Can you add blind-spot monitoring to a Chevy Silverado?

Yes. Blind-spot monitoring can be added to a Chevy Silverado, either through a factory option on many trims or via dealer/aftermarket installations, depending on the model year and configuration.

Blind-spot monitoring on the Silverado typically goes by Lane Change Alert with Side Blind Zone Alert (SBZA) and is often paired with Rear Cross Traffic Alert (RCTA). These features use sensors to detect vehicles in adjacent lanes and alert the driver via mirrors and/or dashboard indicators. Availability varies by year, trim level, and packaging, so the first step is to check your truck’s options and compatibility.

What blind-spot monitoring on the Silverado involves

In Silverado models that support it, blind-spot monitoring is part of a broader suite of driver-assistance features. SBZA alerts you to vehicles in the adjacent lane when you signal a lane change, while RCTA alerts you to vehicles crossing behind you when you’re reversing. The system is typically integrated with exterior mirrors that show amber indicators and with a vehicle-wide safety package that may include other features such as forward collision alert or automatic braking on certain trims and years.

Ways to add blind-spot monitoring

There are multiple routes to add this feature, depending on your Silverado’s year and trim. The following options cover the common paths people take.

Factory-installed option: On many mid- to higher-trim Silverado models, Lane Change Alert with Side Blind Zone Alert and Rear Cross Traffic Alert are available as part of Safety or Technology Packages. If your vehicle is equipped with these packages or you upgrade to them, BSM is integrated with the existing mirrors and warning systems.

Dealer-installed or GM accessory retrofit: For some model years, GM offered a dealer-installed Blind Spot Monitoring retrofit kit. This path can add SBZA/RCTA through updated mirrors and wiring harnesses, but availability varies by year and dealer.

Aftermarket systems: Independent shops offer universal or Silverado-specific BSM solutions, including mirror-based units or bumper/sensor kits. These can be installed alongside the vehicle but may affect warranty coverage and require professional integration to work with existing safety systems.

Each option has trade-offs in cost, integration, and warranty. Factory or dealer-installed solutions tend to offer the smoothest integration with existing systems and warranties, while aftermarket options may be more flexible or affordable but require careful vetting.

Considerations before installing

Before committing to a BSM installation, consider these practical factors to ensure compatibility and value.

Year and trim compatibility: Not all Silverado models support BSM, and retrofit options may be limited to certain years or configurations. Confirm with a dealer or GM parts catalog for your VIN.

Warranty and insurance impact: Factory or dealer-installed packages typically preserve warranty; aftermarket installations can affect warranty terms and may influence insurance rates.

Cost and installation complexity: Factory options price and install at the dealership; aftermarket or retrofit kits vary in cost and may require more extensive installation, including mirror replacements or wiring work.

System integration: Ensure the chosen option works with other safety systems you have (e.g., lane-keeping assist, radar cruise control) to avoid false alerts or conflicts.

Careful planning helps avoid compatibility issues and ensures you get the intended safety benefits without compromising the truck’s other systems.

What to do next

To proceed, take these steps to confirm availability and costs for your Silverado:

Check your exact model year, trim, and current option packages in the owner’s manual or on the GM online parts catalog to see if SBZA/RCTA is offered for your truck.

Consult your local Chevrolet dealer or salesperson about factory or dealer-installed retrofit options for your VIN. Ask for a written quote and installation timeline.

If considering an aftermarket system, obtain a reputable installation quote and verify compatibility with existing safety systems and warranty terms.

Being thorough at this stage helps ensure a smooth upgrade that enhances safety without surprises later.

Summary

Blind-spot monitoring can be added to many Chevy Silverado models, primarily through factory or dealer-installed options on supported years and trims. If your Silverado doesn’t come with SBZA/RCTA, you may explore a GM retrofit kit (where available) or reputable aftermarket solutions, keeping in mind compatibility, warranty, and cost. Always verify the exact fit for your VIN with a dealer to ensure proper integration with the truck’s safety systems.

How much does it cost to add blind spot monitoring?

Adding blind spot detection can cost anywhere from $200 to over $1,000, depending on the type of system and whether you install it yourself or have a professional do it. DIY kits can range from $75 to $300, while professional installation typically starts at around $200 for a basic system, with more advanced or factory-style systems costing $899 or more installed.
Cost breakdown

Aftermarket kits: The kits themselves range from $75 to over $1,000, with more affordable options being less accurate.
DIY installation: You can save money by installing a kit yourself, but it can be a complex process.
Professional installation: This adds to the cost, with a professional installation starting around $200 and extending to over $1,000 for more advanced systems.

Factors that influence the price

System complexity: Simple radar sensor systems are cheaper, while those with cameras and more advanced features are more expensive.
Accuracy and reliability: More advanced systems with higher accuracy and reliability cost more.
Your car: The cost can vary based on your vehicle. Some cars may have pre-wiring for these systems, making installation easier and potentially cheaper.
Dealer vs. independent shop: A dealership may have higher prices for both parts and labor compared to an independent audio or car accessory shop.

Key takeaway

If you are looking for a more affordable solution, an aftermarket kit with professional installation is a good option.
For a more factory-like experience and higher accuracy, a higher-end aftermarket system with professional installation is the way to go, but it will be more expensive.

Can you add blind spot monitoring after purchase?

Yes, if your car does not have a blind spot sensor, you can install this technology.

What year of Silverado to stay away from?

You should be wary of certain years, particularly the 2014, 2015, and 2017 models, which are frequently cited for numerous issues, including transmission, fuel system, and airbag problems. Other years to approach with caution include 2005, 2007, 2008, 2012–2013, and 2019, due to engine, transmission, or electrical system problems.
Years to be cautious of

2005: Engine and electrical system issues, including excessive oil consumption.
2007: Fuel system malfunctions, leading to erratic fuel gauge readings and poor fuel efficiency.
2008: Mechanical problems and issues with the Active Fuel Management (AFM) system.
2012–2013: Transmission and engine problems, with owners reporting excessive oil consumption and vibrations.
2014: A high number of recalls and reported issues, particularly with airbags, transmission, and the air conditioning system.
2015: Continued issues with the fuel sensor, leading to inaccurate fuel gauge readings.
2017: Transmission problems, as reported by owners.
2019: The first year of a new generation that experienced numerous early problems.

Why these years are problematic

Recalls: Years like 2014 and 2015 had a high volume of recalls and owner complaints across various systems.
Transmission Issues: The introduction of an 8-speed gearbox in some models, particularly the 2014, led to clunking sounds and premature failure.
Engine and Fuel System: Some models experienced engine problems like oil consumption or issues with the fuel delivery system.
Electrical and Sensor Problems: Inaccurate fuel gauge readings were common in models like 2015, and other electrical issues were reported in various years.
Safety Concerns: Problems with airbags not deploying correctly were reported in some models, posing a safety risk.
