Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

2014 Mazda MAZDA3 Owner Comments

problem #3

Purchased as new vehicle. From the time of purchase I smelled gasoline in garage after parking overnight. After 1,000 miles/3 months the gas smell became increasingly stronger and gas mileage plummeted from 30 mpg to 18 mpg. Took the car to the dealer for repair. They said the seams of fuel tank were leaking--entire tank had to be replaced; not safe to drive.

Harsh vibration in cabin similar to an engine misfire occurs randomly near idle or immediately after ignition. The dealership and manufacturer have been made aware of this concern and were unsuccessful in reproducing or isolating source of the vibration. Video documentation of the failure during its occurrence has been provided to both parties and has been forwarded to the senior regional engineer for analysis. Current owner has an open vehicle repurchase claim under lemon law with the manufacturer pending investigation of fault.

My car is equipped with a push to start/stop (keyless) "feature". I pulled my car into the garage last night (with the radio off), pressed the start/stop button to stop the engine, and went inside. When I woke up this morning, the car was still running, all night inside my attached enclosed garage. Co meter measure non-zero ppm levels a few hours after shutting the car off. Other then the radio, there are no obvious non-audible indications that the engine is running / not running. Additional expectation would be the car should be smart enough to automatically shut itself off after idling for extended period of time. Mine was running in the garage for about 6.5 hours.
