Default ONSTAR Antenna Will Not Stick!

Got my 2010 in March of last year, and last summer the Onstar antenna kept falling off of the windshield because of the heat inside the car. It took the dealer 3 tries before he could find a glue that worked. But last week, the same thing happened again. If I am parked outside, I always leave the windows down about 3 inches. One would think that Chevy could find a better way to install the antenna. Anyone else having this problem, and, if so, what is the solution?

Could be good glue, but bad prep job by the dealer. Also, there are some strong double sided tape options that should work if applied correctly.

Could ask a windshield/glass shop, they would probably know best.

Bulletin PI0099A addresses this.

The service advisor at the local dealership initially told me they had to order a replacement bracket and they'd get back to me in 2-3 days. It's two weeks later and I finally called the dealer's parts department who told me he had to talk to GM in order to get the proper part. He said one option is to replace the windshield, which I confirmed from another message on this forum and a Google search.

You might stop by any auto glass repair place and see what they do since they have to deal with this.

You aren't alone...the one in my 2010 GS comes loose nearly every time I drive it to work or leave it out in the sun this summer. Never had the problem on my 08.

You need a glue that sticks to glass AND plastic. Could be the glue is not sticking to the OnStar, not that the glue isn't sticking to the windshield.

I was looking at a new 2010 coupe this summer and it was hanging off the windshield on the dealers lot. Obviously there must be a problem with the glue they are using.

During the last 15 years of Vette ownership, I have read many problems the Vettes and their owners experience. I have only had one very minor issue (rocking seat on my '02 Z06) but I do have this same problem.

I was going to take it to the dealer to have them fix it. But have not had the time to. I am wondering whether or not some wide black velcro would work? You can buy the velcro at Home Depot or Lowes.

When it's cooler I have no problem but when it warms up I find the Onstar hanging by it's wire. There is also no clip behind there just some gummy glue. I'll probably go with double sided tape.

It slides to the right, then lifts off the "fingers".
Most people report that a hard push will move it, mine required a thick dowel and several whacks with a hammer (on a warm day!).

Mine was replaced by a Valentine 1 detector, which is fairly well hidden by the black area on the windshield.

Everything except Onstar continues to work normally, I did not pull any fuses.

Default Same problem, different solution

Exact same problem with GS 2010, 13,000 miles. Chevy dealer said that the antenna needed a special adhesive tape that is not part stock for them and they authorized a windshield replacement. The new windshield made clicking and popping noises while driving. Took it back and will pick it up today. Also, I am seeing the black rubbery plastic(?) vertical trim pieces, that the dealer calls trim pillars, on both sides of the windshield, are starting to stick up at the top edge and catch my cleaning and drying rags when I clean the car. They tell me that these are not removed during windshield replacement but they seem to be now sticking up more than ever at the top end. They also told me that these pillars are fastened in place with five rivets - not sure what they meant by that. It's very irritating to see trim popping out on a car with this price tag. Anyone else experience this? I'm wondering if I can use a heat gun to lay them back down and ice to set it in place. I really don't want to disassemble anything on this car if not needed, especially trim pieces.

For me, it's a mystery. Mine fell off a half-dozen times when the car was new, but for the last two years it has stayed put.

Default Black Box

I tried a strip of wide Velcro and it seems to be holding for now.
