It's payday for Chevrolet Silverado and GMC Sierra owners 💸
Reportedly, the Bosch CP4 fuel pump wasn’t designed for American diesel. American diesel provides less lubrication than European diesel, so it causes the pump to run dry.
As a result, the pumps create metal shavings and particles that cause catastrophic damage to the fuel system and engine. Plaintiffs shared that out of pocket repair costs reached up to $15,000 and that GM knowingly sold the trucks with faulty pumps.
Owners of 2011-2016 Chevy Silverado HD or GMC Sierra HD trucks with the 6.6-liter V8 LML Duramax engines purchased from a General Motors dealership between March 1, 2010, and September 13, 2024, may qualify.
