The 2000 GMC Sonoma has no open NHTSA recalls. Owners report 8 recurring issue clusters, led by “Tailgate support cable corrosion and breakage.” GMC trucks and SUVs use the GM Oil Life System (OLS) — the same algorithm as Chevrolet. Because GMC's lineup is exclusively trucks and SUVs, severe-service intervals apply to most owners (towing, hauling, off-roading). The schedule below surfaces the items most relevant to GMC's truck-focused buyer.
No open recalls on file. NHTSA lists no unrepaired safety recalls for this year, make and model. A recall can be issued at any time, and a specific car can still have one open — check yours by VIN at nhtsa.gov/recalls.

Critical for safety and preventing major damage
Change oil when OLS reaches 0% or every 12 months. dexos1-approved synthetic required on Sierra 1500 5.3L/6.2L; dexos2 specified on Duramax diesel.
Estimated cost — typical U.S. ranges
Dealer
~$120–$160
Shop
~$85–$115
DIY
~$25–$55
Full synthetic costs more than conventional. 5-quart 0W-20 + filter is the typical bill.
Rotate tires every 7,500 miles. Sierra and Yukon owners running 4x4 should rotate every 5,000-7,500 miles to even out drivetrain wear.
Estimated cost — typical U.S. ranges
Dealer
~$85
Shop
~$60
DIY
Free
Often free at the shop where you bought the tires — worth asking before paying.
Inspect pads, rotors, and parking brake every 7,500 miles. Towing accelerates pad wear by 30-50%; check more often if towing regularly.

Most shops do this free as a courtesy with any service. Don't pay separately if you can avoid it.
DOT 3 brake fluid: test annually, replace when moisture exceeds 3% or fluid is darker than copper.
Estimated cost — typical U.S. ranges
Dealer
~$180–$200
Shop
~$125–$140

DOT 3 or 4 — match the cap. Vacuum bleeders make this a one-person DIY.
Keeps your vehicle running smoothly and efficiently
Long-life cellulose filter rated 45,000 miles. Trucks driven on unpaved roads or construction sites should inspect at every oil change.
Estimated cost — typical U.S. ranges
Dealer
~$60–$95
Shop
~$45–$70
DIY
~$15–$40
5-minute job on most cars; the airbox lid usually has clips, no tools needed.
Severe service (towing 5,000+ lbs regularly, heavy stop-and-go): every 45,000 miles. Normal: 97,500 miles. Use Dexron-VI for 6L80/6L90, Mobil 1 LV ATF HP for 10L80/10L1000.

Dealer
~$330–$500

Some sealed transmissions have no dipstick — fill is precise and best left to a shop. Many drivers can still DIY drain-and-fill.
On 4WD models, replace every 45,000 miles. Use GM Auto-Trak II for active 4WD; GM 9986115 for selectable 4WD.
Estimated cost — typical U.S. ranges

Occupant deaths in fatal crashes (FARS)

177
occupant deaths
Crash years covered: 1990–2024 This model year first appears in 1999 crashes. Older models have had more years on the road to appear in these crashes, so a higher count here does not by itself mean a vehicle is less safe.
FARS counts every occupant death in a fatal crash, whatever the cause — it does not mean the vehicle was at fault or defective. Counts are not adjusted for how many of each vehicle are on the road. How to read this number
FARS 2024 data is an annual report file. NHTSA revises these records when the final file is published, so this count can change.
Every vehicle has exactly one driver seat, so driver deaths line up fairly when you compare one model to another. Occupant deaths include passengers, so a three row SUV can show a higher number than a two seat car simply because it carries more people.
Both figures are plain counts, not rates. A rate would need to know how many of each vehicle are on the road, and that registration data is not public, so we do not publish rates or scores of any kind.
IIHS publishes driver death rates using this same driver only idea, paired with a registered vehicle years denominator we do not have. Their rates and these counts answer different questions, so do not read either number here as a safety rating.
Owner-reported problem signals
Separate from the federal fatality data above: complaints owners filed with NHTSA about this year and model. These are reports of problems, unverified, and are counted here only as signals.
