The 2021 Equinox with the 1.5L turbo is a third-generation compact crossover showing familiar GM small-turbo weaknesses. The engine's timing-chain and lifter issues appear earlier than acceptable, while the nine-speed automatic sees cooler and fluid-related failures that suggest inadequate factory service intervals.
Timing Chain Stretch and Guide Wear
Common · high severity
Typical onset: 60,000-100,000 mi
Symptoms: Cold-start rattle for 2-3 seconds then goes away, Check engine light with P0016 cam/crank correlation codes, Rough idle that improves when warm, Occasional stalling or no-start conditions in severe cases
Fix: Timing chain, guides, tensioner, and both VVT solenoids. Front engine disassembly required. 8-10 hours labor depending on access and whether you're doing lifters at the same time, which many techs recommend since you're already in there.
Estimated cost: $1,800-3,200
Lifter Collapse / VLOM System Failure
Common · medium severity
Typical onset: 50,000-90,000 mi
Symptoms: Ticking or tapping noise from valve cover area, P0300-series misfire codes with no other clear cause, Reduced power on acceleration, Noise worsens with low oil or extended oil-change intervals
Fix: Replace all lifters plus VLOM solenoid assembly. Cylinder head removal required, often combined with timing chain job if it's already showing wear. Add valve lash inspection and potential cam wear check. 10-14 hours if standalone, less if piggybacking on timing chain work.
Estimated cost: $2,200-4,000
Transmission Oil Cooler Line Leaks
Occasional · medium severity
Typical onset: 40,000-80,000 mi
Symptoms: Transmission fluid puddles under vehicle front-center, Low fluid warning light or message, Harsh shifting when fluid drops below minimum, Smell of burnt ATF if driven low
Fix: Replace cooler lines and often the external cooler itself since corrosion is usually systemic. 2-3 hours labor. Requires full fluid exchange afterward, and many shops recommend replacing the internal filter while fluid is out.
Estimated cost: $600-1,100
Transmission Mount Failure
Occasional · low severity
Typical onset: 60,000-100,000 mi
Symptoms: Clunk on shifts from park to drive or reverse, Vibration at idle in gear, Excessive engine movement visible when revving in park, Torque steer or steering wheel vibration on acceleration
Fix: Replace upper transmission mount. Simple job but requires supporting the engine/trans. 1.5-2 hours labor. Check lower mount at the same time—if one's failed, the other is stressed.
Estimated cost: $250-450
Turbocharger Wastegate Rattle
Occasional · low severity
Typical onset: 50,000-120,000 mi
Symptoms: Rattling or buzzing sound on light throttle around 1,500-2,500 RPM, No loss of power in most cases, Sound diminishes under harder acceleration, May throw P0234 overboost code if actuator sticks
Fix: Turbo wastegate actuator arm wears or actuator itself fails. Replacement turbo is the permanent fix, though some techs have success with actuator recalibration if caught early. 4-6 hours labor for turbo replacement.
Estimated cost: $1,200-2,200
PCV System Clogging and Oil Consumption
Common · medium severity
Typical onset: 40,000-80,000 mi
Symptoms: Consuming a quart of oil every 1,500-3,000 miles, Blue smoke on startup, Rough idle with P0171/P0174 lean codes, Oil in intake tract or throttle body
Fix: Replace PCV valve and clean intake manifold. Inspect valve cover for cracks—some '21s had bad batches. If oil consumption persists, valve stem seals or piston rings are suspect. PCV service alone is 1-2 hours; full valve cover and seals job adds significantly.
Estimated cost: $300-600 for PCV system, $1,500-2,800 if seals needed
Owner tips
Change oil every 5,000 miles maximum with quality synthetic—these engines do NOT tolerate 7,500-mile intervals despite what the manual says, especially if you want lifters to survive
Service the nine-speed transmission fluid at 50,000 miles even though GM calls it 'lifetime'—cooler contamination and clutch wear demand earlier changes
Listen for cold-start rattle and address timing chain at first sign; delaying risks jumped timing and valve contact
Check oil level every other fillup—half a quart low is enough to starve lifters on hard cornering
Buy only if under 40,000 miles with full service records and budget $2,000-3,000 for eventual timing chain and lifter work—it's when, not if.

General Motors, LLC (GM) is recalling certain 2020-2023 Chevrolet Equinox and GMC Terrain vehicles. The four rear-seat lower child seat LATCH anchorage bars may have excessive powder coating, which could prevent a child seat from being installed with the anchorage bars. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 225, "Child Restraint Anchorage Systems."
Consequence: The inability to install a child seat with the LATCH anchorage bars could result in an unsecured child seat, increasing the risk of injury in a crash.
Remedy: Owners are advised to install child seats using the vehicle's rear seat belts until the remedy is complete. Dealers will inspect the latch anchorage bars, and remove and replace the finish, as necessary, free of charge. Owner notification letters were mailed June 2, 2023. Owners may contact Chevrolet customer service at 1-800-222-1020 or GMC customer service at 1-800-462-8782. GM's number for this recall is N232403240.
