Honolulu homeowners who bought Tesla Powerwall 2 units for peace of mind are instead getting a crash course in patience. After federal regulators moved last week on a safety issue, locals are still waiting to find out when Tesla will actually swap out recalled batteries.
The U.S. Consumer Product Safety Commission flagged roughly 10,500 Powerwall 2 systems over a battery cell defect that can cause overheating, and Tesla has remotely discharged affected units to remove the immediate fire risk. That means some households are temporarily without backup power and cannot store daytime solar for night-time use, a change that can nudge already-high electric bills even higher.
What the recall covers
The recall applies to about 10,500 Powerwall 2 AC battery systems sold from November 2020 through December 2022. The U.S. Consumer Product Safety Commission says it has received 22 reports of overheating, including six reports of smoking and five fires that caused minor property damage. No injuries have been reported, and affected units that are online have been remotely discharged until replacement batteries are installed.
How Tesla plans to replace affected units
Tesla says it has limited the charge on affected Powerwall 2 systems and will replace those units at no cost to customers, although the company has not given a timeline for completing all the swaps. According to Reuters, Tesla will notify affected customers through the Tesla app, and either Tesla or certified installers will contact homeowners by email or phone to schedule removal and installation visits.
Local impact and city response
Honolulu readers told the Star-Advertiser that some Powerwalls in the islands were discharged weeks ago, and the paper’s Kokua Line column notes that if there is no recall banner in the Tesla app, the unit is not part of the recall list. The column also quoted a Department of Parks and Recreation spokesperson urging residents to report city property problems through the 311 app, and reported that crews repaired floodlights at Kamilo Iki Neighborhood Park, 1109 Lunalilo Home Road. The full Q&A is in the Star-Advertiser's Kokua Line.
What Powerwall owners should do now
Powerwall owners are advised to make sure their system is online and to check the Tesla app for a recall banner. Customers should contact their original installer or Tesla support at [email protected] or 877-961-7652 to arrange service. Per CPSC, Tesla will replace affected units free of charge and has remotely discharged online systems to reduce the immediate hazard. Homeowners should keep records of any extra electricity charges while their battery is disabled so they can raise those costs with Tesla or their installer when work is scheduled.
Why this matters
The recall highlights ongoing questions about battery cell suppliers and the long-term durability of home energy storage systems as more Hawai‘i households add solar plus batteries. Tesla faced a similar recall in Australia in September, where many affected units were also discharged remotely and replacements scheduled, according to TechCrunch. For now, Honolulu homeowners with Powerwall 2 units should be prepared for direct contact from Tesla or their installer and plan around a temporary loss of stored power.
