While accelerating from a complete stop at a traffic light on a multi-lane roadway, the vehicle suddenly lost all engine power without prior warning. The engine rpm dropped immediately to 0, causing the vehicle to stall in the middle of an active intersection and creating an immediate risk of a side-impact collision from oncoming traffic. All warning lights on the instrument cluster illuminated upon stalling. To clear the intersection safely, the vehicle was placed into neutral and restarted. After shifting back into drive and proceeding out of traffic, the vehicle repeatedly entered a fail-safe/limp mode every 30 to 120 seconds. During these episodes, the automatic transaxle (at) light flashed, the engine shuddered severely, and the engine rpm fluctuated erratically, causing unpredictable acceleration and poor drivability. The sudden stalling in active traffic created a severe hazard to driver and occupant safety. The vehicle had not displayed a check engine light or transmission warning light prior to the complete stalling event.
It's very common in the Mazda 5 cars for the emission components to fail often and affects the fuel economy which causes loss of fuel, money etc. It's also a safety concern as the evap leaks could release fuel vapors to the atmosphere and polluting it. As well as fire hazards due to the fuel leaks. I've noticed many customers approaching the dealer due to this problem which kind of gives us the feeling that this a very common issue with the Mazda5 vehicles.
