Yay, a new quirk! :-/
I don't really know how to describe this. About a week ago, I discovered that when I press my brakes kind of hard (not slamming on them, but like if I'm going 55mph and need to stop at a red light) the brakes kind of... slip.
I'll try to describe it the best that I can:
1. It feels like the brakes just go from being pressed to not being pressed at all for about 1 second, then all of a sudden they kick in at the same pressure as before. So for a brief second, you feel the car jump forward.
2. I've noticed that it happens when the "Generate" bar is pretty far to the left. When it jumps, the Generate bar jumps straight up for a second, then rotates left quickly back to where it was.
3. It doesn't seem to matter whether I'm in Stealth or Sport mode, or whether I'm in Hill mode.
4. I get no warnings from the infotainment system when this happens.
A few other potentially pertinent details:
1. I replaced the tires about 2 months ago, back to original Goodyear F1 Supercars. The local GM dealership replaced the tires. I doubt that it's related since everything was fine for 6-7 weeks, but still.
2. Back in September I think that lightning ran in on the charger, so it's running entirely on gas now. From an earlier thread, I believe the #5 contact is bad, but I haven't had the time or money to haul it to Florida or Philly and get it fixed.
But, it's worth pointing out that it WILL charge if I go down a significant hill, just not when it's plugged in to a 110 (I haven't tested a 220). The CEL stays on either way, though.
3. I thought the problem might be with the electronic stability control, but I can't get it to turn off so I have no way of testing it.
3. The car has around 17,000 miles on it, 8,000 of which are mine in the last year and a half. The weather here is cold but not freezing (around 40 degrees), and whether it's wet or dry doesn't seem to make a difference.
Any thoughts?
