The accelerator pedal position sensor is faulty. It is prone to wear in these vehicles based on my research. This caused my car to go into limp-mode on the highway, rapidly cutting my speed in half. The accelerator provides no response until vehicle was restarted. The ECU put out the code P2138 for loss of voltage in throttle system.

OBD Code P2138 (Throttle/ Pedal Position Sensor/ Switch D / E voltage correlation). This code pops up intermittently resulting in the car going into "limp mode". Truly dangerous, if this occurs when traveling at speed in traffic or when pulling away from a stop light. It is hard to pin down; but, it generally happens with high humidity or When you start the car after a cool night when there has been a lot of condensation that has formed on the car. A check of Subaru forums shows that this is a prevalent and / or recurring problem with many Subaru models. (I have also found mention of similar problems with other manufactures.) Dealers and mechanics have confirmed this problem with other Subaru makes. There is no advance warning of this malfunction until after it occurs. Once it occurs the car goes into "limp mode", the check engine light flashes and the cruise control light flashes.

2006 subaru outback head gaskets went bad at about 35,000 miles.had to replace those called subaru and they help me get those replaced. Thought all was well soon after, the electrical system including the air conditioner and the heater .then I was told that the airbags were defaulted and to bring it into replace them which I did. The final straw is that they called me again two weeks ago to bring the rigging to replace that same airbag again. I asked them why they gave me a car that wasn't safe. The wheel bearings also wore out very early around 50 miles. This car has been so expensive. And now they informed me that there was a second recall on the airbag. So I bring it in for the second time realizing that now in 2021 this car has not been safe the whole time I've been driving it with my family my daughter learned how to drive in this car and so did my son. As they were repairing the faulty airbag they cracked the dashboard and then informed me that it would be $300 to fix it because it had a tiny crack in it. Please note that they were the ones that took the dashboard off in the first place. Super rude! I called subaru of america and they decided to reimburse me for the dashboard. They were talking about gluing it back together last I heard I'm very much hoping this is not the case my daughter ensures me that it isn't but we'll see. Also he informed me that my head gaskets were leaking again. The mechanic said that this is common once you've had your gaskets replaced. This makes no sense to me. My car has about 160,000 miles on it and it seems like it's already played out and not safe. What a joke. I'll never buy a subaru again.this has been the worst car and apparently the most unsafe car I've ever owned. Note:this car was consistently unsafe while driving for the last 15 years. I bought it because it had a five star rating for safety what a joke!

Tl* the contact owns a 2006 subaru outback. The contact stated that while driving at various speeds with the accelerator pedal depressed, the vehicle stalled. Several warning lights were then illuminated after the vehicle stalled. The battery terminals were disconnected and then reconnected and the vehicle performed as intended. The vehicle was taken to an independent mechanic who was unable to duplicate the failure. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 160,000. The VIN was not available.

Vehicle developed issue error code p2138, throttle sensor on gas pedal desynchronizes causing vehicle to go into emergency safety mode where power is lost, goes into a high idle, and vehicle must be parked and restarted multiple times before powertrain reactivates. Caused by faulty design of potentiometer on throttle pedal that wears a bare spot. Replacement of throttle (gas pedal) required to resolve issue, which will eventually start occurring again due to poor design. Has occurred when pedal isn't being used (cruise control only), as well as during normal driving at all different speeds.

I was driving my 2006 subaru outback at around 40 MPH, going straight on a busy road. Without warning, the accelerator stopped functioning and the vehicle slowed down abruptly. It apparently entered a "safe" mode, with a maximum speed of about 10 MPH regardless of how much pressure I applied to the accelerator. The "check engine" warning light was illuminated, and the cruise control light began flashing. I pulled into a parking lot and turned off the ignition. When I re-started the car, the warning lights remained illuminated, but the accelerator functioned normally again and I was able to return home. The vehicle's engine management computer provided an error code p2138, throttle position sensor/switch voltage correlation. This appears to be a common problem with subaru vehicles from around this model year. It has the potential to be an extremely dangerous situation when the throttle suddenly stops working and the car slows to a crawl abruptly. My 17-year-old daughter is the main driver of this vehicle. If the error were to occur on the highway, it could cause a serious accident. There is no reason that the computer needs to put the vehicle in "safe" mode after sensing an electrical abnormality in the throttle wiring. I would like to request a recall to correct this extremely hazardous safety defect.

The battery was replaced, but the failure recurred. The manufacturer was not contacted. The failure mileage was 95,000.

While driving car check engine light will come on and cruise control light will flash. Car goes into limp mode and the accelerator will not longer respond dropping the cars speed drastically. This can happen on any road, at any speed, and any weather condition. Temporary fix is to stop and cycle the cars power three or four times. More permanent fix is to replace the pedal assembly-accelerator at a cost of $199. Happened a few dozen times before I finally got the pedal assembly replaced. Issued started early 2016, and replaced the assembly in 2018.
