The defect
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.
The 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.
The 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.
