Recently my car cruze control and speed limiter have started to fail approx 1 hour into a journey, it resets ok after restarting the engine. in the last few days the BAS has failed, followed quickly by the ESC then the anti lock brakes, at the same time the BAS fails the speedo stops working and the car stays in what ever gear it was in at the time of failure. the speedo doesnt fail every time but when it does the car wont change gear. every thing resets after the engine is switched off and on again but now quickly fails again. the car has 89000miles with full service history. The last time the BAS only failed 7 years ago I replaced the battery and it was ok after that. I had the battery tested and seemed ok but the tester said it needed charged.
