Official summary
Hyundai Motor America is currently investigating an ongoing auto mode update concern with software GDS event #1243. Some vehicles are not being able to complete the update after multiple attempts. Technicians may experience consistent cluster speedometer software upgrade failures when attempting to update to the latest version. A revised version of the software is currently in development to address the update failures and recover any failed modules. We will provide an update once the issue is resolved and the suspension is lifted.
Vehicles covered
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
