What GM Trucks Are Part of the Defective Fuel Pump Lawsuit?

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. 

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.
