Expect to pay roughly $320 to $840 if you replace all four ignition coils with aftermarket parts, or about $560 to $1,200 if you opt for OEM coils; replacing a single faulty coil typically runs in the $80 to $210 range when you include labor. Prices vary by engine, brand, and local labor rates.
Understanding the ignition coil system in the 2012 Cruze
The 2012 Chevy Cruze uses coil-on-plug ignition in its four-cylinder engines, so there is one ignition coil per cylinder. When a coil fails or a misfire is detected, a diagnostic trouble code (DTC) can illuminate the check engine light and trigger a misfire warning. Replacing coils is a straightforward job for a shop, but prices depend on whether you buy aftermarket parts or OEM/Delphi/ACDelco equivalents, as well as how many coils are replaced at once.
Engine options and coil layout
Most 2012 Cruzes with a 1.8L engine or the 1.4L turbo have four coils, one for each cylinder. The coils sit on top of the engine and are typically accessed without removing major components, but access can vary by engine bay layout and any heat shielding. If a single coil is bad, a shop can replace just that coil; if multiple coils are deteriorating, replacing all four is common for reliability.
Cost breakdown
The following estimates reflect common market prices in the United States and include both parts and labor. They will vary by region, shop, and part choice.
- Aftermarket ignition coil (per coil): typically $40–$90
- OEM/Delphi/ACDelco ignition coil (per coil): typically $100–$180
- Labor rate (per hour): typically $80–$120
- Typical labor time to replace all four coils: about 2–4 hours
Using these ranges, replacing all four coils with aftermarket parts generally runs about $320–$840, while using OEM-type coils can run roughly $560–$1,200, depending on exact part prices and labor duration. If you’re only replacing a single faulty coil, expect roughly $80–$210, depending on part choice and whether any additional components (like spark plugs) are changed at the same time.
Cost scenarios
Here are common situations you might face, with typical total ranges to help you budget.
- Replace all four coils with aftermarket parts: about $320–$840.
- Replace all four coils with OEM-type coils: about $560–$1,200.
- Replace a single faulty coil (including labor): about $80–$210.
- Replace coils and spark plugs together (common if plugs are worn): add roughly $20–$80 per plug for parts plus labor.
These figures assume standard shop labor rates and do not include any diagnostic fees, state taxes, or shop add-ons like disposal fees. If a diagnostic is required after a trouble code is read, some shops roll it into the repair price; others charge a separate diagnostic fee.
Saving money and avoiding surprises
To keep costs predictable, consider these practical steps before authorizing work.
- Ask for a written, itemized estimate that separates parts from labor and includes any diagnostic fees.
- Get quotes from multiple shops to compare prices for both aftermarket and OEM options.
- Ask whether the price includes spark plugs; if plugs are worn, replacing them at the same time can save future labor charges.
- Consider whether you truly need all four coils replaced at once; if only one coil is faulty and the others test fine, you may save money by doing a targeted replacement.
- Check warranties on parts and labor; some shops offer a limited warranty (e.g., 12 months/12,000 miles).
Being proactive about options and warranties can help you avoid sticker shock and ensure you get reliable, long-term results from the repair.
