Automatic Emergency Braking problems of the 2019 Subaru Ascent

Nhtsa vehicle safety complaint vehicle: 2019 Subaru Ascent VIN: 4s4wmafd3k3474603 mileage: 72,093 miles I am submitting this complaint because my 2019 Subaru Ascent experienced a serious transmission-related electrical failure that may represent a broader safety defect. Sewell Subaru of dallas diagnosed an internal failure of a transmission pressure sensor. According to the dealership’s written report, the failed pressure sensor allowed transmission fluid to leak into the electrical wiring harness. The transmission fluid then migrated through the wiring and into the bulkhead harness. The dealership advised that the fluid contamination had affected multiple parts of the vehicle’s electrical system and recommended replacement of the transmission wiring harness, engine wiring harness, bulkhead harness, engine control module (ecm), transmission control module (tcm), and related components. Because the wiring harnesses are routed throughout the engine compartment and vehicle, the repair also requires extensive disassembly of the vehicle, including disconnecting and removing numerous engine compartment components to access and replace the contaminated harnesses. The estimated repair cost was approximately $12,000. I also have video documentation of the dealership technician performing the inspection and explaining the transmission fluid contamination and migration through the wiring system. I am willing to provide the video, the dealership's written diagnosis, repair estimate, photographs, and any additional supporting documentation upon request. My vehicle falls within the published VIN range associated with Subaru recall wuv-07, which involved the cvt hydraulic pressure sensor harness and transmission hydraulic pressure system. That recall was later superseded by wrk-21. I understand that the published recall addresses electrical resistance and transmission hydraulic pressure readings rather than transmission fluid leakage.

Car has been not able to roll up driver side window for a year randomly. Suddenly 3 years old and battery is draining and rab and eyesight and engine light on. Took in and saying can’t replicate window after they did replicate it 3 months ago and did not solve issue. Did battery parasitic draw and numerous parts of car are draining battery. Cannot find source.

I leased a 2019 Subaru Ascent (VIN: [xxx] ), which is equipped with the eyesight driver-assist system. In the spring of 2019, while driving in a parking lot at night with low visibility and snow, the vehicle struck a pole. Despite the imminent collision, the eyesight system failed to engage pre-collision braking or provide any audible/visual warning to alert me of the obstacle. The system did not disengage or indicate it was unavailable due to weather; it simply failed to function, resulting in a collision. Following this incident, I immediately contacted Subaru of America to report the failure. At that time, Subaru representatives denied any defect existed and stated the system was not at fault. I have recently learned that this vehicle is part of the [xxx], et al. V. Subaru of America, inc. Class action 9[xxx]), which addresses defects in the pre-collision braking and lane keep assist systems. Crucially, I was never notified of this class action or the associated defect by Subaru. I received no mail, email, or other communication alerting me to this safety risk or my eligibility for repair/reimbursement. I only discovered this information via a third-party news source after the settlement claim deadline of September 27, 2025, had passed. Upon contacting the settlement administrator and Subaru of America in January 2026, I was told that because the administrative deadline has passed, no remedy is available. Subaru is effectively refusing to address a known safety defect on a confirmed affected VIN solely due to a missed deadline that I was never informed of. I am filing this complaint to document the failure of the eyesight system and Subaru’s failure to properly notify lessees/owners of known safety defects. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

The contact owns a 2019 Subaru Ascent. While driving 14 mph in a parking lot, the contact attempted to engage the eyesight pre-collision braking system; however, it failed and the vehicle crashed into a pole. The air bags did not deploy. A police report was not filed. There were no injuries. The dealer and manufacturer were not contacted. The cause of the failure was not determined. The failure mileage was 5,400.
