Automobile warranties have been in place for over 100 years. Originally, auto warranties were used as a way for the manufacturer to build trust in their products and provide confidence that they would stand behind the vehicle and its durability. Today, buyers look at a warranty as the reason they are purchasing a more costly new vehicle instead of a used car, truck, or SUV. They see the warranty as a safety blanket that prevents them from facing costly repairs for the term of the warranty.

Everyone has heard another person refer to a car as a lemon, mostly because it has a long list of issues. But for the term lemon to be applied in a legal sense in California, the vehicle must suffer from a single, plaguing problem that the manufacturer cannot seem to correct.

The History Of The Lemon Law In California

Originally known as the Song-Beverly Consumer Warranty Act, which was passed into law in March of 1971, the term today is the California Lemon Law. The goal of the law was to provide consumers in California with a level of support as well as resolution when a manufacturer was unable to repair an issue and honor their express warranty. The Lemon Law established an obligation to replace or refund consumers for any item that they were unable to fix under the terms of the warranty. The law from 1971 remains the foundation of the current Lemon Law we use today. It still provides consumers with the protection they need if they have issues with a product and the manufacturer cannot or will not make it right. There have been a few updates to the law over the years, such as defining what a reasonable repair effort would be, and most recently, an update to the Statue of Limitations.

Beyond the qualifications and restrictions mentioned above, the Statue of Limitations is another item that qualifies your ability to file a claim. Updated just in 2025, it limits the time a Lemon Law claim or lawsuit can be filed, as it directly relates to the warranty and delivery date. If you are considering a Toyota Prius inverter failure lemon law lawsuit, call us at Guardian Lemon Law. We can help you get this annoying matter resolved.

The Time Limit To File A Lemon Lawsuit In The State of California

There are two different limitations for making a Lemon Law Claim or filing a lawsuit. The first date is one year from the expiration of the original factory warranty or certified pre-owned warranty. The second date is six years from the date the vehicle was delivered to you. The time limit that applies in your case will be the earliest of the two dates. Any action must be filed prior to that date. Once the date has passed, no claim or suit can be filed.

The Symptoms And Owner Experiences Of The 2010-2015 Toyota Prius Issues

As an owner of a 2010-2015 Toyota Prius, which is known as the Gen 3 units, you need to understand the indications of the alarmingly common issues related to power loss and electric motor failures. The problems are often attributed to failure or issues with the IPM or the Intelligent Power Module that is within the inverter. The verdict is that in higher operating temperatures, the transistor is damaged, causing the power loss of the Prius. In other cases, technicians have determined that corrosion and thermal stress, or overheating, occur over an extended period of time. Thermal cycling increases the potential for corrosion and system failure. The final culprit that could be to blame for the loss of power in your Prius is the failure of the inverter coolant pump that is tasked with heat dissipation. In general, all of the issues are related to overheating of the inverter or the IPM, which can result in motor failure or loss of power.

As a Prius owner and driver, you need to watch for these common indications of trouble with heat and the possible damage to integral components that could cause your Prius to suddenly lose power, stall, function in a sluggish manner, or become difficult and hazardous to drive. Watch for:

  • Warning lights and messages, such as the check hybrid system message, check engine light, or ABS/slip icon, are illuminated
  • Sudden decrease in power, failure to accelerate, stalling in traffic
  • The car shifts into limp mode, which is a safety mode that reduces and restricts speed when the inverter fails
  • A burning odor is coming from the vehicle
  • Displayed diagnostic codes that include P0A94, P0A08/P0A09,P3224E, P0A1A,P0A93
