NHTSA Complaint #11700252 — 2021 RAM 3500

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.
