The dealer insisted this was because the rotors were heavily rusted due to not being driven enough. It sat for 3 weeks in April during the first lockdown( like everybody elses cars) but was driven frequently during May/ June and twice weekly prior to the lockdown. My husband found no excess rust when he changed the tired during the lockdown.

Very cold day to be awaiting a tow so continued the last couple of miles. Battery was diagnosed as faulty and replaced.

Mazda Mazda3 in Massachusetts, United States May 2017 - Jan 2022
Feb 2018 14000 mi	Exterior trim panels between the driver side door and rear passenger door are melted at the top 4 inches. The dealer would not repair under warranty, and stated Mazda will not replace it since trim is not covered. They told me to contact Mazda corporate to see if they would sell the parts at cost. Dealer price would be $200 for just the two plastic panels and me installing them at home. This was probably caused by a reflection from a building window onto the plastic trim. passenger seat belt warning light would intermittently come on even when no one was in the seat. Only way to stop the warning was to click the seat belt. The seat sensor seems to be very sensitive to anything on the seat including just a pen or tissue box. No fix.

Mazda Mazda3 in British Columbia, Canada May 2017 - Jan 2022
Jan 2022 32240 mi C $717	The shifter button was getting stuck. When stuck, the car cannot turn off properly because the car won't turn off in gear. This happened and drained the battery. Both the battery and shifter required replacement (the battery may have need to be replaced from general wear and tear within the next couple years anyway, but this killed it slightly premature). It's not a true transmission problem, it might be considered trim.

Another power door lock actuator replaced, but they're ALL noisy at random intervals. Crap design maybe? Squeaky and noisy and sound like utter trash.
Sep 2017 23560 mi	Infotainment still demonstrates laggy, glitchy, and overall poor performance. I've given up on trying to get the system to perform as it should and have just accepted that it's garbage. All four power door locks squeak and groan intermittently when locking.

Apr 2018 40000 mi	About a week after I bought my car as a certified pre owned I noticed that I was able to lift the front driver and passenger seats up with my pinkie. Doing so exposed the subframe of the seats below. I brought the car to another dealership besides the one I purchased the car from and they replaced the seat cushions for both the driver and passenger side free of charge. I was able to see a copy of what they were to bill Mazda corporate and it came out to around $400 covered by the warranty.
Dec 2019 63000 mi	I randomly checked my coolant level on a cold Christmas Eve and discovered my coolant level was extremely low below the low fill line on my coolant reservoir. This car has been dealer maintained as its a CPO, and according to my paperwork the coolant level had been checked by the dealer 2 months prior. Fearing a coolant leak I had the dealership perform a leak test and none was found. Additional coolant was used to top off the level and according to the service dept the temperature drop caused the coolant to contract. This inspection was completed free of charge.

Mazda Mazda3 in Vermont, United States Jun 2017 - Jul 2022
Jul 2017 34000 mi US $60	Friday afternoon developed sudden rear brake grinding noise, intermittent. Removed tire for inspection. One brake pad was completely worn away, the other pad was fine. Auto store gave us the wrong pads, need to go back today. Will be calling auto dealer on Monday concerning brake issues. Had the same issue with my 2014 Mazda 3. 8.10.17 update: My dealer replaced the pads and rotors and did an 'upgrade' in the middle of July. Today I received a call from a customer service rep from the Mazda Corp. He informed me that there was now a new TSB on the brake issue and a new redesigned caliper support. My dealer had been informed and all I have to do is bring the car in for the new fix. I am happy with the response from Mazda.
Jul 2018 64000 mi US $40	On going issue. 'Fix' that was applied to my rear brakes last July 2017 was either bs or failed. Started to hear a noise from the rear brakes Sunday morning. 30,000 miles since the repair paid for by Mazda. BF checked them out. Same problem as July 2017 and on my 2014. The outer pads were worn down to metal and the inside pads didn't even show wear on the indicators. I am pissed. I specifically asked the head of the maintenance department at Autex Mazda in Keene, NH to have the technician check out the wear on my brakes when they replaced my tires on my visit on 6/19/18. I was told that I had a little life left in the brakes but the wear was even, that I did not have the issue that I did last time. They out right lied to me. I have the pics to prove it. Mazda made changes to the brakes with the 2014 model and never fixed it. I contacted the Mazda Corporation again. Not sure if they will respond, but I am done with Mazda.
Jun 2021 141000 mi US $100	Every year the brakes need a either the rear pads replaced or the entire brakes need to be redone. The rear pads always, always have uneven wear. Inside pad is down to metal, outside is like new. Every year, with ~ 25-30,000 highway miles, very little stop and go. Whatever Mazda did to their brakes back in 2014 really messed things up. This car is now a back up car.
Jul 2022 165000 mi US $105	Replaced brake pads and frozen calipers.

They replaced some bushings and did a TSB modification to the passenger side and drivers side. However after having the car a couple days the car had to be taken back to dealer due a new noise from the front end that sounded like grinding or creaking noise. The dealer said the had to re-torque some loose suspension components and was very vague. The car drives fine and I still love it but the steering wheel is now not completely straight.

They didn't say it was covered under warranty. Since the oil wasn't dripping and the oil level wasn't going down, I declined to have the repair done. I returned to the dealer after the warranty was up (just after 50,000 miles) and the dealer said they would fix it under warranty. They said that the hydraulic tensioner for the serpentine belt was leaking. I told them to fix the slight leak in the cam chain cover, and also replace the hydraulic serpentine belt tensioner, and replace the serpentine belt while they were at it. The replacement of the hydraulic serpentine belt tensioner and the new serpentine belt cost me around $210.

May 2018 82000 mi US $700	Car was idling roughly and had occasional problems cranking up. Like it would take longer to crank before the engine fires up. It almost sounds like the enginr was choking before starting up. Car would idle roughly but only after the engine has warmed up. Dealership did not diagnose the car, but suggested throttle body and intake valve cleaning, valve cover and spark plug replacement. The idea was these services would fix the problem. After having all of those done, the issue with idling roughly has gradually gone away. It doesn't seem to an issue anymore, today is like 1 month since the car was worked on. The car still has the occasional issue of trouble starting up. Same symptoms, it takes longer to crank before the engine fires up. Only seems to happen when the engine is warm, has not ever happened yet on a cold start. I am working around this issue by stabbinh the gas pedal as soon as i notice the car taking longer to fire up.

I have yet to determine if the noise is coming from the end links or the shock absorber assembly, which was a pre-manufactured unit that I don't love. The sound is clearly coming from the front right wheel well, which is why I do not suspect the bushings.

Sep 2015 63000 mi US $120	HID Xenon headlight burned out, so replaced them both, but that required removing the front bumper cover and the headlights. The HID headlight bulbs cannot be replaced unless the headlight housings come out of the car. Regular headlights on regular Mazda 3s do not require such dismantlement and can be converted to LED headlights.
May 2018 110000 mi	Plastic mushroom around the hatch release button, located in the center of the hatch, cracked apart and would not hold the release button in position. It fell inside the hatch. I took the interior trim off the hatch to take a look. I used some duct tape to tie it into a workable position so that it would not fall back into the door when pressed or via normal driving vibrations. It wasn't really a fix, but it was just a hack/bodge to continue using the hatch until I could get a fix. THREE recalls exist on the vehicle at this point, and I was never going to have time to deal with them at the dealer. The driver's seat slider recall (applicable 100%), the hatchback lifters (recalled but mine were okay), and the dashboard lifting off the gauge pod (a cosmetic problem). Additionally, the turbo was starting to go. I'm sure the dealer putting the wrong oil into it twice (0W20 instead of 5W30 or 5W40) probably helped it along to its death. I'm not going to have time to deal with the dealer or a shop to replace the turbo, so I've traded the car in June. Somebody will get a rare and otherwise lovely MS3 that needs a turbo. It's really a blast to drive.

Mazda Mazda3 in Illinois, United States Sep 2012 - Oct 2020
Jun 2017 62000 mi	After I had new brakes put on I started hearing a humming noise driving home front the right front. I had never heard this noise before (I'm the type of person who pays attention to their car). Turns out they had to use a sledge hammer to break the brake front discs free due to corrosion. The dealer didn't admit that this caused the bearings to go bad, but replaced them for free. After they replaced the front bearings, I started noticing a clunk from the left front suspension backing out of my garage. Once again, I had never noticed this in the 7 years I've had my Mazda, but it started the day I got back from the dealer. They then replaced the whole left front control arm due to a loose ball joint. After this I noticed the new right front rotor was wearing differently than the right front rotor. Hawk Mazda thought it was "normal" wear until I convince them the pad was seized on the rotor (which it was). Moral of the story, don't go to Hawk Mazda in Joliet, IL for service. I honestly think their wasn't anything wrong my Mazda until I brought it into the dealer, I don't believe in coincidences like that. Thanks for checking in.

Mazda MazdaSpeed3 in California, United States Jul 2010 - Feb 2022
Feb 2018 71000 mi US $90	Strange loss of ignition while driving, just for a split second, then ignition returns. Happens mostly during slight right turns, when right turn signal running. Very hard to reproduce, but happens more frequently at night when lights and other electrical on. Mechanic thinks it's in the steering column where ignition wiring and modules are. Haven't fixed it. Just trying to analyze exact cause. Must reproduce at-will to fix. Have to take out steering wheel. Too much hassle at the moment. Will diagnose over time. Car runs pretty much great except for those sporadic loss of ignition like the car goes off the "on" position. Not related to the ignition slot or key. Can pull and push on it with no effect. Not weight pulling key downwards either. Mostly when steering wheel is slightly to the right and right signal running. Very strange.
Mar 2018 72000 mi	Very intermittent problem. While driving, getting very short periods of hesitation, total ignition failure and lighting off but ONLY for a split second, then it returns to ignition and all electrical running and keeps going with no issues. Seems like a bad ground issue that only occurs under certain conditions and movement. Gets worse in rain/wet conditions. Very difficult to troubleshoot. Seems like an issue in the steering column/ignition circuit, and generally happens more when the headlights are on. Very short period of single loss of total power, for milliseconds, hesitates and then comes back on like nothing ever happened. I just hope it's not in the ECU or a connector to the ECU. This will take time to troubleshooting. Will post updates. Doesn't happen very often, maybe once a week. Will first have to tighten down all ground wires and go from there.
Jun 2018 75000 mi	The turn signal function is INSIDE the ECU for this car. I believe that the problem is due to a bad ground somewhere as the only time I lose occasional ignition is when the turn signal is flashing and other loads happening (or so it seems). I added more grounding wire to hopefully eradicate the issue as I believe it's due to an intermittent bad ground state. Also reconnected the ECU to see if dirt / capacitance build up may be an issue. The turn signal flasher (controlled by ECU main computer) is what causes the ignition grounding most times. I am still guessing, but hopeful it's "just a bad ground" and not the ECU itself. Intermittent and the ignition comes back on quickly in just ONE time at the beginning of the first flash... After that it doesn't do the ignition shut-off more than once and the car recovers quickly, even at-speed. Very little momentum loss just a "flicker" like a reset.

Aug 2013 53000 mi	Every 20K miles the Mazda chews thru tires. Tires that are warranted to 60K. Finally after 3 alignments in 5 years, a mechanic tells me the front suspension probably came out of spec from the factory and cannot be fixed. Passenger side seatbelt connector rattles every time the temp drops below 40 degrees F. Connecting belt to it or stuffing things down between seat and connector doesn't help. DRIVES ME NUTS! When passenger side window reaches top there is a loud "snap". Other owners report similar issue. No repair. It happens randomly so not too worried about the issue. 3/29/11 Dealerships says clicking from front wheels under torque and clicking front passenger side seatbelt connector are "operating as designed." reported bass drop at 34/35 on radio. Original dealer delivered car when new even though this radio/changer was on recall. Just a quirk now. Not interested in repairing. Also, light on cig lighter fails at times. part not in stock. Rear end started making a rattle/jangle noise when hitting low speed ruts. Body on driver's side has dropped. Haven't yet found the issue. car is only 5 yrs old and 53+K on the odometer.

Feb 2017 121520 mi C $129	AT warning light on /off intermittently. Electronic solenoid sticking in transmission, and transmission needs to be replaced. Replacing with rebuild estimated at $5K or so. Two Transmission related CELs stated on diagnosis report.
Jun 2017 123380 mi C $625	Replaced the old TCM (Transmission Control Module) with a newer version. A CEL and AT light were intermittent - The transmission would go into 'safe' mode and would not shift properly, or it was a harsh shift 1st and 3rd gear only. Shutting the engine OFF and a restart would sometimes cure the problem. This is a common problem with this car, and can occur anytime. AT warning light on /off intermittently. The dealer wanted $5k to rebuild the transmission. Studied a lot of Mazda forums on the internet, and determined the problem was the TCM, but a replacement part from the dealer was $750.00 + HST and labour to install it. I managed to get a new current one from Scarborough Mazda for $550.00 + HST and 2 hours of my time to install it - plug 'n play. Problem solved - it ran and shifted like a brand new car! Mazda has to be aware of the TCM problem by now, and should have issued a TSB to cover the situation, so dealers and their technicians could accurately diagnose and repair this obvious 'long term' reliability issue.
