My 2022 Ram 2500 6.4L HEMI has a long crank/hard-start issue every morning. It takes 5–6 attempts to start when the vehicle sits overnight. After starting once, it runs normally the rest of the day. I also had issues where the truck struggled to start after refueling. I replaced the gas cap and EVAP purge valve, which improved the refueling issue, but the long-crank cold start continues. I suspect a fuel pump internal check-valve failure causing fuel pressure to bleed down overnight. This is common on these trucks and is a safety concern because the vehicle may fail to start in emergency situations or stall unexpectedly. No check-engine light is present. The issue is repeatable daily.” Faulty fuel pumps in these specific RAM models can suddenly fail while driving. This failure can lead to a complete loss of engine power without warning, increasing the risk of a crash.

I am reporting a recurring safety defect involving hydraulic lifter failure in Ram trucks equipped with the Cummins diesel engine (model years 2019–2024). This issue is widely acknowledged by Stellantis and multiple dealers. It typically begins with a knocking sound and has been documented in many cases to progress to complete engine failure. My vehicle has fewer than 20,000 miles. The lifters were already replaced once, which required the cab to be removed. Within less than 400 miles of that repair, the knocking sound has returned. I brought the truck to a second dealer, who confirmed the problem and informed me that Stellantis has an active STAR case acknowledging the defect. They stated there is currently no known permanent fix. This defect presents a serious safety concern. Sudden engine failure while driving, especially under load or at highway speeds, could lead to loss of power, loss of steering/braking assist, and potential accidents. In my situation, I frequently travel with family members who have medical conditions, and being stranded in hazardous or remote conditions poses significant risk. At this point, my vehicle is not reliable or safe to operate. I am requesting the federal safety agency investigate the hydraulic lifter defect in 2019–2024 Ram Cummins trucks due to the safety implications and the lack of an available permanent repair.

This is the second time this is happening, first time June 30 2023 it was towed to rainbow ram in Covington because it lost power and multiple warning lights came on, service shifter appeared in message center, truck got home and wouldn't shift, then wouldn't start. Theyouldn't find the problem I was told they detected high voltage and checked for loose connection but couldn't find any issue despite having the truck more than a week. On August 3rd while driving on i10 in Alabama the truck had a sudden drop in power and start decelerating almost every warning light came on the dash with multiple message in the message center. It is currently at tameron ram in Alabama. The put it on a computer that showed almost every control module has failed. RAM will not guarantee to provide me a rental truck and the dealer can't tell me how long they will have it. To be clear I have no complaint aboutTameron ram staff. The last message on the display said to stop the truck in a safe place and that it may not start again. While tri g to get to the dealer it was going crazy with different lights and windshield wipers turning on by themselves.

First issue (intermittent) the light control did not come on or operate the lights in the auto position to a high beam in limited visibility. The rotation knob for interior lighting would not work and the display was bright that affected seeing at night. No codes was generated and will be going to have the vehicle check out by dealership on Feb 8 2023. Second issue the truck demonstrated a short loss of power (a low grinding was heard) in two instances that resulted in low acceleration when turning across traffic lane.
