Every so often (not very frequently), I'll come to a stop at a red light or stop sign or wherever, and immediately after stopping, there will be a very brief rumble/vibration felt underneath the car that only lasts for a second or two. It feels like it's almost underneath the driver's seat. Has anyone else experienced this? Would any of you guys happen to know what it is? Thanks....

what are your RPMs doing at that point? are they dipping? mine is doing that as well. im thinking it might be fixed by the transmission reprogram. mine is a 2011 and dont think its had it performed yet.

Unfortunately, it happens so quickly (and relatively infrequently) that I haven't been quick enough to look and see what's going on with the RPMs. It's basically a very quick shudder that lasts for maybe 1.5 seconds. I'll be going within the next week or so to have the latest TCM update applied to my car, so we'll see if that fixes it...

It could be all the parts you removed
To save gas

Transmission reprogram? What were the symptoms and is there a way to tell if that's been applied? I've been having some odd issues during braking (sometimes) that I think is related to the transmission.

this looks like it, and could be my problem: http://x.infinitihelp.com/forum/showthr ... 10291.html
