Fiat Chrysler issued a recall for 105,458 Dodge Dart models in the US and another 16,145 units worldwide for possible problems over power brake assistance.
Fiat Chrysler is voluntarily recalling an estimated 105,458 Dodge Dart compact sedans in the US 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. The automaker says the 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 investigation from the company identified that certain model-year 2013-14 vehicles equipped with 2.0-litre and 2.4-litre 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, which could potentially turn into longer stopping distances.
Fiat Chrysler US said it was aware of two minor injuries and seven accidents that were or might be related to this problem. The recall is limited to model-year 2013-14 Dodge Dart sedans produced before January 24, 2014. It also affects an estimated 11,996 cars in Canada, 3,705 in Mexico and 444 outside the NAFTA region, while models equipped with the 1.4-litre engines are not targeted by the recall. The issue may be preceded by a pop or a sound consistent with a vacuum leak and 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.
