In March of 2016 the automobile company launched safety recall 16V-248 to address unexpected transmission downshifts to 1st gear occurring on certain model year 2011-2012 vehicles. An unexpected downshift to 1st gear can cause the vehicle to slow down suddenly and without warning. This can also cause the rear tires to skid or lock up, increasing the risk of a crash. The automobile company recalled vehicles built between certain production dates to address this defect.
The Office of Defects Investigation (ODI) has received 123 reports concerning the automatic transmission unexpectedly downshifting into a lower gear without input since the launch of 16V-248 on model year 2011-2013 vehicles. Many reports claim the vehicle was not covered under 16V-248 despite having the same symptoms. Additionally, some reports indicate that the remedy was not effective. ODI has received 2 reports of crashes and no injuries.
ODI has opened this investigation to further analyze the scope, frequency and consequence of the alleged incidents.
