Steering column doesnt always go down
Sometimes it goes down and sometimes i have to use the adjuster to bring it back to my preferred position..
any ideas?
at first i thought something inside is broken, but now im thinking it has to do something with modules because before i didnt have this happenin

I had similar issues a year ago. Sometimes it would work, other times it won't unless I manually move the adjuster up/down many times. I thought maybe it was corroded contacts or something with the switch.
Took it in to the dealer, they told me there's a plastic "Bone" like piece inside that has tendency to break. When it breaks it sometimes causes the motor to jam. They ended up replacing the whole motor assembly. It was under extended warranty so no cost.

had a similar experience with easy entry / exit system... where it would work only intermittently... dealer advised they reset the system and all worked again... for about a month... then same issue presented itself, only this time no tilt function at all... dealer then replaced tilt / telescope motor... all has worked since... so i suspect the motor may going out...
does the tilt / telescope function work every time you manipulate the manual controls? are there any odd sounds it makes when it is working?

Really odd , but mostly happens when i park the car in the morning and then after a work day when im
about to drive home , it does it.
on short trips it works no problem.

^ ^ sounds much like the intermittent function i experienced... which turned out to be the motor... i guess the only way to know for sure is to have a dealer test / troubleshoot - unless you know of some way to test / diagnose the motor function... any warranty left on the car (perhaps extended)?

On my car, the steering wheel just stopped moving up/down period. Took it in under warranty, and literally the writeup I got back on the service report was "motor seized, hit with hammer numerous times, started working again". I'm not kidding. THIS WAS FROM THE DEALER.
