Subaru filed this with NHTSA as a manufacturer communication dated Sep 29, 2025, received Oct 2, 2025, about the electrical system. It names 14 model years (2020–2025). A manufacturer communication is not a safety recall: it is the manufacturer telling its dealers how to diagnose or repair a condition, and whether the work is paid for depends on the warranty in force. Quoting the number at a service desk can save a diagnosis.

The summary is NHTSA’s abstract of the document, as filed under 49 CFR 579.5. One communication is usually filed as several documents — the bulletin, a dealer notice, an owner letter — and the number on any of them finds this page. A PDF link is shown only once NHTSA’s own server has been seen to serve that document; the rest are checked over the following nights. Quote the number at a service desk; it is what the dealer’s system is keyed on.

What owners reported
Source: NHTSA complaint databaseOwners of the 14 model years this bulletin names have filed 2,181 complaints with NHTSA since 2015. 464 of them name Electrical System — the same broad component group this bulletin is filed under. NHTSA groups complaints coarsely, so that means the same area of the vehicle, not necessarily the same fault.
On the 2020 Subaru Outback, the 115 owners who gave an odometer reading for Electrical System reported it at a median of 5,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
The car has randomly on multiple occasions failed to accelerate then jump forward hitting the rev limiter. This has happened while merging back into traffic including 55 mph roads creating concern for being rear ended and also concerns for hitting vehicles in front when the car jumps forward as there is no control over it.

I bought this 2021 Subaru Outback in jan 2, 2021. In mid feb, I drove the Outback to lake tahoe. On my way, I went to costco gas station for gas after 1 hour highway driving. The car was just dead after refueling. I called roadside assistance not knowing what happened. The car was jumpstarted.

1. The backup and front camera are downgraded from previous models of Outback. Subaru of america denies this. The night visibility is dangerous. The dealership agrees. I have purchased four outbacks in six years and I know what I AM talking about. It is totally dangerous at night.

A complaint is one owner’s account, not a defect finding, and a bulletin is not a recall. Nothing here says this bulletin was issued because of these complaints, or that the repair it describes fixed them. Complaint files on this site begin in 2015.

Common questions
Source: NHTSA, 49 CFR 579.5Is Subaru OTA Software Update (1010 a recall?
No. A manufacturer communication is a manufacturer communication filed with NHTSA under 49 CFR 579.5; a safety recall carries an NHTSA campaign number (two digits, a letter, six digits) and a federal duty to repair for free. Check the vehicle’s recalls by VIN at nhtsa.gov/recalls, or on its page here.
Is the OTA Software Update (1010 repair free?
Not automatically. A service bulletin describes how to diagnose or repair a condition; who pays depends on the warranty in force, any extension, and the dealer. Quoting the number can save a diagnosis either way. Every Subaru warranty extension on file lists the ones Subaru has filed.
Which vehicles does OTA Software Update (1010 cover?
The manufacturer filed it against 14 model years: 2024 Subaru BRZ, 2023 Subaru BRZ, 2022 Subaru BRZ, 2022 Subaru Legacy, 2021 Subaru Legacy, 2020 Subaru Legacy and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
