2021 Ssangyong Rexton Pricing and Specs

What you might be feeling is the vehicle shifting down a gear or two on its own. But it would be a huge jolt should the vehicle suddenly shift into low-range by itself. That’s because the low-range gearing is super-low, to enable the vehicle to produce enough torque to jump over rocks and haul itself up cliff faces and all sorts of other off-road stuff.

But whatever is going on, it’s potentially a warranty issue, so a trip back to the dealership is your next move. Having a transmissions select its own gears with no pattern to things is a great way to damage something mechanical or even cause a crash.

It sounds like you’re stressing every part of your SsangYong if you’re managing to make it overheat and the suspension sag. Are you sure the caravan is within the legally allowed towing mass for the vehicle?

You could fit stiffer rear coil springs, but before you do that, check that you have the caravan loaded properly and that it’s not placing too much weight on the tow-ball. Generally, this weight should be a maximum of 10 per cent of the van’s total mass. Any more than that and you wind up with a very dangerous rig that could be dangerous to you and other road users.

For the record, the 2022 Rexton has a towing limit of 3500kg, but the trade considers this to be a pretty big ask for the 2.2-litre engine which could be the cause of your overheating problems.

Glitches in digital displays like these are not uncommon across all makes and models. They can occur suddenly and for no good reason and while some of them can be repaired, replacement of the whole unit is a more common approach.

But don’t forget that this is a warranty job on your car, so make sure SsangYong is made aware of it, fixes it and foots the bill. A fault like this is why cars have factory warranties in the first place.
