ECO mode ON or OFF

Just curious how many drive with the ECO mode turned ON? Will driving with the ECO turned ON affect the wear on the car?

I drive with it on to save gas. I think the car is designed to be used with ECO on so I don't believe it will have adverse wear on the car.

I always leave it on, here in Bogotá traffic is terrible (Even worse than L.A) and it really helps me save gas and reduce emissions (Yeah, I'm kind of a green dude). I don't think it affects the engine at all, those engines were designed with that system in mind.

I leave it on now that I'm use to it. As mentioned, the car is designed for the ECO mode so I wouldn't worry too much about excessive wear and tear. Keep in mind, the ECO is only on when all desired conditions of the car's system are met (engine temperature, health of the battery and charging system, etc.). If anything in the chain isn't right then the ECO mode will remain off.

Anyone notice that when outside temperatures are cold (18 degrees) that the car does not shut off when stopped in ECON mode?

The way how it works is it will go full ECON only if all conditions are optimal. ECON is always on automatically as indicated by the yellow ECON light when you start the car (assuming you didn't shut it off) the dash. But this doesn't mean the conditions are optimal for stop/start right away. You'll know it's ready for stop/start when the yellow ECON turns green. That's when the stop/start feature is active. Since everything remains on when the engine has stopped (radio, heater, lights, computer, and whatever else was on when you're driving), in order for the stop/start to be active the engine has to be in optimal operating temperature, the battery needs to be fully charged and the charging system is healthy. Since the car is brand new I'm going to assume the battery and alternator are good and that the only thing preventing it from going active is the engine temperature. Even if the engine temperature is at optimal, extreme cold outside temperature may drop it down quickly as soon as the engine is off. This is probably why your car won't shut off even though the ECO feature is on.

I feel like the constant turning on and off of the vehicle would wear it out, perhaps drain battery more? But technology today is crazy and it might not.

I do most of the time, unless I am in a stop and go traffic when the engine kicking on becomes annoying.

i wouldn't say it will drain the battery more, once the car starts, charging from the alternator starts right away so power would be restored in a good amount of time.. maybe we can cancel that out now?
