Increasingly complex electronics are making cars more prone to expensive breakdowns say Warranty Direct.
Electrical faults have increased by an astonishing two thirds over the last five years and are now the most common issue, with almost a quarter of covered vehicles (23%) needing a repair every year.
It’s a double headache as the average cost of repairing failures caused by these electrical gremlins has also increased by nearly a third over the same period, to £300. Relays and alternators are the most likely components to break but newer electronic innovations like parking sensors are typically amongst the many faults reported.
Warranty Direct managing director, David Gerrans, said: “As automotive technology continues to advance, cars get more and more complex 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.”
