Per the dealership, "new part is in, all the codes are gone, but now we can't get OnStar to work/connect with the car, awaiting tech support from GM'... The saga continues... Slowly researching California lemon laws, looks like they have 30 non consecutive days. So far they are at 7 days, I got to drive the car for 6 before taking it to the dealer.

Sounds like they're guessing, and throwing parts at it. i agree with a previous post, in that, it sounds like the car wasn't fully PDI'D. I bet the Constar didn't work before either. Don't scrap the vehicle because they're inept. If possible find another dealer who would be willing to look at it. You might get lucky and find a Tech that knows what he's doing. I was also thinking... Did they get something too wet when they detailed it? Might just be a bad connector (as has been stated) Stay on them, you spent a lot of money. Don't fall for the BS. You should be talking to the service manager or service director. Not an advisor, most don't know about repairs. Just selling service... I know i was one of the ones that could also fix cars. Good luck!!

There might even be some over the air update that may resolve the problems as well.

There are over the air updates? Are these the updates where the dealer will tell me to press the onstar button and 'check for updates' or is this something else?

Thanks!!! I've actually felt pretty supported by the dealership thus far. They put me in a Sierra loaner car right away and have been checking in with me daily. I've got both my cars service advisor and the general manager (who also overseas service) checking in on me.

Its unfortunate that the car has been out of commission but I can't pass much/any blame on the dealer, especially since it did it as I drove the car home. Car has 150 miles on it when I bought it, but 90% of those came from moving the car from another dealership to my dealership (My dealership traded for it). In the end, I think they'll do me right... Just frustrating not having the new family hauler.

I don’t think this is the case, based on the fact that the dealer is engaged w/ the TAC (technical assistance center) at GM. I get the OP’s frustration, and it shouldn’t happen. That said, it’s a machine, designed and made by man. It isn’t perfect and neither are we. I always say, “stuff happens. It’s what happens after stuff happens that matters.” The dealer is stepping up; so due to that, OP is pretty satisfied.

To the OP. The up side of this experience is that you are building a relationship with key personnel at the dealer; and trust and those relationships will enhance your ownership in the long haul. Hope they solve it soon. Let us know how it ends!

The speed limit sign is part of the info from OnStar data. The data comes from att and is not solely part of the gps program like the old system. So if the vehicle is in an iffy area the speed limit sign drops off.
To me it seems like the gps program from google is faster than the att data. Or the att signal is lost.
I’ve lost that sign in places where I expected to lose it. Ie parking lots but have also lost it on major highways in the north east. Ie NJ Pa and NY where I didn’t expect to lose it

My 21 Tahoe HC requires data plan (AT&T $10.00 per month) to keep the connection with all things wireless to function. Onstar tired to tell me they would provide the connecttion for $25..PFF. Not happening onstar!

Not exactly true.

The Data comes from the Offline Maps data that is downloaded to the infotainment screen. Normal google maps apps (be they iOS, Android, or even PC/Mac/Chromebook) allow you to download maps for offline use, and they have a 12 month expiration. The GM system seems to be set to about a week, then your offline map expires.

So, you don't get maps data or speed limit data off the head unit if you don't have an active data connection to run your system and constantly update offline maps.

You may be able to make a hotspot out of your phone, and connect the head unit to it...but it is not "sticky" meaning you have ot start this connection on every startup...Yes, it is a money grab by OnStar/GM/ATT...the up side is you always have fresh map data.
