Mueller UltraPot Pressure Cooker Lawsuit Update: Injuries, Recall Status, and Legal Options

A Virginia woman has sued Amazon.com, Inc. over a Mueller Electric Pressure Cooker sold as the Mueller UltraPot, model ML100A-M01. She says its lid opened while the unit was still pressurized. Hot contents escaped and burned her in February 2024. She blames a defective interlock that should have kept the lid locked under pressure. That, she says, violated a safety standard for pressure cookers. This case is a single, individual lawsuit against Amazon rather than a class action or multidistrict case. It was opened January 15, 2026, in Seattle federal court, and no recall of the Mueller UltraPot has been announced so far.

March 27, 2026: Amazon Substitutes Counsel in the Case

Amazon substituted its counsel in Nguyen v. Amazon.com Inc. on March 27, 2026. It added two Morrison & Foerster LLP attorneys in place of an outgoing Perkins Coie LLP attorney, according to the case docket. The switch is a routine court filing. It does not signal a change in the case’s direction, and the underlying claims against Amazon over the pressure cooker’s lid remain pending.

January 15, 2026: Nguyen Files Suit over Pressure Cooker Lid

Chung Thuy Nguyen filed a federal product-liability complaint against Amazon.com, Inc. in the U.S. District Court for the Western District of Washington at Seattle, Case No. 2:26-cv-00136, before Judge James L. Robart [1]. She alleges the lid of a Mueller Electric Pressure Cooker rotated open while the unit remained pressurized on February 17, 2024. Hot contents ejected and caused her burn injuries.

Who May Be Affected?

Anyone who purchased or used a Mueller Electric Pressure Cooker, Model ML100A-M01, through Amazon may match the circumstances alleged in this case. That case involves a burn from the lid opening while the unit remained pressurized. The complaint alleges a defective interlock let the lid open under pressure instead of staying locked until fully released. This violated UL 136, an industry safety standard for pressure cookers, and let hot contents eject onto the user. The Judicial Panel on Multidistrict Litigation‘s pending-docket list, dated September 1, 2026, names no pressure-cooker case. Only an individual legal review can confirm whether a specific case matches the circumstances described above.

Reported Injuries or Damages

The complaint alleges Nguyen suffered serious and substantial burn injuries. Hot contents escaped the pressure cooker after its lid rotated open while pressurized. These are allegations from the complaint, not proven facts or a court finding. Independent research shows pressure-cooker burns can be severe. A burn-center study of cases from 2016 to 2024 found most pressure-cooker burns were second-degree. These burns most often affected the head, neck or chest [2]. A separate national estimate comes from the Consumer Product Safety Commission’s injury-surveillance database. It found about 28,337 pressure-cooker injuries treated nationwide from 2003 to 2019, roughly 1,667 a year [3]. Neither study focuses on the Mueller UltraPot.

Evidence to Preserve

Keep these items on hand in case a legal claim over an injury from a Mueller UltraPot pressure cooker becomes possible:

• The pressure cooker itself, including its lid, sealing ring, gasket and locking pin mechanism
• The original purchase receipt, with the order number
• The model and serial number from the unit
• Photographs or video of the product and the injury
• Medical records documenting treatment
• Any communications with Amazon or Mueller customer service

The product’s own manual asks owners to keep this same documentation on hand when reporting a defect. It also states a two-year warranty from the purchase date for the original buyer [4].

Filing Deadlines

Deadlines for filing a product-liability claim come from state law, not from this lawsuit. A missed deadline can defeat an otherwise strong claim. How much time a person has depends on where they live and when the injury and its diagnosis happened. Some states start the clock at diagnosis rather than at the date of the incident. Anyone who was burned by a Mueller UltraPot and is considering a claim should speak with a lawyer promptly. This helps avoid missing a deadline.

Potential Compensation

A lawsuit like this one can seek damages for medical expenses, lost income, and pain and suffering. In a case with visible scarring, it can also seek compensation for disfigurement. These categories come from the complaint’s own request for damages. Compensation amounts vary by case. Past results do not guarantee future outcomes. A lawyer can explain what potential compensation might look like for a claim.
