2018 Chevrolet Colorado: True Cost of Ownership (5-Year Breakdown)
The 2018 Chevrolet Colorado is a mid-size pickup truck that strikes a balance between everyday practicality and work-ready capability, available in configurations ranging from base WT trims to the sporty ZL1-rivaling ZR2 off-roader. At around $20,500 on the used market, it appeals to buyers who want truck utility without full-size truck running costs. It's especially well-suited for contractors, outdoor enthusiasts, and families needing a versatile hauler on a tighter budget.
Monthly cost breakdown
The 2018 Colorado depreciates at a moderate pace for the mid-size truck segment — expect it to retain roughly 45-50% of its original MSRP after five years, which is respectable but trails segment leaders like the Toyota Tacoma that hold closer to 60%.
Pros
- Lower purchase price than a comparable full-size truck saves thousands upfront and reduces financing costs
- Fuel costs are meaningfully lower than a V8-powered full-size truck — the 3.6L V6 averages around 18 MPG combined keeping monthly fuel bills manageable
- Insurance premiums are moderate compared to full-size trucks or performance vehicles, averaging around $142/month for a typical driver
- Maintenance intervals and parts costs are reasonable, with routine services generally running $80–$150 at independent shops
Cons
- Fuel economy on the V6 model (17–24 MPG) lags behind rivals like the Honda Ridgeline and even the diesel Tacoma, adding up over 60,000 miles
- The 2.8L Duramax diesel option carries a purchase premium and higher maintenance costs that can erode its fuel savings over a 5-year window
- Depreciation is steeper than a Toyota Tacoma in the same segment, meaning resale value at year 5 is noticeably lower
- Reliability ratings from J.D. Power and Consumer Reports place the 2018 Colorado slightly below average for the mid-size truck segment, suggesting higher-than-ideal repair risk
Common problems to watch for
- Timing chain stretch on the 2.5L and 3.6L engines is a documented concern, particularly before 100,000 miles — listen for rattling on cold starts
- Transmission shudder or harsh shifting on the 8-speed automatic has been reported and sometimes requires a fluid flush or TCM software update
- Air conditioning compressor failures have been reported more frequently than the segment average, with repair costs typically $800–$1,200
- Excessive oil consumption on the 2.5L four-cylinder engine has prompted some owners to check levels more frequently between changes
- Infotainment MyLink system can freeze or lose connectivity with Apple CarPlay, often resolved via software update but occasionally requires head unit replacement
The verdict
The 2018 Chevrolet Colorado is a competent and affordable entry into mid-size truck ownership, but it's not the segment's value champion — that title still belongs to the Toyota Tacoma for buyers prioritizing resale and long-term reliability. At $20,500 with realistic all-in monthly costs around $612, it's a sensible pick if you find a well-maintained example with service records and no signs of the known timing chain or transmission issues. Buyers who do their due diligence and stick to V6 or diesel models with verified maintenance histories will get solid utility at a fair price.
Best for: The 2018 Colorado is the ideal buy for a value-conscious truck shopper who needs real towing and payload capability (up to 7,700 lbs towing on the V6) without paying full-size prices, and who plans to keep the truck 3–5 years before trading.

What trim of the 2018 Colorado is the best value to own?
