2014 Mazda MAZDA6 West Allis, WI

FUEL/PROPULSION SYSTEM

My 2014 mazda 6 EVAP system pops the p0451 when filling up gas to the first click. It goes away after a while if I take care to not fill up the tank all the way to the top. It is similar to a issue reported by recall 7414D for other 2014 mazda 6s. My car is not covered by the open recall, but it is experiencing similar issues. The p0451 goes on and off depending on how much i fill up the gastank.

2016 Mazda MAZDA6 Wappingers Falls, NY

FUEL/PROPULSION SYSTEM

Fuel smell in & outside of vehicle after fuel fill, being a retired Master Technician I decided to investigate this and after removing the the fuel tank access door under the rear seat I was shocked to see that on an 8 year old vehicle the fuel sender retainer is completely rusted out. An overfill, an aggressive maneuver or small collision could prove disastrous with this condition pending! I have just ordered a replacement since I intend to repair this myself and that is only of the tank itself is not compromised when I proceed to remove the rusted out screws as well. Also after further investigation I find this is nothing new to Mazda and actually had this same condition in previous years but I assume chose not to prevent it from happening in future models. I will be attaching a photo of it.

2017 Mazda MAZDA6 Waco, TX

FUEL/PROPULSION SYSTEM

2017 Mazda6 Infotainment System also found in Mazda CX-5. Known as "Ghost Touch," it is a known issue acknowledged by the company and dealerships. Available for inspection upon request. The Infotainment system controls navigation, ADAS heads up navigation, illumination of instruments and other driver instrumentation and safety warning systems. Above a set speed the screen is NOT a touch screen. When the car slows below a preset speed or is stopped, the display screen becomes a touch screen. The screen will then randomly and intermittently begin to reset itself, changing between and altering settings. This was repaired by Mazda on pre-2016 models, but Mazda declined on 2017-2020 models. This has the potential of causing accidents by making instrumentation unreadable, random dialing bluetooth phone connections, etc. As stated search for "Ghost touch Mazda" and you will find many references and complaints. The problem is ongoing since 2021. The component has apparently been upgraded but will cost 700+ to repair.

2009 Mazda MAZDA6 Racine, WI

FUEL/PROPULSION SYSTEM

Unknown Upon research I saw there was a prior recall Mazda Recall Number 6211B NHTSA Campaign Number 11V134000 About January of 2022 My service engine light has been turning on and off Around and about July 2022 I noticed a dark black colored puddle gathered wherever I would have my vehicle parked and there is a gas smell upon entering the vehicle. I took my vehicle to a mechanic and after their initial inspection I was informed that they would have to further inspect my vehicle but it would be costly because they would have to remove exhaust system to have a better visual. Mechanic also advised not to fill up my gas tank when refueling I believe my vehicle has the problem that the said recall describes
