Ford significantly increased the number of vehicles it’s recalled in 2015 on Wednesday when the car manufacturer announced six new recalls covering nearly 380,000 automobiles — some of which have already been called back, but may continue to have issues. The largest of the recalls includes 342,271 model year 1998 to 2003 Ford Windstar minivans that were originally recalled in 2010 for having a rear axle that could crack over time. Ford said on Wednesday that the previous recall remedy of placing brackets on the axle may not have fixed the problem.
