The Hyundai Sonata has been in continuous production since 1991, with multiple generational updates bringing evolving glass specifications. Earlier models from the 1990s and 2000s carry straightforward toughened rear glass, though some variants feature integrated heating elements.
From the mid-2010s onwards, later-generation Sonatas introduced more advanced rear-window options, including heated glass with integrated antenna for radio reception on certain trims. These integrated features require careful matching during replacement to ensure all functionality is preserved.
Because the Sonata's rear window is toughened glass, replacement involves managing shattered shards — a significant part of the job. Your technician will clear accessible debris, but professional interior detailing afterwards is recommended for thorough shard removal.
