NHTSA's VIN data lists these trims for the 2012 Sonic. A trim's engine and numbers are shown as its own only where EPA names versions after the trim and no other version could be it; "seen with" means a source shows that engine on the trim, not that it was the only one. Recalls and complaints cover the whole model year: whether a recall applies to a car depends on its VIN, on NHTSA's recall lookup.
Owners have filed 354 complaints with NHTSA about the 2012 Sonic. These are unverified owner reports, counted by the part of the car they name; one complaint can name several parts. Counts aren't adjusted for how many were sold, so they don't show how reliable a car is.

Complaints by model year
Newer years have had less time to collect complaints, and counts aren't adjusted for sales, so a shorter bar doesn't mean a more reliable year.
NHTSA lists 7 recall campaigns for the 2012 Sonic over its history. Campaigns are matched by model and year, so each one may apply to a given car, and its repair may already be done: check a VIN on NHTSA's recall lookup for the open recalls on that exact car.
General Motors LLC (GM) is recalling certain model year 2013-2014 Buick Encore all-wheel-drive vehicles manufactured August 23, 2012, to September 9, 2013; Verano vehicles manufactured August 8, 2012, to June 20, 2013; Chevrolet Cruze vehicles manufactured August 7, 2012, to August 16, 2013, and 2012-2014 Chevrolet Sonic vehicles manufactured May 10, 2011, to August 16, 2012 equipped with a Calix oil pan/block heater. In cold temperatures, the insulation on the engine block heater cord can become damaged, allowing the wires to be exposed.
Risk: Exposed wires increase the risk of electrical shock and personal injury if the cord is handled while it is plugged in.
Remedy: GM will notify owners, and dealers will replace the engine oil pan/block heater cord with a new cord that is rated for temperatures of minus 40 degree Celsius. The recall began in August 2014. 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 14257.
General Motors LLC (GM) is recalling certain model year 2012 Chevrolet Sonic vehicles manufactured March 1, 2012, to June 29, 2012, and equipped with a 6 speed automatic transmission and 1.8L four cylinder engine. In the affected vehicles, the transmission turbine shaft may fracture.
Risk: If the transmission turbine shaft fracture occurs during vehicle operation in first or second gear, the vehicle will not upshift to the third through sixth gears, limiting the vehicle's speed. If the fracture occurs during operation in third through sixth gear, the vehicle will coast until it slows enough to downshift to first or second gear, increasing the risk of a crash.
Remedy: GM will notify owners, and dealers will replace the transmission turbine shaft, free of charge. The recall began on August 8, 2014. Owners may contact Chevrolet customer service at 1-800-222-1020. GM's number for this recall is 14234.
General Motors LLC (GM) is recalling certain model year 2012 Buick Verano vehicles manufactured December 2, 2011 to July, 16, 2012, Chevrolet Cruze vehicles manufactured December 7, 2011 to July 25, 2012, Chevrolet Sonic vehicles manufactured December 5, 2011 to August 2, 2012, and Chevrolet Camaro vehicles manufactured December 1, 2011 to June 11, 2012. The driver side frontal air bag has a shorting bar which may intermittently contact the air bag terminals.
Risk: If the bar and terminals are contacting each other at the time of a crash necessitating deployment of the driver's frontal air bag, that air bag will not deploy, increasing the driver's risk of injury.
Remedy: GM will notify owners, and dealers will replace the steering wheel air bag coil, free of charge. The recall began on July 25, 2014. Chevrolet owners may contact GM at 1-800-222-1020. Buick owners may contact GM at 1-800-521-7300. Note: This is an expansion of recalls 12V-522 and 13V-023.

General Motors is recalling certain model year 2012 Buick Verano, Chevrolet Cruze, and Chevrolet Sonic vehicles. The driver side frontal air bag has a shorting bar which may intermittently contact the air bag terminals.

The windshield wiper washer hose on these vehicles may separate from the washer fluid reservoir. If this occurs, washer fluid will not be available to the windshield.
Risk: A lack of washer fluid could impede the driver's view, increasing the risk of a crash.
Remedy: GM will notify owners, and dealers will secure the windshield washer hose to prevent separation, free of charge. The safety recall began on September 7, 2012. Owners may contact the Chevrolet owner center at 1-866-694-6546.

Risk: A MISSING PAD COULD RESULT IN REDUCED BRAKE SYSTEM PERFORMANCE, INCREASING THE RISK OF A CRASH.

NHTSA defect investigations
Opening an investigation isn't a finding of a defect. Outcomes are as NHTSA's summary states them. A recall is shown as an investigation's outcome only where NHTSA's summary names it; other recalls NHTSA's file lists with it are marked as listed, not caused.
