📖Buick Regal V saloon: European-bred sports saloon demanding strict timing chain and turbo care

Buick Regal V Sedan (2009-2013)

Adapted directly from the European Opel/Vauxhall Insignia on GM's Epsilon II platform, the fifth-generation Buick Regal marked a radical departure for the nameplate, trading soft suspension for firm, communicative German chassis dynamics. The flagship Regal GS added Brembo front brakes, 19-inch wheels and HiPer Strut front suspension. Sustaining this athletic saloon requires dedicated Buick Regal maintenance, focusing on timing chain upkeep and direct-injection fuel systems.

Powertrains comprised the 2.4-litre naturally aspirated Ecotec and the potent 2.0-litre 2.0T Ecotec turbo (220 to 270 hp on the GS), mated to a 6-speed manual or 6-speed 6T70 automatic. Both engines utilise a timing chain system vulnerable to stretch if engine oil is neglected. High-pressure direct-injection fuel pumps and camshaft actuators also require monitoring.

Owner notes

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

Reassuring points

Reliability
  • European-engineered chassis delivering taut cornering composure, sharp steering and motorway stability.
  • Punchy 270 hp 2.0T engine in the GS offering spirited acceleration and strong mid-range pull.
  • Handsome exterior proportions with sculpted European lines and high-quality cabin appointments.

Chronic weak spots

Keep an eye on
  • Timing chain and tensioners: inspect for cold-start rattle; change engine oil frequently to prevent chain stretch.
  • Variable valve timing (VVT) solenoids: check for camshaft correlation trouble codes and oil sludge.
  • High-pressure fuel pump (HPFP): monitor for ticking noise and inspect for fuel dilution in engine oil.
  • 6-speed automatic transmission: check for shift flares or harsh downshifts in stop-and-go traffic.
  • HiPer Strut suspension on GS: inspect ball joints and bushes for wear causing front-end knocking.

Critical deadlines

Do not miss
  • Engine oil and filter change: renew every 8,000 to 10,000 km or 12 months with dexos1 Gen 3 oil.
  • Automatic transmission service: drain and refill transmission fluid every 60,000 km.
  • Brake fluid service: flush hydraulic fluid every 24 months to maintain firm pedal feel.
  • Spark plug replacement: renew iridium spark plugs every 60,000 km on 2.0T turbo engines.
