I was at a stop sign, when to accelerate and heard a loud CRACK or popping noise. Car seems to loose power after and when I turn car off and restart it, it sounds rough Idling. Also noticed when I turned the car off and opened the hood sounds like a hissing coming from under the hood. Just bought this car used a month ago馃槱 still under the 10 year 100,000 plus an extended warranty. What could this be!!??

Would be nice to know year, engine, mileage, but unless you purchased it as a CPO vehicle, the second owner warranty only 5 year, 60,000 miles.
Is the check engine light on?
Another member posted about how their intercooler popped open. Maybe just do a quick check to see if yours is still all sealed together?

Guess I'm blind, didn't see the info posted under your ID, but how about the engine size?
