What Our Members Are Saying about the Reliability And Durability of the Mazda Mazda3

Mazda Mazda3 Reliability And Durability: Pros

2012 4dr Sedan 155-horsepower 2.0L I4
6-speed shiftable automatic FWD
It was neck and neck between the Mazda3 and the MINI COOPER. I had my heart set on the MINI, but reliability was the deciding factor. I spent countless hours researching vehicles over the last several months and was very dismayed at all the mechanical issues that plague the MINI. On the other hand the Mazda3 seems to be very much trouble free. I really wanted a MINI, but I knew its 'cool' fun to drive personality wouldn't be enough to overcome the reliability headaches I could expect. full 2012 Mazda Mazda3 review

I do have to hand it to this car; it's been DEAD RELIABLE. Nothing has been broken enough to warrant a trip to the shop. THe only issue I had was with the heater fan making noise, and then the heater stopped working at the end of last winter, but it is woring normally now, without a repair. full 2012 Mazda Mazda3 review

I've owned many great Mazdas in the past and they have always been exceptional cars, but this 3 has been awful. Everything was OK until around 70k miles and from there on out it has been nonstop issues.
  • Brakes - Plan on replacing rotors every time you do pads
  • Tie Rod - Broke clean in half at 80k miles. The car was never in a collision or anything that could have explained it. If I was on the highway I could have seriously crashed the car
  • Belt Tensioner - Only available OEM (and pricey)
  • Control arms, bushings (front and rear), constant clunks and thuds from the suspension.
  • Broken shock mounts
  • Heater Core at 90k miles
  • Wheel bearings - In 127k miles I have done all 4 twice. My mechanic says that this is common on all of the 3's he services.
  • Front End shimmy - It has had a shimmy of varying degrees constantly since about 50k miles on. I will get a bunch of front end work done, replace rotors, or balance tires, and it will be better, but never gone
  • All sorts of electrical weirdness (Sometimes the "you forgot your key in the ignition" chime wont go off until you turn the car back on/off)
  • Headlights - You will replace them so often that you can do it in your sleep. We also have a Mazda 5 and it is the same way. I have even had to replace the weird socket adapters they use. Currently I am getting no power at all to the passengers side. Also, those clear lenses haze like crazy.
  • Horn - even the slightest puddle drowns it. Mine seemed to have been shorted out as the relay trips but now I dont even get power to the horn itself
  • The condensate drain for the AC clogs constantly. If you dont notice it, it will slowly start to seep into the carpet and cause a wonderful mildew funk. Its easy to fix with a chopstick or pencil, but I have never had a car where this is an issue before.
  • Cruise Control now toggles off/on/off/on creating a wonderful seasick sensation
I would like to mention that I'm not some boy racer constantly hooning around. My car is completely stock, I'm a 38 year old dad, and 90% of the miles on it are highway back and forth to work. This is my daily commuter. full 2005 Mazda Mazda3 review

No major problems but there are still some problems with brake dust in the rear. Had to have the front passenger window fixed (got loose). Purge valve was found defective. Transmission 2nd gear shifted hard until the software was updated. full 2004 Mazda Mazda3 review

One rear shock started leaking at about 85k, which necessitated replacing both of course. The engine stumbles sometimes when accelerating from a steady criuse - can hear what I presum is the waste gate banging like a machine gun. No error codes and the Mazda dealership I go to has no clue as far as I can tell. I have been impressed with Mazda reliability but with many computers, differentials and complexity galore I may not own this one into late middle age. full 2007 Mazda Mazda6 review

Had a problem where the suspension would make a creeking sound while turning the steering wheel at slow (parking lot) speeds. Internet research turned up a few similar problems. Our problem was successfully diagnosed as a bushing problem in a lower control arm. I expect that I will need motor mounts replaced sooner-rather-than-later as well. full 2007 Mazda Mazda6 review

interior out of cheap plastic that easily scratches, seat foam partially collapsed, annual caliper lube required, bought the car as a 5year lease return w/ 84 000 km, now getting close to 9years 135 000km, replaced suspension bushings/ball joints from day1, clutch at 125k, no holes yet but plenty of rust, haven't been able to track down a couple of noises, might have been there since new, doing almost as much work on the car as on my 19year old 340 000km Volvo 850 though the Volvo is easier & more fun to work on, this Mazda isn't designed to receive any more than the most urgent maintenance with a design lifespan around 10years/250 000km, whichever comes 1st... full 2004 Mazda Mazda6 review
