Important Notes for Owners and Technicians

Alfa Romeo has provided specific advisories regarding the 2023 Alfa Romeo Stelvio TBM software issue and its repair:

• The message "Uconnect Box requires service." can appear for various reasons. For new vehicles recently switched to customer mode, the New Vehicle Preparation procedure should be followed. For intermittent concerns on customer vehicles, technicians should inspect the TBM, antenna, and instrument panel harness connections.
• After the TBM2 software update, the Tire Pressure Monitoring System (TPMS) warning light and a "Service TPM System" message will illuminate on the Instrument Panel Cluster (IPC). This is normal; the system will update automatically, and the warning light will turn off once updated tire pressures are received. Driving the vehicle for up to 20 minutes above 15 mph (24 km/h) may be necessary for the TPM system to receive this information.
• During the flash process, a battery charger must be installed to maintain battery voltage above 13.2 volts. The charging voltage must not exceed 13.5 volts.
• If the flash process is interrupted or aborted, it must be restarted.
