2023 Chevrolet Colorado Reliability Report

After a right turn, the turn signal flips to the left side on its own. The stalk can also stick so the opposite signal will not engage. Upper radiator hoses leak coolant, which raises the risk of overheating, and replacement parts can be on backorder. The roof can dent at a car wash. A GM service bulletin calls for roof reinforcement on trucks built before February 3, 2025, but some owners are refused the repair. Other reports cite phone connection drops, batteries that keep dying, and lane keep assist shutting off without warning.

Upper radiator hoses leak where they connect to the radiator, and owners describe it as a widespread failure on these trucks. Coolant can spray onto a hot engine, and owners worry about fire or overheating. Other reports describe sudden power loss at highway speed. In one, the engine downshifted and shut off at 75 mph and needed a new fuel pump power control module. In another, the truck slowed from 70 to 30 mph with a misfire at 3,000 miles, and repeated dealer visits did not fix it. One oil leak after a recall repair left the dipstick dry.

Reports here cover the cooling system, the electronics, and the transmission. Low coolant flow codes come back even after a warranty coolant pump replacement, and the upper radiator hose leaks where it meets the radiator. Body control module faults knock out the locks, the windows, and the 4WD display, and dealers repeatedly find no fault. The transmission shifts hard between first and second on the first drive of the day, which dealers call normal. One transmission failed on the freeway. A crankshaft seal failed at 69,000 miles and drained the oil without turning on any warning light.

The same right-to-left turn signal fault shows up most often here. One dealer tried 3 times to fix it without success, and drivers report near collisions when others misread the signal. More serious reports pair heavy steering with weak brakes, along with "Service Power Steering" and "No Assist Soon" warnings. In one truck this happened twice, the second time at about 24,000 miles, and another owner linked it to an aging battery. A front suspension squeak at low speed continues even after the bushings were replaced.

After a right turn, the left turn signal flashes on its own for a few seconds. This is the most common complaint in this category. It happens at any speed, and owners whose dealers replaced the turn signal switch say the problem remains. Other drivers can misread the false signal. With a trailer connected, the left signal may flash rapidly and fail the onboard trailer light test. Single reports describe an instrument panel that stays blank at startup and false braking under adaptive cruise control.

The blind spot warning lights up with no vehicle nearby, often at night, and sometimes misses real cars. With lane assist on, a false alert can steer the truck back as the driver changes lanes. Some reports say both mirror lights stay on and the windows stop working. Dealers often cannot reproduce the fault, and in one case a door sensor replacement did not help. Problems start early, within days of purchase or near 3,000 miles. Several owners also report sudden automatic braking to a full stop, including once at 75 mph.

The roof panel caves in under car wash blowers and then pops back out with a loud bang. One report says it also pops at highway speeds. One truck had the problem at just 10 miles. A dealer diagnosed a structural roof failure but did not repair it. Neither report mentions injury or loss of control, but the problem can appear on a brand-new truck.
