mine doesnt roll back

i have the 09 350

 

^^ Give it a steep enough incline and it'll roll back. Just like Wal-Mart!

 

Yeah mine rolls back on a very steep almost 50 degree incline. Dont ask me why I was on such an incline, but I was

The sucky thing is it rolls back, the car jerks itself to stop the roll, then it starts to roll back again, and I feel the gear box jerks again to stop it, feels like I am breaking the damn thing lol

 

It is listed in the specs of the car back on the 08's and I know mine has it because I use it all the time.

 

if i could recall, my first 1000 mile and 5000 mile service covered by the dealer includes this check. they're suppose to make sure it doesn't roll back on an incline. maybe you should give them a call

 

I tried this last night (didn't even know about this feature) and yes the car will roll back a couple feet then brake then roll back then brake also the trac light will blink.

Kind of a crappy design I think, shouldn't it just hold the car after the initial roll?

Oh well, I never used it before and probably will never use it again.
