The fuel pump has put metal shaving all through my fuel system and It is available for inspection if anyone is interested in taking a look at it. It made my truck die in the middle of the highway. It put me and a lot of others in danger! AutoNation Chevrolet seen and confirmed and said it was because the cp4 fuel pump isn-??t compatible with my truck and that a class action was just granted over this in 5 states. The Chevrolet dealership inspected the component. Only light that came on was change fuel filter and I got it changed just a day or two before it died on me.

While I was pulling my trailer up a grade on my 2014 Chevy Silverado 2500HD diesel truck, the fuel pump had catastrophic failure resulting in total loss of power. I had to unsafely maneuver to the shoulder of the 10 freeway west near Cabazon, CA and exit the truck near high speed traffic. I was lucky to make it to the shoulder without getting run over by the trucks in the slow lane. Had to wait hours for a tow and now have a roughly $10k repair bill. This is a known issue with the Bosch CP4 fuel pumps that Ford and GM refuse to address. Ram/Stellantis recalled their diesel trucks for 2019 and 2020 using this fuel pump. Dealer has confirmed total failure of the Bosch CP4 high pressure fuel pump as the reason for total loss of power. No warning signs whatsoever, just immediate loss of power while traveling 55 mph.

I have several dtc codes U029D U029E P0420 P220B on three occasions. These code are triggering a limited speed and possible power reduction. The dealer ship states that GMC protocol is to replace one sensor at a time and let the customer go so they can breakdown again. The part that is failing I am told is the diesel particulate filter, but GMC can not supply the dealerships with the high demand. This seems like a faulty design that may work during the warranty period, but shorty fails after. I did report exhaust smell in the truck while driving. I was given a report and a large repair bill only to breakdown in 126 miles.

I bought my 2014 Chevy K2500 durmax diesel 4X4 I bought it under the impression I was told it would get really good gas mileage and its horrible the salesman said the new requirements that GM done to the exhaust and fuel the gov. Required was to help on pollution and fuel mileage. This should be looked into the fuel economy is horrible.

While driving the vehicle the check engine light comes on, the stabilitrak light comes on and the vehicle shuts off. Within seconds the engine restarts. The most common occurrence is when traveling on bumpy roads. When this happens at freeway speeds, the same will happen, and the cruise control will disconnect, and cannot be reset until around 30 minutes. Again, the engine will die and immediately restart. This is happening much more frequently lately. The vehicle has approximately 95,000 miles on the odometer.

I own a 2014 Chevrolet Silverado 1500. While traveling T a a low rate of speed/under 40 mph, there is a sudden loss of power. The vehicle hesitates numerous times and stalls. The vehicle almost shuts off but recovers just before shutting off and the start of losing power the vehicle jumps and stops. Called dealer service department and was told there are no recalls for my vehicle. This problem started almost frome week one after purchase until this date of reporting.

Purchased a new 1500 in may of 2014 and a few months later noticed the engine has a random miss both while driving as well as at idle. Will experience a significant jerk and will also hesitate to pick up speed shortly after experiencing the jerk. I have reported this problem to Chevrolet on numerous occasions, but only have 4 invoices (from 11/20/14-8/26/15) with the complaint listed. Each time Chevrolet stated no problem found or present except for the most recent invoice dated Aug. 26, 2015 in which after Chevrolet service manager became involved because I complained about an unresolved issue, he did state that the problem was noticed by a "senior service technician" and since no code was present to diagnose or correct the problem, GM was contacted. Was told by the service manager that GM stated "they are aware of the concern but as yet have not formulated a repair." I am presently still experiencing the issue, but since GM has not "formulated a repair" for an issue that they are unsure of the cause and in which they feel "is not a safety issue" I am driving a vehicle that could stall at any given time. Be sure each complaint is documented via invoice number and make sure what you are told via phone and or in person is what is stated on the invoice.

2014 Silverado shakes at various speeds. Has been a problem since the date of purchase and have been told by the dealership that there was nothing they could do to fix it. There have been complaints of this happening on the vehicle dating back to Oct. 2013, GM has been aware that the vehicle shakes and that has not been a recall issued. Dealerships are still selling the truck knowing that there has been numerous problems reported.

Shifted truck into reverse while plowing my driveway, truck made a large snap sound in front end and wouldn't move - oil was dispersed all over the ground. In the end - front yoke broke, causing drive shaft to hit oil filter and busting it off. Truck was under warranty so no cost but this is dangerous. Had I been moving this could have caused a truck to flip end for end.

2014 Chevy Silverado consumer stated the vehicle was leaking oil

- Reading, PA, USA

Truck engine completely shut off while driving in normal traffic. Coasted to side of the road and restarted the truck. Check engine light was on solid. Took to a Chevrolet dealer who refused to work on it but told me the 3 codes showing related to the camshaft. Drove the truck home and it felt like it was misfiring as it was jerking around the entire time. Chevrolet had it towed to another dealer who said, again, there is nothing wrong. Told them this is a clear safety issue and the dealers are just clearing the codes because they do not want to take on the warranty work. Awaiting resolution from General Motors. They told me for now, I just need to drive it until it happens again.
