Defect investigations
High pressure fuel pump failure
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, the federal safety agency 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 the federal safety agency 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.the federal safety agency.dot.gov/owners/Searchreference 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

Both front ball joints wore out at 20,000 miles The 3rd break light leaks into the cab at 26,000 miles & won't be warrantied even though there's an active recall for our same truck, same part just different model
I have had two tires separate in the past couple of months with less than 24000 miles and 5 years old. I filed a complaint with Nexen and they sent a partial payment for the first one but rejected the second claim that happened less than 500 miles of the first claim. They claim the tires are separated because of the low miles on the truck and it is not driven enough. Less than a year ago my brother had the same issue with the same tires and truck with similar mileage and was sent a check for 6 new tires. I have additional photos and photos of the other tire as well as emails with Nexen and XXX Sr. Quality Analyst © [XXX] [XXX] ® [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
While driving my truck I noticed my mpg gauge was showing 0 mpg. Then I realized my "miles to go" gauge was reading "low" even though I had plenty of fuel in the tank and my fuel gauge was showing 3/4 full. Even though I use my truck as a commercial vehicle, and drive coast to coast, I was luckily only a couple hours from home, so I kept driving to try to make it home. I did make it home, but during that time, my "check engine light came on along with my "low fuel warning" light. I also realized during that time that my odometer had stopped working. It wasn't showing any numbers at all. When I got home, I checked online to see if anyone else had heard of this problem, or how to fix it. That's when I realized just how common this problem is. Even though my truck is used in the US and my mileage is calculated in miles, the odometer is programmed to stop working at 1,000,000 kilometers, which is 621,369 miles. Who would know or expect this to happen? I called several independent garages, all of which refused to attempt to fix an odometer problem because of the legal implications. I then called several Ram dealers who all told me they had never heard of this and would have to call FCA for advice on how to fix it. After two days of waiting, my local dealer called me back and said they could give me an appt a week later to diagnose the problem with my truck. They said FCA knows about the problem, but to fix it, it has to have a new gauge cluster installed. Nobody I talked to was able to tell me if the truck was safe to drive or why Ram wasn't warning owners of this problem when their trucks reached such an odd number of miles. When they replace the odometer, it will start over again at 0 miles and a sticker in the door jamb stating that the odometer was replaced at 621,369 miles, as if anyone would think to look in the door jamb for this sticker. The reason so few other drivers are going through this problem is because they are buying an OBD reader and resetting it.
The contact filed the complaint on behalf of the customer, who was the owner of a 2021 Ram 3500. The contact stated that while the owner was driving at an undisclosed speed, the vehicle caught on fire. No warning lights were illuminated.

The vehicle was later towed to the independent mechanic. No injuries were sustained. In addition, the contact stated that the transmission was replaced by an independent mechanic. The failure occurred the following day after the vehicle was released by the independent mechanic. In addition, the owner of the vehicle had received a recall notification the federal safety agency Campaign Number: 23V060000 (Electrical System). The manufacturer was not made aware of the failure. The failure mileage was approximately 99,000.
