Best Chevrolet Colorado Model Years (Ranked)

The Chevrolet Colorado is one of the most capable and versatile mid-size pickups on the market, offering everything from an efficient turbodiesel to the off-road-ready ZR2 and the high-performance ZR2 Bison. But across its two main modern generations the Colorado has varied in reliability, with certain early model years carrying known defects and others standing out as genuinely dependable trucks.

Choosing the right year matters whether you want a daily-driver work truck, a fuel-sipping diesel, or a trail-ready off-roader. This ranking sorts the best Chevrolet Colorado model years by engine reliability, capability, known problems, and used-market value.

We weighed the engines (the 2.5L four, the 3.6L V6, the excellent 2.8L Duramax diesel, and the new 2.7L turbo), transmission behavior, the major differences between the second generation (2015-2022) and the all-new third generation (2023+), recall history, and current used pricing.

The result is a clear guide to which Colorado to buy and which years to approach with care.

Direct Answer

The best overall Chevrolet Colorado model year is the 2021, a late second-generation truck. By 2021 Chevrolet had refined the second-gen platform, the 3.6L V6 (308 hp) and 2.8L Duramax diesel (181 hp, 369 lb-ft) were proven, the 8-speed automatic behind the V6 was sorted, and the ZR2 off-road package was at its best.

It combines maturity, capability, and strong used value.

The best value Chevrolet Colorado is the 2018-2019, mid-cycle second-generation trucks. These benefit from accumulated fixes to the early second-gen issues, offer the full engine lineup including the efficient diesel, and have depreciated into affordable territory. The diesel is the standout for high-mileage drivers.

Avoid the troubled first-year 2015 trucks if you can.

1. 2021 Colorado (2nd Gen) 🏆 BEST OVERALL

The 2021 is the most refined second-generation Colorado. The 3.6L V6 makes 308 hp and 275 lb-ft with the smooth 8-speed automatic, and the 2.8L Duramax diesel delivers up to 30 mpg highway and a 7,700-lb tow rating, exceptional for a mid-size truck. By 2021 the early platform bugs were resolved, infotainment and safety tech were modern, and the ZR2 off-road model with its Multimatic spool-valve dampers and front and rear lockers was a genuine trail weapon.

The 2021 blends work-truck practicality, towing muscle, and off-road capability better than any other year. This is the most complete and dependable Colorado you can buy, with prices that have settled below new.

2. 2018-2019 Colorado (2nd Gen) 💎 BEST VALUE

The 2018-2019 trucks are the value sweet spot. They carry the full second-gen engine lineup, including the 2.8L Duramax diesel that returns up to 30 mpg highway, and they benefit from fixes to the earlier 8-speed transmission and electronics complaints. The ZR2 arrived in 2017 and was well-established by 2018.

Because they are several years old, the 2018-2019 Colorado offers the best balance of capability and low price, especially diesel-equipped examples. Verify the 8-speed automatic shifts cleanly without the early hard-shift behavior, and confirm the diesel's emissions system is healthy.

3. 2023 Colorado (3rd Gen, launch)

The 2023 launched the all-new third generation built entirely around a 2.7L turbo-four in three output levels, topping out at 310 hp and 430 lb-ft in the high-output tune. The new platform brought a modern interior, an 11.3-inch touchscreen, a wider track, and the impressive new ZR2 and ZR2 Bison off-road models.

It is genuinely more capable and refined than the second gen. It ranks here rather than at the top because it is a first-year truck with unproven long-term reliability and near-new pricing. For buyers who want the latest and most capable Colorado and accept launch-year risk, the 2023 is excellent.

4. 2020 Colorado (2nd Gen)

The 2020 is a strong late second-gen truck nearly identical to the 2021, with the proven 3.6L V6, the 2.8L Duramax diesel, and the capable ZR2. It shares the 2021's maturity at a slightly lower price, making it a smart value alternative. The diesel and V6 are both dependable when maintained, and the truck's ride and interior are pleasant for the class.

This is a dependable, sensible used buy that splits the difference between the bargain 2018-2019 and the most-refined 2021. Confirm clean transmission shifts and a healthy diesel emissions system before buying.

5. 2024 Colorado (3rd Gen)

The 2024 is the second year of the third generation, which means early-build bugs from the 2023 launch were addressed while the truck retains the modern 2.7L turbo lineup, the wide-track chassis, and the excellent ZR2 and ZR2 Bison off-road models. It is more proven than the 2023 but commands the highest used prices on this list.

Choose the 2024 if you want the newest, most capable Colorado with the longest warranty and don't need to maximize value. The single-engine 2.7L turbo strategy means no diesel or V6 option, which some buyers will miss.

6. 2017 Colorado (2nd Gen)

The 2017 introduced the ZR2 off-road model and refined the second-gen platform, with the 3.6L V6 upgraded to 308 hp and paired with the new 8-speed automatic. The 2.8L Duramax diesel was in its second year and well-regarded. The 2017 is a capable, affordable truck, sitting just below the 2018-2019 because the 8-speed automatic's early hard-shift complaints were most prevalent in this first year of that transmission.

A documented fluid service and a smooth test drive are important. For buyers who want an early ZR2 at a lower price, the 2017 is worth considering.

7. 2016 Colorado (2nd Gen)

The 2016 added the 2.8L Duramax diesel to the lineup for the first time, a major selling point, alongside the 3.6L V6 and 2.5L four. It improved on the 2015 launch with running fixes to early electronics and rattles. The diesel-equipped 2016 trucks are sought after for their efficiency and torque.

It ranks here because some early second-gen reliability quirks persisted, including infotainment glitches and minor build issues. A well-maintained 2016 diesel is a strong budget pick; verify the emissions system and transmission behavior carefully given the truck's age and the early-platform caveats.

8. 2022 Colorado (2nd Gen, final year)

The 2022 is the final year of the second generation, fully mature and well-sorted, with the proven 3.6L V6 and the capable ZR2. The diesel was dropped after 2021 in some markets, so V6 trucks dominate the 2022 used pool. It would rank higher on reliability, but as the last and newest second-gen year it commands higher prices while offering nothing mechanically new over the 2021.

Buy a 2022 if you want the newest pre-redesign Colorado with the longest warranty among second-gen trucks; otherwise the 2021 or 2020 deliver the same truck for less.

9. 2015 Colorado (2nd Gen, launch)

The 2015 relaunched the Colorado as an all-new mid-size truck and won acclaim for bringing a modern, refined pickup to the segment. However, as a first-year truck it carried the most launch bugs, including infotainment glitches, some transmission complaints, and early build-quality issues.

It offered only the 2.5L four and 3.6L V6 (no diesel until 2016). Prices are low, making it tempting, but the 2015 is best bought only with thorough documentation of repairs and updates. Later second-gen years fixed most of these issues, so the 2015 is the riskiest of the modern Colorados.

10. 2004-2012 Colorado (1st Gen)

The first-generation Colorado is the budget basement option. Built on the GMT355 platform, it offered 2.8L and 2.9L four-cylinders and a 3.5L/3.7L inline-five that were adequate but unremarkable, and an optional 5.3L V8 in later years. These trucks are cheap, simple, and have decent parts support, but the inline-five engines had head-gasket and reliability concerns and the interiors and ride feel dated.

Buy a first-gen Colorado only as an inexpensive basic work truck, ideally a well-maintained V8 or carefully inspected five-cylinder; it ranks last for its outdated engineering and weaker reliability record.

What to Watch For When Buying

The most common second-generation Colorado concern is the 8-speed automatic's hard-shift and shudder behavior, most prevalent in early 2017-2018 trucks; a fluid service often helps, so verify smooth shifts on the test drive. On the 2.8L Duramax diesel, confirm the emissions system (DPF and DEF) is functioning and free of fault codes, since diesel emissions repairs are costly.

First-year 2015 trucks had infotainment and build-quality bugs, so favor documented examples. On the new third-gen (2023+), watch for early-production software issues. On first-gen trucks, the inline-five head-gasket history is the key risk.

Across all years, run the VIN for open recalls and confirm on-time maintenance, especially on the diesel and turbo engines.

How to Choose

For the best overall truck, target a 2020-2021 second-gen Colorado with the 3.6L V6 or 2.8L diesel. For maximum value, a 2018-2019 diesel gives excellent economy and capability at a low price. If you want the newest, most capable Colorado and accept launch-year risk, the 2023-2024 third-gen with the 2.7L turbo is the most advanced.

Off-road buyers should seek a ZR2 or ZR2 Bison from any year. High-mileage drivers benefit most from the diesel, while buyers who value simplicity should choose the proven V6. As always, documented maintenance beats a cheaper, undocumented truck.

FAQ

What is the most reliable Colorado year? The 2020-2021 late second-generation trucks with the proven 3.6L V6 or 2.8L Duramax diesel are the most reliable, having shed the early-platform bugs and the early 8-speed transmission complaints.

Which Colorado years should I avoid? Be cautious with the 2015 launch year (infotainment and build bugs) and the early-build 2017 trucks with the 8-speed hard-shift issue. First-gen trucks (2004-2012) carry inline-five head-gasket risk.

Is the 2.8L Duramax diesel worth it? Yes for high-mileage drivers. It returns up to 30 mpg highway and tows 7,700 lbs, but the higher purchase price and diesel emissions maintenance only pay off if you drive a lot of highway miles.

How many miles will a Colorado last? A well-maintained second-gen Colorado can reach 200,000-250,000 miles, and the Duramax diesel often goes further. On-time service of the transmission and emissions system is the key to longevity.

Bottom Line

The 2021 Chevrolet Colorado is the best all-around buy, combining a proven V6 and diesel, modern tech, strong off-road options, and used prices below new. For the most truck per dollar, the 2018-2019 second-gen diesel is the value champion. Buyers wanting the newest, most capable truck should look at the 2023-2024 third gen.

Across every year, the priorities are the same: verify the 8-speed transmission shifts cleanly, confirm a healthy diesel emissions system, and buy the example with the best documented maintenance.
