Your description of cooling loss for 3-5 minutes is consistent with evaporator freeze protection. Condenser fans should move a lot of air and make some noise so check air flow since the error codes indicate overheating and the controller will shutdown the compressor to protect it (this would also yield the symptoms you have). I installed a temporary resistor to keep the heater from turning on in my 2011 and could still see at least 3 kW compressor draw under high ambient conditions so your 2 kW load is reasonable. The heater on while using A/C happens at moderate temperatures so it probably was not involved in your loss of cooling condition (although I highly recommend the modification and would have purchased the plug-and-play kit if my 2011 had not been totaled).
The A/C systems in both 2011 and 2015 work great in high ambient temperatures so your symptoms are not normal.
Ordered a new filter - appears easy to replace
Both fans operate quietly and pull lots of air
The compressor is little noisy, in fact I thought it was the inverter humming until checking more closely (due to this issue)
Good to know that the A/C unit itself will pull up to 3 kW. Don't know that I've seen that high, but when on full blow/cool, it still cools the cabin down quickly
Going to finally order the kit - just makes sense in Houston as the heated seats/steering wheel work 99% of the time
Thanks for the info.
