Is Steering Wheel Vibration Normal When the Air Conditioning is On?

Steering wheel vibration when the air conditioning is on is not normal. The specific reasons for steering wheel vibration when the air conditioning is on are as follows: Dirty Throttle Body: In this case, the engine will vibrate slightly, but it is usually not noticeable. However, once the air conditioning is turned on, the engine load increases, and the vibration intensifies. The solution is to clean the throttle body and simultaneously check whether the condenser is dirty or blocked and if there are any issues with the ignition system. Damaged Air Conditioning Compressor: This is the most severe cause because once it is damaged, there is basically no possibility of repair, and it can only be replaced. Generally, older cars over 6 years old may experience this issue, while new cars rarely do. Along with the vibration, another accompanying problem is that the air conditioning does not blow cold air, but the blower keeps running.

Slight steering wheel vibration when the AC is on is common, especially in older car models, as the activation of the AC compressor increases engine load and may cause some vibration. I've noticed this issue while driving, such as when the steering wheel shakes slightly when the cold air is on in summer, but it's usually not a big deal. If the vibration is very slight and doesn't affect driving, it's generally normal. However, be wary of severe shaking, which could be caused by worn engine mounts or loose belts, in which case it's time to have it checked at the garage. To avoid long-term issues, check the engine firmware, ensure the cooling system is functioning properly, and maintain vehicle health.

The steering wheel shaking when the AC is on worries me, especially when the speed is steady but the shaking gets worse—this is a driving safety issue. Turning on the AC increases engine load, and if the compressor isn’t working smoothly or there’s an issue with the engine mounts, it can cause significant steering wheel vibration. I recommend paying attention to the frequency of the shaking. If it affects steering, pull over as soon as possible and have a professional shop inspect it. Minor shaking is common in hot weather, but safety comes first—don’t ignore it. Maintaining a steady speed can also help reduce vibrations.

Steering wheel vibration when the AC is on usually occurs because the air conditioning system draws some power from the engine. When the compressor kicks in, the sudden increase in engine load can cause slight vibrations, especially at low RPMs. If the engine mounts are worn or the belts are loose, the shaking may worsen. Minor vibration is normal, but severe shaking requires component inspection to prevent long-term damage to the vehicle's core functions. Ensuring smooth driving is key.

Will I Be Fined for Driving with the Trunk Open?

Driving with the trunk open is considered a traffic violation, and the vehicle may be stopped by traffic police and penalized. Generally, this results in a fine, but the driver may only receive a warning without any points deducted. Upon being reminded by the traffic police, the driver must promptly close the trunk securely. According to Article 9 of the 'Measures for the Scoring Management of Road Traffic Safety Violations,' if the trunk being open blocks the license plate, it constitutes the violation of 'intentionally obscuring the license plate.' In such cases, the traffic management authorities will impose a fine and deduct 12 points. Additionally, an improperly closed trunk can obstruct the driver's visibility and affect safe driving, potentially interfering with other vehicles and pedestrians on the road. The traffic police may impose a fine and deduct three points, as this situation can easily lead to traffic accidents and poses significant safety hazards. Therefore, the traffic police may impose stricter penalties on the driver to prevent such behavior from recurring. According to Article 62 of the 'Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China,' the following acts are prohibited while driving a motor vehicle: driving with the doors or trunk not properly closed; hanging or placing items within the front or rear windows that obstruct the driver's view; making or receiving handheld phone calls, watching TV, or engaging in other activities that hinder safe driving; stalling or coasting in neutral on steep slopes; or throwing items onto the road. If there are items in the trunk, they may be lost when driving on bumpy roads, leading to financial losses. If these items cause damage to vehicles behind, the driver may also be liable for repair costs.

What is the 0-100 km/h acceleration time for the Sylphy?

According to official data, the 1.6L Sylphy model has a 0-100 km/h acceleration time of 12.1-12.2 seconds. Factors affecting a vehicle's 0-100 km/h acceleration time are as follows: Torque: Torque, in layman's terms, represents how much force is available. The greater the torque, the more force is available to propel the vehicle, resulting naturally in faster acceleration. The Audi R8 has a maximum torque of 570 Nm and a 0-100 km/h acceleration time of 3.1 seconds. The Sylphy has a torque of 155 Nm and a 0-100 km/h acceleration time of 12.1 seconds. Transmission efficiency: The transmission is the medium for transferring power and inevitably involves power loss. The higher the transmission efficiency, the better the acceleration performance. Generally, transmission efficiency ranks as follows: manual transmission > dry dual-clutch transmission > wet dual-clutch transmission > AT transmission > CVT transmission. The Sylphy is equipped with a CVT continuously variable transmission. Power-to-weight ratio: The relationship between horsepower and vehicle weight is called the power-to-weight ratio (unit is Hp/T). The higher the power-to-weight ratio, the faster the acceleration. The Audi R8 has a power-to-weight ratio of 373 Hp/T and a 0-100 km/h acceleration time of 3.1 seconds. The Sylphy has a power-to-weight ratio of 103 Hp/T and a 0-100 km/h acceleration time of 12.1 seconds.
