What Causes the Steering Wheel of a New Car to Lean to the Left?
2 Answers
New car steering wheels are supposed to be straight, so a left-leaning steering wheel indicates a quality issue, possibly due to improper assembly during the steering wheel installation. Below are the reasons why a new car's steering wheel may lean to the left: 1. Steering gear malfunction: If the car's steering gear was not properly installed during assembly or if the central shaft of the steering gear has come loose, it can cause the steering wheel to lean. The reasons for steering gear issues are complex and require professional inspection at a repair shop or 4S store. 2. Uneven tire pressure on both sides of the car: If the tire pressure is uneven on both sides of the car, the vehicle will tend to pull toward the side with lower tire pressure. It is important to regularly check the tire pressure, which is generally recommended to be around 2.5 bar. 3. Different camber angles on both sides of the car: After replacing or repairing tires, it is essential to perform a four-wheel alignment promptly. Different camber angles on both sides can also cause the vehicle to pull to one side and may increase fuel consumption.
I've encountered the issue of a new car's steering wheel pulling to the left several times. Initially, I thought it was due to driving habits, but later discovered that the common cause is inaccurate wheel alignment. New cars often have significant adjustment errors from the factory, especially in mass-produced models. Loose or worn suspension system bolts can also cause steering deviation. Another factor is uneven tire pressure - if the left tire pressure is lower, it increases pulling force and automatically drags in that direction. I recommend starting with basic checks: use a tire pressure gauge to ensure all four tires have equal pressure (manufacturer recommended values are usually on the door label). If the pulling persists after adjustment, definitely return to the 4S dealership for professional alignment - most new cars receive free repairs for this. Don't ignore this small issue, as long-term neglect leads to uneven tire wear, higher repair costs, and impacts both driving safety and comfort.
