Default 2014 Cherokee one of the first to use 1234yf refrigerant

To help kick off this section I figured I would add this bit of interesting information for any potential buyers or owners.

The new Cherokee is one of the first dozen or so cars to start using a new refrigerant called "1234yf" instead of the common R134A. The reason for doing this is that "vehicles that use the new refrigerant, like the Cherokee, qualify for tradable credits from the EPA, helping them (Chrysler) comply with new fuel economy and greenhouse gas standards that will double to the equivalent of 54.5 mpg by 2025"

The main downside to this new system is the cost: "While the old refrigerant costs about $5 per pound in bulk, the new one costs about 10 times as much -- and it requires new equipment at dealerships and repair shops that service the air conditioners."



So far the following newer vehicles will arrive at dealerships with the new 1234yf but many more are to follow:

Cadillac XTS (2013, 2014)

Chevrolet Spark EV (2014)

Chrysler 300 (2014)

Dodge Challenger (2014)

Dodge Charger (2014)

Honda Fit EV (2013, 2014)

Jeep Cherokee (2014)

Range Rover (2014)

Range Rover Sport (2014)

So when the owners of the listed vehicles go in for an A/C recharge, they're gonna flip their wigs huh?''

Well maybe not the Range Rover peeps cause they're used to highway robbery at their dealership.

Will be interesting to see how automakers come up with 54 mpg vehicles in just 10 years, even with all the high tech of todays cars they don't get much better mileage than vehicles from the 80's with comparable weight and engine sizes.

From an owner's POV this isn't a huge deal... an AC system in a car typically holds only 2-3 pounds... Freon will last forever unless there's a leak, so it's not like a common maintenance item. I asked my dad what he thought about this (he owns an AC business) and he just shrugged.

Through r1234yf is potentially much more dangerous if it does leak. r1234yf is flammable (though they claim it is unlikely to ignite under "normal circumstances" in an automotive application) and releases highly toxic gases (hydrogen-fluorine) when it burns. While it might not be an issue in a "normal-leak" I would worry how it would react in an accident where electrical arcing or a fuel fire exists.

Interesting. I can't see them using it if it posed a legitimate threat, however... They wouldn't just produce something that's going to blow up and poison people when it gets into an accident, would they? Danger of lawsuits, etc.

Edit: after watching that video I'm a little bit... conflicted.

At the very least it will jack up the price of new cars a little more.

Mercedes Benz is flat out refusing to use it in their new cars in Europe, even though it's law there (they're fighting the law in court). They seem to think the dangers outweigh the benefits...

I would say the poison thing is not that big of a deal, old refrigerants like r-12 or any cfc could produce phosgene if burned or exposed to extreme heat, but I don't get why dealers would need a me machine just to handle the stuff.
Heck the new r22 replacer mo99 has a little butane in it and no one my work has blown up yet.

Fosgene gas sucks!!!! For the younger generations who don't know what fosgene is, Google Mustard Gas.

HFO-1234yf has been shown to have four times less of an impact on global warming than CO2.

Global warming has been shown to make a lot of people rich as hell as they scam the public with their nonsense.

Is it even called global warming anymore? I thought they just broadened the term to 'climate change' so any time something bad happens they can blame it on pollution, force new regulations and make the folks who are connected even richer.

I couldn't agree more.

The hell they wouldn't. It's cheaper at this point to let the cards fall where they may and declare ignorance.

What about electric cars and hybrids that get into collisions? Frickin HazMat **** right there. Do they care? No.
