2018 MAZDA MAZDA6 Complaints
Have had 3 seats replaced under warranty by Graco and was told to make a report with you. The rigid latch anchors on two have been faulty after 2 months. The second one got stuck in the installed base and pulling the release button did nothing. The rigid latch on the first got stuck in the open position. The second they would move independently of each other and not lock in. The third is starting to have the same issue with getting stuck in the base. These have all happened within two months of normal use.;

2019 MAZDA CX-5 Complaints
1.January 2025 Diagnosis (Inside Powertrain Warranty): I presented the vehicle with severe transmission jerking and shift lurching. Your technicians applied a software flash to the PCM/TCM per TSB 05-004/23. Mazda’s official text states the root cause of this symptom is torque fluctuation and torsional resonance within the torque converter. 2.Current Symptom (Defect Manifestation): The vehicle now exhibits the distinct upshift chirp detailed in TSB 05-005/23 (NHTSA ID MC-10246127-0001). Mazda’s documentation states the root cause of this chirp is excessive wear of the lock-up clutch inside the torque converter, which sheds iron powder directly into the automatic transmission fluid (ATF). The torque converter is a single, closed mechanical component. In January 2025, while the vehicle was fully covered under the 5-Year/60,000-Mile Powertrain Warranty, the torque converter's internal clutch was already undergoing accelerated physical degradation. Instead of physically inspecting the transmission fluid for iron contamination as dictated by sound mechanical diagnostics, your service department applied an electronic software patch. This patch merely altered the lock-up engagement timing to mask the torsional resonance rather than fixing the failing hardware. Applying a temporary software patch that delays a catastrophic component failure past a calendar date does not absolve Mazda dealership or Mazda Corporate of liability for a pre-existing, documented defect. In addition there is numerous complaints related to same issue is being poped up online and it appears to be wide spread manufacturing defect problem.;
