Ram ProMaster radiator fan wiring can overheat and catch fire
critical How serious is it? About this label
This is serious — an overheating circuit can lead to an under-hood fire — but Chrysler has not told owners to stop driving or to park outside, so keep driving while you get the repair scheduled promptly.
What's wrong, in plain English
The wiring that powers the radiator cooling fan can get too hot. That overheating can damage the circuit and start a fire under the hood, even while you are just driving normally. The free fix replaces the cooling fan module and its fuse, and the dealer adds a label for the fuse box plus an insert for your owner's manual. Chrysler has been mailing letters in groups, with the last ones expected in July 2026.
What you should do
2. Call your Ram dealer, or Chrysler customer service at 800-853-1403 (recall numbers 67C, B3C, C9C), to book the repair.
3. Have the fan module and fuse replaced — the work and parts are free, even if you are not the first owner.
