Hi! I have a 2015 wrx w/ 30000 miles on it. My CE, hill assist, abs and traction control light all came on as well as a flashing cruise control symbol. My car would drop to almost a stall at stop, mpg dropped severely in a week since the lights came on and the car felt like it was working extra hard at 2-3k rpm. I took it to Subaru and they said it was a faulty AF sensor so I had them put in a new one. It ran fine for a day but now all the same lights have came back on and my mpg has once again dropped severely. Anybody have any ideas?! Thanks! Btw first post and just joined the wrx club!
