These vehicles' brake-booster vacuum tube routing can potentially allow oil to access and eventually to degrade the brake booster diaphragm. If this happens, then the vehicles could lose braking assist. The brakes themselves would continue to work, but the driver would experience longer stopping distances. A pop or similar sound of a vacuum leak sometimes precedes the problem, according to the automaker.
Dealers will inspect the components and replace the vacuum tube. If technicians find oil in the tube, they'll also swap out the vacuum pump, brake booster, and master cylinder. Affected owners will receive notice from the company within the next 60 days.
December 3, 2015 , Auburn Hills, Mich. - FCA US LLC is voluntarily recalling an estimated 105,458 compact sedans in the U.S. to inspect and replace vacuum-tube assemblies and certain other components, as required.
Some of the affected vehicles may be subject to oil migration that could affect their brake systems' power-assist feature. Foundation brake function is unaffected. 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.
An FCA US investigation identified certain model-year 2013-14 vehicles equipped with 2.0-liter and 2.4-liter engines, may have brake-booster vacuum-tube routing that inadvertently allows oil to reach the brake booster diaphragm, if ever the vacuum-pump check valve fails. Oil may degrade the diaphragm and lead to a loss of brake-assist – a feature that helps reduce stopping distances.
FCA US is aware of two minor injuries and seven accidents that are or may be related to this condition.
The recall is limited to model-year 2013-14 Dodge Dart sedans produced before Jan. 24, 2014. It 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.
Affected customers will be advised when they may schedule service, which will be performed at no cost.
The condition may be preceded by a pop or a sound consistent with a vacuum leak. Customers who experience such events and/or hard pedal-feel are advised to contact their dealers.
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.
