Update: Service Stabilitrak and Wild Braking
It's been nearly 2 months, and I wanted to let you know what has happened.
A very knowledgeable XLR Tech has gone through the electrical circuits, and, over the phone has worked with a GM Engineer to resolve this issue completely and correctly. We agreed I'd pick the car up on 7 Aug. He had driven the car close to 200 miles without an issue. I drove from Las Cruces to home in El Paso on that day (about 22 miles) Friday and determined to drive it as much as possible before my Wife returned home on Sunday evening. I had no re-occurence of the service stabilitrak message, or especially, of one of the front brakes momentarily locking involuntarily.
Had my Wife take it to her office Monday, no event(s). Then Tuesday she drove it to the office again (it's about 8 miles).
Several minutes after she left, she called. The service light came on again, but no brake lock. She was afraid to drive it and insisted I bring her one of the other cars. When I switched vehicles and drove it home, I had no issue.
The following day I drove about 3 blocks to an auto store for some wax product and got the service message. Returning to the house, just before I turned onto my street, the left front brake locked and released.
Now, the Dealership has requested a GM Engineer to come to their store and work with them on the car's issue. He is to arrive this week, and we will see what happens.
I am working with the Tech, who is also the Service Dept Foreman, on documenting what he did during the first period in the shop, and then what all occurs during this next period. Hopefully, we can get this fully documented and the realistic cause and repair requirement for a more permanent fix posted on the Corvette and XLR forums.
