Experienced mechanics share their insights in answering this question :

Hi there! There are several reasons why your TL can act this way.

First off, if this behavior is predominantly after the car has been sitting overnight or longer, it can be the result of "flat-spotting" – the low profile tires, with very stiff sidewall, develop "flat spots" where the tire sits on the pavement. This is overcome with 5-10 miles of highway driving, and the tire heat up a bit, and air pressure in the tire makes them round again.

The second possibility is out-of-balance tire/wheel combinations. Your tire shop can check the balance for you, and correct balance if necessary.

The third possibility is an axle with bad CV joints. If the CV joints are worn, they essentially "wobble", and this vibration is transmitted into the structure of the vehicle – which you could feel both with the steering wheel, and "seat-of-the-pants".

To avoid any unnecessary repairs, I would recommend having the shaking symptom diagnosed by a mobile, professional mechanic, such as one from YourMechanic, to diagnose this problem, get an accurate assessment of damage and cost estimate for repairs.

Common reasons for this to happen:

Loose connections at the positive and negative battery terminals. Very dirty or clogged air filters can also cause your engine to underperform. Loose timing belts are another likely cause. A mechanic will check these and replace them if they appear loose and worn.

The most common reason for a car to shake is related to tires. If the tires are out of balance then the steering wheel can shake. This shaking starts at around 50-55 miles per hour (mph). It gets worse around 60 mph but starts to get better at high speeds.

Some Common Causes of Vibration in Acura Include

Tire imbalance may go unnoticed at lower speeds, but at 60 MPH and higher your vehicle may experience violent shakes. Thankfully, checking and adjusting tire balance and alignment is usually an easy fix.

Car/Steering Wheel Shakes Between 50-60 MPH – If you`re feeling a strong vibrating feeling in your steering wheel as you approach highway speeds, then it`s likely that your tires are out of balance and need to be rotated or aligned.

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.

Your Tires Need to Be Balanced

Unbalanced tires result in your car shaking when braking. It may even create a shuddering sensation while driving. We recommend scheduling service with your dealership`s tire center to have your tires balanced.

Some simple warning signs that the transmission is having problems: Transmission is slow to respond when shifting. Grinding, shaking, vibrating.

Worn or dirty spark plugs can cause a petrol car`s engine to misfire in one or more cylinders, which can cause vibrations when the car is idling or at running speeds. The easiest solution is to replace your spark plugs and check the related wiring. Engine vibrations can also be due to the air and fuel systems.

Tire Problems

Tires are one of the most common causes of car vibrations. One of the possible issues are out-of-balance tires. Your problems may not be noticeable at slow speeds, but the shaking will intensify as you accelerate to 55-60 miles per hour. The steering wheel, or even the entire car, will start to vibrate.

If you find that your steering wheel shakes at high speeds or is shaking when you brake, you`re probably wondering what to do when your steering wheel shakes and what it means. Most of the time, a shaky steering wheel is caused by unbalanced or misaligned wheels.

Misaligned tyres can cause the car to vibrate when driving at high speeds, usually between 50 to 75 mph. Hitting a kerb or driving over a pothole can throw your wheels out of alignment which, in turn, can cause your vehicle to vibrate.

If you begin to feel persistent shaking in your car, it`s best that you get to the problem right away before continuing to drive. Continuing to drive with the shaking can result in further damaging parts, ruining your tires, and other costly problems that could be avoided by a quick trip to your mechanic.

Brake pads wear over time — there`s no avoiding it. And depending on how either the pads or rotor wears, you may feel vibrations. If your vehicle vibrates when you apply the brakes and is accompanied by an annoying squealing sound, it`s likely time to get your brake serviced at Tires Plus.

The Shaking is Your Brake Calipers Sticking

The fluid creates hydraulic pressure which forces the caliper to press the pads. If you feel the vibration only in the steering wheel, it could be the calipers sticking and failing to press the pads against the rotors.

If your steering wheel is quivering when you brake or shaking when you stop, something`s likely going haywire in your brake system. From worn brake pads to dry guide pins and warped rotors, there are a variety of common culprits.

Unbalanced or Damaged Wheels – Around 45 MPH, you may feel a vibration through the steering wheel. As you increase in speed, the vibration will intensify. In order to rotate properly, the wheels of a vehicle need to be balanced.

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.

Vibration While Driving. Because the CV Axle joints are located right next to the vehicle`s wheels, any damage to them can directly affect your driving. If you suddenly feel as though your vehicle is vibrating more than normal, it can mean that you have a damaged halfshaft.

Vibration risks come from many sources including hand-held power tools (such as grinders or road breakers) and hand-guided equipment (like pedestrian controlled floor saws).

To help confirm that the vehicle has an engine speed related vibration, with the vehicle stopped, put it into park or neutral and raise the engine speed to the RPM at which the vibration occurred to see if the vibration can be reproduced. If reproduced, diagnosis should begin with engine speed related components.

Vibration-induced white finger (VWF) is the most common condition among the operators of hand-held vibrating tools. The symptoms of VWF are aggravated when the hands are exposed to cold. Vibration can cause changes in tendons, muscles, bones and joints, and can affect the nervous system.

When the torque converter starts malfunctioning, you may feel shuddering and even slipping in overdrive. You usually notice your car shuddering because it feels like it`s vibrating. Your car will vibrate even when you`re not going very fast. The shuddering makes the car lag and is very noticeable.

Typically, when your transmission begins to fail you may start to notice some form of difficulty when changing gears. Occasionally you may hear or feel a clunk noise when you shift gear. Another sign of a rough shifting is difficulty in accelerating to the speed for the gear that it is in.

One of the most common engine mount symptoms is increased vibrations while using your vehicle. If you start your engine and notice that it is making more noise than usual and you can feel more vibrations than usual, this is a key sign of a worn engine mount that may need replacing.

When I start my car up it feels like it’s going to cut off it’s shakes the idle feels like it’s going to cut off it’s just shakes

ANSWER : Hello, thank you for writing in. There is a component on the vehicle known as the "idle air control valve", which is responsible for managing the idle speed when you are not on the throttle. It is also utilized when slowing down between letting off the gas and pressing the brake. If this valve is overly dirty, has an air leak, or has failed, you will experience similar issues. You may also need to look into the throttle itself, the intake air sensors, and the fuel pressure. Only further testing will tell exactly what system is having issues. For more help with diagnostics, contact our service department to schedule an appointment.

ANSWER : Hi there. There are many sources that cause vibration, and if a single component designed to dampen that fails, you’ll feel it. Motor mounts, transmission mounts, suspension bushings are just a few of the things that are designed to minimize vibration. However, damage to fuel system components like a mass air flow sensor can also cause this type of problem. The best way to narrow the causes down is to have a professional mobile mechanic come to your location and complete a car shakes and vibrates inspection.

My car will not start Intermittently. I purchased a new battery 2 weeks ago and yesterday the car wouldn’t start. Got a jump and

ANSWER : The issue you are having is probably due to an intermittent fault in the starter motor itself or a deficiency in the starter electrical circuit, for example a large voltage drop due to a poor ground or a high resistance connection. These issues can be readily diagnosed and resolved on a mobile basis if you request a hard starting diagnostic. If you request that diagnostic, the responding certified mechanic will get this resolved for you promptly. Based on Toyota’s Factory Service Manual, the battery should not be disconnected if the vehicle engine is running. The battery acts as a large resistive voltage sink and consequently taking the battery out of the circuit, while the alternator is still running, can create a voltage spike on the car’s electrical system which is not good for voltage sensitive components such as the engine computer. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

I was stopped on the freeway, started to go about 5 mph, the car jerked and stop without warning like the wheels locked up.

ANSWER : Hi, thanks for writing in. I’d be happy to try to help. It is hard to definitively diagnose what the issue is. At first it seems like a transmission issue. Automatic transmissions are rather complicated and can do strange things when they malfunction. If not an issue with the transmission, you could also have a clutch issue. Always start by checking the simple components first. Check your transmission fluid level. Make sure your transmission filter is clean and debris free. When you have the transmission pan off, you can look and see if there are any metal shavings at the bottom. There is often a small magnet at the bottom of the pan designed to gather any metal shavings for a quick diagnosis. This is a sign of more serious transmission problems. Unless you have experience with automatic transmissions, it is not recommended that major repairs be done at home. I suggest taking your car to a transmission specialist for help.

My car stutter starts, but only after driving it for a few minutes.

ANSWER : Hey there. This may also be caused by what is called the fuel pressure regulator. This is a unit that helps to maintain the fuel pressure at the proper level. When this is not working properly, the fuel pump may be pumping properly, but the fuel may not arrive at the fuel injectors at the proper psi. When this happens, this can cause a lean fuel condition which may cause the car to hesitate, misfire, or stall. If you would like to have an expert pinpoint the issue, a certified professional from YourMechanic can come to your car’s location to inspect the hard start problem and confirm which repairs are needed.

Vauxhall Astra CDTi 55 plate after driving the car for a while it will stop while i’m driving or not start up again after parking

ANSWER : There are many variables that come into play in a no-start situation, especially an intermittent one. Since you have already had some work done, we can rule those out. Since you are having to drive before the issue happens, I would suspect a module of some sort.

Modules are another term for computer. Much like your home computer, car computers don’t like heat, so once they become too hot, it stops working. Since your vehicle’s fuel and ignition systems are controlled by a module, it makes sense that it would turn off when the module overheats. Waiting a while allows it to cool off and work again.

If you need further assistance with your problem, I recommend having a certified mechanic from YourMechanic, come to your home or office to diagnose your car’s starting issue. From there, they will be able to make any of the needed repairs that your car needs.
