NHTSA's summary

Supersedes Technical Service Bulletin Group 80 number 14-07 dated August 11, 2014. The MIL is on. Climate system heating performance is insufficient. Coolant level warning is on. Engine temperature is elevated. ?Limp Home? mode is active. Faults may be stored in the transmission control module. Coolant loss is found from one or more control valves: N82, N509, or N488. Coolant may have migrated into the wiring harness through the connector and into various control units. Climate system heating performance is insufficient due to coolant loss as a result of coolant migration in the electrical harness, faults in 08-Heating and Air Conditioning Electronics that result from coolant migration in the electrical harness, or a faulty N82 control valve.
