Tire is Nexen Roadian AT Pro LT235/80R17 Load Range E. Original Factory installed tires on 2019 Ram 3500 with dual rear wheels. Purchased the truck new in June 2020. All 6 tires on the truck are identical and had approximately 14,000 miles on them when the driver's side front tire failed. The tires were recently rotated approximately 3-4 weeks prior to failure. The tire that failed was previously located on the Passenger Side Front prior to rotation. I began noticing vibration in the steering wheel at speeds approximately 40-45 mph and higher. I monitored this vibration for a few days in various driving conditions in an attempt to diagnose the problem and noticed that the vibration increased with vehicle speed. Soon, the problem became worse and the entire vehicle began vibrating. The last day of the evaluation period I was towing a Tandem Axle 16ft open Car Trailer with an SUV loaded on the trailer at speeds as high as 75 mph on the interstate. The next day I took the truck to the local dealer who informed me that the steel belt had separated on the inside of the tire and would require replacement. After conducting research on tire separation, I discovered the serious safety concern where the tire could have blown out which would have surely caused a serious accident. I also discovered that this separation failure is very common with this same combination of Nexen Tires on Heavy Duty Ram Pickup Trucks. I had the spare tire mounted until an identical replacement tire was delivered to the dealer for install. I paid $282.42 out of pocket for the tire replacement and after arguing with the dealer, they filed a warranty claim with Nexen. Weeks later I was informed that they have offered to reimburse approximately $113, but to date I have not received any funds and I still have 6 Nexen of these Nexen tires on my truck plus the spare.

In August 2021, my truck started pulling to the right and bouncing. I took to dealership where got vehicle. On September 1,2021 they rotated front tires to rear outer spots. The truck stopped pulling but still bounced. A week later went to Dr. appointment and when got back the tire that was on right front and moved to right rear outer spot had a knot in side wall as well as wire sticking out. There was only 17,479 miles on the truck at the time of rotation. I had that tire taken off and spare put on. Truck still bounced like bad tire still on rear of it. Then on October 20,2021 the other tire that was moved from left front to left rear outer tire split in the tread and blowing out. I contacted the dealership about the issues with the tires but they said it's the customer's responsibility to file warranty claims. In trying to find a dealer of Nexem tires, which I've not been able to in this area, I found a lot of complaints on these tires. Now it's going to cost me almost 2000.00 dollars to replace all 7 tires.

NEXEN LT235/80R17 2019 Dodge Ram 3500 Dually We have read many horror stories about these stock tires from RAM. The RAM dually and other sites are full of photos and stories of the tires failing. These truck are used for towing large RV and other trailers so the risk due to failing tires is huge. We had hoped to get a few miles out of them before replacing them for peace of mind. Didn't happen though we had the front and inside dual on the passenger side fail at 14,866 miles. The front began to wobble and shake the front end of the truck. I noticed it on 10/12/2021 and on the 13th the truck was shaking so badly I drove the 15 or so miles to Discount tire at 30mph. Discount tire inspected the tire and immediately noticed the tire belts were separating and the tire was about to blow apart. They then found the inside passenger side dual was separating as well. We pulled and replaced all 6 tires. No way we could trust our safety to the RAM stock NEXEN tires. Please look into this further. The number of reports does not reflect the numbers of failures on the road. Many of the truck buyers just immediately replace the NEXEN tires on delivery of their RAM trucks! $200 for a new front end alignment and $1,600 for tires on a new truck but we are safe.

EA23001 · 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
