2010 Dead Dash

Welcome!

This is a UK forum (primarily) and we have never had the 6-cylinder petrol RAVs here - so you are unlikely to get a response from someone with first-hand experience of this problem.

It feels like an intermittent electrical fault - that much is probably obvious - there may be more than one fault here but dodgy electrics could give rise to bizarre symptoms.

Can you clarify the normal start procedure for your car? Specifically, do you have to depress the brake pedal before pressing the start button to start the car? And, does the car have separate Accessory and Ignition On positions? We know that there is primary power available from the 12v battery - the seats can be adjusted happily. But a need to depress the brake pedal might suggest a faulty brake light switch or issue in the brake light wiring. In this case an intermittent fault could cause the car not to recognise that the brake pedal had been pressed and thus refuse to power-up the car ... just a guess ... Obviously there is scope for an intermittent fault in this area.

What do you mean when you say "no cruise control or traction control"? Do the functions not work or is it that there are warning lights showing? It is 'common' for the 4x4 light to come on in conjunction with the engine management light - but this does not necessarily indicate a specific fault with the traction control system. Cruise control is 'cancelled' by pressing the brake pedal - so it might be possible for an iffy brake light switch or wiring short to produce the symptoms of both the not starting and no cruise control - but maybe that's a bit of a stretch ...
