The dominant complaint across these 10 narratives is subframe corrosion. Owners describe extensive rust on front and rear subframes discovered between 88,000 and 90,000 miles, roughly 7–8 years after purchase. The damage is severe enough that multiple mechanics deemed vehicles unsafe to drive. One owner reported steering misalignment, tire screeching, loss of vehicle control, and traction-loss warning lights tied directly to rusted frame damage. Mazda issued a recall (Campaign 19V323000) addressing structure and suspension, and another (2818I) was mentioned, but repairs have proven inadequate—one owner's 2019 recall repair failed, and the subframe subsequently rusted through and broke.
Mazda declined assistance for out-of-warranty owners, citing vehicle age and loss of customer relationship. Subframe replacement parts are on nationwide back order, signaling a widespread issue. Corrosion accelerates in salt-belt states and high-heat climates; owners in South Central Texas, Pennsylvania, Georgia, and Nebraska all reported the problem.
A secondary complaint is dashboard deterioration in hot climates, where the dash becomes sticky and shiny, reflecting light onto the windshield and reducing visibility. Replacement parts have been backordered for months with no recall issued.
One owner also reported a sunglasses holder above the rear view mirror popping out while driving, obstructing rear-view visibility.
Failure modes owners describe

Severe rust and corrosion on front and rear subframes leading to structural failure risk. Multiple owners report extensive corrosion requiring subframe replacement. One owner reports a prior recall repair (2019) that failed, with the subframe rusting through and breaking again.
When: 88,259 to 89,914 miles; reported 7-8 years into ownership; accelerated in salt-belt and high-heat climates
Symptoms owners cite: Tire screeching under normal driving; Steering wheel misalignment while driving straight; Difficult vehicle control; Dynamic stability control and traction loss warning lights; Visible heavy rust and corrosion on frame; Vehicle unsafe to drive per mechanic assessment
Codes mentioned: NHTSA Campaign 19V323000 (Structure, Suspension)
Repairs/costs cited: Subframe replacement required; owners report parts on nationwide back order. One owner's prior recall repair (2019) failed and subframe subsequently broke.
