A computer glitch at Holden has left around 1500 cars unaccounted for and prompted the manufacturer to report its lowest month of production in almost seven years.
News Limited reports in some cases the computer system told dealers a car was still on the production line when it was instead in their showroom.
In other cases vehicles in transit couldn't be released because the system would not allow it.
Holden executive sales director Philip Brook told News Limited while the system had led to confusing results it would not use the glitch as an excuse for poor performance.
“The computer system is not the sole reason behind all of the decline in February, it's clearly a very tough market, but it does represent the majority of our missing numbers,” he said.
Brook said the company's February figures could change once the company went through its production and sale results in detail.
