Reliability report · 2016 Chevrolet Equinox · Updated July 2026

A second-generation 2.4L that quietly drinks oil — buyable only with the timing-chain and oil history in hand.

The 2016 uses GM's 2.4-liter Ecotec four-cylinder (engine code LEA), and its defining problem is excessive oil consumption with no warning light and no visible leak — owners in the federal file describe losing a quart a month and topping off between changes, several of them citing a class action.

The reason it matters: low oil starves the timing chain and cam phasers, which independent mechanics say need replacing around 100,000 miles on these engines anyway. Catch it late and you are into a timing-chain job or a damaged engine. There is no active GM special coverage for oil consumption on a 2016, so a used buyer is on their own — which makes the maintenance records, not the mileage, the thing to inspect.

Canary status

Squawking

What that means: 391 federal complaints, dominated by the 2.4L engine's excessive oil consumption — a slow, no-warning-light drain that starves the timing chain. Only one recall (a label), but the expensive pattern is the engine, and there is no active GM coverage for it on this year.

2.4L excessive oil consumption — the whole story starts here

major
  • 2.4L Ecotec I4

The single loudest pattern in the 2016 complaint file: the 2.4L Ecotec (LEA) burns oil with no leak and no low-oil warning until it is dangerously low. Owners report a quart every 600–1,000 miles. Left unchecked, the chain reaction is real — a clogged PCV (positive crankcase ventilation) system builds crankcase pressure and pushes oil past the rear main seal, and chronic low oil accelerates timing-chain and cam-phaser wear. GM acknowledged 2.4L oil consumption in special coverages on earlier model years, but none of them reach 2016, so the repair is on the owner. Check the dipstick cold, ask how often oil was added between changes, and treat 'it just needs topping off' as the warning it is.

This is a 2.4L Ecotec I4 problem. The 1.5L turbo I4, 2.0L turbo I4, and 1.6L turbodiesel don’t share it.

Timing chain and cam phasers — plan for it around 100kmajor

  • 2.4L Ecotec I4

Independent mechanics who work on these engines are blunt: the 2.4L timing chain, cam phasers, and guides wear out and should be replaced around 100,000 miles — one shop says it does 'probably one every two weeks.' Video of a torn-down 2.4 shows a snapped plastic chain guide that, in the mechanic's words, was 'on the verge of jumping and destroying the motor.' The tell is a rattle from the engine on start-up and timing-related codes (cam/crank correlation). This is the expensive downstream of the oil-consumption problem: keep the oil full and it's routine maintenance; run it low and it becomes an engine. On a high-mileage 2016, a documented chain job is a plus, not a red flag.

Windshield wipers can quit mid-storm — GM Special Coverage 10232660moderate

A cluster of 2016 owners report the front wipers suddenly stopping, stuck mid-sweep, in heavy rain — a genuine visibility hazard. GM issued a Special Coverage (a defect-specific extended-warranty program) — internal number 10232660 — for 2016–2017 Equinox and GMC Terrain covering front wiper-module ball joints that corrode and separate from their sockets, which kills the wipers. Dealers replace the front wiper transmission. If the wipers ever hesitated, ask whether this coverage was used; verify the exact mileage and time limits in the bulletin.

Stalling and loss of powermoderate

  • 2.4L Ecotec I4

Beyond oil, the 2016 file carries scattered reports of the engine stalling or losing power while driving, sometimes with a fuel odor. Several trace back to the same neglected-oil chain of events; others are fuel-delivery related. None is a recall on this year, so any drivability complaint on a test drive is worth a pre-purchase diagnostic scan rather than a shrug.

The oil seems to disappear faster than the sensor can tell me — no leak, no warning light.
