I realise this is an old thread but I thought I would add my comments anyway. When my 2009 SR5 was about 5 or 6 years old the firewall insulation started to break off in small pieces. 2 years later it was falling off in big chunks and the soundproofing was also coming away. Needless to say Toyota aren't interested, unless of course I am happy to pay $3000 for them to fix it!alexisdmtr wrote:Same thing happened to me also.Good thing it was still under warranty and had it replaced.Bad thing now is i hear all these tiny stupid noises from in the dash that drive me crazy due to the great workmanship toyota mechanics have
Some of you have suggested that it might be the heat and general wear and tear. I owned a Prado in Dubai for many years. When I sold it, it was about 11 years old. The heat and humidity in Dubai exceeds that of most Australian conditions and there was no evidence of any damage to the firewall insulation. I also own a Corolla that stands in the sun in Brisbane most days, it is 13 years old and also no damage/issues with the insulation.
I would guess that Toyota used a substandard product/adhesive on the Hilux and as expected are washing their hands of the issue.
