Affected Years: 2020 Subaru Legacy. Our law firm is also investigating 2021, 2022, 2023, 2024, 2025, 2026 Subaru Legacy for the same issues.
These issues seem to arise from defects in the Transmission Control Unit (TCU).
There is no question that, as a society, we have become very reliant on technology in our vehicles. When it breaks, we are going to get it fixed. When it doesn’t get fixed, we find ourselves back at the dealership waiting on a repair, or leaving it for days to get fixed this time. Solutions like taking the transmission out of tow mode to avoid downshifts, and manually shifting yourself is more of an in the moment fix, bringing your camper or boat back over the weekend, than anything you might choose to live with long term. This is common. This is something that should work when you need it to, and you are well within your rights to expect Subaru to be able to fix this issue.
It also tells you that you might have an issue with your Subaru that has been reported by other owners, and you may have just learned that you need to contact Guardian Lemon Law and ask for a lemon lawyer to sue Subaru for Transmission Failure (TCU Error) when they can’t fix it after a few tries.
The Symptoms Of The 2020 Subaru Legacy Reduced Power Issue
Reports of this issue from consumers indicate that the vehicle fails to maintain speed under acceleration, often experiencing a severe loss of power. While the engine itself isn’t losing power, it isn’t transferring to the wheels via the transmission. This is caused by a TCU error, resulting in slippage in the CVT drive chain. There was a safety recall, WUV-07, that defined the issue further as an error where the clutch would engage prior to the chain being fully secured.
The resulting loss of power is staggering and not easy to resolve. It manifests itself between 35 and 50 mph. The TCU program needs to be updated as it is causing the CVT sensor to misread the hydraulic pressure, causing chain slippage. Without being corrected, the chain will eventually break.
In the recall, Subaru will update the TCU and conduct an inspection of the transmission. If there is any physical indication that the issue has occurred, the transmission will be replaced.

Lemon Law Basics
California Lemon law, written and titled as The Song-Beverly Consumer Warranty Act, was passed in 1970 and signed into law in 1971. Its original purpose remains to protect and provide a resolution for buyers who are experiencing issues dealing with a manufacturer’s express warranty. To qualify, the issue and the vehicle have some qualifications that must be met. You must also be within the statute of limitations as set by state law. More on both of these items later.
If your vehicle feels like it is losing power and Subaru is struggling to fix it, Guardian Law Firm can provide a Subaru Legacy lemon law attorney to help you confirm that your vehicle meets the qualifications for a lemon law claim.

The Qualifications For A Lemon Law Claim In The State Of California
The qualifications listed below are generally straightforward. The key part of any lemon law claim is that the vehicle has been repaired for the same exact issue, without resolution. The first three items should all be met. The qualifications are:
- The vehicle must be under factory warranty at the time of the initial report, and remain so during any repair attempts
- The owner of the vehicle has not operated the vehicle in a way that causes or contributes to the reported problem
- The dealer or representative has been allowed a number of reasonable repair attempts to address the issue. This means a minimum of two attempts for any safety-related issue, and at least four attempts for anything non-safety-related
- The cumulative repair time for this issue is greater than 30 days in total, and the Legacy cannot be used by the owner
- The issue being experienced has a direct impact on the safe operation, the actual use, or the value of the vehicle to you

The Statute Of Limitations For Filing A Lemon Law Claim Or Lawsuit
Lemon Law in California sets the time limit on filing a lawsuit or claim as the earliest of two different dates directly related to your vehicle purchase and delivery. The first date is one year from the expiration of your vehicle’s factory warranty. The second date is six years from the date you took delivery of your vehicle from the dealer.
Reviews And Filing A Lemon Law Claim
There are a few things we do before we let the client know that a lawsuit is an open option. We’ve already covered the evaluation process. Once that is done, we review the documentation that you have regarding your purchase. Your documentation should address the areas and contain the details listed below:
- Any records of your repair trips, including the dates and times for drop off and pickup, and clearly documenting the issues and attempts at repair.
- All electronic communication that shows what was communicated to you during the dealership repair efforts
- All original documentation for the vehicle purchase, as well as the warranty details, provided if the vehicle was used and came with a pre-owned certified warranty from Subaru
What Does Winning A Lemon Law Claim Look Like?
The winning result of any lemon law claim, lawsuit, or settlement is going to be one of two things. The manufacturer conducts a buyback of your vehicle, or replaces the vehicle with a similar or like model. There is always the possibility of a settlement, and it may include a cash payment to you for the resolution of the issue, you keep the car, and agree to bring no additional legal challenges over the vehicle to Subaru.
The buyback option will include all the costs of the first purchase, including tax, tag, and title work, fees, etc. Subaru will deduct a rate per mile for the mileage you put on the Legacy before the first visit for the repairs. The other item the law requires is that the manufacturer cover your reasonable legal fees. This means that we can sue Subaru for selling you a defective, lemon Subaru Legacy, and Subaru is on the hook for covering the associated costs of fees and services on your behalf.
