On older Rexton models (pre-2017), the vacuum seals in the front hubs can perish, preventing 4WD engagement.

Fuel Injector Seizure
On the 2.7L diesel (Mercedes-derived), injectors can seize into the cylinder head, making them extremely difficult to replace.
Rough running, Black smoke, "Black death" (carbon buildup) around injectors
- Remove the plastic engine cover and look for tar-like deposits around the injectors
Automatic Transmission Wear
The Mercedes-sourced 7G-Tronic automatic can suffer from jerky starting and hard shifting if the transmission oil is not changed regularly (every 60,000–80,000 km).
Jerky pull-away, Hard shifting between gears, Transmission warning light, Slipping gears
