Re: Should I expect trouble with an 06 Focus ZX4 ST?
I'd check with the dealer to see if they have the previous maintenance records on file. If they do, that's GREAT, as they know what was done to the car and when, such as oil changes, transmission fluid changes (still a bit early with 70K kms), etc.
Otherwise, I haven't heard of any major issues, but you can always phone another dealer, give them your VIN and they can look up any technical service bulletins or even recalls that were done, or not done (if any exist). I mention to phone another dealer, just so when you go to your dealer for service, you can TELL them to do what hasn't been done and will be covered (Ford will fix at no charge for recalls & TSB's). I find it better to do some homework on the matter, and you were right in coming to this site. Not all dealers treat their clients the same. This is why it's best to phone another dealer (one that doesn't see your vehicle regularly) to see what needs to be done to it - if anything.
If the second dealer can't find any problems to fix/update then ask the same question at your regular dealer. Chances are if it's been inspected by the dealer, all TSBs and software updates should be done; again, if there are any.
Be sure to stick with the maintenance schedule in your owners manual to get the most life out of your components. If you change to synthetic oil, you can easily go 10,000kms on an oil change, if not longer in most cases. I can drive up to 40,000kms a year on my Amsoil oil I use. I rarely drive more than 25K kms a year, but once I factor in some idling time in traffic, towing, etc, it adds up close to 40,000kms of use and abuse. That's just food for thought should you be interested.
