I have a 2012 Equinox with 68,000 miles. It's been a great vehicle until June. The service Stabilitrak warning light came on, the ECO on flashes on and off, the speedometer, tachometer, and temperature gauge jump back and forth, and it has been shifting very rough. Cruise control will intermittently shut off. The first time at the dealer they could not replicate the problem. As soon as I pulled out of the dealership, it did it again and I turned around leaving it running when I dropped it off. They replaced a wire that they said had become pinched and warn through creating a short. Within a few weeks, it was at it again. This time they said it was a loose ground wire. Again, within a week it was doing it again. I dropped it off Thursday night for an appointment first thing Friday morning. Today is Monday, I called and left two messages. I still have not heard back. A quick internet search leading me here to this forum, shows this is a pretty widespread problem but not getting any answers.
