Ruskey Family Files Navien Tankless Water Heater Carbon Monoxide Lawsuit

• Three teenage children have filed a lawsuit following the carbon monoxide poisoning deaths of their parents, John and Kristen Ruskey.
• The suit targets Navien, Inc. and Kyung Dong Navien Co., alleging a defective tankless water heater caused the CO leak.
• Homeowners Ben and Robin Korman are also sued for premises liability, as a carbon monoxide detector in their Cambria home was reportedly disconnected.
• The plaintiffs claim Navien was aware of product issues, citing a 2011 recall of 13,000 units and at least nine other related deaths since 2019.
• The Ruskeys died on February 8, 2026, after staying overnight at the Korman residence in Cambria, California.

The lawsuit alleges that Navien, Inc. and Kyung Dong Navien Co. had prior knowledge of potential hazards associated with their tankless water heaters, evidenced by a 2011 recall and multiple reported fatalities.

On February 8, 2026, John and Kristen Ruskey tragically died from carbon monoxide poisoning while guests at an opulent oceanfront residence in Cambria, California. The couple, known as agricultural innovators for their work with specialty crops like caviar lime and dragon fruit and their founding of Frinj Coffee, had traveled to the coastal town to attend a birthday celebration. John, aged 53, and Kristen, 49, were invited to spend the night at the Korman home, a sprawling 5,548-square-foot property valued at over $6.6 million, after an event attended by 50 to 60 guests.

During the early morning hours, Kristen Ruskey placed a 911 call at 4:34 a.m., reporting her husband was in severe distress. Other guests at the residence reportedly heard Jay Ruskey screaming, and he exhibited symptoms such as loss of bowel control while in bed. These signs are consistent with acute carbon monoxide poisoning, which can manifest as headaches, nausea, confusion, motor control loss, seizures, and unconsciousness as oxygen is displaced in the bloodstream. Medics responded, and Kristen informed them that John had consumed psychedelic mushrooms and was experiencing a difficult trip. Despite a recommendation for hospital transport, John declined, and the couple returned to their guest bedroom.

Hours later, around 9:30 a.m., guests discovered Kristen Ruskey unresponsive on the laundry room floor and Jay Ruskey deceased in the bed. The San Luis Obispo County Sheriff’s Office later confirmed the causes of death, ruling them accidental. John Ruskey's death was attributed to the toxic effects of carbon monoxide, while Kristen Ruskey's death was caused by the toxic effects of carbon monoxide and ethanol. The deaths sent shockwaves through the small community of Cambria, a scenic area south of Big Sur, highlighting the severe consequences of John Kristen Ruskey CO poisoning.

The three teenage children of John and Kristen Ruskey have initiated a lawsuit, alleging that both the manufacturer of a tankless water heater and the homeowners bear responsibility for their parents' untimely deaths. The legal action, focusing on a Navien tankless water heater carbon monoxide lawsuit, names Navien, Inc. and Kyung Dong Navien Co. as defendants under product liability claims. The plaintiffs contend that a defective Navien tankless water heater and its associated exhaust venting system permitted carbon monoxide to leak from an adjacent laundry room directly into the guest bedroom where the Ruskeys were staying, forming the basis of the Ruskey family Navien product liability claim.

Furthermore, the lawsuit extends to homeowners Ben and Robin Korman, asserting premises liability. The Ruskey family's complaint states that the Korman residence lacked a functional carbon monoxide detector, a critical safety device. Investigators later found a combination carbon monoxide/smoke detector in the couple's room, but it was reportedly disconnected, contributing to the Korman premises liability Cambria aspect of the case. The children are seeking damages from all named parties, highlighting the dual nature of the alleged negligence—both in product design and maintenance, and in ensuring a safe environment for guests.

Central to the product liability claim against Navien, Inc. and Kyung Dong Navien Co. is the assertion that the manufacturer had long-standing knowledge of significant safety issues with its tankless water heaters. The lawsuit alleges that Navien, Inc. and Kyung Dong Navien Co. had prior knowledge of potential hazards associated with their tankless water heaters, evidenced by a 2011 recall and multiple reported fatalities. The plaintiffs point to a history of problems, including a substantial Navien water heater recall 2011 involving 13,000 units. Moreover, the plaintiffs allege that since 2019, at least nine fatalities, both domestically and internationally, have been linked to these products, underscoring a pattern of alleged defects. The children's complaint describes how the water heater, under the demand of numerous overnight guests, repeatedly cycled, discharging carbon monoxide through a "failed subject venting system" into the laundry room and subsequently into the guest bedroom.

This case, involving the Kyung Dong Navien Co lawsuit, sets a significant precedent for product liability and premises liability law. It underscores the severe consequences when manufacturers allegedly fail to address known product hazards and when property owners neglect their duty to provide a safe environment, particularly concerning carbon monoxide detection and appliance maintenance. The Ruskey children emphasize the profound loss they experienced, describing how their "world crumbled" on February 8, 2026, losing "two committed parents and a lifetime of love, support, guidance and comfort." The legal proceedings aim to hold accountable those responsible for the tragic California carbon monoxide death of John and Kristen Ruskey.

This case serves as a critical precedent for product liability attorneys demonstrating manufacturer negligence through a history of product defects and recalls, and for premises liability attorneys regarding the duty of care for guest safety, particularly concerning carbon monoxide detection and appliance maintenance. Lawyers should advise clients on the severe consequences of failing to address known product hazards and ensure safe premises.
