Holden Colorado: Wrong sized wheel nut

Asked by Bob Webb, Cobram, Vic.

I purchased a new RC model Holden Colorado LXR last October. About two weeks ago the police put a Defective Vehicle Notice on the car, giving me just 24 hours to rectify the problem or the rego will be suspended. The Police stated that the vehicle was unroadworthy because the wheel nuts did not fully engage on the wheel studs. The wheel studs are too short for the wheel nut to screw on more than 2/3 of the length of the wheel nut. My Colorado is standard as supplied by Holden, except it came off the production line in Thailand with steel wheels and domed wheel nuts. When this model Colorado arrives in Australia, Holden removes the steel wheels and replaces them with an alloy wheel and open wheel nuts. Holden do not replace the wheel stud with a longer one to suit the much thicker alloy wheel center which then makes it unsuitable for use with the alloy wheel. The stud appears to be about 6 mm too short. Holden is refusing to do anything about this problem, stating that my vehicle meets their specifications. A week before this, I lost the right front wheel off the vehicle driving along the highway traveling about 90 km/h towing a tandem trailer. Four of the wheel studs snapped, two bent and all wheel nuts were lost. Holden is saying the vehicle meets their specifications and that the Police are wrong, the Police are saying Holden is at fault. I am stuck with a vehicle that is "unroadworthy", having traveled only 20,000 km, is less than 1 year old and is as supplied by Holden.
