A Nissan Sentra Owner's Guide to Engine Mounts (2021-2025)
Experiencing vibrations or hearing clunking noises in your Sentra? A bad engine mount could be the problem.
- A known issue (TSB NTB23-018) exists for rattling noises caused by the passenger-side engine mount on 2021-2022 Sentras.
- Common symptoms are excessive vibration at idle and clunking noises during acceleration.
- For best results and to avoid future issues, using genuine Nissan (OEM) replacement mounts is highly recommended over budget aftermarket brands.
- Ignoring a failed mount can lead to damage to other components like hoses, wiring, and axles.
Is Your 2021-2025 Sentra Vibrating or Making Noise?
If you're noticing new vibrations in the steering wheel, floor, or seats, or hearing a clunking sound when you accelerate, your engine mounts might be failing. These parts are designed to wear out over time, but some 2021-2022 Sentra owners have experienced these issues earlier than expected. In fact, Nissan released a Technical Service Bulletin (TSB) for this specific problem.
Known Issue: TSB for Front End Noise
Nissan issued TSB NTB23-018 for some 2021-2022 Sentra models that develop a rattle or knock from the front when driving over bumps or turning. This noise, which can be mistaken for a suspension problem, is often caused by a faulty passenger-side engine mount insulator. If your car exhibits these symptoms, a technician can verify if this TSB applies.
Symptoms of a Failing Engine Mount in a Nissan Sentra
A bad engine mount will make its presence known. Here are the most common signs:
- Excessive Vibration: This is the number one symptom. You'll feel a noticeable vibration at idle, which may smooth out once you're moving. It might get worse when the air conditioning is on.
- Clunking or Thumping Noises: Loud clunks or thumps from the engine bay when you accelerate, decelerate, or shift gears are a classic sign. This is the sound of the engine moving too much and hitting other components.
- Engine Movement: A healthy engine should barely move. If you have a helper safely rev the engine in park while you watch under the hood, you might see the engine rock or lift significantly 🎬 Watch: How to diagnose and test for bad engine mounts if a mount is broken.
Choosing a Replacement: OEM vs. Aftermarket
When it comes to engine mounts for your Sentra, the quality of the part matters immensely. The choice between Original Equipment Manufacturer (OEM) and aftermarket parts can have a big impact on your driving experience.
- OEM (Nissan): These are the same parts your car was built with. They are designed specifically for the Sentra's vibration characteristics. Forum discussions among Nissan owners consistently show that OEM mounts provide the best fit, performance, and longevity. While they cost more upfront, they are less likely to cause problems down the road.
- Aftermarket (e.g., Anchor): Aftermarket brands offer a budget-friendly alternative. However, for a part like an engine mount, cheap is not always better. Many mechanics and vehicle owners report that value-grade aftermarket mounts, such as those from Anchor, use harder rubber compounds that don't absorb vibrations well. This can result in vibrations that are even worse than with the old, failed mount. While they may be an option if you're on a tight budget and plan to sell the car soon, be prepared for a potential compromise in ride quality.
Pro Tip: Given the known issues and owner feedback, using a genuine Nissan OEM replacement mount is the recommended path for a lasting, vibration-free repair on a 2021-2025 Sentra.

Frequently Asked Questions
How many engine mounts does my Sentra have? 🎬 See this video showing the motor and transmission mount locations
Like most front-wheel-drive cars, the Sentra typically has three or four mounts that support the engine and transmission. This usually includes a passenger-side mount, a transmission mount (driver's side), and one or two lower torque struts (often called 'dog bone' mounts) to control rocking.
Can I replace a Sentra engine mount myself?
Yes, if you have mechanical experience and the right tools. The lower torque struts are generally the easiest, requiring basic hand tools. 🎬 Watch: Step-by-step guide to replacing a Sentra torque rod The side mounts are more complex as you will need a jack to support the engine's weight safely while you unbolt the mount. Always use jack stands and follow proper safety procedures.
Is there a recall for the engine mounts on the 2021-2025 Sentra?
No, there are no active safety recalls for engine mounts on the 2021-2025 Nissan Sentra. However, Nissan has acknowledged a potential issue with the passenger side mount through a Technical Service Bulletin (TSB).
If one mount is bad, should I replace all of them?
When one mount fails, it puts extra stress on the others, which can cause them to fail sooner. If your car has higher mileage, it's a good idea to inspect all the mounts. If you're paying for labor, it can be cost-effective to replace them all at once, but it's not always necessary. At a minimum, replace the failed mount and carefully inspect the others for cracks or wear.
