Looking at your profile you live in the Dominican Republic?
I take it the weather there at the moment is very warm? Only reason I ask this is it could be an Autobox related fault. When was the autobox fluid and filter changed? Here in the UK our service schedule makes no mention of the autobox fluid change intervals. Except that there is mention in the YRV manual that the autobox fluid needs changgin every 6 years. Yet there are memebrs on here from Malaysia who swear by every 1 to 2 years depending on how hard the car is being driven. There have been issues where some members who drive YRV Turbos (Autobox only cars), where a flashing 'D' has appeared to when changing gears the gears not engaging causing the rev counter to shoot up. Again no conclucsions on why, except that without proper maintenance on the gearbox will cause issues witht he internals. You wouldnt skimp on an oil and filter change on your engine.
