2023 Chevrolet Colorado Review – Unpacking The Midsize Powerhouse

The 2023 Chevrolet Colorado marks a complete redesign, ditching the old V6 and diesel for a powerful, universal 2.7L turbocharged four-cylinder. This review explores how the new chassis, upgraded tech, and specialized off-road trims like the ZR2 redefine what a midsize pickup can handle on and off the pavement.

You’ve likely noticed that midsize trucks aren’t just “smaller Silverados” anymore; they are becoming specialized tools for adventure and work. If you are looking for a truck that balances garageability with serious grit, the 2023 Chevrolet Colorado is a top contender.

In this 2023 chevrolet colorado review, we will dive into the mechanical heart of this machine to see if the move to a single-engine lineup was the right call. We’ll cover everything from the new high-output powertrain to the long-term maintenance needs that DIY mechanics should know.

Whether you are upgrading from an older truck or buying your first pickup, understanding the shift in technology is crucial. Let’s get under the hood and see what makes this third-generation Colorado a game-changer for the segment.

The Heart of the Beast: 2.7L Turbo High-Output L3B Engine

The biggest news for 2023 is the standardized powertrain across all trims. Chevrolet decided to use the 2.7L Turbo High-Output L3B engine, a beast of a four-cylinder originally designed for the full-size Silverado.

This engine is not your average economy-car four-pot. It features a dual-volute turbocharger and a forged steel crankshaft to handle high boost levels. The direct fuel injection system ensures precise fuel delivery, though it requires high-quality fuel to prevent carbon buildup on the valves.

Depending on the trim you select, the output varies from 237 horsepower in the Work Truck (WT) to a massive 310 horsepower and 430 lb-ft of torque in the ZR2. This torque figure is higher than the outgoing V6 and matches the old Duramax diesel, providing excellent real-world hauling limits for those who tow trailers.

Engine Control Module Calibration

The different power outputs are achieved through engine control module calibration. While the physical hardware of the engine is largely the same in the “Turbo Plus” and “Turbo High-Output” versions, the software dictates the boost levels and timing.

For DIYers, this means the potential for future tuning is high. However, keep in mind that the high-output versions utilize a variable displacement oil pump that is specifically tuned for the increased heat generated by higher boost pressures.

Driving Dynamics and the 8L80 8-Speed Automatic Transmission

Power is sent to the wheels via the second-generation 8L80 8-speed automatic transmission. Chevrolet has refined the shifting logic in this unit to reduce the “hunting” for gears that plagued some previous midsize trucks.

The transmission features a wide gear ratio spread, allowing for a low first gear to get heavy loads moving and a tall top gear for highway efficiency. During my time behind the wheel, the shifts felt crisp and predictable, especially when using the tow/haul mode.

If you are an off-roader, you will appreciate how the transmission interacts with the transfer case. The transfer case fluid specification is vital here; using anything other than the recommended Dexron fluid can lead to shuddering during 4WD engagement.

2023 chevrolet colorado review

When evaluating the 2023 chevrolet colorado review from a practical ownership perspective, the chassis redesign is the unsung hero. The wheelbase has been stretched by 3.1 inches, moving the front wheels forward to improve the approach angle for off-roading.

The interior has finally moved into the modern era. Every model comes with an 11.3-inch diagonal infotainment screen that features Google built-in. This system is fast and intuitive, though it does move the headlight controls into the screen, which is a point of contention for some traditionalists.

From a reliability standpoint, the truck feels robust. However, as an expert who keeps an eye on common engine issues, I recommend monitoring the turbocharger wastegate actuator. In some early units, these have shown signs of premature wear, leading to boost fluctuation.

Off-Road Dominance: Multimatic DSSV and Locking Differentials

For the off-road enthusiast, the 2023 Colorado offers the most capable factory midsize truck on the market. The ZR2 trim is the crown jewel, featuring Multimatic DSSV dampers that use spool-valve technology to provide exceptional control on high-speed desert runs and low-speed rock crawling.

The ZR2 also features an electronic locking front differential and a rear locker. This setup allows you to maintain traction in the most technical terrain. Even the entry-level Trail Boss trim comes with a 2-inch factory lift and a wider track, making it a great platform for further modifications.

• Baja Mode: Optimizes throttle response and shift points for high-speed sand driving.
• Terrain Mode: Enables one-pedal driving for technical rock crawling, automatically applying brakes when you lift off the gas.
• Off-Road Mode: A balanced setting for general trail riding and dirt roads.

If you plan on taking your Colorado deep into the backcountry, ensure you carry a portable jump starter and basic recovery gear. The electronic systems in these modern trucks are sensitive to voltage drops, so keeping your battery in top shape is mandatory.

Maintenance and DIY Serviceability

For the weekend mechanic, the 2023 Colorado is relatively straightforward to maintain, provided you have the right tools. The engine bay is a bit tighter due to the turbocharger plumbing, but basic service points are accessible.

Oil changes are critical for turbocharged engines. You must use Dexos1 Gen 3 synthetic motor oil to protect the turbo bearings and prevent low-speed pre-ignition (LSPI). The oil change interval is monitored by the truck’s computer, but I recommend a 5,000-mile interval if you tow or off-road frequently.

When performing your first service, locating the oil filter is the first step. It is a cartridge-style filter located on the top of the engine, which makes for a mess-free change compared to old spin-on filters. Just be careful not to over-tighten the plastic housing cap.

Recommended Maintenance Schedule

1. Every 7,500 Miles: Rotate tires, check brake pads, and change oil/filter.
2. Every 22,500 Miles: Replace the passenger compartment air filter.
3. Every 45,000 Miles: Replace the engine air cleaner filter and change the transfer case fluid.
4. Every 97,500 Miles: Replace spark plugs (turbo engines are hard on plugs).

Unique Value: Turbocharged Engine Diagnostic Table

If you notice your Colorado isn’t performing quite right, use this table to narrow down potential causes before heading to the dealership.

Symptom	Potential Cause	Action Step
Whistling or Hissing under load	Boost leak or loose intercooler pipe	Inspect all clamps and rubber hoses for tears.
Lack of power / “Limp Mode”	Turbocharger wastegate actuator failure	Scan for P0234 or P0299 codes.
Blue smoke from exhaust	Turbocharger seal failure	Check intake tract for excessive oil pooling.
Rough idle / Hesitation	Carbon buildup on intake valves	Use a high-quality intake valve cleaner spray.

Troubleshooting Common Concerns

While the 2023 Colorado is a huge step forward, no vehicle is without its quirks. One common complaint in this 2023 chevrolet colorado review cycle involves the battery draining if the infotainment system doesn’t shut down properly after the truck is turned off.

If you experience a dead battery, check for software updates at your local dealer. Chevrolet has released several over-the-air (OTA) updates to address parasitic draws. Additionally, keep an eye on the cooling system; the 2.7L engine runs hot by design, so any coolant smell should be investigated immediately.

For those who live in colder climates, the direct injection system can be noisy upon startup. This “clicking” sound is normal operation for the high-pressure fuel injectors and the variable displacement oil pump, but if the sound persists after the engine is warm, have a professional look at it.
