Engine-Related 2020 Chevrolet Equinox Problems and Fixes

The heart of your Equinox is its engine, and keeping it healthy is crucial. Let’s delve into specific engine-related issues and what you can do about them.

The 1.5L Turbo Oil Consumption Conundrum

The 2020 Equinox 1.5L Turbo engine oil consumption is a well-documented issue. It often stems from piston ring design or PCV system performance.

Symptoms include needing to add oil between scheduled changes, a burning oil smell, or even a blue tint to exhaust smoke.

Symptoms & Diagnostics

• Frequent Low Oil Levels: The most obvious sign is a dipstick reading consistently below the “full” mark, even after a recent oil change.
• Burning Oil Smell: Oil leaking onto hot engine components can produce a distinct burning odor.
• Check Engine Light: In severe cases, low oil pressure or catalyst damage from excessive oil burning can trigger the check engine light.

To diagnose, carefully monitor your oil level every 1,000 miles. Keep a log of how much oil you add. If you’re adding more than a quart every 3,000 miles, it’s worth further investigation.

Preventative Maintenance & Solutions

Using high-quality synthetic oil and adhering strictly to the manufacturer’s recommended oil change intervals (or even slightly shorter ones) can help.

Some owners have found relief with PCV valve replacements or more involved engine repairs if the piston rings are confirmed to be the culprit. Always consult a certified mechanic for definitive diagnosis and repair options, especially if you suspect significant oil consumption.

Timing Chain Wear

Another potential concern for some 2020 Equinox engines, particularly the 1.5L and 2.0L turbocharged variants, is premature timing chain stretch. This can lead to serious engine damage if ignored.

The timing chain synchronizes the crankshaft and camshafts, ensuring proper valve timing.

Symptoms of Timing Chain Stretch

• Engine Rattle or Whine: A distinct rattling or whining noise, especially on a cold start, can indicate a stretched timing chain. This noise may subside as the engine warms up.
• Check Engine Light: Mismatched timing signals can trigger diagnostic trouble codes (DTCs) related to camshaft or crankshaft position sensors.
• Reduced Engine Performance: Poor acceleration or rough idling might also be present.

Regular oil changes with the correct oil viscosity are crucial here. Dirty or low oil can starve the hydraulic tensioners that keep the timing chain tight.

Turbocharger Issues

Since both available engines for the 2020 Equinox are turbocharged, issues with the turbocharger system can arise. A common component to fail is the 2020 Equinox turbocharger wastegate actuator.

The wastegate controls exhaust flow to the turbo, regulating boost pressure.

Signs of Turbocharger Trouble

• Loss of Power: A noticeable decrease in acceleration or overall engine power, especially under load.
• Whining or Whirring Noise: Unusual sounds coming from the engine bay, particularly during acceleration.
• Check Engine Light: DTCs related to boost pressure or turbocharger performance will likely appear.
