I am wondering if anyone had any other ideas as to what we can do....will try and be short
Background
Car - just under 3 years old - 6000 (genuine Mileage on the clock) still under 3 year warranty.
Fault
MPV with electric doors - car unlocked itself and fully opened the doors on two recent occassions - last week locked me and two small children INSIDE the car and did not start - unable to be jumped or battery charged - booked to garage for warranty repair - arranged towing at cost of £65 (as unable to be started).
Garage Response
Cannot find a fault on diagnostic.
Supercharged the battery and car will start
Original diagnosis - WE must have caused the fault by leaving an interior light on - refuse to believe door opening issue occurred. Accepted that as there was no interior light on when recharged this could not be the fault.
Second diagnosis - this is a spare/irregular use car - we are responsible for the fault (which they cannot diagnose) as we do not drive the car correctly - it needs to be regularly driven to function and if we do not dso this we are responsible for any failures (not told this on purchase from same dealer - who advised based on our requirement about which we were honest and took partX on 3 year old car with less mileage)
Garage insist on charging labour for the 3 hours they spent NOT diagnosing the fault and are holding the car to ransom unless we pay - Manufacturer customer support (Inappropriate name believe me) says it must support the dealer analysis that we drive the vehicle inappropriately and are therefore liable.
I understand that they have a legal right to hold the car to ransom - and that small claims is the only legal recourse - Please Please - any other ideas? The dealer although a chain does not seem to be a member of a trade association. Appreciate any thoughts
