📖Buick Encore I: pioneer urban luxury crossover requiring diligent cooling and PCV valve maintenance

Buick Encore I (2012-2017)

Introduced in late 2012 as Buick's first subcompact crossover, the Encore I delivered premium quietness and an elevated seating position within a tidy 4.28-metre footprint. Sharing its GM Gamma II platform with the Opel Mokka, it offered surprising cabin refinement and QuietTuning soundproofing. Keeping an Encore I dependable requires systematic Buick Encore maintenance, focusing heavily on engine cooling plastics and crankcase ventilation.

Under the stubby bonnet sits the 1.4-litre 1.4 Ecotec turbo (LUJ/LUV), paired with GM's 6T40 automatic gearbox in front or all-wheel drive. The primary mechanical headache involves the PCV valve system integrated into the intake manifold and cam cover, alongside fragile plastic cooling fittings including the water outlet housing and expansion tank.

Owner notes

The reassuring points, known weak spots and deadlines you should not let slip.

Reassuring points

Reliability
  • QuietTuning technology delivers impressive cabin silence unusual for a subcompact crossover.
  • Compact exterior footprint makes tight urban parking and city commuting effortless.
  • Affordable replacement parts shared broadly across GM and Opel platforms.

Chronic weak spots

Keep an eye on
  • PCV valve and camshaft cover: inspect for failed non-return check valve causing vacuum leaks and whistling.
  • Cooling system plastic pipes: check thermostat housing, water outlet tee and coolant tank for hairline cracks.
  • Turbocharger oil feed and coolant lines: check for oil baking on hot turbo lines causing burning oil smells.
  • 6T40 6-speed automatic gearbox: verify smooth shifting and check transmission fluid for burnt odour.
  • Front suspension top strut mounts: listen for clunking noises when turning the steering wheel at low speed.

Critical deadlines

Do not miss
  • Engine oil and filter change: renew every 8,000 to 10,000 km or 12 months with dexos1 synthetic oil.
  • Coolant hose and housing inspection: replace brittle plastic cooling fittings preventively around 100,000 km.
  • Transmission fluid renewal: drain and refill automatic transmission fluid every 50,000 to 60,000 km.
  • Brake fluid service: flush hydraulic fluid every 24 months to maintain braking performance.
