Aye, it's not the rods that are the problem on the X-Trails Turbogirl, it's the intercooler, turbo and fuel pump in that order.
Intercoolers split all the time on them, I've seen with my own eyes as low as 22k miles, although others report even worse, in the teens. Also, they like to let go on the turbo oil seals which can lead to engine runaway at worst, and new turbo at best. Last but not least the diesel pumps on them are not without failure issues either, although personally I think this is a lot to do with misfuelling and then they fail. Tolerances in them are measured down to 2 microns, and they really don't last long without the lubricity of diesel fuel. Lifespan can be measured in seconds if its a heavy enough misfuel.
Also, I've heard - but not seen, so take on it as you will - of brake failures on them, with the system going single circuit without warning.
Regards the Freelanders and the 2.5 engine, yes belts are expensive to change but they are so over-specc'd on that engine they can literally do twice the design life that Rover stated, and indeed Powertrain cleared them to 120,000, it was Rover who wnet ultra conservative on that engine. Inlet manifolds do fail on the vis motors, but thats an easy fix for a true garage, and not just a parts replacer, if you see what I mean.
Biggest Freelander common issue is that bloody transfer box. It's fragile, and it breaks. Often. Hence, as you found, the cop out is to do the economy mod on them. At least Landy owned up to the front diff being chocolate in the LR322, and issued a recall which they still honour. Sadly that never happened with the Freelander.
As for 1.8 petrol head gaskets, well, I can do one now, and do it right, in an easy gong days work, I've done that many of them for friends over the years. They are pretty much a service item if you dont use the MLS gasket, but fit and forget if you do.
With the litigation issue, well, honestly, be careful. Anything you say on a forum, be rock solid on it, as companies can take issue. I was a mod on a car site, and we had one guy come on and state about problems he had with a certain outfit. You would not believe how quickly that went legal, and how quickly he found himself in the ****. Sadly, we had to cover ourselves as well, which cost us money we could, as a group, ill afford to part with from group funds.
