Battery voltage low and required a jump to start. Advised battery had to much resistance. Drove to dealership. Upon pulling out on to highway without warning sudden engine loss and stalls. Steering column locked and shortly after the brakes locked up making it to where the vehicle could not be moved. This is a major safety issue and WILL lead to a fatality. My drivers side door exposed to oncoming traffic on a highway. 2 tow trucks, multiple technicians to coordinate keeping jumper cables on long enough to keep the brakes functioning to move the vehicle. Once the power was lost the vehicle seized. This happens on an actual interstate or railroad crossing YOU WILL HAVE FATALITIES!! This vehicle needs an immediate recall and pulled off the road! It took 6 hours to get this truck moved! This happens on the interstate or railroad crossing and sits for that duration due to everything locking up people will die as a result!

The vehicle experienced a catastrophic fuel system failure involving the high-pressure fuel pump and related fuel system components. While driving, the engine began stalling and lost power, making the vehicle unsafe to operate. The failed components were replaced during repairs; however, the repair records, photographs, and additional documentation are available for inspection upon request. The failure created a significant safety risk because the vehicle stalled unexpectedly while being driven, resulting in a sudden loss of power. This placed the occupants and surrounding motorists at risk by reducing the driver's ability to safely control the vehicle or move it out of traffic. The problem was confirmed by an independent repair facility, which documented extensive metallic contamination (metal shavings) throughout the fuel system. Photographs and videos taken during the inspections document metallic contamination within the fuel system. From our understanding, cp4 pump failure has been a common issue.

I'm reaching out for urgent help regarding my 2024 GMC AT4, which is currently at Newby Buick GMC in St. George, Utah, with a transmission failure that occurred on Saturday, [XXX]. While returning from a horse show in Ogden, Utah, the truck began to experience severe transmission issues near Santaquin, Utah, around 5:30 p.m. Just before reaching Santaquin, the truck jerked violently three times-so hard that I immediately checked the camera system inside my horse trailer to make sure one of my horses hadn't gone down. That's how intense the jolt was. I pulled into a gas station in Santaquin and called the dealership right away. At the time, I had three horses on board, it was nearly 100 degrees, and I was hauling a large living quarters horse trailer. The service manager was initially unavailable, but he returned my call shortly and advised me to continue driving to St. George at a steady speed if the truck could manage it. He also warned that it might go into limp mode, and in that case, I'd just be traveling very slowly. My husband was on standby in case he needed to meet me halfway, but I was hopeful that I could make it to at least Hurricane, Utah. I was able to access my GMC app on my phone at the time and confirmed to him that the transmission check light was on, and I was receiving a warning notification on the app indicating there was a transmission issue. I was able to limp the truck as far as Hurricane, where my husband met me. We unloaded the horses into stalls and took both trucks into St. George that night to drop the AT4 off at the dealership. On Monday morning, I contacted the dealership for an update and was informed that the issue was likely related to the transmission valve, and that the required part is on national back order-with an estimated delay of two months or more, but no confirmed ETA. This has been my first GMC diesel. I've always driven Dodge trucks. Over a year ago, I saw the new color GMC released and kept telling my husband how amazi INFORMATION REDACTED PURSUANT TO THE FREEDOM O

I was traveling on a busy roadway at 40 MPH when fuel filter warning light came on suddenly and vehicle lost all power - including the loss of power steering and power braking. Thankfully I had not yet entered the highway and was able to slow vehicle down but with great difficulty and not injure anyone around and that day was not towing a load. Vehicle would not restart. I had it towed to nearest dealership who then informed me that the "bosch cp4 fuel pump" had exploded sending metal shrapnel throughout the entire engines fuel system. The only fix was the entire replacement of the fuel system at a cost of over $11k. I had just purchased the truck 3 months prior. Upon hearing this, I see this has been a frequent safety problem affecting a whole line of 2011 - current gm, ford, dodge, and jeep diesel vehicles equipped with the cp4 pumps. There are numerous lawsuits underway for this failure including one of a major accident while towing (what these trucks are made for) because of loss of power steering and braking upon engine stall after fuel pump explosion. The gm technical service bulletin for reference is #16-na-102. In addition, the federal safety agency has received two manufacturer technical service bulletins on this very safety issue. This is very much a recall worthy safety issue. Losing engine power and loss to all power steering and power braking in these vehicles is beyond dangerous. In addition, when it is happening to vehicles designed to tow weights in excess of 30k pounds trailer load behind the affected vehicle the danger is amplified that much greater. Please issue a recall immediately. People's lives are very much at stake for gm's failure to remedy a known safety issue. Gm lists it as only a "hard start or no start". They do not recognize in writing the danger of full power loss at highway speeds which is most often how it presents itself.

My 2001 gmc sierra 3500 with a 8.1l v8 engine stalled while on the freeway. It would not restart until a "cool" down period. This problem surfaced as not being able to start the engine after it had run and then set for 30 - 60 minutes and would not start until several attempts were made to start it. This has been an ongoing problem for the last year and has progressed to the stall on the freeway. I was finally able to get an engine failure code from the vehicle listed as crankshaft position sensor failure. Upon doing some research I found the recall from gmc (06083 -- crankshaft position sensor engine stall) and called the dealer which informed me that my VIN was not covered under the recall. I then called gmc's customer service and explained that I'm having the exact problems listed on the exact vehicle with the exact engine listed. Also I have since found 3 other complaints with the federal safety agency of this exact same problem on other vehicles that were not covered. It is evident to me that this problem exists beyond the block of VIN's gmc recalled and should be extended to cover these other vehicles. Gmc does not seem to be interested in extending this recall and it should be looked into as a vehicle stalling on the freeway is an extremely dangerous situation that should be resolved.
