In freezing weather, a car may fail to start for a range of reasons, as the cold slows every system and drains energy from essential components. The battery and the fuel system are typically the first to show trouble, according to Alexander Goman, an expert with the Fit Service car service network. He explains that extreme cold places extra strain on starting with the engine and can reveal weaknesses in the most common winter culprits. (Source: Fit Service expert Alexander Goman)
When temperatures dip below about minus 20 degrees Celsius, the battery loses charge more quickly and struggles to deliver the surge needed for a reliable start. This is especially true for drivers who make short trips or stop-and-go runs, because the alternator has little opportunity to recharge the battery between uses. In the morning chill, the battery can appear unable to supply sufficient energy, causing the engine to stubbornly refuse to crank. As a result, drivers often face repeated no-start situations until warmth returns or a jump start confirms the issue. Regular winter routines include checking battery health, cleaning terminals, and ensuring cables are secure to minimize these interruptions. (Source: Fit Service expert Alexander Goman)
Another frequent winter problem centers on spark plugs. When cold weather arrives, old or fouled plugs can fail to ignite the air-fuel mixture consistently. Drivers may try to start the engine and only afterward visit a service station once the failure becomes obvious. Additionally, a dirty throttle body or clogged injectors can hamper starting and running performance. Clean intake components at reasonable intervals—roughly every 20,000 to 30,000 kilometers—to maintain smooth starts. This upkeep is simple and can prevent stubborn starting problems in frosty mornings. (Source: Fit Service expert Alexander Goman)
Fuel delivery also plays a critical role in winter starts. Some vehicles stall or refuse to start when the gasoline is of questionable quality or when seasonal blends perform differently in cold weather. The expert recommends opting for high-quality fuel during winter months, along with keeping the fuel system clean and free of contaminants. In challenging weather, fuel quality can determine whether a vehicle fires up promptly or waits for extra warmth. (Source: Fit Service expert Alexander Goman)
Historically, severe frosts have driven more people to seek service help. In recent winters, calls to car services in Russia rose by a notable margin, reflecting a broader pattern of increased demand during cold snaps. This trend underscores the importance of proactive winter maintenance and timely diagnostics to avoid unexpected breakdowns when temperatures plummet. (Source: Fit Service expert Alexander Goman)
