Watchdog: New Fiesta crippled by Bluetooth battery drain

As more and more new cars come with smartphone integration, it’s inevitable that problems will crop up. Question is, when things go wrong – but don’t render the car undriveable – what action can you take? Dan Archer, from Peckam, south-east London, asked exactly this after software issues caused eight roadside assistance call-outs in seven months. Dan had got a great deal on his new 1.0-litre Ford Fiesta in October 2014, but within days, he’d started to experience issues with the car starting. In one instance, the Fiesta failed to fire at the airport, forcing him to take an expensive taxi ride home. After several AA visits and trips to dealers, the fault was diagnosed as a flat battery – yet the cause remained a mystery. That was until January, when Ford got in touch with Dan with a solution. It said it was an issue where the Bluetooth system would not disable when the engine was switched off. So, when stationary, the Fiesta was still searching for a Bluetooth device to connect to – causing the battery to run flat.
