Chevrolet common problems & weak spots
The most widely documented Chevrolet weak spots in Canada: what breaks, what it costs to fix, and what to inspect before buying used.
Known issues
-
Watch out
2.4L Ecotec oil consumption (Equinox, Terrain 2010\u20132017)
The 2.4 Ecotec drinks oil and can seize if the level drops. Check it every 1,000 km \u2014 the oil light comes on too late.
-
Common
Cruze 1.4T coolant leaks
Water pump, thermostat housing and turbo oil/coolant feed lines leak on the 1.4 turbo. A sweet smell under the hood is the giveaway.
-
Watch out
AFM lifter failure on 5.3L V8 (Silverado, Tahoe)
Active Fuel Management lifters collapse, wiping cam lobes \u2014 a ticking noise on startup is the early warning. Later DFM engines are better but not immune.
-
Common
8-speed transmission shudder (2015\u20132019 trucks)
Torque converter shudder feels like driving over rumble strips. A fluid flush with the updated GM fluid often cures it \u2014 don\u2019t let a shop sell you a rebuild first.
Chevrolet Equinox
-
Watch out
2.4L oil consumption (2010\u20132017)
The second-gen Equinox\u2019s 2.4 is one of GM\u2019s worst oil drinkers. Check oil weekly; many engines died from neglected levels.
Chevrolet Cruze
-
Common
1.4T cooling system leaks
The Cruze\u2019s 1.4 turbo leaks coolant from the water pump, thermostat housing and turbo lines. Budget for cooling work on any used example.
Chevrolet Silverado
-
Watch out
AFM/DFM lifter failures (5.3L)
Cylinder-deactivation lifters fail on 2007\u20132013 trucks and some 2019\u20132021 models. A startup tick means get it diagnosed before the cam is wiped.
