Ford Territory 2005 Problems

The Territory has a yellow check-engine light just on the outside of the tachometer’s face, around the 2000rpm mark. Perhaps that’s what you saw flickering on. This is probably nothing to worry about as the light immediately switched itself off, suggesting that whatever the problem was, it was a fleeting one.

This light is linked to the car’s onboard diagnostic system which monitors the entire car for faults and then logs them for future problem-shooting. If a problem occurs twice within a certain time-frame, then the check-engine light must illuminate to warn the driver to have the car checked and the problem fixed.

If the light reappears and stay lit up, then you need to act to have the problem found and fixed before it has the chance to do any permanent damage to the car’s driveline. As a side-note, a car with an illuminated check-engine light is technically unroadworthy.

It shouldn't matter how old a safety recall is, it's a safety issue, so it needs to be fixed. That's why there's no actual time limit for these repairs to be made.

Here's the official response from the Department of Infrastructure: “There are no time limits applied to vehicle recalls by the department. It is expected that if a vehicle is presented for an older recall, the manufacturer will repair it as per the original recall notice”.

The potential spanner in the works there would be if the manufacturer is no longer represented in Australia or, if the parts required were no longer being made or otherwise available. In any case, this would definitely be worth chasing up with Ford as the recall was for potentially faulty brake lines which could cause a catastrophic failure with horrendous results.

Relatively modern, computerised cars like the Territory absolutely loathe low battery voltage. Without enough electricity to power all the fuel-injection and electronic ignition systems (not to mention the electric fuel pump and the on-board computers) the car will never run properly and is a good bet to enter limp-home mode as you've described. Other symptoms include the dazzling array of warning lights on the dashboard as the various on-board computer systems are left high and dry by a lack of voltage.

You're possibly on the right track with a replacement alternator as the 12.6 volts it's outputting is nowhere near enough to power the Territory successfully. Closer to 14 volts (at least about 13.7) checked at the battery terminal with the engine running and all lights and accessories switched off is where you should be.

Unfortunately, you've already replaced a whole bunch of parts that were probably okay. This approach of random replacement can ultimately cost you a lot of money you didn't need to spend, and a much better way is to have the car scanned to see if there's any electronic fault codes to give you a clue on what's wrong. But even if the alternator is not the sole cause of your problems, at 12.6 volts it is, indeed, worn out and should be replaced or reconditioned.

It sounds as though the engine’s idle-speed is set a little too low, and that’s making the engine feel lumpy (because it’s almost stalling). Having the transmission in Drive is adding a little load to the equation, slowing the engine even further. There are many things that can cause this, including a stepper-motor that is faulty and not controlling the idle properly.

The best advice is to have the car scanned for a hardware or sensor fault and proceed from there. But first, try this: With the engine idling and in Drive (and the vibration present) turn off the air-conditioning. If the vibration goes away, it could be that the electronics that detect the extra drag of the air-conditioner and automatically bump up the idle, aren’t working properly.

The transmission in this era of Ford Territories was notorious for suffering a failed transmission oil cooler. If that happened, the coolant would often mix with the transmission’s fluid, causing massive damage to both the electronics and the mechanical components of the transmission. In severe cases, the vehicle could lose drive altogether. A replacement transmission is the usual fix, so it’s an expensive failure.

But the first check to make is of another part of the Territory that is also known for giving trouble. In this case, though, the end result is nothing like as dramatic as it’s caused by damaged or poorly adjusted (loose) selector linkages. A quick tighten or adjustment will have the transmission operating properly again, but you need to ascertain what’s causing your problem in the first place. Don’t forget to check that there’s actually sufficient fluid inside the transmission, too, as low fluid can cause a loss of drive. Most workshops will be able to diagnose either problem pretty quickly.

You could visually check the transfer case and CV joints, but I doubt you’ll see anything that might tell there’s a problem with them. It could also be a diff. Get it to a specialist mechanic and have them check it for you.

The recall was to inspect the front-end on the Territory when it became obvious there was a widespread problem with the front lower balljoints wearing out prematurely. It related to the early models, which included yours. It was an inspection and some balljoints that were worn were replaced, but it didn't fix the problem. The balljoints still wear and as a rule require replacement every 75,000 km or so for the rest of the car's life. There was change to the design of the Territory front-end in in 2010 and that fixed the problem. I doubt you'll have any joy getting Ford to replace the joints for you free of charge; your car is now 11 years old and well out of warranty.

Unfortunately I don't think there is much you can do about it, the car is 10 years old and well beyond the warranty. It's even stretching the limit where you might expect goodwill. You bought an old car without inspecting it, took the salesman's word, and bought a model with known issues.
