    The contact owns a 2020 Ram 3500. The contact stated that while driving at various speeds, the vehicle made an abnormal ticking sound.

The contact stated that upon taking the vehicle to an independent mechanic to be serviced, the mechanic informed the contact that the high-pressure fuel pump installed on the vehicle was not the recall part, but the same defective part.

The manufacturer was notified of the failure and referred the contact to the dealer for assistance.

    Codes: P2002, P242F, P2463, P1451 Failures: DPF, Charge air cooler leak, PM sensors, EGR internally cracked, Catalytic Convertor, Pink tinged oil, strong diesel odor in oil - post failures. Erratic def gauge readings, unstable idling, clunking downshift when exhaust brake decelerates, warm up stumbling. Power reduced, see dealer (over and over and over and over). Limp Mode (5 MPH). Permanent ticks/taps from front left motor, front passenger wheel well, passenger side mid-truck. Extremely loose gear shifter plus an occasional “Vehicle Not in Part” message on the dash display. Manufacturers Service Center (local and ONLY Ram dealership) has reproduced the issue. Independent Diesel Mechanic shop also reproduced. Service center and Independent shop both inspected. The safety issues of a 5 MPH limp mode and risk of sudden engine stalls while driving in traffic, especially on an interstate should be fairly self explanatory… As is a constant “Power Reduced See Dealer” problem, when your truck is used to do what it’s designed to do… Tow large loads. As is an extremely loose gear shifter that doesn’t always properly register as “in Park”. The date listed below is simply the date of the very first occurrence. It’s not a representation of every date after. The most recent date was just last week.

    Reoccurring messages regarding DEF, Exhaust Regeneration, and DPF, causing more and more frequent ReGen for longer and longer. Numerous trips to various Ram dealerships resulting in codes being cleared and then being told it was a software issue. After 2 years of this intermittently happening, we experienced an extended Regen that lasted hours and did not clear out the error code. Ram dealer in Utah charged $280 to do a stationary regeneration and once again clear out codes. Less than 6 months later with more and more Regens, a failed regen sent truck into Low Power Mode (losing the ability to tow or excelerate quickly). We ended up having to take it to a Ram dealer over 2 hours away in S. Atlanta to have them take it apart and tell us that the factory installed wiring harness rubbed a hole in the charged air cooler boot which was then causing failed regeneration of the diesel particulates causing the filter to fill. Dealer clearly stated that had any other dealer done a visual inspection of the physical components they would have seen this occurring. We filed a claim and opened a case with Ram for the $4500 repair and waited 8 days with no response to 9 phone calls. The same day we authorized the work, we receive the coveted return call to start the process, but once the customer service rep found out we had already authorized the work we were advised that case would be closed and we would have to open another case for reimbursement. So we started the whole process again, submitted all of the documentation and paid receipts and have been denied. All attempts to contact a supervisor or manager go nowhere and Ram customer service is rude and unhelpful and went as far as to tell us that our mistake was having the vehicle repaired (as if we are just going to let an $80k vehicle sit indefinitely in an unusable state).

    I live in northern California near San Francisco, and we were traveling from Cottonwood, AZ back to our home. Back in June of 2023 we were traveling near Kingman, AZ and had the front passenger tire explode, almost losing control of the truck and trailer. We were at 19524 miles on the truck. At the time I thought that maybe I had hit something. But two months later I took the trailer to Carson City, NV for work and just before I got into Reno the truck started to shake from side to side in the front and the next day I took it to a tire shop and they told me that the driver’s front tire was getting ready to come apart and I had only put about 800 miles on the truck since the first tire had exploded. This was when I realized the issue was the tires. I immediately had all 6 tires replaced. You can find a lot of bad comments about these tires on-line with comments like what happened to me. EXAMPLE [XXX] In response to your questions 1.I don’t have the tires that died just pictures. 2.After the blowout steering was difficult. 3.No Dealer confirmation. 4.No inspections. 5.Before the first tire exploded for about 20 miles I noticed a vibration in the front end. But just thought it was just the road. Tire Size - LT235/80R17 INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
