Tesla Recalled the Powerwall 2 for Fire Risk. Check Yours This Week.

If there is a Tesla Powerwall 2 on your wall, take five minutes this week and confirm whether it is part of the federal recall. The recall is months old now, which is exactly why this article exists: the first wave of headlines has passed, replacements are still rolling out, and plenty of owners either never heard about it or assumed their unit was fine because nothing seemed wrong. Nothing seeming wrong is not the test.

What happened, from the official record

On November 13, 2025, Tesla recalled about 10,500 Powerwall 2 AC battery systems in the United States, in cooperation with the Consumer Product Safety Commission. The units were sold from November 2020 through December 2022, through Tesla directly and through certified installers, at around 8,000 dollars each. The hazard, in the CPSC’s description, is that lithium-ion cells in certain units can fail during normal use, which can lead to overheating and, in some cases, smoke or fire.

At the time of the recall, Tesla had received 22 reports of overheating, including six units that smoked and five that caught fire, causing minor property damage. No injuries have been reported. Tesla attributed the failures to a defect in battery cells from a third-party supplier it did not name, and a similar recall had already run in Australia two months earlier.

Those are the facts as the federal notice states them. Twenty-two failures out of ten and a half thousand units is a low rate, and it is also a fire hazard bolted to the side of a house, which is why the remedy is a full replacement rather than a software note.

How to check your unit

The check runs through the Tesla app, and it requires your Powerwall to be online.

First, confirm the system is actually connected. A Powerwall that has been offline for months cannot receive the recall notification, and, more importantly, cannot receive the protective measure described below. If your installer set the system up years ago and you have never opened the app, this is the week to sort out your login.

Second, open the Tesla app and look for a recall notification for your unit. Affected owners are notified there directly.

Third, if you find nothing but want certainty, contact Tesla’s Powerwall support directly at powerwallsupportna@tesla.com or 877-961-7652 with your unit’s serial number, which is printed on the nameplate on the side of the unit.

The replacement itself is free, performed by Tesla or a certified installer, and scheduling runs through Tesla.

The part that affects you before the replacement arrives

Here is the detail many owners miss. For affected units that are online, Tesla has remotely discharged the battery, meaning it removed the stored energy, to prevent overheating until the replacement is installed. That is the correct safety move, and it also means something practical: an affected Powerwall may currently be providing little or none of the backup protection you bought it for. If your outage plan assumes that battery, your outage plan has quietly changed until the swap happens. That is worth knowing before a storm rather than during one, and it is a fair thing to press Tesla on when scheduling: ask where you are in the replacement queue and what your unit’s current state actually is.

If your Powerwall is offline, it cannot be remotely protected at all, which makes the connectivity check above more than an administrative chore.

What this does and does not say about home batteries

One recall does not make home batteries dangerous, and it would be dishonest to spin it that way. It is worth understanding one piece of context, though. The Powerwall 2 generation used a nickel-based cell chemistry; much of the industry, including Tesla’s newer products, has since shifted toward lithium iron phosphate, a chemistry with meaningfully more tolerance to overheating. Chemistry is a real, askable question when you shop for storage, and almost nobody asks it. We will take that subject up properly in its own piece; for now, the practical takeaway is simpler: batteries are electrical equipment, equipment sometimes gets recalled, and the owners who register their products, keep them online, and check the official channels are the ones who hear about it when it matters.

The bottom line

Check the app this week. Confirm your unit is online, confirm whether it is affected, and if it is, get in the replacement queue and ask what your backup capacity is in the meantime. The recall system worked the way it is supposed to here: a defect surfaced, the fix is free, and the only owners left exposed are the ones who never got the message. Do not be one of them. The official recall notice lives on the CPSC’s site under recall number 26-092 if you want the source document itself.
