My cooling fan was spinning at full speed after I shut off the car. I have to push twice the ignition to "on" and then off again to turn off the fan. This is the 3rd time it happened to me in the 3 months of ownership.

Is this due to some sort of temperature sensor? Somehow to me this is not normal.
Anyone else have the problem?

Not a problem, mine does it too when its really hot out. I'm sure its just the car doing its thing.

But wouldn't this drain the battery out pretty fast? I mean the car is off at the time already.

No, it barely takes anything to spin those fans, and they won't spin for long. Just until the block is within what the ECU deems to be within the proper temperature window.

Since I'm in AZ and it's been over 100 degree lately, mine does it all the time. Pretty normal as stated.

It is very normal and shutting it off by cycling the ignition probably isn't a good idea. Remember especially when running turbo cars, you need to give them cool off idle time and when you take it off, let that fan keep running. Heating issues can really take some life out of that turbo and other components.

Roger, it's the first car that did that for me. T Hanks fellas

Are these cars electric, or mechanical water pump? Would the coolant still be pumped for the time the fans are on, further cooling the engine after shut off if it is electric waterpump?

A good habit to get into, I always drive much more conservatively when I'm about 1KM from home, use a higher gear so the RPM's are lower, and more air is flowing through the cooling system. Then usually 20-30ish seconds of parked idle. No idea if it has any impact, but just something I've pretty much always done on every vehicle.

Side note: almost at 10,000KM...

I can't figure out why Hyundai doesn't have a "turbo timer" included in the Bluelink app. It already has control for starting/stopping.

Turbo timers are only needed for cars that do not have a liquid cooled turbo, which in reality is nothing released in recent memory.

Coolant flows through the hot turbo housing after the car is shut off by "thermal siphoning". Basically, hot coolant rises, and pulls cooler coolant through the housing.

Check this whitepaper by Garrett. Same principal for all water cooled turbos.

By the way, my first car was a 1986 Mazda 626 GT turbo, an oil cooled turbo, no intercooler.

I beat the **** out of that car and never let it idle to cool the turbo down. It was still running STRONG when I sold it with 144,000 miles on it.

This is 30 year old turbo technology we're talking about, beaten on by a 16 year old, and it was fine, even with 144,000 miles on it.

Not too worried about the water cooled turbos in our 2017 models.

Mid-80's to 90's sure was a great time for the Japanese, now look what we have in terms of build quality. Although that fun era is returning in a new way I fear reliability and dependability will be taking a dive :(
