Vehicle dash and headlights turn off while driving, engine stalls and dies, power steering becomes inoperative. Transmission pops out of gear and freewheels. Service stabilitrack light. Very dangerous situation for my wife and 5 kids when this happens on curvy backroads at night like just happened last night! this is also the same problem as our previous Chevy Tahoe so we knew the problem was likely related to poor quality battery cables that are degrading prematurely. This should not be happening on a 3-4 year old vehicle. After searching a GM web forum and finding other people complaining about the same issue, there was a reference to GM tsb 18-na-161 on this exact issue I am absolutely amazed that GM has not done a recall on this yet, as it is a major safety failure likely to cause a crash and potentially a fatality. I checked the tightness on the connections by hand, which were both very tight, then I reseated and torqued the battery terminal connection. I measured the resistance across the power jumper, lug to lug. This is GM part number 84494554, and I measured 0.3 ohms across this little section of wire at multiple points on the lugs. Trimming back the insulation and continuing the measure, the highest resistance appears to be coming from the wire to the lug connection at the fuse bus, and not the crimp connection at the battery terminal, and not the bolted connection to the bus. There were some strands broken at this connection. I made and added a temporary jumper of the same wire gage, and the resistance across the same measured points dropped to 0.0 ohms. Absolutely a major safety issue if the vehicle suddenly dies without warning. I can see this same issue happening once, I forgave GM once years ago, but with the same issue happening to two different vehicles 8 model years apart, the safety of my family is too important to buy GM product in the future.

I am trying to have GM reinstall the safety feature, lane departure warning. GM recently literally took away the haptic warning function recently by "updating" the software in the 2017 Suburban. On page 298 of the owner's manual it states that when the car drifts to the left or right, the lane departure feature will either beep or there will be a rumble in the seat on the left or right side depending on the drift. This is a safety feature I paid for and like very much. It is very useful to be subtlety reminded that the car is drifting to the right or left. I have contacted customer service twice to no avail. I have written mary T barra, CEO of GM, and have not even received a "we're working on it" reply from her. This is a pure and simple safety feature that GM has taken away from me, with no explanation or regrets. Please advise on the best way to resolve this issue.
