Did you have the ac recharged in 2018. Current AC systems loose 10% of the chemical every year because the molecule is so small. Once you go below 80% you are risking destroying the pump.
Recharging the AC every 2 years and checking the break fluid quality every 2 years are the only preventative maintenance that you have to do on Tesla’s now. I do not think Tesla is communicating this aggressively enough. There should be a maintenance pop up that only a technician can clear since not doing that is a $5000 mistake.
If you did recharge the system at the 2 year mark then this is worrying for the quality of the ac pump.
If ecopsider5 is talking about R134a, then that's complete BS. I had an 06 Prius that I bought new in Jan 2006 and sold in Feb 2019. It has never had an AC recharge. The AC (has an electric compressor) still works fine. I don't recall any maintenance interval for recharging the AC. If there was, it certainly wasn't anywhere near that frequent.It's R134a i.e. 1,1,1,2-tetrafluoroethane which has been in use since the 1990s when it began to replace R-12. If you lose refrigerant you will notice reduction in cooling capacity long before the compressor is damaged if it is ever damaged.
From checking Priuschat, that generation of Prius (gen 2: 04 to 09) used R134a.
My '13 Leaf (built 5/2013, I bought it used in 2015 and is over 6 years old now) also uses R-134a, per the manual. I've checked the maintenance booklet which ends at 8 years and 120K miles. There's nothing in the schedule about recharging the AC. AC works fine.
jboy: I saw you brought up BMW a few times. That's part of why I don't buy BMWs or German cars. The joke about BMW is "Behold My Wallet" or "Broke My Wallet". Their reliability is spotty and maintenance and repair costs can be very high. Until my most recent purchase (still not German), I've tried to stick to Japanese brands where the model has average or better than average reliability year after year.
Maybe 2 years ago, I finally replaced the lightly seeping engine water pump on my Prius (you could see a bit of coolant crust around the pulley). Had been like this for years. I went to an independent garage.
Someone else at my work had their Audi A3 engine water pump completely fail (most coolant leaking out in short order) at around 30K miles but past warranty due to time. I wish I remember the numbers, but IIRC, the cost for her at an independent garage (cheaper than dealer) was on the order of 3x the cost of what it cost me.
