On the 2004-2008 Acura TL, the dashboard material on 2004-2008 TL models develops deep cracks and a sticky, melting surface texture from prolonged sun exposure. The issue is caused by the plasticizer in the dashboard material breaking down under UV light, creating an unsightly and sometimes reflective surface that can obstruct the driver view.
Replace the dashboard assembly with a new unit — Acura extended a warranty program covering dashboard replacement at no cost for affected VINs. Contact your Acura dealer to check eligibility. Aftermarket dashboard covers can mitigate the cosmetic issue but do not fix the underlying material degradation. Use a windshield sunshade to slow progression.
