What RAM Engine and Cooling Recalls Involve Stalling or Fire?
RAM engine and cooling recalls cluster around diesel stalling, engine damage and fire risks. Two tone wheel notices cover 3.0L diesel Ram 1500 trucks: 2014–2018 in August 2020 and 2014–2019 in June 2023. A separate EGR cooler notice covers 2014–2019 Ram 1500 and 1500 Classic trucks with 3.0L Eco Diesel engines. The 2019–2020 Ram 3500, 4500 and 5500 cab chassis with Cummins 6.7L High Output engines appear in both warmup protection and low-oil warning software notices. Other cases involve ECM short circuits in specified 2022 Cummins diesel trucks and an overheating radiator fan circuit in 2018–2026 ProMaster vans.
Warning signs to watch for
- The August 2020 tone wheel recall: the engine may stall.
- The June 2023 tone wheel recall: the engine may stall.
- Z87: loss of drive power.
- Y21: engine calibration software may fail to warn about low oil volume.
Can you keep driving? What the notices say
The supplied RAM engine and cooling notices do not tell owners to stop driving, and none includes a park-outside instruction. The August 2020 and June 2023 tone wheel notices identify engine stalls as a crash risk, while Z87 identifies loss of drive power. The EGR cooler, W57 warmup protection, Y21 low-oil warning and October 2025 ProMaster fan circuit notices identify fire risks. These descriptions explain the consequences of the defects; the notices do not provide a statement that continued driving is safe.
What the free repair involves
Free remedies include EGR cooler replacement with intake manifold inspection and replacement as necessary; W57 and Y21 engine calibration updates; PCM updates for the tone wheel recalls; and ECM replacement for Z87. The October 2025 ProMaster notice specifies cooling fan module and fuse replacement, a manual addendum and a power distribution center label; its supplied excerpt does not state cost.

Common questions
What repair do the RAM diesel tone wheel recalls specify?
The August 2020 notice specifies a free PCM software update that maintains propulsion using the camshaft position signal if the crankshaft signal is lost. The June 2023 notice also specifies a free PCM software update to maintain propulsion.
Are the warmup protection and low-oil warning problems the same defect?
W57 describes inadequate warmup protection that can damage connecting rod bearings and the engine. Y21 describes software that may not warn about low oil volume. Both specify engine calibration software remedies for affected 2019–2020 Cummins High Output cab chassis trucks.
What does the Ram 1500 EGR cooler repair include?
The October 2019 notice specifies replacement of the EGR cooler, free of charge. Dealers also inspect the intake manifold and replace it as necessary. The affected trucks are certain 2014–2019 Ram 1500 and 1500 Classic pickups with 3.0L Eco Diesel engines.
