@Andy and Befoandc Phone Motability, tell them the car is not fit for purpose due to manufacturers fault, at No point do you have to put up with an inferior vehicle, tell them it’s causing you distress and constant concern, you have every right to refuse the vehicle at NO cost to yourself! If it was a private lease it wouldn’t be exceptable, so it’s not exceptable to you. You pay a private company (Motability Operations) to lease the vehicle. It’s their issue and vehicle, don’t put up with it, If private sale or you hired a car from Euro Cars/Enterprise etc and an issue was raised it gets returned and replaced at no cost to yourself. Let Motability deal with it, making sure you use the words your refusing the vehicle on grounds on not fit for purpose unless sorted and a suitable hire vehicle is supplied.
@Russ unfortunately it would seem you’ve been subject to the All to common scenario where the dealership has sold the Motability vehicle to a private buyer. Make sure you let Motability know and hopefully they will fine and adjust thier back office system to reflect the bad service.
should you require you can cancel order and go elsewhere, it may be worth contacting the next closest dealership to see what stock cars they have available if time is at the essence. If your willing to wait for your new car (reordered) then fair play. I personally would walk away out of principle and order else where. I’m not sure how to stop it but reporting the ones that do to Motability is a start.
