2019 Chevrolet Colorado Reviews – The Essential Guide For Owners
The 2019 Chevrolet Colorado stands as a versatile midsize pickup that balances daily drivability with genuine workhorse capabilities. This guide explores real-world performance, common mechanical pitfalls like transmission shudder, and maintenance tips to help you maximize your truck’s lifespan.
Finding a truck that fits into a standard garage while still hauling a heavy trailer is a common challenge for many enthusiasts. You want the utility of a bed without the massive footprint of a full-size rig, and the Colorado often fits that bill perfectly.
In this deep dive into 2019 chevrolet colorado reviews, I will break down the powertrain options, common DIY fixes, and off-road configurations. Whether you are looking at a used Z71 or maintaining a high-mileage Work Truck, these insights will keep you on the road or trail.
We will cover everything from the LGZ 3.6L V6 engine quirks to the specialized suspension of the ZR2. By the end of this article, you will have a professional technician’s perspective on what makes this truck tick and how to avoid costly repairs.
Understanding the Powertrain: V6 vs. Duramax Diesel
The 2019 model year offered three distinct engines, but most buyers focused on the 3.6L V6 and the 2.8L Turbo-Diesel. Each has a specific personality and maintenance schedule that every owner should understand before diving into the engine bay.
The LGZ 3.6L V6 engine is the most common choice, delivering a healthy 308 horsepower. It utilizes variable valve timing solenoid technology to balance power and efficiency, though these solenoids can sometimes clog if oil changes are neglected. Always use a high-quality Dexos 1 Gen 2 motor oil to keep these sensitive components moving freely.
For those focused on towing or long-distance fuel economy, the LWN 2.8L Duramax Turbo-Diesel is a gem. It provides massive low-end torque, making it feel much larger than a midsize truck when pulling a trailer. However, diesel owners must stay vigilant about the EGR cooler assembly and DEF fluid levels to avoid “limp mode” scenarios.
If you are looking for specific output data, checking the Colorado technical specifications can help you decide which engine fits your payload requirements. Both engines are capable, but they require different approaches to long-term care.
2019 chevrolet colorado reviews: Reliability and Common Issues
When analyzing 2019 chevrolet colorado reviews from long-term owners, a few recurring themes emerge regarding reliability. While the truck is generally robust, the 8-speed transmission and specific electronic sensors are known “hot spots” for DIYers to watch.
The 8L45 8-speed automatic transmission is perhaps the most discussed component in owner forums. Many drivers report a “shudder” or vibration at cruising speeds, often feeling like they are driving over rumble strips. This is frequently caused by moisture absorption in the transmission fluid, which leads to torque converter clutch slip.
Diagnostic trouble codes like the P0700 transmission control system malfunction often accompany these shifting issues. In many cases, a full fluid flush with the updated Mobil 1 Synthetic LV ATF HP fluid resolves the problem. If you encounter this, address it early to prevent permanent damage to the torque converter.
Beyond the gearbox, some owners report issues with the mass air flow sensor or the transfer case encoder motor on 4WD models. These are relatively straightforward DIY fixes that do not require specialized heavy machinery, making the Colorado a friendly platform for weekend mechanics. You can find more details on known engine issues to stay ahead of potential breakdowns.
The Diesel Emissions System
The Duramax diesel variant brings its own set of unique challenges, primarily centered around the emissions hardware. The DEF fluid heater and the EGR cooler assembly are common failure points that can trigger a check engine light.
If you notice a drop in fuel economy or a “Service Exhaust System” message, the EGR system is likely the culprit. Cleaning the EGR valve is a possible DIY task, but often the cooler itself becomes restricted by soot over time, requiring a more involved replacement.
Unique Value: 2019 Colorado Symptom-to-Cause Matrix
To help you diagnose issues quickly, I have compiled this table based on common owner reports and technician observations.
| Symptom | Common Cause | Recommended Action |
|---|---|---|
| Vibration at 45-65 MPH | Transmission Fluid Breakdown | Flush with Mobil 1 Synthetic LV ATF HP |
| Rough Idle / Stalling | Dirty Mass Air Flow Sensor | Clean with MAF-specific spray cleaner |
| “Service 4WD” Message | Transfer Case Encoder Motor | Inspect wiring harness or replace motor |
| Slow Cranking in Cold | DEF Fluid Heater Failure | Test heater resistance; replace if open circuit |
| Ticking Noise from Engine | VVT Solenoid Wear | Check oil level; replace solenoids if needed |
Off-Road Performance: The ZR2 Advantage
The 2019 Colorado ZR2 is frequently cited in 2019 chevrolet colorado reviews as the gold standard for midsize off-roading. Unlike the standard Z71, the ZR2 features a wider track, functional rock sliders, and the legendary Multimatic DSSV dampers.
These dampers use spool-valve technology rather than traditional pistons and shims. This provides incredible control when landing jumps or crawling over jagged rocks, yet maintains a smooth ride on the highway. If you are an off-roader, these shocks are worth the premium, but remember they are not rebuildable like some aftermarket options.
The ZR2 also includes front and rear electronic locking differentials. This is a rare feature in the midsize segment, allowing the truck to maintain traction in extreme “cross-axle” situations where one wheel is off the ground. When using these lockers, always engage them on loose surfaces to avoid binding the drivetrain.
For those planning an 2.8L Duramax maintenance schedule on a ZR2, keep in mind that off-road use accelerates wear on air filters and suspension bushings. Regularly inspect your CV boots for tears after a weekend on the trails, as a torn boot will quickly lead to a ruined axle.
DIY Maintenance: Keeping Your Colorado Healthy
One of the best things about the 2019 Colorado is the ease of performing basic maintenance. Most components are easily accessible, and the truck’s height allows for oil changes without necessarily needing a jack or ramps.
Oil and Filter Changes
The oil filter on the 3.6L V6 is a cartridge style located on top of the engine, which makes for a mess-free change. For the diesel, the filter is a standard spin-on type. Always ensure you lubricate the O-ring on the filter housing to prevent leaks under high pressure.
Using the correct fluid is non-negotiable. For the V6, stick to Dexos 1 Gen 2 specifications. This oil is formulated to prevent low-speed pre-ignition (LSPI), which can be an issue in modern direct-injected engines. Keeping your oil fresh is the best way to protect the variable valve timing solenoid units from sludge buildup.
Air Filter and Cabin Filter
Don’t overlook the engine air filter, especially if you drive on dusty roads. A clogged filter will sap your power and significantly impact your fuel economy. The cabin air filter is located behind the glovebox and should be swapped every 15,000 miles to keep the HVAC system smelling fresh and blowing strong.
Towing and Payload Realities
While the Colorado is a “midsize” truck, its towing numbers are quite impressive. When properly equipped with the V6 and the trailering package, it can tow up to 7,000 pounds. The diesel pushes that number even higher to 7,700 pounds.
However, many 2019 chevrolet colorado reviews point out that “towing capacity” is only half the story. You must also account for payload capacity—the weight of passengers, gear in the bed, and the tongue weight of the trailer. Overloading the rear axle can lead to “squat,” which compromises steering and braking safety.
If you plan on heavy hauling, consider adding a weight-distribution hitch. This helps level the truck and trailer, providing a much more stable experience at highway speeds. Always check your tire pressures before a big tow, as the rear tires will be under significantly more stress than during empty commuting.
Buying Advice: What to Look for in a Used 2019 Colorado
If you are in the market for a used 2019 Colorado, your primary focus should be the service history of the transmission. Ask the seller if the transmission fluid flush has been performed. If the truck still has the original “factory fill” fluid and has more than 30,000 miles, factor the cost of a flush into your offer.
Check the frame for excessive rust, especially near the rear leaf spring mounts. While Chevy has improved their corrosion resistance, trucks from the “salt belt” can still show premature wear. Also, test the 4WD engagement while on a gravel or dirt surface to ensure the transfer case encoder motor shifts smoothly between 2WD, 4-Auto, and 4-Low.
Finally, inspect the interior electronics. The Chevrolet Infotainment 3 system is generally reliable, but ensure the touchscreen is responsive and that both Apple CarPlay and Android Auto connect without dropping out. These small details can be expensive to fix if the head unit is failing.
Frequently Asked Questions About 2019 chevrolet colorado reviews
Is the 2019 Chevrolet Colorado a reliable truck?
