Guide to Replacing the Starter on a 2015-2022 GMC Sierra 1500
If your Sierra just clicks when you turn the key, this guide is for you.
- A single, loud click without the engine cranking is the most common sign of a bad starter on a Sierra 1500.
- Always test the battery and check connections first, as a weak battery can mimic starter failure.
- Replacement is a manageable DIY job for many owners, taking about 1-2 hours and saving significant labor costs.
- No major recalls exist for the starter, but be aware of TSBs for cold-weather starting issues on 2014-2015 models.
Is Your Sierra's Starter Failing?
A starter problem on the 2015-2022 GMC Sierra often gives you a warning before it fails completely. You might first notice it takes a couple of tries to start, which can quickly become a bigger problem that leaves you stranded. Before you assume the starter is bad, always check the battery first. A weak battery or corroded terminals can mimic the symptoms of a failing starter. Make sure your battery is fully charged and the connections are clean and tight.
Common Failure Symptoms
- Single Loud Click: The most common sign is a single, loud "click" from the engine area when you try to start it, but the engine doesn't turn over. This usually points to a bad starter motor or solenoid.
- No Sound at All: If you turn the key and nothing happens—no click, no crank—the starter could have completely failed.
- Slow or Struggling Crank: If the engine turns over very slowly, like it's struggling, the starter motor could be wearing out and drawing too much power.
- Grinding Noise: A grinding sound during or after starting can mean the starter's gear is not engaging correctly with the flywheel or is staying engaged too long. This can cause damage to both the starter and the flywheel.
- Intermittent Starting: The truck might start perfectly one day and refuse to start the next. This unpredictability is a classic sign of a starter on its way out.
Check the Battery First!
Many starting problems are caused by a weak or dead battery, not the starter. If your headlights are dim or you hear a rapid clicking sound, the battery is the likely culprit. Always test your battery and clean the terminals before replacing the starter.
Known Issues, Recalls, and TSBs
While there are no major recalls specifically for the starter motor on the 2015-2022 GMC Sierra 1500, GM has issued Technical Service Bulletins (TSBs) for related issues. TSB PIE0283 was released for 2014-2015 models concerning a no-crank condition in very cold temperatures (-7°C / 20°F or colder), where the starter was a suspected cause. Other TSBs for this truck generation address various electrical and no-start conditions that can sometimes be misdiagnosed as a bad starter, highlighting the need for careful diagnosis.

When your original starter fails, you don't have to go back to the dealer. New aftermarket starters offer a great balance of quality and value. They are designed to meet or exceed original equipment (OE) specifications and are often a more affordable choice for a daily-driven truck.
Here's a look at the available brands:
- Valeo: Valeo is a well-respected global supplier of original equipment parts, including starters. Choosing a Valeo part often means you are getting the same quality as the part that came with your truck from the factory. They produce 100% new units, not remanufactured.
- Remy (Delco Remy): With over a century of experience, Remy is a trusted name in starters and alternators, especially for commercial and heavy-duty applications. Their parts are known for durability.
- WAI Global: WAI Global manufactures new starters and tests them extensively for speed, torque, and durability. They are known for producing their own electronic components and offering good warranty protection.
- BBB Industries: BBB is a large and established player in the aftermarket, offering a wide range of new and remanufactured parts that provide a cost-effective solution.
New vs. Remanufactured
A "new" aftermarket starter is built from all-new components. A "remanufactured" starter has been rebuilt from a used core, with wearable parts like brushes and bushings replaced. For a critical part like a starter, a new unit from a quality brand like Valeo or WAI Global often provides the best long-term reliability and peace of mind.

Frequently Asked Questions (FAQ)
Can I drive my Sierra with a bad starter?
No. A failing starter is unreliable and will eventually leave you stranded without the ability to start the engine. It's best to get it replaced as soon as you notice symptoms.
Is replacing the starter a DIY job?
Yes, for those with moderate mechanical skill. The starter is located on the passenger side of the engine, and replacement involves disconnecting the battery, lifting the truck, removing a few bolts and electrical connections, and swapping the unit. It typically takes 1-2 hours.

A bad starter often causes a single, loud click, while a dead battery usually causes rapid, fast clicking or makes the headlights dim when you try to start the engine. If a jump-start gets the engine running, the problem is likely your battery.
Do I need to replace any other parts with the starter?
It's a good idea to inspect the battery cables and connections for corrosion or damage. Some mechanics recommend replacing the two starter mounting bolts, as they can stretch. Also, check the plastic pigtail connector for the solenoid, as it can become brittle and break during removal.
