NHTSA (USA)High Risk
At a glance
What can fail
Road salt causes corrosive pits on the front suspension coil spring. Over time, the spring can break and puncture a tire if the broken piece contacts it.
What the fix does
Dealers install a guard assembly to prevent a broken coil spring from hitting the tire. Mazda extends lifetime warranty on front coil springs and reimburses prior repairs.
