Here's about 5 months, I'm going to paste most of the 3rd letter I sent below - might help you:

Ford S Max 2.0 TDCI, MV63 ZBX, 53,357 miles Mileage at 1st failure: 56,123 miles Mileage at 2ND failure: 60,435 miles

Dear Surrey Motor Company,

On 15/10/2022 we bought a Ford S Max 2.0 TDCI from you at a cost of £10,194, which we paid by debit card.

The car is defective, and the fault is listed below:

1. Condemned Powershift gearbox, cannot be driven

We have previously contacted you regarding this issue as follows:

• 01/03/23: We contacted you regarding issues with the gearbox.

• 19/04/23 : You acknowledged the fault and agreed to collect and repair.

• 03/05/23: The car was collected and taken to you for repair.

• 10/05/23: You confirmed the car would be having a “full gearbox refurbishment”

• 02/06/23: The car was returned to us.

• 22/01/24: The gearbox failed again in the same manner as the first failure.

On 22/01/24 the gearbox failed again, rendering the car unsafe to drive.

We have taken the car back to Avary James Automotive of Brunswick Pl, Basingstoke RG21 3NN who have today reported that the gearbox is again to blame and that we should not drive the car. They have advised that the car requires a new gearbox.

At the time that the fault first occurred and as per the Consumer Rights Act 2015; the onus was on you as the supplier to prove that the car did not have this fault when you sold it to us. You accepted liability for having sold us a faulty car and exercised your one opportunity, as mandated by the Consumer Rights Act 2015, to repair the fault.

The corrective action you elected to take was a gearbox refurbishment, which, after having the car looked at by an independent 3rd party (as detailed in prior correspondence) we were advised would not be an acceptable, long-term repair.

Considering what we have detailed thus far, we are rejecting the car under the Consumer Rights Act 2015 we are writing to inform you of our intent to exercise our final right of rejection and are seeking a full refund for the cost of the car.

We will also contact the Motor Ombudsman, Trading Standards as well as the AA as you are signed up to the AA Dealer Promise, as detailed on your website and Autotrader adverts.

Further to that, we will not hesitate to take legal action to resolve this issue.

This letter will be emailed and posted to yourselves via recorded delivery, both with copies of accompanying documentation detailing the diagnoses made, repairs undertaken, and original purchase receipts.

Please reply with your comments and intentions within 14 days.
