2023 Subaru Solterra

NHTSA VEHICLE-DATA MISMATCH: The VIN entered in the vehicle-information field belongs to a Toyota-branded 2023 bZ4X AWD Limited, as shown by the vehicle, Toyota app, factory window sticker, and Toyota dealer records. NHTSA's form incorrectly displays a 2023 Subaru Solterra. NHTSA's VIN decoder identifies the manufacturer as TOYOTA MOTOR CORPORATION but assigns Subaru/Solterra as the make/model. Please correct the classification and associate this complaint with the 2023 Toyota bZ4X. On August 10, 2026, at about 18,309 miles, my wife was driving with our daughters as passengers when the vehicle displayed Brake System and Electronically Controlled Brake System malfunction warnings. Braking felt abnormal, and the vehicle felt harder to drive and brake. The Toyota app recorded the same active faults. Its Brake System alert stated that a malfunction had been detected, continuing to drive may be dangerous, and the driver should stop in a safe location and contact a Toyota dealer. Its Electronically Controlled Brake System alert stated that a malfunction in the Electric Control Braking System had been detected. The driver stopped, and we removed the vehicle from service. It will be transported rather than driven. No crash, fire, injury, or fatality occurred. The vehicle has not yet been inspected, and the components remain available for inspection. The lower front bumper has minor scuffing and slight mis-seating visible on close inspection. Its origin is unknown; there was no known collision, and possible curb contact is speculation. I am disclosing it without asserting any causal relationship. Please record and evaluate this in-motion brake-system and electronically-controlled-brake failure.

November 1, 2024 (46,750 Miles): Vehicle suffered an initial internal high-voltage electric A/C compressor meltdown (Diagnostic Trouble Code B14721C). The authorized dealership replaced the compressor under warranty but left the original, contaminated micro-channel condenser assembly in the vehicle, attempting to clear it via a basic fluid flush. January 15, 2026 (121,269 miles): Vehicle was brought to an authorized Subaru dealer for the mandatory Federal Safety Recall WRD-25 (NHTSA Campaign 25V577). The software patch was applied, and the dealership explicitly stated that the A/C compressor was in good working condition at that time. No physical flush or deep system contamination audit was conducted. July 2026 (132,911 Miles): Only six months after the recall certification, the high-voltage electric compressor suffered a subsequent, total mechanical failure. The servicing dealership confirmed that the closed thermal loop is actively contaminated with metal debris. Because parallel-flow EV condensers cannot be flushed clear of metal shards, the leftover debris from the 2024 warranty failure acted as a physical abrasive, causing the rapid destruction of the replacement compressor despite the dealer's recent confirmation that it was functional. Safety Impact: The vehicle's windshield defroster and defogger systems are completely inoperative due to this compressor failure, recreating the exact visibility hazard targeted by Safety Recall WRD-25. This failure also impacts the high-voltage EV battery pack's thermal management system. Widespread Component Pattern: There is documented community-wide evidence on automotive safety forums indicating that numerous 2023–2025 Solterra and bZ4X owners are suffering identical post-recall compressor failures. The factory WRD-25 software patch simply adjusted the ECU failsafe programming to keep the defroster running; it did not fix the physical fragility or preexisting mechanical degradation of the compressor.

I had been hearing a humming noise for around a year and when reported to the dealer I was told that the rear electric motor had to be replaced. I had been researching online about this issue and apparently, is something a lot of Solterra owner have gone through. After a week of the car at the dealer, Subaru still doesn't approve the repairs that should be under Power Train guarantee. Should this be something to be part of a recall already considering so many public reports of this issue?

The contact owns a 2023 Subaru Solterra. The contact stated that while the vehicle was parked and occupied, while attempting to start to the vehicle, the horn sounded unexpectedly. Several warnings lights illuminated, and the gear shifter failed to shift to drive(D). A dealer was contacted. The vehicle was taken to the dealer, where it was diagnosed, and determined that the battery needed to be replaced. The contact stated that the failure had occurred more than eight times. The battery was replaced twice. The manufacturer was notified of the failure and informed the contact that the battery would be replaced under warranty. The approximate failure mileage was 15,000.

When the sun is at certain angles in the middle of the day, direct sunlight bounces off of the high-gloss plastic trim around the shifting knob directly into the driver's eyes. This is distracting and makes it hard to see the road.

The contact owns a 2023 Subaru Solterra. The contact received notification of Subaru Campaign Number: WRD-25, and the vehicle was taken to dealer, where the repair was completed; however, four days later, the vehicle made an abnormally loud sound while the HVAC system was engaged. Additionally, the HVAC system became inoperable, and the defroster and defogger were inoperable. The vehicle was taken back to the dealer, where it was diagnosed with an electrical compressor failure. The contact was informed that there would be a charge for the repair; however, the contact stated that the repair should be covered by the manufacturer because the manufacturer’s recall repair had failed to prevent the failure. The vehicle was not repaired. The manufacturer was notified of the failure and referred the contact to the Claims Department; however, the Claims Department staff was on leave. The failure mileage was approximately 48,000.

I was driving and my SOLTERRA windshield just suddenly cracked. There are many videos online of how the newer Subaru models crack because of thinner glass

In light snow, the car automatically braked at speed causing the car to veer off the road after skidding, multiple times. The "safety" features of this car make it dangerous to operate.
