Incident May 2, 2022

The motor started running bad and within seconds it stopped no other signs or problems

Incident Feb 28, 2025

At only 71,000 miles the 6L90 transmission had to be replaced in my Silverado because of slippage in fifth, sixth and heavy metal shaving showing in the pan. I have never plowed with this truck or abused the transmission. I've only towed up to 7,000 lbs which is well within specifications. As I continue to talk with other owners of the 6L90 and various mechanics, it has become evident that this particular transmission has a very high failure rate. Unfortunately the core to the failed transmission has already been returned, but what if something major internally failed that locked up the drivetrain and caused an accident? My mechanic John Portal has replaced several 6L90's with multiple types of failures. The only warning I received from the transmission was an engine light which only appeared after the transmission started to fail.

Incident Dec 9, 2020

Chevy Duramax trucks, 2011-2016 use a CP4 fuel pump that will eventually fail. The engine shuts off and there is a loss of steering and brakes. This is a major safety issue. I called Chevy GM 1800 222 1020 and was told, " we are aware of the problem, have no remedy, no recall has been issued yet, call back in a month". My daughter has a 2015 that failed when she was hauling expensive horses, the dealer put the same type defective pump back in the truck. Every diesel repair shop, dealer, and GM is aware of this defect. There is a class action law suit C/O JND Seattle WA. 1 866 848 0815 that may reimburse owners that have had a failure, assuming they are still alive. GM needs to recall, and replace these CP4 pumps with a CP3 or whatever they did to correct the issue in 2017 and later engines, prior to failure. Let ne know if I can provide any more information or assistance.

Incident Jan 6, 2023

My 2016 Chevy at a stop light started jerking and then just shut off and wouldn’t start again. I had to have it towed and was told at the repair shop that it was the CP4 fuel pump that went. Of course I had them do all the repairs and they found metal shavings all through out the fuel system. I was without my truck for weeks and had to pay ridiculous cost of almost $13,000. With how often this is happening this should all be reimbursed to me and GM needs to step up and take care of it along with NHTSA.

Incident May 28, 2023

The wipers stopped working during heavy rain in the middle of Highway. Can hear the motor running, but the wipers fail to operate. If I operate it by hand while the switch is on low or high, I can move the blades full cycles, but it does not operate on its own. I believe it is the wiper transmission at fault like many other Chevrolet models (Equinox, Impalas, etc). It was highly dangerous, as in the middle of highway I totally lost my awareness of surroundings. This is unacceptable and dangerous problem, and should be recalled if affected by significant number of owners.

I had to turn the vehicle off several times and restart it several times before the issue resolved.

Incident Sep 30, 2022

I was driving home from work on a busy road that had road construction and my truck without warning just died as if it ran out of fuel. I had it diagnosed and it’s the MP4 injection pump that went bad. Very common in this year it’s a minimum of$9500. To replace the entire fuel system. It could have caused me to have an accident. And GM is aware of the injection pumps going bad. The MP4 pumps are designed for vehicles in European countries not the USA. Ford and Dodge have class action lawsuits against them for this faulty system.

Incident May 20, 2019

I purchased 2016 Chevrolet 2500 HD from the dealership. The truck I bought had the CP4 high-pressure fuel injection pump, which comes standard in all GM-manufactured 2011-2016 6.6L Duramax diesel vehicles such as the Chevy Silverado and GMC Sierra, and it is incompatible with U.S. diesel fuel. The pump was originally designed for use in Europe, where the diesel fuel is "dirtier," or more lubricious, than that of the U.S. Because of the heightened pressure that the CP4 exerts in order to increase fuel efficiency, it causes the pump to disintegrate on itself, as the pump's internal metal parts rub against one another generating friction such that metal shavings wear off and are dispersed throughout the high-pressure fuel injection system. This process begins from the very first crank of the Duramax engine. Once these metal shards have sufficiently contaminated the high-pressure fuel injection system, the CP4 fuel pump will suddenly and catastrophically fail — oftentimes while the vehicle is in motion — and become unable to restart. I’m now looking at a $11,000 repair bill. GM knowingly sold a truck with defective parts.

Incident Sep 9, 2022

I’m getting a service trailer brake system notification( it’s has been showing up for awhile now). I’ve seen several times where this has come up with individuals that own the same year and makes. Why hasn’t Chevrolet address this situation yet. Any solution would be helpful.

Incident Jul 22, 2022

I was driving down the road, the truck began to shake and bounce real bad. I took to the dealership we purchased the vehicle from and they said $3500 for a new front end to replace all the parts. This truck has never been wrecked or hit anything. This vehicle has 85000 miles on it and its supposed to be a diesel farm truck. It appears the front end was made with parts and material that is not in compliance with industry standards. I was told by the dealership mechanic that the front end could collapse going down the road and injure someone when it collapses. This is on the front end of the truck, the entire front suspension is inadequately equipped with components to maintain the structural integrity of the suspension system.

Now a moderate dip will cause a left/right shudder in the steering wheel and no control of steering until it settles out. Had it aligned and dealer said all components were good. Out of warranty, dealer said the tab on problem would help for a period of time at $800, or a new steering box would be a longer but not permanent fix, at $2000 or so. Stated very common with this truck along with needing frequent realignments, all related to new electric steering system.
