Common Causes of Shaking When Accelerating
If your INFINITI shakes when driving, it's more than just an annoyance. It could be a sign of a bigger issue. Several parts of your vehicle work together to ensure a smooth ride. When one of them fails, vibrations can happen. Below are the most common reasons why your INFINITI might shake when you accelerate. If you notice these signs, schedule an inspection at INFINITI of South Bay for a full diagnosis.
1. Engine Troubles: A Potential Culprit
Your engine plays a key role in smooth driving. If it struggles, your vehicle may shake when you press the gas.
Possible Causes:
- Misfiring Cylinders – If a spark plug fails, one or more cylinders won’t fire properly. This causes uneven power and shaking.
- Fuel System Issues – A clogged fuel injector can stop the right amount of fuel from reaching the engine. This leads to rough acceleration.
- Blocked Air Filter – Your engine needs air to burn fuel. A dirty air filter reduces airflow, causing your car to stutter and shake.
Warning Signs:
- Engine light turns on
- Loss of power when accelerating
- Jerking or shaking when you press the gas
Vehicles Affected:
- INFINITI QX80
- INFINITI QX60
If you notice these problems, don’t wait. Visit INFINITI of South Bay to get your engine checked before it gets worse.
2. Tire and Wheel Issues That Cause Vibrations
If your INFINITI shakes when pressing the pedal, the problem could start with your tires or wheels. These are the parts that connect your car to the road. When they have issues, you will feel it.
Common Tire and Wheel Problems That Cause Shaking
- Unbalanced Tires – If your tires are not balanced, they can cause vibrations that get worse as you drive faster.
- Misaligned Wheels – When your wheels are not in the right position, your car may shake or pull to one side.
- Worn-Out Tires – If your tire treads are too low, they won’t grip the road well, which can lead to shaking.
- Incorrect Tire Pressure – Too much or too little air in your tires can cause an uneven ride.
The Impact of Tire Problems on Smooth Driving
Each of these issues can make your INFINITI QX50 shake when you press the pedal. When tires or wheels are not working right, the car does not move as smoothly. Over time, these small shakes can cause bigger problems, such as:
- More wear on your tires and suspension
- A rougher and less comfortable drive
- Lower gas mileage
How to Prevent Tire and Wheel-Related Vibrations
Regular tire checks help keep your ride smooth. Here’s what you should do:
- Get tires balanced every time you rotate them.
- Check wheel alignment at least once a year or after hitting a pothole.
- Inspect tire tread depth often and replace tires when they wear down.
- Keep tire pressure at the recommended level to avoid uneven wear.
At INFINITI of South Bay, we can inspect your tires, fix alignment issues, and ensure your QX50 drives smoothly. If your INFINITI shakes when pressing the pedal, don’t wait—schedule an inspection today!
3. Driveshaft and Axle Problems
When your INFINITI QX60 shakes while you press the pedal, the issue may come from the driveshaft or axles. These parts help transfer power from the engine to the wheels. If they are bent or damaged, you may feel vibrations while driving.
Common Causes of Axle and Driveshaft Issues
Several problems can cause your INFINITI to shake when accelerating:
- Bent or damaged axles – Even a small bend can create strong vibrations at higher speeds.
- Worn-out CV joints – These joints help your wheels turn smoothly. If they fail, you may hear a clicking or popping noise.
- Failing driveshaft – If the driveshaft is loose or unbalanced, your vehicle may shake more as speed increases.
Signs of Axle or Driveshaft Damage
If you notice any of these signs, you may need repairs:
| Sign | Possible Cause |
| Car shakes when you speed up | Bent axle or bad CV joint |
| Clicking noise when turning | CV joint failure |
| Loud clunking when shifting | Loose driveshaft |
| Vibrations that get worse over time | Worn driveshaft or axle |
Why Fixing the Problem Matters
Ignoring these issues can make the shaking worse. Over time, a failing axle or driveshaft can damage other parts of your QX60. Getting an inspection at INFINITI of South Bay can help prevent bigger repairs. If your INFINITI is making noise when accelerating, bring it in for a full checkup.
4. Brake System Complications
If your INFINITI QX55 shakes when driving or stopping, the problem may come from the brake system. Brakes should slow your car smoothly. If they don’t, it could be due to worn or damaged parts.
How Brakes Cause Shaking
Several brake issues can lead to vibrations:
- Warped brake rotors – The rotors help stop your car. If they are uneven, you may feel a shake when braking.
- Worn-out brake pads – Brake pads press against the rotors to slow your car. If they wear unevenly, your car may vibrate.
- Stuck brake calipers – Calipers hold the brake pads in place. If they don’t release properly, you may feel shaking while driving.
Signs You Need Brake Service
Watch for these signs of brake trouble:
| Sign | Possible Cause |
| Shaking when braking | Warped rotors |
| Grinding or squeaking noise | Worn-out brake pads |
| Car pulls to one side | Uneven brake pad wear |
| Burning smell after driving | Stuck brake caliper |
Why Brake Maintenance Matters
A bad braking system can make your INFINITI shake when driving and increase stopping distance. This can be dangerous. If you notice any of these signs, visit INFINITI of South Bay for an inspection. A quick brake check can keep you safe and help avoid costly repairs.
5. Transmission and Mounting Issues
If your INFINITI QX80 shakes when pressing the pedal, the transmission or engine mounts could be the cause. These parts help keep your drive smooth. When they wear out, shaking and vibrations may start.
How Transmission Issues Cause Shaking
Your transmission moves power from the engine to the wheels. When it malfunctions, you may feel a shake when you speed up.
- Low or dirty transmission fluid – Thick or old fluid makes shifting rough. This can cause jerking or shaking.
- Worn-out gears – If gears slip, your car may shudder while moving.
- Fluid leaks – A leak can cause low pressure in the system, leading to vibrations.
How Engine and Transmission Mounts Affect Stability
Mounts hold the engine and transmission in place. They absorb vibrations so you don’t feel them inside the car.
| Problem | Effect on Driving |
| Worn-out mounts | More shaking when pressing the pedal |
| Loose mounts | Engine moves too much, causing jerks |
| Broken mounts | Strong vibrations when idling or accelerating |
Why Prompt Repairs Matter
Ignoring these issues can lead to costly repairs. If your INFINITI QX80 shakes when pressing the pedal, visit INFINITI of South Bay for a full checkup. Fixing the problem early can prevent further damage and keep your drive smooth.
How to Fix and Prevent the Shaking in Your INFINITI
If your INFINITI QX50 is making noise when accelerating or shaking when driving, it’s time to take action. Finding the cause early can help prevent bigger problems.
Steps to Diagnose and Address the Issue
Start with a simple check before seeking a repair.
- Inspect your tires – Look for uneven wear, low pressure, or damage.
- Check your brakes – Warped rotors or worn pads can cause vibrations.
- Listen for noises – Strange sounds while accelerating may point to an engine or transmission issue.
- Look for leaks – Fluid under your car could mean transmission or engine trouble.
- Test your drive – If shaking worsens at high speeds, your suspension or driveshaft may be the cause.
If these checks don’t solve the issue, visit INFINITI of South Bay for a professional inspection.
Routine Maintenance to Keep Your Ride Smooth
Preventing shaking and strange noises starts with regular maintenance.
| Service | Why It Matters | When to Do It |
| Tire Balancing & Rotation | Ensures even wear and smooth driving | Every 5,000-7,500 miles |
| Brake Inspections | Prevents vibrations from warped rotors | Every 10,000 miles |
| Engine Tune-ups | Keeps power smooth and responsive | Every 30,000 miles |
| Transmission Service | Stops slipping and rough shifting | Every 30,000-60,000 miles |
Following these steps reduces wear on key parts. If your INFINITI QX50 shakes or makes noise when accelerating, don’t wait. Bring it to INFINITI of South Bay for expert care.
