2026 Subaru Trailseeker owner complaints

Vehicle charged to 87% of traction battery capacity on 6/18, early morning. Vehicle only used Saturday morning for about 2 miles. 12V battery dead today, Monday June 20 at 12PM

On multiple occasions, my vehicle's 12v battery has completely discharged presumably from parasitic drain from connected services communications. The first time the 12v was completely discharged was on 6/10/26 following between 24-48 hours of sitting idle without being driven. It was recharged and the following day had discharged almost completely, giving a warning that it needed to be charged back up. This was after ~24 hours without being driven. I ultimately brought it to the dealership on 6/17/26 where they were unable to replicate the issue initially and cleared the vehicle to be picked up on 6/19/26. Upon my arrival to pick up the car the following day (6/20/26), the 12v battery was dead on the lot. My vehicle then remained at the dealership for continued investigation before ultima

The 2026 Subaru Trailseeker, Subaru Solterra, and the Toyota Equivalents have a parasitic battery drain issue that will leave you stranded. Something causes the DCM to continue to pull from the battery when the car is off and after a few days will completely drain the 12V Battery System. This can damage the 12V Battery system and poses a safety issue as that is the computer system that maintains the traction battery system along with all the safety features.

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 the dealership and in their possession, the battery was dead again and had to be jumped by them. They said they found nothing wrong with anything. I requested a new battery and they said it would not be approved by Subaru as they found nothing wrong w

6 week old car had battery die in a remote location without cell service.

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

12 volt battery dead after 45 hours of the car sitting locked, not in use. Subaru roadside service called and dispatched to jump start the vehicle

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 be shifted into neutral with a dead 12-volt battery and would need to be dragged. After the jump, he noted the high-voltage battery still had about 70% charge and suggested driving the vehicle to recharge the 12-volt battery. The dealership tested

The 12v Lead Acid Battery is draining prematurely solely due to the first party Subaru Connected services application. My vehicle does not have any 3rd party applications, and yet every night there is a sawtooth drain occurring on the battery bringing it from 12.4v down to 11.7v. The vehicle is pinging/uploading or transmitting data at an excessive rate every night - [XXX] It is further evidenced by the driver monitor alert activating multiple times in the middle of the night. With this rate of drain, the 12v battery would die within 48-72 hours without being recharged by the traction battery when the vehicle is operating.

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)

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!

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

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, 2026 shows consistent parasitic drain throughout the day, with voltage declining from ~12.2V at rest and recovering only briefly when the DC-DC converter cycles (~14V spikes). The battery does not hold charge between cycles. No warning lamps appeared

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.
