Rear Parking Assist Symbols Unavailable

kelub · October 7, 2013

I've had my truck about 10 days now, and one thing I noticed from day one is the backup camera/system complains that the rear parking assist is unavailable. My wife's 2014 Traverse has the sensors in the bumper that allow the system to know if something's close by, and then does the "beep beep beep" thing with the visual exclamation point on the screen. I don't have any of that - I assume by design.

So that's all well and good. On the MyLink system, I go to Home -> Settings -> Vehicle -> Collision & (something) -> Park Assist. There are three options: off, on, and on with towbar attached. It defaults to on. And therein lies the problem.

I believe, as does my dealer, that the problem is the software is trying to use the park assist software, but there's no park assist hardware for it to communicate with. No matter how many times I switch it to "off", the next time I turn the truck off and on again, the default goes back to "on." The DIC also chimes in with "Park Assist Temporarily Unavailable" during this time. I can dismiss it, but the "Rear Parking Assist Symbols Unavailable" message is white text on black background, boxed out at the top of the camera screen, taking up a good 1/6th or so of the screen real estate.

I had the truck at the dealership this past weekend to get the bed liner and LED lights added and they were going to look at this issue, but ran out of time to get to it. I need to reschedule, but was hoping maybe there was some other option I'm missing, like a "Don't default to factory settings every time the truck is started" option I'm just not seeing. Also curious if anyone else has had this problem.

Hi. Did you ever solve this? I'm getting the same error message on my 2015 Sierra. Thanks.

I also had this and once I gave the rear sensors a good cleaning it has never happened again even when dirty now. Possibly a coating from building/ shipping for protection that needed to be cleaned off?

just noticed a 2 year tread bump
