Anonymous, CA (2017 Mazda 6 Touring 2.5-L 4 Cyl)

In-dash navigation system (GPS)

Jean-Guy L., QC (2017 Mazda 6 Grand Touring 2.5-L 4 Cyl)

"Very slow loading when car is started up."

Anonymous, MA (2017 Mazda 6 Grand Touring 2.5-L 4 Cyl)

Anonymous, MD (2017 Mazda 6 Grand Touring 2.5-L 4 Cyl)

Anonymous, CA (2017 Mazda 6 Touring 2.5-L 4 Cyl)

"does not initiate calls correctly from bluetooth. Must initiate calls from phone. May be a problem with my phone--other phones have worked better than my phone."

Anonymous, GA (2017 Mazda 6 Touring 2.5-L 4 Cyl)

Eric F., CA (2017 Mazda 6 Touring 2.5-L 4 Cyl)

Anonymous, CA (2017 Mazda 6 Touring 2.5-L 4 Cyl)

Fuel gauge/sender

"Sometimes, particularly when it's cold outside, the dashboard fuel gauge gets stuck. It doesn't move on the two places on the dashboard that should indicate how much gas you have left in the tank - or how many miles you've driven on the gas in the tank since you last filled it. It eventually starts working again - usually after several miles. It's a big job to fix it, but I plan to bring it back to the dealer to be repaired."

Brakes

Antilock system (ABS), parking brake, master cylinder, calipers, rotors, pulsation or vibration, squeaking, brake failure or wear.

Premature brake wear

"Rear driver side pads wearing at an irregular rate especially in relation to other wheels. Thinner rotors require replacement at lower mileage."

Bob D., NY (2017 Mazda 6 Touring 2.5-L 4 Cyl)

Pulsation or vibration

"Brakes have significant pulsing and vibration issue. Rotors were resurfaced, but the problem returned within a thousand miles. Seems to be a common complaint about Mazda 6 brakes."

Robert C., CA (2017 Mazda 6 Touring 2.5-L 4 Cyl)

Body Integrity

Squeaks, rattles, wind noises, loose or cracked seals and/or weather-stripping, air and water leaks.

What Owners Say

Air or water leaks

"The sunroof is essentially useless. When the sunroof is opened, leaves or other debris collect in drain channels. The debris causes water to leak into the interior and also causes condensation to form on the windshield."

Anonymous, (2017 Mazda 6 Touring 2.5-L 4 Cyl)

Squeaks or rattles

"Beginning just before the 20,000 mile mark, the car has started to make a mysterious whirring noise. It sounds similar to muffled fan noise, but persists even climate control off. I've also tried unplugging all accessories in case it was an interference but that did not resolve the sound. I am worried it may be the valvetrain, because I can hear what I think is the same cadence underhood as ticking."

Alexander P., OH (2017 Mazda 6 Grand Touring 2.5-L 4 Cyl)

"The problem has been there ever since we bought the car. As I mentioned previously the vibrations were more noticeable at freeway speeds. We have done everything as recommended by a local Mazda Dealer including replacing wheel bearing, lower control arm, road force balance all wheels, rotate all wheels. All these repairs reduced the vibrations but did not eliminate them altogether."
