Those responsible for a series of under-bonnet fires in a number of black cabs are facing legal action from hundreds of taxi drivers who are claiming for loss of earnings.
All TX4 models with a 56 registration were recalled by manufacturer London Taxis International (LTI) in September after some of the vehicles burst into flames.
All the modifications needed to make the cabs roadworthy, which includes altering the exhausts, are expected to be completed by November 12, LTI said, meaning that many drivers will have been unable to work for more than seven weeks.
Matthew Phillips of Hertfordshire-based solicitors McKeowns said: "We're currently in touch with over 300 black cab drivers affected by the recall and as a result we are in the process of mounting a large class action suit on their behalf against those responsible.
"Many more will not be aware that they are entitled to compensation for loss of earnings and we expect significantly more numbers to get in touch during the course of this crisis."
In a statement, LTI said: "Now that LTI have further insight and sufficient evidence into the root causes of the fires, LTI can now progress discussions to look at where responsibility lies for the losses that various parties (including LTI) have suffered."
