Open the full vehicle complaint log (all categories)The Bosch CP4 fuel pump internally disintegrated sending metal shavings throughout the fuel system. On the highway accelerating out of a toll both without warning, the truck lost almost all acceleration power and began to shudder. There weren't any preexisting warning lamps or messages. Any time after that when accelerating up to highway speeds quickly or attempting to maintain highway speeds the truck would lose acceleration and begin to shudder. When I took it to a mechanic, they informed me the CP4 fuel pump had "grenaded" and the whole fuel system needed to be replaced. If this had happened when merging into traffic or crossing at an intersection, I could have been hit because I couldn't accelerate as needed. The manufacturer (Ram) is aware of the malfunction and has issued recalls for the 2019 and 2020 years, but not 2018s which have the same exact part. The repairs have been completed on the truck and I have copies of the invoice.
