My park assist will not activate.  The message on the DIC just says "park assist off" every time that I toggle the switch (as well as when I start the truck). Anyone else have this issue?

Sounds like the system is being turned off while being told to be on creating the message. Did you

check the Park Assist setting in the menu to ensure it was not Off? You should not get the message with this option set.

Yes, I went into "settings" and made sure that park assist was enabled.  It was.  There is an issue with my system, that I am sure.  I am trying to figure out what that issue is.

Mine truck also does this. It started after an update. Before the update it would go off like crazy after the wash for 30 min or so. Alerting all directions back and forth. My wifes new Terrain also shuts off. Not sure how to tell when it is working again.

I’m having the same issue, if I go into setting and manually turn it off and then back on the LED light comes on for 3 seconds and then goes off. Please advise on how to fix!

new 2019 gmc sierra park assist not working, checked all settings, read manual, called dealer said need appt to check computer,

watched some videos on troubleshooting not much help, went out to truck with windex and papertowel, wiped all sensors and all cameras and presto park assist working just fine. had just driven down a wet dirt road 2 miles, sensors didn't look dirty but must be very sensitive. if you take your truck to dealer ,make appt and waste your time the dealer will say reset computer, or something, dealer gets paid for warr. call and tech gets his time, and all they will do is clean your sensors presto its fixed. hope this saves someone the trouble and time.

Washed my truck the day it got cold here. Got a warning park assist was off. Few minutes later it was back on but constantly going off on drivers side front. I wiped clean and saw no ice on the sensors. Really annoying in rush hour traffic. I was busy and unable to get to dealer, plus taking a few days thinking it may clear itself. A few days later the weather warmed up and it’s been fine since. 

I chalked it up to washing in the bitter cold.

This goes back to the NNBS, I have the exact same thing on my 2008 right after a wash, then it goes back to working whenever it feels like, its just a known issue happens on the SUVs aswell, poor engineering.

      upgrading speakers on 2026 std cab WT...

      By bwiese · Posted

      I don't wanna do major surgery/upgrades, behind-the-dash work, add amps, change radio etc. on my '26 std cab WT. On the WT, it has the base 7" IOR infotainment setup, and only two speakers (doors). Since I listen to classical, looked around for speakers that do well and dug thru reviews. Two-way speakers were found to be better than 3-way. So I've ordered a pair of  Infinity Reference REF-9632IX 2 way speakers.  [These may  or may not have been discontinued / succeeded by the 3-way ...9633 ones.]    These speakers are lauded for 3 ohm and 94db sensitivity spec so they'll work well for ordinary base car radios without amps and offer better performance (quality,  strength) than  default base paper-cone speakers. They'll be installed in a few days and I'll let y'all know what I think. Bill W San Jose

      Thanks!   Changed out the rear shocks today to Bilstein 5100s.  So far feel much better. The stock Rancho were wore out.  Lots of heavy hauling (2 moves, home renovations, etc).  Next up is new BFG tires Monday.  Cant wait the current tires have little to no wet traction and are super loud (hum)

      Correct way to service 2024 l8t allison trans?

      By Chuck FB · Posted

      How about I just point to the factory pans stand pipe little drain plug and claim its a pan with a real drain plug !. I just couldn't swallow the fact that a Dorman pan which at this point is probably the only pan out there that fits the gas version truck cost that much up here in Canada so I decided initially anyway to skip it and see what I thought of pulling the pan method and down the road if I felt inclined enough then I would either install a drain plug kit in the factory pan if there is enough room for it, or have a bung welded onto it, or put an aftermarket pan on. The thing is if the pan is not pulled then the magnets in the pan can't be inspected and cleaned or if wanting to change out the filter. However of course it certainly would make the job easier to be able to drop the oil first before having to handle the pan if dropping the pan that go around was the goal.    I knew a guy locally that was doing custom field spraying years ago with a pickup pulling a ground driven sprayer, I believe it was a GM pickup with an automatic trans. He had a drain plug in his pan and would drop the oil out of it once a week and top it back up through the dipstick tube to keep refreshing a portion of the oil often and that made the transmission last far longer than had he done nothing. Soft fields pulling 500 gallons of water at the start of each mixed up sprayer tank batch and in low range sucking along. I imagine he got some tips from other custom sprayer outfits doing the same thing at the time and learning from their blown up tranny mistakes. Transmissions then had no lock up converter so would cook the crap out of the fluid slipping that much and it would not have been synthetic fluid either.
