NHTSA Complaint #11631997 — 2024 CHEVROLET EQUINOX EV

I bought a new Chevy Equinox EV on 12/13/24. The day I bought the car, I found that while driving home on interstates and other roads listed by GM as mapped for Supercruise, the system will work for a few minutes, then cut out. There is no warning in advance of this shutdown. When all this happens the car immediately brakes in the middle of traffic and loses steering control, red lights go off, and the driver must quickly assume control to prevent a crash. After it happens, the car pops up a message that the ACC is also unavailable. Then another message that Forward Collision Detection is also unavailable, at which point the whole Supercruise system shuts down until the car is turned off and restarted, and then the whole cycle is repeated. This even happened once in the middle of an automated lane change. It's extremely dangerous. I brought in to the dealer service the following Monday, 12/16/24. The dealer service dept. confirmed the problem and contacted GM, which responded that they were aware of the problem and had engineers working on it. They would not provide any timeline for when a fix would be available, but looking online, this problem has continued for many months with no solution. It apparently does not affect all cars, but there are plenty of reports online of cars that it does affect.
