Subaru Outback electrical problems

"I own a 2018 Subaru Outback VIN [XXX] . I have experienced a recurring failure with the TPMS (Tire Pressure Monitoring System) three times within the same year. In January 2026, I brought my vehicle to the dealership and had to replace the TPMS sensors. Shortly after, the issue returned and I had to replace the TPMS module. I picked the vehicle up on Monday, May 18, 2026, and by Wednesday, May 20, 2026, I had to return it to the dealership again for the same recurring problem. This is the third repair for the same system failure within 2026. I have open case with Subaru of America regarding this matter (Case Number: [XXX]). Despite multiple repairs, the root cause has not been resolved. I am concerned this is a safety issue as a malfunctioning TPMS system can fail to alert the driver to dangerous tire pressure conditions while driving. I am requesting that NHTSA investigate whether this is a widespread defect in 2018 Subaru Outback vehicles. I have spent over $2,000 out of pocket costs to date.

Odometer Fraud. The contact purchased a 2018 Subaru Outback. The owner located a torn receipt with the discrepancy located in the vehicle. The vehicle was a private sale.

The 2018 Subaru Outback 8" Starlink infotainment system is beeping, switching between the screens, try to disconnect my phone, changes radio stations doesn't recognize when I touch a button on the screen. That it is a distraction while driving as it is one annoying, two I try to get it to stop eventually just have to turn it all off so then I drive with no navigation screen or radio. I am well aware this is a widespread known issue affecting 2018–2019 Outbacks and Legacies, This has been an ongoing issue for the last 6 months in my vehicle.

The contact owns a 2022 Subaru Outback. The contact stated that while coming to a stop on several occasions, the vehicle unexpectedly stalled. Several unknown warning lights were illuminated. The vehicle was able to be restarted. The vehicle was taken to the dealer. The contact was informed that the battery was functioning properly. The vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure, and a case was filed. The failure mileage was approximately 36,249.

HVAC system heating to dangerous levels and still radiating heat into the cabin even after HVAC system was turned off. To mitigate, direction was changed to feet. Temperatures of over 100 degrees F were observed for sustained periods. Issue is intermittent, however it was reproduced consistently when it was cold outside (cold being cooler than 55 degrees F). I set the temperature to 65 degrees F with the AC on and recirculate, however it didn't make a difference. When this bug happens, it puts out a lot of heat and the only way to get it to cool is to drop it to the lowest cool setting ~60 degrees. I took it in 3 times to the dealer and they said they were unable to reproduce the issue, and while it has been intermittent, I was able to frequently reproduce the issue when it was cold outside, including yesterday, 04/19/26. It does not appear to happen when it's warm outside, although it hasn't been consistently warm to be able to conclude that at this point. What is certain is that the system does not appear to be functioning as designed (which is what both the dealer and Subaru of America (SoA) claim, SoA just restating the dealer's comments). Both LaFontaine Subaru of Commerce Township, Michigan and Subaru of America have at this point ignored the issue despite me bringing it up consistently.

April 3, 2026: my 2025 Subaru Outback Premium (VIN [XXX] , 2,052 miles) suffered simultaneous failure of multiple safety-critical systems due to corrosion on a CAN bus pin in the driver door wiring harness (Subaru part #XXX) at its dash harness connection, caused by water intrusion into the cabin. Trip start: EyeSight, collision avoidance, blind spot, and lane assist all offline; BRAKE indicator illuminated with no brake engagement. Minutes later, airbag warning activated. Dealer service advisor described the dash as "lit up like a Christmas tree." While reversing through a 3-point turn on a commercial drive used by heavy trucks, I LOST STEERING at single-digit speed. 60 seconds further would have placed me on an inclined high-traffic road near a freeway interchange. Vehicle was towed by Subaru from the failure location. Confirmed by authorized dealer Driveway Subaru of Moon Township (Invoice #680646, warranty claim). Subaru SSM4 scan recorded 17 unique DTCs across 10 control systems, including C1460 Brake Booster Abnormality; U1131 Lost Comm Power Steering Control Module; U0151 Restraints Control Module; U0122/U1122 VDC; U0126 Steering Angle Sensor; plus multiple EyeSight faults. Dealer documented moisture on both A-pillars, driver kick panel, standing water in cupholders and center console. Prior intermittent symptom: passenger seatbelt alarm on empty seat, two occasions in prior months, consistent with past-status U0151 on scan. Dealer cleaned the corroded pin but did NOT identify or seal the original water ingress point. Vehicle remains in dealer possession. Subaru of America Customer Advocacy Case #XXX-XXXhas declined repurchase/replacement, stating vehicle is "operating safely as designed." I dispute this conclusion: the ingress source is unremediated and recurrence risk has not been addressed. Repair invoice, full DTC scan, SOA correspondence, and owner statement available on request.
