I forgot to turn off the engine (push button) after parking. The engine ran for more than 5 hours until I returned. Unlike the traditional key that most of us remember to take it after parking. Removing the key will turn off the engine. I am of the opinion that this a critical safety issue: 1. The engine could overheat in hot summer and may even catch on fire 2. Anyone can drive the car away without the key. Low or totally no key signal means the driver is not near to the car. The engine should not be running at all. For the least, there should be should be some loud alert. The Rav4 built-in technology has an auto shut off feature on acc mode after certain period and remote engine start/stop feature. One cannot start the car without the key nearby. Why cannot Toyota incorporate the auto off feature on the key signal level, I. E. Below certain key signal level turn the engine off automatically. I have reported to Toyota. It appears that Toyota is not going to do anything at this moment.
