    Owner Reported Trouble Spots

    The Reliability score is based on our latest subscriber survey of 2018 Mazda 6 owners. The owner comments describe problems respondents experienced with this vehicle.

    In-car Electronics

    Infotainment system (audio, GPS, phone), rear entertainment system, backup or other camera/sensors, head-up display.

    What Owners Say

    Android Auto

    ""Frequently fails to connect or start up properly or in a timely manner. Dealer has offered a firmware update, but with a disclaimer that sometimes in the middle of these updates, something can go "sideways' resulting in a bricked infotainment system. If that happens, because I am no longer under warranty, I would be responsible for replacing that system even though it would be their techs installing Mazda provided software at the Mazda dealership. Even with being told this is not a common occurrence, I cannot take the financial risk, so have chosen not to have this service done. I wonder why I should ever take my car - now out of warranty - to a Mazda dealership for service if they won't back up their work should something go wrong.""

    Anonymous A., BC (2018 Mazda 6 Grand Touring 2.5-L 4 Cyl turbo)
    Display screen goes blank

    "The display screen sometimes does not turn on when I start the car. I then have to restart the car to the screen to work."

    Anonymous, AL (2018 Mazda 6 Grand Touring 2.5-L 4 Cyl turbo)

    ""Display screen is randomly blank when starting the car. Sometimes it comes on after a while, other times it does not return until restarting. Also, the auto-brightness function does not always work.""

    Anonymous, NC (2018 Mazda 6 Grand Touring Unsure)

    Engine Major

    Engine rebuild or replacement, cylinder head, head gasket, turbocharger or supercharger, timing chain or belt.

    What Owners Say

    Engine rebuild or replacement

    "Sometime between 2020-2022 I was driving on interstate and the engine shut down and I had just enough power to pull over on the shoulder. Car was toward to my mechanic and was told I needed a new engine."

    Anonymous A., MD (2018 Mazda 6 Unsure Unsure)

    "Engine started leaking coolant and I thought it was leaking hoses. After replacing several hoses the mechanic found the head gasket was blown. The engine had to be rebuilt."

    Anonymous, AL (2018 Mazda 6 Grand Touring 2.5-L 4 Cyl turbo)

    Brakes

    Premature pad/rotor wear, pulsation or vibration, antilock system, parking brake, master cylinder, calipers, squeaking, brake failure, regenerative braking.

    What Owners Say

    Premature brake wear

    "All four sets of brake pads were worn to minimum thickness and needed to be replaced at around 53,000 miles. The car has an adaptive cruise system that utilizes the brakes in controlling the speed of the vehicle, so I am confident that is what caused the shorter than expected life span of the brake pads."

    Anonymous, MO (2018 Mazda 6 Grand Touring 2.5-L 4 Cyl turbo)

    Transmission Major

    Transmission rebuild or replacement, torque converter, premature clutch replacement.

    What Owners Say

    Refrigerant leaks

    "During an oil change stop at the dealership they noted a slow coolant leak and wanted $450 to fix it. When googling it seems like this is a semi-common occurrence with this vehicle. I had it repaired and since have gotten a letter saying they are extending the warranty coverage for this very thing."

    Anonymous, FL (2018 Mazda 6 Signature 2.5-L 4 Cyl turbo)

    Drive System

    Driveshaft or axle, CV joint, differential, transfer case, four-wheel-drive/all-wheel-drive components, driveline vibration, electrical failure, traction control, electronic stability control.

    What Owners Say

    Other driveline problem

    Anonymous, ON (2018 Mazda 6 Signature 2.5-L 4 Cyl turbo)

    Engine Minor

    Accessory belts and pulleys, engine computer, engine mounts, engine knock or ping, fuel leaks, oil leaks.

    What Owners Say

    Oil leaks

    ""So, on my last oil change they said the engine is leaking a little bit of oil. I said this seems strange for a car with only 40,000 miles and they said this is "normal" for turbo engines because of the higher pressure. Normal for an engine to leak oil? Hmmm""
