My wife and I just bought the liberty with 108k on it. i filled it up when running pretty low (Gas warning light was on). the next morning it didn't want to start. I got it started by giving it the accelerator a few times for a few starts. when it did there was some white smoke that came out of the exhaust. later that day my wife took it to lunch and the engine light came on. it was evap code p0455. i had a mechanic clear it and had no problems. last night i put some dry gas in it and filled back up. it again was pretty low (Gas warning light was on) had no issues again until this morning with the same wouldn't start routine. same smoke. got it started and my wife is off to work. anyone comments on possible issues would be great.
