2025 equinox ev- OnStar Telematics module - no dates for backorder part is unacceptable
Unfortunately, my 2025 Yukon Denali keeps giving me nothing but problems.
My truck has been without an OnStar service for 20 days because of DEFECTIVE Telematics module and unfortunately the dealer can only provide the Backorder with no ETA for modules to become available.
This means no OnStar, Super Cruise, Wi-Fi, Entertainment System and a BIG Check Engine light !!!
GMC needs to step up and provide the parts and service to the customers, this is a not a dealer problem, this is a known quality repetitive issue that must be resolved Immediately.
We are in the same position as you. Have you received the module yet? Ours has been in the shop about three weeks, with no ETA.
Have mine in shop currently for same issue. No connection to app, no navigation, speed limit on dash not working , and no onstar connection. Is this considered a safety issue and are there other issue that may occur with this problem ?
This module is a defect and definitely a SAFETY issue. The telematics module has the potential of draining the battery completely which can cause the car to shut off MID DRIVE. I know because it happened to me TWICE.
I have reported the safety issue to the NHTSA

I have also reported this to the Federal Trade Commission because it is fraudulent practice to advise consumers that these vehicles are still safe to drive.

Many of us have contacted GM DIRECTLY to file a complaint at
We have also contacted a Class Action Lawyer based out of Philadelphia that has gone up against GM before. Speak with Michelle
UPDATE: GM called me back to discuss this issue twice and they are trying to contact the dealership for payment assistance options.
