The vehicle had a sudden loss power shortly after i started the vehicle. When I pressed down the gas pedal, the vehicle turned off. It was only a 20 mph zoned residential neighborhood so I was able to safely coast to the side of the road. I dont think i could have safely gotten to the side of the road if it had been on any type of a multi lane road. There was no warning, no lights, no sounds that there was a problem. I had the truck towed to the local dealership as i was 120 miles from home. The mechanic at dealership said it was a faulty -??fuel pump power control module-?? and that they are failing a lot. Last I heard that the part was on nationwide back order. There was a recall for this very same problem over a year ago but my vehicle is not part of the recall. Yet the problems are still occurring with many similar vehicles (Tahoe / Yukon)

On a road trip out of state we stopped for gas. We got back on the road and few miles out the car suddenly slowed and gave a message on the screen something about acceleration. We pulled over and next the reverse didn-€™t work. We stayed overnight then next day the reverse still did not work. We were able to place in drive and continue on but we don-€™t have fully functioning reverse mode.
