My 2005 GMC canyon started having a groaning noise when turning sharply either way from a start or moving. I took it to the dealer who kept it and called to tell me it was defective body bolts, for which there was a bulletin. The parts had to be ordered directly from GMC. There it sits a week later, and I am without a vehicle, and I am very unhappy. GMC needs to overnight parts. *jb

What stands out
Of the 4 model years of GMC Canyon we track for body problems, this one carries the most owner complaints on file — 10.
No new NHTSA body complaint has been filed on this vehicle in over 19 years — the issue may be aging out of the active population.
The failure pattern owners describe
Buyer takeaway: 2005 GMC Canyons suffer from systemic frame rust that can compromise structural integrity and safety, with multiple owners reporting frame failure or rust-through at low to moderate mileage regardless of maintenance; defective body bolts also appear to be a known issue requiring dealer parts and service.
Owners of 2005 GMC Canyons report severe frame corrosion concentrated in the rear section, particularly around leaf spring hangers and the lower frame rails. The rust appears aggressive and localized—multiple owners describe rust-through holes and metal thinned to unsafe levels, even on trucks well-maintained and garaged during winter. The problem concentrates at lap seams in the frame construction, where water apparently traps and accelerates corrosion.
Mileage at discovery ranges from 13,000 to 140,000 miles, suggesting a design flaw rather than normal wear. One owner who inherited his vehicle at 13,000 miles found severe subframe rust during an oil change; another at 75,124 miles could not safely drive after rust-through was discovered. A dealer technician notes seeing this issue frequently and compares it to the Toyota frame recall.
When owners attempt repairs, mechanics recommend frame replacement rather than patching. Several trucks became total losses once frame rust was discovered. One owner experienced driveshaft failure when frame structural loss became acute. A separate issue involves defective body bolts causing groaning during sharp turns; the dealer bulletin requires GM-direct parts ordering, causing extended service delays.
One complaint notes the truck lacks a manual key entry lock on the passenger door.
Failure modes owners describe
Frame rust and structural failure at rear spring hanger area
Severe corrosion of the frame in the rear section, particularly around the leaf spring hangers and rear frame rails. Owners report rust-through holes, thin metal, and complete structural failure in localized areas. The rust often concentrates at lap seams where water traps, causing accelerated corrosion. Multiple owners report the frame became unsafe to drive and recommended for total replacement rather than repair.
When: Reported at 75,124 miles, 100,000 miles, 112,500 miles, 13,000 miles, 140,000 miles—wide variation suggests design flaw rather than mileage-dependent wear
Symptoms owners cite: Rust holes and pitting throughout frame undercarriage; Rust-through at leaf spring mounts and shackles; Frame rails thinned and corroded at lap seams; Frame collapse risk when lifted on hoist; Driveshaft breakage as secondary failure from frame structural loss; Loud boom noise when hitting road bumps (frame flex/failure); Groaning noise when turning sharply from start
Repairs/costs cited: Owners cite frame replacement as recommended repair; one repair involved defective body bolts requiring GM-ordered parts. Most vehicles deemed total loss or taken off road before repair attempted.
Recalls/TSBs owners mention: One owner stated GM was notified and referred to NHTSA. One dealer issued a bulletin for defective body bolts. No recalls or TSBs mentioned by owners.
Defective body bolts causing frame/body separation issues
Dealer bulletin identified defective body bolts as the source of noise and structural concern. Parts require direct ordering from GMC.
When: Reported during vehicle service, timing not specified by owner
Symptoms owners cite: Groaning noise when turning sharply from start or while moving
Repairs/costs cited: Defective body bolts must be ordered directly from GMC; dealer service experienced extended wait times (over one week)
Recalls/TSBs owners mention: Bulletin issued for defective body bolts
Missing exterior manual key entry lock on passenger door
Vehicle is not equipped with a manual key entry lock on the passenger-side door as expected.
Symptoms owners cite: No exterior manual key lock on passenger side door

Tl* the contact owns a 2005 GMC canyon. While the vehicle was at an independent mechanic for new tires, the technician noticed that the bottom of the frame was corroded and needed to be replaced. The vehicle was not repaired. The vehicle was not taken to a dealer. The manufacturer was notified of the failure and referred the contact to NHTSA. The approximate failure mileage was 140,000.
The left rear frame rail just in front of the left rear front spring shackle has rusted through and is no longer safe to drive the vehicle. There are holes through the lower portion of the frame rail. The sides of the same area have become very thin compared to the original thickness of the frame rail. Because of the location of the rust through at the spring shackle it was recommended a frame…

Common questions
How serious is the body problem on the 2005 GMC Canyon?
It's a documented issue but not catastrophic. 10 complaints have been filed. Repairs average $1,500 and most owners catch it before it causes a breakdown.
At what mileage does the body typically fail?
Across the 8 complaints that reported odometer mileage, most body failures cluster between 50,106 and 112,565 miles, with the median around 91,900. A quarter of owners report trouble before 50,106; a quarter make it past 112,565. Maintenance history matters more than the odometer alone — this is the reported failure window, not a guarantee.
What does it cost to fix?
Independent shops typically charge around $1,500 for body repairs on this vehicle. Dealer pricing tends to run 20-40% higher. The exact figure depends on the specific failure mode, parts availability, and your local labor rates. If you're outside factory warranty, an extended service contract often covers this category.
Are there any recalls related to body?
No active recalls currently cover body issues on this vehicle. The complaints filed represent owner-reported failures that haven't risen to the level of a manufacturer-issued recall — but they're still worth knowing about before you buy or budget for repairs.
