09 sport automatic at 26500 miles, everything is AMAZING

The only thing I've noticed, which might be perfectly normal (i bought it used like 2 days ago) is when the car has been off for a while and i turn it on, it is completely motionless (good thing!)

but when i switch to reverse or drive as im pressing down on the brakes, the car sounds crazy as if its trying to push against the brakes and the whole car will shake.

After i let go of brakes, it stops but if i almost immediately after letting go press the brakes again, it will continue to shake.

HOWEVER if i were to accelerate for even one second and THEN brake, theres no shaking whatsoever and it doesnt happen again until the next time i turn it back on!

Just wanted to know what this could possibly be and if i should be worried!

Thanks anyone!

 

No need to worry. But you do need to have it checked.

 

I did some more testing and from what i can tell, it only happens whenever the blue cold symbol is on which explains why it only happens after maybe a while of it being off and goes away almost immediately

Any clues as to what this could be?

 

Ah, thanks

I don't have too much time right now but when i do, i will, just wanted to know what it was
