# Service bulletin SSM 50325 A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned. - Type: Service bulletin - NHTSA id: 10205448 - Published by NHTSA: 2021\-12\-26 - Manufacturer's number: SSM 50325 - Manufacturer's date: 2021\-12\-07 - NHTSA component: EQUIPMENT; ENGINE AND ENGINE COOLING; EQUIPMENT ADAPTIVE/MOBILITY ## NHTSA's summary Some 2021 Escape/Corsair 2.5L PHEV vehicles may exhibit an illuminated MIL with DTCs P2183 and/or P26C1 present. The vehicle may also exhibit an engine overheat message in the instrument panel cluster. Engineering is aware of this concern and is working on a solution. Continue with checking the engine coolant level, inspect the cabin heater coolant temperature sensor \(ECT sensor 2\) connector for contamination and perform Workshop Manual \(WSM\), Section 412\-00 pinpoint test AQ. If no concern is found and the vehicle does not exhibit DTC P1285 or P1299, clear the DTCs. If DTCs P1285 or P1299 are present, perform normal WSM diagnosis and repair. Inform customers that Ford is working on a resolution and that the vehicle is safe to drive. Monitor OASIS for updates. Once the solution becomes available, contact the customer and set up a service appointment. ## The document - [NHTSA's copy of the document (PDF)](https://static.nhtsa.gov/odi/tsbs/2021/MC-10205448-0001.pdf) - [If that address does not open, try this one](https://static.nhtsa.gov/odi/tsbs/2021/MC-10205448-9999.pdf) The document is the manufacturer's.
