A Guide to the Starter for the 2014-2020 Chevrolet Impala
Having trouble starting your Impala? This guide covers common starter problems and how to choose the right replacement part.
- Always test the battery and check its connections before replacing the starter; symptoms can be identical.
- On the 3.6L V6 engine, the starter is difficult to access, requiring removal of the catalytic converter, which increases labor time and cost.
- Check for a loose positive cable at the starter motor, as a GM Technical Service Bulletin (20-NA-139) identifies this as a cause for a no-start condition.
- For long-term reliability, especially on the V6, consider a new, premium aftermarket starter over a remanufactured one due to the high labor cost of replacement.
Is Your Impala's Starter Failing?
A bad starter can leave you stranded. Before you replace it, make sure your battery is fully charged and the terminals are clean and tight. Starting problems can often be traced back to a weak battery, not a bad starter. If your battery is good, look for these common starter failure symptoms.
Common Symptoms of a Bad Starter:
- Single Loud Click: When you turn the key, you hear one loud click, but the engine doesn't crank. This often points to a failed starter motor or solenoid.
- No Crank, No Start: You turn the key, the dashboard lights come on, but nothing happens. The engine is silent.
- Grinding or Whirring Noise: You hear a grinding or high-pitched whirring sound during or after cranking. This can mean the starter gear isn't engaging properly with the engine's flywheel.
- Intermittent Starting: The car starts fine one day but refuses to start the next. This unpredictability is a classic sign of a starter on its way out.
- Engine Cranks Slowly: Even with a good battery, the engine seems to turn over very slowly, as if the battery is weak. This can be caused by a starter drawing too much electrical current.
Known Issues and Service Bulletins
General Motors has issued Technical Service Bulletins (TSBs) for starting issues on these vehicles. TSB #19NA256 addresses a grinding noise when starting or a starter that won't crank. Another bulletin, 20-NA-139, points to a no-crank condition caused by a loose positive battery cable connection at the starter itself. Before replacing the starter, it's a good idea to check that this connection is clean and tight, as it could be a simple fix.
Choosing the Right Aftermarket Starter
When replacing your Impala's starter, you have options beyond the expensive OEM part from the dealer. Aftermarket brands offer a balance of quality and value. Here’s a look at the brands available.
- Premium Aftermarket (Denso): Denso is a well-respected brand, often supplying original parts to many automakers. Choosing a new Denso starter is the closest you can get to OEM quality, known for reliability and long life.
- Standard New & Remanufactured (Remy, WAI Global): Remy and WAI Global are established aftermarket names. They offer both new and remanufactured starters. While generally reliable, some user reviews suggest that the lifespan of remanufactured parts can sometimes be unpredictable.
- Value Remanufactured (BBB Industries): BBB Industries is a major supplier of remanufactured parts to many auto parts stores. These offer a cost-effective solution, but quality can vary. They are a budget-friendly choice if you need to get your car back on the road.
Pro Tip: For the 2014-2020 Impala, especially the 3.6L V6 model where replacement is labor-intensive, investing in a high-quality new starter from a brand like Denso can save you from having to do the job again in a couple of years.
Estimated Replacement Costs
The cost to replace the starter in a 2014-2020 Impala varies based on the engine and the parts you choose. The 3.6L V6 is more expensive due to higher labor costs.
| Part or Service | Estimated Cost |
|---|---|
| New Aftermarket Starter | $131.87 - $257.12 |
| New OEM (GM Genuine Parts) Starter | $265 - $435 |
| Shop Labor | $140 - $205+ |
| Total Estimated Cost (Aftermarket Part + Labor) | $270 - $465+ |
Note: Labor costs can be significantly higher for the 3.6L V6 model because the catalytic converter must be removed for access. Total replacement costs at a repair shop can range from $426 to $847.
Frequently Asked Questions
Is it hard to replace the starter on a 2014-2020 Impala?
It depends on your engine. For the 2.5L 4-cylinder, the starter is located at the back bottom of the engine and is reasonably accessible. For the 3.6L V6, the job is much more difficult because the starter is behind the catalytic converter, which must be removed to gain access. This makes the V6 job challenging for a DIY mechanic.
How do I know if it's the battery or the starter?
If you can jump-start the car and it runs fine, the problem is likely your battery or charging system. If the car won't start even with a jump, or you just hear a loud click, the starter is the more likely culprit. Always test the battery first, as its symptoms can be identical to a bad starter.
Do I need a special starter for the start-stop system?
Some Impala models are equipped with an automatic start-stop feature. These systems require a more robust starter designed for frequent use. When ordering, ensure the part is specified for your vehicle's exact configuration, as a standard starter may fail prematurely in a start-stop vehicle.
Are there any recalls for the starter on my Impala?
There are no specific recalls for the starter motor on the 2014-2020 Chevrolet Impala. However, there was a recall for a poor electrical ground on the Power Steering Control Module on 2014 models, and electrical issues can sometimes cause starting problems. There is also a TSB related to a loose positive cable at the starter.
