[Updated] Tesla Model 3 batteries will be made by Panasonic, Musk squashes Samsung SDI rumors
Yesterday, news reports said Tesla may be close to a deal to use battery cells from Samsung SDI in its cars. Overnight, Elon Musk tweeted a denial that scotched those reports.
Elon Musk took to twitter to confirm that Tesla Model 3 batteries will be supplied by Panasonic, squashing rumors that the company might be negotiating with Samsung SDI as a competing supplier. Media outlets noted that Japanese-based The Nikkei had reported a large quantity of Samsung SDI batteries had been delivered to Tesla’s development facility in California fueling speculation that Tesla is evaluating Samsung products for possible use at a later time.
A confidential source told Bloomberg that Samsung SDI is in talks with Tesla to provide batteries for its electric cars. That source, who asked to remain unidentified, indicated the two companies were likely to agree on a business arrangement, although nothing has been finalized as of yet. The report sent shares of Samsung SDI up more than 8% in trading yesterday.

The news caused consternation among the Tesla faithful yesterday. Quite a few people posted on the Tesla Motors forum that they expected the batteries in their Model 3 cars to be made by Tesla with its Gigafactory partner Panasonic.
Some if not all of the stock price gains on Samsung SDI from yesterday are likely to evaporate today, as Elon Musk has put the kibosh on the rumors about using Samsung batteries in Tesla automobiles. Panasonic stock traded upwards following the news.
Rumors about Tesla seeking business alliances with other battery companies have been swirling around for months. The rumors heated up when Tesla announced it would use tires from Korean company Hankook for the Model 3. Using the “where there’s smoke there’s fire” analysis, something seems to be going on behind the scenes at Tesla Motors.
If nothing else, Tesla is attempting to avoid the pitfall of placing all its eggs in one basket. Relying exclusively on Panasonic could possibly result in a case of tunnel vision that would keep it from leveraging advances in battery technology by other companies.
Based on Musk’s tweet, Tesla seems firmly wedded to Panasonic as the sole supplier for its automotive batteries. But is there something else going on for the battery storage side of the company? We simply don’t have enough insight into the mind of Musk at present to be able to answer that question.

Tesla recalls 6,197 Cybertrucks for light bar adhesive issue
On October 20, Tesla issued a voluntary recall of the impacted vehicles and has identified 619 warranty claims and just a single field report that is related to the issue.
Tesla has recalled 6,197 Cybertrucks for a light bar adhesive issue that was utilized by Service to install the aftermarket part.
According to the National Highway Traffic Safety Administration (NHTSA), impacted vehicles may have had the light bar “inadvertently attached to the windshield using the incorrect surface primer.”
Tesla identified an issue with the light bar’s adhesion to glass back in February and worked for months to find a solution. In October, the company performed chemical testing as a part of an engineering study and determined the root cause as the BetaPrime primer it utilized, figuring out that it was not the right surface priming material to use for this specific application.
On October 20, Tesla issued a voluntary recall of the impacted vehicles and has identified 619 warranty claims and just a single field report that is related to the issue.
The component is manufactured by a Romanian company called Hella Romania S.R.L., but the issue is not the primer’s quality. Instead, it is simply the fact that it is not the correct adhesive for this specific type of application.
Tesla says there are no reports of injuries or deaths due to this issue, and it will be resolved. In the 473 report that the NHTSA released this morning, Tesla said:
“At no charge to customers, Tesla will inspect the service-installed optional off-road light bar accessory for delamination or damage and if either is present, replace the light bar with a new light bar adhered with tape and a positive mechanical attachment. If no delamination or damage is present, Tesla will retrofit the service-installed optional off-road light bar accessory with a positive mechanical attachment.”
This is the third recall applied to Cybertrucks this year, as one on March 18 highlighted the potential for exterior trim panels to detach while driving, and another earlier this month when the NHTSA said its front parking lights were too bright.
Tesla resolved the first with a free assembly replacement, while the headlight issue was fixed with an Over-the-Air software update earlier this week. Owners said there was a noticeable difference in the brightness of the lights now compared to previously.

Tesla investor Calpers opposes Elon Musk’s 2025 performance award
Musk’s 2025 pay plan will be decided at Tesla’s 2025 Annual Shareholder Meeting, which will be held on November 6 in Giga Texas.
One of the United States’ largest pension funds, the California Public Employees’ Retirement System (Calpers), has stated that it will be voting against Elon Musk’s 2025 Tesla CEO performance award.
Musk’s 2025 pay plan will be decided at Tesla’s 2025 Annual Shareholder Meeting, which will be held on November 6 in Giga Texas. Company executives have stated that the upcoming vote will decide Tesla’s fate in the years to come.
Why Calpers opposes Musk’s 2025 performance award
In a statement shared with Bloomberg News, a Calpers spokesperson criticized the scale of Musk’s proposed deal. Calpers currently holds about 5 million Tesla shares, giving its stance meaningful influence among institutional investors.
“The CEO pay package proposed by Tesla is larger than pay packages for CEOs in comparable companies by many orders of magnitude. It would also further concentrate power in a single shareholder,” the spokesperson stated.
This is not the first time Calpers has opposed a major Musk pay deal. The fund previously voted against a $56 billion package proposed for Musk and criticized the CEO’s 2018 performance-based plan, which was perceived as unrealistic due to its ambitious nature at the time. Musk’s 2018 pay plan was later struck down by a Delaware court, though Tesla is currently appealing the decision.
Musk’s 2025 CEO Performance Award
While Elon Musk’s 2025 performance award will result in him becoming a trillionaire, he would not be able to receive any compensation from Tesla unless aggressive operational and financial targets are met. For Musk to receive his full compensation, for example, he would have to grow Tesla’s market cap from today’s $1.1 trillion to $8.5 trillion, effectively making it the world’s most valuable company by a mile.
Musk has also maintained that his 2025 performance award is not about compensation. It’s about his controlling stake at Tesla. “If I can just get kicked out in the future by activist shareholder advisory firms who don’t even own Tesla shares themselves, I’m not comfortable with that future,” Musk wrote in a post on X.

Tesla Cybercab is heading to China’s import expo
The event will take place from November 5–10 at Shanghai’s National Exhibition and Convention Center.
Tesla will make its return to the China International Import Expo (CIIE) this November, marking its first appearance at the event since 2022. The U.S. electric vehicle maker confirmed it will showcase its highly anticipated Cybercab, which will make its Asia-Pacific debut during the event.
The expo will take place from November 5–10 at Shanghai’s National Exhibition and Convention Center.
Tesla Cybercab in China
Tesla announced its participation in the event on its official Weibo account. As per the electric vehicle maker, it would be occupying Booth A3-03 in Hall 2.1 at the National Exhibition and Convention Center. As noted in a CNEV Post report, the Cybercab, the company’s dedicated autonomous two-seater Robotaxi, will be making its Asia-Pacific debut at the CIIE as well.
The company shared a graphic on Chinese social media which showed an image featuring several Tesla products, such as the Cybercab, Optimus, and Megapack batteries. The graphic also featured a building that read “Master Plan Part IV.”


Tesla’s momentum in China
Tesla’s return comes after skipping the event last year. Interestingly enough, Tesla attended the event from 2018 all the way to 2023. Tesla’s return to the CIIE then aligns with the company’s efforts to attract consumer interest in the world’s most competitive electric vehicle market.
The Cybercab’s presence in the event could suggest that Tesla might be interested in bringing its Robotaxi to the country. This is quite interesting as China is already home to several autonomous ride-hailing services, though Tesla’s pure vision approach, which focuses on artificial intelligence and cameras, is quite unique. So far, Tesla has only rolled out its autonomous ride-hailing services in Austin, Texas, and the Bay Area, California.
