So someone else should have got in front of her car and impeded her speed? Be my guest, maybe you could have got a 2 for 1 special in funeral services. Hall monitor Security guard Citizen speed watcher Bus monitor Tattle tale peas-ina-pod Puleeze I don't have room in my life for such self righteousness.

If someone is behind you and wants to go faster, my opinion is it is rude to impede their desire period. Doesn't matter if its legal or not. I have no desire to enforce the law on others. Besides there is no reason not to try to make it easier for them to get around you. The more assertive or aggressive they are the more you should try to accommodate them. They will only get more frustrated and engage in riskier behavior that would ultimately put yourself at risk. Pull over, move over and let them go, everyone is happy. You want to hold traffic up behind you, fine - but if you die getting tangled up in a crash with someone, doesn't matter if you were going the speed limit or not you're still dead and I doubt there will be one word at your funeral about how righteous you were on the road.

2wd or 4wd? If it is 4wd is engaged? While turning or going straight? Does it have RPO code G80?

What? Haven't heard of anything like that.

I was thinking along the same lines, but not familiar enough to know how a failure in that component would result in the brakes applying themselves. I lean more towards the booster not sealing up like it should (maybe contaminated by a failed vacuum pump). If you pull the vacuum line off the booster and the brakes release at least we're in the right ball park. The vacuum pump to my knowledge is always running, I don't recall ever seeing a clutch on it, seems to me it is either creating vacuum or not - it SHOULD be creating vacuum at all times (the problem would be present at all times too). I suppose one could try to pop the belt off the vacuum pump to rule it out of the equation.

I've lost maybe .5 - 1.5 mpg since 'flipping the pill' in mine, plus the transmission temperatures still get just as high as it did before, just takes a bit longer to get there.

Is the ABS pump active/running when this happens? Could the rear brakes be engaged too but masked by the front brakes? Engine vacuum leaking to the atmosphere side of the booster, would cause the brakes to engage without pedal input, not sure if that is possible though. Open the bleeder valves when they are locked up to relieve pressure. Pull the ABS fuse to rule out any ABS issues causing it. Doesn't sound like a problem with the brakes themselves at least past the ABS pump and valve body.

"Left me stranded in Canada for two weeks. We ended up trailering it home." One wheel or both lock up? Do they stay locked up? When/how do they unlock? 2wd or 4wd?

Probably a leaking shock bag, or air line. There is no side to side leveling, one ride height sensor controls both bags, one compressor inflates both bags.

My previous truck had an issue where the driver side wouldn't get as cold as the passenger side. Took out the blend drivers blend door actuator, cleaned the contacts and greased the internals and that took care of it. Sounds like you are probably not dealing with a mechanical issue either. Confirm the compressor is engaging, maybe a temperature sensor is faulty telling the computer it is too cold to run the A/C.

IIRC its for a backup light. Not typically used on the seven pin connector.

The logic is sound, but why would anyone take a chance at a repeat bad product experience, that'd be just stupid.

Wrong quote...

Had the same issue on a 2009 GMC Acadia, is was a small solenoid/valve/sensor like described above to EVAP Purge... I don't remember but it was a pretty common and easy job on that car. I suspect it would be similar for a truck.
