Advanced Vehicle Technologies in Japan Continue to be Problematic, J.D. Power Finds
Lexus Ranks Highest among Luxury Brands; Subaru Ranks Highest among Mass Market Brands
TOKYO: 15 Nov. 2023 — Advanced technologies in new vehicles in Japan have become more
problematic, according to the J.D. Power 2023 Japan Tech Experience Index (TXI) Study,SM released
today. Specifically, 14 of the 23 advanced technologies are the same technologies as in 2022, but theaverage number of PP100 for these 14 technologies in 2023 is 13.3 PP100, which is a worse scorethan 11.9 PP100 in 2022.
“There has been an increase since 2022 in new-vehicle advanced technologies installation and anincrease in problems cited,” said Yuji Sasaki, director of the research division at J.D. Power. “If thetechnologies with unsatisfactory performance and operability continue to be installed on new vehicles
it will lead to a decrease in initial quality satisfaction. Moving forward, it is necessary for
manufacturers of these technologies to resolve the existing issues before installation and to provide
drivers with a thorough explanation when they purchase their new vehicle to negate the currentdissatisfaction.”
The study specifically focuses on the installation of advanced technologies on new vehicles andusage and problems experienced with these features, as well as user intentions to recommend andrepurchase, based on 34 features that include 23 advanced technologies and 11 emerging
technologies. The survey calculates the market depth index, which shows the state of penetration
based on the equipment rate and usage experience of 23 advanced technologies, as well as theexecution index, which shows the state of technology evaluation based on ratings and problemexperience. The innovation index, a comprehensive index of penetration and user evaluation, iscalculated on a 1,000-point scale.
Following are key findings of the 2023 study:•Installation of new advanced technologies increases: The study examines 23 advanced
technologies. Among these, 20 are comparable to 2022 and 14 have been more frequently
installed on new vehicles this year than last year. This indicates an increase in the types andnumber of such technologies year over year. The top three most frequently installed technologies
on 2023 vehicles are drive recorders (70%); reverse automatic emergency braking systems (41%);
and active driving assistance systems (36%). The top three technologies most frequently installed
on 2023 vehicles compared with 2022 vehicles are rear seat reminder systems (8% in 2023 vs.4%in 2022); active lane change assist systems (4% in 2023 vs.1%); and front cross traffic warningsystems (4% in 2023 vs. 1%).

•Technologies with increases in problems result in lower future installation intentions: The mostfrequently cited problems with advanced technologies include interior gesture controls (55.9PP100); facial recognition systems (36.5 PP100); and direct driver monitoring systems (23.4PP100). Future installation intentions are also lower for these technologies, with only 6% of users
of interior gesture controls and 18% of users of facial recognition systems and direct monitoring
systems say they “definitely will” install these technologies on their next new vehicle. Thissuggests that it is necessary to improve these technologies or reconsider which technologies
should be installed on new vehicles.

•Lexus ranks highest overall for Tech Innovation for the first time: In the innovation rankings,
which are calculated based on installations and user evaluations of the advanced technologies,
Lexus ranks highest overall for Tech Innovation for the first time. In the past year, more advanced
technologies have been installed on Lexus models. Among the 14 brands included in the rankings(for both luxury and mass market brands), Lexus receives the highest scores for both market depth
index and execution index.

•Vehicle users more likely to use smartphone mirroring than built-in navigation systems: In theJ.D. Power 2023 Japan Automotive Performance, Execution and Layout (APEAL) Study,SM which
was fielded in conjunction with this study, users were asked which system they prefer to use as anavigation feature. More than three-fourths (79%) cite the built-in navigation system. However, thispercentage has decreased from 81% in 2022 and 82% in 2021. Use of Android Auto/ Apple CarPlay
apps is increasingly the preferred system, with 7% of users citing this in 2023, compared with 5% in2022 and 3% in 2021.This trend is more prevalent among users who are 39 years old or younger.
Users in this group have less frequently used built-in navigation systems, 68% in 2023 vs. 75% in
2021, and have more frequently used Android Auto/Apple CarPlay apps, 13% in 2023 vs. 6% in
2021. According to the J.D. Power U.S. Automotive Performance, Execution and Layout (APEAL)
StudySM published in August 2023, 43% of users use built-in navigation systems and 44% use
Android Auto/Apple CarPlay apps, indicating a larger shift to the smartphone mirroring than inJapan. It is important for manufacturers in Japan to note if users in Japan also shift to using
smartphone mirroring.

Highest-Ranked Brands
Lexus (614) ranks highest overall for innovation. Subaru (587) ranks highest among mass marketbrands.
The 2023 Japan Tech Experience Index (TXI) Study is based on responses from 21,647 users of newvehicles in the first two to 13 months of ownership. The study was fielded in May-June 2023.
