Two problems related to carrier/rack have been reported for the 2008 Lexus LS460. The most recently reported issues are listed below.
All four interior door trim panels, center console, and dash on my 2008 Lexus Ls460 are melting, cracking and admitting a foul odor causing nausea. Toyota issued a warranty enhancement bulletin covered by the customer support program ze6 but only included the 2007 Ls460. Having done research, other owners with the same 2008 Ls460 model through the 2014 Ls460 models are having the same issue. Toyota is refusing to cover the repairs as "not enough complaints have been filed". My vehicles in use date was September 23, 2008. I was told in early June 2018 by a local dealership service employee my car would have the trim panels, center console and dash replaced but when I called Lexus care I was told it was not included and would not be covered as "not enough claims have been filed for my year model". Seeing as how Toyota replaced them on the 2007 models, they should be required to issue a recall for the remaining year models that are having the same issues.
Cracked and/or sticky/melting dashboards (instrument panels) and door panels as a result of heat or humidity.
