How many vehicles are using R-1234yf as a refrigerant? Can one convert a car with R-134a to R-1244yf?
R-1234yf

F*** r1234yf. The process when using a machine is so unbearably longer than when using a 134a machine.
But to answer your question, I'm aware of merc, ford and Chrysler using 1234yf. not sure with other manufacturers. As far as conversion, I've read about people just replacing the refrigerant with 134a, but not with such good results.

Toyota is using it as well.
Quite a few mfgs. are using it now. Here is an interesting discussion from a while back, R1234yf which might be of some help. I read of conversions to R134, some good, some not so good. I'd a$$ume those converting probably were low on a charge, might have had leaks, and did a hack job repair and blamed the conversion. That would be hard to say though. My Rubicon is a 2016 and still blowing ice cold w/o touching the system.
All cars since 2016 (and some 2015’s) use R1234yf.
Wrong.
Both of my Ram trucks are R1234yf systems. And, both systems have been to the dealer to have the AC system repaired because they were blowing warm air. Well, not “were” in the case of the 2015.. it’s blowing warm now.
The compressor clutch isn’t coming on, so I suspect that the refrigerant leaked out again. It did that late last Summer, and it probably did it again.
I like my trucks.. they are otherwise reliable but this stuff with the AC, and that I can’t work on it due to the new fangled enviro-hugging stuff is something that gives a guy pause… but any newer truck is probably going to have this stuff in it, so…

R-1234yf seems like a step backwards in an environmental sense. Pretty much every manufacturer has issues with these systems leaking.
Yep. We were always getting calls for r1234.
I can't think of a good reason to switch to the new stuff. They haven't legislated R134a out of existence yet.
Beta testing.
This is absolutely not true. My 2018 Mazda 3 is r134a along with my mom's 2020 mazda CX5. I have not checked my wife's toyota however.
My 2018 Elantra Sport is R134a
I read automakers were doing it for CAFE credits.
Pretty sure my 2020 CX-5 uses r134a.
Its better for global warming. The old R12 had an index of 10,000. R134a was 1400 and r1234yf is 5. With lower being better. Apparently the worst offenders for HFCs are grocery stores.
Pretty sure the three 2019 tractors at work are R-134.
I'm not a huge fan of R-1234yf, but saying it's a "step backwards in an environmental sense" is just plain wrong. When R134a replaced R12 it solved the issue of depleting the ozone layer but R134a still has a very high global warming potential (GWP) of 1,430 which means that one pound of R134a released into the atmosphere causes the same amount of global warming as 1,430 pounds of CO2 released into the atmosphere. R1234yf has a GWP of just 4, so just 0.28% of R134a's GWP of 1,430. So even if your R1234yf car leaked all it's refrigerant say 100 or 200 times it would still be much less harmful than leaking the same amount of R134a just once.
My last R134a was my 2015 Sonata.
My 2017 Continental, 2017 Cadenza, 2018 Sonata, and 2018 Regal all use R1234yf. When I first started using R1234yf, I thought it would not be as good as the former R134a or even the R12.
I WAS WRONG. Every bit as hood. Air comes out of vents between 40F and 44F. Depending on the humidity. With inside set to Automatic, at 72F, the temp at vents usually comes out at 42F.
Back around 2015, the EU considered R1234yf a fire hazard.
European manufacturers (Mercedes) not allowed to use it for their domestic cars, but somehow, the EU rented and allowed its use.
