Nissan Navara Problems

No, an automatic transmission — not to be confused with an automated manual shift gearbox that does use a regular clutch like a manual — doesn’t use a clutch plate. It uses a torque converter, which actually helps when towing because it multiplies the torque down low and that makes it easier to get away from the mark. The thing with the auto, particularly if used for towing, is to have an adequate cooler to make sure it doesn’t overheat and cook the fluid and clutch packs it uses.

We phoned around and the price you were quoted was very close to the prices we were quoted, it was actually lower than one. Few of us look beyond the purchase price when we buy a new car, but it’s a good idea to check the ongoing costs we will face after we’ve bought it. You experience is a good example; by buying the Navara you face higher servicing costs.

Like you, I reckon the Nissan diffs aren't up to the job; we have had a number of readers contact us after having problems. The diff failure is one thing, but it's sometimes compounded by the dealer simply seeking to replace the failed diff with another factory one, instead of having it rebuilt as your dealer did. Replacement diffs obviously take time to procure, which leaves the owner out of wheels while waiting for it to arrive and be fitted.

OPINIONS vary on how often you should run it on petrol, but once a week is a good average. You can use regular unleaded or E10.

THE 2.5-litre Navara diesel should handle your towing needs comfortably. The Navara is a great dual-cab ute for the family. It's comfortable, roomy, has a good towing capability and is economical.

As the repairs were not carried out by a Nissan dealer you need to submit a detailed report on the failure written by the people who did the work. It should be accompanied by a letter requesting that Nissan reimburse you for the cost of repairs. Unfortunately you are in a situation where it's your word against theirs, so you need to have good backup documentation in support of your case. If you don't get any satisfaction there you could resort to legal action.

RETURN it to the dealer and park it there until it's fixed. It appears your car is unroadworthy. Demand the dealer fix it, and have them give you a replacement vehicle in the meantime.

I would expect a carmaker to have a new diff on hand to replace a broken one in a matter of a day or two at most; to have to wait more than a month is unacceptable and I can understand your frustration. I suspect that Nissan has cut back on parts inventory because of the global financial meltdown, but that doesn't in any way excuse them for what is clearly the shabby treatment you received.

I would be tempted in your case because you do a lot of kays, and because of the issues with the D40 diffs. I probably would take it up.
