NHTSA Complaint #11709087 — 2025 CHEVROLET EQUINOX

OnStar Module malfunctioned, has been diagnosed and awaits identification of specific type of module to determine if one is available or if it is one that will be on back order. The safety of myself and my family was put at risk, along with others, when vehicle braking system randomly activated and slammed on the brakes despite clear highways all around, almost causing us to be rear-ended more than once. This has happened prior to 12/01 several times randomly but we assumed the sensor was sensitive and was picking up something we couldn't see, however this was not the case in this situation. The battery keeps going dead and needing jumped and there are numerous warning messages/lamps. Dealer service department confirmed OnStar module failure and need for replacement, has not yet reproduced braking issues. Vehicle is currently at dealership service department for inspection and was deemed unsafe to drive at this time. Dealer stated they had no loaner vehicles to supply and instructed us GM would reimburse up to $45 daily for rental at Enterprise, so a rental vehicle was obtained and placed on waiting list at two different dealerships for loaner vehicle. WiFi and Navigation System originally quit working, then car battery started dying and requires being jumped multiple times if not driven within 8 hours, Received alerts off and on of "Lane Change Alert System Off", "Service Parking Break", "Adaptive Cruise Control Temp Unavailable", "Service Power Steering", "Service Electronic Stability Control", "Service Transmission Now, Unable to shift soon", and cruise control/Lane assist etc quit working. We became stranded in another town and had to purchase a portable jumper. Dealer currently has no anticipated repair date.
