While driving down the road my Mazda CX-5 continues to just stall and the engine light turns on and the safety features turn off. I was driving down a road in town and the engine started stalling as I came to a red light and slowed the engine shut off and I was almost hit from behind. It took several attempts at starting before the car would start. This has now happened for the past 3 days and is happening more and more frequently. I do not have any other means of transportation and after attempting to get the dealership to check due to the recalls on the Mazda CX-5 for fuel pump failure and the mechanic saying it appears the fuel pump is bad the dealership refuses to attempt any repair because the VIN is not listed in the recall at this time. This is a severe safety problem because if it stalls in traffic I will be in an accident as I have no ability to maneuver the vehicle when it stalls to get out of the way of vehicles approaching. If this issue isn't resolved it is going to cause injury to myself or others. People have had to swerve into the path of other vehicles to keep from hitting me when it stalls, which is eventually going to result in harm to others and/or myself and family.

Unknown. The engine started to stall as I was driving and the gas pedal wasn't working. The car shutdown after reaching 0 moles per hour and it would jerk when I tried starting it. The car had enough fuel, battery and was service a month prior. The car would not start and had to wait a few hours to try again. The issue is similar to the recall this model has but when I checked my VIN is all cleared. Please Help.

Mazda recall 5321K NHTSA recall 21V875 has been open since Nov 2021 and notification by letter not received until Jan 2022 stating that a fix may be available by summer 2022. Meaning I am driving a vehicle that may stall at any time possibly causing a crash. This is unacceptable from a safety standpoint. NHTSA needs to apply pressure on Mazda to resolve this ASAP or provide loaner vehicles to those customers at risk.

I was driving on the highway, at about 65 mph. The engine lost power and the car began to slow down. It did not respond to the accelerator, but the power was still on. I was lucky enough to be able to pull over to the shoulder without colliding, but it was extremely fortunate that no cars were obstructing me at the time. I put the car into park once stopped and turned the engine off. I tried to restart but the engine did not turn over and several warning signs came up on the dash and the car emitted irregular dinging/beeping noises before going silent (I do not recall specifically, but I believe the check engine and/or battery indicator lights came on) The hazards worked, also the interior lights. But I was stranded in a remote area in complete darkness on a very narrow shoulder with large trucks whizzing by. A CHP officer appeared eventually and expedited a tow truck, which brought me to the nearest Mazda dealership 100 miles away. It was midnight by the time we arrived. Both the tow truck driver and the technician (the next morning) were both unable to jumpstart the car. Engine would not turn over at all. The technician opened up the engine and sent reports to Mazda. We are waiting to hear back but they would not give me a loaner vehicle without knowing the cause of the failure. Very relieved I was not hurt but also very upset at the chance I could have been.

Vehicle having significant drop in power output in 1st and 2nd gear when ambient temperatures below freezing. Issue resolves when finally shifting to 3rd gear, but lack of predictable response when merging is unsettling.

The fuel low level light is not triggered until 12 miles or less of fuel remaining. The service bulletin provided by the dealership, med center Mazda in pelham Alabama, shows that when the fuel gauge sender voltage from the rbcm and the fuel injection amount from the PCM both agree that 2,6 gallons remain the instrument cluster powers a transistor and turns the light on. In a discussion with the service advisor, we were trying to figure out if there are 2.6 gallons remaining then why the miles to empty does not register 30-50 based on the epa ratings for the vehicle. We decided to disconnect the battery to clear any residual information in the computer and reset the average fuel economy system. While driving the Mazda Cx-5 less than 24 hours after getting it back from the dealer service department, the fuel low level light did not illuminate until 6 (six) miles to empty. I exited the interstate and drove the vehicle about 5 miles to my home. The miles to empty read 0 (zero) when pulling in my driveway. I parked the Mazda and changed vehicles to complete my tasks for the day. Upon starting the Mazda the next morning, the miles to empty still showed 0 (zero) while also showing an average fuel economy at 24+ mpg. I then drove to the gas station where 13.573 gallons were required to fill the tank. That leaves approximately 1/10th of a gallon until the car ran out of fuel, although I had only traveled 6-7 miles after the light came on. Bottom line: There was definitely less than 2.6 gallons in the tank when the fuel low light illuminated which could have caused the vehicle to quit in the middle of the interstate and which could also be damaging the fuel system. The computers, programming, and/or sensors are malfunctioning. The malfunctioning fuel system on the 2019 Mazda Cx-5 could potentially lead to an accident.
