Chevrolet Equinox
2.4-liter Ecotec flex-fuel variant of the LAF. Identical construction, identical problems. Piston rings wear, engine burns oil, timing chain stretches. Only difference from LAF: E85 capable.
The forty-two-million-dollar oil burner
The 2.4L Ecotec is the reason GM paid a $42 million settlement. Cheap low-tension rings, early timing chain stretch, and if you miss an oil check once the engine eats itself. Drives slow, sounds strained, feels like work. A grocery hauler for people who had no other choice.
Vehicle Weaknesses 6
NHTSA investigated 781,000 Equinox/Terrain 2010–2012 for sticking steering. GM replaced steering gear via service bulletin, no formal recall.
The 6T45/6T70 6-speed shows flares on 2-3 and 3-4 shifts caused by AFL accumulator bore wear and debris blocking channel plate passages.
The A/C compressor internally locks up. Engine stalls when A/C is engaged, belt chirps on startup, often preceded by grinding noise.
Faulty wheel speed sensors trigger StabiliTrak/ABS warnings. Especially vulnerable in winter from salt and moisture.
Front wheel hub bearings on the GMT172 wear noticeably early. Hum starts around 80,000 mi, often both sides within months of each other.
Blend door actuators on the second generation fail as early as on Gen 1. Clicking behind the dash, temperature cannot be regulated.
