Car shakes/vibrate when starting to move

david1504 · 02-02-2015, 05:44 PM

Recently I have been noticing some sound when I start driving, it always happens when I start to move by slowly giving gas, when it is on level ground it doesn't really happen, but it happens a lot when I start to move on a hill, the car shakes (feels and sounds like coming from the front wheels, but I am not sure), making a few clunks, but once I am over say 5-6mph it is gone. I let the dealer checked it and the report says:"customer may have heard loud engine noises " I was like wtf
Do any of you guys experience this, any idea what it might be?
Car is dct

Car has a "hill start assistant" function to assist in starting off on a slope. Could be an issue with that applying brakes too long? So, no error codes?

The intended function of the hill-start/drive-off assistant is this from the Supplemental Manual:

The drive-off assistant holds the car in
place for approx. 2 seconds after the
brake is released. Drive off without delay after
releasing the brake. Otherwise, the drive-off
assistant will no longer hold the car in place
after approx. 2 seconds and the car will start to
roll backwards.

If you're car starts to rattle off of first it could be your clutch.

Thanks for the input, it could be the hill assist, is there anyway to turn it off without coding?

Today I tested the car again and it shaked violently when I was starting to move on a hill, it did it for a second or so, it feels like the front wheel is on some slippery, bumpy road and the whole car jerks, steering wheel shakes as well, any ideas?
