AUBURN HILLS, Michigan — Fiat-Chrysler is recalling an estimated 105,458 2013-'14 Dodge Dart compact sedans in the U.S. to fix a potential problem with the brake systems' power-assist feature, the automaker said on Thursday.
Certain Darts 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," Fiat-Chrysler said in a statement.
Two minor injuries and seven accidents have been linked to the recall.
"Foundation brake function is unaffected," Fiat-Chrysler said. "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."
The recall is limited to Darts produced before January 24, 2014. Vehicles equipped with 1.4-liter engines are not affected.
Dodge dealers will inspect and replace the vacuum tube. If oil is found in the vacuum tube, dealers will also replace the vacuum pump, brake booster and master cylinder. A date has not been set for the recall. Owners can contact Fiat-Chrysler customer service at 1-800-853-1403.
No information about the recall has been posted on the website of the National Highway Traffic Safety Administration, which oversees vehicle safety in the U.S.
Edmunds says: Fiat-Chrysler tells owners of these cars that the problem may be preceded by a "pop or a sound consistent with a vacuum leak." Customers who notice that or experience a hard pedal feel are advised to contact their dealers immediately.
