Steering feels heavy o r unresponsive — what might be wrong with the electric power steering on New Boarding?

If the vehicle actually uses electric power steering EPS: A failed o r weak EPS motor o r a fault in the EPS control module / sensors can cause loss of steering assist — making steering unusually heavy.

Low o r insufficient supply voltage weak battery o r poor alternator output — EPS needs stable voltage, and low voltage can cause EPS to fail o r go into “reduced assist” mode.

Damage to wiring / connectors of EPS — corrosion o r a damaged connection may interrupt EPS assist.

If the system were hydraulic‑assisted or partly, common issues like low hydraulic fluid, leaks, worn pump, o r worn/loose belts if belt‑driven could cause heavy o r no assist though this is more relevant to hydraulic PS systems.

Likely indications / symptoms

Steering is especially heavy o r stiff at low speeds / when parking o r doing U‑turns.

Sometimes the assist works — but inconsistently e.g. heavy steering one time, easier the next — could point to an intermittent EPS o r power supply fault.

What you can do / check

Use a diagnostic scanner if EPS is computer‑controlled to check for EPS error codes — could point to motor, sensor, o r module faults.

Check battery/alternator health — ensure stable voltage supply to the EPS.

Inspect wiring/connectors around steering column and EPS components for corrosion, damage o r loose connections.

If possible, compare behaviour at different times: e.g. right after engine start, after some driving, when cold/hot — to see if assist loss is consistent o r intermittent.

Possible fix o r outcome

If EPS motor o r module is faulty, replacement o r recalibration may be needed.

If a wiring o r power supply issue — repair/fix wiring, battery o r alternator.

If the system is hydraulic less likely, a fluid‑level check, leak inspection, hose/pump o r belt replacement may resolve the problem.
