Many newer cars come fitted with a number of electronic innovations as standard. Yet while they may improve the overall driving experience, they can also increase the cost of repairs.
Warranty Direct has reported that over the past five years electrical faults on cars have increased by two thirds. Additionally, over this period, repair bills have also increased by a third. This is according to the firm's Reliability Index, which analyses cars that are more than three years old.
David Gerrans, managing director of Warranty Direct said: "As automotive technology continues to advance, cars get more and more complex. Nowhere is that more so than in the field of computer technology and other electronics.
"But, while these advances can undoubtedly improve the performance and safety of cars, they also have a knock-on effect on how often they fail and how much it costs to repair them."
To ensure that a car's electronics are kept in order for longer, make sure that it is serviced regularly. Additionally, change the battery after some time to reduce the risk of a breakdown. A selection of good quality car batteries can be bought online from ATS Euromaster, though it is worth getting a technician to fit a new one rather than doing it yourself.
Warranty Direct found that relays and alternators are the most common components found to break, however parking sensors among other new innovations have been cropping up more frequently as needing repairs.
The firm also looked into which brands are most likely to have an electrical fault and those which are not.
Subaru was found to be the most reliable, followed by Mitsubishi and then Daihatsu. Meanwhile the least reliable was Renault, then Bentley and Porsche.
Yet the cost of repairs for these brands varied considerably. For example, the cost of fixing electrics on a Subaru cost £450.67 on average. Meanwhile, for a Renault, the average cost of repairing an electrical fault is £264.33.
However, the cost of fixing an electrical fault can rise to as much as £2,804.
