Chevrolet Colorado Technical Service Bulletins Guide
Technical Service Bulletins are your insider track to known Colorado issues—and knowing about them can save you time, money, and frustration.
You know that feeling when something doesn’t seem quite right with your Colorado, but the dealership says “we couldn’t reproduce the issue”? Sometimes the problem is already documented, and your technician just needs the right bulletin number. Here’s the thing about TSBs—they’re not recalls, but they’re the next best thing. They tell you what’s known, what’s been fixed, and how to get it sorted.
What Is a Technical Service Bulletin?
A TSB is an official communication from Chevrolet to its dealership service departments. It describes a known problem, provides step-by-step diagnostic procedures, and gives the exact repair instructions. Think of it as a cheat sheet for your mechanic.
The key difference from recalls: Recalls address safety defects and are always free. TSBs address common issues that aren’t necessarily safety-critical—but if your Colorado is still under warranty, the repair is often covered .
Colorado TSB Counts by Year
The Colorado has been assigned hundreds of TSBs across all model years. The 2022 model year alone has 663 technical service bulletins on file . This number can vary significantly by model year, with some years seeing far more documentation than others.
Major Documented Colorado Issues
1. Vibration at Idle (2015–2021)
On rare occasions, owners of 2015–2021 Colorado trucks may experience a vibration at idle in gear or at very low speeds .
The cause: A stray nut or debris (rock, etc.) wedged between the rubber and metal portions of the transmission mount .
The fix: Loosen the mount fasteners, manipulate the mount to allow removal of the foreign object, and torque all fasteners to specification .
2. IPC and Radio Blank Screen (2023)
For the 2023 Colorado, owners may experience a blank instrument panel display, no audio, or a “Failed Update” message after a discharged battery event .
The cause: Logic lock-up, usually due to low voltage or a failed update .
The fix: Disconnect the battery for 15 minutes and reconnect. If function returns, perform a battery test and check for available radio software updates .
3. Transmission DTCs from Loose Connections (2023–2024)
For 2023–2024 Colorado models, the Check Engine Light may illuminate with one or more transmission-related DTCs .
The cause: Poor terminal connections at the transmission connector (X175) .
The fix: Inspect the transmission connector, verify all terminals are properly seated, and check proper terminal tension. Repair or replace terminals as needed .
4. Engine Misfire and Check Engine Light (2004–2005)
For 2004–2005 Colorado models with 2.8L inline 4-cylinder or 3.5L inline 5-cylinder engines, owners may experience a Check Engine Light with misfire DTC P0300 .
The cause: Faulty exhaust valve springs and seals on engines built before VIN breakpoint 58261313 and build date 04/13/2005 .
The fix: Replace all exhaust valve springs and seals. This requires removing the intake and exhaust camshafts .
5. 2024 Recall: Incorrect Tires (NHTSA 24V-366)
This is a recall, not a TSB—meaning it’s safety-related and must be fixed for free.
Affected vehicles: 2024 Chevrolet Colorado Z71 and Trail Boss trim lines ordered with 20″ tires with black wheels (LPO SNX) .
The problem: Incorrect tires may have been installed that don’t match the vehicle’s tire label. The tire pressure monitoring system (TPMS) also doesn’t provide accurate information for the incorrect tires .
The fix: Dealers will inspect tires and replace if necessary . Only 56 vehicles are affected .
