Tesla has issued a recall notice for its fully integrated Powerwall 2 AC battery energy storage system and initiated a replacement program for roughly 10,500 affected units in the United States (US).
The US Consumer Product Safety Commission reported that Tesla has received 22 reports of overheating, including six instances of smoking and five cases of fire resulting in minor property damage. No injuries have been reported.
Tesla said that the recall is due to a third-party battery cell defect, without naming the supplier.
The US recall comes on the heels of a similar nationwide recall in Australia initiated in September.

Lithium-ion batteries have had “thermal Runaways” in both Automobiles and on Powerwall home installed batteries because of its chemistry. An alternative Lithium Ferrous Phosphate chemistry does NOT have this problem, yet Tesla has continued to use Lithium-ion battery chemistries unless governments intervein like China did on all the vehicles made and sold in its country. When I installed my rooftop solar, I was offered power walls with lithium-ion chemistry and I said NO. When I had a garage fire and my Tesla Solar Glass Roof above it was compromised, the first thing Tesla did was check to see if my system had started the fire not how much it would cost my insurance to replace and repair it. They told me the whole roof would have to be replaced over the entire home. They first suspected the lithium-ion batteries even back in March of 2023 and that gave me a clue that they could be a problem. They also would not replace my solar roof without my purchasing the lithium-ion powerwall(s) with it that the insurance company would not cover since I did not have them originally. I opted for a 50- year conventional roof and Enphase inverters on 20-420-watt solar panels instead. Battery ready, my system is just waiting for “SAFE” batteries to attach to the side of my home.
