Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering suspension on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
CHEVROLET/GMC: SEE DOCUMENT SEARCH BUTTON FOR OWNER LETTER. ON SOME 2011-2012 TRUCKS, A GRINDING NOISE AND VIBRATION WOULD BE NOTICEABLE DUE TO THE REAR AXLE RIGHT HAND SIDE BEARING ADJUSTER CLIP AND BOLT MAY COME LOOSE INSIDE OF REAR AXLE. UPDATED 9/6/12. UPDATED 7/18/14. UPDATED 11/6/15.

The failure pattern owners describe
Frame corrosion dominates complaints about this truck. Multiple owners describe extensive rust and rot in the frame and undercarriage, with holes, cracks, and complete rot-through sections appearing well before normal. Several report the frame failing state inspection; one owner discovered it while trying to change shocks. A truck that passed inspection routinely years earlier failed with a hole in the frame despite garage storage. Repair shops tell owners the frame cannot be salvaged—replacement is the only option. One owner's running board fell off the vehicle because the frame attachment point had rusted away.
Front suspension failures include a wheel collapse at 69,000 miles (ball joint and retainer bar fractured), a lower control arm that snapped at 15,000 miles while climbing a dirt hill at 2 mph, and violent front-end vibration during braking that persisted after rotor repair. One owner experienced complete rear axle detachment at 70,000 miles; the vehicle had been inspected under suspension recall 11V007000 in 2011, but the dealer declined the repair both times.
A rear clunking over bumps was dismissed by dealers as normal backlash. One owner with truck marketing certification alleges the rear spring pack is undersized for the advertised GVWR, causing towing problems; Chevrolet refused to install higher-rated springs he requested.

Failure modes owners describe
Frame rust and corrosion
Extensive, accelerated rusting and corrosion of the frame and undercarriage, including holes, structural cracks, and complete rot-through in sections. Multiple owners report frame deterioration far exceeding normal expectations for the vehicle age. Running boards and other frame-mounted components have failed due to rust. Frame rated as unsafe by inspection stations and repair shops.
When: Reported at 10–15 years of age; some noted rusting within 2 years of ownership; many discovered during routine inspections or maintenance
Symptoms owners cite: Visible holes in frame; Peeling and flaking undercoating; Widespread corrosion on both sides of frame; Structural cracks in frame; Rot through inside frame walls; Frame attachment points compromised; Vehicle failed state inspection due to frame condition
Repairs/costs cited: Frame replacement required in most cases; repair shops stated corrosion cannot be repaired, only replaced. One owner reported hitch replacement due to rust, and shock mounting failure when attempting removal.
Rear axle detachment
Rear driver side axle and tire completely separated from the vehicle while in motion. Vehicle was previously inspected under NHTSA recall 11V007000 (Suspension) but dealer declined to perform repair, stating the vehicle did not require it. Repair was again denied after failure.
When: Approximately 70,000 miles
Symptoms owners cite: Rear axle and tire completely detached into oncoming traffic; Loss of steering control; Vehicle had to be towed
Repairs/costs cited: Vehicle not repaired; towed to owner's residence.
Recalls/TSBs owners mention: Recall 11V007000 (Suspension) was inspected in 2011; dealer denied repair at that time and again after the failure occurred.
Front suspension ball joint and control arm fracture
Front driver side ball joint, retainer bar, and lower control arm fractures causing wheel collapse or control arm failure at relatively low impact or low mileage.
When: Ball joint fracture at 69,000 miles; lower control arm snap at 15,000 miles (low-speed dirt hill)
Symptoms owners cite: Front wheel collapse while driving at 60 mph; Lower control arm snapped while driving uphill at low speed; Vehicle deemed destroyed in one case; Loss of vehicle control
Repairs/costs cited: One vehicle was deemed destroyed and not repaired. The other required front axle replacement per dealer diagnosis.
Recalls/TSBs owners mention: Manufacturer stated vehicle not included in any recall after lower control arm failure.
Front-end vibration during braking
Violent shaking and vibration in the front end when brakes are applied at highway speeds. Condition persists after brake rotor repair. Accompanied by premature tire wear.
When: First reported at 6,976 miles; vibration continued through at least 14,000 miles
Symptoms owners cite: Violent shake and vibration at front end during braking at 65 mph; Vibration persists after brake rotor repair; Premature tire wear; Ongoing brake problems
Repairs/costs cited: Brake rotors found out of round, turned downward, and repaired; vibration did not resolve.
Recalls/TSBs owners mention: Manufacturer was made aware but no resolution documented.
Rear suspension clunking and spring rating deficiency
Clunking noise from rear suspension over bumps. Additionally, owner with truck marketing certification alleges the rear spring pack is undersized relative to the GVWR rating: spring suppliers rate the combined spring pack at 2,850–3,000 lbs, but the rear axle GVWR is listed at 3,950 lbs, creating a 950–1,100 lb overrating. Owner requested springs from another model with a combined 4,050 lb rating; Chevrolet refused.
When: Clunking present during normal driving; spring rating issue identified by owner analysis
Symptoms owners cite: Clunking noise from rear when driving over bumps; Trailing/towing problems related to spring capacity; Dealer dismissed as normal backlash
Repairs/costs cited: Owner requested replacement springs with higher combined rating; Chevrolet refused the request.
Recalls/TSBs owners mention: Chevrolet refused to replace springs with higher-rated units.
