Thanks for the responses. After my B-Max was off the road for 2 weeks, the main Ford dealer advised that they had fitted a 'new full clutch system' and replaced some 'drive shaft bearing seals' with all repairs covered under the three month warranty. So, after collecting my car three weeks ago and covering just another circa 250 miles without any issues, guess what? The same symptoms returned this morning, only more severely than last time. When travelling slow in rush out traffic this morning and pulling away at around 1,000 to 1,500 revs, there was a real 'juddering' accompanied with a 'loss of power' for what was about 4 or 5 seconds. When power did kick in, the rev counter shot up to circa 5,000 revs without really moving me forward. So, I've just dropped off the car at the main dealer (drive of 12 miles without any issues though most of journey was on a dual carriage way at 60 mhp) and asked for the Sales Manager, who was out. I've left the car with the Service Department and advised them that I'm to email them stating that the car is not 'fit for purpose' and that it is not of 'merchantable quality' and demanded that they rebate the cost which I paid for the car.
Yes Gremlin, the car is an ex-mobility. To answer Hadrian 1, when I collected the car after the first repair, the dealership would not give my any paperwork whatsoever but simply advised me of the repair they had carried out and that the cost is to be invoice back to Ford under the warranty and would show on all Ford's records on my car. Wonder if they only did a repair or computer reset?
I'll update you on what happens next!
