What is the reason for the sudden heaviness of the Lavida steering wheel?

The reason for the sudden heaviness of the Lavida steering wheel is dirty power steering fluid. In this case, the owner should promptly replace it with new power steering fluid. Power steering fluid is a special liquid used in the car's power steering pump, which, through hydraulic action, makes the steering wheel very light, similar to automatic transmission fluid, brake fluid, and shock absorber fluid. The Lavida is a compact car equipped with a 1.5L L4 engine, naturally aspirated, with a maximum horsepower of 113ps and a maximum torque of 145nm. The dimensions of this car are 4670mm in length, 1806mm in width, and 1474mm in height, with a wheelbase of 2688mm. The body type is a 4-door, 5-seat sedan.
I drove a Lavida for commuting for ten years, and when I encountered the sudden heavy steering issue, I immediately thought of a power steering system failure. The Lavida typically uses electric power steering; if there's a problem with the control module or the motor fails, steering becomes as tough as pulling an iron block. Low tire pressure can also make the steering wheel heavy, especially if the front and rear tire pressures are uneven, making it hard to drive straight. At the time, I checked under the car and found no oil stains, indicating it wasn’t a hydraulic system leak. Another time, I found that a faulty sensor could also cause power steering failure. Later, at the repair shop, the mechanic used a diagnostic tool to detect motor overload, and after replacing the part, it was fixed. Pay attention to the steering feel at low speeds during daily driving, and regular maintenance of the steering system can prevent this trouble. I suggest not delaying repairs, or it could be disastrous on the highway.
When helping out at the repair shop, I often encounter Lavida owners complaining about heavy steering. The main causes could be a faulty power steering pump or a burnt-out electric power steering motor, leading to system failure. Insufficient tire pressure or severe wear can also affect steering effort—it's best to check each tire's pressure with a gauge and top up if low. Loose wiring harnesses in the control module or aging relays are also common culprits, requiring removal of the lower steering wheel cover to inspect connector cleanliness. Voltage instability due to battery or alternator issues can also worsen steering. I've seen owners handle simple checks like tire pressure themselves, but complex issues need professional tools—don't compromise safety to save money.
