Alright, this is pretty huge news for you Duramax owners. Check this out—General Motors has agreed to pay a $35 million settlement to LML Duramax owners. Watch this video from start to finish, because I’d be very interested to see how many people actually qualify for this. Let us know in the comments after you watch the whole video if you qualify. If you don’t qualify, also let us know—I’m curious to see that as well.
Now, let’s talk about the reason for the lawsuit. GM decided to put the Bosch CP4 injection pump in the LML Duramax diesel engines from 2011 to 2016. Unfortunately, these Diesel Injection pumps have been failing left and right since 2011. GM knew there was a problem but continued to sell these trucks. These pumps are like ticking time bombs. After years of fighting, a lawsuit was established, and now we have some answers.
I’ve got some good news here, but unfortunately, it doesn’t count for all 50 states. If you’re one of the eligible states, it’s a huge win for you. I’ll explain the CP4 failures, the lawsuit, and ways to combat this issue if you don’t qualify.
To narrow this down, we’re talking about 2011 to 2016 GM trucks with the 6.6L Duramax diesel engine. The CP4 Diesel Injection pumps are prone to failure. When they fail, they send metal shavings into the injection system, which is a high-pressure system (around 25,000 PSI). Everything the fuel touches may need to be replaced—injectors, CP4 pump, diesel fuel filter, fuel tank, fuel lines—it’s a nightmare. Some repairs can range from $12,000 to $16,000. In some cases, it might even total your truck’s value, especially for people using these trucks for work or travel.
If you qualify for this lawsuit, you could receive up to $112,000. If you don’t qualify, I’ll discuss ways to prevent this from happening.
Now, let’s get into the details of the lawsuit. Owners of certain Chevrolet and GMC trucks can claim cash from the $35 million settlement. Payments are estimated to range from $400 to $12,700. This news became official on October 1, 2024.
The lawsuit claims that GM’s model year 2011 to 2016 Chevrolet Silverado and GMC Sierra trucks with a 6.6L LML Duramax engine were equipped with a defective Bosch CP4 high-pressure diesel fuel pump, which is very fragile and prone to failure. The lawsuit doesn’t involve personal injury claims, and GM denies any wrongdoing. The settlement was agreed upon to avoid the cost, risk, and delays of further litigation.
Now, who is considered a class member? You are a class member if you purchased a class truck from a GM-authorized dealer in California, Florida, Illinois, Iowa, New York, Pennsylvania, or Texas between March 1, 2010, and September 13, 2024. Eligible trucks include 2011 to 2016 Silverado or GMC Sierra diesel pickup trucks with a 6.6L Duramax engine and Bosch CP4 high-pressure diesel fuel pumps. You can check your eligibility by entering your VIN into a database, which I’ll link in the description.
What does the settlement provide? Here’s a quick breakdown:
– $30 million will go to the repair fund for class members who paid out of pocket for CP4 repairs that were not covered by warranty. Payments could range from $635 to $2,712.
– $5 million will go to the former owner fund, for those who no longer own their trucks. Payments could range from $400 to $800.
– There’s also a partial repair reimbursement program that provides 50% reimbursement for future CP4 repairs performed at GM-authorized dealerships, within 12 months after the settlement’s final approval or before the truck reaches 200,000 miles, whichever comes first.
The deadline to file claim forms is six months after final approval, which could be as early as July 21, 2025. The court will hold a final approval hearing on January 21, 2025.
If you’re not part of the lawsuit or want to opt out, there are still ways to prevent CP4 failures:
1. **Diesel fuel quality:** Be mindful of where you get your diesel fuel. Truck stops often provide better quality fuel than smaller gas stations. Avoid places where diesel might be watered down.
2. **Regular maintenance:** Change your diesel fuel filters at every oil change, or at least every 5,000 to 10,000 miles.
3. **Diesel lift pump:** Lift pumps help remove water, dirt, and air from your fuel, ensuring cleaner diesel is delivered to your injection system.
4. **CP3 conversion:** If you can afford it, consider converting your CP4 pump to a CP3, which is far more reliable. I offer CP3 conversion kits on my website.
For those who don’t qualify for the lawsuit but still own an LML Duramax, I recommend taking these preventative measures before your CP4 pump fails. The 2017 and newer Duramax engines (L5P) don’t have this issue, so if you’re thinking of upgrading, that’s a solid option.
That’s it for now, guys. Let me know in the comments if you qualify for the settlement. I’m curious to see how many people actually do. Before I go, I’m also excited to announce that we’re now offering RDS turbos, along with other diesel performance products.
