The study, published by the Trading Standards Institute, claimed 76 per cent of garages did not service cars correctly, with 36 per cent of these vehicles left with major faults, including one with imminent brake failure.
Most of the garages in the survey were members of the Retail Motor Industry Federation and the Scottish Motor Trade Association, said the TSI, prompting it to call for government regulation if the situation did not change.
This could mean mandatory licensing, so that those garages that continually do a bad job could be struck off their registration would be ended and they would cease doing business, a TSI spokesman said.
