Yes. As already stated, it was due to software programming and cold weather short drives. There was software updates on all 2019 CR-V's moving forward and a TSB to update the '17/18 models as well as the warranty extension, like you mentioned.The 2017 and some 2018 CRVs had OD problems, some pretty bad.
There was a leaky infection problem, plus some software programing short falls. Both were rectified under warranty and the warranty extended.
The same motor had been in the civic for two years prior to being used in the CRV without OD issues, it's was in the Accord too.
