2026 Subaru Trailseeker, purchased new May 19, 2026. The 12V auxiliary battery failed completely after 3 days parked on June 17, 2026. Traction battery was at 65% charge at time of failure. All vehicle systems were unresponsive. Couldn't open doors, do anything. When the 12V drains fully on this platform, the wheels lock and the vehicle cannot be moved by a standard tow truck, creating a stranding risk in any location where jump-starting is not possible. Since the incident, I have installed a Bluetooth battery monitor. Data collected June 22, 2…
Car bought new April 2026. At 1700 miles the 12v battery drained completely overnight after having been driven not 8 hours earlier. Car parked in garage, windows down and car left unlocked. Car was charged to 95% and did NOT have the charging cable on. Woke up to drive it and it wouldn’t start. Totally dead. Had to have it towed. Jumping the car did by tow truck did start the car to allow me to get windows up and car in neitral
I purchased my vehicle brand new on June 6, 2026, with only 13 miles on the odometer. After driving home (about 44 miles) and another 10 miles the following day, the vehicle sat for just two days. When I tried to start it, the 12-volt battery was completely dead. The dashboard displayed a Parking Brake Malfunction message, multiple warning lights flashed, and then everything went black. I contacted the dealership, and Subaru Roadside Assistance responded. The driver recommended jump-starting the vehicle instead of towing it because it couldn't…
I went to start my 2026 Trailseeker and the 12 volt battery was dead. I contacted Subaru Roadside Assistance to jump the vehicle. After they jump started the vehicle I received the following warnings on the dash.."Brake Override Malfunction..Visit Your Dealer".."Braking Power Low..Visit Your Dealer." "Braking Power Low Stop in a Safe Place See Owners Manual." The car was un-drivable as I was unable to release the brake. I disconnected the battery cables and those warnings went away but the EV malfunction light remains on. The car was towed to t…

The day before that all these issues started popping up my battery was completely dead, and I had to jumpstart the 12 V battery the next day while I was driving down the highway I started getting all these error messages and also the video from the Ford camera started glitching with my navigation.

Vehicle has an excessive headlight unit shaking which causes light beam to oscillate at night time while driving, very distracting and dangerous for upcoming traffic.

On 3 occasions my 12v battery has been completely drained by a defect in the DCM/software that causes it to ping for hours at a time. I was able to jump start the car, but this issue may leave drivers who don’t carry a jump pack stranded. The depleted battery state may also affect electrical systems even when the car is started

Car bought new April 2026. At 1700 miles the 12v battery drained completely overnight after having been driven not 8 hours earlier. Car parked in garage, windows down and car left unlocked. Car was charged to 95% and did NOT have the charging cable on. Woke up to drive it and it wouldn’t start. Totally dead. Had to have it towed. Jumping the car did by tow truck did start the car to allow me to get windows up and car in neitral
I purchased this vehicle in April 2026. Using it vehicle normally results in the 12V battery becoming discharged leaving the car unable to start with me stranded. This has happened 3 times. Jump starts are successful and keeping the car active partially recharges the 12V battery. A dealer has replaced the 12V battery under warranty, but this has not fixed the problem. I'm now taking steps to keep my 12V battery charged by using a trickle charger most nights. This should not be needed with a new vehicle!
The day before that all these issues started popping up my battery was completely dead, and I had to jumpstart the 12 V battery the next day while I was driving down the highway I started getting all these error messages and also the video from the Ford camera started glitching with my navigation.
Hi. Simply went out to start my 2 week old Trailseeker and the battery was dead. This is a major safety concern to me. What if the battery randomly dies while I am driving or what if I am in an area that I want/need to leave but my car won’t start.We are high fire danger here in [XXX] . I am a single older woman and this really concerns me. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
ELECTRCAL SYSTEM - Low Battery; DEAD Battery. My Subaru Trailseeker was purchased on 1st June 2026. During the first two months I noticed the comment "Low Battery" as I started the vehicle. (It is possible that I missed some "Low Battery" alerts as these flash on the dash screen momentarily as I press the Start Button). Then on 2nd August 2026 I could not start the vehicle at all and my battery tested DEAD. I jump started the vehicle and recharged the 12V DC Lead battery to 99%. Next morning the battery had drained to 26%. Besides being a pain …
We purchased the 2026 Subaru Trailseeker Limited in April, 2026. We have used it regularly (every few days since purchase). I experienced a display of "Low Battery", on the heads up display prior to charging. Once the traction battery recharged I did not see the warning. I subsequently installed a ANCEL BM200 battery monitor after hearing of parasitic drain on the 12 volt battery resulting in inability to start. Since monitoring, I have measured said drain and continued to operate the vehicle almost daily to recharge the 12 volt battery an…

I purchased a new 2026 Subaru Trailseeker on 06/22/2026. On 07/30/2026, the vehicle became completely inoperable because of a discharged 12V battery. The vehicle would not enter READY mode. Pressing the brake pedal and the START button had no effect. The interior lights would not turn on, and the vehicle was completely without power. Before the vehicle was jump-started, I measured the 12V battery voltage at 7.4 volts. Roadside assistance was required to jump-start the vehicle. After the jump start, the vehicle immediately entered READY mode…
