Does running out of fuel affect a new car?

Running out of fuel in a new car does have an impact. When a car completely runs out of fuel, two phenomena may occur: the loss of steering power and brake power, eventually leading to the vehicle stalling completely. Loss of steering power: Most vehicles commonly use mechanical and electronic hydraulic power steering. When the engine suddenly stalls, the power steering pump stops working, making the steering wheel heavy and difficult to turn. For electric power steering, the steering is assisted by an electric motor. Running out of fuel and engine stalling does not mean the entire vehicle loses power; the power steering motor can still function, so there is no impact. Loss of brake power: Most car braking systems use vacuum assist, which is generated by the engine. After the engine stalls, the vacuum booster still retains some vacuum, ensuring the first few brake applications have assistance. Once the engine stalls and the vacuum is depleted, the brake pedal becomes hard, making braking difficult.
A few days ago, I took my new car out, only to run out of gas and stall on the roadside. Upon reflection, driving a new car until it's out of fuel is actually a serious issue. The most dangerous part is the risk of overheating and damaging the fuel pump, as the pump relies on gasoline for cooling and heat dissipation. Without fuel, the pump can overheat and burn out, leading to expensive repairs and delays. The engine can also be affected, such as incomplete combustion of residual oil during idling, which can cause carbon buildup and clog the fuel injectors—particularly harmful to a new engine, especially during the break-in period. Such strain can accelerate internal component wear and shorten the overall lifespan. If this happens frequently, it may even corrode the fuel lines, increasing long-term failure risks. So now I've developed the habit of refueling before the tank drops below a quarter full—it's much better than breaking down on the road and doesn’t cost much.
Last time I saw my friend's new car running until the fuel gauge turned red, yet he kept pushing it. Eventually, the engine suddenly stalled on the highway, which really gave me a scare. From a safety perspective, an empty tank doesn't just leave the car stranded—it's even more troublesome on busy roads where it can cause rear-end collision risks or lead to impatient honking, especially on curves or steep slopes where losing control becomes dangerous. Moreover, if air enters the fuel line after restarting, the engine may fail to start until the air is slowly purged, wasting time and increasing the chance of mishandling. Newer car systems are more sensitive, and fuel efficiency can also take a hit—expect slightly higher consumption after a few such episodes. In short, keeping the tank above the warning line and refueling before the low-fuel light comes on is a simple way to avoid these risks.
As a new car owner, I initially didn't pay attention to the fuel level for convenience, only realizing the severe consequences after running out of gas. After the car stalled, the fuel pump overheated and nearly got damaged. The repair shop said fixing it would cost several hundred dollars, and the engine also accumulated carbon deposits affecting performance. Later, it became difficult to start the car every time, the fuel line got clogged, and the car felt sluggish with increased fuel consumption. The new car maintenance manual clearly warned not to mess with the fuel level during the break-in period. Now I've developed the habit of refueling in advance, and setting a reminder on my phone is quite practical. Honestly, running out of fuel isn't worth it—costly and frustrating.
