What 2020 Mazda CX-5 owners say
Most recent owner complaints, unedited.
While driving on the highway in traffic, I was applying the brakes (slowly and smoothly) and moving with the flow of traffic when the SBS system activated the brakes harshly and slammed me to a stop without reason. In addition to throwing me forward against my seatbelt, it also resulted in the car behind me rear-ending me. I did not hit the car ahead of me, since I was far enough behind them BEFORE the smart brake support engaged, but the feature caused an accident that could have been avoided.
While driving my vehicle the systems sensors are affected by nearby drivers which cause the car to stall in the middle of traffic going between 40 and 75 miles per hour.
The vehicle reboots the screen/infotainment system while driving. The dealership has updated the software and replaced the screen (Screen was at my cost). They reset the codes and it comes back. This is a safety hazard as it could cause non compliance with the FMVSS in regards to rear-view cameras being required. There is currently a settlement in place under a class action.

My car has started braking when objects arnt there almost causing a crash Mazda denies this
During snowfall, the front camera becomes obstructed, leading to a malfunction in the smart brake system. When this occurs, an alert appears indicating a “Smart Brake Failure,” accompanied by an audible warning and the illumination of the check engine light. The vehicle then exhibits unpredictable behavior, including unintended braking and sudden acceleration, creating a hazardous driving situation. The only temporary resolution is to restart the vehicle; however, the check engine light remains on for several days before eventually turning off. This issue occurred while I was driving on the highway on February 19, 2025, posing a significant safety risk. This is not the first time the car has done this.
Forward Braking Safety Sensor Was on transmission after braking check engine light . Was driving car from work it lost all power . And those warning â ï¸ light indicators where on . Car wouldn't go over 15mph . Took vehicle to mazda and dropped it off as my husband requested information do so . Mazda called say diagnostic saying it needed plugs ,coil packs serpentine belt and adjuster pulleys replacement. I called my husband he's a mechanical engineer he said no way it needs a tune up that early. He requested information go get the car as he flew home from working outta town. We took it to scooter's place certified mechanic in Indian Head md . Scooter's place diagnostic scan said completely the opposite. Say it was the cars brain aka cpu send false signals causing misfire to all components of vehicle . He change one spark plug and car ran normal. He told us it wasn't a fix it was cpu and no matter tune up or not . The computer was the issue. I went back to passport mazda in Suitland Maryland to give them second opinion issues the GM wouldn't give my money back for false diagnostic readings and refused to listen or hear what I had to say I was to upset to continue and decided to leave . He kept saying he wasn't a technician so he doesn't know but was explaining technician issues that were incorrect i have both diagnostic detail paperwork which i will attach with report
"ghost touch" issue on my cars touch screen operates by itself or doesn't respond. I was driving down a dark road when it went black, the screen had adjusted its brightness down to zero! The radio will change stations then freeze and the manual controls won't even work.
Display went dark and did not display. This is not the only time it happens. It acts like someone’s touching the screen even when in motion. It prevents the reverse camera from displaying.
