Car would not accelerate upon entering the highway after pushing on the gas pedal the car wouldn't do anything. I was able to get off to the side and missed being hit from behind from on coming traffic...I notice check engine light and flashing cruse control light... second time some weeks later it did the same thing this is very dangerous because you never know when this will happen.

While driving, the check engine light comes on and there is no power to the gas pedal. The car is unable to accelerate or maintain speed and the driver needs to avoid potential collisions by pulling over on the road or freeway.

Travel position sensor fails when driving causing driver to loose control of the vehicle. The accelerator stops responding, the car goes into fail safe mode ignores all inputs from driver. The car may coast at about 15mph. This could happen when making a left turn or on the highway at high speeds.

The vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 80,000.

One morning after starting my car I noticed the check engine light was on. As I decided to drive the car down to a local mechanic, I noticed that I had no acceleration power. The car was on, engine was running, but whenever I pushed the gas pedal nothing happened. The car would idle high and coast when put in drive or reverse, but would not accelerate as I pushed the pedal. There have been numerous counts of this happening to people across the country. Luckily I wasn't on the freeway when this happened.

While driving the check engine light suddenly came on and the gas pedal stopped being responsive. Luckily I was able to get to the side of the road and put the vehicle in park. When in park the engine revved to about 2.5K RPM and stayed there. I shut off the vehicle and restarted it and it stayed at that level. After several more tries it eventually started up and ran fine. The check engine light code is P2138 for the throttle position sensor.

I experienced two issues with the electronic throttle position sensor in my 2006 Subaru Legacy. The first time I was traveling at approx. 35 mph and the RPM's began increasing rapidly. I was in traffic and unable to pull off to the side safely when the engine completely stalled. I sat there thinking that the motor was going to blow up if I attempted to start it again. I called my mechanic and he thought that it could be the throttle position sensor, as he has replaced many of them on Subaru. I was able to start the car and move off to the side of the road to make sure that it was not going to do it again. The car was then taken to the mechanic where he cleaned the sensor and said if I have a problem again then I should replace it. Fast forward 4 months later and I experienced the same problem on a busy street where the car lost power and completely shut down after rpms skyrocketed and I was left with no control. Upon start up, the check engine light came on, obviously triggering a code that says the car is a death trap with a really poorly designed throttle. I plan to have the part replaced immediately, but this could be a serious safety issue for someone not in a position to move to the side of the road, as it just happens randomly with no warning signs.

I was driving about 40 mph when I realized that I had no control of the pedal/gas. When I looked at the dash board the check engine light was on and the cruise control light was flashing. I had to pull over and when I put the car in park the vehicle revved high. It took about 15 minutes before the car restarted. I was able to drive home. The diagnostic machine indicated that it was the throttle pedal position sensor.code P2138. The throttle body was replaced. I am still having the same issues.

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!

I was traveling about 20mph during rush hour traffic. My vehicle lost it's throttle capabilities. This was very dangerous as I could only change lanes at idle speeds. I was nearly rear ended and side swiped. From what I can tell this has been a problem with several years of Legacy/outback models.

My 2006 Subaru outback ll bean has been cutting out on me while driving. One incident was on the highway at high speed. The gas pedal went limp and I had to navigate over 2 lanes of traffic to get to the shoulder. Gas pedal was completely unresponsive. Check engine light came on and the cruise control light began flashing. Every time this has happened it was either raining or snowing outside. Took the outback into the dealer and was told they weren't sure what the cause was because they have never seen it before. They suggested replacing the gas pedal assembly, but they were not certain. The same situation happened once when I turned on the cruise control.

While crossing a four-lane road, the accelerator pedal went limp and caused the engine to become unresponsive. The car would not accelerate and barely made it across the lanes of traffic to the median safely. The check engine light illuminated and when placed into park, the engine revved to approximately 2500rpm without my foot being on the pedal. I turned the engine off, and restarted it only to have it rev again on its own to 2500rpm. It took 5-6 attempts to restart it before the engine idled appropriately and the accelerator became responsive again. The check engine light remained on and obd code P2318 was returned when I plugged in a scanner to the port. This is not the first time this event has occurred; it has been random and sporadic for about 8 months now, sometimes occurring as often as 3-4 times per week to going 2 months in between episodes. Speed does not seem to be a factor, it's happened at both freeway and parking lot speeds, in all kinds of weather and at various temperatures, with the cruise control on and with the cruise control off.

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.
