Honda kept embedded modems off many non-Touring, non-hybrid trims far longer than other major brands. On those cars, HondaLink works over Bluetooth through your phone, so the car itself has nothing to transmit with. But Honda equipment varies heavily by model, year, and trim, and recent hybrid and Touring trims carry built-in telematics units that communicate by cell signal. Honda publishes a HondaLink compatibility checker by year, model, and trim; use it, run the VIN, and inspect the car. This pick is conditional on that verification, every time.
The mechanical caveat is separate from privacy: Honda’s documented warranty extension for 1.5L turbo oil dilution covered the 2016-2018 Civic and 2017-2018 CR-V. Similar problems in the 2018-2022 Accord have been alleged in class-action filings but are not part of that documented extension. Prefer the naturally aspirated 2.0L engines and the issue disappears entirely.
