Tesla Inc. (NASDAQ: TSLA) has registered a local subsidiary in Vietnam, marking its entry into the Southeast Asian market as competition intensifies in neighboring China.

Tesla Motors Vietnam was registered in Ho Chi Minh City on Sept. 11 with roughly $3 million in charter capital. The entity is authorized to import, distribute and sell vehicles, though Tesla has not disclosed when sales will begin or where it plans to source cars for the market.

China Market Pressure

The expansion comes as Tesla’s dominance in China wanes. Its share of China’s battery-electric vehicle market fell to 6.6% in the second quarter from more than 15% in 2020.

Retail sales data for August highlights this divergence:

While retail demand softened, Tesla’s Shanghai factory sold 86,166 Model 3 and Model Y vehicles in August, including exports. This represents a 3.6% increase from a year earlier, following a 38% jump in July. For the first time, more than half of Shanghai production was exported during the second quarter.

Competitive Landscape in Vietnam

Vietnam presents a growth opportunity but features a dominant domestic competitor. VinFast Auto Ltd. (NASDAQ: VFS), founded by billionaire Pham Nhat Vuong’s Vingroup, stopped producing gasoline-powered vehicles in 2022 to focus entirely on EVs.

VinFast has built an extensive charging network across the country. According to an SEC filing:

• VinFast delivered 20,161 EVs in Vietnam in August.
• Preliminary domestic deliveries reached 154,073 through the first eight months of 2026.

Reuters described Vietnam as one of Southeast Asia’s fastest-growing EV markets. Chinese manufacturers, including BYD, are also expanding across the region.

Delivery Expectations

Market sentiment on Tesla’s near-term global performance remains cautious. Kalshi traders currently assign a 55% chance to Tesla topping 490,000 deliveries in the third quarter, but only a 42% chance of exceeding 495,000.

Tesla delivered a record 497,099 vehicles in the third quarter of 2025. With traders assigning less than even odds to deliveries topping 495,000 this quarter, the market leans toward a year-over-year decline despite expecting improvement from the second quarter’s 480,126 deliveries.

Tesla withheld key details about a fatal crash involving its automated driving technology, citing confidentiality claims that have drawn scrutiny from regulators and safety advocates.

The incident occurred around 3 a.m. on Oct. 31, 2025, in Mesa, Arizona. A Tesla Model 3 traveling east on Loop 202 came to a sudden and unexplained stop in an active freeway travel lane while an automated driving system was verified as engaged. A Ford F-350 struck the Tesla from behind, killing the driver.

Regulatory Scrutiny And Confidentiality

According to news reports citing a filing with the National Highway Traffic Safety Administration (NHTSA), Tesla treated the crash narrative, software version, and information regarding whether the vehicle was within its approved operating area as confidential business information.

Federal regulators have questioned the timeliness and completeness of Tesla’s crash reporting. In August 2025, NHTSA opened a formal reporting audit to determine whether incidents remained unreported and whether Tesla’s submissions contained all required and available information.

In a March 2026 filing covering eight incidents, Tesla told NHTSA that it considers marked information “wholly confidential and proprietary” and requested that it remain confidential “in perpetuity.”

Advocacy For Transparency

Amy Witherite, founder of Witherite Law Group, argued that legitimate intellectual property should be protected but trade secret claims should not justify withholding information needed to understand serious injuries or deaths.

“The public deserves more than broad claims about miles driven or overall accident statistics,” Witherite said. “Those numbers do not tell us how these systems perform in specific, dangerous situations or why a vehicle made a decision that may have contributed to a crash.”

Witherite emphasized the need for meaningful disclosure of what the vehicle detected, what the software decided, whether warnings were issued, and what the human driver was expected to do.

Information Imbalance For Victims

People involved in crashes with automated or partially automated vehicles face an information imbalance because manufacturers possess video, telematics, software records, and event data not readily available to drivers and families.

“Anyone involved in one of these crashes should understand that obtaining the complete record may require prompt legal action to preserve and secure evidence,” Witherite said. “Families should not have to fight through layers of secrecy to learn why a vehicle behaved as it did.”

Witherite Law Group is a Dallas-based personal injury firm focused on traffic safety, trucking accidents, and emerging transportation technology.
