Subaru Outback electrical problems

Subaru settled a class action lawsuit regarding faulty battery and DMC component that drains the battery continuously. My dealer just replaced my battery and DCM under warranty (I'm assuming the warranty is a result of the lawsuit). However, this does not ultimately remedy the problem. The new DMC will continue to draw on the battery causing future reoccurring issues. Subaru needs to make good on this problem in a permanent way.

The navigation screen that controls apps, radio, navigation and phone has delamanated and now has a mind of its own. If my phone is connected it will actually start making random calls while driving, radio sound changes, screens will switch on tjeir own while driving. It started a a year ago. I just thought it was a periodic glitch. It has progressly gotten worse. I saw there was a class action suit and didn't inform?

PARASITIC BATTERY DRAIN. I JUST BOUGHT THIS USED SUBARU OUTBACK IN JULY 2024. SINCE THEN, (WITHIN 8 MONTHS) THE CAR HAS HAD A DEAD BATTERY TWICE, IN 11/24 AND 2/25. I HAD TO HAVE THE CAR JUMPED STARTED BY AAA SERVICES. THIS IS MORE THAN AN INCONVENIENCE NOW. IT HAS BECOME A SAFETY ISSUE IF MY CAR WON'T START IN AN EMERGENCY SITUATION. I HAVE TAKEN THIS TO THE DEALER WHERE I BOUGHT IT AND THEY DIAGNOSED A 6 DAY BATTERY DRAIN TIME. SEE UPLOADED INVOICE. THIS IS A KNOWN FAULT REGARDING THE DATA COMMUNICATIONS MODULE (DCM) PREVIOUS SETTLEMENT AGREEMENTS ONLY REIMBURSED FOR COSTS OF BATTERY REPLACEMENTS, DIAGNOSIS UP UNTIL 2023. THE UNDERLYING PROBLEM IS NOT FIXED

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 NHTSA 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 head unit on the vehicle has an issue where it bubbles and it’s causing the touch screen to spaz out, change sources, etc creating a terribly distracting driving experience and you are unable to turn it of. The screen flashes, the radio changes stations, it messes with the navigation rendering it useless, etc. it’s a known issue and Subaru settled a class an action lawsuit related to it for 2018 models but has not issued recalls to for any year models. They should fix the issue on all models. It has been going on for months.

Parasitic battery drain when vehicle is turned off. The DCM module in these vehicles will not shut off properly and continue to drain the battery. Subaru has firmware on the vehicle that will not fully charge the battery when driving to save fuel. The vehicle has had 6 or more instances over the past two weeks where the car was undriveable unless jumped from another vehicle or a boost device is used.

For our 2020 Subaru Outback, we are on our 3rd battery at only 49k miles. The car died again today. Thankfully AAA was able to jump it after a friend tried unsuccessfully. We suspect all of this battery drain, failure and replacement has been due to the known Data Communications Module (DCM) issue on recent Subaru’s. I have an appt w the dealer in Santa Monica tomorrow morning to have it diagnosed.
