The car started to make very loud engine noises and then the engine completely failed. The car was no longer able to accelerate and lost the ability to go in both forward and reverse. Luckily, my son had just arrived home when the car completely lost power, but it began to have acceleration issues as he was driving home. No warning lights came on until after the car had completely failed. Less than a week prior to the incident, the car had an oil change and inspection by the dealership and no issues of concern were noted. The car was towed to the dealer. The technician said that the oil contained metal shavings, indicated an engine block failure.

Arriving at my childhood home, I followed the driveway to the left to park in front of the garage door. With my foot on the brake and slowly rolling to a stop, the car suddenly accelerated and jolted forward making contact with the garage door and the frame of the garage. This caused damage to the house, garage door and the front of the car. Thankfully there was no other car in the way or a pedestrian! Only the house and car were damaged. This was sudden and there was no warning or prior occurrence to make me aware of the problem. We spoke to the dealer service manager and at first he said he never heard of anything like that. After further conversation he admitted that another car had a similar issue. They kept the car for two weeks and couldn't repeat the issue. We then went on line and found there are several class action lawsuits against Subaru for the same thing - unexpected and sudden forward acceleration! But when contacting Subaru corporate for assistance in resolving this, they claimed they never heard of any class action lawsuits or problems such as this. We need help dealing with Subaru. They are playing with us.

In heavy traffic, we were rolling slowly along, when all of a sudden the engine began revving on its own, against the brake. I quickly moved the shifter into neutral, and the engine revved wildly without my pressing on the accelerator. We couls have easily slammed into the car in front of us had I not moved the selector to neutral.

Flex joint connecting to catalytic convertor. For 3+ years, exhaust from engine coming directly into cab, coughing, nausea, burning eyes/nose/lungs/chest. Foul odor, difficulty breathing. The problem has been reproduced and diagnosed by two independent mechanics. The dealer, when initially requested to inspect expeditiously, couldn't get me out the door fast enough. The component has only been inspected by two independent mechanics. There were no warnings. I would like to add that this specific part has already been subject to Subaru Program Bulletin WUB-87, WUJ-95, and is reported by mechanics as common defective part.

On 9/28/23 I was driving in a 2-lane construction zone with my daughter. While going through the construction zone, my car lost all power and just shut off completely. No warning signs just went completely dead. I almost got rear ended, thankfully the car behind me went to the left of the center, but almost had a head on collision into oncoming traffic. Thankfully, no wrecks were involved. It did eventually start back up and has yet to happen again. However, back in July/August of 2021, I received a recall notice on my vehicle the federal safety agency Campaign #21V587000. When I called to check on the recall it was stated that my vehicle did not have a current recall. I believe this is inaccurate to the fullest. When I bought the vehicle, I took my outback in several times to the dealership with what I thought was transmission and some electrical issues. They could find nothing wrong, how convenient for them, they weren't the ones almost killed because the vehicle would stall at intermittent times during acceleration. I took it in on 1/24/19, 4/26/19, 10/24/19, and 7/27/20. The mileage range was from 1K to 55K, now at 111K my car just has a complete system failure. Honestly, they didn't seem enough to care and treated me like I didn't know what I was talking about. I drove it 7 days a week and they drove it for 15 minutes and said there were no issues. That is not a fair assessment. I would like to resolve this matter before someone gets killed because of a defective issue on Subaru's part that was documented several times. I have the receipts and work orders to support the evidence. I have notified my family of the issues in case something does happen because of the vehicle, and I am, or others are injured or killed in an accident. Like I said, I have all the documentation to support any claim henceforth. I bought a Subaru because of its safety ratings. Now, I'm afraid to have passengers or my grandkids ride with me out of fear for their safety and others.
