What years did the Chevy Equinox have oil consumption problems?

The most consistently documented oil consumption problems in the Chevy Equinox affect two broad timeframes: the 2005–2009 first-generation models and the 2010–2017 second-generation models. These ranges have shown the highest volume of owner reports and technical public documentation.

Beyond those periods, reports exist but are less widespread. This article outlines the years most commonly cited, why the issue tends to surface, and what owners can do if they suspect excessive oil use. It also notes how GM has addressed the topic through service notices and coverage where applicable.

Generations and model-year ranges most associated with oil consumption

The following ranges summarize where owners have most frequently observed oil consumption concerns in the Equinox lineup.

• 2005–2009 Chevrolet Equinox (first generation) — commonly associated with oil consumption issues in the early, 3.4L V6-equipped models.


• 2010–2017 Chevrolet Equinox (second generation) — most frequently linked to oil consumption in the 2.4L four-cylinder engines, with occasional reports involving other engines in this generation.


• 2018–present Chevrolet Equinox (third generation) — far fewer widespread reports, but individual owners have continued to monitor oil usage, especially in models with new engine options.

If you own an Equinox from one of these years and you notice large increases in oil usage between changes, a dealership inspection is advisable to determine whether a service bulletin, repair, or warranty coverage applies.

What to look for and how to respond if you suspect oil consumption

To determine whether your Equinox is experiencing excessive oil consumption, use these steps as a practical guide.

• Monitor oil consumption between changes by comparing the amount of oil added to the engine with miles driven.


• Check for signs of rapid oil loss, such as frequent top-ups, smoke from the exhaust, or burning oil odor.


• Inspect for leaks or engine oil puddles under the vehicle and around gaskets, seals, and the PCV system.


• Ask a dealer to perform diagnostic checks if consumption is outside normal ranges, including an inspection of piston rings, valve seals, PCV system, and compression testing where appropriate.


• Inquire about GM service bulletins (TSBs) and any applicable warranty coverage for your year and engine combination. Coverage can vary by model year and region.


• Document maintenance history and keep receipts for oil purchases and any related repairs to support warranty or goodwill discussions with the dealer.

Early detection matters: excessive oil consumption can lead to engine damage if left unchecked. If you notice persistent oil loss, contact your local Chevrolet service center promptly.

GM guidance, recalls, and resources

General Motors has issued service information related to oil consumption for certain Equinox engines across various years. The guidance generally emphasizes checking for abnormal oil usage, applying any relevant service bulletins, and evaluating whether repairs are covered under warranty or extended coverage programs. Coverage and recommendations can differ by year, engine, and region, so it is important to reference the VIN-specific advisories at your local dealership or GM’s official recall/service pages.

Third-generation notes (2018–present)

With the move to newer turbocharged engines in the latest Equinox models, reports of widespread oil consumption are much less common than in the earlier generations. Owners should still follow normal maintenance intervals and report any unusual oil loss to a dealer, particularly if the vehicle is under warranty or an extended coverage program.

Summary

In the Chevrolet Equinox, oil consumption issues have been most prominently linked to two broad model-year spans: 2005–2009 (first generation) and 2010–2017 (second generation). While later generations have fewer documented widespread reports, individual cases do occur. If you own an Equinox from these periods and notice unusual oil loss, seek a prompt dealer evaluation, review any relevant service bulletins, and maintain thorough service records to determine eligibility for repairs or coverage.

What year was the bad year for Equinox?

Years to avoid for the Chevy Equinox are primarily 2010-2017, which were plagued by widespread engine problems like oil consumption, and earlier models like 2005-2008, which had lower reliability. For the third generation, the 2018 and 2022 models also stand out as problematic due to software issues and recalls. 
Years to avoid

• 2005-2008: These early models had numerous complaints and reliability issues compared to later years. 
• 2010-2017: This second generation is widely considered the least reliable due to significant engine problems, including excessive oil consumption, stalling, and timing chain failures, especially with the 2.4-liter four-cylinder and 3.0-liter V6 engines. 
• 2018: This model year had software issues that would cause the check engine light to come on unnecessarily. 
• 2022: This year was affected by multiple recalls for issues like seat-bolt, fuel-pump, and child-seat anchors. 

Years to consider (with caution)

• 2009: Considered the best of the first generation, as the final year fixed some earlier flaws and added safety features. 
• 2014-2017: While still part of the problematic second generation, these years had fewer oil consumption issues than earlier years in that period. The V6 and newer turbocharged engines from later generations are more reliable than the 2.4L four-cylinder option. 
• 2019-2021 & 2023: These are generally considered better years for the third generation, but be aware of some recalls and other complaints that still occurred during this time. 
• 2024: This is a final model year for the current generation, and while it may be affordable, some sources note it as unrefined and underpowered with its base 1.5L engine. 
• 2025: This marks the start of the fourth generation and some sources suggest it may not have fixed many of the issues from previous years, making it a potentially weaker option compared to other SUVs on the market. 

What year does Equinox have oil consumption problems?

This letter is intended to make you aware that some 2012 model year Chevrolet Equinox or GMC Terrain vehicles, equipped with a 2.4L engine, may exhibit excessive engine oil consumption (less than 2,000 miles [3,200 km] per quart [0.946 L] of engine oil), due to piston ring wear.

Why is my Chevy Equinox burning oil so fast?

Your Chevy Equinox is likely burning oil fast due to a common problem with the 2.4L engine involving worn piston rings and potentially a clogged Positive Crankcase Ventilation (PCV) system. This allows oil to seep past the pistons and into the combustion chamber where it is burned off, often leading to excessive oil consumption and sometimes blue exhaust smoke. 
Common causes for your Equinox

• Worn piston rings: This is the most frequent cause for excessive oil consumption in these models. Low-tension oil rings can fail to prevent oil from entering the combustion chamber. 
• Clogged PCV system: A plugged up PCV valve or the small orifice within the intake can create excessive crankcase pressure, forcing oil past seals and rings. 
• Engine age: As engines age, wear and tear can lead to internal components like piston rings and seals becoming worn, increasing oil consumption. 

What you should do

1. Diagnose the problem:
   • Check for blue exhaust smoke, which is a key indicator of oil being burned. 
   • Inspect the PCV valve to see if it's clogged, as this is a common and relatively inexpensive fix. 
2. Address the issue:
   • If the PCV system is the cause, cleaning or replacing the valve can help. 
   • If the issue is due to worn piston rings, it is a more significant repair that may require a full engine overhaul or replacement. 
3. Consider your vehicle's history:
   • If your vehicle is within the extended warranty period for this issue, you may be eligible for a free repair from a Chevrolet dealer. 
   • Be aware that General Motors has had past issues and class-action lawsuits regarding this problem, which may offer further recourse. 

Disclaimer: A mechanic should perform any diagnosis or repair work to ensure your vehicle is properly serviced.

What is the lawsuit for oil consumption on Chevy Equinox?

A large class action settlement was approved for Chevy Equinox models with defective 2.4L engines that caused excessive oil consumption, with potential for owners to receive a share of a $150 million fund. The lawsuits allege the issues stem from defective piston rings, leading to premature engine wear and failure. Some model years, particularly 2010–2017, are involved, but the settlement specifics and eligibility can vary by state.
 
What the lawsuit is about

• Engine defect: The central claim is that the 2.4L Ecotec engines in certain model years have defective piston rings that wear out prematurely, causing excessive oil consumption.
