It could be a design flaw in the Fiesta, as Ford and its dealer appear to be saying, but it certainly sounds like there’s a fault in the vent system. Take it back to the dealer and ask for an explanation of how the system works, and from that you might determine whether it’s a build fault or a design flaw.
You have reported it while the warranty is in force so I would believe they are obligated to honour the warranty whether or not they report back before the warranty ends. Keep all records of the reports you have made, and any conversations you have had with the dealer/Ford, and any undertakings you have been given by either party. I they don't come good and fix your car you would then have the ammunition to mount a solid case for compensation.
One good thing is that you have the dealer on your side, or so it seems, if only Ford would come on board as well. The pinging issue is common, and the advice most owners are given is to switch to premium fuel. I would suspect that the lack of power and hesitations when cold are a separate issue, one related either to a faulty sensor that’s not telling the computer that it’s cold outside and the engine needs enrichment, or it’s an issue with the calibration itself. I have sent your concerns on to Ford and requested help to sort the issue. In the meantime, I reckon you have a good claim against Ford to refund your money or replace your car.
The dealer is trying to fix the car for your, so you can only work with them to ensure a satisfactory outcome. The dealer has an obligation not only to repair the faults in the car, but also to return it to you in the same condition it was in when you handed it over to you. Before taking it back make sure you're happy with the state of the car as it's being handed back, and don't accept it if there is anything you are unhappy with. You could also have it inspected by an independent mechanic or engineers to confirm the work has been done to an acceptable standard.
We haven't received any reports of problems with wheel bearings on these cars. The Festiva was on the market for a long time and there was nothing to suggest there was a widespread problem with it, and while the Fiesta hasn't been here for a very long time it doesn't appear to have a history of problems in that area either.
They fill the tyre with foam that supports it until you can get it replaced or repaired. They are reliable, but the foam can be a pain in the backside for the tyre people who have to clean it out in the case the tyre is repairable, and you are probably over-reacting a little.
As you state Ford recommends 91-octane fuel for your car, so you would expect it to run on regular unleaded without a problem. I assume you have tried E10 unleaded, which generally has an octane rating of at least 94. If not it might be worth trying that, but other than that go back to your dealer and point out to him that you're not happy with your car and that you want it fixed.
By the advice he gave you the dealer probably believed the engine was pinging, but switching to the higher-octane fuel did nothing to fix it. The car is still under warranty, so take it back to the dealer and ask that it be fixed again. If they can't fix it, ask them to consult Ford about the problem. Persist until it is fixed, long term pinging can cause damage to the engine.
