Tesla recently started offering the option of upgrading the company’s older MCU1 units to an MCU2, which provides access to new features such as Sentry Mode and Tesla Theater. The process involved in this upgrade was recently shared by an owner of a 2017 Tesla Model S, who recently opted to purchase the MCU2 retrofit together with a Hardware 3 update.

Akikiki of the Tesla Motors Club forum gave details of the experience and the changes in his vehicle’s performance and features thanks to the hardware upgrades. The addition of MCU2 and Hardware 3 gave the Model S new features from the Full Self-Driving (FSD) suite’s Navigate on Autopilot feature, as well as the vehicle’s capability to visualize traffic lights, stop signs, and on-road markings.

The 2017 Model S “now has visualization that includes traffic lights, showing red, changing to green at the intersection,” Akikiki wrote. “As I drove under the light, they got larger showing green, until they disappeared as I went under them.”

The installation of the HW3 unit required for a recalibration of the Model S’ Autopilot system. The vehicle alerted Akikiki with a message on the vehicle’s Instrument Cluster (IC), stating, “CALIBRATION IN PROCESS.” The recalibration of Autopilot took ten miles total and allowed the driver to operate with Navigate on Autopilot, allowing the new visualizations to appear. The vehicle’s lane centering and steadiness while operating on Autopilot were reportedly improved with Hardware 3 installed.

Additionally, the Model S gained the ability to operate both Dashcam and Sentry Mode, both of which have been subjected to recent updates as recorded clips from both features can soon be viewed within the vehicle. Watching recorded clips in the car was previously not possible, but CEO Elon Musk and his team of engineers added the function with a recent update.

Additional features included a new WiFi card in the MCU2 that supports both 2.4 and 5GHz internet speeds, along with the vehicle’s internet browser, Tesla Theater, and Tesla Arcade.

The invoice states that the upgraded features of the Model S required Akikiki to pay a total of $2,500, all of which can be attributed to the MCU2 upgrade. The HW3 upgrade was free of charge because Akikiki purchased the FSD suite, qualifying him for a free HW3 retrofit, as per Elon Musk’s tweet back in October 2018.

Initially, Akikiki considered merely replacing the MCU1 chip, but he found that the upgrade would be just $1,000 less than the full MCU2 upgrade. “Although under warranty, the MCUs eMMC would still have the same size chip and would likely have another short life,” he said. “Out of warranty MCU1 repair would cost by today’s cost at least $1700+ including Tax. MCU2 cost is only $1,000 more than the MCU1 replacement and, in my opinion, is worth double that difference for longer life, better performance of AP and NAV plus the addition of Tesla Dashcam and Sentry.”

Older Tesla vehicles are being upgraded, so owners can experience the newest pieces of the company’s technology without having to buy a whole new car. For the Model S owner, his 2017 sedan now runs on the same hardware that Tesla’s latest vehicles operate on, giving it full range to drive and maneuver with the help of the company’s FSD suite. Not only does this increase the value of an older car immediately for owners, but it also contributes to safer driving conditions for Tesla owners and other vehicles on the road.

Tesla launches new Cybertruck trim with more features than ever for a low price

This is a considerable upgrade to the Cybertruck Rear-Wheel-Drive that Tesla offered last year. It was discontinued after just a few months, but we still have yet to see anyone share pictures of it online.

Tesla has officially launched a new trim of its all-electric Cybertruck, which has more features than previous offerings at this price point, which is an incredibly good value.

Tesla is now offering the Cybertruck All-Wheel-Drive, and starting at $59,990, it appears to be a lot of truck for the money.

Along with the sub-$60,000 starting price, Tesla gives the Cybertruck AWD a 325-mile range rating, a powered tonneau cover that houses three bed outlets. It also has Powershare capability, coil springs with adaptive damping for a refined suspension feel, Steer-by-wire and four-wheel-steering, a 6′ x 4′ composite bed, a towing capacity of 7,500 pounds, and a powered frunk.

This is a considerable upgrade to the Cybertruck Rear-Wheel-Drive that Tesla offered last year. It was discontinued after just a few months, but we still have yet to see anyone share pictures of it online.

That truck did not have a power tonneau, did not have adaptive suspension, leather seats, or nearly any of the premium features in the upper-level trims. It was not a great deal, either. It was only a $10,000 discount from the next Cybertruck trim, which meant losing a motor and a lot of premium features for not that much of a savings.

This is a much better offering from Tesla and could help the company see a bit of a resurgence from a sales perspective. Although the Cybertruck is a popular vehicle from a fan perspective, it is not a great seller, and Tesla knows it.

Tesla Cybertruck undergoes interior mod that many owners wanted

Despite it being a crowd favorite, it was simply priced out of people’s budgets, so this All-Wheel-Drive configuration should be easier to handle financially for many of those who wanted the Cybertruck but not the price tag that came with it.

It is not a far cry from what Tesla priced back in 2019, as it unveiled three trim levels back in November, nearly seven years ago: a Single Motor for $39,990, a Dual Motor for $49,990, and a Tri-Motor for $69,990.

This new AWD trim is just $10,000 off from that price tag, and accounting for inflation, Tesla is pretty close.

Deliveries are expected to begin in June 2026.

Tesla dominates JD Power EV Satisfaction ranking, grabbing top two spots

The Model 3 was the highest ranking EV considered, with a score of 804, followed by the Model Y at 797, the BMW i4 at 795, and the BMW iX at 794.

Tesla dominated JD Power’s EV Owner Satisfaction ranking for 2026, grabbing the top two spots in the survey with the Model 3 and Model Y.

The two Tesla models grabbed the first and second spots, respectively, with scores of 804 and 797 out of 1,000 possible points.

Brent Gruber, Executive Director of JD Power’s EV practice, said:

“EV market share has declined sharply following the discontinuation of the federal tax credit program in September 2025, but that dip belies steadily growing customer satisfaction among owners of new EVs. Improvements in battery technology, charging infrastructure, and overall vehicle performance have driven customer satisfaction to its highest level ever. What’s more, the vast majority of current EV owners say they will consider purchasing another EV for their next vehicle, regardless of whether they benefited from the now-expired federal tax credit.”

JD Power’s study showed three key findings: Public charging satisfaction was higher than ever, premium BEVs saw more pronounced quality improvements, and BEVs held their satisfaction ratings compared to plug-in hybrid electric vehicles (PHEVs).

Tesla Grabs Top 2 Spots

Despite what some publications might try to make you believe, Tesla is still the cream of the crop when it comes to EV ownership, and real-world owners surveyed by JD Power will prove that to you.

The Model 3 was the highest ranking EV considered, with a score of 804, followed by the Model Y at 797, the BMW i4 at 795, and the BMW iX at 794. The segment average for “Premium Battery Electric Vehicles” was 786. The Cadillac OPTIQ (762), Rivian R1S (758), Lucid Air (740), Rivian R1T (739), and Audi Q6 e-Tron (690) all finished below that threshold.

Meanwhile, a separate category for “Mass Market Battery Electric Vehicles” had the Ford Mustang Mach-E as the EV with the highest rating at 760. The segment average for this class was 727.

Tesla Supercharging Improves Public Charging Satisfaction

JD Power said the availability of public charging is “by far the most improved index factor,” and that the consistent growth of publicly available charging has helped push many consumer sentiments in a positive direction.

Most of this is due to the Tesla Supercharger Network and its expansion. However, Tesla owners are also becoming more satisfied with the infrastructure after expanding access to other EV brands, the study said.

Musk company boycott proposal at City Council meeting gets weird and ironic

The City of Davis in California held a weekly city council meeting on Tuesday, where it voted on a proposal to ban Musk-operated companies. It got weird and ironic.

A city council meeting in California that proposed banning the entry of new contracts with companies controlled by Elon Musk got weird and ironic on Tuesday night after councilmembers were forced to admit some of the entities would benefit the community.

The City of Davis in California held a weekly city council meeting on Tuesday, where it voted on a proposal called “Resolution Ending Engagement With Elon Musk-Controlled Companies and To Encourage CalPERS To Divest Stock In These Companies.”

The proposal claimed that Musk ” has used his influence and corporate platforms to promote political ideologies and activities that threaten democratic norms and institutions, including campaign finance activities that raise ethical and legal concerns.”

We reported on it on Tuesday before the meeting:

California city weighs banning Elon Musk companies like Tesla and SpaceX

However, the meeting is now published online, and it truly got strange.

While it was supported by various members of the community, you could truly tell who was completely misinformed about the influence of Musk’s companies, their current status from an economic and competitive standpoint, and how much some of Musk’s companies’ projects benefit the community.

City Council Member Admits Starlink is Helpful

One City Council member was forced to admit that Starlink, the satellite internet project established by Musk’s SpaceX, was beneficial to the community because the emergency response system utilized it for EMS, Fire, and Police communications in the event of a power outage.

After public comments were heard, councilmembers amended some of the language in the proposal to not include Starlink because of its benefits to public safety.

One community member even said, “There should be exceptions to the rule.”

Community Members Report Out of Touch Mainstream Media Narratives

Many community members very obviously read big bold headlines about how horribly Tesla is performing in terms of electric vehicles. Many pointed to “labor intimidation” tactics being used at the company’s Fremont Factory, racial discrimination lawsuits, and Musk’s political involvement as clear-cut reasons why Davis should not consider his companies for future contracts.

However, it was interesting to hear some of them speak, very obviously out of touch with reality.

Musk has encouraged unions to propose organizing at the Fremont Factory, stating that many employees would not be on board because they are already treated very well. In 2022, he invited Union leaders to come to Fremont “at their convenience.”

The UAW never took the opportunity.

Some have argued that Tesla prevented pro-union clothing at Fremont, which it did for safety reasons. An appeals court sided with Tesla, stating that the company had a right to enforce work uniforms to ensure employee safety.

Another community member said that Tesla was losing market share in the U.S. due to growing competition from legacy automakers.

“Plus, these existing auto companies have learned a lot from what Tesla has done,” she said. Interestingly, Ford, General Motors, and Stellantis have all pulled back from their EV ambitions significantly. All three took billions in financial hits.

One Resident Crosses a Line

One resident’s time at the podium included this:

He was admonished by City Council member Bapu Vaitla, who said his actions were offensive. The two sparred verbally for a few seconds before their argument ended.

City Council Vote Result

Ultimately, the City of Davis chose to pass the motion, but they also amended it to exclude Starlink because of its emergency system benefits.
