2010-2018 Acura RDX Grille: A Guide to Facelifts, Options, and Replacement

Understanding the Three Generations of RDX Grilles (2010-2018)

The grille for the Acura RDX from 2010 to 2018 is not a one-size-fits-all part. There are three distinct, non-interchangeable versions that buyers must be aware of. Installing the wrong grille will result in improper fitment, and on newer models, may interfere with advanced safety features.

2010-2012: First Generation (Facelift)

For the final years of the first-generation RDX, Acura updated the styling, including the front grille. This version is unique to these three model years.

• Design: Features a prominent satin/silver 'beak' design with a black mesh background.
• Key Part Number: The main grille assembly is often identified by OEM part number 71121-STK-A02.
• Compatibility: This grille only fits 2010, 2011, and 2012 RDX models. It is not compatible with earlier (2007-2009) or later (2013+) models.

2013-2015: Second Generation (Pre-Facelift)

The second-generation RDX debuted with a completely new body and a redesigned grille. This style was used for the first three years of the new generation.

• Design: A wide, silver-painted grille with horizontal slats and a large Acura emblem.
• Key Part Number: The primary OEM part number for this grille is 71121-TX4-A01.
• Compatibility: This grille fits only 2013, 2014, and 2015 RDX models. It cannot be used on 2010-2012 or 2016-2018 vehicles.

2016-2018: Second Generation (Facelift with AcuraWatch Option)

In 2016, the RDX received a significant facelift, which included a new grille design and the introduction of the AcuraWatch suite of safety features. This created two different grille versions for this period.

• Standard Grille (Without AcuraWatch): This grille has a 3D "diamond" or jewel-eye appearance in the background, behind the main Acura 'A' logo and wing. The key OEM part number is 71121-TX4-A51.
• AcuraWatch Grille (With Radar): For models equipped with Adaptive Cruise Control (ACC) and Collision Mitigation Braking System (CMBS), the grille features a solid, smooth plastic panel in the center instead of the open mesh. This panel protects the radar unit. Using a standard grille on a vehicle with radar will cause the system to malfunction.

Symptoms of Grille Failure

Failure of an RDX grille is almost always due to physical damage or cosmetic degradation. There are no moving parts to wear out, but its forward-facing position makes it vulnerable.

• Cracked or Broken Plastic: The most common failure is cracking or shattering from impacts with road debris, animals, or minor parking lot collisions. This compromises the vehicle's appearance and can leave the radiator exposed.
• Peeling Chrome or Paint: Over time, the chrome or painted finish on the grille can bubble, peel, or flake off due to weather exposure and rock chips. This is a cosmetic issue but can be unsightly.
• Broken Mounting Tabs: The plastic tabs that hold the grille to the bumper cover are fragile. They can break during a minor impact or if the grille is removed improperly, leading to a loose, rattling fit.
• Damaged Radar Cover (2016-2018): On models with AcuraWatch, a crack or deep scratch on the solid center panel can interfere with the radar sensor's operation, potentially disabling the ACC and CMBS systems and triggering warning lights on the dashboard.

Buying a Used Grille: What to Inspect

A used OEM grille is an excellent alternative to an expensive new part, often providing the same fit and quality for a fraction of the price. However, careful inspection is key.

Inspection Checklist:

1. Confirm the Year Range: First and foremost, ensure the grille is from the correct vehicle group: 2010-2012, 2013-2015, or 2016-2018. They are not interchangeable.
2. Check for AcuraWatch (2016-2018): If you have a 2016-2018 model, determine if you need the standard or radar-compatible grille. A vehicle with AcuraWatch will have a solid panel in the center of the grille.
3. Inspect All Mounting Tabs: This is the most critical inspection point. Carefully check the back of the grille for any broken, cracked, or repaired mounting tabs and clip points. Even one broken tab can cause poor fitment or rattling.
4. Examine the Finish: Look for signs of peeling chrome, deep scratches, or stress marks (white-ish lines in the plastic) from impacts. Minor pitting from normal road use is acceptable, but large areas of damage are not.
5. Check the Emblem: Verify if the Acura emblem is included and in good condition. Sometimes these are sold separately and can be expensive to replace.
6. Verify Integrity of Radar Panel: For AcuraWatch grilles, run your hand over the solid center panel. Ensure there are no cracks, deep gouges, or signs of delamination that could affect the radar sensor behind it.

Known Issues, Recalls, and TSBs

Searches of the National Highway Traffic Safety Administration (NHTSA) database and for Technical Service Bulletins (TSBs) did not reveal any recalls or bulletins directly related to the grille assembly itself for the 2010-2018 Acura RDX. Most issues are cosmetic, such as peeling chrome, as reported by owners in forums. While there are numerous recalls for the RDX, none pertain to the grille being a point of failure. Some TSBs may require removal of the grille for access to other components, like the intercooler.

Cost Comparison

Prices for an Acura RDX grille can vary significantly based on the year, condition, and source.

Note: Prices are estimates as of late 2023 and can vary based on supplier, condition, and included components (like emblems or moldings). Shop labor is not included.

Installation Guide

Replacing the grille on a 2010-2018 Acura RDX is a moderately difficult task that is feasible for a DIYer with basic tools. The primary challenge is that it typically requires removing the front bumper cover to access the grille's mounting screws and clips.

• Difficulty: 3 out of 5
• Estimated Time: 1.5 - 2.5 hours
• Tools Needed: Socket set, screwdrivers (Phillips and flathead), plastic trim removal tools, pliers.

General Steps:

1. Remove Upper Clips: Open the hood and remove the plastic clips holding the upper radiator cover/shroud in place.
2. Detach Bumper Cover: Remove the screws and clips securing the bumper cover in the wheel wells and along the bottom edge.
3. Disconnect Fog Lights (if applicable): Before fully removing the bumper, disconnect any wiring for fog lights or sensors.
4. Remove Bumper Cover: Gently pull the sides of the bumper cover away from the fenders to release the clips, and then pull the entire assembly forward and set it on a soft surface to prevent scratches.
5. Unbolt the Grille: From the back of the bumper cover, unscrew the Phillips head screws that secure the grille assembly.
6. Release Clips: Carefully release the plastic tabs holding the grille to the bumper. A trim removal tool is helpful here to avoid breaking them.
7. Install New Grille: Swap the emblem if necessary, then clip and screw the new grille into place.
8. Reassembly: Reinstall the bumper cover in the reverse order of removal.
