Generally, if a car is parked outside during heavy rain, there shouldn't be much of a problem as most cars have good sealing. However, parking a car outdoors during heavy rain depends on the location; avoid low-lying areas to prevent flooding. It's also important to regularly check the vehicle's drainage channels for blockages. Places to avoid parking during heavy rain: 1. Low-lying areas: The main concern during heavy rain is urban flooding, which can lead to water accumulation in vehicles. Therefore, parking location matters. First and foremost, avoid parking in low-lying areas as these are prone to water accumulation. Examples include underground parking lots, under overpasses, downhill roads, and potholed areas—all posing potential safety hazards. 2. Under trees: Most car owners are aware of the risks of parking under trees. Heavy rain often comes with strong winds, and it's not uncommon for trees to fall overnight, damaging cars with branches or trunks. A quick online search reveals many such incidents, from shattered windows to scratched car bodies. 3. Near hazardous structures: Similar to parking under trees, parking near potentially dangerous structures like billboards, utility poles, or unstable walls during windy weather poses safety risks, as loose or falling objects can damage the car.

I've been driving for over thirty years, and heavy rain indeed causes many harms to vehicles. Rain can fog up the windshield, reducing visibility and increasing the risk of collisions. The braking system is prone to skidding on wet roads, raising the chance of accidents. Prolonged exposure to rain allows acidic components in the water to corrode the car's paint and accelerate rusting, especially affecting the undercarriage and doors. Once, I almost had an accident due to brake failure during a heavy rainstorm. Since then, I always check the windshield wipers before rain to ensure they work properly, replace tires with deeper treads for better drainage, drive at reduced speeds with steady control, turn on fog lights for enhanced safety, and avoid sudden braking or acceleration.

How Long Can a 2003 Car Still Be Driven?

2003 model year sedans can be driven indefinitely as long as they are properly maintained and pass annual inspections, as there is no specific mandatory retirement age. According to Article 5 of the 'Mandatory Vehicle Retirement Standards', small and micro non-commercial passenger vehicles, large non-commercial sedans, and wheeled special machinery vehicles have no usage lifespan restrictions. Additional reference materials are as follows: 1. Vehicle inspection data: Apart from body aging, vehicles may also face elimination due to failing to meet emission standards. Various regions have gradually tightened restrictions on emissions, with the 2017 requirement to phase out vehicles that do not meet emission standards. Whether emissions meet standards is primarily based on vehicle inspection data, with the smoke opacity value determining compliance. 2. Non-compliant vehicles: If repairs still cannot meet emission limits, the transportation certificate will be revoked by authorities. Currently, common technologies in China to make high-emission vehicles meet smoke opacity standards include installing DPF (Diesel Particulate Filter) and adding water-assisted engines.

Why Do 4S Shops Want to Replace Car Lights for Owners?

Some 4S shops use non-original parts as original parts. Since the cost of non-original parts is relatively low compared to original parts, the price difference is significant. 4S shops use non-original parts to profit from this price gap. Here is additional information: 1. 4S Shop: A 4S shop, fully known as Automobile Sales Service Shop 4S, is a sales outlet that integrates car sales, maintenance, parts, and information services. 4S shops are invested and built by dealers according to the standards set by car manufacturers. They feature unified interior and exterior designs, require huge investments often exceeding tens of millions, and are luxurious, grand, and comfortable. They are authorized to sell only a single brand of cars. 2. Methods to Judge Headlights: Compared to original headlights, non-original headlights vary in quality, with many flaws at the edges and unclear engraved logos. Due to insufficient manufacturing standards, the gaps between non-original headlights and the car body are uneven, with significant left-right deviations. Additionally, non-original headlights have poorer lighting effects, longer reaction times, and may even exhibit uneven brightness between the left and right sides.

Is the maintenance cost of BMW X1 high?

The post-warranty maintenance costs for BMW vehicles are relatively expensive. During the warranty period, repairs are free, but after the warranty expires, the maintenance costs can be very high, significantly more expensive than those of regular joint-venture vehicles. The following are the steps to handle an overheated BMW engine: 1. Immediately reduce speed: After slowing down, drive the car to a safe area on the roadside and park it; 2. Do not turn off the engine immediately: After parking, do not shut down the engine right away, as excessively high water temperature can cause the pistons, cylinder walls, cylinders, crankshaft, etc., to overheat, thinning the engine oil and losing its lubricating effect. Turning off the engine can lead to the detachment of some soft metals and may even cause cylinder seizure; 3. Let the engine idle for a few minutes: Adjust the air conditioning to the heating mode, set the fan to maximum speed, and open the hood to help dissipate heat from the engine. Only turn off the engine after the water temperature has dropped.

What happens when the body control module fails?

A malfunctioning body control module can cause some electrical components on the vehicle to stop working properly, such as turn signals, windshield wipers, power windows, and door locks. For automatic transmission vehicles, specific issues may include the trunk failing to open, the key being stuck in the ignition, the P gear being locked, brake lights not illuminating (though the high-mounted brake light may still work), windshield washer fluid not spraying, and the cigarette lighter not functioning. Below is an introduction to the gears of an automatic transmission car: 1. L Gear: Low gear, which limits speed. When climbing a hill, shifting into this gear maintains high RPMs at a low gear ratio. 2. S Gear: Sport mode, where the transmission can shift freely but delays shifting to keep the engine at higher RPMs for extended periods, allowing the car to move at high RPMs in low gears for longer durations. 3. D Gear: Drive gear, used for normal forward movement of the car. 4. N Gear: Neutral gear, used during brief stops. 5. P Gear: Park gear, used when parking to engage the parking brake and prevent the car from rolling. 6. R Gear: Reverse gear, used for backing up. However, R gear should only be engaged when the vehicle is completely stopped; shifting into R while the car is still moving slowly can cause severe damage to the transmission.
