2017-2020 Chevrolet Sonic Wheel Cover: Guide to the Bolt-On Hubcap
This guide covers the unique bolt-on wheel covers for the 15-inch steel wheels, including common issues like cracking, and how to properly inspect and install a used replacement.
- This wheel cover (Part No. 94538398) ONLY fits 2017-2020 Chevrolet Sonic models with 15-inch steel wheels.
- It uses a unique bolt-on system with five plastic caps that thread onto the lug nuts; it is not a snap-on cover.
- When buying used, check for cracks around the lug nut holes and confirm if the plastic fastening caps are included.
- Installation is very easy and requires only a lug wrench; do not overtighten the plastic caps to avoid cracking them.
Symptoms of a Failing or Damaged Wheel Cover
The symptoms of a bad wheel cover are almost always visual or audible. Since it's not a mechanical part, failure won't affect how your car drives, but it can be a nuisance or a sign that it's about to fall off.
- Visible Cracks or Breaks: The most common failure is physical damage. Cracks, especially around the lug nut holes or on the spokes, are a clear sign of failure. This is often caused by curb impacts or from being overtightened.
- Rattling or Clicking Noises: If a wheel cover is loose, it can rattle or make a clicking sound as the wheel rotates. This often happens if the plastic fastening caps are broken, missing, or not tightened properly.
- Discoloration or Peeling Finish: Over time, the silver painted finish can be damaged by harsh cleaning chemicals, road salt, and sun exposure, leading to peeling, fading, or a dull appearance.
- Missing Cover: The most obvious symptom is that the wheel cover is simply gone. While the bolt-on design is more secure than snap-on types, a significant impact or improper installation can still cause it to detach.
Warning: While a missing wheel cover doesn't stop you from driving, it's important to check your lug nuts if you find one has fallen off. A loose wheel cover could be a symptom of loose lug nuts, which is a critical safety issue.
Buying a Used 2017-2020 Sonic Wheel Cover
A used OEM wheel cover is often the best value, providing the exact fit and finish of the original part. When buying a used one, careful inspection is key.
What to Check Before You Buy
- Verify Compatibility: This is the most important step. This wheel cover, part number 94538398, only fits 2017-2020 Chevrolet Sonic models with 15-inch steel wheels. You can confirm your wheel size by reading the numbers on your tire's sidewall. Look for a number like 'P195/65R15'. The 'R15' indicates a 15-inch wheel. This cover will not fit older Sonic models, or any model with 16-inch or 17-inch alloy wheels.
- Inspect for Cracks: Carefully check the entire surface, but pay special attention to the area around the five lug nut openings. This is the highest stress area. Flex the cover slightly to reveal any hairline cracks that might not be immediately visible.
- Check the Rear Mounting Points: Flip the cover over. While it doesn't have traditional clips, ensure the plastic structure around the lug holes is intact and not broken or worn away.
- Look for Scuffs and Scratches: Minor scuffs from curbs are common on used wheel covers and are often just cosmetic. However, deep gouges can weaken the plastic and may lead to cracks later on.
- Ask About the Fastening Caps: This wheel cover is held on by five plastic, threaded caps that screw onto the lug nuts. These are often lost or damaged. Ask the seller if the caps are included. If not, you will need to source them separately.
Pro Tip: A used OEM wheel cover is almost always a better choice than a cheap, universal aftermarket one. The OEM part is designed for the specific bolt-on system, ensuring it fits securely and the color matches other wheels perfectly. Universal snap-on covers will not work with this vehicle's retention system.
Cost Comparison
Prices for wheel covers can vary significantly based on condition and source. Here is a general breakdown of what to expect for a single wheel cover:
| Part Type | Estimated Price (Single Cover) | Notes |
|---|---|---|
| New OEM (Dealer) | $65 - $95 | Guaranteed fit and finish, but the most expensive option. |
| New Aftermarket | $35 - $55 | Made to look like the original, but may have slight differences in color or material quality. Ensure it is a 'bolt-on' style replica, not a universal 'snap-on'. |
| Used OEM | $25 - $50 | The best value. Provides original quality and fit at a lower price. Condition can vary. |
Installation Guide
Replacing this wheel cover is a simple DIY job that requires no special tools.
- Installation Difficulty: 1/5
- Estimated Time: 5-10 minutes per wheel
- Tools Needed: Lug wrench (the one from your car's trunk kit works perfectly)
Step-by-Step Replacement
- Remove the Old Cover: Use the lug wrench to unscrew the five black plastic fastening caps. They turn counter-clockwise just like a regular nut. Once the caps are off, the wheel cover will pull straight off the wheel.
- Position the New Cover: Align the new wheel cover with the wheel. There is a small cutout for the tire's valve stem; make sure it lines up correctly. The cover should sit flat against the wheel.
- Install the Fastening Caps: Thread the five plastic caps back onto the lug nuts by hand. Hand-tighten them in a star pattern to ensure the cover seats evenly.
- Final Tightening: Use the lug wrench to give each cap a final snug turn (about 1/8 to 1/4 turn). Be careful not to overtighten, as this can crack the plastic caps or the wheel cover itself. The caps just need to be snug enough to hold the cover securely.
Known Issues, Recalls, and TSBs
There are no specific recalls or Technical Service Bulletins (TSBs) issued by Chevrolet or the NHTSA for the wheel covers on the 2017-2020 Sonic. Any issues are typically related to wear and tear or external damage.
- Plastic Fastening Cap Breakage: The most common point of failure is the plastic caps that hold the cover on. They can become brittle over time and crack during removal or installation, especially if over-tightened or if an impact wrench is used.
- Curb Damage: Like any wheel cover, they are susceptible to scratches and cracks from hitting curbs.
Frequently Asked Questions (FAQ)
Is this the same as a hubcap?
Yes, the terms 'wheel cover' and 'hubcap' are often used interchangeably. Both refer to the decorative cover placed over a steel wheel.
Will this fit my Sonic if I have aluminum alloy wheels?
No. This wheel cover is specifically designed to fit over the 15-inch black steel wheels that came standard on some trim levels. It will not fit on any factory alloy wheel.
Do I need to take the whole wheel off to replace the cover?
No. The wheel can remain on the car. You only need to remove the plastic fastening caps that thread onto the lug nuts.
Can I buy just the plastic fastening caps?
Yes, the plastic fastening caps are typically available as a separate part from GM dealers or online parts stores. It is a good idea to have a few spares on hand.
Why did my wheel cover fall off if it's a 'bolt-on' style?
While more secure than snap-on covers, it can still come off. This could happen if the plastic caps were not tightened properly, if several caps were broken or missing, or if a significant impact (like hitting a large pothole) cracked the cover's mounting points.
