The 2024 Equinox EV is brand-new to market on GM's Ultium platform, so long-term failure data is minimal. Early warranty claims show drive unit concerns, cooling system issues, and typical first-year EV teething problems—but it's too soon to establish clear patterns.
Drive Unit / Electric Motor Noise and Seal Leaks
Occasional · medium severity
Typical onset: under 20,000 mi
Symptoms: Whining or humming from front or rear drive unit that changes with speed, Fluid seepage around drive unit housing seams, Reduced power or regen braking inconsistency, Service messages for drivetrain system faults
Fix: Early production units showing seal leaks and bearing noise—some requiring complete drive unit replacement under warranty. Out-of-warranty involves R&R of drive unit (4-6 hours labor), fluid refill, and potential relearn procedures. GM has issued TSBs for some VINs requiring software calibration updates first.
Estimated cost: $3,500-6,500
Inverter Cooling System Failures
Occasional · high severity
Typical onset: 10,000-30,000 mi
Symptoms: Reduced propulsion power warning on dash, Vehicle enters limp mode or refuses to charge, Coolant leaks near inverter housing or undercarriage, Check engine light with codes for inverter overtemp
Fix: Ultium inverters use dedicated coolant loop—failures traced to faulty coolant pumps, clogged heat exchangers, or leaking hose connections. Inverter R&R is 6-8 hours, requires high-voltage lockout procedures and specialized scan tools. Some cases need inverter replacement ($4k part alone), others just pump/hose service (2-3 hours).
Estimated cost: $1,200-7,000
12V Battery Drain / Accessory System Faults
Common · medium severity
Symptoms: Vehicle won't wake from sleep mode, dead 12V battery, Infotainment system randomly reboots or freezes, Climate control stops responding, Door locks cycling on their own or failing to lock
Fix: GM's new electrical architecture has software bugs causing parasitic draw—multiple OTA updates issued. Some vehicles need 12V battery replacement (AGM, $250-350 part) plus module reprogramming (1.5-2 hours). Occasionally requires body control module reflash or replacement if corrupted.
Estimated cost: $400-1,200
AC Evaporator Clogging / Refrigerant Leaks
Occasional · low severity
Typical onset: 15,000-40,000 mi
Symptoms: Weak or no cold air from vents, Musty odor from HVAC system, AC compressor cycling excessively or not at all, Low refrigerant warnings on service scanner
Fix: Heat pump systems in EVs run year-round for cabin heating/cooling—accelerates evaporator debris buildup and corrosion. Evaporator R&R requires full dash removal (8-10 hours labor), system evacuation/recharge. Some cases just need expansion valve or drier replacement (3-4 hours).
Estimated cost: $1,800-3,200
Transmission Mount and Subframe Bushing Failures
Occasional · low severity
Typical onset: 25,000-50,000 mi
Symptoms: Clunking or thudding over bumps from front end, Vibration during acceleration or regen braking, Steering wheel shudder at low speeds, Visible tearing or separation of rubber mount material
Fix: Single-speed transmission and heavy battery pack stress front subframe mounts—early wear on some builds. Front drive unit mount replacement is 2-3 hours, rear subframe bushings add another 2 hours if also torn. Alignment recommended after subframe work.
Estimated cost: $600-1,400
High-Voltage Battery Management System Glitches
Rare · high severity
Symptoms: Sudden loss of all propulsion power while driving, Charging stops prematurely or won't initiate, Battery range indicator jumping erratically, Fault codes for battery isolation fault or cell imbalance
Fix: A few isolated cases of BMS module faults or cell sensor failures requiring battery pack access. Diagnosis requires DC isolation testing and cell voltage mapping (3-4 hours). Module replacement involves partial pack disassembly (6-10 hours). Full pack replacement reserved for catastrophic failures—$15k-20k part cost, 12-16 hours labor.
Estimated cost: $2,000-25,000
Owner tips
Perform inverter coolant flush every 100k miles or 5 years—contamination kills pumps and clogs heat exchangers early
Keep 12V battery on trickle charger if vehicle sits unused more than 2 weeks—prevents module corruption
Document all software update history—many drivetrain faults are TSB-covered and need specific calibration sequences
Check drive unit fluid level at 30k and 60k miles—factory fills sometimes low, and seal weeps can drain unnoticed
Too new to recommend used—most units still under warranty with unproven long-term durability; wait 3-5 years for real-world failure data to emerge.

Fitment notes: 12V auxiliary battery for vehicle systems; main propulsion is electric drivetrain with high-voltage battery pack
