“I am the original owner of a 2023 Mazda CX-30 AWD (VIN: [XXX]), purchased new on XXX from Mazda of Clearwater, [XXX]. This vehicle has experienced four separate warranty failure events involving critical safety systems within approximately 32 months and 44,530 miles of ownership. In June 2026, at approximately 44,500 miles, my 2023 Mazda CX-30 AWD exhibited sudden RPM lock and inability to shift, with delayed and jerky acceleration. Dashboard warning lights activated including transmission malfunction indicators. DTCs P0756 (Shift Solenoid B Stuck Off) and P0780 (Shift Malfunction) were set. The vehicle was taken to an authorized Mazda dealership. The dealer confirmed the concern and contacted Mazda's regional tech specialist. The valve body was replaced first per Mazda's direction; however, the vehicle continued to exhibit rough and delayed shifting on test drive. Mazda then directed the dealer to replace the full transmission assembly. The repair required 35 days at the dealership. This failure did not occur in isolation. The same vehicle had previously required warranty replacement of brake components (disc, caliper, pads) at approximately 26,400 miles due…”
“Unexpected Automatic Emergency Braking Activation at Highway Speeds in Cold Temperatures. Description: I am reporting a safety issue with a 2023 Mazda CX-30 involving the collision avoidance / automatic emergency braking system. While driving at highway speeds, the system activates a forward collision warning (audible alert and dashboard indicator), followed almost immediately by automatic braking, even when there are no vehicles, obstacles, or pedestrians ahead. Conditions When Issue Occurs: * Ambient temperature: below ~40°F (4°C) * Road conditions: cold, often icy or snowy * Speed: highway speeds 45-75 * Environment: clear roadway, no visible hazards * visibility : clear System Behavior: * Audible warning and visual alert activate * Automatic braking occurs approximately 0.5–1 second after the warning * No obstacle is present to justify intervention Safety Risk: This presents a serious safety hazard because: * Sudden braking at highway speeds creates a high risk of rear-end collision * The warning-to-brake interval is extremely short, leaving little time for driver override. * Occurs in low-traction conditions, increasing risk of loss of control. * The event…”
