Known problems
- Worth watching
Automatic transmission shift irregularities (early reports)
Symptoms: self-shifting into Neutral while driving, hesitation or a harsh downshift, or difficulty selecting a gear; a few reports describe an outright transmission failure with a fluid leak at low mileage
What to do: If you notice any of these symptoms, get the transmission diagnosed promptly and keep the service record — this is an early, unconfirmed pattern in a brand-new generation, not yet a recall or TSB.
- Worth watching
Dashboard reflections obscuring the windshield
Symptoms: the dashboard or interior trim reflects onto the windshield in sun or oncoming headlights, obscuring the road, especially pedestrians
What to do: If dash glare is bothering you, ask about a dash-mat accommodation — as of this writing there's no recall or redesign, just an informal fix offered by some dealers.
- Worth watching
OnStar/telematics module failure, sometimes with display blackout
Symptoms: the OnStar/telematics control module fails, causing parasitic battery drain and loss of connectivity; a subset of reports describe the instrument cluster and infotainment screens going blank while driving
What to do: If OnStar stops responding or the battery drains overnight, have the telematics module checked; if any display blanks out while driving, treat it as a priority repair even though it isn't yet the subject of a recall.
Service schedule
| Item | Interval | Notes |
|---|---|---|

Known problems
- Critical
Front passenger airbag occupant-classification sensor fault (2023 only)
Symptoms: the front-passenger seat's occupant-classification sensor, used with ventilated seats, can malfunction
What to do: Confirm this recall was completed on any 2023 Equinox with ventilated front seats — a faulty sensor can prevent the airbag from responding correctly to who's in the seat.
- Critical
Fuel pump control module fault (2021-2022)
Symptoms: the low-pressure fuel pump's control module can fail to consistently deliver fuel, causing the engine to stall while driving
What to do: Confirm this recall was completed on any 2021-2022 Equinox — this is a different component from ordinary fuel-pump wear complaints, addressed by a dealer software/module fix.
- Critical
Fuel tank seam leak (AWD, 2019-2020)
Symptoms: a poorly sealed seam near the fuel tank inlet can leak fuel
What to do: Confirm this recall was completed on any AWD 2019-2020 Equinox — a fuel leak near an ignition source is a fire risk.
- Critical
Right-front intermediate driveshaft fracture (2018 only)
Symptoms: the right-front intermediate driveshaft can fracture or separate while driving, causing a sudden loss of propulsion; if parked on a grade without the parking brake applied, the vehicle can roll away
What to do: Confirm this recall was completed on any 2018 Equinox — always set the parking brake on a grade regardless, but especially on an unrepaired vehicle.
- Critical
Seat belt fastening bolt defect (2021 only)
Symptoms: a seat belt may be secured with an incorrect fastening bolt
What to do: Confirm this recall was completed on any 2021 Equinox — an incorrectly fastened seat belt may not restrain properly in a crash.
- Worth watching
Brake vacuum pump wear
Symptoms: a harder brake pedal and reduced power-assist, sometimes with a brake warning
What to do: The turbo engines rely on a camshaft-driven vacuum pump for brake assist; if the pedal firms up, have the pump checked, since worn units are a known wear item on these engines.
- Worth watching
Cold-weather turbo/intercooler icing (reduced power)
Symptoms: sudden loss of power or a reduced-power/limp mode with codes such as P0299, plus misfires, when driving in freezing temperatures
What to do: This is condensation freezing in the charge-air system in hard frost; have the current wastegate-solenoid and intercooler service updates applied and let the engine warm before heavy load in extreme cold.
- Worth watching usually from 25,000 mi (40,000 km)
High-pressure fuel pump / fuel-delivery faults
Symptoms: hesitation, sputtering, sudden power reduction or stalling while driving
What to do: If the engine hesitates or drops into reduced power, have the high-pressure fuel pump and fuel system diagnosed rather than ignoring it, as it can leave you stranded.
- Good to know
Start/stop (auto-stop) faults
Symptoms: the auto stop/start not working or throwing a message; some cars needed battery or accumulator attention
What to do: Have the 12V battery and start/stop system tested before assuming a fault; check whether your VIN falls under the start/stop accumulator recall on early cars.
Service schedule
| Item | Interval | Notes |
|---|---|---|
| Engine oil & filter change | every 7,000 mi (12,000 km) or 12 months | follow the Oil Life monitor; halve for short-trip or cold-climate use |
| Cabin air filter | every 22,000 mi (35,000 km) | — |
| Engine air filter | every 37,000 mi (60,000 km) | — |
| Spark plugs | every 60,000 mi (97,000 km) | petrol only; the turbo engines can benefit from an earlier check |
| Brake fluid Important | every 36 months | — |
| Timing chain (no scheduled replacement) | — | the 1.5 and 2.0 turbos are chain-driven; inspect only if a cold-start rattle appears |

Known problems
- Critical
2.4 Ecotec balance-shaft/timing-chain wear
Symptoms: a cold-start rattle that can progress to chain stretch and brittle timing-chain guides breaking, since low oil (from the oil-consumption defect) drops hydraulic tensioner pressure
What to do: Don't dismiss a cold-start rattle on the 2.4 Ecotec — it's frequently tied to the same oil-consumption defect above, and worst-case chain/guide debris causes catastrophic engine damage. Have oil level and the chain checked together.
- Critical
Electronic park-lock rollaway risk
Symptoms: the ignition key can be removed without the transmission actually being in Park
What to do: Confirm this recall was completed on your VIN — always double-check the shifter is fully in Park before exiting, especially on an unrepaired vehicle.
- Critical
Windshield wiper module ball-joint corrosion
Symptoms: one or both windshield wipers can become inoperative as the wiper-module ball joints corrode and wear over time
What to do: Confirm this recall was completed on your VIN — inoperative wipers in rain or snow are a real visibility hazard.
- Critical usually 30,000–70,000 mi (48,000–113,000 km)
2.4 Ecotec (LAF/LEA) excessive oil consumption
Symptoms: oil consumption as severe as 1 quart per 1,000-2,000 miles with no visible leak, from worn or broken piston rings
What to do: Check the oil level regularly between changes. GM's special coverage and a 2019 class-action settlement both cover free piston-ring replacement for 2010-2013 models within their mileage/age windows — check whether your VIN still qualifies before paying out of pocket. Left unaddressed, this can progress to full engine failure.
- Worth watching
Momentary increase in steering effort
Symptoms: after sustained straight-line highway driving (30+ minutes) without turning the wheel, steering can momentarily feel heavier
What to do: This was investigated by NHTSA and closed without a recall — GM's redesigned steering gear (available via a 2014 service bulletin) was found an adequate remedy. If you notice this, have the steering gear checked/updated rather than assuming nothing can be done.
Service schedule
| Item | Interval | Notes |
|---|---|---|
| Engine oil & filter change | every 7,000 mi (12,000 km) or 12 months | follow the Oil Life Monitor — treat this as a cap, not a fixed interval; it fires sooner under short-trip or cold-climate use |
| Cabin air filter | every 22,000 mi (36,000 km) | — |
| Engine air filter | every 45,000 mi (72,000 km) | — |
| Transmission fluid Important | every 45,000 mi (72,000 km) | 6-speed automatic (6T70/6T75 family) |
| Spark plugs | every 97,000 mi (156,000 km) | petrol engines only |

| Brake fluid Important | every 36 months | — |
| Timing chain inspection | — | chain-driven, no scheduled replacement — but the 2.4 Ecotec's balance-shaft chain is a known wear point tied to oil consumption; investigate any cold-start rattle promptly (see known issues) |

Lab-cycle figures, each shown with the cycle it was measured under — the same car under EPA, WLTP, NEDC or JC08 can differ by up to 20%. Real driving always falls short of the declared figure: roughly 10–20% on an EPA rating, 15–30% on a WLTP or NEDC one. That gap is normal, not a fault.
