Trailering App Gremlins

Tomato · May 17, 2020

Finally was able to get out and camp again, as some lakes have opened up around here for locals. Took my small trailer. All was fine with all systems on the way out (65 miles), but the trailer TPMS popped up LOW PRESSURE on the way back - about 10 miles in. Pressures were actually fine on the readout, and I verified all was good after stopping.

Started down the road again, and shortly thereafter noticed that the trailer mileage had gone backwards. Started watching it then - would go up a few, and then down.

Went in to edit the trailer profile when I got home, and the TPMS recommended pressure had changed from 50 PSI to 100 PSI which is what I have for my big trailer...

Not sure if anyone has had similar issues or has heard of a reprogram or fix...

Don't feed them after midnight, and don't get them wet!

Well, I have had my own issues with syncing trailer tires and having to remove the trailer profile because I would get service Trailer TPMS system message come up on the dash and the screen at that point it wont let you set up the trailer tire pressure anymore. So what do you do you delete the profile and make a new one. But I found out that every time you delete a profile it is really saved through onstar. You have to go to the GM App on you phone in the trailer section and delete the profiles. I had a hell of a time syncing the tires so I probably had about 15 of the same profile. I would look there and delete any profiles that your are not using. Mabey something is going on in that aspect because there are several profiles with the same name. Not sure if it will solve your problem but I figured its worth a shot.

Interesting...I just deleted the one I knew was not current, but I will need to connect my other trailer to ensure I delete its duplicate...I will report back if this works. Thanks for the tip!
