Check engine light turned on in my 2020 dodge ram 3500, I took the truck back to the dealership. According to them the Grid Heater Relay needs to be replaced & the truck could have caught on fire if we would have kept driving like that. I have done some research and saw that there has been a recall on that same part for the 2021-2023. Could it be possible the 2020 were defective also, this is a major safety concern and should be looked into. I also don’t believe the customer should be responsible for paying for this issue to be fixed when it was my family’s safety that was jeopardized.

On 12/4/23, at 6:37 am PST, we initiated remote start via the key fob. At 6:40 am pst, a flash and fire erupted from under the hood of the truck. We immediately worked to control the fire using extinguishers and garden hoses until the fire department arrived a few minutes later. They worked to put the fire out that engulfed the engine compartment and then worked to get the hood open to finish putting the fire out. The fire didn’t fully go out until the battery cables were cut.

While driving Down a paved roadway on 6/30/23 @ 5pm doing approximately 20 miles per hour the vehicle died and the dash lite up with every single message possible such as 4WD inactive, oil change due, fuel filter service required and etc. Attempted to restart the vehicle for about 25 minutes when another citizen noticed we were having issues with the vehicle so they stopped to assist us. The citizen towed my vehicle to location we were staying at for the weekend and upon arrival to the location I disconnected both battery terminals to allow the computer modules to drain/reset. After allowing the batteries to be disconnected for several hours I hooked them back up and tried starting the vehicle and was unsuccessful getting it to restart. I disconnected the batteries again for the night and returned the next morning to hook them up. after hooking the batteries back up, I was able to get the vehicle started and moved it around at the place we were staying at and allowed it remain running for about 20 minutes before I shut it off. Went and did other projects and about 5 hours later returned to the pickup to see to see if it would start since we were heading back the next morning and it started so I figured it would get us home on Sunday July 2nd. On July 2nd @ 11:30am started the pickup to leave and everything seemed normal. We drove about 5miles from the location we were staying at and were approaching an intersecting highway OR58. I proceeded out onto OR58 westbound and as we got about 1 mile down the road when the pickup died and every message was being displayed again. As we sat way off the shoulder of OR58 incident response pulled up behind us to make sure everything was ok. I told the incident responder that we were good and I was working on contacting RAM for a tow. About 15 minutes had passed and IR person walked away then the pickup started. I was able to drive the pickup about 2 more miles down the road when it died again and had to be towed.

The contact owns a 2020 RAM 3500. The contact stated that while driving at 15 MPH, the oil warning light was illuminated, and the vehicle made abnormal sounds. Additionally, there was smoke coming from under the hood of the vehicle. The contact pulled over and refilled the oil reservoir; however, the failure recurred with oil leaking from the vehicle. The vehicle was towed to the dealer and diagnosed with engine damage and connecting rod failure, which punctured the engine block. The engine needed to be replaced. The vehicle was not repaired and remained at the dealer. The manufacturer was not made aware of the failure. Upon investigation, the contact related the failure to NHTSA Campaign Number: 20V511000 (Engine and Engine Cooling, Electrical System) however, the VIN was not included in the recall. The failure mileage was approximately 213,000. The oil light did not come on until after the engine had started knocking rapidly. The engine oil also ran out quickly as well. Consumer immediately refilled the oil and drove for 5 minutes and the engine stopped knocking for a few seconds before there was louder knocking, smoke and spewing oil. Consumer had previously reported to the customer care FCA group 2 times last August about metal shavings on the fuel filter. The fuel pump continued to produce metal shavings in the filter every time the filter was change.

This Laramie trim level truck has an electronic drop tailgate with a button to drop the tailgate on the overhead console and one on the key fob. The tailgate on my truck was closed during my pre-trip and entering the vehicle. I had a trailer hooked to the receiver hitch and drove ten miles before realizing the tailgate was now in the down position and caused significant damage to the tailgate because the tailgate made contact with the trailer. With the electronic release tailgate on this particular year truck there is not a warning message alerting the driver that the tailgate is ajar. There is such an alert on newer models (2021-2022) I went to a local dealership to check. I’m sure the tailgate drop button somehow was pressed on the key fob while in my pocket entering the truck. But I did not receive any alert on the instrument cluster or even hear the tailgate open because the tailgate has a soft open feature. I see this being a serious safety concern to possibly lose cargo and cause a more serious accident.

2EA23001 · High Pressure Fuel Pump Failure
Opened Mar 17, 2023 · No close date supplied
Status: open (inferred from source dates) · Fuel System, Diesel:delivery:fuel Pump
The Office of Defects Investigation (ODI) opened PE21-021 on October 14, 2021, to investigate incidents alleging a stall/loss of motive power as a result of high-pressure fuel pump failures in certain model year (MY) 2019-2020 Ram 2500, 3500, 4500, and 5500 heavy duty trucks equipped with 6.7L Cummins turbodiesel engines. During the investigation, ODI sought to determine if the related defect allegation was limited in scope to the recalled population. After review of information request response materials from both FCA and BMW, NHTSA determined that sufficient information to identify a comprehensive recall population could not be produced by FCA and BMW.During the investigation FCA filed recalls 22V406, 22E048, 22V767, and 22E087 which include vehicles not identified in the initial subject population by ODI. ODI also received recall 21V586, involving loss of motive power due to failed CP4 fuel pumps on certain BMW manufactured vehicles. An information request letter response received from BMW indicated that failed pumps on their vehicles were caused by an interaction between pump internal components and US market diesel fuel, leading to increased slip and eventual particle-generating wear surface. Additional work will be done to identify whether a similar root cause is associated with the FCA recalled population and if similar wear dynamics occur on pumps supplied to vehicle manufacturers other than those included in the recalled population.ODI has upgraded this investigation to an EA in order to 1) determine engineering specifications of internal pump components that are correlated with pump failure leading to loss of motive power or other safety related hazards, 2) identify vehicle populations equipped with alleged defective pump variants, 3) assess if vehicles equipped with alleged defective pump variants result in an unreasonable risk to motor vehicle safety and 4) gather and review any other relevant information related to high pressure fuel pump failure associated with the subject populations of recalls 21V586, 21V880, 21E094, 22V406, 22E048, 22V767, and 22E087.Review of the above information will allow NHTSA to confirm root cause and recall remedy viability, and identify and evaluate vehicle populations equipped with pump components that may pose an unreasonable risk to motor vehicle safety.The ODI reports cited above can be reviewed at: http://www-odi.nhtsa.dot.gov/owners/SearchNHTSAID using the following complaint identification numbers: 11257550, 11351441, 11361603, 11361616, 11365300, 11365426, 11365858, 11366401, 11372337, 11373793, 11374797, 11376793, 11377871, 11378173, 11384377, 11386063, 11387018, 11399710, 11402550, 11415339, 11418868, 11418870, 11427075, 11434276, 11436807, 11437226, 11437249, 11437273, 11437292, 11437294, 11437394, 11437399, 11437403, 11437405, 11437423, 11437528, 11437565, 11437579, 11437580, 11437590, 11437679, 11437744, 11437781, 11437842, 11437993, 11438006, 11438008, 11438121, 11438138, 11438155, 11438392, 11438629, 11439359, 11439879, 11440397, 11443030, 11446542, 11448163, 11453556, 11458918, 11460558, 11469337
PE21021 · High Pressure Fuel Pump Failure
Opened Oct 14, 2021 · Closed Apr 14, 2023
Status: closed (inferred from source dates) · Fuel System, Diesel:delivery:fuel Pump
The Office of Defects Investigation (ODI) opened PE21-021 on October 14, 2021 to investigate allegations of stall/loss of motive power as a result of high pressure fuel pump failures in certain model year (MY) 2019-2020 RAM 2500, 3500, 4500, and 5500 heavy duty trucks equipped with 6.7L Cummins turbodiesel engines.On November 12, 2021, FCA filed vehicle recall 21V-880 and equipment recall 21E-094 on the subject population, identifying an `internally failed component? of the high pressure fuel pump equipped on the 6.7L Cummins Turbodiesel engine that introduced debris into the fuel system potentially causing fuel starvation and consequently an unexpected loss of motive power. Discussions with FCA identified the high pressure fuel pump equipped on these vehicles as the Bosch-supplied CP4. On December 16, 2021, Bosch filed recall 21E-101, stating the pump failure was a consequence of a manufacturer application-specific fuel system design.NHTSA subsequently identified recall 21V-586 involving loss of motive power due to failed CP4 fuel pumps on certain BMW vehicles.As a result of having received multiple recalls related to a common component, from two separate vehicle manufacturers, NHTSA?s focus shifted to determine if the related defect allegation was limited in scope to the recalled population. In early 2022, information request letters were sent to FCA and BMW to determine the root cause and consequentially identify the proper scope of potentially defective vehicles. After ODI received their information request response, FCA filed recalls 22V-406, 22E-048, 22V-767, and 22E-087. During review of information request response materials, NHTSA determined that sufficient information to identify a comprehensive recall population could not be produced by FCA or BMW. On March 17, 2023, this Preliminary Evaluation was upgraded to an Engineering Analysis (EA23-001), expanding the scope to include the Tier-one supplier and any manufacturer who equipped or installed similar high pressure fuel pumps subject to the failures observed in the recall population.The ODI reports cited above can be reviewed at: http://www-odi.nhtsa.dot.gov/owners/SearchNHTSAID using the following complaint identification numbers: 11351441, 11361603, 11361616, 11365300, 11365426, 11365858, 11366401, 11372337, 11373793, 11374797, 11376793, 11378173, 11384377, 11386063, 11387018, 11399710, 11402550, 11415339, 11418868, 11418870, 11427075, 11434276, 11436807, 11437226, 11437249, 11437273, 11437292, 11437294, 11437394, 11437399, 11437403, 11437405, 11437423, 11437528, 11437565, 11437579, 11437580, 11437590, 11437679, 11437744, 11437781, 11437842, 11437993, 11438006, 11438008, 11438121, 11438138, 11438155, 11438392, 11438629, 11439359, 11439879, 11440397, 11443030, 11448163, 11458918, 11460558
