20 complaints have been filed with NHTSA for the 2021 SUBARU WRX. Below is a breakdown by vehicle component.

Most Recent Complaints

#11668435 | SEATS | | N/A miles
Manual (not power) Driver seat is loose-rocking car only has 47000 miles but this hardware failure will get worse over time definitely a safety concern if bolt breaks it appears that the plastic washer is wearing most likely poor material should be polyurethane or something like the form of a grommet that absorbs since vehicle has hard suspension NOTE: I have video however cannot create video < than 10mb
#11668269 | ENGINE | | N/A miles
In October 2024, my vehicle, a 2021 Subaru WRX STI, was purchased from a Toyota dealership (Fort Bend Sterling McCall Toyota). The dealership sold the vehicle with an oil issue and a modified ECM. This issue caused catastrophic engine failure while driving. The vehicle stalled and could not be started. Subaru dealership technicians confirmed the cause as improper service leading to catastrophic oil starvation. The failure put both myself and others at risk, as the engine lost power mid-operation on a busy road. The vehicle was towed to a certified Subaru dealership, where it has been detained since December 2024. Despite being under warranty, repairs have been delayed for over 6 months due to blame disputes between the dealership, the manufacturer, and the extended warranty provider. There were no prior dashboard warnings or messages before failure, only loss of power and engine noise at the time of the incident. The vehicle has been fully inspected and documented by the Subaru service center, and all evidence has been preserved. I have been without a primary vehicle for over 7 months.
#11666353 | ENGINE | | N/A miles
I am filing this complaint to report a serious safety concern involving my 2021 Subaru WRX, which is currently covered under the manufacturer’s powertrain warranty as well as an extended warranty. Subaru of Ontario, an authorized Subaru dealership, failed to properly diagnose or repair ongoing engine issues during multiple service visits. Despite documented problems, the vehicle was released to me in a condition that was unsafe to operate since their location did not have a loaner, fully aware of the issues at hand, exposing me and my family to serious risk while driving. As a result of this negligence, the engine has now deteriorated to the point of needing a full replacement. Subaru of Ontario is attempting to charge me $3,000 for an engine replacement, despite warranty coverage that should fully apply. The dealership has refused to acknowledge their failure in prior inspections or take accountability for releasing an unsafe vehicle back onto the road. I am reporting this as a vehicle safety hazard and potential warranty fraud, as the dealership’s actions directly led to unsafe operating conditions and are now being used as justification to deny coverage. I urge the NHTSA to investigate both this specific incident and whether this may reflect a larger pattern among Subaru service centers. I am prepared to provide service records, warranty documentation, dealership communications, and supporting evidence upon request.
