Certified GM Repair Expertise

As a certified GM Collision Repair Network member, Killen’s Smash Repairs meets strict training and facility requirements set by GM Australia. From modern body construction and high-strength steels to advanced safety systems and electronics, we repair each vehicle to factory condition.

Our certification also extends to new EV and hybrid platforms, including the impressive Cadillac Lyriq, representing the next generation of GM vehicle technology.

Why Certification Matters

  • Maintains GM safety and crash performance standards
  • Protects your vehicle’s manufacturer warranty
  • Ensures the use of genuine parts and OEM-approved materials
  • Restores performance, appearance and resale value

Our 3,800m² purpose-built repair facility is designed for precision, efficiency and manufacturer compliance. Every stage of the repair process, from disassembly to refinishing, is completed under controlled conditions.

Facility features:

  • Structural alignment bays with OEM-approved measurement systems
  • Dedicated aluminium and composite repair zones
  • Two PPG-certified spray booths with digital colour-matching

These advanced facilities allow us to service everything from everyday Holdens to high-performance HSV and imported GM models.

Genuine GM Parts and PPG Refinishing Systems

We use 100% genuine GM parts sourced through official channels to guarantee a perfect fit, long-term durability and uncompromised vehicle performance.

Our refinishing process uses PPG-approved paint systems, matching GM’s exact colour, gloss and durability standards. Every job is completed in a temperature-controlled booth to achieve an immaculate, lasting finish.

The benefits:

  • Genuine Holden, Chevrolet, HSV and GM components
  • Seamless colour matching and finish accuracy
  • Corrosion protection and durability assurance
  • Lifetime Guarantee on all paint and repair work

Structural and EV Repairs

Modern GM vehicles use complex combinations of high-strength steels, alloys and composite materials. Our certified technicians are trained in GM’s structural repair procedures, including:

  • Panel bonding and spot welding to OEM standards
  • Full chassis and subframe measurement
  • Sectioning and corrosion control
  • ADAS calibration for safety and driver assistance systems

We are also certified to handle EV platforms, including high-voltage isolation, battery removal and refitting, and post-repair diagnostics for models such as the Cadillac Lyriq.

Warranty Protection and Compliance

Every GM repair at Killen’s Smash Repairs is carried out using official GM repair data and genuine components. This approach ensures full warranty compliance and reinstates factory crash performance and safety.

Before final delivery, each vehicle undergoes a full electronic scan and quality inspection to confirm system integrity and function, the same process followed in GM-authorised facilities worldwide.

Pickup & Drop-Off Service

We offer a professional pickup and delivery service across NSW and QLD for all GM vehicles, ensuring safe and secure transport from your location to our certified facility. Our team manages every step of the process for convenience and peace of mind.

Your Right to Choose Your Repairer

Many insurance policies include a “Choice of Repairer” clause, allowing you to nominate a certified repairer like Killen’s Smash Repairs. This ensures your GM vehicle is repaired using genuine parts and approved procedures.

If your policy doesn’t include this option, your vehicle may be directed to a non-certified repairer, which can impact quality and warranty protection. Always confirm your policy details before lodging a claim.
