** The GMC repair market in the Metuchen area is characterized by strong competition between local, high-quality independent shops and the regional dealership network. Metuchen itself hosts a few long-standing general repair shops (like Metuchen Service Center) that are trusted for general maintenance and common issues. However, for the highly specialized services—particularly Duramax diesel and Allison transmission work—the most reputable specialists are located in the surrounding industrial areas of Edison, Avenel, and Somerset. These providers have carved out a niche by investing in specialized training and equipment. The average quality is high, as the market demands expertise for the complex systems in modern GMC trucks. Pricing is typically 20-35% lower than at the local GMC dealerships, which is a primary driver for owners to seek out these specialists. For Denali-specific luxury and electronic features, the dealership often remains the go-to for warranty and programming work, but the independent specialists are fully capable of handling the underlying mechanical and drivetrain components shared across trims.
