TIRES

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.

Vehicle died in a busy intersection coming off the freeway. Light flashed that indicated it was an issue with the electronic throttle control. The safety of myself and others was put at risk due to the posted speed of the road and multiple lanes from 4 directions. I had to remain in my vehicle to make sure I was not hit by another vehicle and due to the vehicle issue, I was impeding traffic. Lithia Dodge of Grants Pass, OR stated they could not make an appt for the vehicle to get looked at for 2 weeks out, scheduled 8/22/25. Dealership seems to think this is not an issue with safety and this issue can occur while the vehicle is in motion which is a huge safety issue. No warning lights flashed before the first one indicating the vehicle would shut down/lose all power.

Failure of hydraulic lifters and camshaft in Cummins 6.7 liter diesel engine of 2021 RAM 3500. Engine exhibited significant ticking noise and the engine does not work properly, putting the safety of driver and passengers in vehicle at risk. Vehicle is not driveable. This issue has been confirmed by the RAM dealership in Livingston, Montana. The 2021 RAM 3500 truck has been sitting at the RAM dealership for the past seven weeks awaiting parts and a fix that RAM trucks is still trying to figure out. Apparently, this has become a common problem with the RAM Cummins 6.7 liter diesels from model years 2019 through current 2025 models, including 2021. The RAM dealership in Livingston, Montana has five separate RAM Cummins 6.7 liter diesel trucks with the same issue awaiting parts and a fix from RAM.

After stopping it appeared that the front passenger tire was out of round. This was confirmed after jacking up the vehicle. Suspect internal damage to the radials. The tire had a total of 16,600 miles on it. Tire had cold pressure of 80 psi and was just checked 4 days prior to the incident. Luckily, the issue was discovered prior to a catastrophic failure, so no damage or accident occured for this particular failure.

I powered on the truck. Upon ignition check engine light, along with ABS, 4WD, traction control came on. Lights for the forward collision and adaptive cruise control illuminated.

Nexen LT235/80R17 2 blow out's and one tire failure. factory installed tires. I have had 2 blowouts on the right front of my Ram 3500. I had discount tire unmount and re mount my spare on the blown-out tire wheel (for appearance purpose) so my spare is now another brand, the spare Nexen that replaced the blow out also blew out within ~2000 miles. I took the vehicle to Walts Live Oak Ram to inspect the vehicle for a cause of 2 tires blowing in the same position on the vehicle, they also checked the alignment and found nothing. yesterday [XXX] pulling a trailer to Jacksonville I noticed about 50 miles into the trip a slight shudder in the steering wheel and I pressed on. On the return trip the shudder in the steering was substantially profound and the driver side view mirror was bouncing up and down, the passenger side was not, and my hands were getting numb, I slowed to 50 from 70mph and continued, the shuddering eased but was clearly still there. today I took the truck to discount tire Lake city Fla. and asked them to replace the Nexen as I felt it was failing from looking at the tire and running my hand along the tread it didnt feel normal and the tire was hot compared to the passenger side. I asked discount to spin the Nexen on the balancer and they did, it confirmed the tire was failing and was unable to be balanced. the new tire cured the problem. the truck today clocked 37k miles to give you some perspective on mileage and primary use is for towing trailers, 42' 5th wheel, 16' box or flatbed trailer.
