The Vehicle Industry Association is pulling its support for the Clean Car Discount Scheme.
The Government has been playing down for months problems with the data, especially for used cars, that determines if vehicle buyers get a rebate, pay nothing or pay a fee.
However, the Vehicle Industry Association (VIA) said the problems persisted and it could not back the scheme any longer.
Its thousands of car dealer members had been complicit in the Government "stealing money from consumers" due to incorrect data, chief executive David Vinsen said.
