I was driving with my son (9) during the evening of 12/16/14 on side roads looking at christmas lights. I was going 15-20 mph. Night was dry and clear. Suddenly, the check engine light came on steady, cruise control light began flashing and I had absolutely no acceleration! I pulled over and put the car in "park". engine revved between 2000-3000 even though I was not pressing anything, just idling in P. turned car off for a min, back on, dash lights still on - ce & cc. Still had no control over the gas pedal but when taken out of P, car got itself up to 15 mph somehow. We were very close to home so coasted home and into the driveway. When shifted to P at home, engine revved again. Next morning I drove it to school, ce & cc light still on but car drove ok. When I drove it again, dash lights were off and it drove fine. Same exact issue happened again on 12/23/14, again at a low speed on a side road, thankfully. Error code on the car is P2138 - throttle position sensor. There is no warning before this happens, car is fine and then suddenly it is not. From what I see online, this has been a common occurrence lately with this car. I am terrified that it will happen while I am in traffic or on the highway and cause a serious accident! please investigate this with Subaru, I see that a lot of people have trouble getting it resolved and I don't have the time or money to pay for something that appears to be a common Subaru defect. Thank you for your time and attention to this serious issue!

The vehicle stopped responding to throttle pedal input, resulting in having to pull off the road, across lanes of traffic. Engine light comes on and cruise control light flashes. After restarting 3 times the lights go away. Dealer couldn't replicate so would not cover under warranty. This has happened on several occasions since, usually only in summer. Code is P2138 and appears to be a consistent problem with Subaru vehicles.
