I had a Peugeot 3008 auto a few years ago and after 2 years lease it suddenly lost drive at a roundabout a couple of times. went into dealer and they found nothing, kept it a month having connected its computer to main one in France.
Contacted Mob and they were great, told them I had lost confidence in car and when on holiday in Cornwall the phone signals are very restricted and if I broke down may not be able to ring RAC. They told me to look for a replacement car and gave me 1/3rd of my Ap back.
The hire car was a VW Golf and was brilliant now on my fourth VW, a Tiguan
Ring Motability and they will sort you out I’m sure , you need reliability when you go out in a car not to worry about breaking down.
good luck
