Driving home today in 90+degree stop and go traffic. A mile from home the CEL comes on along with Service Electronic throttle. I get home and pull codes U1008, P2BC1, P008A, P062A and P0236. I don't drive the car often and just assumed (like usual) that it was battery related. I pop the hood to hook up the tender and notice my coolant tanks are over the max lines. I did just get the car back from the shop for an AC issue 3 weeks ago but they didn't say anything about filling (or overfilling) the coolant. Is this the cause or is this a symptom? Is the car safe to drive? Do I need to suck out coolant?
