I had the codes checked at Autozone, and they are p0449, p1516, and p2101. I let the car sit for a few hours, and it started just fine. But every once in a while, and getting more frequent, the car will go into safety mode immediately after starting, if it allows it to start at all. What could be causing this? The car is completely stock.

did you look up the codes, do you know what they mean??
