For Your Information - resolved a parasitic drain of the battery
For about 6 months, the car battery in our 2016 CRV EX would not have enough power to turn over the engine. The night before it would be at 12 volts and in the morning it would be at 8 volts. The battery was replaced but the problem continued. I noticed that when I approached the CRV with a FOB, sometimes but not always, the car would auto-unlock without me pressing the FOB unlock button. If this happened in the evening, the battery would be low in the morning and could not turn over the engine. The dealer ran a diagnostic test ($180 US) and found the driver's side door handle was causing an electrical short, which would repeatedly send a signal to the circuit board that controlled the Smart system.
The handle was replaced ($600 US) and the parasitic drain of the battery stopped. It's been 5 months and the dead battery issue has not returned. The service advisor said that they have started to see this happen in older CRV and Civic.
