Can CVT Shudder Be Left Unrepaired?

Whether it needs repair depends on whether it affects driving. Some cars may experience shaking when accelerating sharply, in which case repair is necessary. The advantages and disadvantages of CVT continuously variable transmission are as follows: 1. Advantages: (1) Since there are no transmission gears like in a conventional automatic transmission, the accompanying gearshift shock is eliminated, resulting in linear power output from the CVT transmission, which provides a very smooth driving experience. (2) The CVT transmission system theoretically allows for an infinite number of gears, offering greater flexibility in gear settings. It is easier to achieve the balance between gear ratio, speed ratio, performance, fuel consumption, and exhaust emissions in traditional transmission systems. (3) The mechanical efficiency and fuel economy of CVT transmission are significantly better than those of conventional automatic transmissions, second only to manual transmissions, offering much better fuel efficiency. 2. Disadvantages: (1) Compared to traditional automatic transmissions, CVT has not been used in cars for very long, and there are still few cars equipped with CVT in the domestic market. This means that the maintenance cost of CVT is relatively high, and improper operation increases the likelihood of problems. (2) CVT transmissions can only handle limited torque. Except for the Multitronic transmission in the Audi A6, most CVT transmissions cannot handle heavy loads and are only suitable for small cars with engine displacements of around 1 to 1.5 liters.

After buying my car, I also experienced CVT shuddering issues. At first, I thought it was nothing and kept driving, but after a few weeks, the shaking became worse and gear shifts weren't smooth anymore. This kind of shuddering could stem from CVT belt wear, insufficient fluid, or sensor malfunctions. Ignoring it will accelerate transmission damage. If left unrepaired for a long time, at best you'll face higher fuel consumption and poor driving experience, at worst it may lead to major repairs or even sudden breakdowns while driving, increasing safety risks. Now I always advise friends to get professional inspections as soon as they notice abnormalities. Changing fluids or making adjustments costs little compared to expensive repairs later.

How to Solve the Abnormal Noise When Pressing the Accelerator?

Abnormal noise from the fuel pump motor requires replacing the fuel pump. For abnormal noise from the throttle, cleaning the throttle is necessary; if the motor is damaged, the throttle needs to be disassembled to replace the servo motor. If the abnormal noise is caused by poor lubrication of the accelerator pedal bearing, you can apply grease to the bearing for lubrication. If the clutch release bearing is damaged, remove the clutch and replace the release bearing.

How to Reset the Tire Pressure Light on a 2018 Hyundai ix25?

The method to reset the tire pressure light on a 2018 Hyundai ix25: First, turn on the ignition, then press and hold the tire pressure monitoring reset button. After hearing a "ding" sound, release the button. The tire pressure monitoring system will then store the current normal tire pressure data, automatically clear the previous data, and finally, the warning light on the dashboard will turn off, indicating the tire pressure reset is complete. Precautions for inflating tires: Always use a pressure gauge to check the tire pressure to avoid overinflation, which could cause the tire to burst. After stopping the vehicle, wait for the tires to cool down before inflating, as driving increases tire temperature, affecting the pressure. Check the valve stem. If the valve stem and valve core are not properly aligned, have protrusions, depressions, or other defects, it may be difficult to inflate or measure the pressure. Ensure cleanliness when inflating. The air pumped into the tire should not contain moisture or oil, as this can deteriorate and damage the inner rubber of the tire. Do not exceed the standard pressure excessively and then deflate, nor overinflate after a long period without inflation. Exceeding the standard pressure too much can overstretch the tire cords, reducing their strength and affecting the tire's lifespan.

What is the secret to parallel parking with a 30cm gap?

Sit in the car and adjust the seat and mirrors, then remember how wide the 30cm gap appears in the right rearview mirror. Use a fixed reference point on the car to align with the edge line—this could be a wiper node, a hood reinforcement rib, or a specific point on the dashboard.
