A Practical Guide to Replacing the Engine Mounts on a 2009-2018 Chevrolet Traverse
If your Traverse is shaking or making clunking noises, a bad engine mount is the likely culprit.
- Symptoms of a bad mount on a Traverse include intense vibration at idle, and clunking noises when accelerating or shifting.
- The Traverse uses four mounts; if one has failed, the others are likely worn and should be inspected or replaced.
- For best results and to avoid a rough ride, use a premium hydraulic mount from a brand like ACDelco instead of a cheaper, solid rubber alternative.
- Replacing a mount is a moderately difficult DIY job that requires safely supporting the engine.
Is Your Traverse's Engine Mount Failing?
Engine mounts wear out over time from constant heat and stress. When they fail, the symptoms are hard to ignore. Watch for these common signs in your 2009-2018 Traverse.
Common Failure Symptoms
- Excessive Vibration: The most common symptom is a strong vibration felt in the steering wheel, floor, or seats, especially when the SUV is idling in Drive or Reverse.
- Loud Noises: You may hear a distinct "clunk" or "bang" from the engine bay when you accelerate from a stop, shift from Park to Drive, or brake suddenly. This is the sound of the engine shifting and hitting its limits.
- Visible Engine Movement: With the hood open and the vehicle safely in Park, have a helper briefly rev the engine. If you see the engine rock or lurch more than an inch or two, 🎬 Watch: How to tell if your motor mounts have failed the mounts are likely worn out.
Choosing the Right Aftermarket Engine Mount
When shopping for a new engine mount, you'll find a wide range of quality and price. For a part this critical to your driving comfort, choosing the right brand matters.
Brand Quality Tiers
Tier 1: Premium Aftermarket (ACDelco)
ACDelco is General Motors' own parts brand, and their products are considered original equipment (OE) quality. Choosing an ACDelco mount is the safest bet for a perfect fit, proper vibration damping, and long-term durability that matches the part your Traverse came with from the factory. While it's the most expensive aftermarket option, it eliminates the risk of poor performance that can come with cheaper brands.
Tier 2: Standard Aftermarket (Anchor, Westar, DEA)
Brands like Anchor, Westar, and DEA are popular, budget-friendly choices. They offer a significant cost saving compared to ACDelco. However, quality can be inconsistent. Some owners and mechanics report that these mounts may not absorb vibrations as well as the original, or that they may fail more quickly. A good strategy is to consider these brands if you are on a tight budget or if you plan on replacing all four mounts at once as a set, which can be very cost-effective.
Tier 3: Economy (Pioneer Cable, Store Brands)
These are the lowest-priced options available. While tempting, they carry the highest risk of premature failure, poor fit, or inadequate vibration control. These are best avoided unless the vehicle's age and condition don't justify the cost of a higher-quality part.
Known Issues, Recalls, and Service Bulletins
As of early 2026, there are no specific recalls or Technical Service Bulletins (TSBs) from Chevrolet or the NHTSA related to engine mount failure on the 2009-2018 Traverse. Failures are typically due to normal wear and tear from age and mileage.
Replacement Costs for a Traverse Engine Mount
The total cost depends on whether you do it yourself or hire a shop, and which part you choose. The front and passenger-side mounts are the most common to fail.

Frequently Asked Questions
How many engine mounts does the Chevy Traverse have?
The 2009-2018 Traverse uses a four-point mounting system: a front mount, a rear mount, a passenger-side torque strut mount (sometimes called a shock mount), 🎬 See this video to locate all four Traverse motor mounts and a driver-side transmission mount.
Should I replace all engine mounts at once?
It's a good practice. When one mount fails, it puts extra stress on the others, causing them to wear out faster. If you're paying for labor to replace one, it can be cost-effective to replace the others at the same time, especially the other main load-bearing mount.
Is an ACDelco mount really better than cheaper brands?
For this vehicle, yes. The main engine mounts are hydraulic and designed to absorb the specific vibrations of the 3.6L V6 engine. Cheaper, solid rubber mounts often fail to control vibrations properly, leading to a rough ride. Sticking with the OE design from ACDelco is highly recommended for ride quality.
What happens if I don't replace a bad engine mount?
Ignoring a failed mount will lead to a very uncomfortable ride with severe vibrations. More seriously, the excessive engine movement can damage other components, including radiator hoses, exhaust pipes, wiring harnesses, and even the transmission.
