MAZDA Complaints

Coolant was leaking into my engine where the oil goes and I was unaware. The vehicle stalled in me while driving because of this. Even after figuring out what the issue was and trying to have it fix it became inoperable.

After topping off my fuel tank at a gas station, fuel begins to leak from the top of the tank. Prior to noticing the leak, I had noticed a strong smell of gas after topping off and driving home. Symptoms include smell of gasoline, and a gasoline puddle on the ground. The fuel appears to be leaking from the top of the fuel tank, running down the side, and dripping onto the ground. Because of other nearby components that generate heat, this is a very dangerous situation that may lead to fires. Other 2012 Mazda 3 owners have experienced the same exact situation. The following threads shows comments from various people that have experienced the issue. The component that seems to have failed is the vent hose which allows gasoline to seep to the exterior of the tank. Fuel leaks are extremely dangerous as sparks, matches, cigarettes, or other heat sources can ignite the fuel leading to a total loss. https://www.mazda3revolution.com/threads/fuel-leaking-from-gas-tank-area-after-filling-up.236569/ https://www.mazdaspeeds.org/index.php?threads/resolved-fuel-leak-by-tank.14228/ Quotes for repair seem to vary with some people claiming up to $900.

UKNOWN-Seat Heating system in my car gets too hot to the skin where it burns the skin if not turned off. I’m not able to use it often because even on low setting it gets extremely hot.

Automatic emergency braking suddenly engaged while driving on the highway. The car decelerated abruptly to a complete stop, causing the driver behind to rear-end me. There were no vehicles or obstacles in front of the car when the brakes engaged - the closest car was at least 100 feet in front of me. This collision was clearly the result of a faulty automatic emergency braking system. I do not feel safe driving the car knowing this malfunction could happen again, especially at highway speeds. Sudden unexplained braking presents a huge safety hazard to all drivers, increasing the likelihood for collisions and injuries. There were no warnings or symptoms prior to the unexpected brake system activation. After the brakes activated mistakenly, warning beeps and “BRAKE!” message appeared. Car has collision damage and has not yet been inspected by dealer. Police report filed.

I was traveling behind a propane truck, that was going to make a right turn. I disengaged the adaptive cruise control by tapping on the break. I began coasting to a stop, suddenly the car began accelerating again with no warning. I was forced to make the turn with the propane truck and side swiped the truck in the process.

Engine cylinder head cracks open due to bad design where turbo puts too much weight and vibration resukting in coolant leaking out of engine. Mazda has a bulletin out for this issue and I took it to a Mazda dealer for repair. They confirmed this was the issue.

What component or system failed or malfunctioned, and is it available for inspection upon request? Sudden loss of power (and speed) on interstate highway at ~65 mph. Fuel level was under 1/4 tank level. Weather was clear and approx. 60-70 deg F. Cruise control was on and vehicle working normally for hours on the road trip with cruise control on and functioning properly on the highway. Suddenly, the vehicle lost power, check engine light came on, and vehicle was running very sporadic. P0192 code thrown. Low fuel pressure which resulted in car suddenly going into reduced power mode. Sudden loss of high pressure pump would have resulted in complete loss of propulsion, which did not occur in this case - this indicates low pressure from the in-tank LP fuel pump. How was your safety or the safety of others put at risk? Sudden and unexpected loss of power on the highway which could have resulted in rear end accident or loss of control while trying to get the vehicle off the highway. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes - if fuel tank level gets below 1/4 tank the problem will occur. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No - sudden loss of power and then engine light came on (constant, not flashing) and vehicle had sporadic power issues until we could get off the highway. Certified technician put scanner on car. Code was P0192 - low fuel rail pressure. Filled fuel tank to full, cleared code, and continued to drive car. Issue did not reoccur until fuel level fell below 1/4 level (approx.). 2017 Mazda CX5 is believed to have the same or similar low pressure fuel pump in tank, OEM = Denso, which is on recalled Mazda models from 2018 and newer. I believe older models of Mazda's with the same pumps should also be recalled!

Takata recall. The contact's wife owns a 2007 Mazda Mazda6. The vehicle owner received notification of NHTSA Campaign Number: 17V474000 (Air Bags) however, the part to do the recall repair was unavailable. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue. The contact had not experienced a failure. Parts distribution disconnect.

Engine leaking coolant due to a cracked cylinder head. 55,000 miles on car. No indications of a problem other than odor. Problem was confirmed by an independent service center and dealer. Dealer says engine needs replaced.

I was on vacation and returning home when I got a message on my Mazada App that there was an issue detected. It was time for an oil change which I intended doing when I returned home. The message stated that I had Low oil level and to add 1 qt. of engine oil. The "oil" light illuminated on the dashboard and I immediately pulled over and turned the vehicle off for 5 minutes as stated in the owners manual. When I restarted the car the "oil" light was off but I was very fearful of driving the car as I had 6 hours of driving left to get home. I found an instant oil change facility and immediately had the oil changed and refilled to full. I contacted the dealer to record this incident. The car has 25,000 miles on it and I religiously take the vehicle to the Mazada garage for all required services. This is the first time this happened with this vehicle. My advice from the dealer was to keep checking the oil level every week.
