Ssangyong Rexton 2022 Problems

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.
