Is Your Tesla Powerwall on the Recall List?
Is Your Tesla Powerwall on the Recall List? The 10,500-Unit Safety Alert Explained
A reader from Leeds sent me a photo of his garage wall at 9pm on a Tuesday, with the message: "Just saw the recall headlines. Is my Powerwall going to catch fire while we sleep?" If you own a Powerwall 2, I'd guess something similar has crossed your mind.So let's cut through the noise and go through exactly what the recall covers, whether your unit is on the list, and what actually happens next if it is — including the bit some of the cheerier coverage has glossed over — in plain English, no panic required.
The 30-second version
- What was recalled: certain Powerwall 2 units — not Powerwall 3, not Powerwall+, not Powerwall 1.
- The window: units sold roughly November 2020 – December 2022, hit by a faulty batch of cells from a third-party supplier.
- The fix: Tesla remotely drains affected units to make them safe, then replaces them free of charge — some owners are even receiving a Powerwall 3. Be aware some owners report the wait has run to a few months.
- The check: keep your system online and look for a recall notification in the Tesla app. That's the definitive answer,and it takes two minutes.
- UK angle:it wasn't a UK-issued recall, but some UK units fall inside the window — so check anyway.
What exactly is the 10,500-unit recall?
In mid-November 2025, the US Consumer Product Safety Commission (CPSC) published recall 26-092, covering about 10,500 Powerwall 2 AC battery systems sold between November 2020 and December 2022, at around $8,000 each. It followed a similar Australian notice in September 2025 covering units sold from 1 November 2020 to mid-2022. The hazard wording is blunt: certain lithium-ion cells can cause the unit to stop working during normal use, which can lead to overheating, smoke or flame.
Those incident numbers come straight from the CPSC notice: 22 reports of overheating, including six involving smoke and five involving fire, all causing only minor property damage, with no injuries. Scary headlines, yes — but also a reminder of how rare the fault is, even within the recalled batch.
| Detail | What the notices say |
|---|---|
| Product | Tesla Powerwall 2 AC battery system (model name printed on the side nameplate) |
| Sales window | Nov 2020 – Dec 2022 (US); 1 Nov 2020 – mid-2022 (Australia) |
| Cause | Faulty battery-cell batch from a third-party supplier, risking overheating |
| US recall number | CPSC 26-092, announced 13 November 2025 |
| Remedy | Free replacement; affected online units remotely discharged first to make them safe |
| Not affected | Powerwall 3, Powerwall+, Powerwall 1, and Powerwall 2 units outside the batch |
What actually went wrong inside the battery?
Every home battery is thousands of small lithium-ion cells working as a team. Tesla traced this recall to a bad batch of cells from a third-party supplier — a manufacturing defect, not a design flaw in the Powerwall as a whole. A dodgy cell can develop an internal short circuit, which generates heat. If the heat builds faster than the battery management system can shut things down, you get the escalation ladder below. In the recalled units, Tesla's software now spots the early signs and safely drains the battery before it gets anywhere near the top rungs.

This is also why the wider UK rulebook has tightened so much — our guide onsolar battery fire safetycovers the new PAS 63100 and BS 7671 rules,including why batteries can no longer go in lofts or on escape routes.
How to check if YOUR Powerwall is on the recall list
Tesla is identifying affected units individually rather than publishing a giant serial-number list,so the app is your source of truth.Here's the five-minute check I'd do:

Rough first filter only — the Tesla app gives the definitive answer.
Does the recall affect UK Powerwall owners?
Short answer: it wasn't a UK-issued recall,but yes,some UK units sit inside the affected window.The notices came from Australia and the US,and the UK's Office for Product Safety Standards hasn't published its own Powerwall alert — you can double-check that yourself any time on theGOV.UK product safety alerts and recalls service,which is worth bookmarking for any product in your home,batteries or otherwise.
🇬🇧 The UK position,honestly
Because the faulty cells shipped in a specific production batch,a small number of UK Powerwall 2 installs fall inside it — and Tesla's replacement programme applies to affected units regardless of country. The Powerwall 2 is now discontinued in the UK, so nobody is selling new affected stock, and the Powerwall 3 is not part of the recall at all. If you're curious what a swap or upgrade looks like,ourPowerwall 3 vs Powerwall 2 comparisonbreaks it down.
Official recall guidance for consumers is also summarised onGOV.UK's product recalls and alerts page, and the original US notice sits on the CPSC website.
On the list? Here's exactly what happens next
First,don't yank the isolator and don't start unscrewing anything — a home battery is not a DIY project.The process Tesla has been running since late 2025 is refreshingly simple in principle:
⏳ The honest bit:replacements haven't all been quick
It would be misleading to say this has gone smoothly for everyone. Owner reports through mid-2026 describe waits stretching to two or three months between a unit being remotely discharged and the physical replacement actually happening — during which the household has no battery backup at all. In July 2026, a Florida owner's case(reported via Reddit and covered by The Cool Down)described Tesla leavingbothof their home batteries drained for months,even though only one was technically part of the recall,before support confirmed both would be replaced.A separate class-action lawsuit filed in Florida,reported by Electrek,alleges the discharge-then-wait process has been "slow, burdensome, and incomplete" for some customers.
None of that changes the core advice — keep your system online,check the app,and you'll get a free replacement — but if you're relying on your Powerwall for backup power during outages,it's worth going into this with realistic expectations about timing rather than assuming next-day service.
Powerwall 2 vs Powerwall 3: the quick comparison
If your Powerwall 2 is being replaced, or you're weighing up an upgrade yourself,here's the honest side-by-side (and our full Tesla Powerwall UK cost guide for 2026 has the latest installed prices, including Octopus's published £7,499 standalone figure):
| Powerwall 2(recalled batch) | Powerwall 3(current) | |
|---|---|---|
| Usable capacity | 13.5 kWh | 13.5 kWh |
| Continuous output | ~5 kW | 11.5 kW |
| Solar inverter | Separate unit needed | Built in |
| Round-trip efficiency | ~90% | 97.5% |
| Warranty | 10 years | 10 years(70%capacity) |
| UK status 2026 | Discontinued | £7,499–£10,500 installed,0%VAT to 31 Mar 2027 |
Should this put you off home batteries altogether?
Honestly?No.Tesla has shipped well over a million Powerwalls worldwide,and a faulty batch of roughly 10,500 units — caught and recalled at no cost to owners — is,at its core,a story of the safety systemworking,not failing.The replacement rollout has clearly been bumpier for some owners than Tesla's own messaging suggests, which is worth knowing going in, but it doesn't change the underlying fact that a defect was caught before it caused serious harm.Compare that with the cheap,unbranded battery packs that dominate theofficial recall listsyear after year.The lesson isn't "batteries are dangerous"; it's"buy branded kit, installed by certified professionals, and go in with realistic expectations about support timelines"— which is exactly whatMCS certificationexists for.If you're comparing options right now, our round-up of the best solar batteries in the UK for 2026 and the hub on home battery storage are the places to start, and if you already have solar, adding a battery to existing panels is simpler than most people think. There's even money to be made once you're set up — see how owners get paid by Tesla, Octopus or Axle to share their battery.

Frequently asked questions
How do I check if my Tesla Powerwall is on the recall list?
Keep your Powerwall 2 online and check the Tesla app for a recall notification — Tesla flags affected units individually rather than publishing a serial list.The recalled batch was sold between November 2020 and December 2022,and your model and serial number are on the nameplate on the side of the unit(and in the app).If anything's unclear, contact Tesla support or your installer with the serial to hand.
Does the Powerwall 2 recall affect UK homes?
The formal notices came from Australia and the US rather than the UK regulator, but a small number of UK Powerwall 2 units fall inside the affected production window. Tesla's free-replacement programme applies to affected units regardless of country.Check the Tesla app,and you can monitor the GOV.UK product safety alerts service for any UK-side notices.
What happens if my Powerwall is recalled — and what will it cost me?
The replacement itself is free — Tesla remotely discharges affected online units to make them safe,then replaces the system at no cost,and through 2026 many owners report their Powerwall 2 being swapped for a newer Powerwall 3.What isn't guaranteed is speed: some owners have reported waits of two to three months for the physical swap, and a Florida class-action lawsuit has challenged how that waiting period has been handled, so budget for some inconvenience even though there's no bill at the end of it.
Bottom line:a two-minute app check tonight buys you real peace of mind,even if the physical swap itself takes a little patience.Do the check,keep the paperwork,and let your battery get on with quietly shrinking your energy bills.
