If you are the current owner of a GM truck, you might have already heard the news that certain GMs have been connected to a defective fuel pump. Some consumers are considering their rights to file a defective fuel pump lawsuit. To identify whether or not you might have grounds to initiate a defective fuel pump lawsuit, you should first check whether or not your vehicle is affected by this issue.
If your truck hasn’t yet had a failure because of this possible issue, you might need to be on the lookout for potential problems. According to Pep Boys, fuel pressure gauge malfunctions,sputtering in the engine as your car gets closer to high speeds, and rising temperature are all problems linked to fuel pumps. All of these signs should be taken seriously.
Has a Lawsuit Already Been Filed?
According to a Reuters Report, one GM class action lawsuit alleges that GMC Sierra 2500HD and 3500HD Diesel trucks and Chevy Silverado 2500HD and 3500HD trucks were equipped with defective fuel pumps that are not compatible with diesel fuels sold in the United States.
Texas and California owners of the diesel trucks in these models manufactured between 2011 and 2016 might have to pay thousands of dollars in repair costs to fix these vehicles.
What’s Wrong with These GM Fuel Pumps?
The defective fuel pump lawsuit was brought by two plaintiffs who argued that the Bosch CP4 fuel pumps inside these cars were created to save money. The underlying argument is that the pumps use a reduced amount of fuel because of higher fuel pressures with reduced volume. However, U.S. diesel fuel, according to the lawsuit, doesn’t have enough lubrication to stop the CP4 pumps from failing.
Hot Cars reports that the fuel pump problem started when GM tried to capitalize on an increasing demand for pick-up trucks that ran on diesel.
Car Complaints says that GM advertised that the vehicles have high power and low fuel bills, in order to make them attractive to prospective customers. Allegedly, the company advertises that the vehicles will run for between 500,000 and 800,000 miles. However, customers argue that this was not the case.Â
Reportedly, GM worked with Bosch, a German auto parts supplier to create high-pressure fuel injection pumps for their trucks. The Detroit News explains that that the pumps are designed to work with European diesel, which is thicker than American diesel. However, because American diesel is thinner, it provides less lubrication than European diesel.
This can then reportedly cause air pockets to from inside the fuel injection pump. When there are air pockets in the pump, as opposed to having the pump coated in diesel, metal can reportedly rub on metal, which generates metal shavings and causes operational problems, says The Detroit News.
Car Complaints says that the problems associated with this incompatibility between the pump and American diesel can be costly. Some owners say that repairs can cost up to $20,000, especially as the pumps may have to be repacked.
Additionally, some customers say that the pumps can fail even in just the first mile of driving, meaning that drivers may face a serious cost almost immediately. Some customers report that the engine failure is sudden and catastrophic, and others describe that the pump explodes from the problem.
Did General Motors Know About the Fuel Pump Problem?
The class action lawsuit argues that General Motors was aware of the diesel fuel pump problems and knew that this would make the vehicles much less valuable than they otherwise would be without the high pressure CP4 pumps.
The lawsuit also argues that GMC and Chevy trucks have other problems because there are inaccurate lift pumps that could be installed to help supply fuel to the pumps.
This leads to unnecessary wear and tear and overall damage to the pumps. GM is accused in this defective fuel pump lawsuit of failing to install a filter between the injectors and the pump to stop metal shavings from going through the fuel systems of the truck. This can lead to significant problems for owners and massive repair costs.
What Does Replacing a Fuel Pump Cost?
Replacing a fuel pump could go as high as $10,000 in repair costs for the consumer, according to those consumers who filed suit against GM. The plaintiffs who have initiated the lawsuit allege that they should have been told about the damage potential when purchasing the vehicle and some of them say they would not have made the purchase decision if they knew about the possibility of GM fuel pump failure.

I have a 2016 Sierra 3500 HD Denali and the engine blew at approx 138000 miles
I have the 2013 2500HD Duramax. I am at 208,000 miles and would like in on this settlement so I can get the CP3 pump installed. I run fuel additive to lubricate my CP4 pump to prevent failure, but that cost is continuing to climb.
I have a 2011 Chevy Silverado 3500HD and the fuel pump broke on the way home from a 2500 mile trip. I was towing a car trailer home from Utah to California with a 1967 Camaro that I just purchased when my fuel pump got clogged up with metal shavings and ruined the entire fuel system from the tank all the way to the injectors and the fuel return line back to the tank! It left my wife and myself stranded in Reno with no place to go. We had to pay for a tow company to tow my truck with the trailer and 67 Camaro on it to the closest Chevy Dealer in Reno and spend the night in the broken down truck in front of the service shop, then wait until morning to see if they can help me so that we could get home. I The following morning I unhooked my trailer and the pulled my truck into the diesel mechanics bay and he took a couple hours to diagnose the problem. Turns out that the fuel pump was defective and had to be replaced, they told me that it would cost anywhere from $7500 to $10000 to fix it, the only problem was that I would have to leave the truck there and they would have to order the parts and couldn’t give me a completion date. The dealer did say that they would take the truck as it sat for a trade in for a new truck! I told them no thank you and made arrangements to have the truck towed back home to California a little closer to home. I eventually had the truck brought to a local Chevy Dealer and had them fix the truck. I was able to reach out to GM and with the help of the dealers manager they helped out with the cost due to me being a loyal GM customer that has bought many new vehicles from GM. The total bill from the dealer to have the truck fixed was $11000! Luckily with GM’s help I had to pay $4000 ! When I later found out that GM knew of the faulty fuel pump, GM told me that it was not covered under any warranty and that they would not reimburse me for the $4000 that I had to pay! I feel that I shouldn’t have to pay for any part of the repair costs to my truck! I WOULD LIKE TO JOIN ANY CLASS ACTION SUIT AGAINST GM TO AT LEAST GET SOME OF MY MONEY BACK!
They screwed us loyal customers on the 6.5 electronic controlled detroit diesels they sold till late 99 ! My family owns a chevy dealership and I’ll never buy another chevy as long as I’m alive ! We also own a dodge dealership all I’m running from here on is a cummings ! A million mile monster they never let you down and will pull city hall off its foundation ! I still have my 99 6.5 waiting on chevy to do the right thing and buy it back ! It will prob become a pile of rust ..They lied and said they would fix them and never did ! Update update new pump well the new pump was just the same old pump which was junk to begin with which idc what they will pull here replace a junk pump with another junk pump and never fix the probnlem cause it cost them too much !
Same situation with me. My CP4 pump exploded internally, leaving shavings all throughout the fuel lines and injectors. Had to have the injectors replaced, install a CP3 fuel pump with the conversion kit and also have an Air Dog lift pump installed. All to the tune of $10,000. I just need to know where to sign up for this. Think I’ll buy another GMC product, yeah-NO!
I have a GMC Denali HD 2500 2015 it recently left me stranded on the side of the road in Austin TX i live in Fort Worth TX it had 140,000 miles on it i had to get it towed back to Fort Worth I’ve paid over 12k in parts and labor on fixing the truck my fuel pump went out and threw metal shavings in all of my injectors i had to replace all injectors and fuel pump my truck was down for almost a whole month getting worked on it’s a shame you spend so much money on a truck for it to break down on you like this it’s happend twice Already and I’m the only owner i bought the truck with 0 miles 73k for the truck and still have to fork over all this money to get it fixed when GM knee about this problem this is not right!
My 2011 Chevrolet Silverado HD 3500 (Duramax) just recent had similar failure and is currently at a dealership here in Texas. It only has 125000 miles on it, which for a diesel is literally just getting broken in….I have had numerous other heavy duty diesels in the past and they have always gotten well over 300,000 miles.
The dealership advises that it is a fuel pump issue just as is stated in the information above. In fact, the failure has left me stranded in Dallas when I live south of Fort Worth…so in addition to the expensive repair costs for the truck, I have no other mode of transportation, nor did the Chevy dealership even offer up one…which unfortunately if I was closer to home when the failure happened my local Chevy dealership ALWAYS provides a loaner vehicle but that’s not the major issue here on this. Also, the dealership repair technician indicated it could take up 2 weeks for the repair…SERIOUSLY? But again, not part of the discussion thread above.
So, what further action or information do you need for me to be included in this lawsuit. It’s sad when an over $50,000 vehicle brand new has these types of issues….one would expect better longevity from a higher priced/heavier duty vehicle.
Thank you for the time and additional information.
I have a 2012 2500hd and installed a Fass 165 Lift Pump, an CP4 system saver which just has heavier gauge screens on the regulator Incase it grenades and run diesel additive. Something no one should have to do but for $1k to save me $10k well worth it and I will probably change it to a CP3 and hold on to my receipt to get paid back.
Like many before me I have also had a catastrophic engine failure and want to join the class action law suit. I purchased a 2015 chevy 3500 hd in September of 2018 and the motor blew up within 6 months. Now I know why the dealership gave me a hand written estimate for the catastrophic failure, because they knew about the law suit. the repairs were going to cost over 16k !! I bought the truck for my transport company the high country version was 58k and due to the failure I have lost my company, income and an close to having the truck repossessed as im still trying to make payments but things are closing in FAST. I NEED HELP
How do I join the class action law suit against Chevy/GMC ? My 2012 duramax 3500 hd died in Florida, recently. It has just over 100,000 miles on it. This experience has left me penniless and owing at least 2 of my friends money. If I calculate the damage I probally spent over $3000 to wait on and get an estimate for repairs ($11- 12 000 ) to fix my truck.(cash). I have never experinced anything like this and i have ALWAYS driven Chevy/GMC vehicles and been more than happy. #Rethinking my stratagies-
Buy a cummings !
My family and I were stranded on the side of the road for 8 hours in battle creek Michigan because the fuel pump shattered coming down from a rest area. We were stranded on the side of the road with a trailer in tow, a child and 2 dogs, and 4 hours from home. Finally, a Good Samaritan offered to tow the 5th wheel to a nearby TA. It was one of the worst experiences in my life! Wound up sleeping at the truck stop and the next morning the truck was towed to the dealer. We had to leave it for repairs and try to figure out how to get home. I should have thought about a suit ages ago. I have all my emails from GM, a letter from GM offering an extended warranty, etc. whatever is going on, I want in! A great Father’s Day memory, 2017
It’s a reoccurring problem with chevy diesels its why everybody is cummings swapping them ! Cost less to put a cummings in that will run solid a million miles than an injection pump cost ! They did this to me in 99 ive put 13 injection pumps in my truck and my 99 6.5 still will not run ! It’s a 100k mile truck thats had 13 pump replacements that should be auto bought back by gm with that many issues ! Toyota has trucks with 300k miles the frame is rusty they pay 15,000 to buy back !
