1. Engine and its malfunctions

⚠ Oil leaks (2.0L, 2.5L V6) – weak cylinder head gaskets, crankshaft seals.

⚠ Increased oil consumption (2.5L V6 KL-DE) – wear of oil scraper rings.

⚠ Knocking hydraulic lifters (2.0L, 1.8L) – especially in winter, flushing or replacement is required.

⚠ Timing belt wear (diesel 2.0 RF-T) – if broken, it can damage valves.

✅ Advice: change the oil regularly and check the condition of the gaskets.

2. Transmission (manual and automatic transmission)

⚠ Automatic transmission problems (GF/GW) – overheating, slipping, hard shifting.

⚠ Wear of 2nd gear synchronizers (5-speed manual transmission) – complex repair.

⚠ Gearbox oil seal leaks – especially in older cars.

✅ Advice: change the gearbox oil every 40-60 thousand km.

3. Suspension and steering

⚠ Rapid wear of the front levers and stabilizer bushings.

⚠ Knocking steering racks – especially after 150,000 km.

⚠ Shock absorbers lose their effectiveness after 100-120 thousand km.

✅ Advice: monitor the condition of the struts and change the stabilizer bushings at the first symptoms.

4. Electrics and electronics

⚠ Failure of the heater control unit (GF/GW) – the fan does not work.

⚠ Glitchy central locking – often due to wiring in the doors.

⚠ Burnt contacts in the steering column switches – problems with headlights and windshield wipers.

✅ Advice: check the condition of the wiring and clean the contacts.

5. Body and corrosion

⚠ Thresholds, wheel arches, doors (especially GD, GE) rot.

⚠ The bottom rusts, especially near the rear side members.

✅ Advice: anti-corrosion treatment will extend the life of the body.
