Owner reports
Selected complaints filed with NHTSA by 2012 Subaru Impreza owners, lightly cleaned up (personal details are redacted by NHTSA).
The contact owns a 2012 Subaru Impreza. The contact stated that while driving approximately 30-40 MPH, the vehicle lost power steering functionality and was driven with manual steering. The failure occurred while driving at various speeds. The contact stated that approximately four days after the first failure, the steering wheel failed to move. Additionally, the vehicle was losing oil and one quart of oil had to be added every month. The contact stated that the power steering, ABS, TPMS, transmission automatic transmission fluid (ATF), and 4-WD failure warning lights were illuminated. The passenger occupant sensor chimed for the passenger to secure the seat belt consistently even though the occupant was seated with the seat belt buckled securely. The contact who is a certified mechanic had replaced the rack and pinion. …
The AC unit suddenly shutoff and there was a burning smell while I was driving. It turns out that the connector on the back of the climate control unit had either drawn too much current, or the resistance was too high, and the connector had started burning. Fortunately, the melted plastic interrupted the electrical connection, and the fire had went out on its own. It looks like this is not an isolated incident, and several others have dealt with similar when looking online.
Brake Lamp Switch failed in 2018 - we diagnosed the issue, based partly on information from other Subaru owners who had the same problem, and replaced the switch. Since that time, the brake lights have worked fine. We reported this in a letter to Subaru after their recall for the brake lamp switch replacement in 2019. They refused to pay for the part as we no longer have the receipt (not having a crystal ball, we couldn't see any reason to keep it for more than a year in 2018). We did not contest this - in fact, I had merely asked, in my letter, that they note that the part had already failed and been repaired in their records - however, they continue to flag the car as an open safety recall and insist that we bring the car in to replace a switch that no longer needs replacing. …
The Airbag warning light has been lit within the dashboard. The front passenger seat airbag is faulty and is not able to correctly sense when a passenger is within the seat or not, which disables the airbags. This can be deadly to the passenger if in an accident. The issue seems to be in the ODS passenger seat mat that determines when the airbag is active or not. If moisture is able to get within the mat, then it can short the circuit and cause airbags to not deploy. My car was "supposed" to already been fixed with the issue in 2015 on the recall #WQT55, NHTSA Campaign 15V419000, but I don't believe the underlying issue was fixed correctly or the same part has failed again. Looking further into recalls, the exact same issue is happening again with Subarus with #WRA-24 and NHTSA campaign 24V227. The dealer has asked me to pay over $1700 on to replace this part. …

50% of the time or more, the ignition refuse to release the key. When turning the key to take it out of the ignition, there are three clicks before the key releases. Mine often clicks twice and will not go beyond this point. I searched and found at other people have the same problem. Sometimes if I place my foot on the brake and put it in neutral, then back to park it will release, but this does not work every time and it can lead to much confusion when parking. People sometimes can't tell if im trying to move or park. This doesn't appear to be an isolated incident
The fan controls in the center of the dash failed. Fan speed 1&2 work, but 3&4 do not. After pulling the center dash controls out, I found that the plug connecting the fan speed controls to the wiring harness was burnt. This is a concern cause it could have burned other components or caused a fire.
On the heater controls, for the fan speed, the connector on the back caught fire, I was able to stop it in time to prevent any further damage. My mother in law and my son ride that car daily, could of been a disaster. I have purchased a new part, replaced the plug, and same issue occured, started smoking and ruined another heater control. Used auto part locations near me reported the same issue on at least 3 other cars. See attached images.
Tl* the contact owns a 2012 Subaru Impreza. The contact stated that the air conditioner and heater stopped working.

Driving down mountain after day of skiing. Roads were treacherous and icy. 20 minutes into the drive, driver and passenger airbag lights turned on, indicating that airbags would not deploy in the case of a collision. Several months later I was wearing a damp bathing suit while driving and the same situation occurred, indicating that the airbags would not deploy in the event of a collision. On another occasion, I was driving on a hot day with the windows down. I was sweating quite a bit and the airbag light on my Subaru Impreza turned on yet again. This issue was brought up with the dealership while the car was still under warranty. The dealer's service department simply reset the sensor, not solving the issue or comprehending the severity of this issue. …
