Saltwater intrusion is being blamed for Mazda's latest recall, to replace front suspension control arms that could fail on the CX-7 crossover.
Mazda and Transport Canada say corrosion of the front control arm (this is the piece that attaches the front wheel to the car's structure, while allowing it to move up and down with the suspension) could cause the ball joint (that's the bit that lets the wheel turn with the steering) could separate and very likely lead to a loss of control.
We find Transport Canada's use of the term "saltwater" a little weird; we figure they're talking about corrosion caused by the road salt many Canadian cities dump on roadways during the winter months, which is the culprit behind numerous corrosion recalls related to vehicle suspension components, like this, and this.
This recall affects nearly 29,000 examples of the CX-7, a compact crossover sold between 2007 and 2012 and which was replaced for 2013 by the CX-5.
