My car has now been off the road virtually since June with a brake issue. Every time the dealer returned it to me, the problem would reappear within a day or two.
The problem started in a traffic jam, one of those stop-start situations where you move forward a few feet at a time. A warning message popped-up saying `Service Brake Assist' appeared on the consol. Within twenty miles the situation had deteriorated further to more messages, 'Service Stabilitrack' and `ABS Fault'. Finally the engine management light came on, the bong started ringing on and the braking assist switched off. I was left without power-assisted brakes until I re-booted.
After three attempts. the dealership was unable to cure the problem. The car was taken by trailer to Vauxhall at Luton mid-August and there it remains there while they investigate. I have been driving a variety of different hire-cars (provided by Vauxhall) ever since.
