Is Your Chevrolet Trax Shaking, Stumbling, or Losing Power?
Ignition coil failure is a common problem for the 1.4L turbo engine found in the 2013-2022 Chevrolet Trax. This part works hard under high heat and voltage, and over time, it can wear out. The good news is that diagnosing the issue is straightforward, and replacing the part is one of the easiest repairs you can perform on your vehicle. This article will walk you through the symptoms, part choices, and what to expect.
Symptoms of a Failing Ignition Coil
When the ignition coil pack begins to fail, the signs are usually obvious. Because it's a single assembly for all four cylinders, a failure can feel severe. You will likely experience one or more of the following issues:
- Check Engine Light: This is often the first warning. If the light is flashing, it signals a severe engine misfire that can quickly damage your expensive catalytic converter. If you see a flashing light, you should pull over as soon as it is safe and avoid driving the vehicle. 🎬 Watch this video to see how a P0300 misfire is diagnosed.
- Engine Misfires and Shaking: The most common symptom is a rough, shaking, or stumbling engine. This will be most noticeable when the car is stopped at a light (idling) or when you are trying to accelerate.
- Loss of Power: Your Trax will feel sluggish and weak because the engine isn't firing on all cylinders.
- Reduced Fuel Economy: An engine that misfires is inefficient and will burn more gasoline than usual.
- Gasoline Smell: In some cases, a failing coil can cause unburnt fuel to pass into the exhaust, which you might smell.
Pro Tip: Replace Spark Plugs at the Same Time
Worn-out spark plugs put extra strain on the ignition coil, and a failing coil can damage new plugs. For this reason, it is highly recommended to replace all four spark plugs when you replace the coil pack assembly. Also, inspect the spark plug wells for oil. A leaking valve cover gasket is a common issue that can allow oil to pool around the plugs, which will ruin the boots on your new coil pack.

While ignition coil failure is a widely reported issue among owners, there are no official recalls from Chevrolet or the NHTSA for this specific part on the 2013-2022 Trax. There was a recall for an issue with the ignition key reminder chime, but this is unrelated to the coil pack itself. A Technical Service Bulletin (TSB #PIP5657D) notes that a misfire can sometimes be caused by a broken spark plug insulator, so it's wise to inspect the old plugs during the job.
Choosing the Right Aftermarket Ignition Coil
Since you're replacing a known failure point, choosing a quality part is important. Aftermarket parts for the Trax ignition coil fall into a few quality tiers. Avoid the cheapest unbranded options, as forum members report they often fail prematurely.
Tier 1: OEM & Premium Aftermarket
These brands are known for quality and reliability and are often the original equipment manufacturer for GM. They are the safest bet for a long-lasting repair.
- Delphi: Widely considered to be an OEM supplier for many GM parts, making it a top-tier choice for fit and performance.
- Bosch: A world-renowned manufacturer of high-quality automotive components with a strong reputation.
- NGK: A leader in ignition system technology, known for making excellent coils and spark plugs.
Tier 2: Quality Aftermarket
These brands offer a good balance of price and quality and are a solid choice for most DIY repairs. Many come with good warranties.
- Standard Ignition (SMP)
- Hitachi
- Spectra Premium
- Walker Products
Tier 3: Economy Brands
These are budget-focused options. While they are the most affordable, their long-term durability can be a gamble. They may be suitable for a temporary fix or if the budget is the primary concern.

Frequently Asked Questions (FAQ)
Is it hard to replace the ignition coil on a Chevy Trax?

🎬 Follow this step-by-step walkthrough for a quick ignition coil replacement.Can I drive my Trax with a bad ignition coil?
You can drive for short distances if necessary, but it is not recommended. If the check engine light is flashing, the misfire is severe enough to send unburnt fuel into the exhaust, which can quickly destroy the catalytic converter, leading to a much more expensive repair.
Should I buy an OEM or aftermarket ignition coil?
For a critical part like this that is known to fail, it's best to invest in a quality part. An OEM part from the dealer or a premium aftermarket brand like Delphi, NGK, or Bosch is a reliable choice. While cheaper options exist, some owners report they do not last as long.
Why did my ignition coil fail?
Coils fail from a combination of heat, vibration, and high voltage stress over many miles. Failure can be accelerated by worn-out spark plugs, which increase the voltage required to create a spark, or by oil leaking from the valve cover gasket onto the coil boots.
