How Customer Complaints Allow Deep Insight Into the US Market

Cars have conquered the world like a massive invasion. Over the last 100 years they have spread across the world with production figures steadily increasing over the years. In 1970 they were just under 30 million, whilst nowadays, there are 80 million cars being produced every year. In 2010, the number of cars on the planet exceeded its first billion. China is contributing nearly a quarter to the world production of cars today. In the last couple of years, the world’s stock of cars has increased by almost one car per second. Formerly comfort and status symbols were far more important than they seem to be nowadays. Instead, security and safekeeping has become extremely relevant for buyers and makers. When buying a car, have a look at the statistics. Electrical systems are not necessarily the reason for an accident, but are very often mentioned in complaints.

At the time of our research the database had 382.682 entries which make more than 5.5 million data records. The data is open to public.

For most charts we worked with the car manufacturers who have the highest number of cars on American streets. Several charts are presenting car makes: we based our calculation of “their” car complaints on absolute not relative data. Which means that when Ford has a high amount of accidents this is because they have lots of cars on American streets. Relatively they might not lead the statistic.
