Ford Fiesta 2010 Problems

I understand the 2010 Fiesta came with a space saver spare tyre. I'd be trying a wreckers to find a replacement, but make sure it actually fits your car. Plenty of space savers will look the same, but feature a different PCD (nut spacing), offset and overall diameter. 

Ford deleted the spare wheel in the WT Fiesta, saying buyers preferred to have more features than a spare wheel. Instead the car came with a 'Mobility' kit, which could be used to inflate a punctured tyre to get you to a place where the puncture could be repaired.

Your best course of action is to take it back and ask that it be fixed at their cost. It's all down to negotiation I'm afraid, but if they are reputable people they should come to the party.

Haven’t you suffered enough? You’ve endured five years of misery, just get out of the car and get into something more reliable. You could attempt to negotiate extended warranty coverage with Ford, but I doubt they will be interested beyond the extended warranty they have already given you.

It suggests there could be a loss of oil pressure, so don't drive it, instead take it to a mechanic to have it checked.

You’re right; a cylinder head gasket shouldn’t just ‘let go’. Ask your dealer to request Ford to cover at least part of the cost of repairing your car. Even though the warranty has expired they still have an obligation under consumer laws to support the vehicle.

I understand your frustration at a dealer not being able to fix a problem with one of its cars, but it would appear that Ford and the dealer have worked out a way of dealing with the problem, even if it does involve an outside third party. Using specialists other than their own staff members is not unusual, so I wouldn't be too concerned about that. That the dealer is arranging for the work to happen puts the responsibility onto him to get it fixed to your satisfaction. You could go to fair Trading, but I would persist with the dealer and hope that it the auto electrician does fix it.
