GM ANZ Releases Updated Genuine Parts Definition And New Positioning Statements

The GM Australia and New Zealand (GM ANZ) Aftersales team has issued an updated definition of GM Genuine Parts and released new positioning statements.

According to the release, a GM Genuine Part is defined as:

  • Parts that are designed, validated and engineered by General Motors or its associated entities; sourced through the GM ANZ authorised supply chain that are subject to warranties given by GM ANZ.
  • The replacement parts approved by General Motors for General Motors produced vehicles, including, but not limited to Chevrolet, Cadillac, Corvette, GMC and Holden.

“When it comes to repairs, it’s important to use parts you know and trust,” said Paul Rietveld, Director Aftersales at GM ANZ. “When using GM Genuine Parts, you’re provided with this peace of mind.

“We are serious about the safety of our customers and their right to have GM Genuine Parts fitted to their vehicles. GM Genuine Parts sold through the GM ANZ authorised supply chain can be trusted to be GM Genuine Parts, are fully ADR-compliant where applicable and backed by a factory warranty.”

GM ANZ also announced the release of position statements relating to ADAS considerations and windscreen replacement.

“In a similar vein, maintaining and updating positioning statements is important, as it enables our network and partners who service and repair GM vehicles to ensure they keep informed with the latest developments,” said Rietveld.

There have been additions to previously released information, including identifying requirements related to advanced driver-assistance systems and windscreen replacement.


“The overall integrity and performance of a vehicle’s ADAS is dependent on maintaining the design specifications of each component of the safety system,” said GM ANZ.

“Aftermarket or non-GM Genuine Parts and accessories, reconditioned or salvage parts may have different material or dimensional specifications than what was designed, tested and validated for use with ADAS and are not approved for use by General Motors.

“The overall operational integrity of ADAS features is dependent on maintaining its inherent design specifications. The use of aftermarket or non-GM Genuine parts and accessories in ADAS sensor areas including but not limited to the front bumper, front grill, below the front grill, licence plate covers, headlamps, windshield, front and rear side panels, mirrors, rear camera lens, and rear bumper area is not recommended due to the potential for degradation of ADAS feature functionality.

“Addition of protective covers, protective film, decorative / cosmetic wraps, stickers, window tint, magnets, hood protectors, push bars, bicycle racks, cargo racks, light bars, [and] over-sized roof cargo can potentially all adversely affect ADAS system feature performance.

“Non-GM Genuine lift or lowering kits, wheel rims and tyres, suspension, steering and other components or modifications that impact ride height, alignment angles and vehicle dynamics and handling are not recommended. Covering or any modification to the windshield blackout is not recommended. Any of these types of modifications are not recommended due to the potential for degradation of ADAS feature functionality.”


“GM Genuine branded glass is designed, engineered, tested, and validated to internal and government mandated standards and is the only GM-approved equivalent to the original equipment glass,” said the company.

GM ANZ stated that:

  • General Motors does not approve the use of aftermarket or non-GM Genuine original equipment glass.
  • Aftermarket glass may have different material, dimensional, and clarity specifications than what was designed, engineered, tested, and validated for use with ADAS and may lack General Motors installation quality controls.
  • Many GM original equipment glass parts contain enhanced acoustic dampening technologies integrated into the glass assembly. Aftermarket glass may not be equipped with these features, which may result in increased wind, road, and engine noise entering a vehicle’s occupant compartment.

“Consumers and repairers should be wary of using parts sourced from non-authorised outlets,” said Rietveld.
