Surging or inability to hold CC can point to throttle body starting to fail. Do you have any diagnostic codes or pending codes?
On ACC - recharge can be relevant. When the recharge was done, was the system evacuated and then refilled by weight with the correct amount of refrigerant (825 or 875 grams, depending on sticker under hood), or was this a top-up with cans? It can make a difference because the variable displacement compressors are very sensitive to even slight over and under charges, and can behave unpredictably.
