自動車信頼性評価 （VDS）Key Findings
Key study findings~2015
- Among owners who experienced a Bluetooth pairing/connectivity problem, 55 percent say that their vehicle would not recognize their phone, and 31 percent say the phone would not automatically connect when entering their vehicle.
- The number of engine/transmission problems remains high. Nearly 30 percent of the reported powertrain problems are a result of automatic transmission hesitation and rough shifting.
- Six of the top 10 problems are design-related as opposed to defects or malfunctions.
- By vehicle category, the most frequently reported problems are related to exterior, followed by engine/transmission and audio/communication/entertainm
- Overall vehicle dependability industry-wide averages 147 PP100, or approximately 1.5 problems per vehicle.
key study findings~2016
33,560 original owners of 2013 model-year vehicles
- The overall industry average is 152 PP100 this year, compared with 147 PP100 last year.
- Among owners who experienced a Bluetooth pairing/connectivity problem, 53% said the vehicle didn’t find/recognize their mobile phone/device.
- Among owners who indicate having experienced a voice recognition problem, 67% say the problem was related to the system not recognizing/misinterpreting verbal commands.
- The number of engine/transmission problems decreases to 24 PP100 in 2016 from 26 PP100 in 2015.
- Seven of the top 10 problems are design-related. Design-related problems account for 39% of problems reported in the study (60 PP100), a 2-percentage-point increase from 2015.
Key study findings~2017
35,186 original owners of 2014 model-year vehicles
- Continuing increases in technology-related problems have contributed to dependability worsening in the industry for a second consecutive year. The industry average of 156 PP100 is a 4 PP100 increase from 2016.
- The Audio/Communication/Entertainm
ent/Navigation (ACEN) category continues to be the most problematic area, accounting for 22% of all problems reported—up from 20% last year.
- For a third consecutive year, the problems most reported by owners are Bluetooth pairing/connectivity and built-in voice recognition misinterpreting commands.
- New to the top 10 list of problems reported in 2017 is battery failure. In fact, 44% more owners report a battery failure this year than in 2016. Batteries are the most frequently replaced component not related to normal wear and tear in 3-year-old vehicles at 6.1%—up 1.3 percentage points from 2016.
Key study findings~2018
36,896 original owners of 2015 model-year vehicles
- In-vehicle technology continues to be most problematic: Audio/Communicati
ons/ Entertainment/Navigation (ACEN) remains a troublesome category for vehicle owners, receiving the highest frequency of complaints. The two most common problems relate to built-in voice recognition (9.3 PP100) and built-in Bluetooth connectivity (7.7 PP100).
- Mass Market brands continue to close the gap with Luxury brands: The Mass Market average (143 PP100) is now just 7 PP100 behind the Luxury average (136 PP100). This is a result of many high-volume vehicles rewarding their owners with excellent long-term dependability.
