w/out knowing the definition of the codes, i'd gamble on the fuel cap throwing it.Purchased on Wed, 3.6 limited, now with 250 miles. Car sat in driveway last night. This am, turned on, flashing brake light, VDC, eyesight, lane warning off, cEL on... Scanned codes p0700, p1843 pop up. Drove it about 10 miles. Turned off and sat for about 5 mins. Turned back on, CEL off, brake light no longer flashing but still stored codes in system????? Any ideas. Having it towed to dealer right now.
