The Chrysler Group has issued two separate recalls for some of its 2012 models. The first one affects 1,689 Jeep Patriot and Compass crossovers built from December 17, 2011, through January 2, 2012, because of a potential problem with the fuel tank assembly’s roll-over valve. The company said that in these vehicles, the roll-over valve may be damaged and as a result, in the event of an impact or roll-over, gasoline can leak from the tank. The firm’s dealers will replace the fuel-tank on all models free of charge with the recall expected to begin in June. The second recall from the Auburn Hills carmaker involves 289 Chrysler Town & Country and Dodge Grand Caravan minivans from the 2012 model year, manufactured from November 15, 2011, through November 21, 2011. The National Highway Traffic Safety Administration says some of these vehicles may be fitted with right rear hub and bearing assemblies that were not fully machined, something that could potentially lead to wheel separation. Chrysler said that this safety recall will start in April.
