Maybe where you live, but not everywhere. If your attached garage stays warm when it's below 0, you either have poor insulation between your garage and house, or it has a heater in it.

 

My garage is part of my house. It’s not a problem. When it was 0 degrees here last winter it didn’t get much below 60 degrees in there. The cars stay safe and like I said half the time if I have windows down I don’t even roll them up when I pull in.

Detached garages are different.

 

I keep saying it, heated garage in the salt belt = early rusty death the heating/cooling cycle is ideal to accelerate corrosion. I won't work on cars that live in these conditions.

 

What if they go to a GOOD carwash with LEGIT undercarriage wash, like every other day?

Surely they exist up there for that exact reason, to help keep rust from taking over?

The amount of rusted cars I see when I go to Rochester is stunning, obviously. My FIL had an old 800 Silverado and finally got rid of it. It was rusted but still okay.

 

Then the problem will be even worse you're driving water into everything. Road salt is not just salt it contains chemicals to make it stick to the road you know what that means. This is easy to see, pressure washing doesn't remove all the salt from undercarriage components it requires mechanical action and no one is going to crawl under their car and scrub every time they go to a car wash. Wheel cleaner neutralizes salt if you spray then scrub.
The only thing that works is products like Fluid Film it is very effective. But it doesn't stop exhaust components from rotting out and whoooo boy do they ever. Some engines even end up with blown head gaskets the salt eats away at the head and block. In this case the engine bay should be washed a few times in winter, actually I recommend this for all cars.
The $ figure loss from road salt must be staggering I really don't understand why it is used. Mandate winter tires and forget the road salt this will end up being far cheaper in the long run. Some locales in Alberta don't use any road salt the difference is drastic. I buy/sell cars from these areas I NEVER buy cars to flip that have seen road salt.

It will be interesting to see how my Y holds up long term, one thing that might give EVs an advantage is the underside is mostly smooth not much is exposed. Of course there is still traditional suspension stuff to be eaten away.

 

There is definitely truth about heated garages not being great when you're talking about activating salt leading to corrosion.

 

Suspension and brakes, rotors are still going to rust. I'm so thankful it doesn't snow or roads don't get iced up here

 

LOL, ok. Did you happen to open the garage door during that time? How long was it below 0? It can stay that low, or lower, here for a few days at a time. If you think an unheated attached garage should stay a comfortable temperature during that time, I don't know what to tell you.

 

No, the LX was parked outside when we had our little blizzard and that's what I drove.

I would never, ever need a separate heater for my garage.

Damn, I'm sorry for all of y'all. That just doesn't exist down here, none of it. Never have to worry about any corrosion or rust.... or rough winters.

The LS was a Knoxville car, the LX was North Carolina vehicle and the Mercedes was out of Chattanooga.

 

Ok, so not at all relatable to the discussion of why some of us prefer to preconditioning our BEV's in the garage at times.

 

It all depends on the structure of your house and the garage and the insulation and climate. My garage is really within my house, it has two finished levels above it, finished basement space behind it and to the left side. Only the door and part of the right side wall are exterior and half that right side wall is underground.

It doesn’t get down into the 0s here but even when it’s as cold as 12, 14 degrees it’s never even in the 50s in there. But, that’s because of the way the garage is integrated into the house.

 

I get why you guys wouldn't need to precondition in your climates. I have no problem agreeing with that. My issue is with comments like this, that come across as condescending.

It has nothing to do with the insulation in my garage. All walls are insulated, probably to a higher R-value than yours, and drywalled along with a fairly new insulated garage door. The ceiling is 9 feet tall and living space extends above it. When you open the door for a few minutes, it very quickly drops the temps. If I need to snow blow my driveway it stays open much longer.

One shouldn't make broad judgements based on their personal situation. Much like BEV's currently aren't viable for everyone. YMMV...

 

Two of my cars are garaged and two are not. I have remote start as well on two, I rarely ever use them. Once in a while. . Cold just doesn’t really faze me. I just don’t like prolonged hot weather, especially too hot at night . I have spent time in a desert region, the cold swing was so cool. I love the fall.




saw another bZ4x today. Hmmm it’s a sign I need to get an electric Toyota 👀

 

Your definition is aligned with this denizen of the frozen tundra.

 

Do you need a Xanax? My GOD the heat in this forum.

All I said was I don't/wouldn't need it in my current situation.

And explained a real-life situation where it would be ideal.

If a garage is attached to the house and your house has adequate insulation you shouldn't have a problem either.

My situation would be ridiculous. Leave my 68 degree house to get in my 70 degree car? I wouldn't fuss with the fancy preconditioning stuff.
