coolant is cold. As I drove without touching the accelerator, the car abruptly accelerated and I had to slam on the brakes so I would not rear end the car in front of me. Plus, I noticed the coolant dashboard icon turn off also. The cruise was completely off!
