Cruise Control problems of the 2006 Subaru Legacy

While driving in traffic all of a sudden the gas pedal stops working, the check engine light illuminates the cruise control light illuminates but the pedal has no effect on the engine the car slows very quickly and comes close to causing an accident. I have checked forums on the web and found where many others have had same issues. The forum is Subaruoutback. Org please check this sight the code is p2138 any help will be appreciated.

The contact owns a 2006 Subaru Legacy. While driving various speeds, the vehicle lost acceleration and the check engine and cruise control warning indicators illuminated. The contact coasted to the side of the road. The vehicle was towed to the contact's residence. The vehicle was taken to the dealer, but the technician could not find a code to identify the failure. The vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 80,000.

Tl-the contact owns a 2006 Subaru Legacy. The contact stated that the vehicle would not accelerate when the gas pedal was depressed.

The failure mileage was 140,000. Ad.

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 occurance 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!.

Tapped brake pedal to disable cruise control. No throttle control when resuming manual speed control. Coasted to a stop through multiple lanes of freeway traffic. Engine kept running possibly at raise idle speed when stopped. No loss of power steering or brakes. Turned key off. Restarted after maybe less than a minute. Throttle control resumed. Check engine light was on. Drove to multiple locations to get codes read. After 2 or 3 restarts check engine light went out. Found a shop to read codes. Code p2138 in memory. Have removed throttle pedal assembly and tested position sensor resistance values. Some readings may appear to be slightly out of range indicated in service manual. Intend to recheck readings and possibly replace pedal assembly. May also check harness resistance and/or consult dealer. Mileage reported is approximate.

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.

Tl- the contact owns a 2006 Subaru Legacy. The contact stated that while driving approximately 25 mph, the cruise control and check engine warning lights illuminated. The vehicle would not accelerate and engaged into limp mode. The contact shut the engine off and after restarting the vehicle, the contact was able to drive without failure however, the warning lights continued to illuminate. The failure recurred three times intermittently. The vehicle was taken to the dealer for diagnostic testing. The technician was unable to diagnose the failure. The vehicle was not repaired. The approximate failure mileage was 72,300. Kmj.

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.

: the contact stated while driving various speeds downhill with the cruise control activated, the vehicle accelerated without warning. The vehicle was inspected by a dealer who determined that was the way the cruise control was designed to function. The dealer instructed the contact to disengage the cruise control while descending downhill. The manufacturer was alerted. Updated 9/13/2006 - the cruise control was set at 58 mph but while driving downhill the vehicle accelerated to 77 mph.
