Facts and figures obtained from telephonic interviews conducted in 2015 with more than 8,000 owners of 17 participating brands were used to compile the survey. The brands involved equated to 77% of the total number of passenger cars and light commercial vehicles (LCV) sold through retail dealer channels. It was made up of 71% of car sales and 90% of the LCVs retailed.
"We changed our approach and the methodology used in this annual survey in 2015 because we, as a syndicate, were finding that a high proportion of inherent vehicle design issues and shortcomings were not being reported and that the frequency of these complaints had increased over the past few years," explained Patrick Busschau, the Ipsos automotive business unit director.
"This is actually a credit to the industry because the issues that bother customers nowadays are more likely related to their individual expectations around the product experience as opposed to straight and simple defects, which are rated on a scale of the number of problems per 100 vehicles.
"The quality of vehicles being produced today is very high, with few significant problems.
"Admittedly, there are many more product recalls by the manufacturers these days, but most of these are precautionary and provide the dealer and manufacturer with the opportunity to show their commitment to customer satisfaction by handling the recall well.
"So the goalposts have changed and we have changed our measurement accordingly to allow for the design issues to be incorporated into the measurement index figure.
"However, there is a weighting applied where actual quality defects have a slightly higher impact on the customer experience and so a proportionately greater impact on the scoring."
