A Guide to the Starter Motor for the 2016-2020 Chevrolet Impala
Don't get stranded by a no-start condition—learn the signs of a failing starter in your Impala.
- A no-start condition is the ultimate symptom, but slow cranking and clicking sounds are early warnings.
- Always test your battery and check starter fuses/relays before replacing the starter to avoid a misdiagnosis.
- A Technical Service Bulletin (TSB PIP5180B) exists for some 2018 models with hard-starting issues.
- Aftermarket brands like ACDelco and MPA offer quality new replacements that can provide significant savings over OEM parts.
Is Your Impala's Starter Failing?
A starter motor problem can seem sudden, but the part often gives warning signs before it fails completely. A common mistake is confusing a bad starter with a dead battery. If your interior lights and dashboard are bright but the engine won't crank, the starter is a likely suspect. Here are the most common symptoms for a 2016-2020 Chevrolet Impala.
Common Symptoms of a Bad Starter
- Single, Loud Click: You turn the key, hear one loud click, but the engine doesn't turn over. This often means the starter's solenoid is engaging, but the motor itself isn't spinning.
- Rapid Clicking: A series of fast clicks when trying to start can point to a starter that's trying to engage but can't due to a weak battery or an internal failure.
- Engine Cranks Slowly: If the engine seems to struggle and turns over much slower than usual, the starter motor may be wearing out and losing its power.
- No Sound at All: If you turn the key and nothing happens—no click, no crank—it could be a failed starter solenoid, a bad ignition switch, or a blown fuse. Before assuming it's the starter, check the starter fuse (slot 12 in the under-hood fuse box). 🎬 Watch: How to find and check your starter fuse
- Grinding or Whirring Noise: A grinding sound during or after starting can mean the starter gear is not meshing correctly with the engine's flywheel or is failing to disengage. A whirring noise without the engine cranking means the starter motor is spinning but not engaging the flywheel at all.
First, Check Your Battery
The symptoms of a bad starter and a weak or dead battery are very similar. Before you buy a new starter, make sure your battery is fully charged and the terminals are clean and tight. A simple jump-start test can help diagnose the issue: if the car starts with a jump, your battery is the likely problem. If it still just clicks or won't crank with a jump, the starter is the probable cause.
Known Issues for the 2016-2020 Impala
While there are no widespread recalls for the starter motor on this generation of Impala, Chevrolet did issue a Technical Service Bulletin (TSB) for some 2018 models.
- TSB #PIP5180B: This bulletin addresses conditions of a hard start, extended crank time, or seeing black smoke from the exhaust during startup. While this could be related to other issues, it's something a technician can investigate if your car exhibits these specific symptoms.
Choosing the Right Aftermarket Starter
When your original starter fails, you have several options. For the 2016-2020 Impala, the factory part is a reliable, high-quality unit. However, new aftermarket starters can offer similar quality at a better price.
Brand Tiers: ACDelco and MPA
ACDelco: As General Motors' own parts brand, ACDelco is a trusted name. However, they offer different product lines that you should be aware of:
- GM Genuine / OE: This is the exact same part that was installed in your Impala at the factory. It offers the highest quality and a perfect fit, but also comes with the highest price tag.
- ACDelco Gold (formerly Professional): This is ACDelco's premium aftermarket line. These parts are built to meet or exceed OE specifications and are a reliable alternative to the more expensive OE part.
- ACDelco Silver: This is a more budget-friendly option, offering good quality for the price. It's a good choice for drivers looking for a reliable repair without the premium cost.
MPA (Motor Parts of America): MPA is a very large aftermarket manufacturer that supplies parts to many major auto parts stores. While they are well-known for remanufactured parts, they also produce new starters. A new starter from MPA is designed to be a direct-fit replacement, offering a balance of value and reliability. When choosing any aftermarket brand, always check the warranty information.
New vs. Remanufactured
This guide focuses on new aftermarket starters. A new part is made with 100% new components. A remanufactured part uses the original housing (the core), which is cleaned and inspected, and all internal wear items (brushes, bearings, solenoid) are replaced with new components. High-quality remanufactured starters from brands like Bosch or Carquest Premium can be a cost-effective and reliable option.
Cost of Replacing an Impala Starter
The cost to replace a starter motor depends on the part you choose and local labor rates. The job is moderately difficult, as the starter is in a tight spot on both the 2.5L and 3.6L engines.
| Item | Estimated Cost |
|---|---|
| Shop Labor | $140 - $205 |
| New OEM Starter Part | $265 - $435 |
| New Aftermarket Starter Part | $122 - $300 |
| Total Professional Replacement | $380 - $715 |
Frequently Asked Questions
Can I drive my Impala with a bad starter?
No. If the starter is completely failed, the engine will not start, leaving you stranded. If it is showing intermittent symptoms, it could fail without warning at any time. It is not safe to rely on a failing starter.
Can I replace the starter myself?
For an experienced DIYer, this is a possible job. The starter is located at the back of the engine, either near the bottom for the 2.5L or behind the catalytic converter on the 3.6L. Access is tight, and you may need to remove other components to get to it. You will need a good set of tools, including sockets and extensions, and a way to safely lift the vehicle. Always disconnect the battery before beginning work.
What's the difference between the 2.5L and 3.6L starter replacement?
The general process is similar, but the location and surrounding components differ. On the 2.5L I4 engine, the starter is at the back bottom of the engine, below the intake manifold. 🎬 See this 2.5L starter location and replacement walkthrough On the 3.6L V6, it is located behind the catalytic converter. 🎬 Watch: Step-by-step starter replacement for the 3.6L engine Both require working in a confined space.
Is a clicking sound always the starter?
Not always, but it's a strong indicator. A rapid clicking often points to a battery that has enough power to activate the starter's solenoid but not enough to turn the motor itself. A single, solid click is more likely to be a failed starter motor. Always test the battery first to rule it out.
