The 2018 Equinox BR (third-gen) represents a complete redesign with turbocharged engines that have shown pattern failures in critical internal components. The 1.5T is particularly problematic with timing chain and lifter issues emerging surprisingly early, while both engines share cooling and valvetrain concerns that can lead to catastrophic damage if ignored.
1.5T Timing Chain Stretch and Guide Failure
Common · high severityTypical onset: 60,000-100,000 mi
Symptoms: Cold-start rattle lasting 3-5 seconds, Check engine light with P0016/P0017 cam/crank correlation codes, Rough idle that smooths out when warm, Metallic rattling on acceleration
Fix: Complete timing chain kit replacement including guides, tensioner, and both VVT solenoids. Requires front cover removal. 8-10 hours labor. Often discover worn cam phasers during teardown adding 2-3 hours.
Estimated cost: $2,200-3,800
VLOM (Variable Valve Lifter Oil Manifold) and Lifter Failure - 1.5T
Common · high severityTypical onset: 70,000-120,000 mi
Symptoms: Ticking/tapping noise that persists after warm-up, P0300 random misfire with P0201-P0204 injector codes, Loss of power on acceleration, Engine shakes at idle, Metal shavings in oil during changes
Fix: Requires cylinder head removal to replace all lifters, VLOM assembly, and resurface head if damage present. Often combined with timing chain job if chain is marginal. 12-16 hours labor for lifters alone, 18-22 if head needs machine work.
Estimated cost: $3,500-6,500
Transmission Oil Cooler Line Leaks (9-speed)
Common · medium severityTypical onset: 40,000-80,000 mi
Symptoms: Transmission fluid puddles under vehicle near radiator, Pink/red fluid dripping, Delayed engagement when cold, Transmission slipping or shuddering if fluid level drops
Fix: Replace transmission cooler lines where they connect to radiator. Lines corrode at crimp points. 2-3 hours labor including fluid top-off and leak check. Sometimes requires radiator removal for access.
Estimated cost: $400-750
Carbon Buildup on Intake Valves (Both Turbo Engines)
Occasional · medium severityTypical onset: 80,000-120,000 mi
Symptoms: Rough idle and misfires, Reduced fuel economy (3-5 mpg drop), Hesitation on acceleration, P0300-P0304 misfire codes, Failed emissions testing in some states
Fix: Direct injection engines have no fuel wash on intake valves. Requires walnut shell blasting through intake manifold. 4-5 hours labor. Preventive service, not a parts failure, but becomes necessary.
Estimated cost: $500-800
2.0T High-Pressure Fuel Pump Failure
Occasional · high severityTypical onset: 60,000-90,000 mi
Symptoms: Hard starting or extended cranking, Stumbling and stalling under load, P0087 fuel pressure too low code, Loud ticking from engine bay, Limp mode activation
Fix: High-pressure fuel pump (mechanical, cam-driven) fails internally. Requires camshaft cover removal and timing alignment. 3-4 hours labor. Critical to check for metal contamination in fuel system.
Estimated cost: $1,200-1,800
Transmission Mount Failure (Both Engines)
Occasional · low severityTypical onset: 50,000-90,000 mi
Symptoms: Clunk when shifting from park to drive or reverse, Vibration at idle in gear, Excessive engine movement visible when revving, Harsh engagement into gear
Fix: Upper transmission mount (torque strut) tears at rubber isolator. Requires support of powertrain. 1.5-2 hours labor. Inspect all motor mounts while there.
Estimated cost: $250-450
PCV System Failure Leading to Oil Consumption
Occasional · medium severityTypical onset: 50,000-100,000 mi
Symptoms: Burning 1 quart per 1,000-2,000 miles, Blue smoke on cold start, Oil in intake tube and throttle body, P0171/P0174 lean codes from unmetered air
Fix: Integrated valve cover with built-in PCV must be replaced as assembly. Cannot service individual components. 2-3 hours labor. Check for clogged ports in head during replacement.
Estimated cost: $600-1,000
Hard pass on the 1.5T unless under warranty or priced $3,000-4,000 below market to cover inevitable engine work; 2.0T is slightly better but still a gamble—both engines rushed to market with inadequate development time.
