hi guys, i have a 2006 AT. i've noticed that whenever i start my car cold and begin driving, there's a strange noise coming from my engine bay around when i hit 2k rpm the first time. after the first time it goes away and doesnt come back until the next time i repeat this procedure. also, i've noticed that at the same time this happens, my brake pedal shakes. is this the car engaging the abs? does anyone know what this could be? thankss.

 

It's the ABS self test. Happens ~ 10 MPH or so each time you start the car. Perfectly normal and nothing to worry about.

 

whew sweet. thanks man.

 

yup my car and many others on here do that. weird sound/brake pedal twitch or vibration

 

thats weird. i wonder why it does that.

 

yea.. it does that sometimes.
