Filed Mar 4, 2025 · Airbags, Electrical · 97,803 miles · CT

The contact's girlfriend owns a 2012 Subaru Outback. The contact stated that the vehicle hesitated while starting. In addition, the contact attempted to jumpstart the vehicle; however, the vehicle failed to start. The check engine warning light was intermittently illuminated. The contact stated that during rainy weather, several unknown warning lights were illuminated. The contact scanned the vehicle with an OBD2 scanner and retrieved DTC codes: P0420 (Catalytic convertor) and P0057 (Ignition System). The vehicle was taken to a local dealer to be diagnosed. The contact was informed that there were failures with the rear brake pads, rotors, PCV valve, valve cover gasket, engine air filter, catalytic converter heat shield; and a cylinder #4 misfire. The DTC codes P0304, and P0420 (Catalytic convertor) were also retrieved. The contact was informed that the catalytic converter needed to be replaced first. The contact stated that several repairs were made prior; however, the failure persisted. Upon further investigation, the contact related the failure to Subaru Service Program Bulletin: WQC-39, WVY-35, WUF-91r, TKC-19R, and the federal safety agency Campaign Number: 20V003000 (Air Bags); however, the VIN was not included. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 97,803.

The last incident? I couldn't recover my intentions. (Incidents of random acceleration seem to only happen when I am turning). The last incident occurred in my mall parking lot.. I was about to turn and suddenly the car shot forward. I could have fought to maintain my turn but that would have been aggressive maneuvering. Nothing, thankfully, was in front of me, so this was the first time I was deviated off course. 1 - random acceleration 2 - if my reflexes were not quick enough, there would have been vehicular accident and/or pedestrian being struck 3 - no... not able to duplicate. 4 - no check engine lights prior. One instance, as I avoided a collision, that threw a code (CEL) but scanner didn't see any codes. CEL went away 3 days later. NOTE: I am in North Bay, Ontario, Canada

Couple weeks back while driving on the highway my check engine light came on along with different lights and transmission oil warning and car immediately lost power. I was able to pull over without incident. Then I took it to my local mechanic, they changed the transmission fluid and changed some fuses. It seemed fine after the repair and I started to drive home, but again the same warning lights came on and the repair shop advised me to take it to the nearest Subaru dealer which is an hour away from my home. I paid for the diagnostics and the dealer concluded the problem as follows "Transmission Valve Body: faulty causing check engine light and at oil temp light, will need to sit overnight for sealant to dry before fluid can be added.". I did some research and found that this is a known problem for the 2012 Outback and Subaru had a 10 year/100k extended warranty for the exact problem and didn't do any recall even though so many vehicles were affected and are being affected every day. There are numerous complaints regarding this. Though as being 2nd owner and have driven just 9k miles in 2 years while performing regular maintenance this is very unfortunate and dangerous. I emailed the manufacturer to cover this since 100k was up and it should have been recalled. This was their response" Dear [XXX]: Thank you for contacting Subaru. Your vehicle did have a 10 year/100,000 mile warranty for extended transmission coverage. Regrettably, it is far outside of warranty and Subaru of America would not be in a position to consider financial assistance towards your repair. I will notate your feedback in the case for Product Development to consider when designing future models. Sincerely, David Subaru of America, Inc. Customer Advocacy Department 1-800-SUBARU3 (1‑800‑782‑2783) Case Number: [XXX]" They should recall the vehicle for this problem or offer free repair.

No issues with the car since I bought it new and was dedicated to regular Maintenance. Less than a week after a regular scheduled oil change and driving on the main interstate highway cruising at 65mph, the car just suddenly jerked. I thought I had blown a tire but the Brake light came on and then soon after the engine light came on. I was able to get off the highway but the acceleration decreased to a slow crawl. I had it towed to the nearest Subaru dealership that morning in which they said the issue is that both 1 and 4 are not correctly firing. They checked the spark plugs and checked the injector, but both did not fix the issue. They have now told me that they need to get the engine pistons/valves "machined". They are reaching out to Subaru to see if they can help since there is nothing I could have done to prevented this issue and they are hearing more of this issue occurring in Subaru cars. I'm praying that Subaru will help me with my vehicle but am waiting to hear from the Subaru dealership.

1. Over the past months at different times the dashboard lights all start flashing the check engine cruise control breaks Flash on and off 2. Our safety's at risk because we don't know if the engine is needing repair or if it's an electrical problem or if the car's just gonna stop dead 3. We took the car in and they charged me $1500 for a new fan coil and it's still doing it 4. Yes there were many warning lights it has been happening for the past year and I've taken it in twice and it's still happening and now they're saying they have to replace the engine strap which is another $3000 this is ridiculous

Have been driving my car on the interstate for 6 hours and when this problem happened I was in cruise control. Out of no where a bunch of dash lights come on, (E brake and cruise control lights start blinking, traction control light comes on, and my check engine light comes on). I tried turning my car off for a few minutes and turning it back on but the lights still are blinking. I Googled my problem and found other people that have posted the same issue. I have also copied the found ID number for this issue: 10465487

2012 Subaru Outback stalls when braking. It stalls going up hills, on flat roads, after high speeds and after city driving too. The vehicle has shut off at stop lights, on/off ramps, and stop signs putting me and my family at risk of being rear-ended. It also stalls when parallel parking, increasing risk of being hit on city streets. No warning or check engine light. Subaru issued a bulletin about the issue but the local dealer and local mechanic were unable to replicate stalling on test drives.

I experienced issues with the engine of my 2012 Subaru Outback shutting down at times when coming to a stop, and also stalling/idling when accelerating (such as when entering freeway). My engine light and brake light also turned on at the same time. Very concerned, I took it in to the local Subaru service center at around 112,000 miles. They inspected the car and replaced 2 spark plugs, and must have restart the computer to turn the warning lights off. Recently at 117,000 after entering the freeway at night , my car roughly idled and the stalled and would not properly accelerate, almost causing me to crash as it happened suddenly while driving on freeway. The engine light was flashing and brake light came on as well. I immediately pulled over. After the Subaru inspection the next day, I was told that this was being caused by the torque converter and is a known issue on this model. This is a very dangerous issue, I believe that if this incident would have happened the next morning while on my commute instead of at the less busy hour at night, a crash would have occurred. I believe a recall is warranted on this dangerous issue as it is known by Subaru that this issue affects certain models and they will not provide much help to customers if they are past the extended warranty. The issue can occur past the 100,000 mile mark on an otherwise good condition and well cared for vehicle. This puts the customer and other drivers at great risk. I am very concerned and upset about the danger this put myself and others in. I was personally left on the side of the freeway at night at 7 months pregnant, but the situation could have been much worse. Since Subaru is not required to let customers know of this issue, customers may experience this issue without proper remediation until a serious issue happens.

On october 16th, 2020 while driving our 2012 subaru outback on the highway, the check engine light came on. My husband and I pulled over, lifted the hood and saw steam coming from the engine near the radiator. We took the car to the subaru dealership and the tech stated both head gaskets were failing. The vehicle had 156,000 miles on it and we ended up paying over $2500 in repair costs. Because of the age and mileage on the car, I did not plan to submit a repot to the federal safety agency. However, I was notified by a relative today that her 2009 subaru impreza with only 68,000 miles just experienced head gasket failure and the dealership quoted her $4500 in repair. I have encouraged her to submit the issue through the federal safety agency for further trending purposes as I believe this may be a safety concern with subarus.

Vehicle shutters and stalls when braking on a city street, especially in colder weather (I first noticed this in the winter of 2018). On sept. 13, 2020, the vehicle violently lurched forward as I pulled out on a city street at lower speeds. After this occurred, the check engine light, oil temp, traction control light, and brake light came on on the dash. Diagnostic showed a p0700 and p2764 error codes indicating a need for a valve body replacement. Service bulletin 16-107-17r indicated that when replacing the valve body a newly designed part should be used because the old part does not work as well. When I called subraru, they discouraged me from replacing the valve body with the originally designed part even if it was brand new. I do not feel safe driving this vehicle without this repair and I feel that because subraru has a newly designed valve body part to address this issue, that this issue is not the result of normal wear and tear but should be a considered a recall instead.
