Chevrolet Colorado · Pickup
2.5L Ecotec with port and direct injection. The most reliable Colorado powertrain — fewest complaints per unit sold. 200 hp is barely adequate for a truck. Brake vacuum pump is the one known weakness. Paired exclusively with the 6L50 6-speed auto.
2.5 I4 — the invisible Colorado
200 hp base engine: nobody cross-shops this. Slow from a dead stop, adequate at highway speed. No turbo, no diesel emissions, no 8-speed shudder — it runs the 6L50 6-speed. The brake vacuum pump is the main known failure. An honest work truck engine for light duty.
Engine Weaknesses 1
The brake vacuum pump can fail and damage the exhaust camshaft during failure. Affects braking performance. The 2.5L is otherwise very reliable — this is its main known weakness.
Symptoms: Spongy brake pedal, longer braking distances, camshaft noise
Vehicle Weaknesses 7
Corroded connectors in the power steering system cause sudden assist loss. NHTSA recall 16V054 covered 2015 models (60,678 vehicles). 2016-2018 similar, covered by TSB 16-NA-065.
Torque converter clutch material contaminates fluid, causing shudder at light throttle. GM TSB 18-NA-355 calls for fluid flush. Class action filed covering 800k+ units.
Transfer case actuator motor, wiring chafing, or control module prevent 4WD engagement. Service 4WD message common in cold weather. Check actuator wiring at frame crossmember first.
Leaf spring packs develop metal-to-metal contact as dampers wear. GM TSB addresses it with updated damper inserts.
Thin rear frame section allows visible bed movement at highway speed. At max GVWR the frame visibly flexes.
A/C compressor clutch or high-pressure switch fails. BCM temp sensor wiring can prevent compressor engagement.
MyLink system suffers software glitches: black screens, frozen displays, Bluetooth failures. Reset by holding Home + Fast Forward for 10 seconds.
