Used Chevrolet Equinox 3rd Gen (2018-2024): Buyer's Guide

The 2018 Chevrolet Equinox logged 362 NHTSA complaints in its first model year. The 2023 logged 72. Same platform. Same basic dimensions. Completely different ownership experience. The gap isn't random. It maps exactly to when GM dropped two problematic powertrain options and let the 1.5-liter turbo stand on its own. If you know which years to skip and which inspection items to run, the 3rd gen Equinox is a solid compact SUV in the $15,000-$28,000 range. If you don't, you might end up with a shuddering 9-speed or an engine that needs a quart of oil every 2,000 miles.

This is the guide for the night before you go look at one.

This Generation at a Glance

The 3rd gen Equinox launched for 2018 on GM's D2 platform. It replaced the 2010-2017 2nd gen, which had its own notorious oil consumption saga tied to the 2.4L EcoTec engine. The new generation brought a lighter, smaller body with better fuel economy and three powertrain choices at launch.

The story within this generation breaks cleanly into two phases:

Phase 1 (2018-2020): Three powertrain options, two of which became liabilities. This is the complexity era.

Phase 2 (2021-2024): One powertrain, a mid-cycle refresh in 2022, and dramatically lower complaint counts. This is the buy-with-confidence era.

The 2022 refresh brought revised front and rear styling, a new RS sport trim, wireless Apple CarPlay and Android Auto, and available front and rear park assist. Prices actually dropped slightly across the board for 2022.

The diesel was dropped after 2019 due to slow sales, not reliability. The 2.0T was dropped after 2020 because it accounted for roughly 7 percent of Equinox sales. Both of those decisions, made for business reasons, made the Equinox a much more predictable used car to buy.

Powertrain and Trim Breakdown

1.5L Turbo (LYX) — The Mainstay

The 1.5T is in every 3rd gen Equinox ever built. It pairs with a 6-speed automatic in FWD or AWD configuration. It is not a performance engine. At 170 horsepower it moves the Equinox adequately but without urgency. Owners consistently describe the power delivery as sufficient but unexciting.

What owners like: The 1.5T is genuinely efficient. FWD models return 28 combined MPG, which is competitive for a compact SUV. Running costs are low. The 6-speed automatic, while not the most sophisticated transmission on the market, is predictable and has no known catastrophic failure patterns. Consumer Reports ranked the 3rd gen Equinox as the second most reliable compact SUV in its class behind the Toyota RAV4, ahead of the Honda CR-V, Mazda CX-5, and Nissan Rogue. Long-term forum data backs this up: documented examples at 150,000-200,000+ miles with no major repairs.

The charge air cooler recall. This is the most important 1.5T item to verify on any used Equinox. Under turbo boost, the charge air cooler outlet duct can disconnect from the throttle body. When it does, the engine throws P0299 (underboost) and P1101 (intake air flow performance) codes, triggers a reduced engine power message, runs rough, and can stall at idle. GM issued Emission Recall N192271200 to fix it with an improved retainer. Before you buy any 2018-2019 Equinox with the 1.5T, confirm this recall is complete via VIN check.

Oil consumption. First, a clarification: the $42-45 million GM class action and the earlier NHTSA special coverage adjustments for oil consumption all targeted the 2.4L EcoTec in 2010-2017 models. The 3rd gen uses a different engine. However, a newer class action was filed alleging the 2018+ 1.5T has the same low-tension piston ring defect — carbon deposits cause rings to stick in their lands, allowing oil into the combustion chamber. GM issued Special Coverage Adjustment N192291100 paying for piston/ring replacement past the original warranty, even on 1.5T models. Owner forums document some engines consuming 1.5 quarts per 3,000 miles on 0W-20, dropping significantly when switched to 5W-30 — oil viscosity selection appears to matter on this engine. GM's own "acceptable" threshold is one quart per 2,000 miles. If a car has clean service records and no top-off notes, consumption is likely not a problem. If records show repeated quarts added between changes, that's your red flag. Also note: the piston/ring replacement fix sometimes fails within 20,000-30,000 miles, per owner reports. A clean service history with no consumption notes is more reassuring than a recent repair for oil consumption.

P1101 and the PCV system. P1101 (intake air flow system performance) is one of the most common fault codes on the 3rd-gen 1.5T. The immediate assumption is a failed MAF sensor, but GM TSB PIP54173 tells dealers to check crankcase pressure first. The real culprit is usually a torn PCV diaphragm inside the valve cover or carbon buildup on the throttle body from PCV blowby. Symptoms: rough idle, hesitation under acceleration, cruise control failure. The fix is a PCV valve/diaphragm replacement ($50-$150 DIY) or throttle body cleaning, not a $400 MAF sensor. If a seller says the check engine light was "just a sensor," get the code number.

Intercooler icing in cold weather. In temperatures below 0°F (-18°C), moisture and PCV oil vapor condense inside the intercooler core and freeze, restricting airflow. The result is sudden, severe power loss at highway speed, sometimes with no warning codes. This is not mileage-dependent — it can happen in the first 10 minutes of cold-weather driving. GM issued TSB 18-NA-020 covering 2018-2023 Equinox and Terrain, with a thermostatically-controlled lower grille shutter as the fix. Forum threads describe it as the car "being useless in winter." If you are buying in a cold-climate state, check whether this TSB has been applied and whether the lower grille shutter hardware is installed.

Vacuum pump failure — the most serious 1.5T risk on 2018-2022. The engine-mounted mechanical vacuum pump (which also provides brake booster vacuum) is a documented failure point across 2018-2022 Equinox. When the pump's internal gear shatters, it sends metal debris into the camshaft and timing chain. There is no shear pin to protect the drivetrain. Outcomes range from a "service brake assist" warning to complete engine failure. GM issued Special Coverage N182202780, extending the repair warranty to 10 years or 150,000 miles for this specific failure. The 2023 Equinox switched to an electric power-assisted braking system, eliminating this failure mode entirely. For any 2018-2022 Equinox, confirm via VIN whether this special coverage repair has been performed. If not, budget for it as a future item or negotiate accordingly.

Low-speed jerk. Separate from the 2.0T transmission issue, the 1.5T has documented low-speed jerking at 20-35 MPH, particularly noticeable when lifting off the throttle. Forum threads on terrainforum.net going back to 2019 document this consistently. A transmission fluid change often helps. Not a fatal flaw, but check for it during the test drive.

2018-2019 1.5T verdict: Viable, but verify the charge air cooler recall is complete. Check the oil level carefully. Avoid if service records show multiple quarts added between changes.

2021-2024 1.5T verdict: The sweet spot. Complaint counts dropped dramatically. No known new failure patterns emerged. The 1.5T by this point had TSBs addressing its known issues, and GM's assembly quality on this engine improved year over year.

2.0L Turbo (LTG) — Approach with Caution

The 2.0T was available from 2018 through 2020 only. It makes 252 horsepower, pairs exclusively with a 9-speed automatic (9T65), and requires AWD. It was positioned as the performance option for the Equinox, and on paper, the power jump over the 1.5T is real.

In practice, the 9T65 9-speed transmission has a well-documented shudder problem.

The 9T65 shudder. Owners report a vibration or judder between 20 and 35 MPH, typically at 1,400-1,700 RPM. Most noticeable in stop-and-go traffic and when easing off the throttle. Dealers frequently told owners this was "working as designed." Forum threads on terrainforum.net have pages of documentation going back to 2018. GM identified the root cause as the factory Dexron VI transmission fluid, which is hygroscopic (absorbs moisture) and degrades the torque converter clutch friction coefficient over time. GM issued a TSB to replace the factory fluid with an updated formulation. For severe cases that didn't respond to a fluid change, GM launched a pilot transmission replacement program in December 2020. That program expired December 1, 2021, and only covered vehicles under 18 months from delivery with under 18,000 miles. Any 2.0T you buy today is outside that program.

A fluid change with the updated formulation resolves the shudder in some cases. In others, the judder returns. If buying a used 2.0T post-warranty, factor in the possibility of a full transmission replacement. Repairs run $2,500-$4,500 depending on whether a rebuild or replacement unit is needed.

Higher operating costs. The 2.0T recommends premium fuel, adds cost per tank, and returns 25 combined MPG versus 28 for the 1.5T. Given that the power advantage is rarely usable in a compact SUV, the 2.0T asks you to pay more in every direction.

When the 2.0T makes sense. If you need maximum towing capacity, the 2.0T is rated at 3,500 lbs versus 1,500 lbs for the 1.5T. If you tow regularly, the extra capability matters. Otherwise, the 1.5T is the better used buy.

2.0T inspection protocol. Test drive at 20-35 MPH specifically. Find a spot where you can hold a steady 30 MPH at light throttle. Any vibration, shudder, or judder is the 9T65 telling you what you're dealing with. Walk away unless the price accounts for transmission risk.

1.6L Turbo Diesel (LH7) — The Rare One

The diesel Equinox existed for exactly two model years: 2018 and 2019. GM dropped it for 2020 not because it broke, but because it barely sold. Buyers chose the 1.5T gas engine over the diesel at a rate that made the diesel commercially nonviable. The diesel's 32 combined MPG sounds compelling until you realize diesel fuel cost more than regular unleaded and the fuel economy advantage over the 1.5T was modest.

In the used market, the diesel is genuinely rare. If you find one, be aware of one diesel-specific trap: diesel particulate filter (DPF) regeneration requires sustained highway driving above 35 MPH. If the vehicle is used primarily for short city trips, the DPF cannot complete passive regeneration, eventually triggering "engine power reduced" mode that limits speed to 15-20 MPH. Consumer Reports reviewed the diesel and concluded the fuel savings do not recoup the price premium over the 1.5T. Documented diesel issues also include water contamination in the fuel filter and charge pipe leaks at the turbo-to-intercooler connection.

The bigger practical concern with a used Equinox diesel is finding a mechanic willing to work on it and sourcing parts. Diesel-specific components are low-volume, and some independent shops will refer you elsewhere. Stick to the 1.5T unless you have a specific reason to pursue the diesel.

Trim-Specific Notes

The 3rd gen Equinox runs four trim levels post-refresh (2022+): LS, LT, RS, and Premier.

LS is the base. It gets 17-inch alloy wheels, push-button start, a 7-inch touchscreen, wireless Apple CarPlay and Android Auto, and Chevy Safety Assist (automatic emergency braking, lane keep assist, pedestrian detection, automatic high beams). The LS is a more complete package than its position in the lineup suggests, particularly post-2022 when wireless CarPlay became standard.

LT adds a power liftgate, a sunroof, and a 360-degree camera. The sunroof is worth having. The 360-degree camera is genuinely useful. This is where most buyers should land in the used market.

RS brings the RS sport appearance package: black exterior trim, 19-inch dark wheels, perforated leather seats, red interior stitching. It is a styling choice, not a performance choice. The RS and LT share identical powertrains and mechanical specs. If you prefer the aggressive look and find a well-priced RS, it is mechanically the same as the LT.

Premier is the top trim. It adds the 8-inch Infotainment 3 Plus touchscreen with built-in navigation, adaptive cruise control, front and rear park assist, and automatic parking assist. The tech package is the reason to pay up for a Premier. Adaptive cruise control in this price range is genuinely useful. The Premier also gets dual-zone automatic climate control.

One caution on 2018-2019 pre-refresh trims. The 2018 Premier came standard with the 2.0T, which bundled the 9-speed shudder risk with the top-trim price point. Many 2018 Premier listings you'll find used are 2.0T equipped. Check the spec sheet before you assume.

Which Model Years to Target Within This Gen

2018 is the year to skip. Every problem this generation has shows up in 2018 data. The 2018 had five NHTSA recalls, including two serious safety items: a driveshaft fracture recall (17V516000) where the right front intermediate driveshaft could separate while driving, and a high-pressure fuel pump weld failure recall (18V358000) where an improperly welded pump joint could cause fuel leakage and fire risk. These recalls should be closed on any surviving 2018 by now, but verify via VIN before you buy. First-year refinement issues throughout the 1.5T. The 2.0T with its 9-speed was brand new to the platform. The complaint count reflects all of it.

2019-2020 are the caution years. If you find a 1.5T-only 2019 or 2020 at the right price, it can work. Verify it is not the 2.0T. Check the charge air cooler recall completion. The 2019 was also the last year of the diesel, which is mostly a curiosity but worth knowing for parts availability reasons.

2021 is the first genuinely clean year. The complaint count dropped from 259 to 76, a 71 percent reduction. That maps to the 2.0T leaving the lineup. The 2021 has pre-refresh styling and the 7-inch infotainment, but mechanically it's the best year before the 2022 refresh. If you find a well-priced 2021, it is a smart buy.

2022 gets the new styling and the RS trim, but Consumer Reports scored it 1.0 out of 5.0 for reliability — the worst year in this generation. Problems concentrated in infotainment, a fuel pump recall (N222372310 for some units), and rear brake rubbing. CR pulled its "recommended" designation for the Equinox specifically because of 2022 data. The 2022 also still has the vacuum pump failure risk. If you want the refreshed look, skip 2022 and spend slightly more for a 2023.

2023 is the sweet spot. Two things changed: the 2023 switched to electric power-assisted braking, permanently eliminating the vacuum pump failure chain that threatens 2018-2022 engines. And GM bumped output to 175 hp. Consumer Reports returned to above-average reliability for 2023. The 2023 recorded only 72 NHTSA complaints for the full year — low for a compact SUV with 3,000+ listings on the used market. Inventory is deep. This is the buy.

Pre-Purchase Inspection Checklist

For Every 3rd Gen Equinox

• Run the VIN through a recall check before you drive anywhere. Use CarScout's recall lookup. On 2018 models, confirm these are closed: N192271200 (charge air cooler duct), 17V516000 (driveshaft fracture), 18V358000 (fuel pump weld, fire risk), and 18V279000 (HVAC airflow calibration). On 2018-2019, also verify 20V668000 (start/stop accumulator missing bolts, transmission oil leak and fire risk). On 2019-2020 AWD, verify 19V667000 (fuel tank seam, fire risk).
• Check the oil level cold. Pull the dipstick before the engine starts. Note the level. If the owner doesn't know when the last oil change was, that's a red flag. If oil is visibly low, walk away.
• Look at the oil on the dipstick. Dark brown is normal. Black and gritty or milky and foamy means combustion gases or coolant contamination. Neither is acceptable.
• Start the engine cold. Listen for a tick that follows RPM. Some valvetrain noise on startup is normal and fades. A persistent tick that stays at operating temperature is a sign of oil starvation or lifter wear.
• If buying in a salt-belt state, inspect the rocker panel crimps and pinch welds behind the plastic cladding. These are hidden rust points on 3rd-gen Equinox in northern/high-salt climates. Also check door hem seams and subframe mounts. GM's warranty covers rust-through (perforation) only, not surface rust.
• For 2018-2022: check Special Coverage N182202780 status. The mechanical vacuum pump can shatter and send debris into the engine. Ask the seller or a dealer to pull the VIN service history and confirm this special coverage repair has been performed. If not, the 10-year/150,000-mile coverage window may still be open. Note: 2023+ eliminates this failure mode with electric power braking.
• Ask for service records. Any record of oil top-offs between changes documents consumption. Multiple quarts added between services is a hard stop.

For 2018-2020 2.0T Models (9-Speed Test)

• Drive at exactly 25-30 MPH at light throttle. Hold it steady for 30 seconds. Any vibration, shudder, or judder from the drivetrain is the 9T65 showing you its issue. This test is binary. Either you feel it or you don't.
• Merge onto a highway or accelerate from 20 to 50 MPH. The 9-speed upshifts through multiple gears in this range. Listen for clunks, hesitation, or a surge. These are transmission calibration issues.
• Ask the seller directly if they've experienced transmission shudder. If they say it was "fixed under warranty," ask for the dealer invoice. A transmission fluid exchange is a soft fix. A torque converter replacement or transmission replacement is the real fix.

For 1.5T Models (All Years)

• Test low-speed throttle lift-off. In a parking lot, accelerate to 25 MPH and lift off the throttle completely. Any jerk, clunk, or vibration from the drivetrain can indicate transmission fluid condition. A fluid change often resolves this if caught early.
• Check for check engine codes via OBD-II. P0299 (underboost) or P1101 (intake air flow performance) indicate the charge air cooler recall issue may not be resolved, or that the fix has failed.

Running Costs

Timing chain inspection at 100,000 miles is a commonly cited maintenance item for the 1.5T. Replacement if needed runs $800-$1,500 at an independent shop. This is not an emergency item on a well-maintained 2021+ example, but worth budgeting for on a high-mileage 2018-2020.

The 2.0T's 9-speed transmission benefits from early fluid changes. Forum consensus is to change the factory Dexron HP fluid at 45,000 miles rather than the OEM-recommended 60,000, which helps manage shudder onset.

FAQ Block

Is the 3rd gen Chevrolet Equinox reliable?

It depends on the year and powertrain. The 2021-2024 1.5T models are genuinely reliable: low NHTSA complaint counts, no recurring catastrophic failures, and known TSBs for the few documented issues. The 2018-2020 models, especially 2.0T versions, have documented 9-speed transmission shudder and higher complaint counts across every metric.

What year Chevrolet Equinox should I avoid?

Avoid 2018. It logged 362 NHTSA complaints in its first model year, the highest count in this generation. All three powertrains were new, and the 2.0T's 9-speed transmission shudder showed up immediately. If budget forces 2018-2020, skip the 2.0T option entirely and verify the charge air cooler recall is complete on 1.5T models.

What is the best year for a used 3rd gen Equinox?

The 2023. It is the only year before 2024 that combines the refreshed styling (2022+), above-average Consumer Reports reliability, and the switch to electric power-assisted braking that permanently eliminates the vacuum pump failure risk present on all 2018-2022 models. The 2022 gets the new look but has a 1/5 Consumer Reports reliability score — its worst in the generation. Start at 2023 if you can.

Does the Chevrolet Equinox burn oil?

The 1.5T (2018-2024) has documented oil consumption via piston ring wear and valve seal degradation. This is less severe than the 2.4L EcoTec issue that generated the 2010-2017 class action, but it is real. GM issued 20+ TSBs related to the 1.5T engine. At 40,000-60,000 miles, check the oil level carefully and ask for top-off records. An engine using less than a quart every 4,000-5,000 miles is manageable. Anything worse is a red flag.

How many miles does a 3rd gen Equinox last?

With proper maintenance, 150,000-200,000 miles is achievable. The 1.5T's known weaknesses (oil consumption, timing chain) can be managed with 7,500-mile synthetic oil changes and a timing chain inspection at 100,000 miles. Owners of 2021+ models with clean service records regularly report passing 100,000 miles without major repairs. The 2.0T's ceiling depends heavily on whether the 9-speed was serviced correctly.

Bottom Line

The 2023 Equinox LT or Premier is the buy. It is the only pre-2024 year that eliminates the vacuum pump failure chain with electric power brakes, has above-average Consumer Reports reliability, and carries the refreshed styling. Skip 2022 despite the new look — its 1/5 CR reliability score is real. Skip 2018-2020 unless you find a 1.5T-only car with Special Coverage N182202780 already performed and clean service records. Never buy a used 2.0T without doing the 25-30 MPH shudder test in person.

Run every VIN through a recall check before you go. The charge air cooler recall (N192271200) takes five minutes to verify and saves you from a stalling problem on the highway.

CarScout members can set alerts on specific years and trims to track price drops as they happen. Track the 2022 LT FWD — it is the best value combination in this generation and the inventory is deep. See what's available at usecarscout.com.
