The OnStar Telematics Module has malfunctioned and is causing SAFETY FEATURES to malfunction. It is causing the following to occur to the vehicle: 1. The faulty module is causing the car to shut OFF UNEXPECTEDLY MID DRIVE. Losing control of the vehicle instantly. No steering, no gas, no brake, no gear change. THIS can cause a CATASTROPHIC ACCIDENT at higher speeds on the highways. The battery is completely drained when technicians inspect it but the alternator is working properly. 2. Causes the vehicle’s safety features to malfunction and give alerts such as “Service Driver Assist”, “Lane Departure Unavailable”, “Forward Collision Assist Unavailable”, “Steering Control Unavailable Soon”. 3. Causes GPS, WiFi, and location system to fail. 4. OnStar safety button do not work 5. Causes the engine light to go on and off and causes the cars idling to run erratically. 6. The module causes NEW batteries to drain quickly, less than a year after purchase. I have had the car shut off on me twice MID DRIVE, I was lucky to be in areas of less concern and harm. I’ve had to purchase two batteries since the module malfunctioned. Less than a year apart. The dealership confirmed it was the Telematics Module January 2025. They have confirmed the part is on backorder and not covered under warranty. NO INDICATORS were given when the car shut off BOTH times that I may have noticed or heard.

The contact owned a 2022 Buick Envision. The contact stated that while driving at approximately 15 MPH, another vehicle failed to yield and collided with the contact’s vehicle. The contact stated that all of the air bags deployed. The contact stated that due to the steering air bag deploying, the emblem on the steering wheel column caused a severe arm injury. The contact was transported to a local emergency room and sustained severe burns on the forearm and wrist, as well as whiplash. A Police report was filed. The vehicle was towed and destroyed. The dealer was contacted. and referred the contact to the manufacturer for further assistance. The vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure, and a case was opened. The failure mileage was approximately 30,000.

I bought a used 2023 Buick Envision with 49k miles on it. It was not covered under warranty due to mileage. A couple of weeks after purchase the CEL came on. It was originally diagnosed as a bad battery. It was later diagnosed as a failed Telematics Module. I had the module replaced on 8/23/25 so it is not available for inspection unless the dealer has it. After reading many complaints for the same problem on many different GM cars I suspect the bad battery had been drained by the failing Telematics module. Although it did not happen to me directly others have reported the car dying in the middle of the road because the battery died. The car has only been inspected by two dealerships since my purchase. I am reporting this because there are so many others facing this problem. I live in Los Angeles and my dealership was able to get the part and replace it. So many others are not even able to get the part. Their lives are being negatively impacted. I hope you can gather enough complaints and force GM to recall these modules or come up with a solution. This is dangerous and extremely frustrating for many consumers. Thank you for your time. PS - I can provide the invoice for the module replacement if you need it.

I purchased my vehicle in 2020. In 2022 I experienced an issue where my car stopped in the middle of the road without warning. Despite several attempts to try and move the vehicle off of the road the police were notified and my vehicle was towed. The vehicle gave an error code that conditions not met for driving. One office tried to put the vehicle in neutral but the wheels locked and the shifter was locked as well. The battery has been replaced 3 different times since I have owned the vehicle. A mechanic friend of mine (who is a trainer for GMC) hooked his computer up to it and found no issues. He did find a loose wire which he the reconnected. I was able to drive my car for 6 months before the same thing happened, same situation the vehicle just stopped in the middle of the road only this time I couldn't turn the vehicle off, we had to manually disconnect the battery and again the police came out due to traffic hold up. My car was towed twice afterwards as I could get the car running for a few minutes before another error. To date my car has been sitting in my driveway since March of this year, this time it won't hold a charge and will not even start. Im not sure if this is an engine or an electrical issue. I did call 2 Buick dealerships that told me that it would take about 5 hours to diagnose the issue where I would be charged per hour at the mechanic hourly rate. At this point I think my vehicle needs to be recalled, even if I could get it repaired I dont feel safe driving it. Thankfully it stopped on a minor freeway and no major incidents occurred.

Telematics module drained my battery mid drive. Car shut off on highway. Module malfunctioned and caused safety features to malfunction. After communication with Dealership, OnStar, ultimately GM refuses to issue a recall on the module. This is a NATIONWIDE issue with GM Telematics Module. Warranty will not cover the module on any of these vehicles. Someone is going to sustain serious bodily injury or maybe even die eventually if this issue isn’t resolved. Dealerships are telling drivers it is ok to drive like this. My car shut off on me twice. I had to buy two new batteries because the module continues to suck the life out of them. Serious safety issue not only to self but unsuspecting drivers because there is NO WARNING! Please help the millions of people nationwide who are having issues with their GM vehicles that have malfunctioning Telematics modules before someone gets hurt or dies!

Wednesday August 6th 2025, I was coming home from work, the low engine compression and engine light came on the car was shaking and I lost power on a busy road, I had to pull it off the road quickly before I lost all power. I stayed there for a few minutes, then turned the car back on to retreat to a safer spot, I then waited for my husband to bail me out, we checked the oil on the dipstick, there was minimal oil on it. We added 1 quart of oil, then the lights went off, all seemed fine. August 23rd 2025, I was driving my car and the same thing happened car lit up with low engine compression and engine light came on car was shaking, I shit the car off. we added 1quart of oil. But the engine light stayed on after about 30 min. I shut the car off. The engine light went off after I shut the car off.
