When does it fail?
Of the 13 engine complaints filed for the 2007 Chevrolet Colorado, here's the actual mileage breakdown — failures cluster heaviest at 25,000-50,000 mi.
Each bar shows the share of total complaints filed at that mileage range. Peak failure window highlighted. Some owners report problems earlier; some make it well past 150,000 miles symptom-free. Maintenance habits and driving conditions shift the curve as much as mileage alone.
No new NHTSA engine complaint has been filed on this vehicle in over 18 years — the issue may be aging out of the active population.
Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering engine on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
This bulletin provides information on identifying Non-GM Engine Calibrations for Gasoline Engines using the Tech 2 or GDS 2.

The failure pattern owners describe
Owners report four distinct engine problems on 2007 Colorados. Valve failures appear as burnt valves or failed seats causing compression loss and rough running. One owner faced a $2,800 repair at 75,000 miles; Chevy paid only half despite knowing 2005-2006 models had service bulletins for identical issues. Another owner's independent shop found a cylinder #4 valve broken in two places.
Stalling and shutdown occur without warning—sometimes while driving 70 mph on cruise control, other times during downshifts or at idle. One owner took the truck to the dealer four times and was headed back a fifth time. Dealers initially couldn't find fault until one captured the failure on a data recorder.
No-start conditions plague multiple owners. The engine cranks normally, fuel pump runs, but ignition won't occur. No check engine light appears. Owners wait 15 to 40 minutes and the truck starts normally. One owner suspected the PASLOCK anti-theft system cutting fuel without reason. Dealers cannot diagnose if the failure doesn't happen at the shop.
Radiator hose chafing caused one truck to overheat and get towed; a second truck in the same fleet showed identical damage before failure. The bottom hose was rubbing the frame rail.

Failure modes owners describe
Valve and valve seat failure
Burnt valves or failed valve seats causing loss of compression in affected cylinders. One owner reported cylinder #4 valve broke in two places with cylinder #2 damaged. Service bulletins existed for 2005-2006 models but not 2007, though dealers acknowledged similar failures occurring in 2007 trucks.
When: 75,000 miles; approximately 107,000 miles
Symptoms owners cite: Engine missing on one cylinder; Check engine light; Reduced power warning; Abnormal idling; Oil leaking; Loss of compression in cylinder
Repairs/costs cited: One owner cited repair cost of approximately $2,800; dealer offered 50% coverage. Another owner's independent mechanic diagnosed four cylinders defective and needing replacement.
Recalls/TSBs owners mention: Service bulletins issued for 2005-2006 Colorados covering repairs up to 100,000 miles at no charge. 2007 models had no bulletin or recall; Chevrolet offered 50% cost-sharing on one case citing it as unusual.
Engine stalling and shutdown during operation
Engine shuts off completely or stalls while driving or idling, sometimes requiring extended wait periods before restart. Multiple owners reported repeated incidents. One owner noted failures occurring with and without cruise control active.
When: 6,796 miles to 12,647 miles; recurring after 10 minutes of driving in one case
Symptoms owners cite: Engine shuts off while driving at highway speed; Engine stalls during idle; Engine stalls when shifting to neutral; Loss of power while cruise control active; Stalling after sitting parked; Multiple stalls requiring several minutes before restart
Repairs/costs cited: Dealers unable to diagnose in early reports; one dealer used recorder to capture fault data snapshots after multiple failures.
No-start condition with intermittent fuel system issues
Vehicle fails to start on numerous occasions, sometimes after sitting idle for hours or days. Fuel pump runs but ignition does not occur. No check engine light or diagnostic codes appear. Owners suspect fuel filter clogging or fuel system blockage. One owner mentioned PASLOCK system (anti-theft fuel cutoff) shutting off fuel supply without apparent reason.
When: 44,000 miles to 100,000 miles; intermittent occurrences
Symptoms owners cite: Fails to start after sitting parked; Cranks normally but won't fire; No check engine light; No diagnostic codes present; Fuel pump running during no-start; Restarts after 15-40 minutes of waiting; Warning light illuminates (unknown type)
Repairs/costs cited: Dealer unable to diagnose because failure did not occur at dealership. Owners replaced battery without resolution.
Bottom radiator hose chafing and puncture
Bottom radiator hose rubs against frame rail, causing hole or damage that leads to coolant loss and overheating. Two vehicles in one fleet both experienced or were at risk of the same failure due to improper hose routing or frame clearance.
When: Fleet vehicles; discovered before catastrophic failure in one case
Symptoms owners cite: Vehicle overheated; Hole in radiator hose; Constant rubbing damage to hose
Repairs/costs cited: Hose replacement required. One vehicle towed due to overheating.

A quarter of owners report trouble before 29,000; a quarter make it past 100,000. Maintenance history matters more than the odometer alone — this is the reported failure window, not a guarantee.

Independent shops typically charge around $3,100 for engine repairs on this vehicle. Dealer pricing tends to run 20-40% higher. The exact figure depends on the specific failure mode, parts availability, and your local labor rates. If you're outside factory warranty, an extended service contract often covers this category.
