The 2017 CHEVROLET COLORADO is a versatile midsize pickup offered with a range of trims and three engine choices (including the base 2.5L inline‑4, a 3.6L V6, and the 2.8L Duramax turbo‑diesel). Whether you’re shopping for a work truck or a capable off‑roader (Z71 or the revived ZR2), this guide explains what to look for by trim and engine, key mechanical and history checks, a test‑drive checklist, and clear red flags so you don’t overpay.
Trim and Powertrain Overview — what matters
- Work Truck (WT): Basic, inexpensive, often used as fleet units. Expect simpler interiors and more wear. Look for service records and bed condition.
- LT: Common midgrade trim with convenience options and nicer infotainment. Check added option packages (trailering, convenience, tech).
- Z71: Off‑road package with tuned suspension, skid plates, and upgraded tires — good for light off‑road use. Inspect underbody and suspension components.
- ZR2 (2017 reintroduced): Heavy‑duty off‑road model with wider track and unique suspension hardware. Check for specific ZR2 components and any off‑road damage.
- High Country / top trims: Leather, advanced features, more electronics to validate (heated seats, cameras, sensors).
Engine-specific considerations
- 2.5L inline‑4 (base): Simple and economical for light tasks. Inspect for oil leaks, coolant condition, and ensure it has acceptable performance for highway passing — it’s not as quick as the V6 or diesel.
- 3.6L V6: The middle ground for power and towing. Verify smooth idle and acceleration; listen for unusual valvetrain noise and watch for oil consumption or leaks.
- 2.8L Duramax diesel: Best for fuel economy and towing. Important to check for proper turbo operation, smoke on acceleration, injector noises, and a clean service history (diesels do not tolerate neglect well).
Key mechanical and history checks
Before you buy, gather documentation and perform targeted inspections:
- VIN and title check: Use Carfax, AutoCheck or similar to verify accident and salvage history, odometer events, and service entries.
- Recalls and TSBs: Check NHTSA and GM owner centers for open recalls and technical service bulletins for the model year and VIN — always ask for proof of repairs if there were recalls.
- Service records: Regular oil changes, timely diesel maintenance (fuel filter, particulate system if equipped), and transmission service are big positives.
- Rust and frame/underbody: Inspect frame rails, suspension mounts, bed floor, tailgate, and wheel wells. Look for welding repairs, heavy corrosion, or replaced structural parts.
- 4WD/transfer case: For 4×4 models, test engagement in both high and low range and listen for grind or clunking. Check front differential seals.
- Aftermarket mods: Tuners, lifts, oversized tires, and modified exhausts affect handling, emissions, and reliability—ask about who did the work and why.
Test‑drive checklist
Plan a 15–30 minute drive that includes city streets and a highway section:
- Cold start: On startup, listen for odd noises, excessive cranking, or white/blue smoke. Let the engine idle and note roughness or stalling.
- Acceleration and passing: Check for smooth, consistent power delivery and no hesitation. Diesels should accelerate without black smoke or loud surges.
- Transmission: Shifts should be smooth and timely with no slipping, hunting, or harsh engagement. Automatic delays or hard shifts are warning signs.
- Brakes and steering: Test for straight braking, no pulsing (warped rotors), and steering that is not loose or noisy. Check for wandering or vibrations at speed.
- Suspension and noises: Drive over bumps to listen for clunks, knocks, or rattles; for Z71/ZR2 verify specialized hardware feels firm and functional.
- HVAC and electronics: Test A/C and heat, infotainment, cameras, sensors, cruise control, and power accessories.
- Idle and exhaust: Note unusual exhaust smell inside the cabin or signs of coolant/oil burning.
Red flags before you pay
- Check engine light, ABS light, or airbag lights on at sale — verify reasons and request documentation of repairs.
- Mismatched paint panels, inconsistent gap tolerances, or fresh welds that suggest structural repairs after a significant collision.
- Severe rust on frame rails, suspension mounts, or bed — structural rust can be expensive or dangerous.
- Hard shifting, slipping, loud transmission or differential noises — costly to fix, especially if no history of service.
- Excessive oil consumption, persistent leaks, or white smoke (coolant burning) from the exhaust.
- Evidence of flood damage — musty smells, corrosion under carpets, water stains, or electrical gremlins.
- Unexplained aftermarket engine tuners or cheat devices — they can mask issues and reduce longevity.
Negotiation tips
Factor in needed maintenance (brakes, tires, fluids), pending recall repairs, and any visible damage. Use independent inspection quotes and a pre‑purchase inspection from a trusted mechanic (especially for diesel and ZR2 variants) to strengthen your negotiating position.
Final thoughts
The 2017 CHEVROLET Colorado can be an excellent midsize truck whether you want an economical 2.5L work truck, a balanced V6 cruiser, or the torque and efficiency of the 2.8L Duramax. The keys to a smart purchase are verifying the vehicle’s history and recall status, performing a focused mechanical inspection (or paying for a pre‑purchase inspection), and using a thorough test drive to reveal transmission, engine, suspension, and electronic issues. Pay extra attention to rust, off‑road wear on Z71/ZR2 models, and any signs of aftermarket tuning. If it checks out, the Colorado offers a compelling combination of capability and manageable ownership costs.
FAQs
- Q: Is the 2.5L engine reliable for daily use and towing?
- A: The 2.5L is reliable for daily driving and light towing but has less power than the V6 or diesel — if you plan regular towing or heavy loads, prioritize the V6 or Duramax.
- Q: Are there common transmission problems with the 2017 Colorado?
- A: Any used Colorado should be checked for smooth shifting and no slipping or harsh engagement. Confirm service history; abnormal shifting or noises warrant further inspection.
- Q: Should I avoid ZR2/Z71 models because of off‑road wear?
- A: Not necessarily—off‑road trims are desirable for capability, but they can be harder used. Inspect for underbody damage, suspension wear, and the integrity of skid plates and control arms.
- Q: How important is a diesel service history?
- A: Very important. Diesel engines depend on timely maintenance (fuel filters, oil changes, turbo care). Lack of documented maintenance reduces resale and increases repair risk.
- Q: Is a pre‑purchase inspection necessary?
- A: Yes. A qualified mechanic can identify hidden problems and give you leverage in price negotiations. This is especially valuable for diesel and high‑trim or off‑road models.
