Leased 2005 Mazda 6 in July 2005. September 2005: took in for service for check engine light. Dealership replaced a purge canister valve. While driving vehicle after repairs were made, I heard a high-pitched whirring noise from the engine and returned the vehicle to the dealership for service. Tech determined noise was coming from transmission. Trans. Was replaced two times; noise did not go away. Tech then determined it was the fuel pump. That was replaced but noise remained. Tech then suspected the fuel lines were vibrating, added a clip to prevent rubbing and noise disappeared. That took 28 days. Day after vehicle left dealership, fuel tank leaked fuel upon starting the vehicle. Dealership determined that a cap had not been tightened. Cap was tightened and car was returned but smelled awful. Dealership shampooed interior. June 2006: while driving, tachometer suddenly bounced and vehicle did not respond to accelerator being pressed. After turning car off and restarting it, car worked fine, but was taken to dealership. Tech replaced throttle body. April 2007: vehicle stalled while waiting at traffic light. Attempts to restart failed. Vehicle was towed to dealership. Tech determined that a fuel pump fuse had become disconnected. Fuse was replaced. One week later, fuel tank leaked upon starting the vehicle. Vehicle was towed to dealership again. Fuel pump assembly had to be replaced. I do not have vehicle back yet.
