2022 GMC Sierra 2500

The Exhaust Pressure Differential Sensor Pipe (boost pipe) blew off while towing a heavy trailer uphill on a busy interstate. I had to cross 3 lanes of traffic to get as far as possible off the road. The truck was sent into limp mode and would barely crawl. Our lives were put at risk of being hit by the many tractor trailers traveling that highway, or another driver traveling at high speeds. The truck was eventually towed to the nearest GM dealer for service. The pipe was replaced, but the faulty one was not kept on hand. The repair was not covered by GM. The extended warranty covered the pipe repair only, with out of pocket still being over $400. There were no warning lights on the dash until after the pipe blew off and the truck was thrown into limp mode. This is a known problem with these diesel engines, for years, yet nothing has been done by GM to fix the problem. Owners are replacing with aftermarket parts because the factory parts won't hold up. This damaged the DPF and DEF system as a result. The replacement parts are listed in my owners manual under the 5 year/100000 mile powertrain warranty, yet the claim was denied by GM. There are forum after forum with these failures for the past 15 15 years or more, yet nothing has been done to fix the problem and owners are put at risk of injury or death. When the dealer replaced the part, it was disposed of so no inspection could be made by anyone else to determine if it was defective.

Filled tank with diesel and truck wouldn’t turn back on. We were next to a jiffy lube and they were able to run a scan and it said there was a broken fuel module. There’s only around 60,000 miles on it, it’s 4 years old, and left my son and I stranded.

My 2022 GMC Sierra 2500HD was previously repaired under GM safety recall N232426400 / NHTSA recall 24V060 for the power-unlatching tailgate switch, which can fail from water intrusion. The recall repair was completed and the recall now shows as closed. Recently, the same tailgate switch problem occurred again. The dealer diagnosed water intrusion/corrosion affecting the tailgate release switch circuit, including damage to the related wiring harness/connector. GMC customer assistance stated they could not assist because the recall is closed. I am reporting this as a possible failed or inadequate recall remedy. The same water-intrusion condition addressed by the recall appears to have recurred after the recall repair, and the vehicle now requires additional repair to the same tailgate release system. This raises concern that the recalled safety defect was not fully remedied and that other vehicles may experience repeat failures after the recall is marked complete.
