2007 Jeep Grand Cherokee Pricing and Specs

That particular variant of the Grand Cherokee weighs an impressive 2336kg. That said, manufacturers often underquote their vehicles' kerb mass, and that could be the case here, so take it as a ball-park figure only.

If you're concerned with overloading the vehicle, the best thing to do is load it as you would and then take it to a local weighbridge to gain an accurate idea of what it weighs in-service. Many council recycling facilities (we used to call them the tip) now have weighbridges.

There are two issues here. The first is that you’re paying a lease on a vehicle that isn’t functioning right now. There’s not much that anybody can do about that and it’s not really anybody’s fault. The disaster that is current global supply chains has meant that freight out of the United States is either moving at snail’s pace or not moving at all. Many Australians are waiting for bits and pieces from North America, all of which seem to be stranded on the dock in the US. Perhaps you could talk to your finance company about some interest-rate relief, but based on past experience, I wouldn’t be holding my breath there. And since it’s not Jeep’s fault that global trade is in such a state right now, I don’t think you’d do much good there, either. Nor is this a Jeep-specific problem; many car brands are having trouble sourcing repair and service parts.

As for the vehicle being replaced, on the face of it, I doubt that you have much of a case. If Jeep refuses to or cannot repair the vehicle, then you’d have grounds for a refund or replacement, but if Jeep believes that replacing the engine will fix the problem, then consumer law allows for that to happen.

The chances of the same vehicle having two engine failures seems pretty slim, so I wouldn’t be worried about it happening again. Don’t forget that there are any number of reasons (fuel pump, sensor, electrical problem, fuse, relay and a thousand more) for an engine to stop virtually in its tracks. Again, this is not a Jeep thing; all car-makers have experienced engines that for whatever reason have simple spluttered to a stop, often at speed on the highway.

When that happens, of course, you can lose the assistance to the power-steering and the braking system which is what your wife is concerned about. But it’s probably worth explaining that even though she would have to wrench the steering wheel with lots of muscle and really stomp on the brake pedal, even if the engine stops, she would still have brakes and steering. They just won’t be power-assisted. And even if she doesn’t think she’d be able to turn the wheel if that happened, adrenalin is a very powerful force on its own in such situations. And, again, the same thing could happen in any make or model of car.

I wouldn’t be concerned about the cylinder configuration of a particular engine. What’s more important is how much power and torque that engine makes, and how towing-friendly that power delivery is. By which we mean how smooth and flexible is the delivery. What you don’t want is a peaky engine that needs to be revved before it delivers the good as that puts a strain on everything and make the vehicle tricky and unpleasant to drive.

The good news is that all the vehicles you’ve nominated have good, solid powerplants that are well suited to towing a caravan. Modern turbo-diesels – especially with an automatic transmission – are ideal for this task.

What you should go for, however, is the vehicle with the highest towing rating. In this case, that’s any of the Grand Cherokee, MU-X or older Discovery, all of which have variants that can handle a towed load of 3.5 tonnes. The Everest is almost as good with 3.1 tonne, but only almost. The problem is that the van you’ve nominated can easily weigh between 2.2 and 2.8 tonnes which, with a 3.1-tonne limit, leaves you very little headroom for water tanks and camping gear. You’d be amazed at how much a fully loaded caravan weighs, so don’t rely on the brochure, load the van and take it to a weighbridge to make sure the vehicle you have can legally tow it.
