Holden Barina 2009 Problems

Holden recalled all 2009-2010 Barinas because of a sticky valve in the Electronic Brake Control Module. If affected by the problem the braking performance was reduced and the pedal feel was spongy. That would seem to be the most likely cause of your problem. Take it to a Holden dealer and have it checked.

You certainly shouldn't need to recondition the cylinder head after such a short time. I would be checking for reasons the valves might be sticking. As the fuel injectors gave trouble shortly afterwards I would be looking to the fuel side of the engine. First, I would change fuel brands, definitely not use E10, perhaps use a higher-octane fuel, and regularly run fuel system cleaner through the car.

I would expect that the issues relating to the air-conditioner and airbags would be covered by the warranty, if you are told that it isn't then kick up a stick. Contact Holden Customer Service on 1800 033 349.

Brakes are regarded as consumable items, which are not covered by the warranty. The warranty is there to address defective items in the car. You could argue that a vibration in the brakes must mean there's a defect in them, but the time and effort required to prove that the   vibration was due to a defective part and not use or abuse would be too much to justify doing it.

I'm told that the analog AM signals being transmitted at the moment are not the best quality, stations are concentrating more on the digital signals and neglecting the analog signals that will disappear, which might explain your problems. We're also told that a reception problem should affect all stations, not just one as you suggest, and our radio expert is at a loss to explain why the interference might be worse when the brakes are applied. Perhaps take it to your local radio specialist and have them check it out for you.
