Chevrolet Cruze Ignition Coil Guide: Symptoms, Brands, and Replacement (2010-2019)
Experiencing misfires or a rough idle in your Cruze? Your ignition coil pack is a likely culprit, especially on the 1.4L Turbo engine.
- Ignition coil failure is a very common issue on 1.4L Turbo Cruze engines, causing misfires (P0300-P0304) and a rough idle.
- Replacement is extremely easy (1/5 difficulty) and can be done in under 20 minutes with a T30 Torx bit.
- Always replace spark plugs at the same time to prevent premature failure of the new coil.
- Stick with OEM (ACDelco) or premium aftermarket brands (Delphi, NGK, Bosch) for the best reliability.
Signs of a Failing Ignition Coil in a Chevy Cruze
Ignition coil failure is a very common problem on the 1.4L Turbo engine used in the 2010-2019 Cruze, often happening after 100,000 miles. When the coil pack starts to go bad, the symptoms are hard to ignore. The most common sign is a Check Engine Light, which may be solid or flashing. A flashing light indicates a severe misfire that can quickly damage your expensive catalytic converter, so you should stop driving immediately.
Other symptoms include:
- Engine Misfires: The car may shake, stumble, or run erratically, especially when you accelerate or when idling at a stoplight. This feels like a shudder or vibration through the car. 🎬 Watch this diagnosis of misfires and coil pack issues.
- Rough Idle: Your car may vibrate noticeably when it's stopped but still in gear.
- Poor Acceleration: The car will feel sluggish and slow to respond when you press the gas pedal.
- Reduced Fuel Economy: An engine that isn't running efficiently will burn more gasoline.
- Gasoline Smell: A bad coil can cause unburnt fuel to enter the exhaust, creating a raw gas smell.
Known Issues & Recalls
While there are no specific recalls for the ignition coil itself on the 2010-2019 Cruze, ignition coil failure is a widely documented common issue, particularly for the 1.4L Turbo engine. Sometimes, a leaking valve cover gasket can cause oil to pool in the spark plug tubes, which will ruin the ignition coil boots and cause the new coil to fail prematurely. Always inspect for oil leaks when replacing the coil. 🎬 See how to replace a leaking valve cover gasket. Additionally, some aftermarket thermostat housings have been known to leak coolant into the wiring harness, which can short out and melt the ignition coil on cylinder 1. If you are repeatedly replacing coils, inspect the coolant temperature sensor connector for any signs of green coolant residue.
Choosing the Right Aftermarket Ignition Coil
When shopping for a new ignition coil for your Cruze, you'll find many brands. ACDelco is the Original Equipment Manufacturer (OEM) for General Motors. This means it's the same brand the car came with from the factory. For a critical and known failure part like this, sticking with proven quality is your best bet.
Tier 1: OEM & Premium Aftermarket
These brands are known for their reliability and are often the original equipment suppliers. They are the safest choice for the failure-prone 1.4L engine.
- ACDelco: As the OEM supplier, this is a direct replacement for the factory part. It's the benchmark for quality and fit.
- Delphi: Another top-tier OEM supplier for many manufacturers. Delphi parts are known for excellent quality and are a trusted alternative to ACDelco.
- NGK: While famous for spark plugs, NGK also makes high-quality ignition components. They were an OEM supplier for these coil boots and offer reliable replacement coil assemblies and repair kits.
- Bosch: A well-respected German brand known for high-quality automotive electronics and ignition parts.
Tier 2: Reputable Aftermarket Brands
These brands offer a good balance of quality and value. They are a solid choice for drivers on a budget who still want a dependable part.
- Standard Ignition (SMP): A long-standing brand in the aftermarket with a reputation for producing reliable parts.
- Hitachi: An established OEM supplier for many Japanese vehicles, known for quality electronics.
- Spectra Premium: Offers a wide range of aftermarket parts and is generally considered a reliable choice.
Tier 3: Economy Brands
These brands focus on providing the lowest price point. While tempting, be aware that for a part known to fail on the Cruze, a cheaper coil may not last as long as a premium one, potentially costing you more in the long run if you have to replace it again.

Pro Tip: Replace Spark Plugs at the Same Time
The ignition coil sits directly on top of the spark plugs. Since you already have the coil removed, it is highly recommended to replace the spark plugs at the same time. Worn or incorrectly gapped spark plugs can put extra strain on the new ignition coil, causing it to fail sooner. Always use high-quality Iridium spark plugs, like those from ACDelco or NGK, for the best performance and longevity.

Frequently Asked Questions
Can I replace just one bad coil on my Cruze?
No. The 2010-2019 Chevrolet Cruze with the 1.4L or 1.8L engine uses a single ignition coil pack assembly that houses all four coils in one unit. If one coil fails, the entire assembly must be replaced.
Is it hard to replace the ignition coil on a Chevy Cruze?
No, this is one of the easiest repairs you can do. The ignition coil is located directly on top of the engine and held in by just two T30 Torx bolts. The entire job can be done in less than 20 minutes with basic tools, making it a great DIY task to save money on labor.
🎬 Follow this walkthrough to replace your plugs and coils.Why do ignition coils fail so often on the Chevy Cruze?
Failures are often due to heat and vibration from the engine, which can cause the insulation inside the coil to break down over time. Other causes include worn-out spark plugs that increase resistance, and oil leaks from the valve cover gasket that contaminate the coil boots.
What are the OBD-II codes for a bad ignition coil?
The most common codes are P0300 (Random/Multiple Misfire) and P0301, P0302, P0303, or P0304 (Misfire Detected in Cylinder 1, 2, 3, or 4, respectively). You may also see codes like P0351, which points more directly to a fault in the ignition coil circuit.
