Yesterday (10/4/2018), my wife had another Multiple Systems Warnings episode. This time I was not there to reset things so I decided to call the dealer and get the fix (TSB 18-079) and well as the HV mileage update (TSB 18-069). The service adviser was surprised at my call as just a few minutes earlier, he was given notice of a recall campaign to fix these (and a couple of other) issues. I had the software updates done this afternoon (10/5/2018) and got paper copies of the four (4) relevant Service Bulletins:
18-089: EVTC & 3-way Valve software update for DTC's P100C, P0010, and P26A3 (this replaces 18-079)
18-090: Climate Control Unit Replacement
18-091: Driver Display Software Update (Mileage) (this replaces 18-069)
18-096: Warranty Information CD
The parts were ordered so that the service needed for 18-090 and 18-096 could be done in a future visit.
All the Service Bulletins are dated 10/4/2018 except for 18-091 which is dated 9/21/2018. The four mentioned Service Bulletins are all lumped together (all mentioned in all Service Bulletins) and the owners all affected vehicles (determined by VIN) will be sent a notification of the campaign.
