Honda Ridgeline Engine Mount Failures and Replacement Guide (2016-2025)
Feeling a vibration or hearing a clunk in your Ridgeline? Your engine mounts could be the problem.
- Excessive vibration at idle and clunking noises when shifting are the most common symptoms of a bad mount.
- For 2018-2019 models, a specific 'chirping' noise often points to a failed rear engine mount, as documented in TSB 20-068.
- OEM mounts offer the best performance for ride comfort but are significantly more expensive than aftermarket options.
- Aftermarket brands like Anchor and DEA are budget-friendly but may increase cabin vibration and have a shorter lifespan.
Is Your Ridgeline Shaking or Making Noise? It Could Be an Engine Mount.
A failed engine mount is a common issue that can cause a range of uncomfortable symptoms. Because the mounts are made of rubber and are sometimes filled with fluid, they wear out over time from constant heat and stress. Ignoring a bad mount can lead to more vibration, noise, and potentially damage other components connected to the engine.
Honda Ridgeline Engine Mount Known Issues
Technical Service Bulletin (TSB 20-068): Honda issued a TSB for some 2018-2019 Ridgeline and Pilot models for a "chirping" sound coming from the cabin when the engine is warm and the transmission is in Drive. This is caused by premature internal wear in the rear engine mount. The fix is to replace the rear mount with an updated part (Honda Part No. 50810-TZ5-A03). If you have an affected model year and hear this specific noise, the rear mount is the likely culprit.
Choosing the Right Aftermarket Engine Mount
When replacing an engine mount, you have a choice between Original Equipment (OEM) parts from a Honda dealer and aftermarket parts from brands like Anchor or DEA. Here’s an honest breakdown for your Ridgeline:
- OEM (Original Equipment Manufacturer): These are the same parts your truck was built with. For a part like an engine mount, where vibration control is key, OEM is often the best choice for a smooth, quiet ride. They are designed to work perfectly with your Ridgeline's V6 and VCM system. However, they are the most expensive option.
- Aftermarket (Anchor, DEA): These brands offer a much more affordable alternative. However, the quality can be inconsistent. Forum discussions among mechanics and vehicle owners often report that budget aftermarket mounts may use harder rubber, which can cause more cabin vibration than the original part. They might also not last as long as an OEM part. An aftermarket mount can be a good budget-conscious choice if you're willing to accept a potential compromise in ride comfort and longevity.
Pro Tip: Your Ridgeline has multiple engine mounts (typically front, rear, and side). They don't always fail at the same time. If you're on a budget, you can replace only the failed mount. However, if one has failed, the others may not be far behind. Mechanics often recommend replacing them as a set for the best long-term results.
Cost to Replace a Honda Ridgeline Engine Mount
The total cost depends on whether you do the work yourself or hire a shop, and which parts you choose. Replacing an engine mount requires safely supporting the engine, making it a moderately difficult job.
| Part Type | Estimated Part Cost |
|---|---|
| New Aftermarket (e.g., Anchor, DEA) | $72 - $155 per mount |
| New OEM | $250 - $780+ per mount |
| Shop Labor | $315 - $600 |
Frequently Asked Questions
How many engine mounts does my 2016-2025 Ridgeline have?
The 3.5L V6 setup in the Ridgeline typically uses three or four mounts: a front mount, a rear mount, a side (passenger side) mount, and sometimes a transmission-specific mount.
Can I replace just one bad engine mount?
Yes, you can replace only the mount that has failed. This is a common way to save money. However, keep in mind that all mounts are the same age, and a failure of one puts extra stress on the others, which may cause them to fail sooner.
Are aftermarket mounts from Anchor or DEA good enough?
They are a functional, budget-friendly option. However, for sophisticated hydraulic mounts designed to minimize vibration, many owners and mechanics find that aftermarket parts don't provide the same level of smoothness as OEM parts and may not last as long. If your priority is restoring the original quiet ride, OEM is the recommended path.
What happens if I don't replace a bad engine mount?
Ignoring a failed mount will lead to progressively worse vibration and noise. In severe cases, the excessive engine movement can put stress on other parts like radiator hoses, exhaust pipes, and wiring, potentially leading to more expensive repairs down the road.
