I have a 2005 Sorento XS CRDI which has 3 faults which I believe to be caused by software.
1. Throttle sticks (the throttle is a digital transducer) when accelerating under load; i.e. 1st or second gear when declutching to change gear the throttle remains open for a short while.
2. The main selector switch for cruise control is intermittent (again another digital device)
3. The Low range 4 wheel drive selector does not work at all and I suspect this is again digital.
The car went back to the dealers whilst still under warranty but they said they couldn't find anything wrong after two days!
The car is now out of warranty but I will be taking it back to the dealer as I will be needing the 4 wheel low ratio for launching/recovering a boat. The other faults I have been 'living with'!
I believe the main digital controller is at fault and could possibly be fixed by re-programming.
Watch this space.
