For 2010 does it just keep letting you drive in EV? I saw leaks around the condenser and the in/out hoses on the compressor have cracks in the rubber. So I think I need to order those hoses too.

This limits are determined by battery temperature. Below 90°F is pretty much no limits. Between 90-100°F is progressively decreased battery power. Above 100°F, the battery is severely restricted and does little more than start the engine.

I would suspect that the system shuts down if the battery temperature exceeds a certain limit. I don't know for sure. But driving at high temperatures like in Arizona would inevitably reduce the battery lifespan. Just saw your message today so sorry for the late reply.

Why don't you just get the system checked out by a reputable A/C shop in your area instead of bothering us with your garbage? It's not a complicated system.

He needs a full gauge set. Having the single isn't enough. Much cheaper than an A/C guy. High side will tell you if the compressor is compressing or not. This data isn't in the computer. $30 when I got mine. I'm still getting by on another fill. Added less than 1/2 a can. Turns out my 4wd wasn't leaking, it's the passenger CV axle seal. 4wd pumped out what I put in last year.

R134A is a greenhouse gas. Be responsible and fix the **** leak.
