Rear suspension sagging and rough ride on my 2023 Tucson XRT

Vehicle: 2023 Hyundai Tucson XRT

Hello everyone,

I've got a 2023 Hyundai Tucson XRT, and I've started noticing that the rear end seems to be sitting lower than it used to. It's not a huge difference, but it's definitely noticeable, especially when I have passengers or cargo in the back. Along with the sagging, the ride quality has become much harsher and bumpier, almost like the car is bottoming out over larger bumps.

The car only has about 15,000 miles on it, so I'm surprised to be having suspension issues already. I haven't overloaded it or anything like that. No warning lights are on the dash.

Has anyone with a newer Tucson or another Hyundai experienced premature rear suspension sagging or a significantly rougher ride? What could be the cause of this, and what should I be looking at? Any advice would be great!

Hi David,

It's definitely concerning to experience rear suspension sagging and a rough ride on a relatively new 2023 Hyundai Tucson XRT. While premature, these symptoms strongly suggest an issue with the rear suspension components.

Here are the most likely causes:

  1. Worn or Broken Coil Springs: Even on a newer vehicle, a defective or prematurely worn coil spring can lose its tension, causing the vehicle to sag. In some cases, a spring can even break, leading to a significant drop and harsh ride.
  2. Failing Shocks/Struts: The shocks (or struts, depending on the design) are responsible for dampening suspension movement. If they are failing, they won't absorb bumps effectively, leading to a bouncy or harsh ride. While they don't directly cause sagging, a completely blown shock can contribute to the feeling of bottoming out.
  3. Damaged Suspension Mounts/Bushings: If the mounts for the springs or shocks, or the various control arm bushings, are damaged or worn, it can affect the ride height and stability.
  4. Overloading (Less Likely for you): While you mentioned you haven't overloaded it, consistently carrying heavy loads can accelerate wear on suspension components.
  5. Manufacturing Defect: Given the low mileage, there's a possibility of a manufacturing defect in one of the suspension components.

Diagnostics:

  • Visually inspect the rear coil springs for any signs of breakage, cracks, or corrosion.
  • Look for any fluid leaks around the rear shocks, which would indicate a blown shock.
  • Compare the ride height of the rear to the front, and potentially to another similar Tucson if possible.
  • Push down on the rear of the vehicle; if it bounces more than once or twice, the shocks are likely worn.

When to See a Shop: Since your Tucson is a 2023 model, it should still be under factory warranty. This is the first thing you should check. Schedule an appointment with your Hyundai dealership immediately. Explain the sagging and rough ride. They will be able to diagnose the issue, and if it's a manufacturing defect or premature wear, it should be covered under warranty. Driving with compromised suspension can affect handling, tire wear, and overall safety, so don't delay. There are no OBD codes associated with mechanical suspension sagging.
