Why is there a puddle of liquid under my 2024 Haval Jolion?

Most of a modern car’s systems are now sealed which means you shouldn’t find any fluids under the car, with one possible exception. And that would be some water from the air-conditioning system. One of the things air-con does is de-humidifies the air passing through it (which is why it’s so good for demisting fogged-up windows). The result of that is that the water from the atmosphere removed by the A/C has to go somewhere, and that somewhere is usually on to the ground via a vent that stops the water collecting inside the cabin. However, this vent is more likely to be located under the dashboard or perhaps under the front seats, not the rear of the vehicle.

Don’t rule out, either, a simple case of rainwater which has collected somewhere along the chassis and drains out when you pull up for the night. Did you drive through a puddle just before parking the car? That could explain the liquid, too.

Given the liquid is clear and has no smell means it probably is water, but make sure you check the levels of everything else on the vehicle and keep an eye on them to make sure you don’t have a problem. And that includes the water reservoir for the windscreen washers.

Meantime, don’t forget that a fluid leak is a warranty issue for Haval to deal with.
