Questions and Answers
reader:Will the automatic transmission turn off? I was driving on the road one day and it suddenly died of fire. I quickly stepped on the brakes and restarted the ignition, but the car would not start. What should I do if I encounter this problem?
answer:Although the automatic transmission car does not have a clutch, it is still possible to accidentally stop the engine in the middle due to mechanical failure. When you find that the battery light is on, it will turn off the engine. At this time, don't mess with the steering wheel and step on the brakes many times, because there are generally only two opportunities to brake after the engine is turned off. Then, quickly push the shift lever into neutral, turn the ignition switch to the start position, and after the restart is successful, quickly pull the shift lever to the D lever to drive normally. If the engine still fails to start after several attempts, it indicates that the fault is serious, and it should be stopped for maintenance. To apply this method, you must be familiar with the operation of the vehicle. If the force is too large, pushing the shift lever directly into the reverse gear will cause great damage to the transmission.
NO.1 The engine cannot be started
Case:Xiao Liu was about to drive home after get off work, but he found that no matter how he started the engine, the engine would not catch fire, but he was so anxious, what was the reason?
Whether distributors, spark plugs, high-voltage lines, etc. are affected by moisture due to rain or car washing. Expert interpretation: Recently, it has been raining frequently, and some vehicle parts are prone to rain. If so, these damp parts will affect the start of the vehicle. Owners need to think carefully Think about whether you have let water in the engine compartment of your car.
Approach:Turn off the vehicle first, let the damp parts dry before starting the car.
Expert advice:The engine compartment is usually closed tightly, and try not to open it in the rain. Check whether the battery voltage is enough for expert interpretation: listen carefully to see if the engine makes a babbling sound, if so, it means your battery is dead. The best way to prevent the battery from suddenly running out of power is to pay more attention to the "SOS signal" issued by your car. This signal has the following manifestations: first, the starter does not rotate or rotates weakly, so that the starter cannot be started; second, the headlights are darker than usual; third, the volume of the horn is low or even silent.
Approach:Use the "Cross River Dragon" connecting cable to connect to other vehicle batteries for temporary power supply in order to start the vehicle.
Expert advice:Avoid turning on the lights or listening to the radio for a long time when the engine is turned off; if you park for a long time, you should also turn off the power of unnecessary electrical equipment (lights inside and outside the car, audio, navigation, etc.).
NO.2 Steering wheel trembles when the vehicle is driving
Case:Recently, Mr. Zhou drove his car to the countryside with his family. When he came back, he always felt that the steering wheel was shaking when the vehicle was driving. For no reason, he stopped by the roadside and waited for someone from the 4S shop to come and help him.
Whether there are debris, stones and other debris stuck on the tires of the vehicle
Expert interpretation:When playing in the countryside, it is easy to pass through some muddy roads, and the tires are easy to stick to debris such as mud and stones, which will affect the steering wheel, and the debris is not good for high-speed driving, which is easy to cause tire blowout.
Approach:Remove stones from tire gaps and debris stuck to wheels.
Expert advice:Always pay attention to cleaning the tires.
The tire is deformed by the impact or the wheel balance weight falls off
Expert interpretation:If the tires are clean and the problem persists, you need to double-check the tires for any bumps.
Approach:In order to avoid potential safety hazards, the deformed tires should be replaced in time, and the nearest auto repair shop should be found to install the balance weight.
Expert advice:Don't be careless about this problem. Some bumps are not formed after the impact, which is not obvious, but a careful inspection can still find the problem.
No four-wheel alignment expert interpretation after tire replacement: If the vehicle does not have any of the above two problems, there is another possibility that four-wheel alignment is not performed after tire replacement: You should seek a professional auto repair shop for four-wheel alignment in time to avoid Security risks.
Expert advice:When changing tires, it is best to perform four-wheel alignment at the same time.
NO.3 The old electric windows automatically drop
Case:Xiaomei's car is an imported luxury car, and the windows are all designed to lift with one button. However, during the recent use, she found that the power window on the main driver's side would suddenly drop automatically when it was raised to the top. The next time I closed the window, I was very careful and laborious.
Expert interpretation of sensor-activated anti-pinch function: Generally, high-end cars will install an anti-pinch function in the design of power windows to avoid personal injury caused by accidental operation. During the use of the vehicle, if there are some objects embedded in the top frame of the door, when the window rises to this position, the sensor will activate the anti-pinch function to lower the window.
Approach:Check to see if there is any foreign object affecting the window lift and clean it up.
Expert advice:If it only occurs during high-speed driving, it may be the cause of the voltage, which needs to be adjusted at the 4S shop.
NO.4 The back door is not closed tightly
Case:Mr. Xu recently discovered that when the rear door of his car was closed, the lock on the door could not fasten the hook on the body, resulting in the rear door not closing tightly. It takes a hard push on the door or multiple door closing actions to close the door.
Excessive friction or body deformation expert interpretation: It is necessary to observe whether the clearance fit is serious. If it is only due to design or friction problems, just apply some lubricating oil, but if it is serious, you need to pay attention to whether the body is deformed.
Approach:Adjust the position of the door lock module and the position of the body hook to make the fit better; apply grease to the lock and hook positions to enhance lubrication.
Expert advice:If it is a new car, the door is not closed tightly because most of the components do not cooperate well during installation. If there is a serious gap and fit problem, you can directly go to the 4S shop to make a claim and request to adjust the gap.
