2012 Buick Regal Recalls, Issues & Maintenance

The 2012 Buick Regal carries 7 open NHTSA recalls — most recently covering power adjust and turn signal. Owners report 6 recurring issue clusters, led by “Headlight assembly condensation and water intrusion.” Buick uses the GM Oil Life System: an algorithm tracks engine revolutions and temperature, then lights the change-oil message — typically every 7,500 miles in mixed driving, capped at 12 months, using dexos-approved oil. Current Encore GX and Envista run 1.2/1.3L turbo three-cylinders where oil quality matters more than volume drivers expect (the sump is small and turbo-heated). Front-drive models pair to a CVT with a published fluid interval — it is not a lifetime part.

SEATS:FRONT ASSEMBLY:POWER ADJUST

Campaign #14V447000 · Jul 23, 2014

Issue: General Motors LLC (GM) is recalling certain model year 2011-2012 Buick LaCrosse, Regal and Chevrolet Camaro, as well as certain 2010-2012 Cadillac SRX, Chevrolet Equinox and GMC Terrain vehicles, equipped with power height adjustable driver and passenger seats. In the affected vehicles, the bolt that secures the driver's and passenger's power front seat height adjuster may fall out causing the seat to drop suddenly to the lowest vertical position.

Risk: If the driver's seat unexpectedly drops, the distraction and altered seat position may affect the drivers' control of the vehicle, increasing the risk of a crash.

Fix: GM will notify owners, and dealers will replace the height adjuster shoulder bolts, free of charge. The manufacturer distributed interim letters to owners on September 11, 2014. The recall began on December 26, 2014. Owners may contact GM customer service at 1-800-521-7300 (Buick), 1-800-458-8006 (Cadillac), 1-800-222-1020 (Chevrolet), or 1-800-462-8782 (GMC). GM's number for this recall is 14271.

EXTERIOR LIGHTING:TURN SIGNAL

Campaign #12V484000 · Apr 10, 2012

Issue: General Motors LLC (GM) is recalling certain model year 2011-2013 Buick Regal and model year 2013 Chevrolet Malibu vehicles. These vehicles are equipped with two turn signal bulbs in each front turn signal. If one of the two front turn signal bulbs burn out in either front turn signal lamp, there is no indication to the driver. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard No. 108, "Lamps, Reflective Devices, and Associated Equipment."

Risk: If the driver is not aware that a turn signal is not functioning properly, the driver may continue to drive the vehicle. If half of a front turn signal is not illuminating, other driver's may not be aware that the affected vehicle is turning, thereby increasing the risk of a crash.

Fix: GM will notify owners, dealers will update the body control module software, free of charge. The recall began in September 2014. Owners may contact Buick at 1-800-521-7300 or Chevrolet at 1-800-222-1020. GM's number for this recall is 12212.

EXTERIOR LIGHTING

Campaign #12V093000 · Jul 3, 2012

Issue: GENERAL MOTORS (GM) IS RECALLING CERTAIN MODEL YEAR 2012 BUICK REGAL VEHICLES MANUFACTURED FROM FEBRUARY 22, 2011, THROUGH FEBRUARY 22, 2012 FOR FAILING TO COMPLY WITH THE REQUIREMENTS OF FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 108 “LAMPS, REFLECTIVE DEVICES AND ASSOCIATED EQUIPMENT.” DUE TO A SOFTWARE ERROR, THE PARKING LAMPS DO NOT ACTIVATE WHEN EITHER THE PARKING LAMPS OR HEADLAMPS ARE TURNED ON.

Risk: INADEQUATE LIGHTING COULD REDUCE THE VISIBILITY OF THE VEHICLE, INCREASING THE POTENTIAL FOR A CRASH.

Fix: GENERAL MOTORS WILL NOTIFY OWNERS, AND DEALERS WILL REPROGRAM THE BODY CONTROL MODULE FREE OF CHARGE. THE SAFETY RECALL BEGAN ON MARCH 29, 2012. OWNERS MAY CONTACT GM AT 1-800-521-7300.

ELECTRICAL SYSTEM

Campaign #13V173000 · Jun 5, 2013

Issue: General Motors (GM) is recalling certain model year 2012 and 2013 Buick LaCrosse and Regal, and model year 2013 Chevrolet Malibu Eco vehicles equipped with eAssist. These vehicles may have a condition in which the Generator Control Module (GCM) may not function properly. This could cause a gradual loss of battery charge and the illumination of the malfunction indicator light.

Risk: If the vehicle is continued to be driven, the engine may stall and/or the vehicle may not start. In addition, there may be a burning or melting odor, smoke, and possibly a fire in the trunk.

Fix: GM will notify owners and dealers will test the GCM and replace it, as necessary, free of charge. The recall began on June 11, 2013. Owners may contact GM at 1-800-521-7300. GM's recall campaign number is 13136.

SUSPENSION:REAR

Campaign #20V764000 · Dec 21, 2020

Issue: General Motors, LLC (GM) is recalling certain 2012-2013 Buick Regal, 2013 Chevrolet Malibu, and 2010-2013 Buick Lacrosse vehicles sold or ever registered in Connecticut, Delaware, the District of Columbia, Illinois, Indiana, Iowa, Kentucky, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, Virginia, West Virginia, or Wisconsin. These vehicles may have rear toe links that received excessive electrocoating (e-coat) corrosion protection, which could cause the e-coat to become brittle and break away when contacted by road debris. Over time, the e-coat may chip away, exposing the metal toe link and making it more susceptible to corrosion. Corrosion may eventually cause the toe link to thin and ultimately to fracture.

Risk: A rear toe link fracture may reduce the driver's ability to control the vehicle, increasing the risk of a crash.

Fix: GM will notify owners, and dealers will replace the rear suspension toe links and adjuster fasteners free of charge. Parts are not currently available. Owners were mailed an interim notification on January 27, 2021, and April 15, 2021. A third notification was mailed on August 19, 201. Owners may contact Buick customer service at 1-800-521-7300 or Chevrolet customer service at 1-800-222-1020. GM's number for this recall is N202308930.

Issue: General Motors, LLC (GM) is recalling certain 2010-2013 Buick Lacrosse, 2012-2013 Buick Regal, and 2013 Chevrolet Malibu vehicles sold or ever registered in Connecticut, Delaware, the District of Columbia, Illinois, Indiana, Iowa, Kentucky, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, Virginia, West Virginia, or Wisconsin. These vehicles may have rear toe links that received an improper amount of electrocoating (e-coat) corrosion protection, which could cause the e-coat to become brittle and break away when contacted by road debris. Over time, the e-coat may chip away, exposing the metal toe link and making it more susceptible to corrosion. Corrosion may eventually cause the toe link to thin and ultimately fracture.

Risk: A rear toe link fracture may reduce the driver's ability to control the vehicle, increasing the risk of a crash.

Fix: Dealers will replace the rear suspension toe links and adjuster fasteners, free of charge. Owner notification letters were mailed January 27, 2022. Owners may contact Buick customer service at 1-800-521-7300 or Chevrolet customer service at 1-800-222-1020. GM's number for this recall is N212346640.

Essential maintenance

Critical for safety and preventing major damage

Engine Oil & Filter (Oil Life System)

Every 7,500 mi

Change when the Oil Life System calls it — typically around 7,500 miles, never beyond 12 months. dexos1 0W-20 on modern engines. Small-displacement turbos (Encore GX, Envista): don't stretch the indicator.

Estimated cost — typical U.S. ranges

Dealer

~$120–$160

Shop

~$85–$115

DIY

~$25–$55

Full synthetic costs more than conventional. 5-quart 0W-20 + filter is the typical bill.

Tire Rotation

Every 7,500 mi

Rotate every 7,500 miles with the oil change — GM pairs the two in its schedule.

Estimated cost — typical U.S. ranges

Dealer

~$85

Shop

~$60

DIY

Free

Often free at the shop where you bought the tires — worth asking before paying.

Brake Inspection

Every 7,500 mi

Inspect pads, rotors, and lines at every service. Older Centurys: check rear drum adjustment and parking-brake cables, which seize with age.

Estimated cost — typical U.S. ranges

Dealer

~$85

Shop

~$60

DIY

Free

Most shops do this free as a courtesy with any service. Don't pay separately if you can avoid it.

CVT Fluid (Encore GX / Envista FWD)

Every 45,000 mi

FWD Encore GX and Envista use a CVT: GM schedules fluid replacement around 45,000 miles under severe service — which includes most city commuting. AWD Encore GX uses a 9-speed automatic instead (see transmission fluid).

Estimated cost — typical U.S. ranges

Dealer

~$360–$500

Shop

~$255–$355

DIY

~$80–$180

CVT fluid is manufacturer-specific and pricey — do NOT substitute conventional ATF.

Important maintenance

Keeps your vehicle running smoothly and efficiently

Automatic Transmission Fluid

Every 45,000 mi

Conventional automatics (Century's 4T65-E, Regal's Aisin, AWD Encore GX's 9-speed): GM lists 45,000 miles severe / longer normal. Older Buicks respond well to a simple drain-and-fill — avoid pressure flushes on high-mile units.

Estimated cost — typical U.S. ranges

Dealer

~$330–$500

Shop

~$235–$355

DIY

~$60–$180

Some sealed transmissions have no dipstick — fill is precise and best left to a shop. Many drivers can still DIY drain-and-fill.

Spark Plugs

Every 60,000 mi

Small-turbo three-cylinders (Encore GX, Envista): roughly every 60,000 miles — check the manual. Older 3.1/3.8 V6s: iridium plugs last to 100,000 miles.

Estimated cost — typical U.S. ranges

Dealer

~$285–$390

Shop

~$200–$275

DIY

~$25–$100

Iridium plugs cost more but last 100k+ miles. V6/V8 access varies wildly — some are tough.

Engine Air Filter

Every 45,000 mi

GM schedules replacement around 45,000 miles; inspect at every oil change in dusty regions.

Estimated cost — typical U.S. ranges

Dealer

~$60–$95

Shop

~$45–$70

DIY

~$15–$40

5-minute job on most cars; the airbox lid usually has clips, no tools needed.

Serpentine Belt

Every 60,000 mi

Inspect from 60,000 miles; replace on cracking or glazing rather than mileage alone.

Estimated cost — typical U.S. ranges

Dealer

~$195–$235

Shop

~$135–$165

DIY

~$20–$50

DIY-friendly if you can reach the tensioner. Inspect for cracks rather than swap on a strict mileage interval.

Recommended maintenance

Extends the life of your vehicle and improves comfort

Cabin Air Filter

Every 22,500 mi

Replace roughly every 22,500 miles per GM's schedule — behind the glovebox on modern Buicks.

Estimated cost — typical U.S. ranges

Dealer

~$60–$95

Shop

~$45–$70

DIY

~$15–$40

Usually behind the glovebox. Shops charge labor for a 10-minute job — easy DIY win.

Coolant Replacement (Dex-Cool)

Every 150,000 mi

Dex-Cool is rated 5 years / 150,000 miles. On older 3.1/3.8 V6s, intake-gasket seepage was the classic failure — check coolant level and condition at every oil change on a Century.

Estimated cost — typical U.S. ranges

Dealer

~$285–$330

Shop

~$200–$235

DIY

~$25–$60

Use the manufacturer-specified coolant — wrong color/chemistry can damage the cooling system.

Battery Test & Service

Every 25,000 mi

Test annually after year 3. Stop-start-equipped Encore GX/Envista use AGM batteries — replace like-for-like, not with a cheaper flooded battery.

Estimated cost — typical U.S. ranges

Dealer

~$225–$390

Shop

~$160–$280

DIY

~$130–$250

Most auto-parts stores test and install batteries free with purchase. Skip the dealer markup.

Fatal crash history & reported problems

Occupant deaths in fatal crashes (FARS)
