Bulletin 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.
About Technical Service Bulletins
A Technical Service Bulletin (TSB) is a document issued by a vehicle manufacturer to its dealers, describing a known issue with a specific vehicle or set of vehicles and the recommended procedure to fix it. Unlike recalls, TSBs are not mandatory and are typically only performed if an owner reports the related issue. However, TSBs can be an indicator of common problems with a vehicle.
