Vehicle will shudder and stall when coming to a stop most often in the uphill position, it will also stall when coming to a stop after braking hard. This problem is avoided if you place the car in neutral but that is the only way. Engine idle will drop drastically and the vehicle has a hard time reengaging into drive after coming to a complete stop. I assume it is the cvt transmission or the torque convertor.

Another vehicle stopped directly in front of me, hitting the front of my car with force. Then that car abruptly left the scene. The airbags did not go off and I was severely jolted. Then the car went up in flames. I was in a state of shock and confusion. Left the scene and ran home as my body was in turmoil. I had to use the bathroom immediately. I then called the police. Regarding the accident. The other car has still not been found. Progressive is my insurance. The car was towed to a lot in turnersville, N.J. my insurance company has all the information.

Car shuts off while breaking. Used to happen when stopped but now happens a few times a day when just trying to break. It almost caused an accident a few times. The car shuts off while in drive, lights flash on the dash, I have to put in park and turn the key off. It starts up fine, but happens again and again. It's been going on for about half a year and is getting worse. No one can seem to find any fail codes or anything.

Car stalls when slowing down or braking to stop. No error codes or engine light warning. Car starts right after but stalls again frequently. Checked all fluid levels ok. Happens with hot or cold weather.

On Wednesday, November 19, 2014 my son left for work at his usual time and started the Subaru. Immediately, the engine roared at full throttle, and the vehicle took off down the street, where it jumped the curb and crashed into a tree at 45 mph. Distance traveled was less than 400 feet from where it started. Based on an eyewitness account, it is presumed that the vehicle suffered an unintended acceleration mechanical issue outside of the driver's control. Emergency service personnel arrived within minutes, and he was taken to the major metro-area 833 bed hospital (level 1 trauma center) where he was admitted to critical care. He died peacefully and without pain on Wednesday afternoon, November 26, 2014, at age 37. Subaru of America was notified of this incident on Friday, November 21, 2014; a detailed description, police crash report, and 18 pictures were provided, with a request for them to inspect the totaled vehicle and download available information from the black box recorder/event data recorder. (note: As of today, November 29, 2014 no action has been taken).

The 2010 Subaru Legacy GT has a defect in the sensor that determines weight in the passenger seat. This sensors function is to turn the airbag on or off depending on the amount of weight in the seat. With a 114 pound woman in the passenger seat, the automatic airbag sensor does not signal for the airbag to be ready to deploy and continues to be in the off mode. After taking the vehicle to multiple Subaru dealerships, I was informed that the needed weight to turn the airbags to the on mode was 17 pounds. My 114 pound wife is far more than 17 pounds but the airbag sensor still does not trip to the on mode. I am worried that a passenger will not be protected in a possible crash.
