Nissan Problems

The CX-5 is the one that gets The Tick. You should only go for diesel for heavy towing or if you drive more than 30,000km a year.

Before buying the tow vehicle you should establish what you want to tow with it. It would be a good idea to decide on the caravan you want to buy and from that determine the total weight you want the car to handle, that is the weight of the caravan when it is fully loaded ready to travel. I say that because a car rated to tow 2 tonnes means you will only be able to tow a relatively small caravan. A diesel will be more economical when towing, and if that were your priority then I would go that way. I would suggest you consider a mid-sized SUV, like a Nissan Pathfinder, Ford Territory or a Toyota Kluger.

That the dealership staff had trouble using it I think you've got good justification for some help from Nissan. We understand there are issues with the Bluetooth function, so it's probably best to consult an expert in that area.

It's far better to have more ratios, since it keeps the car's engine operating at maximum efficiency for more of the time. Top-end car companies are now going for eight speeders, which are brilliant with diesel engines. But Japanese companies are turning to constantly variable transmissions, which don't have cogs - just adjustable belts that stop at preset ratios - and these are often disruptive and the operating software is poorly tweaked.

Injector wear is a problem with all common-rail diesels, not just the Nissan. You should be able observe rough running, perhaps black smoke from the exhaust, and high fuel consumption. The chip won't be causing your ticking noise; that will be a mechanical noise. You need to determine where the noise is coming from to be able to locate the cause. One thing I would be looking at the camshaft timing chain, they wear and sometimes break on the Navara, and that's one possible source of your ticking noise.

If you don't want four-wheel drive, save the money and get the front-drive Dualis. The Kia is better but not for average family use.

The great thing about the motor trade is that there are lots of clever mechanics that are able to fix problems that the carmakers seem to be unable to do. It's always worth asking a specialist mechanic for help.

It's frustrating when a dealer misdiagnoses a problem, and then charges you for the work they've done, even though it hasn't fixed the so-called problem. In this case, from what you have told us, there really isn't a problem. You say you are able to start the car first time, every time, by simply waiting a second or so longer, it was only the dealer that claimed it was hard to start. I wouldn't trust the dealer and would take the car to someone else if you feel you need to have it checked further, in this case one who specialises in diesels.

It's the Pathfinder for me.
