A manufacturer’s reliability is simply defined as a person or company’s ability to consistently supply an acceptable product at the required time.

A manufacturer’s reliability in the world of cars is measured by the Reliability Index (RI). The UK Reliability index takes into account all factors of a repair, the cost of the parts and the frequency of failures – The Average of all cars is 100 which means that if the figure for the car you are looking at has a higher than average index (118) it indicates that that car is less reliable than the average, if however there is a lower than average index (60) the reliability is better. Separately from this figure you can also look at the average cost of repairs for a particular make or model, a car with a good reliability index and a high average cost would imply that the frequency of failure is low, however when it does fail the bill will be a lot more than the average. Toyota, for example, has a high average cost of repair but quite a good index rating – which means that the car fails infrequently but when it does you will be in for a larger-than-average bill. Overall, however, Toyota is a very strong make of car to buy. Although Honda is ranked first in this article, Daihatsu is technically ranked number 1. According to www.autoexpress.co.uk, Daihatsu stopped selling cars in the UK in 2011 therefore we haven’t included them in this article.
