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.

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!

I started the car. Backed out of my driveway. Put into drive. The car stalled I shifted to park tried to restart. It wouldn’t. At that point I tried to put car into neutral I couldn’t. There is no way to shift this car into neutral. ( I checked with service department at gmdealer). This alone is dangerous the car cannot be moved. Anyway the car was towed to a dealer who fixed it. It was th fuel pump power module. The dealer and tow truck driver both told me this happens at least 5 times a week. There is no recall on this. My biggest concern is I could be on any road going high speeds and this part can fail. This is a death trap. There was no warning lights or messages to be found. PLEASE TAKE THIS MATTER SERIOUSLY SOMEONE IS GONNA DIE.

Park Assist was not installed during production with retrofit to be done. Vehicle was manufactured in June 2022. Still no retrofit. Safety issue!!

Purchased new in March 2023 -Repair Safety Restraint System failed (alert signal) failed late June 2023. Inspected at the Dealer/mechanic on July 11 2023, and it was determined the Safety Restraint System panel was defective. Part ordered late June early July 2023 (estimate). Part was backordered and not available for installation August 31 2023. Service department failed to notify me that the part was in. I had to call them. Appointment was set for Replacement part to be installed on September 6 2023. In the meantime a new alert appeared (Check engine light). I notified the service department of the new issue (check engine ) and the need for them to inspect that. The vehicle was due for an oil change and rotation as well. Service department determined that the engine failure resulting in the (check engine light) was due to a defective fuel pump/injection system. Part ordered and an appointment was set. Replacement part was installed on September 12 2023. Literally three days later, after the fuel pump/injection was replaced, another alert appeared (check engine light). September 15, 2023. This particular vehicle has major issues and I am contacting the dealer for a complete buy back and/or replacement vehicle. My safety and the safety of my passengers was at risk from the first minute the restraint system failure signaled. The part was backordered for a long while. I had no other form of transportation. The dealership did not offer a loaner vehicle or to pay for a rental car, nothing. In fact they did not seem concerned at all. Not concerned enough for the service department to place follow up phone calls to me with status updates over the many weeks I waited for the part to arrive. The car obviously has electrical and fuel injection issues straight from the manufacturing floor (which according to reports Buick is aware of). Ref. Edmunds and NHTSA reports. There are a host of reasons why my safety was at risk during the few mo of ownership.
