NHTSA's summary
"Service Action: Retrofit of the Engine Coolant Temperature Sensor. Internal corrosion could form in the engine coolant temperature sensor. This corrosion leads to internal bridging of the contacts, which can cause an inaccurate engine temperature reading. This false reading could lead to difficulty in the engine starting and/or a ""Service Engine Soon"" lamp being illuminated."
