The contact owns a 2010 Subaru Legacy. The contact stated while driving at 50 MPH, the emergency brake warning light, traction control, oil pressure warning light, and the cruise control warning light illuminated. The contact veered to the side of the road. The vehicle was towed to the contact's residence. The vehicle was then towed to an unknown dealer where it was diagnosed that the transmission valve body had failed. The vehicle was repaired; however, the failure reoccurred a week later. The vehicle was taken back to the dealer where it was diagnosed with an unknown electrical failure. The vehicle was repaired; however, the failure reoccurred less than a week later. The vehicle was taken back to the same dealer who advised the contact to turn off the vehicle, disconnect the battery for 5 minutes, and to then restart the vehicle. The contact followed the instructions however, the failure persisted and the check engine warning light illuminated. The vehicle was taken to an independent mechanic where the gas cap was replaced; however, the failure reoccurred. The vehicle was not repaired. The manufacturer was notified of the failure but did not provide any assistance. The failure mileage was approximately 115,000.

When braking and coming to a stop the car shutters and stalls. In order to avoid it, you must put it into neutral or else it will stall and you will have to restart. This is dangerous and a very essential function of the car and needs to be replaced asap. It does this more frequently when coming to an abrupt stop. There can also be lights that sometimes blink - the cruise control light, brake light flashing, and stability control lights. This has been occurring for many years and i have tried to get it replaced and fixed but it was unknown what would fix this issue exactly so it was just money wasted.

My sister and I have the same exact car just one year apart and they both stall when coming to a stop even though the car is an automatic. The brake light blinks, the cruise control light blinks and is unable to be used, the traction control light stays on, and the check engine light comes on. It has been like this for several years now and ive tried to troubleshoot many things to fix it, but nothing has worked. The lights stay on constantly making it unable for me to use my cruise control and the car to stall when coming to a stop at any speed. I also know several others with the same model that have had this issue and also see videos of this happening to other people on youtube and them being unsure of the problem to fix it.

While turning into a parking lot, the check engine light, emergency brake light, the cruise control light and the stability control light all came on and started blinking. Parked the car and shut off the engine. Let set for an hour. Started again. Ran it home and all lights previously indicated stayed on doing the same thing. Car ran fine though in all instances.

There was a recall with this model and year and they told me my car wasn't included in the recall when its doing exactly what the recall was for. I have no horn, cruise control, no radio controls and I don,t know if the air bag works. This car is dangerous to drive and subaru refuses to repair I was told it would be $200. Plus just to diagnose it when they already know what it is. Any help would be appreciated.

I had entered a parking space, and was slowing to come to the end of said parking space. The car rapidly accelerated, and I could not stop it with the brake. I hit the concrete at the end of the space at full speed, which stopped the car. I noticed that the impact had slipped the gear into neutral. When I turned the car back on, it registered that it was in cruise control. I have never used cruise control on any this or any other vehicle. I have bruising from the seat belt, and neck pain from the impact. The vehicle is not drivable due to damage to the front end, and a rumbling noise in the engine with poor response when accelerating.
