Too many chicken littles...
The 1.5T engine is great. Fantastic mix of outstanding fuel economy, and power, particularly low end torque.
Fuel dilution is mostly an issue with people living in cold climates, and driving short trips. If this describes your usage, change the oil at 5k intervals, which many of us do regardless, and rest easy.
Honda's CVT's are excellent. Bonus points for changing the fluid at 30k intervals, but it's not necessary.
A/C problems are real on the Civic, but I'm not clear on the CRV. I believe the compressor seal is the same, so be aware.
