This 2017 Chevrolet Colorado review explores the truck’s significant powertrain updates, including the refined V6 engine and the debut of the off-road-ready ZR2 trim. We provide essential insights into maintenance, common mechanical issues like transmission shudder, and real-world performance for DIYers and enthusiasts alike.
Finding a midsize truck that balances daily driveability with rugged capability is often a challenge for most owners. You likely want a vehicle that handles the morning commute with ease but can still haul a trailer to the campsite on Friday night. In this 2017 chevrolet colorado review, I will show you why this specific model year remains a top pick for used truck buyers.
We will dive deep into the technical updates that set the 2017 model apart from its predecessors, including the new 8-speed transmission and the updated V6. By the end of this guide, you will understand the common maintenance hurdles and the performance potential of this versatile pickup.
Whether you are looking for a reliable workhorse or a dedicated off-road machine, the 2017 Colorado offers a configuration for every need. Let’s look under the hood and see what makes this truck tick from a mechanic’s perspective.
Engine Performance and the New LGZ 3.6L V6 Engine
The 2017 model year brought a major heart transplant for the Colorado’s gasoline lineup. Chevrolet introduced the LGZ 3.6L V6 engine, which replaced the previous LFX version, offering better efficiency and slightly more power.
This engine utilizes Gasoline Direct Injection (GDI) and improved Variable Valve Timing (VVT) to deliver 308 horsepower. For the DIYer, this means the engine is more complex, requiring high-quality Dexos 1 Gen 2 synthetic oil to prevent carbon buildup on the intake valves.
If you notice a slight hesitation during acceleration, it could be related to the Variable Valve Timing solenoid. These solenoids control oil flow to the cam phasers and can become clogged if oil changes are neglected.
The LWN 2.8L Duramax Turbo-Diesel Option
For those who prioritize torque and fuel economy, the LWN 2.8L Duramax Turbo-Diesel is the star of the show. This engine provides 369 lb-ft of torque, making it a favorite for towing small campers or boats.
Owners should be aware of the Diesel Exhaust Fluid injector maintenance, as crystallized DEF can sometimes block the nozzle. Keeping the system clean ensures the truck stays out of “limp mode” during long highway hauls.
Reviewing the Colorado technical specifications shows that the diesel variant consistently leads the midsize class in cruising range. It is an excellent choice for long-distance adventurers.
Transmission Evolution: The 8L45 8-Speed Automatic Transmission
One of the most discussed features in any 2017 chevrolet colorado review is the introduction of the 8L45 8-speed automatic transmission. This gearbox was designed to keep the V6 engine in its power band more effectively than the older 6-speed units.
While the extra gears improve fuel economy, some owners have reported a “shudder” sensation at highway speeds. This is often caused by moisture absorption in the transmission fluid or a faulty torque converter clutch.
A common “pro” fix involves a full transmission fluid flush using the latest Mobil 1 Synthetic LV ATF HP fluid. If you are a DIY mechanic, checking the fluid level is tricky because there is no traditional dipstick; you must use the level-check plug on the transmission pan.
Transfer Case and 4WD Systems
The 4WD models feature a Transfer case control module that manages the transition between 2HI, 4HI, and 4LO. If you see a “Service 4WD” light on your dashboard, the culprit is often a corroded wiring harness or a faulty selector switch.
I recommend cycling through your 4WD modes at least once a month, even if you stay on the pavement. This keeps the internal actuator motor lubricated and prevents the internal gears from seizing up over time.
For those who frequently hit the dirt, the G80 automatic locking rear differential is a game-changer. It requires no driver input and locks automatically when it detects wheel slip, providing instant traction in mud or snow.
2017 chevrolet colorado review: Off-Road Prowess and the ZR2 Trim
The 2017 model year marked the birth of the ZR2, a truck designed to dominate technical trails right off the showroom floor. It features a wider track, functional rock sliders, and the legendary Multimatic DSSV spool-valve dampers.
In this 2017 chevrolet colorado review, it is impossible to ignore how the ZR2 changed the midsize market. It isn’t just a lift kit; it is a total re-engineering of the suspension geometry for high-speed desert running and rock crawling.
If you are buying a used ZR2, inspect the DSSV dampers for any signs of oil leakage. While they are incredibly durable, they are expensive to replace compared to standard twin-tube shocks found on the Z71 trim.
The Z71 hauling limits are slightly higher than the ZR2 due to the ZR2’s softer, off-road-tuned suspension. Always choose the trim that matches your primary use case, whether it is heavy towing or trail riding.
Towing and Payload Capabilities
When properly equipped with the V6 or Diesel engine and the trailering package, the Colorado can tow up to 7,000 or 7,700 pounds, respectively. This puts it at the top of its class for 2017.
Always use a weight-distribution hitch if you are approaching the maximum towing capacity. This ensures the front wheels maintain proper contact with the road, improving steering response and braking safety.
Check your Gasoline Direct Injection fuel pump performance if you notice a loss of power while towing uphill. A failing high-pressure pump may struggle to meet the increased fuel demand under heavy engine load.
Common Problems and DIY Troubleshooting
No 2017 chevrolet colorado review would be complete without addressing the common “gremlins” that owners might face. One frequent issue is the P050D Cold Start Rough Idle code, which often points to a fuel injector or carbon issue.
Because the 3.6L engine is a GDI design, fuel does not wash over the intake valves to clean them. Using an intake valve cleaner spray every 10,000 miles can prevent the stumbling and misfires associated with carbon buildup.
Electrical issues can sometimes stem from the battery cables or the mega-fuse located on top of the battery. Ensure these connections are tight and free of corrosion to avoid “ghost” warnings on the infotainment screen.
Diagnostic Symptom-to-Cause Matrix
To help you diagnose issues quickly, use this table as a starting point for your troubleshooting process.
| Symptom | Potential Cause | Recommended Action |
|---|---|---|
| Vibration at 45-65 MPH | Transmission Fluid Breakdown | Perform full ATF flush with Mobil 1 LV ATF HP. |
| Rough Idle on Cold Start | Carbon on Intake Valves (P050D) | Use GDI valve cleaner or inspect fuel injectors. |
| Clicking Noise when Turning | CV Axle Boot Failure | Inspect boots for tears; replace CV axle if clicking. |
| Loss of Power (Diesel) | Clogged DEF Injector | Clean or replace the DEF dosing valve. |
If you encounter Colorado engine issues that involve internal knocking or heavy oil consumption, consult a professional. These may require specialized tools like a borescope to inspect the cylinder walls properly.
Interior Comfort and Technology Integration
Inside the cabin, the 2017 Colorado feels more like a modern SUV than a traditional work truck. The MyLink infotainment system supports Apple CarPlay and Android Auto, which was a significant upgrade for the time.
The seats are supportive for long drives, though the rear legroom in the Crew Cab can be tight for taller adults. The use of soft-touch materials on the dashboard helps dampen road noise, making it one of the quietest rides in the midsize segment.
If your infotainment screen goes blank or freezes, try a hard reset by pulling the dedicated fuse in the passenger-side footwell. This often clears the software glitch without needing a dealership visit.
Maintenance Checklist for Longevity
To keep your truck running like new, a proactive maintenance schedule is essential. In this 2017 chevrolet colorado review, I emphasize that small investments in parts now prevent massive repair bills later.
- Oil Changes: Every 5,000 to 7,500 miles using Dexos-approved 5W-30 synthetic oil.
- Air Filter: Inspect every 15,000 miles, especially if you drive on dusty off-road trails.
- Coolant Flush: Every 100,000 miles to protect the aluminum engine components from corrosion.
- Brake Fluid: Test for moisture content every 2 years; flush if it exceeds 3%.
- Spark Plugs: Replace at 97,000 miles to maintain fuel efficiency and prevent misfires.
For those performing their own work, the oil filter on the 3.6L V6 is a cartridge style located on the top of the engine. This makes oil changes much cleaner compared to traditional spin-on filters hidden behind the wheel well.
Always use a torque wrench when tightening your lug nuts to 140 lb-ft. Over-tightening can warp the brake rotors, leading to a pulsating pedal during high-speed stops.
