Buying Tips for the 2023 Jeep Renegade

✓Check the operation of the Uconnect touchscreen, which is notorious for freezing, lagging, or randomly rebooting.
✓Test the manual gearbox for a smooth shift; the synchros can wear prematurely, especially on city-driven 1.6-litre diesels.
✓Listen for wind noise around the upright A-pillars and boxy wing mirrors at motorway speeds.
✓Inspect the My Sky removable roof panels (if fitted) for leaks and ensure the locking mechanisms are not seized.
✓Check for illuminated engine management lights; oxygen sensors and coil pack failures are common on the petrol engines.
✓Verify the operation of the electronic parking brake, which can stick or fail to release entirely.
