What RAM Electrical Recalls Involve Fires and Missing Dashboard Information?
⚠ 2 carry a park-outside (fire risk) advisory.
RAM electrical recalls repeatedly involve diesel heater relay fire risks and instrument displays that fail to communicate safety information. The relay notices cover specified Cummins 6.7L diesel pickups and cab chassis vehicles across 2021–2023. Display problems include missing driver warnings in the 2019 Ram 1500, blank or failed instrument displays in specified 2025–2026 trucks, and an incorrect brake warning light in specified 2026 trucks. Other problems are distinct: a 2019 Ram 1500 auxiliary battery connection can overheat, certain 2018 Ram 1500 and ProMaster vehicles can stall, and 2024–2025 ProMaster BEVs can lose drive power. ProMaster wiring also affects left rear lighting.
Warning signs to watch for
- The May 2018 cruise control recall: the vehicle may maintain speed or accelerate despite attempts to deactivate cruise control.
- U87: the vehicle may stall or fail to start.
- The October 2025 ProMaster BEV recall: loss of drive power.
- B4C and the December 2025 display notice describe a blank instrument display; 35D describes display failure.
- 79C: the instrument panel may display an incorrect brake system warning light.
Can you keep driving? What the notices say
Three notices give parking restrictions: March 2021 says not to park inside buildings; October 2021 says park outside buildings or structures, away from other vehicles, until repaired; February 2023 says park outside and away from structures until repaired. The March excerpt is truncated. None gives a stop-driving instruction; the remaining notices also do not tell owners to stop driving. The May 2018 cruise control notice advises owners to stop using cruise control. That instruction applies specifically to that recall.
What the free repair involves
Free remedies include securing V17 auxiliary battery fasteners; software inspection and flashing for the May 2018 cruise control recall; PCM replacement for U87; and relay replacement for February 2023. Display remedies include free cluster replacement for V83 and 79C, inspection with software update or replacement in December 2025, and software updates for 35D.

Common questions
Which RAM electrical recalls tell me to park outside?
The March 2021 relay notice advises against parking inside buildings in its supplied excerpt. The October 2021 notice specifies outside and away from other vehicles. The February 2023 heater relay notice specifies outside and away from structures until repair.
Can these RAM electrical fires happen with the ignition off?
V17 says the 2019 Ram 1500 auxiliary battery problem can cause a cabin fire even with the ignition off. The October 2021 and February 2023 diesel relay notices also describe fire risks with the ignition on or off.
Do RAM instrument display recalls require a new cluster?
V83 and 79C specify instrument cluster replacement. The December 2025 notice calls for inspection and a software update or cluster replacement as necessary. Recall 35D specifies an instrument panel software update. These notices describe their remedies as free.
