The 2023 Equinox is too new for widespread pattern failures, but its 1.5L turbo engine carries forward catastrophic oiling issues from the 2018-2022 generation that destroy internals prematurely. Early reports suggest GM hasn't fully resolved the piston ring carbon buildup and oil consumption problems.
1.5L Turbo Catastrophic Oil Consumption / Engine Failure
Common · high severityTypical onset: 30,000-70,000 mi
Symptoms: Excessive oil consumption (1+ qt per 1,000 mi), Blue smoke on startup or acceleration, Check engine light for misfires (P0300 series), Knocking/ticking from engine, Complete engine seizure in severe cases
Fix: Carbon buildup on piston rings causes oil burning, eventually scoring cylinders. Requires complete engine rebuild or short block replacement. 18-24 labor hours for full teardown, bore inspection, piston/ring replacement, and reassembly. Many shops opt for reman short block swap to avoid liability.
Estimated cost: $6,500-9,500
Transmission Oil Cooler Line Leaks
Occasional · medium severityTypical onset: 40,000-80,000 mi
Symptoms: Transmission fluid puddles under vehicle (front-center), Low transmission fluid warning, Harsh or delayed shifts, Overheating transmission on highway drives
Fix: Quick-connect fittings on cooler lines crack or O-rings fail where they mate to radiator. Requires replacement of affected line(s) and possibly radiator-side fittings. 2-3 hours labor if no radiator removal needed, 4-5 if radiator must come out for access.
Estimated cost: $450-850
Transmission Mount Failure
Occasional · low severityTypical onset: 50,000-90,000 mi
Symptoms: Clunking when shifting from Park to Drive/Reverse, Excessive vibration at idle, Drivetrain shudder on acceleration, Visible sagging or torn rubber on mount
Fix: Hydraulic transmission mount on driver side deteriorates from heat and stress. Replacement requires supporting transmission, removing 3-4 bolts. Straightforward 1.5-2 hour job.
Estimated cost: $250-450
Fuel System Low Pressure Issues
Occasional · medium severityTypical onset: 60,000-100,000 mi
Symptoms: Hard starting after sitting, Engine stumbles or hesitates under load, P0087 or P0089 fuel pressure codes, Intermittent stalling
Fix: Fuel filter integrated into pump module can clog prematurely, or high-pressure pump on engine develops internal wear. Filter requires tank drop (3-4 hours); high-pressure pump replacement adds 5-6 hours due to intake manifold removal. Diagnostics critical to avoid replacing wrong component.
Estimated cost: $800-1,800
Turbocharger Wastegate Rattle/Failure
Occasional · medium severityTypical onset: 70,000-110,000 mi
Symptoms: Rattling noise from engine bay (sounds like marbles), Loss of power under acceleration, P0299 underboost code, Excessive black smoke under load
Fix: Wastegate actuator arm or flapper valve wears, causing rattle and eventual boost control loss. Turbo replacement required as wastegate isn't serviceable separately. 6-8 hours labor for removal, new turbo install, and oil feed/return line replacement.
Estimated cost: $2,200-3,500
Hard pass until 2025+ model years prove the 1.5T oil consumption issue is truly fixed — too many $8K engine rebuilds on barely-driven examples from prior years.
