Thumping question - Smart Car of America Forums : Smart Car Forum

I noticed that after I start the car, the first 5 or 10 feet I drive forward, I hear a thumping or bumping. I feel it more than hear it actually. From the transmission maybe? Doesnt do it after that until I restart the car. I assume its "normal" but wondering what it actually is.

I've noticed the same thing.

I always back out of the driveway so I never hear it.

Its that body you thru back in the cargo area. Look, he's not dead. You have to hit him harder.

Are you talking about the self test of the ABS system? It is located near the front left tire.

....hummmm...same here...if you ever drove a front wheel drive car it feels like a CV joint going bad...

...Jefferios ...can you elaborate on that test....thanks

I'll buy the self-test explanation. Its always the same so I figured it was doing something like that. If it only did it now and then, I'd worry.

In my case, I hear/feel it right after backing up when I start going forward again.

Have it from the day one (feels like bad CV joint), I believe it is normal.

Guys. Same with our car until we started backing up fast and putting on the brakes firmly. This will reset the self adjusting rear brake shoes.

We now do this from time to time and the problem is solved.
