I was driving on the highway traveling about 70 miles per hour in the mountains of Colorado when my car's accelerator stopped working. I was on a sharp downhill curve when I was no longer able to accelerate my car to keep up with traffic. This was extremely dangerous as I was almost hit by the cars behind me. There was no warning prior to the incident.

My vehicle lost all ability to accelerate while driving on the freeway. I had to coast into the emergency lane, which was a wall of snow in Colorado at this time of year. Blocking traffic in the slow lane, I waited for a tow to my Subaru dealer. They told me that my pedal accelerator assembly had failed. After repairs, I experienced the same problem 2 weeks later. This time they are stating that my electronic throttle body has failed. I have researched carcomplaints.com and see that I am one of over 50 consumers that have experienced this problem.

Three times I have lost all acceleration while in motion, with the car and engine slowing to idle speed even though the accelerator is depressed. This occurred twice on two-lane highways and once in my driveway. In all cases, the car returned to normal after being turned off for a short time and restarted. My mechanic is looking into a possible electronic throttle issue. In searching the internet, I find this is not an uncommon problem with 2006 Outbacks and other Subaru. This is a dangerous condition that could prove deadly if it happens on a busy highway and Subaru should address it.

I recently had P2138.. one time. No throttle response, stopped on a hill on a 2 lane road, on a curve, in big sur.. not good. Rolled backwards down hill after the ones behind had all passed me. Turned off car, waited for 10 minutes, then it fixed itself after a restart. Jiggled the pedal connector and it has been gone for the last 2 weeks while waiting for my mechanic to have room in his schedule to replace my throttle pedal (which has a pedal position sensor), two days from now.

I was driving on the interstate and when I got onto the exit ramp, the vehicle gas pedal stopped working and the check engine light came on along with flashing cruise control light. I coasted into a dealership with hazard lights on at about 10mph. Diagnosis was a faulty accelerator pedal sensor. This could have been very dangerous if I was in heavy traffic or still on the interstate. Car only has 53,000 miles on it.

I was traveling on a 3-lane highway at the posted mileage (60 mph). Simultaneously the check engine light came on and the gas pedal lost all power. The cruise light was also flashing. I tried flooring the gas pedal, but the vehicle continued to lose power and the speed rapidly decreased to less than 20 mph. This happened with absolutely no warning and no time to get off a busy thoroughfare. This occurred at approximately 3:00 pm, so fortunately the traffic was not extremely heavy. I was able to cut across 2 lanes of traffic that was going 60 mph +, exit on an off-ramp, and get to a safe location to call for a tow truck to take the vehicle to dealership for repair. The outcome was code P2138 (accelerator sensor). The sensor was replaced at a cost of $340. I purchased this vehicle new in 2006, and have kept it well maintained at the dealership per their service schedule. However, until this problem occurs, there?S no doubt it would have ever been caught by the dealer to repair. This is extremely dangerous because it could have caused a serious injury to me and other drivers. If it had been at another time, I could have been rear-ended by drivers going the posted speed limit.

Sudden deceleration of vehicle. Check engine light comes on and the car goes limp. Vehicle is restartable after 5 minutes, however the throttle does not work properly afterward and the vehicle will not accelerate normally, thus it drives much slower, and will not go above 60 mph. Problem comes and goes.

Vehicle lost power and control abruptly while driving at freeway speed. This is a serious safety issue. This happened twice over a two week period. Lucky to have avoided rear end collisions both times as I was traveling in the right hand lane. If I had been in middle or left lane there would definitely have been serious multiple vehicle collisions on a densely crowded I5 where people don't leave safe following distances. Took vehicle to independent Subaru shop and found error code P2138= accel. Pedal sensor circuit. Replaced accel pedal sensor for $269.

Driving on the highway, the check engine light came on soon followed by the flashing cruise control light. At the point, the car became no longer responsive to the accelerator. I was forced to pull over because after breaking, I couldn't speed back up. Turning the car off and on again did not solve the problem. When I turned the car on the engine revved at a high speed with the cruise control light still flashing. I eventually had to get the car towed.

The first incident with this car was me putting the transmission into park after stopping at a gas station and the rpms suddenly shot up to 2000. After filling the tank, I tried to start it but it wouldn't turn over. I let it sit for a moment and then tried again and it started with now the "check engine light" on and "cruise" flashing. The lights self-corrected later that day before I could have the code read. The next incident I was in a left hand turn lane with a green arrow. The check engine light and cruise came on and I suddenly lost the use of the gas pedal. It was completely limp. No matter how hard I pressed on it the car just moved along at idle speed, less than 5 mph. I barely made it through the intersection before I lost the green arrow. I pulled over, put it in park, the rpms went to 2000, then I turned it off. Tried starting it again and it wouldn't turn over. Tried it a second time and it fired right up and the gas pedal functioned properly. The check engine light and cruise were on again. I took it to an auto parts store to have the code read and it came up with P2138, an issue with the throttle position sensor. These incidents occurred twice more before I was able to get a proper diagnosis from a mechanic and they occurred anywhere from one to two weeks apart. This is a potentially very dangerous issue with these cars and should be addressed by a recall by Subaru.

Incident initially started in February, went to accelerate after starting car in the am, did not respond, cel and flashing cruise button came on, engine seemed to idle and wouldn't respond to trying to accelerate again. Turned engine off, tried to turn back on, would not start. Repeated process with starting 2-3 times until started again. Cel and flashing cruise remained on for a couple days, took to repair garage and they said that they couldn't find anything wrong on the diagnostic run. This has continued to occur off and on for the last several months. I have taken it to 2 different shops who could never find anything wrong with the car or get it to reproduce when they drove it, and then to dealer 2 weeks ago, they replaced throttle body and did a fuel injector service. Again, this morning, accelerating at 30-40 mph in start/stop traffic, could not accelerate at 30 mph, engine started to rev, pulled over to side, shut off engine, repeated 2 more times, again cel and flashing cruise. These lights are still on but car drove normally. Very frustrated as I cannot get it to reproduce for shop or for dealership because it happens so erratically.

In the 2006 Subaru Outback 3.0 the throttle is controlled electronically. This failed on me while driving at 70 mph down the freeway. The gas peddle stopped responding. I could not accelerate or maintain speed. I had to pull over. After about 1 minute I restarted the car and the throttle started to respond again. My check engine light is now on and the cruise control light is blinking. This is a safety hazard and needs a fix. After reviewing many forums, it doesn't sound like Subaru knows what is causing the issue. But there are some "recommendations".

There have been two incidents so far. One was traveling on the freeway at 65mph when the throttle completely stopped responding. The other incident occurred at much lower speeds when turning a corner and the throttle no longer responded. In both cases the car would not accelerate or maintain speed. Pressing on the accelerator did not have any effect at all. In both cases the car would "coast" along at whatever speed the engine idling would move it - roughly 15 mph.

While driving on interstate highway, vehicle lost engine power. Electric was still on. Gas pedal did not work. Cel and cruise control lights both blinking. Was able to maintain 15 mph on flat road, and barley any speed on incline. Got off highway near home and shut of engine. Waited and tried to start back up. 30 seconds of cranking, and nothing. Waited another minute and it started. Got home and pulled a P2138 code. Pulled wiring harness off gas pedal and reseated it. Reset the cel and everything has been fine since. Scary situation, especially at 65mph during thanksgiving eve rush-hour.

I was driving when the accelerator pedal stopped responding. I couldn't accelerate or maintain speed. The check engine light was now on and the cruise control light was flashing. I pulled over and the idle was at 2,000 rpms and the accelerator pedal was still not responding. I turned off the engine for about 5 minutes. When I turned it back on, the accelerator was working but the check engine light was on and the cruise control light was flashing.

My wife was driving the vehicle when the check engine light came on. The cruise light started flashing. The gas pedal was non functioning. She was able to cost to a safe place. When I arrived the car was running. The gas pedal was unresponsive. I shut the car off and took her to work. An hour later I returned to the car and tried to start it. It took several seconds to start, but did. The gas pedal worked. The check engine light was on steady and the cruise control was flashing. I was able to get the car home. Today 10/20/12 the car has no symptoms. This could have been very scary as my wife was driving on the busiest street in Montana during the morning commute.
