“When driving at 35-50 MPH, my 2016 Mazda CX-9 periodically brakes suddenly while driving to a scrubbing forceful stop tossing things off the back seat, placing me in danger of a rear-end collision. Sometimes a very quick beeping sound is made, b-r-a-k-e appears on the panel in large letters --- then the car automatically comes to a sudden stop or it occurs with no notice. I have taken it to the dealer 3 or 4 times only to be told that they could find nothing wrong. …”
NHTSA complaint #11091416, filed 2018-05, 16,000 miles“I just purchased my vehicle about 3 months ago. I was running errands about a week after purchase and was heading home on the highway when the gas notification came on displaying 27 miles left and advised me to get gas. I was about half mile from the exit and the vehicle check engine light came on and it started stalling. Thank fully I was able to get over to the median just in time when it shut down completely.

NHTSA complaint #11233883, filed 2019-07, 60,000 miles“The push button on/off switch does not protect against turning the vehicle off if transmission is accidentally left in any position other than 'p'. For example its possible to put the transmission in 'r' and turn the vehicle off. For a busy parent (target demographic of this vehicle), this is very dangerous. If on an incline, the vehicle will start rolling forward or backward (depending on incline/slope and r/d transmission position). …”
