If your car shakes when accelerating, possible causes include an engine misfire, worn CV axle, damaged driveshaft, failing engine mount, transmission shudder, or a tire and wheel problem. The most useful clue is when the vibration happens. Shaking only when you press the accelerator can point toward a different problem than vibration at a steady highway speed or while braking. Here’s how to recognize the symptoms, understand the likely causes, and know when your vehicle needs professional attention.
A vehicle may shake during acceleration when an engine is running unevenly, a drivetrain component vibrates under load, or a tire, wheel, or suspension component has a problem. The cause depends on whether you feel the vibration in the steering wheel, seat, floor, or entire vehicle.
Pay attention to how the shaking changes when you release the gas pedal, maintain a steady speed, brake, or stop. These details can help a technician determine which systems to inspect.
| When the Shaking Happens | Possible Causes |
|---|---|
| Mostly when pressing the accelerator | CV axle, driveshaft, engine or transmission mount, misfire, or drivetrain concern |
| At a steady highway speed | Tire or wheel imbalance, tire damage, bent wheel, or related rotating component |
| When accelerating uphill or towing | Engine misfire under load, drivetrain shudder, or transmission concern |
| While stopped and idling | Engine misfire, rough idle, or worn engine mount |
| Mainly when braking | Brake rotor variation, brake hardware, or suspension-related concern |
| While turning and accelerating | CV joint, axle, or other steering and drivetrain component |
These patterns help narrow the possibilities but cannot confirm the problem on their own. A proper inspection is needed before replacing parts.
An engine misfire occurs when one or more cylinders fail to produce power as intended. Because the engine is no longer running smoothly, you may feel jerking, hesitation, or shaking, especially when accelerating or climbing a hill.
Possible causes include:
A misfire may also cause reduced power, a rough idle, increased fuel consumption, or a check engine light.
Important: If the check engine light is flashing, the vehicle may have an active malfunction capable of damaging the emissions system. Reduce engine load and follow the owner’s manual. If the vehicle is shaking severely or running poorly, pull over safely and arrange assistance rather than continuing to drive.
A worn constant-velocity (CV) axle or joint can cause shuddering when engine power is transferred to the wheels. This is especially relevant on front-wheel-drive and many all-wheel-drive vehicles.
Common clues include:
Not every acceleration vibration is caused by a CV axle. Tire imbalance, mounts, intermediate shaft bearings, and other drivetrain problems can feel similar. A technician can inspect the joints and related components to identify the actual fault.
Rear-wheel-drive and four-wheel-drive vehicles use driveshafts and related joints to transmit power between drivetrain components. A worn universal joint, damaged driveshaft, or related problem may create vibration, clunking, or unusual noise under load.
This can be particularly noticeable in trucks and SUVs, including Chevrolet Silverado and Colorado models, although the exact driveline configuration varies.
Possible symptoms include vibration during acceleration, clunks when changing between acceleration and deceleration, or shaking that becomes more noticeable at certain road speeds.
A severely worn or damaged driveshaft component can create a significant safety concern. Have persistent or worsening drivetrain vibration inspected promptly.
Engine and transmission mounts support the powertrain and help isolate normal engine movement from the vehicle cabin. When a mount deteriorates or breaks, more vibration may be transmitted into the body.
Symptoms can include:
Engine mounts do not explain every rough-idle or acceleration problem. A misfiring engine can create similar symptoms, so both engine performance and mount condition may need inspection.
Some automatic transmission problems produce a shudder or repeated vibration during light acceleration, gear changes, or torque converter clutch engagement. The sensation may resemble driving over a series of small bumps.
Other symptoms may include delayed engagement, slipping, harsh shifts, unusual noises, or a transmission warning message.
However, a transmission-like shudder is not proof that the transmission itself has failed. Engine misfires, driveline components, and all-wheel-drive systems can create similar sensations.
A technician may need to reproduce the symptom, evaluate operating conditions, and use diagnostic equipment before deciding whether transmission service or repair is necessary.
For related maintenance information, see our guide to checking transmission fluid.
Unbalanced wheels, damaged tires, bent rims, and uneven tire wear can create vibrations that increase with vehicle speed. These problems are often noticeable even when you’re not accelerating.
Common issues include:
Shaking felt primarily through the steering wheel can sometimes point toward front wheel or steering-related components, while vibration through the seat or floor may suggest a different location. These aren’t absolute rules.
If a tire has a bulge, visible structural damage, or a suspected separation, do not continue driving on it. Arrange inspection and replacement as appropriate.
Visit our Chevrolet tire center for tire service information.
Worn ball joints, control arm bushings, steering components, or wheel bearings can affect how a vehicle tracks and responds to road conditions. Depending on the fault, drivers may notice shaking, clunks, looseness, or uneven tire wear.
A wheel alignment problem can contribute to tire wear and handling concerns, but alignment alone is not usually the first explanation for a vehicle that shakes only when pressing the accelerator.
If the vehicle pulls strongly, feels unstable, or develops unusual steering behavior, have the steering and suspension system inspected before continued driving.
Shaking that becomes pronounced under acceleration and decreases when you release the gas may indicate a component that reacts to drivetrain load. Possibilities include a worn CV joint, driveshaft, engine mount, transmission component, or engine misfire under load.
The key distinction is whether the shaking follows engine load or primarily follows vehicle speed.
If the vibration disappears when you lift off the accelerator at the same road speed, that is valuable diagnostic information. Tell the service advisor exactly when it happens, how fast you’re traveling, and whether you’re going uphill or towing.
Shaking as you begin moving can result from engine misfires, worn mounts, axle or driveshaft problems, or certain transmission engagement concerns.
If the vehicle shakes while stopped in Drive but smooths out in Park or Neutral, engine mounts or engine performance may deserve closer inspection. If the vehicle feels smooth at idle but begins shuddering as the wheels turn, the drivetrain may be involved.
These patterns are not conclusive, and symptoms can overlap. Avoid attempting aggressive acceleration tests yourself if the vehicle is shaking severely.
Steering wheel vibration can be associated with tire and wheel issues, steering or suspension components, and some drivetrain faults. The pattern provides useful clues.
Do not assume a wheel balancing service will resolve every steering wheel shake. Persistent vibration should be properly diagnosed.
Accelerating uphill places more load on the engine and drivetrain. A problem that is barely noticeable on level roads may become more obvious during a climb.
Engine misfires, ignition or fuel-delivery problems, transmission shudder, or worn drivetrain components can all become more noticeable under load.
For drivers towing a camper or trailer with a Chevrolet truck or SUV, pay attention to whether the vibration also appears when carrying heavy loads. Stop driving if it becomes severe, the engine loses power, or a warning indicates a condition requiring immediate attention.
A vibration that happens mainly when you apply the brakes is more likely to involve the braking system than a typical acceleration-only problem.
Variations in brake rotor thickness, brake component problems, or certain suspension issues can contribute to vibration during braking.
If shaking occurs during both acceleration and braking, more than one system may need inspection.
Read about Chevrolet brake service if you notice brake pedal pulsation, grinding, or other braking concerns.
Not always. Mild vibration may be caused by a relatively straightforward problem, but severe or sudden shaking can indicate a tire, steering, engine, or drivetrain fault that makes driving unsafe.
Stop safely and arrange assistance if you notice:
Do not deliberately recreate severe vibration at highway speed. If you’re unsure the vehicle is safe to operate, have it transported for inspection.
A professional diagnosis begins by identifying the conditions that produce the shake. Different symptoms point toward different systems, and replacing parts before confirming the cause can create unnecessary expense.
The exact diagnostic process depends on the vehicle. Modern Chevrolet models may require specialized diagnostic equipment or manufacturer service procedures.
Nebraska road conditions can contribute to certain vibration problems, particularly after a pothole impact or when tires and suspension components experience damage.

A car may shake during acceleration because of an engine misfire, worn CV axle, damaged driveshaft, failing engine mount, transmission shudder, or a tire and wheel problem. The cause depends on when and where the vibration occurs. Professional inspection is needed to identify the specific fault.
Vibration that increases under throttle and decreases when you release the accelerator may involve a component affected by engine or drivetrain load. Possible causes include CV joints, driveshafts, engine mounts, transmission components, or an engine misfire. The symptom helps narrow the diagnosis but does not confirm one cause.
Yes. Worn or faulty spark plugs can cause an engine misfire, which may produce shaking, hesitation, or reduced power during acceleration. Ignition coils, fuel-delivery problems, and other engine faults can cause similar symptoms. A flashing check engine light with severe shaking requires urgent attention.
Yes. A worn CV joint or axle can cause shuddering when power is transferred to the wheels, sometimes becoming less noticeable when you release the accelerator. Clicking during turns or grease leaking from a damaged CV boot can be additional clues.
Steering wheel shaking may be related to tire or wheel imbalance, damaged tires, steering or suspension problems, or certain front drivetrain components. Vibration at a steady highway speed often suggests a different cause than shaking that occurs mainly when applying throttle.
Yes. Some transmission or torque converter problems can produce shuddering during acceleration or gear changes. However, engine misfires, drivetrain faults, and other problems can feel similar. The transmission should be diagnosed before assuming it needs repair or replacement.
It depends on the cause and severity. Stop safely and arrange assistance if the shaking is severe or worsening, a tire appears damaged, steering becomes unpredictable, the engine loses significant power, or the check engine light flashes with rough operation. Persistent vibration should be inspected promptly.
