Generally speaking, the electronic parking brake is not prone to malfunction. However, if the car experiences severe power loss, the electronic parking brake may fail to function due to insufficient power. The electronic parking brake is a technology that uses an electronic system to control the vehicle's parking brake, achieving the same effect as a mechanical handbrake but with a different control method. Its advantages include saving the space occupied by a mechanical handbrake, creating more central console space; simple operation and effort-saving; and adding multiple functions such as auto start-stop and hill-start assist. More details are as follows: 1. Activating the electronic parking brake: When the car is stopped, shift to P or N gear, press the brake pedal, and pull up the electronic parking brake switch until the indicator light comes on. If the car is turned off without activating the electronic parking brake, most vehicles will automatically engage the electronic parking brake. 2. Deactivating the electronic parking brake: Press the electronic parking brake switch while holding down the brake pedal. When the indicator light turns off, it means the electronic parking brake is deactivated.

Having driven for many years, I find electronic parking brakes quite reliable in modern cars—far more durable than old-fashioned cable handbrakes, since they operate via motors and circuits without mechanical wear parts. But claiming they never fail is unrealistic. I once experienced a minor issue: the motor occasionally jammed during summer heat, causing the e-brake to be unresponsive, later traced to dirty sensors triggering errors. If the battery is low or circuits get wet, the system will trigger a warning light, requiring prompt attention to prevent parking slippage. Overall, electronic parking brakes are smartly designed with long lifespans, but being electronic components, they carry slightly higher risks—repairs can cost hundreds or even thousands. Regular battery maintenance and system warning checks significantly reduce failure odds. Use them normally, avoid extreme conditions, and for used cars, a professional inspection ensures safety.

What Causes Water Leakage in the Car's Passenger Side During Rain?

Water leakage in the car cabin can be attributed to the following reasons: 1. Clogged sunroof drainage holes: Sunroof drainage holes are prone to blockage by leaves and dust. Once clogged, rainwater cannot drain promptly during rain, leading to seepage into the vehicle. 2. Aging of the sunroof's rubber seal: Rubber components harden and deteriorate over time. When the sunroof's rubber seal ages, its sealing capability diminishes, resulting in leaks during rainy weather. Additionally, using high-pressure water jets or strongly acidic/alkaline cleaners during sunroof maintenance can deform and accelerate the aging of the rubber seal. 3. Blocked air conditioning drainage hole: During operation, the car's air conditioning system generates condensate water in the evaporator. If the drainage hole is blocked, this condensate water may leak from the passenger side.

What types of throttle position sensors are there?

Throttle position sensors are installed on the throttle body and are actuated by the throttle shaft. They can be divided into three types: potentiometer type, contact type, and comprehensive type. The throttle position sensor is also known as the throttle opening sensor or throttle switch. Relevant information about the throttle position sensor is as follows: 1. The main function of the throttle position sensor is to detect whether the engine is in idle condition or load condition, and whether it is in acceleration or deceleration condition. It is essentially a variable resistor and several switches installed on the throttle body. 2. The rotating shaft of the resistor is linked with the throttle. It has two contacts: the full-open contact and the idle contact. When the throttle is in the idle position, the idle contact closes and sends an idle condition signal to the computer.

Should You Use Internal or External Air Circulation for Car Heating in Winter?

In winter, it is recommended to use internal air circulation for heating. There are two methods to operate the air conditioning: First, turn off the AC button, wait until the vehicle starts and the water temperature rises to the normal level, then press the AUTO button on the air conditioning system. Set the temperature to the desired level, and the air conditioning will automatically maintain the set temperature. Here is some relevant information about the car air conditioning's internal and external circulation: 1. Internal circulation, as the name suggests, recirculates the air inside the car. With the doors and windows closed, it only heats the air inside the vehicle, resulting in a faster and more fuel-efficient heating effect. 2. External circulation draws in outside air and expels the air inside the car, keeping the interior air fresh. In winter, when the outside temperature is low, using external circulation will continuously bring in cold air, hindering the rise in temperature inside the car.

Consequences of Mixing Alcohol and Gasoline?

Alcohol and gasoline can be mixed. Alcohol can dissolve gasoline. Alcohol molecules consist of a hydroxyl group connected to an ethyl group. The ethyl group is an oil-loving (lipophilic) group, while the hydroxyl group is a water-loving (hydrophilic) group, which is why alcohol can dissolve gasoline. Below are some relevant details: Gasoline is composed of over 99% carbon and hydrogen, along with some aliphatic and naphthenic hydrocarbons. When exposed to air, it can produce some gummy substances. Theoretically, gasoline hardly deteriorates if air is completely excluded. Modern gasoline contains antioxidants, and conservatively, it can be stored for about 8 months. Some regions now use ethanol gasoline, which is a blend of 90% regular gasoline and 10% fuel ethanol. Due to the 10% ethanol content, ethanol gasoline has a shorter shelf life, lasting up to one month at most. Comparing vehicles from regions that consistently use ethanol gasoline with those from regions that alternately use pure gasoline and ethanol gasoline, there are noticeable differences in fault phenomena and distribution of fault locations. Alternating use can easily lead to fuel leakage and exceedance of emission standards. It also increases the likelihood of engine component and EGR system failures, while other aspects show no significant differences. However, vehicles that alternate between pure gasoline and ethanol gasoline exhibit fewer lubrication system and three-way catalytic converter faults compared to those that use ethanol gasoline exclusively.

What is the Difference Between Four-Wheel Drive and Rear-Wheel Drive?

Four-wheel drive (4WD) means power is delivered to all four wheels, while rear-wheel drive (RWD) means power is delivered only to the rear wheels. Differences: Nature: A 4WD vehicle has a drivetrain that allows all four wheels to receive power simultaneously through front and rear differentials. RWD vehicles rely solely on the rear wheels to provide driving force. Characteristics: Most trucks and some buses use a front-engine, rear-wheel-drive layout. 4WD vehicles, as the name suggests, can deliver power to all four wheels. Advantages: Front-engine, rear-wheel-drive vehicles offer superior traction when starting, accelerating, or climbing on well-paved roads because the load on the drive wheels increases (i.e., the adhesion pressure on the drive wheels increases). 4WD vehicles generally have better engine displacement and can effectively reduce power loss.

How many engine displacements does the Lexus ES have?

The Lexus ES has six engine displacements: 2.0L, 2.4L, 2.5L, 3.0L, 3.3L, and 3.5L. Engine displacement, also known as swept volume, refers to the total volume of air and fuel mixture drawn into the combustion chamber during one complete engine cycle. Generally, engines with larger displacements produce higher power output and stronger performance, but they also tend to consume more fuel. Below are some reasons why a car's fuel consumption may increase: 1. Temperature fluctuations affecting fuel consumption are normal. In winter, lower temperatures typically lead to higher fuel consumption, often comparable to the consumption when using air conditioning in summer. This is because colder temperatures cause the engine to dissipate more heat. To maintain a stable operating temperature, the engine burns more fuel to generate heat, which is wasted rather than used for work, thus increasing fuel consumption. Additionally, winter warm-up times are longer, requiring more time and fuel to reach normal operating temperature. 2. Lack of regular maintenance, such as dirty engine oil and air filters, can also increase fuel consumption. Dirty oil reduces lubrication, increasing resistance in the engine's moving parts and requiring more energy to overcome it, leading to higher fuel consumption. A clogged air filter restricts airflow, forcing the engine to work harder to draw in air and resulting in incomplete combustion, where some fuel is expelled unburned. Consequently, more fuel is needed to cover the same distance. 3. Worn-out spark plugs. Spark plugs are often overlooked, with some drivers not replacing them even after 100,000 kilometers. Although worn spark plugs may still function, their reduced ignition energy causes delayed ignition, missing the optimal timing. For example, if the spark plug fails to ignite the fuel when the piston is near top dead center, ignition may occur as the piston moves downward, leading to power loss and inefficient energy use. This also results in incomplete combustion, further increasing fuel consumption.
