class action lawsuit OnStar module backorder

I bought my 2025 Equinox in November. I started having issues with Onstar in March/April. I called Onstar and they said it had to be escalated to a manager and the manager would call me back in 5-8 days. No one ever called. It was a minor inconvenience, so I decided I’d have the service department address it when I was in for an oil change. I took it in for an oil change last week and was told (surprise) the telematic module is going out and needs replaced. They’ve ordered a new one but (surprise again) it’s on back order. The mechanic messed with it and said it was working but eventually will go out. Last weekend the Onstar button started blinking green constantly. Now, apparently, the Onstar continues to blink when the car is off. I went out this morning to take my son to catch the bus for a band outing, and my car was dead. The Onstar light was still flashing, but nothing else. It took several attempts to get it to unlock and then nothing. No dashboard lights, radio, absolutely nothing except the flashing green light. The green light quit flashing an hour later. We got it on the battery charger, and as soon as it was charged enough, the green light started flashing again. The minor inconvenience has become a serious issue. I cannot go without my car for months waiting on a new module.
