Does turning the steering wheel all the way have an impact on the car?

Turning the steering wheel all the way does have an impact on the car. For most vehicles with hydraulic power steering today, turning the steering wheel to its limit can indeed cause some issues. The greater the angle the steering wheel is turned, the higher the oil pressure in the power steering pump becomes. When the steering wheel is turned all the way, the power steering pump operates under high load. If this happens frequently, it can lead to premature aging and damage, resulting in a heavier steering wheel and reduced steering power. Turning the steering wheel fully counterclockwise or clockwise is referred to as "turning the steering wheel all the way," which is used in cars and other vehicles for short-distance maneuvers, allowing the vehicle to complete significant turns with minimal movement.
Having driven for decades, I've seen many friends who like to turn the steering wheel to the full lock when making turns. This practice indeed has adverse effects on the car. It mainly adds extra burden to the steering system, causing components like the steering gear and power steering pump to overheat and wear out due to excessive pressure, especially in hydraulic power steering models where the pump is prone to making strange noises or even failing. Tires also suffer from uneven wear, shortening their lifespan. Additionally, suspension components subjected to extreme tension over time can deform, leading to misalignment and affecting handling. In fact, it's best to leave a little room when turning instead of going to full lock. Gentle driving helps protect your car and reduces the frequency of repairs. Regularly checking steering components is also a good habit.
As an automotive enthusiast, I often discuss driving techniques, and "turning the steering wheel to full lock" is a common misconception. Turning it all the way to the end puts extreme pressure on the tie rods and ball joints, increasing mechanical fatigue. It also causes significant impact on the power steering system—hydraulic power steering pumps may overheat, and electric power steering motors bear heavier loads, accelerating aging. Tire sidewalls and treads wear out faster, especially noticeable on bumpy roads. Leaving some margin when turning not only reduces wear but also improves steering precision and avoids sudden issues. By the way, it's better to turn the steering wheel gently when parking—don't force it. Making this a habit will keep your car running longer and smoother.
I just got my driver's license, and my instructor reminded me not to turn the steering wheel all the way when learning to drive. Indeed, this can cause damage to the car. Components of the steering system are prone to wear, such as increased stress on gears and bearings. Especially for older cars, power steering might fail earlier. Tires also wear unevenly, reducing their lifespan. It's better to leave some margin when turning to protect the vehicle. After practicing, I've changed this habit.
