Vehicle vibrates while accelerating and stops when you take your leg off the pedal or accelerate more
I have a Toyota Highlander 2008 model. It vibrates when accelerating between 40-60kmph but stops when you accelerate more (over 60kmph) or take your leg off the pedal immediately you feel the vibration. The vibration becomes on and off as you travel at different speed but always for a very short while and it stops vibrating. I feel the vibration under the car like you just travelled on not so smooth road and it reflects on the whole body of the vehicle.
My car has 115000 miles.
My car has an automatic transmission.
Experienced mechanics share their insights in answering this question :
I suspect you have a problem in a CV joint, or if you have the all wheel drive version; in a drive shaft. The joints that enable the shafts to move around can wear out and when they do, they can produce a vibration at "resonate" speeds. There might be a vibration at 40 MPH that smooths out at 50 and then returns at 60. Or any other odd sounding pattern. You can have that conveniently checked out by contacting Your Mechanic. They can send a technician to your home or office who can check out your Toyota’s vibration and give you a more exact idea of what is the problem and what it will take to fix it.
How to Identify and Fix Common car Problems ?
Our sources include academic articles, blog posts, and personal essays from experienced mechanics :
The most common reason is that the engine is misfiring. When the engine misfires, it doesn`t run as smoothly as it should and can cause the car to shake. Another possible reason is that the spark plugs or ignition coils are dirty or damaged. This can also cause the engine to misfire and shake.
Tire issues: The most frequent causes of a vehicle shaking while driving stem from tire issues. Tires begin to behave differently when worn or out of balance. Tire replacement, realignment, and rebalancing are common solutions.
The Spark Plugs are Dirty or Worn
If your car`s spark plugs are worn or dirty, you will notice shaking during stopping and with acceleration. Remove the spark plugs and clean or replace them to correct this issue.
The most likely cause of the shuddering most often happens in the vicinity of your car`s rims and tires. They plant your car to the road, and if anything is broken, will feel it. On a serious note, it may be a broken transmission mount or a broken caliper.
Your vehicle`s engine and transmission send power to a differential and on to the wheels through a driveshaft. It rotates to transmit that power and torque, so a bend can cause major vibrations as you accelerate.
The most prevalent cause of vibration is problems with your wheels or tires. The potential problems include improper wheel and tire balance, uneven tire wear, separated tire tread, out of round tires, damaged wheels and even loose lug nuts.
The harder you brake, the more fluid pressure builds in the calipers, and the more pressure is applied to the brake pads and rotors. If the caliper or caliper pistons become stuck, it is unable to properly squeeze the brake pads against the rotors, which may cause you to feel some vibrations when you hit the brakes.
You may have a problem with the motor. The most common reason for shaking while idling can be loose engine mounts. Mounts are the links between the motor and vehicle — they keep the motor safely attached while dampening vibrations produced by your motor. When those connections wear out, you`ll feel the vibrations.
Low automatic transmission fluid can cause shaking. If the shaking is accompanied by the check engine light, it`s time to visit a mechanic. Drivers of manual cars might discover their clutch master cylinder is the source of the shaking.
Typically it`s from a damaged inner CV joint. These are located on the end of each axle. They both have an inner and outer joint that could be damaged and shake when you press the gas pedal. Another cause could be a broken motor mount.
Improperly functioning spark plugs cause an uneven burn of fuel in the engine, resulting in fluctuating RPMs and a louder noise. You might also experience increased vibrations of your vehicle while sitting idle or while traveling at low speeds. These vibrations originate from the engine and can shake the entire car.
As the cv joint wears down, it becomes less able to absorb shock and vibrations. This can cause the knocking sound, as well as other problems like a vibration when you`re driving. If you`re experiencing any of these symptoms, it`s important to get your cv axle shaft replaced as soon as possible.
Shaking or vibrating may be caused by many different things such as faulty spark plugs, poor fuel pressure or misfires. Other things such as a faulty idle air control valve may cause the engine idle to drop below the normal idling RPM which may also cause the motor to shake or vibrate more than normal.

There are several explanations for car shaking when braking: One of your tires could be badly “out of round” A wheel could be unbalanced having lost its counterweight. Your car`s front-end alignment could be way out of whack.

Is there vibrations and humming that gets louder when speed is increased then stops when vehicle stops a wheel bearing problem
ANSWER : From what you describe it is the front wheel bearings in the front hubs that need replaced. You should also check the tires for uneven wear and need for tire rotation or alignment issues causing uneven tire wear.
There is a shudder on take off and vibration while accelerating – 2013 Ford Focus
ANSWER : Hello there. Many possible faults can cause your 2013 Ford Focus to vibrate upon acceleration. From your description, it sounds like you are describing an engine misfire. Misfires can be caused by many issues, but the most common are spark plugs, coil, fuel pump, fuel injectors, MAF sensor, vacuum leaks, or a wiring harness fault.
A qualified technician, such as one from YourMechanic, will be able to diagnose your misfiring condition and make any repairs to get your vehicle running normally again.
ABS brakes lock up
ANSWER : It sounds like the traction control system and the ABS system may have been activated as a result of the bumpy road you were driving on. Your car is equipped with wheel speed sensors at each of the four wheels which monitor wheel speed while relaying this information constantly to the ABS and traction control system which are controlled by the car’s ECU. When the ECU senses an abnormal speed given specific conditions, it engages the ABS or traction control as needed to control the vehicle properly and safely. Occasionally, these sensors can fail or become faulty working intermittently sending inaccurate signals to the ECU. When this happens, you may experience the symptoms you have described. The ABS or traction control system may be inadvertently activated by these false or inaccurate signals. I would suggest having a professional from Your Mechanic come to your home to diagnose your ABS and traction control system.
When accelerating after a complete stop, turning corners, coming to a complete stop or randomly when Parked a very odd vibrating
ANSWER : Hello, thank you for writing in. The vehicle may be suffering from several different issues. In this type of situation you want to start with the least complicated option, and work your way up. Start by making sure your tires are properly inflated, and have them balanced. Your brakes may be playing a role, and you will want to start by cleaning them off with some brake cleaner, and make sure nothing is stuck between the pad and the rotor. You can then raise the vehicle and manipulate the wheel looking for excess play, damaged axles and joints, and damaged wheel bearings. From there you may need to look into the wheel assembly itself and make sure there is nothing mechanically wrong, dirty, or damaged. For more help diagnosing or resolving the vibration issue, contact our service department to schedule an appointment.
Slight delay when stepping on accelerator pedal
ANSWER : Hello. This delay is common in what is known as drive by wire engines. This means that the throttle is controlled by sensors and an electric motor. Most of the time when there is a delay that is this serious, it is caused by a programming issue or by the throttle body failing or being dirty. I usually start by checking the throttle body and cleaning it if it is dirty. If cleaning it does not help, I reprogram the engine computer. If the problem persists after that, then the throttle body usually needs to be replaced. If you need to have this looked at, consider YourMechanic, as a certified mechanic can come to your home or office to diagnose your acceleration concern.
I have 97 nissan altima, It stalls when I stop at stop lights and idle, the RPM vibrates and falls down and the lights come on, it
ANSWER : Hi there. Usually when you have a problem like this, it is caused by fuel system components that are clogged with excessive carbon build-up or deposits. This creates a restriction in the efficient flow of fuel and can cause the vehicle to stall. It’s also possible that emissions system components like EGR valve, mass air flow sensors or O2 sensors are faulty. I would recommend having a professional mechanic come to your location and complete a car starts the dies inspection, so they can pinpoint the source of your issues and recommend the right repairs.
Engine runs, but car doesn’t accelerate?
ANSWER : Knowing the results of the computer diagnosis as well as the part that was replaced can be helpful in assisting you with your Pontiac G3. It is possible the part that was replaced is defective and may need to be replaced. Based on what you described with your vehicle, it appears that you may be experiencing transmission issues.
The engine should never be revved up to six to seven thousand RPMs when the vehicle is not moving, as this can cause damage to the vehicle’s components. Because the information provided is a little unclear, it is hard to determine if you are having concerns with your transmission or if the problem lies with the engine itself.
If you don’t trust going back to the same mechanic that worked on your car originally, get yourself a second opinion and enlist the help of one of our certified mechanics who can diagnose why the Check Engine Light is on as well as determine why your Pontiac is not accelerating. They will also be able to assist you with the repairs needed to get your G3 up and running again.
