Mazda SUV Range

This is not as simple as perhaps it should be. Different carmakers use different methods to calculate cargo space, and Mazda uses the VDA method which uses 200mm X 100mm X 50mm blocks to determine the volume. In this case, the CX-5 has a volume of 438 litres with the rear seats up and 1340 litres with the seat folded down.

However, you need to know the dimensions in centimetres, so here’s how it pans out: The CX-5 has a luggage space length of 89.7cm with the rear seat in place, 171.5cm with the seat folded, a luggage space height of 82.7cm and a width of 105cm at its narrowest point.

Perhaps that helps, but the best way by far (if possible) is to visit a Mazda showroom with the wheelchair in question and physically see if it fits.

The problem of the sump filling with diesel was not unknown on early CX-5 diesels. A leaking injector is possible, but the main cause of this was believed to be the car’s DPF regeneration process dumping large amounts of fuel into the engine, some of which finds its way past the piston rings and into the sump. Either way, a new engine is a large expense.

There’s every chance that Mazda won’t offer any help given the age of the vehicle, nor is this type of engine damage usually a cause for an insurance claim. It would definitely be worth contacting Mazda Australia’s customer service division, but don’t hold your breath.

This sounds like a potentially very dangerous fault. Any car that wanders across the road or doesn’t go where the driver points it is an accident waiting to happen. A serious one, at that. At this point, the first piece of advice is to not drive the vehicle any farther and have it towed to a workshop for it to be inspected.

There’s one other possibility here. And that is that what you’re feeling is the car’s lane-keeping assistance program. This can often feel as though the steering it trying to plot its own course (which it is, in a way) in order to keep you centred in your lane. It only works up to a point, beyond which driver input will overcome it. I wonder if that’s what you mean by 'unsticking' the steering.

However, as far as I can tell, this model Mazda didn’t some with lane-keeping assistance (it has lane-departure warning only) so I think you’re back to square one and a tow-truck. Either way, this should be a warranty issue if there’s anything seriously wrong, so don’t be afraid to try a different dealership.
