CP4 injection pump failure while driving nearly causing vehicle collision.
The CP4 pump failed while driving causing vehicle to stall. Upon failure, lost power to steering. Luckily we were on an access road for a rest area and not yet on the interstate. This resulted in a 14.5 thousand repair. No prior warning to pump failure. GM has recently settled a class action related to this pumps failure and has never recalled trucks with this pump to avoid failure.
My vehicles High Pressure Fuel Pump failed causing the vehicle to shutoff while driving. In addition, due to the engine shutting down while driving, the power steering quit working causing me to not be able to steer the vehicle. Thank you
My 2016 GMC Sierra 2500 with a 6.6-liter Duramax diesel V8 engine suffered a complete engine shutdownâan issue that is both hazardous and expensive to repair. Fortunately, mine failed in a parking lot. No warning lights or symptoms were present. Failure is instantaneous and can occur any time rendering the vehicle inoperable on high-speed highways, Intersections, etc. Failure always leaves vehicle occupants stranded, creating an unsafe and dangerous situation. My vehicle was towed to a GMC dealer. Repair costs could be as high as $15,000. The 6.6-liter Duramax diesel V8 engine is equipped with a Bosch âCP4â high-pressure fuel pump. These pumps are unreasonably fragile and prone to catastrophic failure causing instant contamination of the entire fuel system with metal shavings. General Motors has agreed to pay $35 million to settle with owners following a class action lawsuit that accused the company of installing defective Bosch CP4 high-pressure fuel pumps in certain Chevro

Motor stopped dead while driving on a local Interstate Hwy. Was able to negotiate the truck out of traffic without crashing. Not an easy thing to do in speeding rush hour traffic. Had the truck towed to a reputable repair shop and discovered the CP4 fuel pump had failed and shattered throughout the fuel system. Repairs in the amount of $13,520.30 incurred to get the truck back in service. The attached invoice includes $167.87 for other maintenance not related to the CP4 fuel pump repair. This is a known problem and safely hazard. A class action suit settlement is related to the CP4 fuel pump against multiple truck manufacturers. # [XXX] and can be found at [XXX] . Minnesota is not included in the class action and GM will not address my complaint. Why has this KNOWN safety issue not resulted in a recall?

2016 GMC SIERRA SHARK FIN ANTENNA GETS WATER UNDER AND DESTROYS ONSTAR, NAVIGATION, AND COMPASS OPERATION. THIS IS RECALLED IN 2015 BUT DOES NOT INCLUDE 2016 THAT HAVE THE EXACT SAME PROBLEM.
Vehicle is a Duramax Diesel engine with a CP4 fuel pump. The pump went out and the entire line/system has to be replaced. While driving the vehicle it lurched, made a noise then went to reduced power mode and shut off. Luckily we had just pulled off from a stop sign, if that happened and the speed of 55 it could of been far worse. Then engine would not restart and had to have vehicle towed.

I remote started my truck yesterday morning to get it warmed up before loading my family. They all then got into the truck, my 5 year old and 8 year old in the back seat in booster seats. I threw in some more bags into the back of the truck and started to climb into the truck. As I did that my kids were starting to get nervous and my wife was pointing and stating that the rear window slider was smoking. I put the key into the ignition and turned the key on. Upon doing that the smoke stopped but a few seconds later there was a loud bang, similar to a gun shot, and the rear passenger side window shattered. My 8 year old had glass hit her and my 5 year old was hysterical. Needless to say, the 5 hour drive home was not much fun for anyone after that occured.

While Pulling 35' 5th Wheel down freeway, a message appeared in instrument panel telling me the fuel filter was at 0 percent and was going into low power mode. There happend to be an offramp there that I was able to get off the freeway. While making the turn on the offramp the truck died. I pulled over as far as i could whie coasting with no power steering or brakes, leaving truck & trailer partially blocking the offramp. Unable to start the vehicle, I Immediatly contacted Onstar and they dispatched the CHP & tow truck. When CHP arrived he asked when tow truck would be there. Without being able to confirm exactly, and due to safety concerns because of blocking the offramp, he called his own tow truck (Rons Towing) and forced me to move vehicle to safe location. The issue ended up being the injector fuel pump (CP4) that GM was well aware of going out and sending metal fragments throughout the fuel system. I've been told the pump was made in China and not to GM standards. The vehic
