The Prius IPM Settlement Covers Inverter Problems in Specific Model Years
Toyota reached a settlement in 2023 covering inverter power module (IPM) failures in certain Prius models. The settlement applies to 2010–2015 Prius vehicles that experience inverter problems within 10 years or 150,000 miles from the original purchase date, whichever comes first. The inverter converts DC power from the battery into AC power needed to run the hybrid system, and when it fails, the vehicle typically won't start or loses hybrid function.
Under the settlement, Toyota agreed to repair or replace the inverter at no cost to owners who meet the coverage window. This is separate from Toyota's standard warranty and applies even if your vehicle is out of warranty or you are not the original owner. The settlement does not require you to join a class action lawsuit or pay any fees to receive the repair.
The settlement was approved by a federal court in California and covers vehicles registered in the United States. If your Prius is within the model years and mileage range, you can take it to any Toyota dealership to have the inverter inspected and repaired under this program.
Key Takeaways
- The settlement covers 2010–2015 Prius models with inverter failures up to 10 years or 150,000 miles from original purchase, whichever is first.
- Toyota will repair or replace the inverter at no cost; you do not need to pay anything or join a lawsuit to receive the repair.
- Any Toyota dealership can perform the work under the settlement, and the repair is covered regardless of your vehicle's current warranty status.
- You should bring your vehicle to a dealership with proof of purchase or registration to confirm coverage and schedule the repair.
Which Prius Model Years and Mileage Are Covered
The settlement applies to Prius vehicles from model years 2010, 2011, 2012, 2013, 2014, and 2015. Your vehicle must have been registered in the United States and must not have exceeded 150,000 miles at the time you seek the repair. The coverage window runs 10 years from the original purchase date, so a 2010 Prius purchased in January 2010 would be covered through January 2020, regardless of current mileage.
If your vehicle falls outside these model years—such as a 2009 or 2016 Prius—it is not covered by this settlement. Similarly, if your Prius has more than 150,000 miles, the settlement does not explore. However, you may still have coverage under Toyota's standard warranty or extended warranty if you purchased one, so contacting a dealership to discuss your specific situation is worthwhile.
What Happens When You Take Your Vehicle to a Dealership
Contact your local Toyota dealership and tell them you want to have your Prius inspected under the IPM settlement. Bring your vehicle registration or proof of purchase to confirm the model year and original purchase date. The dealership will verify that your vehicle meets the settlement criteria—model year, mileage, and time since purchase.
If your vehicle qualifies, the dealership will diagnose the inverter to confirm whether it is faulty. If the inverter is defective, Toyota will repair or replace it at no cost to you. If the inverter is functioning normally, the dealership may charge you for the diagnostic visit, though some dealerships waive this fee. The repair itself typically takes one to two days, depending on dealership workload and parts availability.
You do not need to provide any settlement documentation or court papers. The dealership has access to the settlement terms through Toyota's internal systems and can look up your vehicle by VIN (vehicle identification number) to confirm coverage.
How to Verify Your Vehicle's may be able to access
The easiest way to verify may be able to access is to call or visit a Toyota dealership directly. Provide your vehicle's VIN, which appears on your registration, insurance card, or the driver's side dashboard. The dealership can check whether your Prius falls within the settlement coverage in minutes.
You can also check your vehicle's purchase date and current mileage yourself before contacting the dealership. Write down the model year, the date you or the original owner purchased the vehicle, and the current mileage. If all three fall within the settlement window—2010–2015, within 10 years of purchase, and under 150,000 miles—your vehicle is likely covered.
Do not rely on third-party websites claiming to check settlement status for you. Go directly to the dealership or call Toyota customer service at 1-800-331-4331 to confirm coverage.
What the Settlement Does and Does Not Cover
The settlement covers the inverter power module itself and the labor required to repair or replace it. If the inverter is faulty, Toyota pays for the part and the dealership's work. You will not receive a refund for previous repairs you paid for out of pocket, and the settlement does not cover other vehicle problems unrelated to the inverter.
The settlement also does not cover damage caused by accidents, neglect, or unauthorized repairs. If your inverter failed because of a collision or because someone other than a Toyota dealership worked on the hybrid system, the settlement may not explore. The dealership will determine whether the failure is covered based on the condition of the inverter and the vehicle's service history.
Once the inverter is repaired or replaced under the settlement, the repair itself is covered for the remainder of the settlement period or your vehicle's warranty, whichever is longer. If the new inverter fails within that timeframe, you can return to the dealership for another repair at no cost.
What to Do If Your Dealership Denies Coverage
If a dealership tells you your vehicle is not covered, ask them to explain why in writing. Common reasons include the vehicle exceeding 150,000 miles, being outside the model year range, or the purchase date being more than 10 years ago. Request that they check your VIN in Toyota's settlement system to confirm.
If you believe the dealership made an error, contact Toyota customer service at 1-800-331-4331 and provide your VIN and purchase date. You can also reach out to the settlement administrator or consult the original court settlement documents, which are public record and available through the federal court in California that approved the settlement.
If you paid for an inverter repair before the settlement was approved and your vehicle would have been covered, you may be able to file a claim for reimbursement. The settlement typically includes a claims process for owners who paid out of pocket. Contact Toyota customer service or the settlement administrator for details on how to submit a reimbursement claim.
Timeline and Current Status of the Settlement
The settlement was approved by the court in 2023 and is currently active. Toyota is honoring repair requests at dealerships nationwide. There is no important date to have your repair performed, as long as your vehicle remains within the 10-year and 150,000-mile window from original purchase.
However, the coverage window is fixed to your vehicle's purchase date and mileage, not to the current date. This means a 2010 Prius purchased in 2010 will eventually age out of coverage in 2020, regardless of when you attempt to have the repair done. If you suspect your inverter is failing, scheduling a dealership visit sooner rather than later ensures you remain within the coverage period.
Frequently Asked Questions
Can I get the repair done at an independent mechanic instead of a Toyota dealership?
No. The settlement requires that repairs be performed by an authorized Toyota dealership. Independent mechanics cannot access Toyota's settlement system or order parts under the settlement terms. If you have the repair done elsewhere, you will likely have to pay out of pocket.
What if I bought my Prius used and I'm not the original owner?
You are still covered by the settlement. The coverage is tied to the vehicle, not the owner. Bring your current registration and the dealership can verify the original purchase date using the VIN. You do not need to provide proof that you are the original owner.
Will the repair affect my vehicle's warranty or resale value?
The repair itself does not void any remaining warranty. A replaced inverter is covered under Toyota's warranty for the remainder of the settlement period. Repairing a known defect may actually help resale value by addressing a known issue. Disclose the repair to potential buyers if you sell the vehicle.
How long does the inverter repair take?
The repair typically takes one to two business days. Some dealerships can complete it faster if parts are in stock. Call ahead to ask about wait times and whether the dealership has the inverter in inventory before you bring your vehicle in.
What symptoms indicate my inverter is failing?
Common signs include the vehicle not starting, the hybrid system shutting down while driving, warning lights on the dashboard related to the hybrid system, or a loss of power when accelerating. If you experience any of these symptoms, take your vehicle to a dealership for diagnosis. The dealership can determine whether the inverter is faulty or whether the problem is something else.
