Has the problem of Koleos vehicle shake been solved?

Judging from the information of netizens on major automobile forums, this problem has not yet been solved.

The following is Dongfeng Renault's official explanation of the jitter problem:

When the vehicle is coasting at low speed, in order to save fuel consumption, the engine does not make power output at this time, and the torque converter connected between the gearbox and the engine is still in a locked state, and the engine and the gearbox are equivalent to direct hard connection. At this time, the whole vehicle is dragging the engine forward. Once the throttle is lightly refueled, the engine provides power output, the vehicle changes from a coasting state to an accelerated state, and the attitude of the engine also changes from passive drag to active drive.

In this process of transformation, a slight sense of impact will be exhibited due to the action of inertia. At the same time, due to the gear clearance in the transmission system (due to the thermal expansion and contraction characteristics of the metal and the machining accuracy, there will be gear backlash in the design), the pause will be accompanied by a slight gear meshing sound, and the pause and abnormal noise of customer feedback are within the normal range in the performance evaluation of the Renault-Nissan Alliance.

As far as the official call is a normal phenomenon, this problem should not be solved until the vehicle is replaced with an engine. However, there are also many netizens who say that the probability of jitter in Koleo's model will be significantly less than that of the model, if you are interested in Koleo and are more concerned about the jitter problem, it is recommended that you buy the model, or wait and see for a while to see if the problem can be solved when the model is changed or replaced.

If you haven't heard of this problem, this may be an isolated case, but you shouldn't be particularly worried about it anyway.

The engine is noisy.

It's possible to switch to fake oil.

Or you changed the oil grade too low.

Buy a better oil change and try it.

SN-level.

Summary. Kore's engine feels a little shaky when accelerating arrogantly, mainly due to the inadequacy of the car's engine exhaust system. The exhaust system of the car is composed of exhaust pipes, mufflers, valves, combustion chambers, etc., and the function of the exhaust system is to remove the smoke in the combustion chamber and eliminate the noise emitted by the engine.

If Kore's arrogant exhaust system is not sound, the engine will have a small tingling sensation when accelerating, which will affect the car's driving stability and engine performance.

Glad to have questions for you; The engine felt a little tingling when Kore accelerated arrogantly, which was most likely caused by the vibrations of the engine. Koleo's engine is turbocharged with turbocharging technology, which increases the vibration of the engine when it accelerates, resulting in a sense of shake in the engine. This is normal and there is no need to worry about the liquid bridge.

Brothers! Koleo's engine is not turbocharged, it is naturally aspirated!!

It's a Nissan engine, the same platform as the X-Trail, the same engine and gearbox!

Okay kiss me question.

Kore's engine engine design feels a little shaky when accelerating arrogantly, mainly due to the inadequacy of the car's engine exhaust system. The exhaust system of the car is composed of exhaust pipes, mufflers, valves, key combustion chambers, etc., and the function of the exhaust system is to remove the smoke in the combustion chamber and eliminate the noise emitted by the engine. If Kore's arrogant exhaust system is not sound, the engine will have a small tingling sensation when accelerating, which will affect the car's driving stability and engine performance.

So what about the exhaust system that we need to overhaul?

To overhaul the exhaust system, it is necessary to check the pipes, exhaust ports, control devices of the exhaust system, and regulating devices of the exhaust system in the exhaust system. It is also necessary to check the various valves, switches, pipelines, joints and other components involved in the exhaust system, as well as the tightness and tightness of the exhaust system.

The Renault Koleos shook around 60 yards, and the speed was normal.

Hello, the car can not add the throttle to the bureau, and there is a feeling of frustration when speeding up, it is recommended to do the following inspections: first, this is more common is the aging of the vehicle spark plug or the ignition coil damage caused by this situation, this can go to the repair shop to disassemble the spark plug, check the size of the spark plug clearance, if the gap is too large, or the wear is more serious, generally replace the spark plug can solve the problem. The inspection of the ignition coil needs to use the computer to read the specific fault code, if the corresponding cylinder has a misfire, it is generally the problem of the ignition noise coil.

Second, the engine has too much carbon deposit, resulting in weak speed, and it is recommended to clean the engine carbon deposit, especially the throttle inlet and cylinder carbon deposit. The carbon deposits in the cylinder are mainly the carbon deposits at the piston position and the valve base position, and then rematch the throttle! Third, the fault caused by the failure of the oil circuit, this needs to detect whether the fuel supply pressure of the gasoline pump is normal, if the oil supply pressure is unstable, it is necessary to replace the new gasoline pump in time.

Hello, dear, the vehicle can not speed up and jog up this fault performance, it is recommended to check the following aspects of the fault causes: first, the vehicle engine carbon deposition caused by the jitter or speed up weakness, in this case, it is recommended to clean the throttle and air intake tract carbon deposition, and then check the cylinder ridge hand carbon deposition, valve base carbon deposition is serious. Second, the ignition of the engine is a failure of the Ashino system, which is generally caused by the ignition coil or the aging of the spark plug, and the damaged ignition coil can be replaced or the spark plug can be replaced.

Third, if the engine fuel system fails, the oil circuit is too dirty, or the fuel quality is too poor to accompany the hand, it is recommended to clean the oil circuit, and then add some high-grade gasoline, or fuel treasure. In the last case, it is considered that it is caused by the problem of the vehicle's gearbox, the internal friction plate of the gearbox is worn, or the solenoid valve body has been damaged, and the upshift is not timely or the acceleration is weak. The gearbox needs to be checked.

Hello, I wish you a happy life, if you have any questions, you can consult at any time, I will reply to you as soon as possible.

The cause of body shake when driving at high speeds.

There are several reasons for the unstable driving, head swinging, and steering wheel shaking when the car is driving at high speeds

1. The positioning angle of the front wheel is inaccurate, and the toe is too large.

2. The air pressure of the front tire is too low or the tire is unbalanced due to repair and other reasons.

3. The front spokes are deformed or the number of tire bolts is different.

4. The installation of transmission system parts is loose.

5. The transmission shaft is bent, the power is unbalanced, and the front axle is deformed.

6. The shock absorber is faulty.

High-speed car oscillating steering wheel shake solution.

First, with the increase of vehicle speed, the oscillation becomes stronger.

The second is oscillation at a certain higher speed, which causes the steering wheel to shake.

The drive axle can be erected first, the front wheel is plugged with safety plug blocks, the engine is started and gradually shifted into the high-speed gear, so that the drive wheel reaches the final test oscillation speed.

If both the body and steering wheel shake at this time, it is caused by the drivetrain.

Because the front axle of the front wheel is in a stationary state at this time, if the final test oscillation speed is reached, the car does not shake, then the reason for the oscillation is that the front axle part of the car is faulty;

Check whether the positioning angle and toe of the front wheel meet the requirements, and adjust if it is out of alignment;

Set up the front axle and test the wheels to check the dynamic balance of the wheels and whether the tires are too deformed.

If necessary, a good wheel can be replaced for a comparative test;

Check whether the front axle and frame are deformed, check whether the transmission shaft is bent, and make the dynamic balance of the transmission shaft when possible.

The situation you mentioned may mean that the vehicle has the following three conditions:

1.The engine has a lot of carbon deposits.

The most common cause of car shake is a dirty throttle or excessive carbon build-up in the fuel injector. When the carbon deposition inside the engine is excessive, the gasoline sprayed by the cold start fuel injector will be absorbed by the carbon deposition in large quantities, resulting in the mixture of cold start being too thin, making it difficult to start, in this case, only when the gasoline absorbed by carbon deposition is saturated, it is easy to get on the car, and the gasoline adsorbed on the carbon deposition after the car will be sucked into the cylinder by the vacuum suction of the engine for combustion, and the mixture becomes thick, and the combustible mixture of the engine is dilute and thick, causing idle shaking after cold start. The lower the temperature, the greater the amount of oil required for the cold start, and the more carbon deposits will affect the smooth cold start.

Solution: Clean the oil circuit and check whether the idle motor has carbon deposits and should be cleaned.

2.Problems with the ignition system.

Check the working condition of the spark plug, high-voltage wire and ignition coil, the ignition system is not working well, and the spark plug tripping condition is not good, which will also lead to this kind of failure.

Solution: Check whether the spark plug has too much carbon deposit, and replace the spark plug.

3.The oil pressure is unstable.

If you have cleaned the engine carbon deposit, washed the throttle, changed the oil pad and spark plug, etc., and still found that the body shakes when idling, it is recommended that you go to the 4S shop to check whether the fuel supply pressure and intake pressure sensor are normal, if the oil pump supply pressure is abnormal or the intake pressure sensor value is wrong and the work is not good, the body shake will be triggered.

Solution: Check the oil pressure and replace the parts if necessary.

4. Aging of engine parts.

Car jitter is also related to the aging of the engine feet (also known as claw pads). The engine foot is actually the suspension system of the engine, and the engine foot is responsible for absorbing the subtle shake of the engine when it is running, and if there is a problem with the engine foot, these vibrations will be transmitted to the steering wheel and cab, causing shaking when idling.

Workaround: Replace the parts.

Engine failure lights are usually lit for the following reasons:

1. The combustion state is not good.

Poor engine combustion condition is the main reason why the engine failure light is on.

2. Engine knocking.

There are usually three scenarios:

The first case: the car has no power to hold the hall;

The second case: the car is weak and the engine noise is too loud;

The third case: there is an obvious knocking sound.

In the first case, some engine fault lights will be on, some will not, and in the second and third rental and burial situations, the engine fault lights will inevitably turn on.

3. The internal reason why the engine failure light is on.

1) The fuel quality is not good.

2) The inside of the engine cylinder is not clean and there is carbon deposit.

The engine is noisy.

It's possible to switch to fake oil.

Or maybe you change to a bright rock wide and fierce engine oil grade is too low.

Buy a little rough bridge oil change.

Try it. SN-level.

Clean the throttle and idle motor.
