General Motors announced that battery production for the Chevy Bolt EV is once again underway. Battery production resumed on Monday, the automaker said, and outlined a course of action to “ensure that customers can safely and confidently drive, charge, and park the Chevy Bolt EV and EUV.”
Over the past twelve months, the Bolt EV has had three recalls related to battery issues that have caused combustion in some instances. During the July recall, the second related to battery problems, GM announced that “the simultaneous presence of two rare manufacturing defects in the same battery cell” caused an increased risk of battery fires. The recall affected around 69,000 cars worldwide.
GM then doubled down on the recall in late August, announcing that it had temporarily halted production of the Bolt altogether. GM spokesman Daniel Flores commented:
“We will not resume repairs or restart production until we are confident LG is producing defect-free products for us.”
As of now, manufacturing of the Bolt EV has not resumed, only the production of the battery cells that the vehicle utilizes.
The recalls set GM back around $1.8 billion so far this year and led to a widespread case of paranoia among those who saw the vehicles on the road. A parking lot in San Francisco actually prohibited Bolt EVs from parking at their facility due to the battery issues.
Now, GM has announced that production has resumed for Bolt EV batteries. Due to an updated manufacturing process and new advanced diagnostics software from GM, there is now confidence from the Detroit-based automaker that the worst of the issues are now behind them. “We’re grateful for the patience of owners and dealers as we work to advance solutions to this recall,” GM Executive VP of Global Product Development, Purchasing and Supply Chain, Doug Parks, said. “Resuming battery module production is a first step and we’ll continue to work aggressively with LG to obtain additional battery supply. In addition, we’re optimistic a new advanced diagnostic software will provide more convenience for our customers.”
The Bolt EV utilizes cells from battery supplier LG, which operates cell production plants in Holland and Michigan. Both facilities have resumed production and replacement battery modules will be shipped to dealers “as soon as mid-October,” the company said. LG has worked with GM to initiate and implement a new plan of attack that will recognize and identify defects in battery cells, providing confidence in the batteries moving forward.
How the Chevy Bolt EV became GM’s 1.8 billion dollar problem
In terms of the replacement process of the affected population, GM said it will “continue to prioritize Chevy Bolt EV and EUV customers whose batteries were manufactured during specific build timeframes where GM believes battery defects appear to be clustered. The company has established a notification process that will inform affected customers when their replacement modules will be available.” The new batteries will include an extended warranty as well: 8-year/100,000-mile limited warranty (8-year/160,000 km limited warranty in Canada).
Additionally, GM will launch a new advanced diagnostic software that will roll out within approximately 60 days. The software will detect specific abnormalities that might indicate a damaged or defective battery in either the Bolt EV or EUV, alerting customers of abnormalities. GM plans to allow owners to return to 100% state of charge once diagnostic processes are completed. For now, the company states that owners should do the following:
- Set the vehicle to a 90 percent state of charge limitation using Target Charge Level mode. Instructions on how to do this are available on chevy.com/boltevrecall. If customers are unable to successfully make these changes or do not feel comfortable making these changes, GM is asking them to visit their dealer to have these adjustments completed.
- Charge the vehicle more frequently and avoid depleting battery below approximately 70 miles (113 km) of remaining range, where possible.
- Continue to park vehicles outside immediately after charging and do not leave vehicles charging indoors overnight.

Elon Musk’s xAI brings 1GW Colossus 2 AI training cluster online
Elon Musk shared his update in a recent post on social media platform X.
xAI has brought its Colossus 2 supercomputer online, making it the first gigawatt-scale AI training cluster in the world, and it’s about to get even bigger in a few months.
Elon Musk shared his update in a recent post on social media platform X.
Colossus 2 goes live
The Colossus 2 supercomputer, together with its predecessor, Colossus 1, are used by xAI to primarily train and refine the company’s Grok large language model. In a post on X, Musk stated that Colossus 2 is already operational, making it the first gigawatt training cluster in the world.
But what’s even more remarkable is that it would be upgraded to 1.5 GW of power in April. Even in its current iteration, however, the Colossus 2 supercomputer already exceeds the peak demand of San Francisco.
Commentary from users of the social media platform highlighted the speed of execution behind the project. Colossus 1 went from site preparation to full operation in 122 days, while Colossus 2 went live by crossing the 1-GW barrier and is targeting a total capacity of roughly 2 GW. This far exceeds the speed of xAI’s primary rivals.
Funding fuels rapid expansion
xAI’s Colossus 2 launch follows xAI’s recently closed, upsized $20 billion Series E funding round, which exceeded its initial $15 billion target. The company said the capital will be used to accelerate infrastructure scaling and AI product development.
The round attracted a broad group of investors, including Valor Equity Partners, Stepstone Group, Fidelity Management & Research Company, Qatar Investment Authority, MGX, and Baron Capital Group. Strategic partners NVIDIA and Cisco also continued their support, helping xAI build what it describes as the world’s largest GPU clusters.
xAI said the funding will accelerate its infrastructure buildout, enable rapid deployment of AI products to billions of users, and support research tied to its mission of understanding the universe. The company noted that its Colossus 1 and 2 systems now represent more than one million H100 GPU equivalents, alongside recent releases including the Grok 4 series, Grok Voice, and Grok Imagine. Training is also already underway for its next flagship model, Grok 5.

Tesla AI5 chip nears completion, Elon Musk teases 9-month development cadence
The Tesla CEO shared his recent insights in a post on social media platform X.
Tesla’s next-generation AI5 chip is nearly complete, and work on its successor is already underway, as per a recent update from Elon Musk.
The Tesla CEO shared his recent insights in a post on social media platform X.
Musk details AI chip roadmap
In his post, Elon Musk stated that Tesla’s AI5 chip design is “almost done,” while AI6 has already entered early development. Musk added that Tesla plans to continue iterating rapidly, with AI7, AI8, AI9, and future generations targeting a nine-month design cycle.
He also noted that Tesla’s in-house chips could become the highest-volume AI processors in the world. Musk framed his update as a recruiting message, encouraging engineers to join Tesla’s AI and chip development teams.
Tesla community member Herbert Ong highlighted the strategic importance of the timeline, noting that faster chip cycles enable quicker learning, faster iteration, and a compounding advantage in AI and autonomy that becomes increasingly difficult for competitors to close.
AI5 manufacturing takes shape
Musk’s comments align with earlier reporting on AI5’s production plans. In December, it was reported that Samsung is preparing to manufacture Tesla’s AI5 chip, accelerating hiring for experienced engineers to support U.S. production and address complex foundry challenges.
Samsung is one of two suppliers selected for AI5, alongside TSMC. The companies are expected to produce different versions of the AI5 chip, with TSMC reportedly using a 3nm process and Samsung using a 2nm process.
Musk has previously stated that while different foundries translate chip designs into physical silicon in different ways, the goal is for both versions of the Tesla AI5 chip to operate identically. AI5 will succeed Tesla’s current AI4 hardware, formerly known as Hardware 4, and is expected to support the company’s Full Self-Driving system as well as other AI-driven efforts, including Optimus.

Tesla Model Y and Model 3 named safest vehicles tested by ANCAP in 2025
According to ANCAP in a press release, the Tesla Model Y achieved the highest overall weighted score of any vehicle assessed in 2025.
The Tesla Model Y recorded the highest overall safety score of any vehicle tested by ANCAP in 2025. The Tesla Model 3 also delivered strong results, reinforcing the automaker’s safety leadership in Australia and New Zealand.
According to ANCAP in a press release, the Tesla Model Y achieved the highest overall weighted score of any vehicle assessed in 2025. ANCAP’s 2025 tests evaluated vehicles across four key pillars: Adult Occupant Protection, Child Occupant Protection, Vulnerable Road User Protection, and Safety Assist technologies.
The Model Y posted consistently strong results in all four categories, distinguishing itself through a system-based safety approach that combines structural crash protection with advanced driver-assistance features such as autonomous emergency braking, lane support, and driver monitoring.
This marked the second time the Model Y has topped ANCAP’s annual safety rankings. The Model Y’s previous version was also ANCAP’s top performer in 2022.
The Tesla Model 3 also delivered a strong performance in ANCAP’s 2025 tests, contributing to Tesla’s broader safety presence across segments. Similar to the Model Y, the Model 3 also earned impressive scores across the ANCAP’s four pillars. This made the vehicle the top performer in the Medium Car category.
ANCAP Chief Executive Officer Carla Hoorweg stated that the results highlight a growing industry shift toward integrated safety design, with improvements in technologies such as autonomous emergency braking and lane support translating into meaningful real-world protection.
“ANCAP’s testing continues to reinforce a clear message: the safest vehicles are those designed with safety as a system, not a checklist. The top performers this year delivered consistent results across physical crash protection, crash avoidance and vulnerable road user safety, rather than relying on strength in a single area.
“We are also seeing increasing alignment between ANCAP’s test requirements and the safety technologies that genuinely matter on Australian and New Zealand roads. Improvements in autonomous emergency braking, lane support, and driver monitoring systems are translating into more robust protection,” Hoorweg said.
