2007 GMC Sierra 3500HD
Recalls and owner complaints reported to NHTSA
Compared with the typical (middle) count of 98 complaints across the 8 model-year 2007 heavy-duty trucks we cover. Best-selling trucks naturally collect more complaints because more of them are on the road.
What owners should know
Covers 2007–2010 · 6.6L Duramax LMM diesel and 6.0L V8 gas · Updated 2026-10-01
The Chevy Silverado HD and GMC Sierra HD are mechanically the same trucks, so these notes cover both, in 2500HD and 3500HD. Engines are the 6.6L Duramax LMM diesel and the 6.0L V8 gas, with the Allison 6-speed automatic on diesels.
2007 was sold in two versions: the older-style "Classic" body and the new body style. These notes are about the new body. If you're looking at a 2007, check which one it is.
We counted 708 owner complaints filed with NHTSA for 2007, 2009 and 2010. For 2008, NHTSA files these trucks together with the half-ton Silverado and Sierra, so we can't separate their complaints and recalls. For a 2008, check recalls with the VIN at nhtsa.gov. Complaint counts show what owners report most often, not how many trucks have a problem.
At a glance
- Airbag recalls are the top complaint topic. Several passenger airbag recalls cover these years.
- Steering wear (idler arm, pitman arm, tie rods) is the most commonly discussed problem on owner forums.
- The Duramax LMM is generally well regarded. DPF clogging, EGR and transmission cooler line leaks are the commonly reported repairs.
- Cracked dashboards are very commonly reported.
Airbag recalls
Airbags come up in about 4 in 10 complaints (208 of 483 from identified engines), often from owners waiting on recall parts. GM recalled 2007–2008 trucks because the passenger airbag inflator can absorb moisture and rupture when it deploys (recalls 15V324000 and 20V011000), with more inflator recalls on 2009–2010 trucks. These are serious. Check that every one shows as completed.
Steering and front end
These trucks use independent front suspension with torsion bars, not a solid axle, so "death wobble" is rarely reported. Owners on diesel forums very commonly report worn idler arms, pitman arms and tie rods, which show up as loose or wandering steering and clunks. Lifted trucks or trucks with the torsion bars cranked up wear them faster.
When buying: have a helper turn the steering wheel back and forth with the engine running while you watch the idler and pitman arms for play.
6.6L Duramax LMM
Repair sources commonly report DPF clogging, EGR carbon buildup, transmission cooler line leaks at the radiator connections, and glow plug problems. The Allison transmission has a strong reputation. Ask whether the emissions system has been removed ("deleted"), which can cause inspection and legal problems.
Other things to check
- Cracked dashboard, especially around the passenger airbag and gauges
- Trucks with an auxiliary battery were recalled for a fusible link that can melt (recall 14V407000)
- Rust on rocker panels, cab corners, wheel arches, frame and brake lines
Before you buy
- Check open recalls at nhtsa.gov/recalls with the VIN, especially the airbag recalls.
- Get a pre-purchase inspection that includes the steering linkage.
- Bring our used truck inspection checklist.

Common failures & how to fix them
Parts and video buttons search for your 2007 GMC Sierra 3500HD. Always confirm a part fits using your VIN. Brakes, steering, fuel and airbag work affects your safety, so if you're not sure, have a qualified mechanic do it.
Worn idler arm and pitman arm
Moderate DIYSigns: Loose, wandering steering, clunks, play in the steering wheel.
Fix: Replace the idler arm and pitman arm, and check tie rods. Many owners add an idler arm support brace. Get an alignment afterward.
Passenger airbag inflator recall
Dealer (recall)Signs: No warning. The inflator can rupture in a crash.
Fix: Covered by GM recalls. A dealer replaces the airbag for free.
May be covered free by recall 15V324000 / 20V011000. Check the VIN at nhtsa.gov/recalls.
Transmission cooler line leaks (diesel)
Moderate DIYSigns: Transmission fluid dripping near the radiator, low fluid.
Fix: Replace the cooler lines, usually where the rubber hose meets the metal crimp.
Cracked dashboard
Easy DIYSigns: Cracks across the dash top, especially near the passenger airbag.
Fix: Cover it with a molded dash cover or replace the dash pad. Make sure a cover doesn't block the airbag.
Rusted brake lines
Hard DIYSigns: Heavy scale or swelling on the steel lines along the frame, a soft pedal, or a fluid leak.
Fix: Replace rusted lines with pre-bent lines or copper-nickel line, then bleed the brakes. Do the whole run, not just the bad spot.

A recall doesn't mean a truck still has the problem. Enter the truck's VIN at nhtsa.gov/recalls or ask a dealer to see whether the repair was done.
Air Bags:Frontal:Passenger Side:Inflator Module
Jan 2020 · #20V011000General Motors LLC (GM) is recalling certain 2007-2008 Chevrolet Silverado 2500 and 3500 and GMC Sierra 2500 and 3500 vehicles equipped with non-desiccated, passenger frontal air bag inflators containing phase stabilized ammonium nitrate (PSAN) propellant that were used as interim remedy parts for previous Takata recalls. These inflators may explode due to propellant degradation occurring after long-term exposure to high absolute humidity, high temperatures, and high temperature cycling.
Risk and fix
Risk: An inflator explosion may result in sharp metal fragments striking the front passenger or other occupants resulting in serious injury or death.
Fix: GM will notify owners, and dealers will replace the front passenger air bag inflators, free of charge. The recall began February 11, 2020. Owners may contact Chevrolet customer service at 1-800-222-1020 or GMC customer service at 1-866-522-9559. GM's number for this recall is N192290990.
Air Bags:Frontal:Passenger Side:Inflator Module
May 2015 · #15V324000General Motors LLC (GM) is recalling certain model year 2007-2008 Chevrolet Silverado 2500HD and 3500HD trucks manufactured November 28, 2006, to August 29, 2008, and 2007-2008 GMC Sierra 2500HD and 3500HD trucks manufactured November 27, 2006, to August 29, 2008. The affected vehicles are equipped with a passenger side frontal air bag that may be susceptible to moisture intrusion which, over time, could cause the inflator to rupture upon its deployment.
Risk and fix
Risk: In the event of a crash necessitating deployment of the passenger's frontal air bag, the inflator could rupture with metal fragments striking the vehicle occupants, potentially resulting in serious injury or death.
Fix: GM will notify owners, and dealers will replace the front passenger air bag inflator, free of charge. The recall began on July 27, 2015. Owners may contact Chevrolet customer service at 1-800-222-1020 or GMC customer service at 1-800-462-8782. GM's numbers for this recall are 15438 and 15817.
Electrical System
Jul 2014 · #14V407000General Motors LLC (GM) is recalling certain model year 2007-2011 Chevrolet Silverado HD 2500/3500 trucks manufactured January 18, 2007, to June 22, 2011, and GMC Sierra HD 2500/3500 trucks manufactured January 22, 2007, to June 21, 2011, and equipped with an auxiliary battery. Owners may unknowingly draw too much current through the vehicle's trailer harness resulting in the melting of fusible link for the auxiliary battery.
Risk and fix
Risk: If the fusible link melts it may come into contact with adjacent components, damage the electrical center cover, the nearby wiring harness conduit and other vehicle components, increasing the risk of a fire.
Fix: GM will notify owners and dealers will replace the jumper harness with one that includes a 40 amp inline fuse, and provide the owner with supplemental Owner Manual information, free of charge. The recall began on August 29, 2014. Owners may contact Chevrolet customer service at 1-800-222-1020 or GMC customer service at 1-800-462-8782. GM's number for this recall is 14260.

Safety ratings
NHTSA 5-Star Safety Ratings from government crash tests. Ratings can differ by cab style and 2WD/4WD.
NHTSA hasn't published star ratings for this truck. Many heavy-duty pickups aren't included in NHTSA's crash-test program, so this doesn't mean the truck is unsafe.
