Rough Ride and Clunking Noise from Front Suspension on 2021 Encore GX

Vehicle: 2021 Buick Encore GX Select

Hi all,

I'm experiencing a really rough ride in my 2021 Buick Encore GX Select, especially over bumps and uneven roads. It feels like every little imperfection is amplified, and the car just doesn't feel as smooth as it used to. I've also started hearing a distinct clunking noise coming from the front suspension, particularly when going over speed bumps or potholes.

The car only has about 35,000 miles on it, which seems a bit early for major suspension issues. I've checked the tire pressure, and it's all good. Could this be a strut issue, or something else entirely? Any advice on what to look for or common problems with these models?

ClearTheCode admin answer:

A rough ride combined with clunking noises from the front suspension on a relatively new vehicle like your 2021 Buick Encore GX can be concerning. Here are the most likely culprits and steps for diagnosis:

  1. Worn or Leaking Struts/Shocks: Even at 35,000 miles, a strut could fail prematurely, especially if you frequently drive on rough roads. A leaking strut will lose its dampening ability, leading to a bouncy or harsh ride and potentially a clunking sound as the suspension bottoms out or extends rapidly.
  2. Sway Bar Links/Bushings: These components connect the sway bar to the suspension. Worn or broken sway bar links or deteriorated bushings are a very common source of clunking noises over bumps. They are relatively inexpensive to replace.
  3. Ball Joints: Lower ball joints connect the control arm to the steering knuckle. If they wear out, they can cause clunking, looseness in the steering, and uneven tire wear. You might also feel a vibration.
  4. Control Arm Bushings: The control arms pivot on bushings. If these rubber bushings crack or wear out, they can allow excessive movement, leading to clunking and a less stable ride.
  5. Tie Rod Ends: While more commonly associated with steering looseness, severely worn inner or outer tie rod ends can sometimes contribute to clunking noises.

When to See a Shop:

  • Safety Concern: Any significant suspension noise or degradation in ride quality should be addressed promptly. Suspension components are crucial for vehicle control and safety.
  • Professional Inspection: A qualified technician can lift the vehicle, inspect all suspension components for wear, looseness, or leaks, and pinpoint the exact source of the noise and rough ride. They can perform a 'shake test' to identify loose parts. There are typically no OBD codes directly related to mechanical suspension wear, so a physical inspection is essential.
