Ford Problems

I would continue to pressure the dealer, ask to see the company representative who assessed your car and took the photos, and approach Ford directly through its Customer Assistance Service.

A rotten egg smell is usually associated with a catalytic converter that has failed, but it's unusual that it has happened as such low kilometres. It will not get any better with age, and the usual way of fixing it is to replace the converter.

Dealers pay to dispose of the waste products from servicing your  car, like oils, greases, coolant, brake fluids, soiled rags, and so on, and they pass those costs on to you, the customer. Some slug you more than others. The best course of action is to go somewhere else to have your car serviced, as you have been advised.

Yours is the first report we've had, which would suggest it's not widespread. To claim it under warranty you would have to show that it was caused by a manufacturing fault, such as the windscreen being too tight in the aperture or being fitted incorrectly for example.

It's a common problem with the Territory and to my knowledge Ford hasn't come to the party with the cost of repairs, unlike the front ball joints when they did provide some relief for owners.

By the latest system I assume you mean liquid injection. You couldn't update your current system to liquid injection, you would have to remove the old system and have a new system installed. But my recommendation would be don't do it, the advantage of liquid injection over vapour is not clear. What you've got is arguably as good as you can get right now.

The cold starting system isn't working; it's probably not getting the correct fuelling at the start, so check the sensors to make sure they're working.

It's not possible to diagnose the problem from afar, you need to find a mechanic you trust and have him check for the cause. I wouldn't rush into changing the engine mounts in the hope it fixes it.
