We were asked if it was necessary to change the timing chain on a D40 Navara and we correctly advised the reader that it wasn't. There is no requirement to change the chain regularly as there is on engines with timing belts, but chains do wear and sometimes they loosen or even break as we reported in our used review of the D40 a few weeks ago. Of course, when that happens you must replace the chain. It's pretty easy to hear a chain when it's loose, there's usually a loud rattling noise from the front of the engine. If you hear such a noise best get it checked out before you do some serious damage to the engine internals.
Unfortunately they are serious; it's not uncommon as you can see from Peter Dunn's report. You could consult a brake specialist and see what options they have in aftermarket pads and rotors.
I would expect that they are responsible for any damage that occurs while they have it in their care, whether it's in the workshop or the car park. As long as it happened after you handed the keys over to them and before you took the keys back. Ask to talk to the dealer principal, and if you can't get anywhere with him, seek legal advice and perhaps send them a solicitor's letter requesting they repay the cost of repairs. It's always a good idea to inspect the car with the service manager before you hand the keys over and check it again before you leave the dealership. That way you've got clear proof when something untoward happens.
The old Patrol hand grenade strikes again. There were fundamental flaws with that engine, it's one to avoid. But with yours now eight years old you're going to have trouble convincing Nissan to come to the party with the cost of repairs. They might, however, make you an offer of part payment if you press them hard enough, and that's what I would recommend you do.
It's only necessary on engines that have belts and the Navara engines have chains, so there's no requirement to replace them.
Nissan's response isn't acceptable, and you're right, the EPA would probably put your car off the road if they saw it. It isn't normal, and sounds like it's getting too much fuel when accelerating. I would have a diesel engine specialist check it; I'm sure they would be able to find the cause of the problem for you.
We haven't been alerted to the injector problem, so it's something else Navara owners should be listening for. With all the problems occurring today, you could conclude that carmakers have been cutting costs.
