Hyundai i10 1.2 BA

The column-mounted electric power steering system on the i10 can develop faults in the motor or control module, typically after 7-10 years or 80,000-120,000 km. Symptoms include the steering suddenly becoming very heavy or intermittently losing assistance, often with the EPS warning light. Hyundai has acknowledged this on certain VIN ranges. An aftermarket EPS module costs around €300-500, but coding to the car's ECU using Hyundai diagnostic equipment adds labour cost. A full steering column assembly replacement at a dealer runs €1,000-1,200. Independent specialists who can recode refurbished modules offer a middle-ground at €600-800.

The front anti-roll bar drop links and lower arm bushes are known weak points on the second-generation i10. Forum reports consistently describe clunking noises over speed bumps, typically from 50,000-70,000 km onwards. In some cases, bolts securing the front lower arms to the subframe have been found loose. Drop link replacement runs €80-150 per pair including labour. If lower arm bushes have also deteriorated, replacing both front arms costs €200-400 at an independent shop. This appears earlier on the i10 than on some competitors but is an inexpensive repair.

Hyundai officially recognised a problem with rear brakes sticking on the i10, particularly on models with rear disc brakes. When parked in damp conditions, corrosion bonds the pads to the disc surface. On the next drive, owners hear a clonk as the pad frees itself. In more severe cases the brake can remain partially applied, causing the rear wheels to overheat and even produce smoke. Hyundai developed a revised compound brake pad to address the issue. A brake service with new pads costs €80-150. If the discs are scored from repeated sticking, full disc and pad replacement runs €150-300.

Several owners of the 1.2 G4LA report higher than expected oil consumption, particularly on cars with over 100,000 km. The issue is typically traced to worn piston ring sealing or degraded valve stem seals. In mild cases a faulty PCV valve is the cause, which is a cheap fix (€30-50 for the part). Moderate consumption (0.5-1.0 litre per 5,000 km) can be managed by checking oil regularly. In severe cases where consumption exceeds 1 litre per 3,000 km, engine work may be needed: valve stem seal replacement costs around €400-600, while a piston ring job is €1,500-2,500. Regular oil changes with the correct 5W-20 or 5W-30 specification significantly reduce this risk.

The 1.2 four-cylinder has four individual coil packs that can degrade over time, especially if spark plugs are not replaced on schedule. Symptoms include misfires, rough idle, and increased fuel consumption. Valve cover gasket leaks can allow oil to seep into the spark plug tubes, accelerating coil deterioration. A single coil pack costs €25-40 for aftermarket or €50-70 for Hyundai OEM. Replacing all four coils plus spark plugs at an independent shop costs €100-250. If left unaddressed, persistent misfires can damage the catalytic converter, which is a much more expensive repair.

The 4-speed automatic available on the 1.2 is a conventional torque converter unit, but it has a reputation for developing problems over time. Common complaints include delayed gear engagement, jerky shifts when accelerating or decelerating, and transmission slipping. In some cases the torque converter develops shudder. Transmission fluid should be changed every 60,000 km despite some manuals suggesting it is a lifetime fill. A fluid and filter change costs €150-250. If internal components have worn, a gearbox rebuild runs €800-1,500 at a specialist, while a full replacement can reach €1,800-2,500. Manual-equipped i10s are significantly more reliable.
