Tesla’s L2 home charging system aces customer satisfaction ratings in J.D. Power study
It appears that it’s not just Tesla’s Supercharger Network that is well appreciated by electric vehicle owners. As per the results of the J.D. Power 2022 U.S. Electric Vehicle Experience (EVX) Home Charging Study, Tesla’s Level 2 home charging solutions have the highest customer satisfaction score in the market today.
The annual study, which was launched last year, was designed to evaluate the satisfaction of electric vehicle owners with their home charging options. Eight factors were specifically scored, from fairness of retail price, cord length, size of charger, ease of winding/storing cable, cost of charging, charging speed, ease of use, and reliability.

Three segments were also studied: Level 1 portable chargers; Level 2 portable chargers; and Level 2 permanently mounted charging solutions. Level 1 charging systems typically use 120-volt AC power and are capable of adding about 4-5 miles of range per hour. Level 2 chargers utilize 240-volt AC power and are generally capable of adding 20-30 miles of range per hour.
As noted by J.D. Power in a press release, satisfaction is currently highest among electric vehicle owners that use Level 2 portable chargers and Level 2 permanently mounted home chargers. And among the solutions that are available in the market today, Tesla’s Level 2 home charging system came out on top, scoring an impressive 797 points.
Tesla’s Level 2 charging solution outperformed every competing charger in seven out of eight factors, with the system only falling behind in retail price. Senior Director of Global Automotive at J.D. Power Brent Gruber summarized Tesla’s results in the following statement to Automotive News. “It may not be the cheapest, but it is the best performing,” he said.
If there is one thing that J.D. Power’s 2022 U.S. Electric Vehicle Experience (EVX) Home Charging Study showed, it is that customers who utilize Level 2 chargers end up with a far superior EV ownership experience compared to those who only use Level 1 chargers. The study revealed that there is a notable 188-point gap between the general satisfaction of owners using Level 1 portable chargers and those using Level 2 mounted chargers. Brent Gruber, senior director of global automotive at J.D. Power, explained this in the study’s press release.
“Home charging is an important aspect of owning an EV and taking that to the next level by utilizing a Level 2 charger is key to optimizing the ownership experience. When upgrading to Level 2 charging, some home electrical upgrades may be necessary. Making those changes will mean faster charging and result in a far more satisfactory EV ownership experience. With battery ranges increasing, it makes sense for many owners to make the upgrade if they haven’t already. All parties involved in the EV marketplace need to pay special attention to home charging since 84% of owners regularly charge at home,” Gruber said.

Elon Musk reveals date of Tesla Full Self-Driving’s next massive release
Initially planned for a January or February release, v14.3 aims to add some reasoning and logic to the decisions that Full Self-Driving makes, which could improve a lot of things, including Navigation, which is a major complaint of many owners currently.
Tesla CEO Elon Musk revealed the date of Full Self-Driving’s next massive release: v14.3.
For months, Tesla owners with Hardware 4 have been utilizing Full Self-Driving v14.2 and subsequent releases. Currently, the most up-to-date FSD version is v14.2.2.5, which has definitely brought out mixed reviews. With releases, some things get better, and other things might regress slightly.
For the most part, things are better in terms of overall behavior.
However, many owners have been looking forward to the next release, which is v14.3, about which Musk has said many great things. Back in November, Musk said that v14.3 “is where the last big piece of the puzzle lands.”
He added:
“We’re gonna add a lot of reasoning and RL (reinforcement learning). To get to serious scale, Tesla will probably need to build a giant chip fab. To have a few hundred gigawatts of AI chips per year, I don’t see that capability coming online fast enough, so we will probably have to build a fab.”

Tesla Full Self-Driving v14.2 is a considerable improvement from early versions of the suite, but we have written about the somewhat confusing updates that have come with recent versions.
Tesla Full Self-Driving v14.2.2.5 might be the most confusing release ever
They’ve been incredibly difficult to gauge in terms of progress because some things have gotten better, but there seems to be some real regression on a handful of things, especially with confidence and assertiveness.
Musk confirmed today on X that Tesla is already testing v14.3 internally right now. It will hit a wide release “in a few weeks,” so we should probably expect it by late April.
It’s in testing right now. Wide release in a few weeks.

Overall, there are high hopes that v14.3 could be a true game changer for Tesla Full Self-Driving, as many believe it could be the version that Robotaxis in Austin, Texas, some of which are driverless and unsupervised, are running.
It could also include some major additions, including “Banish,” also referred to as “Reverse Summon,” which would go find a parking spot after dropping occupants off at their destination.
What Tesla will roll out, and when exactly it arrives, all remain to be seen, but fans have been ready for a new version as v14.2.2.5 has definitely run its course. We have had a lot of readers tell us their biggest request is to fix Navigation errors, which seem to be one of the most universal complaints among daily FSD users.

Tesla Full Self-Driving gets latest bit of scrutiny from NHTSA
The analysis impacts roughly 3.2 million vehicles across the company’s entire lineup, and aims to identify how the suite’s degradation detection systems work and how effective they are when the cars encounter difficult visibility conditions.
The National Highway Traffic Safety Administration (NHTSA) has elevated its probe into Tesla’s Full Self-Driving (Supervised) suite to an Engineering Analysis.
The analysis impacts roughly 3.2 million vehicles across the company’s entire lineup, and aims to identify how the suite’s degradation detection systems work and how effective they are when the cars encounter difficult visibility conditions.
The step up into an Engineering Analysis is often required before the NHTSA will tell an automaker to issue a recall. However, this is not a guarantee that a recall will be issued.

The NTHSA wants to examine Tesla FSD’s ability to assess road conditions that have reduced visibility, as well as detect degradation to alert the driver with sufficient time to respond.
The Office of Defects Investigation (ODI) will evaluate the performance of FSD in degraded roadway conditions and the updates or modifications Tesla makes to the degradation detection system, including the timing, purpose, and capabilities of the updates.
Tesla routinely ships software updates to improve the capabilities of the FSD suite, so it will be interesting to see if various versions of FSD are tested. Interestingly, you can find many examples from real-world users of FSD handling snow-covered roads, heavy rain, and single-lane backroads.
However, there are incidents that the NHTSA has used to determine the need for this probe, at least for now. The agency said:
“Available incident data raise concerns that Tesla’s degradation detection system, both as originally deployed and later updated, fails to detect and/or warn the driver appropriately under degraded visibility conditions such as glare and airborne obscurants. In the crashes that ODI has reviewed, the system did not detect common roadway conditions that impaired camera visibility and/or provide alerts when camera performance had deteriorated until immediately before the crash occurred.”
It continues to say in its report that a review of Tesla’s responses revealed additional crashes that occurred in similar environments showed FSD “did not detect a degraded state, and/or it did not present the driver with an alert with adequate time for the driver to react. In each of these crashes, FSD also lost track of or never detected a lead vehicle in its path.”
The next steps of the NHTSA Engineering Analysis require the agency to gather further information on Tesla’s attempts to upgrade the degradation detection system. It will also analyze six recent potentially related incidents.
The investigation is listed as EA26002.
