Behind Every Webb Auto Group Service Center: Certified Technicians and Genuine Parts

Across Webb Auto Group’s five dealerships — Webb Hyundai Highland, Webb Hyundai Merrillville, Genesis of Schererville, Webb Chevy Oak Lawn, and Webb Chevy Plainfield — the service departments share a common foundation even though each one is built around a different brand. Every service center is staffed with manufacturer-certified technicians, stocked with genuine parts, and equipped with the specific diagnostic tools each brand requires. This guide looks at what that standard actually means for drivers across Northwest Indiana and Chicagoland, and how to find the right service center for your vehicle.

The Shared Service Standard Across Webb Auto Group

Webb Auto Group operates five dealerships across Northwest Indiana and Chicagoland, each representing a different manufacturer — Webb Hyundai Highland and Webb Hyundai Merrillville for Hyundai, Genesis of Schererville for Genesis, and Webb Chevy Oak Lawn and Webb Chevy Plainfield for Chevrolet (with GMC, Buick, and Cadillac service also available in Plainfield). Despite the brand differences, every location holds its technicians to the same standard: manufacturer certification, genuine parts, and brand-specific diagnostic equipment.

What Manufacturer Certification Actually Means

Manufacturer certification isn’t a one-time credential — it’s ongoing training tied to each brand’s current model lineup, including newer systems like hybrid and electrified powertrains, advanced driver-assistance features, and updated infotainment platforms. A technician certified on a brand’s 2022 lineup isn’t automatically qualified on a 2026 model without additional training, which is why each Webb service department invests in continuing education for its technicians rather than treating certification as a box to check once.

Why Genuine Parts Matter for Warranty Coverage

Genuine parts are manufactured to the exact specification of the components a vehicle shipped with, which matters most for anything connected to safety systems, emissions, or the powertrain. Using non-genuine parts on certain repairs can affect warranty coverage on related components, so every Webb Auto Group service advisor can confirm which repairs require genuine parts before work begins — regardless of which of the five dealerships you visit.

Service Departments at Each Webb Rooftop

Each Webb dealership’s service department is built around its specific brand’s requirements. Webb Hyundai Highland and Webb Hyundai Merrillville both offer Hyundai-certified service covering the brand’s full lineup, including hybrid and electrified models. Genesis of Schererville’s service center is staffed specifically for Genesis vehicles, including the brand’s Electrified models. Webb Chevy Oak Lawn services Chevrolet vehicles, while Webb Chevy Plainfield extends that coverage to GMC, Buick, and Cadillac as well.

Brand-Specific Diagnostic Tools

Modern vehicles rely heavily on onboard computers and sensors, and diagnosing an issue correctly requires the manufacturer’s own diagnostic software in most cases. Each Webb Auto Group service department is equipped with the diagnostic tools specific to the brands it services, which means technicians can read the same fault codes and access the same technical bulletins the manufacturer uses internally — something not every independent shop can offer.

When to Schedule Service Regardless of Brand

Across every brand Webb Auto Group services, a few warning signs mean it’s time for an appointment rather than waiting: a dashboard warning light, unusual noises while braking or turning, a noticeable pull to one side, vibration at speed, or fluid leaks under the vehicle. These are worth acting on quickly no matter which Webb rooftop services your vehicle.

Choosing the Right Service Center for Your Vehicle

The simplest rule is to match your vehicle’s brand to its corresponding Webb service center — Hyundai owners to Webb Hyundai Highland or Webb Hyundai Merrillville, Genesis owners to Genesis of Schererville, and Chevrolet, GMC, Buick, or Cadillac owners to Webb Chevy Oak Lawn or Webb Chevy Plainfield depending on which brands each location services. Choosing the brand-matched location ensures your vehicle is serviced by technicians trained specifically on its systems.
