I have a check engine light that came on. I took it to the dealer and they said it is a P0542 code for heating element relay. There is a technical service bulletin out for this known issue. I still have power train warranty left on my truck but they’re claiming it isn’t covered. I went as far as to add a bank ram air intake for over $1000 to help eliminate a complete engine failure. Any help would be appreciated

The 2019 to 2020 model year ram 2500 heavy duty equipped with a 6.7l cummins diesel engine has a major safety issue that could cause a stall and increase the risk of a crash. The bosch cp4.2 fuel injection pump has a very high rate of sudden failure leading to immediate stoppage on the engine and engine braking system. The pump destroys itself and takes out the rest of the entire fuel system leading to repairs in the $20,000 usd range. Fca & ram have attempted to revise the pump in late (july) 2020 to solve the issue but the failures keep occurring. For the 2021 model year, fca & ram have changed the pump entirely and reverted back to using an older, safer, more reliable design. No public announcements of neither the pump revision in 2020, nor the pump change in 2021 have been made. The issue is so prevalent that the replacement pumps and repairs generally have a 30-90 day wait period where the customer is without the primary vehicle. This problem is a substantiated safety risk. According to a texas judge in a bosch cp4.2 lawsuit, when another automaker, gm tried to dismiss the case saying the pump failure is not a safety issue, the court responded: "the worst case scenario of a truck spontaneously stalling at high speeds is not a mere inconvenience. Nor is it a mere inconvenience to spend between $8,000 to $20,000 on repairs to make the trucks fit for their ordinary purpose. The court rejects gm's suggestion that the risk of spontaneous engine failure while driving is not, as a matter of law, unreasonably dangerous, depriving the vehicles of fitness for their purpose of transportation.". Toyota agrees: "if a vehicle stall occurs while driving at higher speeds, this could increase the risk of a crash". Fca & ram have remedied the situation for the 2021 model year however, the 2019 and 2020 owners are still at risk. The federal safety agency needs to force fca to recall these trucks.
