What owners wrote
My vehicle died unexpectedly in the middle of the road while backing out of my driveway with cars coming and going around me. It would not start up again nor could I put it in neutral to move it out of the way. I’ve learned my 2021 Suburban has a defective high pressure fuel modular. Also learned there is a parts shortage as well.
