Sidecar: Automotive assistant

Mar 19, 2026

▶ Improved account management When a vehicle was registered both as an offline vehicle and as part of a Connected Account, weird things would happen. Weird things should no longer happen. You can now also remove vehicles and accounts directly from the account's page. ▶ Expanded OBD support Some vehicles respond to standard commands in non-standard ways. Sidecar now intelligently handles negotiating with those vehicles automatically, improving the likelihood of successful scan sessions. ▶ OBD Scanner stability When a vehicle's VIN can't be detected, Sidecar re-attempts the handshake sequence a bit later. Prior to this release though, these reattempts were barging into the scan session with a big "OH YEAH!", obliterating scan session context and putting the scanner into an odd state that was often unrecoverable. The handshake sequence now politely interrupts the parameter loop. ▶ Scan session debugging Scan logs now record detailed session events, making it significantly easier to diagnose scaner problems during onboarding. Full release notes: - Added the ability to remove Sidecar vehicles/accounts from the account page. - Fixed race condition i OBD signal loop that caused polling for signals in the middle of a handshake re-attempt, breaking both sequences. - Fixed bug where Connected Account vehicles would incorrectly show up as not onboarded. - Fixed bug where registering a vehicle as both an offline vehicle and through a Connected Account would result in undefined behavior. - Fixed bug where tapping "Connected scanner" win the vehicle page would do nothing. - Fixed bug where the Membership button didn't show the TestFlight notice. - Fixed bug where the Terminal would not dismiss when the scanner disconnected. - Fixed bug where the VIN handshake sequence could break signal polling and terminal initialization sequences. This specifically affected vehicles where the VIN cannot be automatically detected. - Fixed bug where turning off BTLE or Wi-Fi connectivity would not disconnect the connection, resulting in a phantom connection to the scanner. - Fixed bug where the vehicle page would display an error when Sidecar first launched. - Modernize the Terminal UX to be more performant. This should address both the crasher and the hitches when opening and interacting with the terminal (i.e. opening Terminal should be stupid fast now) - Scan logs now include session events to help with debugging weird scan sessions. - Updated Polish translations.
