Park Assist Off

Park Assist Off

Postby 1SLOSHD1 [OP] » Apr 26 2012, 4:26am

Forgive me if this has already been answered, or posting in wrong category. New 12 GMC Sierra and occasionally when put in reverse "Park Assist Off" beeps and is displayed in the DIC. I have nothing in to the hitch, and am just wondering if anyone else out there has experienced this.... not wanting to go to the dealer if can be avoided.

I've never had it happen without a trailer behind me, but mine sometimes is a pain to turn back on. It will keep saying park assist off and I have to stop put it in park then turn it back on.

Only time mine is off is when I'm hooked to a trailer, no other issues. Has it always been like this? Maybe you have a bad fuse somewhere?

Mine occurs at low/slow speed usually when backing out of driveway and parking spots with nothing around or behind me. Sounds like I may take it to the dealer next week and see what they say, maybe there is a flash out for this or something. Truck is only a month old !!

Mine does this sometimes too. Nothing in the hitch and tailgate up. Even when it's perfectly clean it'll do it sometimes. I don't know why it does it though.

Happened to my 2007 and I cleaned the sensors on the bumper with some rubbing alcohol and it stopped the next day and hadn't had a problem since. It also did it when snow covered the sensors...hope you find a solution!

Anyone resolve this? My 2011 does it a lot it seems when its just cold. Did it again this morning. Not a bit of snow or grime covering the sensor. I put it in reverse and get a fast beep with no message on the DIC, then after a pic it will say its blocked. It isn't blocked or even dirty. It's garage kept, so I know its not ice on the sensor.
