GM’s Certified Collision Repair Network is not a single certification; it is a layered program.
Heritage Collision earns a Basic certification first, then adds tiers on top of it: an Internal Combustion Engine Specialty tier, a Battery Electric Vehicle Basic tier, and a Fleet tier. A body shop that only holds the Basic tier is not equipped the same way as one that earned BEV certification, and most never know that distinction exists at all.
Heritage Collision is audited by a third-party GM uses to verify certified body shops. If a gap is found during an audit, GM gives a body shop 60 days to resolve it or lose the certification. This means an active GM Certified Repair Network credential reflects that we meet the standard now, not years ago.
When you bring your Chevrolet, GMC, Buick, or Cadillac to Heritage Collision, you are getting a shop verified for the tier your vehicle actually requires: gas, hybrid, or electric.
Drive with confidence knowing your vehicle is repaired right.

WHY DO GM OWNERS CHOOSE HERITAGE COLLISION?
Because GM’s vehicles are not one platform with different badges, a Silverado, a Cadillac CT5, and an Equinox EV each have their own repair requirements.
A body shop only certified at the basic tier is not necessarily equipped for all three, like Heritage Collision.
Manufacturer Trained GM Certified Collision Repair
Manufacturer Trained Means Heritage Collision centers’ technicians’ GM training covers both the Internal Combustion Engine Specialty and Battery Electric Vehicle Basic tiers, kept current as GM’s Ultium lineup expands and as GM updates its documented repair procedures.
Here is a detail almost no local body shop explains, and Heritage Collision does. Super Cruise® is not a hands-free system that works everywhere; it’s only on specific LiDAR-mapped divided highways that GM has verified over several hundred thousand miles across North America.
Super Cruise® is extensively tested on Michigan roads that customers drive daily.
What does this mean for your GM repair?
After a collision, it must be recalibrated to restore camera and radar accuracy. GM Super Cruise® only works on roads the system is mapped for. Knowing the difference between a calibration issue and a mapped road limitation is part of a customer’s vehicle expectations.
Compliance with GM’s Basic program, plus any specialty tiers.
Internal Combustion Engine Specialty, Battery Electric Vehicle Basic, or Fleet, each with its own training and tool requirements, and a 60-day window to correct any gap found during the audit or lose the GM certification.
Structural repair on Chevrolet, GMC, Buick, and Cadillac models follows GM’s documented procedures for the specific steel and aluminum construction used in those models.
A Silverado’s frame repair requirements are not the same as those for a Cadillac’s aluminum-intensive body, and certification at the correct tier confirms a body shop actually has the equipment for both, not just one.
We use the factory guidelines. We’ll get it right.
Ultium powered vehicles, the Equinox EV, Blazer EV, and Silverado EV, use a wireless battery management system, meaning the pack does not rely on a traditional wiring harness the way earlier EV batteries did.
That is a real design difference, and it changes how a technician should diagnose a high-voltage fault after a collision.
There have been public reports of high-voltage system faults on some Ultium vehicles, which is exactly why accurate diagnosis before choosing a repair path matters.
Did you know the GM ADAS system requires recalibration after any impact?
At Heritage Collision, we recalibrate the ADAS with factory methods after an impact.
GM’s driver assistance technology is not a single system across the lineup. Super Cruise® in particular only operates on a large network of over 600,000 miles of compatible roads across the U.S. and Canada. These roads are pre-mapped with high-definition data and must have clear lane markings and good visibility for sensors and cameras.
Meanwhile, GM’s broader Driver Confidence and Buick, GMC Driver Confidence suites offer camera and radar-based features across a wider range of trims without hands-free capability.
That means if you select Heritage Collision, we know how to recalibrate your vehicle using only the correct methods.

GM CERTIFIED REPAIR QUESTIONS
You’ve got questions, we’ve got answers.
No. Michigan law gives you the legal right to choose your own repair facility, regardless of your insurer’s preferred vendor list.
Heritage Collision works directly with all insurance carriers at both our Ann Arbor and Canton locations.
It means Heritage Collision holds GM’s Basic certification plus additional tiers on top of it, including the Internal Combustion Engine Specialty tier and the Battery Electric Vehicle Basic tier.
Not every certified body shop holds both. A shop with only the Basic tier is not equipped the same way as one that also earned BEV certification.
GM audits certified body shops through a third party.
If a gap is found, the shop has 60 days to resolve it or lose the certification.
An active credential reflects that we meet the standard now, not that we met it once years ago.
No. Structural repair follows GM’s documented procedures for the specific steel and aluminum construction used in each model.
A Silverado’s frame repair requirements are different from a Cadillac’s aluminum intensive body, and holding certification at the correct tier confirms a body shop actually has the equipment for both.
Yes. Ultium powered vehicles use a wireless battery management system, which is a real design difference from earlier wired EV batteries.
Heritage Collision auto body technicians are trained specifically on how that changes high voltage fault diagnosis after a collision, so the repair path is chosen correctly from the start.

Heritage Collision will apply corrosion protection as standard procedure, not an add on.
