class action lawsuit OnStar module backorder

This is a clear product defect. My Yukong XL and Suburban both have the same issue. I've also been looking at Carfax for used cars online and found that many had their telecommunicate modules replaced free of charge through a claim settlement program called the Friend Program. I recommend that all owners of vehicles for which GMC has paid for replacements, whether new or used, unite and demand a free replacement or sue GMC.

I bought a used 2023 Buick Envision Essence on 3/30/25 (from a Buick dealer). It was a previous rental/loaner and had over 49k miles so no warranty and I did not purchase a warranty. 1-2 weeks after purchase the check engine light (CEL) came on. Short version is it was diagnosed on 7/15/25...need Telematic module replaced - $1684.16 plus tax. I dropped the car off on Friday 8/15/25 for the fix. Interesting thing is part is not on back order for me... ETA for part to get to dealer is Friday 8/22/25. I'm in Los Angeles. Apparently California gets first dibs on parts. I feel bad for everyone here waiting for months! This doesn't make sense. 

My suburban and Yukon are same. GMC customer support enthusiastically called me, and the dealership enthusiastically helped me file a claim with GMC. However, GMC denied my claim to replace telecom module . I recently reviewed numerous Chevrolet and GMC Carfax records and found that most vehicles had their communication modules replaced free of charge through a friend program. This is a clear product defect, yet GMC not only failed to disclose this information, but is charging some owners for it. If GMC charges any owner whose communication module is damaged, I recommend that they obtain a lawyer to represent them and sue GMC for compensation.

Count me in. 2025 Suburban Z71. Things were fine during onstar trial period. Then plan selected no wifi/hotspot since. Escalated onstar case multiple times no luck. Dealership visit today (day loss of pay because this can only be done weekdays) no luck. Dealer tech says everything looks fine no error codes. I asked about the module issues i learned about here and he says it’s on back order. Im ashamed to say i went from Toyota to GM!!! Our modules are in back order and so should these vehicle payments! 

There needs to be a lawsuit filed. It’s become a time consuming financial burden and a safety issue. If anyone has started the process, or has knowledge of any?  I am not sure how to proceed. The module is on back order but they want me to come get the car and continue to use it (pay for it) without the safety features, functionality or ability to fully control the battery? We live in Florida. The screen gets so hot you cannot touch it, it cannot even display the correct time. This is a MAJOR SAFETY issue. Why isn’t anything being done?

I have a 2022 Tahoe LT. It just hit 42K and the Onstar Module is out. Just our of Factory Warranty.  It took me 4 days to have a technician look at it knowing it was the module so my SUV was stuck at a dealership and they finally confirmed after 4 days it was the module and is on backorder with no visibly of availability.  This is a really bad customer experience plus I am paying for a Onstar service that I cannot access.  There needs to be some transparency and accountability 

After weeks of diagnostics dealer found the culprit!! Yes you guessed it right TELEMATIC MODULE NOT COMMUNICATING!!! Oh and guess what, yep you got it again, IT'S ON BACK ORDER!!!!

Tawan Bruce-2025 Terrain onstar module needs to be replaced,  car was not drivable and needed to be towed. Currently still in the shop.  Almost 30 days now. 

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. 

Has anyone thought about taking this to the MEDIA? News outlets? Wouldn’t this be a great story for prime time? Let me know if anyone has connections. I’m camera friendly.
