The recalled detectors can fail to alert consumers of a fire, posing a risk of serious injury or death from smoke inhalation or burns.
The recalled detectors can malfunction and fail to alert consumers of a fire or carbon monoxide (CO) leak, posing a risk of smoke inhalation, carbon monoxide poisoning or death.
After alerting consumers to the presence of natural gas or carbon monoxide, the recalled alarm can go into sleep mode when the alert lasts less than four minutes. During this time, the alarms can fail to detect and alert consumers to a new incidence of natural gas or carbon monoxide, posing a risk of carbon monoxide poisoning.
The detectors can fail to activate, posing a risk that consumers will not be alerted to a fire.

The detectors can fail to alert consumers to the presence of hazardous smoke and fire.
The alarms can fail to alert consumers to the presence of a hazardous level of carbon monoxide, posing a risk of carbon monoxide poisoning or death. Carbon monoxide (CO) is an odorless, colorless, poisonous gas.

The smoke alarm and the combination smoke/carbon monoxide (CO) alarm can fail to alert consumers to a fire.
The alarm can fail to continue to chirp when it reaches its 7-year end of life if the batteries are replaced, leading consumers to believe it is still working. This poses a risk of consumers not being alerted to a fire or CO incident in their home.

The alarms could fail to alert consumers of a fire or a CO incident following a power outage.
Nest Labs
Activity near the product during a fire can prevent the alarm from immediately sounding when the Nest Wave feature is enabled.
When the CO detectors reach the end of their useful life, they should send a signal to make a sound in the home alarm panel alerting consumers it is time to replace them and a signal to ADT's alarm monitoring center. Some of the detectors were not wired properly to the ADT alarm system, resulting in the sound not going off in the home alarm panel and no signal to the ADT alarm monitoring center at the end of its useful life. Not replacing a CO detector at the end its useful life poses a CO poisoning hazard to consumers.
The recalled alarms can sound a "double chirp"/fault alarm in the presence of CO, prior to going into full alarm. Upon hearing a double chirp, the Owner's Manual instructions recommend a consumer take the alarm out of service, which could expose consumers to hazardous levels of CO and suffer injury or death.
