5/5 Overall
NHTSA 5-Star Safety Rating
The dominant pattern in 2012 Chevrolet Sonic complaints centers on the powertrain, which accounts for the largest share of reports by a wide margin. Owners frequently describe transmission problems, the most common being the vehicle refusing to shift out of first or second gear, getting stuck in a single gear while driving, and failing to engage properly from a stop. Some owners report needing multiple attempts before the transmission responds at all. The engine category draws a separate cluster of complaints involving sudden power loss while driving, sometimes accompanied by the check engine light and loss of communication between the diagnostic system and the transmission. Electrical system complaints, while lower in volume, include warning lights for brakes, ABS, and traction control illuminating together, occasionally paired with reports of reduced braking response.

By System
The 2012 Chevrolet Sonic has 4 recalls, the most serious being a missing front brake pad on certain vehicles that reduces braking performance and raises the risk of a crash.
On the drivetrain side, vehicles with the 6-speed automatic transmission and 1.8L four-cylinder engine may have a transmission turbine shaft that fractures, preventing the transmission from shifting past second gear and limiting the vehicle's top speed. There is also an electrical concern involving a Calix-branded device: the cord's wiring can become exposed, creating a risk of electric shock if someone handles the cord while it is plugged in. The remaining recall covers the windshield washer system, where the washer fluid hose can separate from the reservoir, cutting off fluid to the windshield and reducing visibility while driving.
