2017-2020 Chevrolet Sonic Grille: A Guide to RS and Non-RS Differences
This guide explains the critical differences between the RS and standard grilles to ensure you purchase the correct part for your 2017-2020 Sonic.
- The most critical factor is trim: grilles for RS and non-RS (LS/LT) models are NOT interchangeable without swapping the entire front bumper cover.
- When buying a used grille, the condition of the mounting tabs on the back is more important than minor cosmetic scuffs on the front.
- Replacement is a moderately difficult DIY job because the entire front bumper must be removed to access the grille.
- The Chevrolet bowtie emblem is almost always sold separately from the grille itself.
Variant Differences: RS vs. Non-RS Grilles
The single most important factor when purchasing a grille for a 2017-2020 Chevrolet Sonic is the trim package. The grilles for the sporty RS package and the standard (LS, LT) packages are visually distinct and are not interchangeable. Attempting to fit an RS grille on a non-RS bumper cover (or vice-versa) will fail, as the shapes and mounting points are different.
- RS Package Grille: Features a distinct, aggressive honeycomb mesh pattern. It has a more open and performance-oriented look. The upper grille for the RS is often identified by part numbers like GM1200737.
- Non-RS (LS/LT) Grille: Features horizontal slats. The upper grille typically has a prominent chrome trim piece across the middle, while the lower grille is matte black with horizontal bars. The upper grille is associated with part numbers like 94538130, while the lower grille without the RS package is part number 42496925.
Warning: Always verify if your Sonic has the RS package before ordering a grille. A forum user confirmed that to install a non-RS grille on an RS model, the entire front bumper cover must be swapped.
Symptoms of a Damaged Grille
Grille failure is almost always due to physical damage from road debris or a collision. Symptoms are typically visual.
- Visible Cracks or Holes: The most common symptom is visible damage from impacts with rocks, birds, or other road hazards.
- Broken or Missing Pieces: Sections of the grille, especially the slats or honeycomb mesh, can break off, leaving the radiator and condenser exposed.
- Poor Fitment or Gaps: If the mounting tabs are broken, the grille may become loose, vibrate, or show uneven gaps with the bumper or hood.
- Faded or Peeling Finish: The plastic can fade to a dull gray over time from UV exposure, and any chrome accents can peel or bubble, diminishing the vehicle's appearance.
Pro Tip: While a damaged grille is mainly cosmetic, a large enough hole can allow bigger debris to hit the A/C condenser or radiator. A small rock hitting a condenser at highway speed can cause a refrigerant leak, leading to an expensive A/C repair.
Buying a Used 2017-2020 Sonic Grille: What to Check
A used OEM grille is often a better choice than a cheap aftermarket one due to superior fit and material quality. When inspecting a used grille, pay close attention to the following:
- Confirm the Trim: First and foremost, ensure it's the correct grille for your RS or non-RS model. Compare the pattern (honeycomb vs. horizontal slats) to your existing grille.
- Inspect All Mounting Tabs: This is the most critical inspection point. Carefully check every tab and clip location on the back of the grille. Even one broken tab can cause a poor fit or a rattle. Look for stress marks (white-ish lines in the plastic) around the tabs, which indicate they have been bent and are weakened.
- Check for Cracks: Flex the grille slightly to reveal any hairline cracks that might not be obvious. Pay special attention to the areas around the screw holes and tab slots.
- Examine the Finish: Look for deep scuffs, rock chips, and any peeling on chrome trim pieces. While minor cosmetic issues are expected with a used part, significant fading or damage may not be acceptable.
- Ask About the Emblem: The Chevrolet bowtie emblem is often sold separately. Confirm with the seller if the emblem is included. If not, you will need to purchase one or transfer it from your old grille if possible.
Known Issues, Recalls, and Service Bulletins
There are no recalls or common Technical Service Bulletins (TSBs) directly related to the grille failing on its own for the 2017-2020 Chevrolet Sonic. Any issues with this part are almost exclusively the result of external factors like collisions or road debris. While many TSBs exist for the Sonic, none pertain to the design or function of the grille itself.
Cost of Replacement
Prices can vary based on supplier and condition. The following is an estimated cost breakdown:
| Part Type | Estimated Cost | Notes |
|---|---|---|
| New OEM (Dealer) | $240 - $420 | Price varies by upper/lower and RS/non-RS. For example, the non-RS lower grille (42496925) has an MSRP of over $410 but can be found for around $270 from online GM parts dealers. The RS upper grille is around $365. |
| New Aftermarket | $50 - $150 | Fit and finish can be inconsistent. Materials may be more brittle than OEM. |
| Used OEM | $75 - $200 | Offers the best value with OEM fit, but condition must be carefully inspected. |
| Shop Labor | $100 - $250 | Typically 1-2 hours of labor. The front bumper must be removed for replacement. |
Replacement Overview
Replacing the grille on a 2017-2020 Sonic is a moderately difficult job for a DIYer because it requires the complete removal of the front bumper fascia.
- Difficulty: 3 out of 5
- Estimated Time: 1.5 - 2.5 hours
- Tools Needed: T20 Torx driver, 7mm socket, 10mm socket, trim removal tools, flat blade screwdriver.
The general process involves removing screws and clips from the wheel wells, under the front of the bumper, and in the engine bay along the top of the fascia. Once the bumper is off the vehicle, the old grille is unclipped from the inside and the new one is snapped into place before reinstalling the bumper.
Part Numbers
Part numbers are crucial for ensuring you get the right part. Here is a breakdown of common numbers. Always double-check with the seller using your VIN.
| Part Description | OEM Number(s) | Partslink Number |
|---|---|---|
| Upper Grille (Non-RS, with Chrome) | 94538130 | GM1200736 |
| Upper Grille (RS, Honeycomb) | GM1200737 | |
| Lower Grille (Non-RS) | 42496925 | GM1036195 |
| Lower Grille (RS) | 42497011 | GM1036197 |
Frequently Asked Questions (FAQ)
Can I install an RS grille on my non-RS Sonic?
No, not without significant modification. The RS and non-RS grilles are shaped differently and mount to different bumper covers. To properly perform this swap, you would need to replace the entire front bumper cover with one from an RS model.
Does the grille come with the Chevrolet bowtie emblem?
Typically, no. Whether you are buying new or used, the emblem is usually considered a separate part. You will likely need to transfer your old emblem or purchase a new one.
How do I know if my 2017-2020 Sonic has the RS package?
The RS package includes several visual cues, such as a sport body kit, a rear spoiler, fog lights, and specific RS badging. For the grille itself, the easiest way to tell is that the RS has a black honeycomb mesh pattern, while the standard models have horizontal slats, often with a chrome bar.
Is it hard to replace the Sonic grille myself?
It is a manageable DIY project for those comfortable with basic tools, but it is more involved than on some other cars. The entire front bumper cover must be removed to access the grille clips. If you are not comfortable removing body panels, it is best to leave this job to a professional.
