Fuel starvation can cause a car to stall when turning left or right, particularly during tight or low-speed maneuvers. As the vehicle navigates a turn, the movement of fuel inside the tank can affect its flow toward the fuel pump. If the fuel level is low or if the fuel lines are restricted or kinked, the fuel supply to the engine can be compromised, resulting in a stall.
Loss of Oil Pressure
Oil is essential for lubricating engine components and maintaining proper oil pressure. If the oil level is too low or if there's a leak in the oil system, it can lead to insufficient oil pressure. When turning, the lateral forces acting on the vehicle can temporarily restrict oil flow to critical engine parts, causing a loss of oil pressure and engine stalling.
Failing Power Steering Pump
A faulty power steering pump can also cause a car to stall when turning. When the power steering pump fails or experiences issues, it may draw excessive electrical power from the vehicle's electrical system, including the ignition system. This excessive power draw can lead to a drop in available voltage, which can disrupt the ignition process and cause the engine to stall.
Fuel System Issues
In fuel-injected vehicles, a failing fuel injector can cause a car to stall when turning. A malfunctioning injector may not deliver the appropriate amount of fuel to the engine, particularly under specific load conditions like turning or accelerating. This disruption in the fuel supply can cause hesitation, rough running, and in severe cases, stalling.
Electrical Problems
Electrical issues, such as loose or corroded wiring connections, faulty sensors, or a weak battery, can also contribute to stalling problems during turns. As the vehicle's weight shifts and components move during a turn, electrical connections may experience intermittent disruptions or short circuits, affecting engine performance and potentially leading to a stall.
Steering System Problems
A vehicle with alignment issues or worn steering components may experience additional resistance and increased effort when turning. This additional resistance can strain the engine and potentially cause it to stall, particularly if the engine is already under stress.
It's important to have a qualified mechanic diagnose the exact cause of the stalling issue, as it could indicate underlying problems that may need attention to ensure safe vehicle operation.
