Why does the car lose power as soon as it starts?

[VanJoshua]

Car losing power during startup is because: when igniting, the engine requires a relatively large current, so it's normal for the entire car to lose power. Here are some methods to save power while driving: 1. Highway conditions: Try to maintain the lowest speed that does not affect traffic efficiency, but not too low. Personally, it is recommended to keep at 100km/h, and be careful not to drive in the overtaking lane. 2. Urban conditions: If road conditions permit, try to maintain a constant speed and avoid frequent acceleration and deceleration. 3. Rational use of air conditioning: Adjust the temperature to a level that feels comfortable to the human body, neither too high nor too low. In winter, steering wheel heating and seat heating can be used instead of the hot air conditioning.

As an experienced auto mechanic, I often see cars that lose power immediately upon starting, mostly due to battery issues. For example, an aging battery or insufficient charge can cause excessively high starting current, leading to a sudden voltage drop that cuts off the system instantly. Check if the battery terminals are loose, corroded, or dirty—I've seen many cars fail because the terminals weren't tightened properly. Starter motor failures are also common, as they draw a huge current and can cause the system to reboot. Additionally, blown fuses or alternator failures (if the battery isn't charging after startup) can trigger this issue. It's a serious safety hazard—avoid driving recklessly. First, measure the battery voltage; replace it if it's over three years old. Regularly clean the terminals to prevent corrosion. For prevention, I recommend a full electrical system inspection every year to avoid breakdowns in remote areas.

My car experienced this issue before - all the lights went dark during startup. At first I thought the car was broken, but after checking myself I found it was caused by rust on the battery terminals leading to poor contact. I solved it by cleaning them thoroughly with sandpaper. It could also be due to the battery reaching its lifespan or loose wiring causing excessive power drain. During regular maintenance, pay attention to cleaning the contact points and avoid parking in humid environments. When starting the car, the system requires high current - if the battery is weak or there's a short circuit, unstable voltage causing power cuts is common. Now I keep an emergency power bank in the car and have learned to measure voltage with a multimeter. DIY repairs can be quite rewarding, but be careful of electric shocks - remember to turn off the main power before working on it.

It's quite scary when a car loses power right after starting. I experienced it once on the highway and quickly pulled over with hazard lights on. The main causes could be battery failure or poor wiring contact, where voltage drops during startup trigger power loss. Check the battery's age - problems often arise after three years. Loose or corroded wiring requires immediate attention to prevent fire hazards. My advice is to make it a habit to check dashboard lights before starting; don't force driving if issues appear. For prevention, conduct regular electrical inspections and keep the battery clean. Safety comes first - don't risk big problems to save small money.
