General Motors is offering financial relief to thousands of truck owners who faced a costly problem with their vehicle’s injection system. The agreement comes after numerous complaints about the CP4 fuel pump defect in certain Chevrolet Silverado and GMC Sierra models sold throughout the United States.
In a preliminary settlement worth $50 million, the company has not admitted to any wrongdoing. Still, it plans to compensate drivers with amounts that could reach $12,700 per vehicle. Curious about who qualifies for these payments or how to claim them? Keep reading for the essential details.
What This CP4 fuel pump defect means for Duramax engine owners who purchased these truck models
The issue centers on the CP4 fuel pump installed in certain Duramax engines manufactured between 2011 and 2016. This European-designed pump was not fully compatible with the diesel fuel available in multiple U.S. states, causing it to malfunction. When the pump fails, it releases metal shards into the engine’s fuel system, potentially damaging injectors, rails, pipes, and even the fuel tank. Repairs often cost drivers more than $10,000.
Below is a brief table outlining the most commonly reported damages:
| Component Affected | Typical Repair Cost | Potential Consequence |
|---|---|---|
| Injectors | $1,500 – $2,500 | Rough engine operation |
| Fuel Rails | $1,000 – $1,500 | Reduced fuel pressure |
| Fuel Tank | $1,500 – $3,000 | Metal debris contamination |
If you own (or previously owned) one of these models, you might be eligible for compensation. For many, these costs have been a significant burden.
How to file your claim and potentially receive compensation of up to $12,700
First, verify whether your Silverado or Sierra falls within the affected production years. Next, gather any repair invoices or documentation that proves you paid out-of-pocket for engine fixes related to the CP4 pump. Many owners have voiced concerns about missing receipts—does that disqualify them entirely? The answer is no. You may still proceed with partial documentation or statements from repair shops to support your claim.
Remember to look out for official announcements regarding where to submit your paperwork. Once the settlement is fully approved, an online platform will likely be made available to streamline the claims process. It’s wise to act promptly, as deadlines for class action suits can be strict.
Here’s a quick list of essential steps:
- Confirm your vehicle’s eligibility via VIN check.
- Collect repair invoices, workshop reports, or other proof of expenses.
- Submit your claim through the official settlement website once it opens.
No final date has been set for the hearing, but when the judge approves it, thousands could see a partial or full reimbursement for their repair costs. If you’re among those impacted, don’t miss this chance to potentially recover what you spent.
