Which are South Africa's most reliable vehicles? The 2015 Ipsos Product Quality Awards winners have been announced. How does your car fare?

The overarching result from the 2015 version of this survey is that quality of vehicles continues to increase. This survey focuses intensely on the customer ownership experience. As Ipsos says, "Any motor company can participate if they supply names for interviewing, agree to the rules of syndication and participate in meetings and decisions regarding the syndicate business in a transparent and open manner." "Once again we have seen a marked improvement in quality during 2014, despite growing technological complexity in vehicles" commented the Ipsos Automotive Business Unit Director, Patrick Busschau.

"Customers in South Africa are becoming increasingly demanding where product quality and general service levels are concerned, but the local motor industry continues to keep raising the bar or at least remains on a very high level." Essentially the survey has three parts:a competitive customer experience benchmarking measurement of the sales and service satisfaction of customers within franchised dealership networks, and a benchmarking of product quality with rankings based on problems per 100 vehicles (PP100). Over 30 000 owners are contacted during a 12-month period and the purchasing/service experiences are taken into account 10-35 days after delivery. Product quality interviews occur 90 days after purchase.
