    Default 2011 mazda 3 2.0 sedan, noise coming from rear passenger.

    Hello guys, I have 2011 mazda 3 sedan. 2.0. 85km on it, Ive been experiencing this noise coming from my rear passenger whenever i am accelerating at any speed. i cant describe the sound but seems like a plastic that got stuck or something. checked my rear seats and trunk might something be stuck on it like plastics, or any material but did not found anything.It doesn't affect anything in terms of handling and performance of my vehicle yet but its really annoying. Sound goes on and off. any1 have experience thesame issue as mine? let me knw thanks

    Noise coming from rear passenger when accelerating... hmm. Well Mazda3s are surprisingly quick, which can surprise passengers a bit! But if the passenger becomes too annoying just tell him/her to get out and walk. Should fix your problem.
    Canada gave us rust and DRL. Thanks for nothing Canada!

    Is it a tapping type noise? or a rotational one?

    Could it be your tire? When I switched to 18" wheels and tires there was a substantial noise coming at higher speeds.

    I get a knock knock , kinda rotational at low speed when going slow over bumps.
    I thought rear stabalizer endlinks maybe loose and undone and bar is tapping.
    Actually they needed replacing and put one a heavyduty set from whiteline
    but noise was back ...I think now its associated with the damper going up and down over bumps or speed bump.
    If its not that ... raccoons squirrels drunk and banging their heads together....

    Possible wheels bearing too.

    Check your shock mounts and/or your trailing arm bushings.
