Four months ago, I had the hybrid batteries replaced on my Gen 2 2008 Prius - Base model with roughly 175K miles on it. Recycled batteries, not new. Sporadically, 4 times since then, I'll get a number of warning lights pop up that suggest something is wrong with the Hybrid charging system. Common conditions for the four events.. 1. It's generally hotter time of day. I live in Houston. 2. I've been driving for a while. Warning lights and Codes On Dash (See attachment) 1. Master warning (triangle with exclamation) 2. Check Engine 3. Brake System Warning (circle with exclamation in parantheses) 4. VSC (Vehicle Stability Control) On Multi-Display (See attachment) 1. Hybrid System Warning (car with exclamation) If I drive long enough, the AC stops cooling. When I stop the car and turn it back on, the brake system warning and VSC lights do NOT come back. A couple days later, all lights are gone. Checked the inverter coolant reservoir to make sure it was OK. It was and topped off to Max. The technician who did the hybrid battery replacement said he could see the coolant swirling in the Inverter reservoir. Had the codes pulled at Autozone. Returned POA93 - Inverter Coolant System (See attachment). Since the lights have been coming on since the battery replacement, suggests something happened during the battery replacement. Could the inverter pump have failed just coincidentally? What does it look like to see coolant swirling in the reservoir with the cap off? When I look with the car running, I don't see any movement. Suggestions for where to go from here? Really grateful for any help!
