I wouldn't like this problem passed on to anyone, it truly sucks when you fork out so much money for what you think would be a reliable family car! After 2 weeks of our Rav being at the Toyota Dealership Service centre they called yesterday and said the bad ECU had been replaced along with a faulty coil (faulted due to the ECU fault apparently - dubious) and the car was now running perfect but they suspect the transmission is damaged and not safe to drive. I decided to go to the dealership and inspect the car myself. I spoke to the mechanic for about 20-30minutes in the car while it was idling in drive (didn't miss a beat) and then drove it only to find that it wasn't struggling to change/select the right gears but only slipped into 3rd from 2nd (ever so slightly) when you were to really floor it. After being told on the phone that the car needed a new transmission the mechanic then said you could probably nurse it or never have a problem with it for the next 10 years, he was merely flagging the problem he'd found/noticed. I thanked him for the thought but told he we'd never drive it like a Supercar and I had nothing to lose to drive to it 'may or may not' fail completely. He agreed! After some discussion of the situation and how unhappy I was over the ordeal they believed Toyota 'should and could' fix the gear box free of charge (sceptical they said this though to see the back of me and we'll see). So, 2 weeks later, they replaced a fuel filter (as they believed it was contaminated fuel which caused the stall/idle/power loss), drained the fuel tank and aired it, replaced the ECU, cleaned/lubricated the valves and then replaced just one coil at a total cost of $2800 gst included! I can't help but wonder if maybe it was just a faulty coil and I could have been charged only $400-600, but they are the experts and you take your car to them for honest practical service right?! $2800 seems like a lot of money to be ran-around over 2 weeks, but in the end I'm happy to have the car back in my own hands and will monitor it very closely and decide where to next. I am still unhappy with the service I received and the lack of information I was relayed and worst of all Toyota Australia's lack of support and responsibility for a blunder they are certainly aware of (ECU/Transmission). As much as I love the Rav4 I'm now faced with the decision of either riding this problem through or buying a different vehicle, not sure where I stand yet :( Cheers, Shagsy. Ps. I have kept a record of everything I have gone through so if any further problems with the Transmission arise I'll definitely be taking it further, like Consumer Affairs,
