RAM 4500 warranty claim denied?

A denied warranty claim on your RAM 4500 can feel like the end of the road, but it often isn't. Manufacturers are required to file service and repair communications with the National Highway Traffic Safety Administration (NHTSA), and for the RAM 4500 (2008–2025), 1,093 such communications are on record, including 12 formal warranty extensions or service campaigns. These cover known issues such as Diesel Exhaust Fluid (DEF) freezing, urea delivery module failures, rear axle assembly replacement, diesel particulate filter (DPF) sensor problems, and air trapped in the steering damper.

When a dealer denies a claim, the decision is frequently based on incomplete documentation or a narrow reading of the warranty terms, not a final determination of your rights. Because the manufacturer has already acknowledged these categories of defects in its own filings, a denial connected to one of them may be worth a second look.
