2020 Chevy Equinox Problems: Known Issues by Mile

⚡ The short answer

Known issues, but not a lemon. The 2020 Chevy Equinox is a mid-pack compact SUV with one headline weakness: the 1.5L turbo four can burn oil. Most other complaints (infotainment freezes, AC leaks, a balky 9-speed) are nuisance-grade and fixable. Buy one with records, verify oil consumption, and you have a solid family hauler.

The 2020 model year is a meaningful step up from the rocky 2018 redesign. Recalls have been modest in scope compared to the launch years, and the second-generation platform had several years to mature. But "better" is not "perfect." The single most-reported 2020 Chevy Equinox problem is excessive oil consumption on the 1.5L turbo (GM engine code LYX), and it is the one issue that can turn a $5,000 used SUV into a $9,000 mistake if you ignore it.

Below we rank the problems by how frequently owners report them, show the mileage band where each tends to surface, and give honest repair-cost ranges so you can tell a $200 fix from a four-figure one.

📊 Most-reported problems, ranked

Rankings reflect the relative frequency of owner complaints and shop reports for the 2020 model year. Costs are typical independent-shop ranges in the US and will run higher at a dealer.

Problem	Typical Mileage	Repair Cost	Severity
1.5L turbo oil consumption	50k–90k	$300 (PCV) to $3,000–$6,000 (rings)	High
Infotainment freeze / reboot	20k–60k	$0 (reflash) to $900 (unit)	Low
AC condenser / refrigerant leak	40k–80k	$500–$1,100	Medium
9-speed harsh / hesitant shift	30k–70k	$0–$200 (flush/reflash)	Low
Stop/start & battery drain	25k–60k	$200–$450 (battery)	Low
Emissions / EVAP code (P0455)	40k–90k	$20 (cap) to $350 (purge valve)	Low

🔧 The breakdown, one by one

1. Oil consumption on the 1.5L turbo (the big one)

The 1.5L turbocharged four-cylinder is the base engine in most 2020 Equinox trims, and its appetite for oil is the defining 2020 Chevy Equinox problem. Owners commonly report losing about one quart every 1,500 to 3,000 miles, with the symptom often appearing after 50,000 miles. GM's official tolerance is roughly one quart per 2,000 miles, which means a dealer can call real consumption "normal." Causes range from a sticking PCV system (cheap) to worn or carbon-stuck piston rings (expensive). If you see oil-soaked spark plugs, a low cylinder on a compression test, or blue smoke on startup, assume the rings.

2. Infotainment freezes and reboots

The Chevrolet Infotainment 3 system on the 2020 Equinox can freeze, drop Apple CarPlay or Android Auto, or reboot mid-drive. It is annoying but almost never a safety issue. Many cases clear with a software reflash at the dealer at no cost, or a battery-disconnect reset you can do yourself. A full head-unit replacement is the rare worst case.

3. AC condenser and refrigerant leaks

Weak air conditioning that gradually stops getting cold is a recurring complaint, usually traced to a condenser leak. Expect $500 to $1,100 for a condenser replacement and recharge. If the AC blows warm and you live somewhere hot, treat this as a priority inspection item. See our AC not blowing cold guide for how to diagnose it before you buy.

4. 9-speed transmission shift quality

The optional 9-speed automatic (paired with the 2.0L turbo) and the 6-speed on the 1.5L are both reasonably durable. Complaints center on harsh, hesitant, or shuddery low-speed shifts rather than outright failure. A fluid flush or a software reflash resolves most of them. If you feel actual slipping, get a scan before you commit.

5. Stop/start and battery drain

The auto stop/start system stresses the 12-volt battery, and some owners replace batteries earlier than expected, around 25,000 to 60,000 miles. A parasitic drain can also leave you with a no-start. A fresh AGM battery is usually the cure. If you keep getting dead batteries, scan for a P0455 or other module-related codes that hint at something staying awake.

⚠️ What to watch before you buy or fix

If you are shopping for a used 2020 Equinox or deciding whether to keep yours, run through this list. Most of these checks take ten minutes and can save you thousands.

Verify oil consumption. Ask for service records. Check the dipstick. If the seller "tops it off," ask how often and how much. One quart per 2,000 miles or worse is a red flag.
Pull the spark plugs or ask the shop. Oil-fouled plugs on the 1.5L point straight at the rings.
Scan for codes. A quick OBD2 scan reveals stored EVAP, misfire, or transmission codes the seller may have cleared. Our check engine light guide walks through reading them.
Test the AC cold. Run it on max for five minutes and feel the vent temperature.
Drive it slow and in traffic. That is where 9-speed and 6-speed shift complaints show up, not on the highway.
Check open recalls by VIN. Enter the VIN at the NHTSA recall lookup to confirm any safety campaigns were completed.

🎯 Dealbreaker or negotiate? A quick framework

Not every problem on this page should scare you off. Here is how to sort them.

Walk away from: Heavy oil consumption paired with low compression, fouled plugs, or startup smoke. That is a rings job, which means $3,000 to $6,000 or a full engine. Unless there is active warranty or bulletin coverage, the math rarely works on a used SUV.

Negotiate the price on: AC condenser leaks ($500–$1,100), a battery that is on its way out ($200–$450), and persistent infotainment glitches. These are known, bounded costs. Get a quote, then knock it off the asking price.

Live with: Occasional infotainment reboots, a minor shift hesitation that a flush fixes, and EVAP codes from a loose gas cap. These are nuisance-grade and cheap or free to address.

Before you accept any shop estimate on the engine or transmission, sanity-check it with our repair quote checker so you know whether the number is fair for your area.

❓ FAQ

Is the 2020 Chevy Equinox a reliable SUV?

It is mid-pack. The 2020 Equinox is more dependable than the troubled 2018 launch year, but the 1.5L turbo engine still has a known appetite for oil, and infotainment glitches are common. Buy a well-maintained example with service records and budget for the oil-consumption check around 60,000 to 90,000 miles.

Does the 2020 Equinox burn oil?

Yes, the 1.5L turbo four (LYX engine) is the most-reported issue. Owners report consumption of roughly one quart every 1,500 to 3,000 miles, often surfacing after 50,000 miles. GM considers up to one quart per 2,000 miles within spec, so document your numbers before a dealer visit.

How much does it cost to fix the 2020 Equinox oil consumption problem?

It depends on the cause. PCV-related fixes run a few hundred dollars. If the piston rings are at fault, a partial or full engine teardown can run $3,000 to $6,000 or more. Check for any active warranty extension or service bulletin coverage first, because that can make the repair free.

Which 2020 Equinox problem is a dealbreaker?

Heavy oil consumption with low compression or fouled plugs is the one to walk away from, because it points at the rings and a four-figure engine job. Infotainment freezes, AC condenser leaks, and a balky 9-speed shift are annoying but fixable and should be price-negotiation items, not walk-aways.

Does the 2020 Equinox have transmission problems?

The 6-speed and 9-speed automatics are generally durable, but some owners report harsh or hesitant shifts and a shudder at low speed. Many cases are resolved with a transmission fluid flush or a software reflash rather than a rebuild. Persistent slipping is rarer and worth a pre-purchase scan.

📝 TL;DR

The 2020 Chevy Equinox is a reasonable used buy with one issue that demands attention: 1.5L turbo oil consumption, which can cost anywhere from $300 to $6,000 depending on the root cause. Everything else (infotainment, AC, shift quality, battery) is fixable and should be a price-negotiation lever, not a deal-killer. Verify oil burn, scan for codes, and test the AC cold before you sign.
