Holden Vectra 2006 Problems

INCREASING the tyre inflation pressure should help, but it won't eliminate the problem. Raise the pressure to 40-45 psi and see what that does. Otherwise, you can put the car on blocks to lift the tyres off the ground.

IT IS possible the head gasket is leaking, and it can easily be checked. If it is leaking the engine should be running roughly, and the shaking when you start it cold could be a sign that it is leaking. You can check the oil for signs of coolant as further proof of a leak. Stop topping it up and driving because you risk doing further damage. Get it checked and establish the cause of the problem.

HOLDEN, I'm sure, would have told you that there are sensors built into your car that measure things such as the deceleration of the car in a crash and feeds that information to the main computer, which in turn decides if the crash is severe enough to warrant the deployment of the airbags. If the computer decides the severity of the crash exceeds the capability of the body structure and seatbelts to cope, the airbags will be triggered. That your wife walked away unscathed should tell you that the car performed well in the crash, and that the airbags weren't needed. In normal circumstances, the airbag warning light comes on when the ignition is turned on and goes off again once the system goes through its diagnostic check routine and the engine is started. If the warning light stays on, there is a problem.
