Tesla has a knack for not performing well in some reliability and dependability surveys, and the most recently released assessment from Consumer Reports continued that trend after the electric automaker finished 27th out of 28 total brands. The report comes just days after Tesla’s Model 3 and Model S claimed two of the top three spots on Consumer Reports’ list of most satisfying cars on the market.
Only Lincoln, a brand of legacy automaker Ford, finished below Tesla. The Model X was rated Tesla’s least reliable vehicle and received 5 out of 100 possible points.
Tesla’s four all-electric vehicles boast some of the best performance and technology on the market. Ask some of the world’s biggest non-profit organizations that handle the automotive sector, and they will regularly conclude Tesla is near the bottom of the barrel. This year’s Reliability Survey from Consumer Reports showed that only the Model 3 was rated with “average” reliability, the highest mark Tesla scored in the assessment. Tesla’s other three vehicles were considered “below average.”
Tesla trifecta dominates Consumer Reports’ list of most satisfying cars on the market
Consumer Reports says that it obtains its reliability data from the Auto Surveys sent to CR members every year. The organization received responses on over 300,000 vehicles this year, detailing information from model years 2000 to 2021. CR asks about reliability and satisfaction to obtain information regarding brands. On its website, Consumer Reports shows how it obtains its rankings for reliability:
“For reliability, we ask members to note any problems with their vehicles that occurred in the previous 12 months. They are asked to identify problems that they considered serious (because of cost, failure, safety, or downtime). We ask them to include problems covered by warranty, but not the ones resulting from accident damage or due solely to recall. Respondents check off problems from a list of trouble areas, ranging from the engine and transmission to climate system, brakes, electrical system, and power accessories. They also tell us in writing (verbatim) specifically what their experiences were to help us understand precisely what problems they are having.”
Interestingly, recent reports from Tesla owners have indicated that build quality has never been better. While customer service is a noted weak point of Tesla, the company still maintains relatively positive experiences with its service. Additionally, the lack of maintenance for an electric vehicle is significantly less. However, there are plenty of owners who are also members of CR that are indicating their cars are not super reliable.
The Model 3 obtained a score of 59 for its reliability rating. The Model S, Y, and X received 20,18, and 5, respectively.

CR Director of Vehicle Testing Jake Fisher said that the Model X received incredibly low scores because of continuing issues with its falcon-wing doors. Additionally, The Model Y SUV has build quality issues, Fisher said, especially with “poorly fitting body panels, leaks, and issues with its climate control system,” he said to Reuters. Additionally, in typical CR fashion, the publication took a dig at Tesla’s Full Self-Driving feature, where Fisher said, “Full Self-Driving is not Full Self-Driving at all. It’s a convenience feature.”
Consumer Reports’ has regularly been highly critical of Tesla, so the survey results should be taken with some caution. Tesla has had a tumultuous relationship with the build quality of its vehicles, but has refined manufacturing processes in its facilities for years. CEO Elon Musk has stated that he is open to constructive criticism, and Tesla has used it to improve their vehicles’ quality.

Tesla confirms that it finally solved its 4680 battery’s dry cathode process
The suggests the company has finally resolved one of the most challenging aspects of its next-generation battery cells.
Tesla has confirmed that it is now producing both the anode and cathode of its 4680 battery cells using a dry-electrode process, marking a key breakthrough in a technology the company has been working to industrialize for years.
The update, disclosed in Tesla’s Q4 and FY 2025 update letter, suggests the company has finally resolved one of the most challenging aspects of its next-generation battery cells.
Dry cathode 4680 cells
In its Q4 and FY 2025 update letter, Tesla stated that it is now producing 4680 cells whose anode and cathode were produced during the dry electrode process. The confirmation addresses long-standing questions around whether Tesla could bring its dry cathode process into sustained production.
The disclosure was highlighted on X by Bonne Eggleston, Tesla’s Vice President of 4680 batteries, who wrote that “both electrodes use our dry process.”
Tesla first introduced the dry-electrode concept during its Battery Day presentation in 2020, pitching it as a way to simplify production, reduce factory footprint, lower costs, and improve energy density. While Tesla has been producing 4680 cells for some time, the company had previously relied on more conventional approaches for parts of the process, leading to questions about whether a full dry-electrode process could even be achieved.
4680 packs for Model Y
Tesla also revealed in its Q4 and FY 2025 Update Letter that it has begun producing battery packs for certain Model Y vehicles using its in-house 4680 cells. As per Tesla:
“We have begun to produce battery packs for certain Model Ys with our 4680 cells, unlocking an additional vector of supply to help navigate increasingly complex supply chain challenges caused by trade barriers and tariff risks.”
The timing is notable. With Tesla preparing to wind down Model S and Model X production, the Model Y and Model 3 are expected to account for an even larger share of the company’s vehicle output. Ensuring that the Model Y can be equipped with domestically produced 4680 battery packs gives Tesla greater flexibility to maintain production volumes in the United States, even as global battery supply chains face increasing complexity.

Tesla Giga Texas to feature massive Optimus V4 production line
This suggests that while the first Optimus line will be set up in the Fremont Factory, the real ramp of Optimus’ production will happen in Giga Texas.
Tesla will build Optimus 4 in Giga Texas, and its production line will be massive. This was, at least, as per recent comments by CEO Elon Musk on social media platform X.
Optimus 4 production
In response to a post on X which expressed surprise that Optimus will be produced in California, Musk stated that “Optimus 4 will be built in Texas at much higher volume.” This suggests that while the first Optimus line will be set up in the Fremont Factory, and while the line itself will be capable of producing 1 million humanoid robots per year, the real ramp of Optimus’ production will happen in Giga Texas.
This was not the first time that Elon Musk shared his plans for Optimus’ production at Gigafactory Texas. During the 2025 Annual Shareholder Meeting, he stated that Giga Texas’ Optimus line will produce 10 million units of the humanoid robot per year. He did not, however, state at the time that Giga Texas would produce Optimus V4.
“So we’re going to launch on the fastest production ramp of any product of any large complex manufactured product ever, starting with building a one-million-unit production line in Fremont. And that’s Line one. And then a ten million unit per year production line here,” Musk stated.
How big Optimus could become
During Tesla’s Q4 and FY 2025 earnings call, Musk offered additional context on the potential of Optimus. While he stated that the ramp of Optimus’ production will be deliberate at first, the humanoid robot itself will have the potential to change the world.
“Optimus really will be a general-purpose robot that can learn by observing human behavior. You can demonstrate a task or verbally describe a task or show it a task. Even show it a video, it will be able to do that task. It’s going to be a very capable robot. I think long-term Optimus will have a very significant impact on the US GDP.
“It will actually move the needle on US GDP significantly. In conclusion, there are still many who doubt our ambitions for creating amazing abundance. We are confident it can be done, and we are making the right moves technologically to ensure that it does. Tesla, Inc. has never been a company to shy away from solving the hardest problems,” Musk stated.

Rumored SpaceX-xAI merger gets apparent confirmation from Elon Musk
The comment follows reports that the rocket maker is weighing a transaction that could further consolidate Musk’s space and AI ventures.
Elon Musk appeared to confirm reports that SpaceX is exploring a potential merger with artificial intelligence startup xAI by responding positively to a post about the reported transaction on X.
Musk’s comment follows reports that the rocket maker is weighing a transaction that could further consolidate his space and AI ventures.
SpaceX xAI merger
As per a recent Reuters report, SpaceX has held discussions about merging with xAI, with the proposed structure potentially involving an exchange of xAI shares for SpaceX stock. The value, structure, and timing of any deal have not been finalized, and no agreement has been signed.
Musk appeared to acknowledge the report in a brief reply on X, responding “Yeah” to a post that described SpaceX as a future “Dyson Swarm company.” The comment references a Dyson Swarm, a sci-fi megastructure concept that consists of a massive network of satellites or structures that orbit a celestial body to harness its energy.
Reuters noted that two entities were formed in Nevada on January 21 to facilitate a potential transaction for the possible SpaceX-xAI merger. The discussions remain ongoing, and a transaction is not yet guaranteed, however.
AI and space infrastructure
A potential merger with xAI would align with Musk’s stated strategy of integrating artificial intelligence development with space-based systems. Musk has previously said that space-based infrastructure could support large-scale computing by leveraging continuous solar energy, an approach he has framed as economically scalable over time.
xAI already has operational ties to Musk’s other companies. The startup develops Grok, a large language model that holds a U.S. Department of Defense contract valued at up to $200 million. AI also plays a central role in SpaceX’s Starlink and Starshield satellite programs, which rely on automation and machine learning for network management and national security applications.
Musk has previously consolidated his businesses through share-based transactions, including Tesla’s acquisition of SolarCity in 2016 and xAI’s acquisition of X last year. Bloomberg has also claimed that Musk is considering a merger between SpaceX and Tesla in the future.
