Chevrolet Impala Starter Motor: A Guide for 2006-2010 Models
If your 2006-2010 Impala won't start, clicks, or cranks slowly, your starter might be the problem; here's how to choose the right replacement.
- A single 'click' with no crank is a classic symptom of a failed starter on this Impala.
- Before replacing the starter, check for engine oil leaks dripping on it, as this is a common cause of failure.
- Always test the battery and starter relay first to avoid a misdiagnosis.
- For maximum reliability, consider a new or remanufactured starter from ACDelco, the original equipment manufacturer.
Is Your Impala's Starter Failing?
A bad starter is one of the most common reasons a car won't start. For the 2006-2010 Chevrolet Impala, symptoms are usually very clear. Before you assume the starter is bad, always make sure your battery is fully charged and the terminals are clean. A weak battery can act just like a bad starter. You can get your battery and starter tested for free at most auto parts stores.
Common Failure Symptoms
- Single, Loud Click: You turn the key and hear one loud click, but the engine doesn't crank. This often means the starter solenoid is working, but the motor itself is not.
- No Sound at All: If you turn the key and nothing happens, the problem could be the starter, but it could also be the battery, ignition switch, or starter relay. The starter relay for this Impala is in the under-hood fuse box. 🎬 Watch this video to troubleshoot a no-start or relay issue.
- Slow, Labored Cranking: If the engine turns over very slowly, like the battery is weak, it can be a sign that the starter motor is wearing out and drawing too much power.
- Grinding or Whirring Noise: A grinding sound can mean the starter gear is damaged or not aligning correctly with the engine's flywheel. A high-pitched whirring or spinning sound without the engine cranking means the starter motor is running but not engaging the flywheel. 🎬 See a demonstration of what a failing starter sounds like.
Choosing the Right Aftermarket Starter
When shopping for a new starter for your Impala, you'll find a wide range of brands and prices. They generally fall into three categories.
Tier 1: OEM & Premium Aftermarket
These are the highest quality and most reliable options. They are designed to meet or exceed the original factory specifications.
- ACDelco: As the original equipment (OE) supplier for GM, ACDelco is the benchmark for fit and reliability. They offer both brand new "GM Genuine Parts" and professional-grade remanufactured options. Forum users have reported solving repeated starting issues by switching to an ACDelco starter after cheaper aftermarket units failed.
Tier 2: Performance Brands
These brands are designed for high-compression or modified engines. They offer more cranking power (torque) than standard starters. For a stock Impala, they are usually not necessary but are a high-quality option.
- Powermaster, MSD, Mr. Gasket, Proform: These brands specialize in high-torque and lightweight starters, often used in racing and performance applications. They are at the top of the price range but offer excellent power and durability.
Tier 3: Standard Aftermarket
These brands offer a good balance of price and quality, making them a popular choice for daily drivers. They are typically new units, not remanufactured.
- MPA, TYC, Bosch: These are well-known aftermarket manufacturers that produce reliable replacement parts that fit and function like the original. Many come with warranties and have undergone testing to ensure durability.

Frequently Asked Questions
Is it hard to replace the starter on a 2006-2010 Impala?
It is considered a moderately difficult job. Access is tight, and you'll be working from underneath the car. You will need to remove a plastic shield and possibly the oil filter to get enough room to work. The starter is held on by two 15mm bolts and has two electrical connections. If you have basic mechanic's tools and are comfortable working under your vehicle, it is a DIY-feasible job.

There are no specific recalls for the starter motor itself. However, there was a major recall for the ignition switch on 2006-2014 Impalas. A heavy keychain could cause the switch to move out of the 'run' position, shutting the engine off while driving. While not a starter issue, it is a critical safety recall related to the vehicle's electrical and starting system.
Can I just replace the starter solenoid?
On most modern starters, including the one for this Impala, the solenoid is attached to the starter motor and they are sold as a single assembly. While it's sometimes possible to replace just the solenoid, it's almost always easier and more reliable to replace the entire starter unit.
Do I need a special starter for the Impala SS 5.3L V8?
Yes, the starter for the V8 engine is different from the one used on the 3.5L and 3.9L V6 models. They are not interchangeable. Always confirm the part fits your specific engine when ordering.
