What Causes a Car to Shake at High Speeds?

1 Answers
MaliaLee
07/30/25 4:11am
Shaking at high speeds is generally caused by component failures or loose assembly leading to body resonance. Here are some common reasons for car shaking: 1. Uneven brake disc surface: Excessive radial runout caused by uneven braking force or misaligned brake pads. 2. Excessive tire pressure: When driving at high speeds on uneven roads, the vehicle shakes noticeably, making it easy for the driver to feel body vibration and pulling. 3. Severe tire wear: Significant imbalance due to uneven wear or large dynamic imbalance causes tires to bounce at high speeds, resulting in body vibration. 4. Engine issues: Usually caused by fuel quality or ignition problems. At high speeds and under heavy load, fuel quality and ignition determine power output. If either is abnormal, it can lead to engine weakness and shaking.

What does BYD powertrain malfunction mean?

BYD powertrain malfunction refers to failures occurring in the entire mechanical arrangement process that transmits the power generated by the engine to the wheels through a series of power transfers. Below are detailed explanations: 1. Causes of malfunction: Incorrect ignition timing or premature ignition causing early combustion and detonation of the air-fuel mixture; misfiring or weak sparks from spark plugs due to ignition system failures; decreased cylinder compression pressure caused by severe wear of pistons, piston rings, and cylinders, leading to increased clearance between them and reduced sealing, resulting in cylinder head leakage; reduced suction due to poor sealing and air leakage in the crankcase. 2. Solutions: Check if the air filter is clogged and clean it if necessary. Ensure the throttle valve opens fully when the accelerator pedal is fully depressed; otherwise, adjust the throttle cable or perform relearning for the pedal position sensor and throttle position sensor. Visit an automotive repair shop for professional servicing.

What are the types of engine oil for cars?

The engine oils for cars include: 1. Conventional mineral oil; 2. Semi-synthetic oil; 3. Fully synthetic oil. The functions of engine oil are: 1. Reducing friction and high temperatures; 2. Cooling and lowering temperature; 3. Cleaning and removing contaminants; 4. Damping and cushioning; 5. Preventing rust and corrosion. The method for changing engine oil is: 1. Lift the vehicle with a jack, locate the drain plug, and loosen it to drain the oil; 2. Remove the oil filter and place a container underneath; 3. Replace with a new oil filter and add new engine oil. Precautions for using engine oil include: 1. The oil level should be slightly below the mark on the dipstick. Engine oil is crucial for the engine, serving the dual functions of lubrication and heat dissipation; 2. Choose engine oil with different viscosities based on the engine's operating conditions. Use lower viscosity oil in colder seasons and higher viscosity oil in warmer seasons.

What is the Difference Between Supercharging and Turbocharging in Automobiles?

Automobile supercharging and turbocharging differ in the following aspects: 1. Charging Methods: Supercharging utilizes the engine's own power to drive a compressor for pressurization; Turbocharging uses the exhaust gases produced by the engine to drive a turbine in the exhaust pipe, which in turn drives a turbine in the intake pipe for indirect pressurization. 2. Pressure Differences: Supercharging is limited by the engine's speed, resulting in lower pressure; Turbochargers operate at extremely high speeds, generating several times more pressure than superchargers. 3. Structural Differences: Superchargers are connected to the engine's crankshaft pulley via a belt, using the engine's speed to drive internal blades to produce pressurized air delivered to the engine's intake manifold; Turbochargers have their turbine housing intake connected to the exhaust manifold, with the exhaust outlet linked to the exhaust pipe, the turbocharger's intake connected to the air filter pipe, and the exhaust outlet connected to the intake manifold, with the turbine and impeller installed in the turbine housing and the turbocharger, respectively.

What is Car Stall?

Car stall refers to the phenomenon where the output speed of the torque converter is zero while the engine is running, meaning the pump wheel rotates while the turbine remains stationary. The causes of car stall include: 1. Throttle cable stuck; 2. Throttle motor jammed; 3. Poor contact of the throttle sensor; 4. Open circuit; 5. Overheating of the engine; 6. Lack of gasoline, engine oil, or coolant. The methods to handle car stall are: 1. Control the direction based on road conditions and speed, shift out of high gear into low gear, and use the handbrake and engine drag to quickly reduce speed; 2. If the vehicle's own mechanisms cannot control the speed, the driver should decisively use rigid parts such as the bumper or body to approach the roadside wall, increasing resistance through friction to achieve forced stopping; 3. When brake failure occurs while going uphill, downshift to medium or low gear in time to maintain sufficient power to reach the top of the slope and stop.

What is the problem if the car door leaks a little rain?

Door leakage may be caused by loose door seals, door deformation, or a blocked drain pipe in the air conditioning evaporator, preventing the drainage of condensation water. The specific details are as follows: 1. Inspection and repair: In such cases, it is recommended to contact the local 4S store for inspection and repair. Alternatively, you can negotiate with the 4S store or the manufacturer. You can report the issue to the relevant department and wait patiently, while keeping your phone and other communication devices accessible for easy contact by the manufacturer's staff. 2. Caused by door leakage: Driving leakage should be caused by door leakage. If the window regulator has been replaced, it may be due to improper adhesion of the door waterproof membrane after the regulator replacement, as the waterproof membrane needs to be peeled off during the regulator replacement. If the waterproof membrane is not properly adhered, heavy rain can cause water to enter the car.
