Car loss power and went into limp mode with a solid check engine light and blinking cruise on the dash. The rpm jumped high with out the gas pedal being pushed down. Vehicle was in motion driving at 25 mph before the aforementioned happened.

3 Vehicle Speed Control problem

Failure Date: 09/19/2017

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.

4 Vehicle Speed Control problem

Failure Date: 03/23/2017

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.

5 Vehicle Speed Control problem

Failure Date: 03/11/2017

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.

6 Vehicle Speed Control problem

Failure Date: 10/30/2016

Driving at 55 mph vehicle accelerator became unresponsive. Check engine light came on as well as cruise and sport lights. There was no power at the pedal. I had to coast to a stop in traffic lane. Engine surged up and down in rpm's. Shut key car off. After a couple minutes, car started and driving was resumed like nothing happened. Warning lights remained on in dash.

7 Vehicle Speed Control problem

Failure Date: 09/15/2016

Ive had a on going issue with my tps I press the gas and nothing happens I've almost gotten into multiple accidents from it happening in the middle of a road/intersection even almost got arrested due to it happening at an air port.

8 Vehicle Speed Control problem

Failure Date: 04/05/2016

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.

9 Vehicle Speed Control problem

Failure Date: 03/08/2016

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.

10 Vehicle Speed Control problem

Failure Date: 07/11/2015

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 Subarus. 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.

11 Vehicle Speed Control problem

Failure Date: 03/11/2014

The contact owns a 2006 Subaru Legacy. The contact stated that the vehicle abnormally accelerated while the brakes were engaged at a complete stop. The contact was able to restart the vehicle with the illumination of the check engine warning light. The vehicle was taken into a local dealer where the technician diagnosed that the throttle position sensor had failed. The manufacturer was not made aware of the failure. The failure mileage was 129,000 and the current mileage was 129,000.

12 Vehicle Speed Control problem

Failure Date: 06/07/2013

Driving at 35mph I pressed the gas pedal to accelerate to go up a hill and nothing happened. Steering became very tight. Had to coast to the side of the road. Shut car off and waited then turned back on. Has happened 1 other time since first incident, with no warning or indication. Researched online to find this is a common problem with my vehicle's throttle/pedal position switch. Had I been on a more busy street or on a highway when this occured, numerous vehicles may have been effected.

13 Vehicle Speed Control problem

Failure Date: 05/09/2013

Tl-the contact owns a 2006 Subaru Legacy. The contact stated that while driving at various speeds the vehicle will lose acceleration. The contact was able to restart the vehicle with the illumination of the check engine warning light. The vehicle was taken into a local dealer where the technician diagnosed that the throttle position sensor had failed. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was 60,000 and the current mileage was 90,000.

14 Vehicle Speed Control problem

Failure Date: 04/16/2013

I was driving in the left lane of the highway during rush hour when the accelerator stopped responding. I would push the gas pedal and nothing would happen. The engine seemed to be running nominally (idling, since the accelerator wasn't working). No unusual sounds, no jerking, nothing. Then the check engine light came on. I managed to get across the lanes of traffic coasting and rolled slowly into a gas station. I turned the car off and turned it back on and everything worked fine again. I finished driving to work without incident. I went after work and had the check engine code read. It was a stored code (no longer actively faulted) of p2138 which is a throttle position sensor error. I've been reading online and this appears to be very common and an ongoing problem for lots of people. It is incredibly dangerous to not be able to control your car randomly in the middle of the road. Hopefully you can help make Subaru fix this safety issue.
