While driving in excess of 55 mph on I 95, my 2011 Chevrolet Silverado 2500 stalled without warning while I was in the far left passing lane. No power steering or power brakes made it extremely difficult to control while moving through 4 lanes of traffic to get to the shoulder. I was unable to restart the vehicle and had to have it towed to a garage. I was informed the cp4 fuel injection pump had failed and repairs will be in excess of $8,000 because the entire fuel delivery system was contaminated and needs to be replaced.
An article in trailer life (may, 2019) identified that the bosch cp4. 2 high-pressure fuel-injection pump is subject to catastrophic failure. It points out this is a common failure, a design issue and will cost many $1000's to repair. It has been called a "fatal flaw". It should be replaced with a unit that is reliable by the manufacturer if this is a common problem. Michigan s&s motorsport states this is a known problem and is common to 2011 to 2016 duramax diesel silverados using the bosch cp4. 2 fuel-injection pump.
