Kestrel Take
Second year of the third-generation Mazda6 — the 2.5L Skyactiv engine and a conventional six-speed automatic, which is why it holds value against CVT-equipped rivals. Sixty complaints is a modest record and a quarter of it is one recall: the parking brake actuator in the rear calipers corrodes and binds, and owners spent 2017 waiting for parts. Eight transmission complaints describe the car dropping to neutral or locking in a low gear with an AT warning, one ending in a crash — few, but the kind you test-drive for. Seven owners say the windshield cracks from small chips. Confirm all three recalls closed on the VIN lookup and drive it long enough to get the transmission hot; a car that passes is one of the better midsize buys at this price, and we say that having read every cluster on the record.
What we checked
Reconciled against public records, 2026-09-25
NHTSA holds 60 owner complaints for the 2015 Mazda Mazda6, and 3 recall campaigns.
A big number here usually means a lot of these were sold, not that it is a bad vehicle — popular models collect more complaints for the same rate of trouble. So the total on its own says little. What is worth reading is the shape of it. The largest single group is the brakes at 25%. That is notable without being overwhelming — worth checking, not worth panicking about.
3 recall campaigns cover this model year. Recalls are repaired free, for any owner, with no time limit on most safety campaigns — but only if someone books it in. Ask the seller to show it was done, or have any dealer check the VIN; it takes them a couple of minutes and costs nothing.
Counts come from the NHTSA complaint and recall database — free, public, and worth checking yourself.
Known Issues for the 2015 Mazda Mazda6
Ranked by wallet impact. These are documented, recurring problems — not freak accidents. How we decide that.
Recall 17V393 covers 2014–2015 Mazda6s with the cable parking brake: water gets past the caliper boot, the actuator shaft rusts, and the parking brake either will not hold — a rollaway risk — or will not release, dragging the rear brake until it overheats. Dealers inspect the shafts and replace corroded ones free. Fifteen brake complaints on this year and most are about this recall, including owners who felt the fix did not take. Outside the recall, a seized rear caliper is a few hundred dollars a side. Pull the parking brake hard on a slope and release it; then drive a mile and feel the rear wheels for heat.
Repair cost: $0 with the recall — verify it was performed; $300–$800 per rear caliper if it has seized since
Source: NHTSA complaints filed under the brakes (15); 3 NHTSA recall campaigns on this model year.
Eight power train complaints, and the pattern in them is electronic rather than mechanical: the car goes into neutral at 35 mph with an ATS or AT warning on the dash, the engine races, then it slams back into gear; or it sticks in a low gear until the car is restarted. One owner's daughter crashed after the car lost power. The Skyactiv six-speed itself has a decent reputation, and these read like a control-module, wiring or solenoid fault — cheap to fix if diagnosed, expensive if a shop replaces the whole unit. Drive it 20 minutes until it is hot, then do a few stop-and-go pulls and a highway downshift.
Repair cost (estimate): $150–$600 for a connector or solenoid; $3,000–$4,500 if a shop replaces the transmission — about 39% of what this car is typically worth
Source: NHTSA complaints filed under the transmission and drivetrain (8).
Seven visibility complaints: cracks that spread from a tiny rock strike, a crack that appeared in a parking lot, and one sunroof glass that shattered at highway speed. Owners believe the glass is thin. A replacement windshield on a car with the windshield-mounted camera for Smart City Brake Support needs recalibration on top of the glass, which is why quotes vary. Sight down the glass at the car for chips and edge cracks; a cracked windshield is a negotiating point, not a walk-away.
Repair cost (estimate): $300–$900 per windshield, higher with camera recalibration
Source: NHTSA complaints filed under glass, wipers and mirrors (7).
Recall 14V173 covers 2.5L Mazda6s with the i-ELOOP regenerative braking system built May 20 to December 4, 2013 — early production, so check the build date. The PCM can wrongly decide the charging system has failed and stop charging; the battery drains, acceleration fades, power steering and wipers can quit. The remedy is a PCM reflash. Free and quick, and a car that has had it will show the campaign closed on the VIN lookup.
Repair cost: $0 with the recall — verify it was performed
Source: 3 NHTSA recall campaigns on this model year.
Recall 14V675 covers Mazda6s built October 2012 to October 10, 2014: the TPMS compares tires to each other, so four slowly deflating tires never trip the light. The remedy is a software update, free at any Mazda dealer. Worth confirming and then ignoring — check the tires with a gauge on the day you look at the car anyway.
Repair cost: $0 with the recall — verify it was performed
