hey guys,
this is my first post if it is not clearly stated please forgive me lol. I own a 2013 mazda2(automatic) and now is about 35000 mile and there is a problem that has been bothering me. when my car is stop at the stoplight (foot on brake) there is some strange noise and my car sometime is kinda shaking, but if i pull my handbrake or put it in neutral the noise is gone. so i did some research, and lot of people say is idle problem. i am wondering if there is any mazda2 owners have experienced this problem and get it fix ? and is it under Mazda warranty ? if anyone could help please let me know ... thank you so much !!!

 

Maybe the idle speed is just a little high. The idle speed is regulated by the electronics. If there is anything that makes the normal low idle speed too low the electronics dials it up. So the speed is high enough to put a bit of force through the torque converter and you hear and feel the engine vibrations more.
At 35000 miles your car may be due for a tune up. That should take care of it.

 

Warranty is 5 Yr / 60,000 Miles on Drivetrain. Tune Up, brakes not covered on warranty. However there is a 3 Yr / 36,000 Miles Warranty that you might get some stuff covered (arguable as brakes are a wear item).
Without a Cel (Check Engine Light) any engine warranty is unlikely as it is within specs!
If noise is brake related, good luck with warranty !
