The issue extends to model year 2006-2010 Carnival 'VQ' (of which 14,803 vehicles are affected) and 2006-2009 Sorento 'BL' models (of which 3288 vehicles are affected).
Affected models were available for sale between 1 December 2005 to 31 December 2010.
Lodged with the Australian Competition and Consumer Commission (ACCC), the defect relates to the Hydraulic Electronic Control Unit (HECU) that can remain electrically-live even after the vehicle has been turned off.
If moisture enters the unit, an electric short circuit can occur, possibly creating an engine compartment fire that may increase risk of injury to vehicle occupants and other road users.
The HECU controls vehicle safety systems such anti-lock braking, electronic stability control and traction control, however CarAdvice has been able to confirm the risk only extends to a fire hazard and that these features cannot be compromised prematurely by moisture as the unit has inbuilt fail-safe mechanisms.
