Used Chevy Colorado Buying Guide

Updated September 2026 by MN, Savvy Dealer Inc.

Since replacing the S10 in 2004, the Chevy Colorado has lived three very different lives. It started as a compact joint venture with Isuzu, evolved into a class-leading midsize hauler, and has now transformed into a high-torque, tech-heavy beast. Buying a used Colorado requires knowing exactly which version you're getting, as mechanical pitfalls and capabilities shift dramatically between generations. We'll break down the details here, so you know what to look for when buying a used Chevy Colorado

Key Takeaways

Used Chevrolet Colorado First Generation

To avoid the 8-speed "shudder" in 2015 to 2019 models, verify that a mechanic serviced the transmission. If you can't, stick to 2020 and newer models to avoid well-documented shifting failures.
The Colorado's second-gen 2.8L Duramax is the only choice for long-distance towing efficiency; the new 2023+ engines have the torque but can't match the diesel's 31 mpg.
If you need a long bed or a regular cab, stop looking at the 2023+ models. They only come with a short bed crew cab.

The Compact Original Colorado (2004-2012)

Used Chevrolet Colorado Second Generation

If you want a truck that's actually small, the first-gen Colorado should be your pick. It's available in regular, extended, and crew cabs, making it the most flexible for tight garages and parking spots. This era featured unique inline-four and inline-five engines.

But a word of warning--pre-2007 models are known for soft valve seats that lead to expensive cylinder head repairs. (The 2007 facelift brought updated 2.9-liter and 3.7-liter engines that resolved many of these issues.) While these trucks are vulnerable to rust, they remain an affordable entry point.

The Colorado's Versatile Sweet Spot (2015-2022)

Used Chevrolet colorado Third Generation

After a short hiatus, the Colorado returned in 2015. This second generation is the most flexible for buyers, offering a 2.5-liter four-cylinder, a 3.6-liter V6, and the rare 2.8-liter Duramax diesel. That diesel is a gem for towing, providing a class-leading 7,700-pound capacity and up to 31 mpg on the highway.

Reliability is the main concern here. Models built between 2014 and 2019 had 8-speed transmission "shudders" and rough shifts. If you're shopping in this window, prioritize trucks with documented transmission fluid flushes or look for 2020 and newer models. Unlike the newest generation, you can still find these with an extended cab and a 74-inch long bed, which is a must if you actually plan on hauling 4x8 plywood.

The Colorado as a High-Tech Powerhouse (2023-Present)

Chevy built the third-generation Colorado on a wider frame, and it almost feels full-size. With a standard 11.3-inch touchscreen, Google Built-In, and sharp digital displays, the cabin's tech is more modern.

The automaker replaced the V6 and the turbodiesel with 2.7-liter turbocharged four-cylinder engines shared with the Silverado.

While the cylinder count is down, the TurboMax versions deliver up to 430 pound-feet of torque. If you're looking for value, the Trail Boss is the standout, offering a factory lift and off-road chops without the premium price of the top-tier ZR2. However, keep in mind that there are no extended cabs or long beds available (it's crew cab only).

Which Colorado Generation Should You Consider?

If you want the best truck in this lineup, skip the early first-gens and the "shuddering" early second-gens. The 2020-2022 V6 model is best for a balance of reliability and utility. Stop by our Car2Sell Hillside showroom today to see what we have in stock!
