FCA US is recalling an estimated 105,458 2013-2014 model-year Dodge Darts in the U.S. to address a potential brake-assist problem.
Dealers will inspect and replace vacuum-tube assemblies and some other components, as needed, in Dodge Darts equipped with either a 2.0-liter or 2.4-liter engine, the automaker said. The vehicles are at risk for oil migration that could affect the brake systems’ power-assist feature.
“Foundation brake function is unaffected,” FCA US explained in a released statement. “However, if this condition occurs, the driver may notice hard pedal-feel on brake application, and longer distances may be required to stop the vehicle in emergency situations.”
FCA US said it’s aware of two minor injuries and seven accidents that could possibly be related to this condition.
An FCA US investigation found that these cars might have brake-booster vacuum-tube routing that permits oil to reach the brake booster diaphragm, if the vacuum-pump check valve ever fails. As a result, oil may degrade the diaphragm and lead to a loss of brake-assist – a feature that helps reduce stopping distances.
Drivers might notice warning signs of the problem developing.
“The condition may be preceded by a pop or a sound consistent with a vacuum leak,” FCA US said. “Customers who experience such events and/or hard pedal-feel are advised to contact their dealers.”
The recall is limited to Dodge Dart compact sedans produced before Jan. 24, 2014. Beyond the U.S., the recall also affects an estimated 11,996 cars in Canada, 3,705 in Mexico and 444 outside the NAFTA region.
Vehicles equipped with 1.4-liter engines are excluded.
FCA US will advise vehicle owners of when they may schedule service. There will be no charge for the recall remedy. Service comprises an inspection and vacuum-tube replacement. If oil is found in the vacuum tube, dealers will also replace the vacuum pump, bake booster and master cylinder.
