2013 Mazda CX-5 Pricing and Specs

Clearly water is getting into the car and causing your problem, so the trick is to find where it’s getting in. For start, have a feel around the seats and carpets to see if you can feel a damp patch. That will help narrow down the entry point. So will locking the car up on a warm day and noting which windows fog up.

Once you’ve done that you can start looking closely at all the rubber seals around the windows and doors as these are a likely culprit. Believe it or not, even a simple leaf or twig stuck to the rubber sealing surface can allow rainwater in, and any little nick or tear in the rubber can do likewise. It might sound basic, but are all the windows closing properly? Does the car have a sunroof, as these are notorious for letting water in even when they’re closed?

If you can find a volunteer, have them sit in the car while you take a garden hose to it. If the leak is a bad one, they might be able to spot it. Other times, though, the car needs to be moving for the water to be forced or even sucked in.

You should also check the level of coolant in your radiator or overflow bottle. If the heater matrix inside the car is leaking coolant, you’ll get the same symptoms over time. The clue there is that if the heater is leaking, the level in the radiator will fall.

Putting ride-handling up against comfort will mean a compromise on one side, as sporty-feeling SUVs tend to be a bit harsh in the ride with tyre noise as well. The Mazda CX-5 is the benchmark in the class, but the Honda HR-V could be more comfortable and flexible in the cabin.

The CX-5 is rated to tow 1800 kg (braked) and as long as you stay within that limit you should be fine. There shouldn’t be any need to fit an additional transmission oil cooler, and any increase in tyre wear should be minimal.
