J.D. Power: Tesla Supercharger network is more reliable than rivals
Tesla’s Supercharger network is substantially more reliable than its competitors in the market today. This was according to J.D. Power’s recent E-Vision Intelligence Report.
During the first quarter of 2023, around 21.6% of EV drivers who visited non-Tesla public charging stalls found that they were unable to charge their electric vehicles. In comparison, only 3.9% of Tesla drivers using the Tesla Supercharger network reported similar issues.
“When it comes to reliability, no other provider is even close to Tesla,” J.D. Power’s report noted.
The J.D. Power study noted Tesla vehicle owners reported the highest public charging satisfaction. On a 1,000-point scale, Tesla scored 734, while the average for all other manufacturers was 558 points. Tesla’s 19,500-strong Supercharger network is the largest EV charging network in the US as well, as networks using the Combined Charging System have about 11,500 fast chargers.
“Tesla simply has the largest and most reliable fast-charging network,” the J.D. Power report said.
The Tesla Supercharger network’s high scores in J.D. Power’s E-Vision Intelligence Report come as no surprise, as the electric vehicle maker has extensive experience with rapid charging systems. This is perhaps one of the key reasons why Tesla’s North American Charging Standard (NACS) is steadily gaining traction in the United States today.
Tesla’s NACS is gaining so much momentum that it is likely on track to become an industry standard in North America, as noted in an Automotive News report. Ford, General Motors, Rivian, and Volvo have reached agreements to adopt Tesla’s North American Charging Standard on their EVs over the next several years. Stellantis and Hyundai are considering similar deals.
SAE International also announced that it would be supporting the standardization of Tesla’s NACS by developing manufacturing, performance, and reliability standards for the system. The initiative is expected to be implemented on an expedited timeline.
J.D. Power, for its part, noted that the Supercharger network benefits from being more vertically integrated than its competitors. Elizabeth Krear, J.D. Power’s vice president for EV practice, described this advantage. “This enables Tesla to control and test the compatibility between the vehicle hardware and software and the Supercharger hardware and software,” she said.
It is no secret that the Supercharger network is indeed one of the best parts of the Tesla ownership experience. If this experience could be replicated through the adoption of NACS, then non-Tesla carmakers could provide a better charging experience for their customers.
“Lack of public charging infrastructure has been the top consumer barrier to EV adoption for the past 12 months, followed by related issues involving range anxiety, time required to charge, and inability to charge at home or work. If the Tesla user experience can be replicated for the non-Tesla EV users, then adoption of NACS by non-Tesla manufacturers could improve the overall charging experience and reliability,” Krear noted.

Tesla revealed a major new Cybercab detail in a guide it released for First Responders, showing new territory in its beliefs and intentions for the ride-hailing-focused vehicle that entered production in April.
The First Responders Guide is released to give fire departments, paramedics, and other emergency personnel the proper guidance on what to do in the event of an accident, entrapment, or other situation that would require immediate attention.
On one of the pages of the First Responders Guide, Tesla revealed a stark detail about the Cybercab, which could help personnel enter the vehicle more easily in case of an emergency.
Tesla Cybercab has one important piece that AI4 cars might need for FSD
It shows Tesla has no intention of releasing any Cybercab units that were initially proposed for ride-hailing services for the general public with any manual controls, meaning a steering wheel or pedals:
“A Cybercab equipped with steering wheel, brake pedal, and an acceleration pedal is typically an engineering or test vehicle, and operates at SAE Level 2 autonomy. Cybercab is not typically equipped with a steering wheel or acceleration and brake pedals.”

This is a major development for those who continue to believe Tesla planned to release the Cybercab with any sort of manual controls so that passengers could take over if needed. However, when Tesla started manufacturing production versions of the Cybercab in Giga Texas earlier this year, they were spotted without a steering wheel or pedals.
It essentially confirms the company has no intentions of bringing manual controls to the car’s production versions. Some have argued that the likelihood of Tesla having something
There still are some Cybercab units out there with a steering wheel and pedals, and as Tesla said, these cars are engineering or test vehicles, which have Safety Monitors on board to help the car out of a precarious situation or emergency.
Tesla released the Full Self-Driving v14 ‘Lite’ suite to owners of Hardware 3 or AI3 vehicles today, adding several new features to the vehicles that were once believed to be capable of unsupervised self-driving.
Now, Tesla has released this modified suite to older Tesla vehicles, adding plenty of new features and capabilities.
Here are the full release notes for the suite:
- Distilled the intelligence from HW4 V14 into HW3. This allows HW3 to directly learn how to handle scenarios using HW4 V14 as a guide. This process unlocks the improvements that have been made to HW4 including Reinforcement Learning (RL) and offline models for HW3.
- Improved both proactive and reactive responsiveness across a wide variety of categories including navigation handling, merges and forks, pedestrian interactions, traffic lights, and vehicle cut-in scenarios.
- Improved general comfort in nominal scenarios through fewer false slowdowns, smoother steering and more consistent lane centering.
- Introduced parking, unparking, and reversing capabilities.
- Added Arrival Options for you to select where FSD should park: in a Parking Lot, on the Street, in a Driveway, or at the Curbside.
- Speed Profiles are now available at all times, to further customize driving style preference.
These improvements, according to Tesla’s Head of AI, Ashok Elluswamy, help distill the driving behavior from AI4’s v14 series into both the camera and compute configurations of AI3.
Tesla Full Self-Driving v14 ‘Lite’ for older cars finally gets released
He added:
“It includes destination options and speed profiles on city roads, but more importantly significantly improved safety. We hope you’ll enjoy it, once the build ships wide.”
FSD v14 Lite is now rolling out to AI3 early-access customers. Based on the feedback, will rollout to more customers over the next few weeks.

Tesla will continue to roll out the v14 Lite suite more widely in the coming weeks, the company said.
Tesla has finally released its Full Self-Driving v14 ‘Lite’ suite for older cars that equip the Hardware 3 or AI 3 chip, which have not been able to handle the newest versions of the company’s driver assistance software.
Tesla officially started releasing the v14 Lite suite to owners in the Early Access Program last night. The company’s Head of AI, Ashok Elluswamy, said that the rollout will continue over the next few weeks. The build distills the driving behavior from AI4’s v14 series into both the camera and compute configurations of an AI3 car.

It also includes a variety of new features that were available to AI4 cars running v14, including:
- Start Self-Driving from Park
- Arrival and Parking Options
- Speed Profiles
The release is highly anticipated because those owners with AI3 vehicles were early adopters into the FSD platform and were promised that their cars would be capable of achieving Full Self-Driving.
However, Tesla CEO Elon Musk admitted during the company’s recent Q1 Earnings Call that these vehicles would not be capable of achieving unsupervised Full Self-Driving, which is what Tesla had originally said.
Owners were not pleased with this answer, or the idea that their commitment to buying the suite outright for thousands of dollars would not yield the ability to drive without operating the car. Tesla gave some solutions for this, including a discount on a new car, or an upgrade to an AI4 or AI5 self-driving computer and new, upgraded cameras.
Tesla owners do not seem pleased with these options, as they require giving the company more money.
Nevertheless, it is important to note that Tesla came through for owners here by releasing v14 Lite before the end of Q2, something it had promised owners during the previous Earnings Call. Tesla has had trouble keeping up with timelines, but this is a big achievement for the team.
