Mazda 3 Sedan Generations Ranked By Reliability

The Mazda 3 Sedan is Mazda’s entry-level four-door sedan, and with the Mazda 6 no longer offered in North America, it’s now the only sedan in Mazda’s U.S. lineup. It competes with other compact sedans like the Toyota Corolla and Nissan Sentra. Thanks to Mazda’s Japanese engineering, the Mazda 3 generally has a good reputation for reliability—but not every generation has performed equally well. In this article, we’ll review all Mazda 3 Sedan generations, looking at common mechanical issues and ranking them from worst to best based on reliability.

Our analysis pulls from a range of trusted sources, considering the number and severity of consumer complaints and recalls. Where available, we also reference J.D. Power quality and reliability ratings, which measure initial reliability rather than long-term performance. By combining these factors, we rank each generation from least to most reliable.

We’ve left out the 2022 and newer 4th-generation Mazda 3 Sedan because there isn’t enough reliability data available yet to give a fair assessment.

4. Second Generation (BL): 2010–2013

Highest J.D. Power Rating: 83/100 (MY 2010)

Among all Mazda 3 generations, the second-generation models are generally considered the most prone to problems. Produced from 2010 to 2013, this generation—internally called the BL—introduced a completely new front design. Its grille earned plenty of attention, with many comparing it to a smile, giving it the nickname “Mazda’s smiling grille.”

The 2012 refresh also brought Mazda’s new SKYACTIV engines, which have been used in all Mazda 3s since then.

Common Issues: Second-gen (BL) Mazda 3

• Clutch problems
• Powertrain issues
• Electrical issues

The second-generation Mazda 3 Sedans are among the most trouble-prone of all generations, both in terms of the number and severity of complaints, according to Car Complaints and NHTSA data. The 2010 models, in particular, have the highest number of recalls and consumer complaints in this generation.

Common issues include electrical problems caused by faulty control modules, especially the Transmission Control Module (TCM), which has led to multiple reports of drivetrain failures. Manual-equipped 2010 Mazda 3s also have a reputation for clutch problems, with many owners reporting premature wear or complete failure. Frustratingly, Mazda has not issued an official recall to fix this problem.

One report summed it up: “The 2010 Mazda MAZDA3 has the most overall complaints, and we rate 2010 as the worst model year based on repair costs and average mileage when problems occur. Clutch failures are giving owners headaches, and Mazda’s lack of support is only adding to the frustration.”

3. Third Generation (BM/BN): 2014–2018

Highest J.D. Power Tating: 78/100 (MY 2014)

The third-generation Mazda 3 Sedans fall in the middle when it comes to reliability and common issues.

Introduced in 2014, this generation was the first to feature Mazda’s “Kodo” design language, giving the sedan a sharper, more modern profile and a distinctive front grille. The i-Connect infotainment system also made its debut with this model. Engine options remained a 2.0L or 2.5L naturally aspirated four-cylinder, paired with either automatic or manual transmissions, both now equipped with SKYACTIV technology as standard.

Common Issues: Third-gen (BM/BN) Mazda 3

• Air conditioning/heater system issues
• Automatic transmission slipping
• Braking system/component issues (premature brake wear, handbrake failure)
• Interior accessories issues (infotainment system crashing, backup camera not displaying, keyfob not working)

Most third-generation Mazda 3s are quite reliable, with the main exception being the first-year 2014 models, which experienced some of the typical build-quality issues expected with a newly redesigned car, including the all-new engine. A few early models also had reports of automatic transmission slipping, though these cases were relatively rare. Air conditioning and heater system problems were a bit more common, but still limited.

A more widespread concern involves premature brake wear or occasional issues with the braking system, which even led to a recall by Mazda. While this generation isn’t inherently unreliable, considering the number and severity of complaints, third-gen Mazda 3s are generally only slightly more dependable than the second generation—something to keep in mind if you’re buying used.

As one official recall notes:
“Mazda North American Operations (Mazda) is recalling certain 2014-2015 Mazda6 and 2014-2016 Mazda3 vehicles. Water could possibly enter the brake caliper causing the parking brake actuator shaft to corrode and possibly bind.”

2. First Generation (BK): 2004–2009

Highest J.D. Power Rating: 76/100 (2009MY)

Among older Mazda 3 models still found on the used market, the first-generation cars have proven to be quite reliable, even more than ten years after production ended.

Known internally as the BK generation, the first Mazda 3 was offered as both a four-door sedan and a five-door hatchback in North America. It replaced the aging Mazda Protege as the brand’s smallest car until the subcompact Mazda 2 arrived. All models came with a four-cylinder engine from Mazda’s MZR series, paired with either a four-speed automatic or a five-speed manual transmission.

Common Issues: First-gen Mazda 3 Sedan

• Transmission issues
• Body/paintwork issues (corrosion, paint flaking off, water ingress)
• Engine issues (excessive oil consumption, coolant system failure)
• Engine, transmission mount failure

Most issues with first-generation Mazda 3s are simply due to age, as many of these cars are now approaching or exceeding twenty years old. It’s common to see minor body and paint problems, such as wear or clear coat peeling. Rust and corrosion on the body or chassis can also occur, though depending on the car’s location and maintenance history, it may not be a serious concern.

Both four-cylinder engines are generally reliable when properly maintained. However, parts like suspension components and engine mounts are considered wear items and may need replacement, especially on high-mileage examples.

Overall, the first-generation Mazda 3s from the 2000s are highly regarded for reliability. With regular care, these cars are likely to continue running well for many more years.

As one owner noted:
“Except for a minor issue with cracked motor mounts, the 2008 MAZDA3 is a fantastic vehicle with a great reputation. If you need to replace the motor mounts, first ask your dealer if they’ll cover it—these were addressed in a TSB and were recalled for some model years. Otherwise, aftermarket motor mounts work well; OEM parts may crack again.

1. Fourth Generation (BP): 2019–2021

Highest J.D. Power Rating: 81/100 (2022 MY)

The latest generation of the Mazda 3 Sedan is the most reliable of all the generations. Known as the BP generation, this version builds on the bold design of its predecessor and upgrades the interior with a more upscale look and a slimmer infotainment screen.

Under the hood, Mazda made several improvements, including better sound insulation, a more refined suspension setup, and the addition of a torque vectoring system. All-wheel drive also became available for the first time on the Mazda 3 Sedan, but only on the 2.5L turbocharged four-cylinder model after the most recent facelift.

Common Issues: Fourth-gen Mazda 3 Sedan

• Interior accessories issues
• Excessive oil consumption
• Body/paintwork issues

Being the newest Mazda 3 models works in their favor. Pre-facelift fourth-generation Mazda 3 Sedans have very few, if any, recalls, according to the latest NHTSA data. In fact, the 2018 Mazda 3 Sedan was previously highlighted as the least likely to cause problems, with the fewest complaints reported on CarComplaints.

The BP generation isn’t completely problem-free. Models made in 2021 with the turbocharged engine were part of a class-action settlement due to excessive oil consumption and faulty valve stem seals, while the naturally aspirated engines haven’t shown the same issues. It’s worth noting that models produced after 2021 may be more reliable, but since the fourth generation is still ongoing, there isn’t enough data yet to draw firm conclusions.

Summary: A Solid Track Record

Overall, the Mazda 3 Sedan has proven to be one of the least troublesome cars on the market, both in its latest versions currently on sale and among older models on the used-car market. Compared to rivals—especially more expensive compact sedans—it’s generally a solid, reliable choice. The most desirable models tend to be from the oldest and newest generations: the first-generation BK and the fourth-generation BP, which are both commonly found on the secondhand market.

As with any used car, it’s always a good idea to have a pre-purchase inspection or have a qualified technician check the vehicle thoroughly. This ensures the Mazda 3 you’re considering doesn’t have any hidden problems or a questionable history. If it passes inspection, there’s no reason not to consider it as your next daily driver.
