Why it cuts both ways
The 2015 Equinox is part of the second generation (2010–2017). It came with two very different engines: the 2.4-liter Ecotec four-cylinder (by far the most common) and an optional 3.6-liter V6. It's comfortable, roomy, and inexpensive to buy — but the engine under the hood changes the entire ownership story.
The 2.4-liter oil-consumption problem
This is the one that matters. The 2.4-liter Ecotec in these years has a documented tendency to burn oil — worn piston rings letting the engine consume oil well beyond normal, in bad cases needing a top-up every few hundred miles. Left unwatched, low oil can starve and damage the engine. General Motors acknowledged it in service bulletins and it drew class-action attention, but there was no full recall, so a buyer today carries the risk. Some cars also show timing-chain wear. If you're looking at a 2.4-liter, an oil-consumption check and a paper trail of oil changes are everything.
The V6 is the safer pick
The 3.6-liter V6 avoids the oil-consumption issue. It had its own timing-chain history in earlier years that was largely improved by this point, and it's the engine to prefer if the price and condition are right. Confirming which engine a given Equinox has is the first question, not the last.
Open recalls — check the VIN
Recall status is VIN-specific and cannot be assumed from the model year. Look up any 2015 Equinox's open recalls free by VIN at NHTSA; a Chevrolet dealer completes any open recall at no charge. Note that the oil-consumption issue itself was handled through service bulletins, not a recall — so it will not necessarily show up in a recall search.
What a history report tells you — and what it doesn't
On a car like this, the individual car's history is most of the decision. A history report is a record of what got reported — title brands, reported accidents and damage, odometer readings over time, and service records where they exist. That is what separates a clean, maintained example from a salvage-title or flood car wearing the same badge.
What a history report is not is a forecast, and an absence of records is not proof of a clean past — plenty happens to a car that never gets reported. That is why the honest answer is always the pair: the documented history and an in-person inspection by a mechanic you trust, on the specific car.
On this car especially, service records are the whole game: a documented history of on-time oil changes on a 2.4-liter is worth far more than the same mileage with no paper trail.
The things to check before you buy
- Which engine Confirm 2.4-liter four or 3.6-liter V6 first — it changes everything.
- Oil level and consumption On a 2.4-liter, check the oil on the dipstick, look for blue smoke or misfires, and ask how often it needs topping up.
- Service records A paper trail of consistent oil changes is essential on the four-cylinder.
- Recall status Confirm any open recalls are completed on this VIN.
- Accident and rust The usual panel and underbody checks.
What would make you walk
- A 2.4-liter actively burning oil Needing frequent top-ups, blue smoke, or misfires — with no maintenance history.
- No service records on a four-cylinder On this engine, that's a gamble, not a bargain.
- Engine knock or warning lights Do not assume these are minor on this powertrain.
- Structural damage or rust The usual deal-breakers.
