We have a 2017 Altise and after a day parked in the Sun we found a melted patch on the dash. Toyota have inspected the car and say that it is caused by an environmental factor and not under warranty. The only environmental factors anywhere near the dash, have been the Sun and car detailing two months prior to the problem arising. We have obtained legal advice about how to proceed: Complaint to ACCC about the general issue and individual action at VCAT to argue that the product, car dashboard in this case is not suitable for purpose as detailed within the Australian Consumer Law. We have commenced these actions, because even if we use a dash cover, the problem is still there and will affect the cars resale value. Aside from this, other parts of the interior are made from the same material and could possibly deteriorate in a similar way. Murray. Point Cook.
