“The contact owns a 2015 Mazda CX-5. The contact stated that while pressing the brake pedal the engine had experienced very high revving and the vehicle would lurch forward. The vehicle was taken to the local dealer who performed a PCM and TCM program update and reset the KAM per the manufacturers TSB. The contact indicated that the failure was corrected for a while but recently the failure had reoccurred. The local dealer was contacted and a service appointment was scheduled. No further information was available. The manufacturer was not yet notified of the failures. The failure mileage was 25,000.”

“I was near a red light and applied the brakes, but the car accelerated and ran into the truck stopped in front of me. This happened around May of 2024. I took the car to the Elk Grove Mazda dealer. They ran diagnostic and road tests but found nothing wrong. The car had the same problem again sometime later inside my garage. The car rammed into the drywall while I tried to stop by pressing the brake pedal. I took the car to the AAA repair shop in August 2024. They spent three days, and they told me they found a problem with the "steering angle sensor." It was 22 degrees off calibration. They reset the sensor, and the car ran better. However, the car acted again after some driving. It tries to accelerate while I apply the brake pedal near a stop. I took the car back to the AAA shop, but they did not find any problems in a whole week. I still drive this(my only) car, but extra careful, keeping a longer distance between cars in front of me and braking ahead few times ahead of any stop.”

“While driving on the freeway the check engine light came on. I was able to drive the car home the remaining 20 minutes but there was some noticeable difficulty accelerating. When I went to turn on the car later that day the engine would not turn over and there was an audible rattling/chugging sound and the car itself shook. I was unable to get the car to start and the check engine light remained on. I had AAA check the battery the next day and confirm it was not a battery issue and a diagnostic revealed the P0192 code. AAA towed it to their shop where it was confirmed by the manager mechanic that the issue was with the high pressure fuel pump and that it was causing an issue with the low pressure fuel sensor as well. The mechanic was unable to determine what caused the pump to fail and has quoted me nearly $2000 to fix it. After some searching online it has become clear that this is an issue many other Mazda owners have faced and that is even a recall for the pump for years and makes from Mazda due to a known issue with DENSO fuel pumps causing this exact issue. Despite this being known and DENSO having admitted issue with fuel pumps in cars dating back to…”

“2015 Mazda CX-5 with 91,000 miles on it. Automatic transmission has failed. When I attempted to pull out into traffic the vehicle would not shift into 2nd gear and instead jerked hard and the engine RPMs revved up. I was not able to get the vehicle past 10mph. This failure with the transmission resulted in the oncoming traffic having to swerve and break to avoid a collision with me. The vehicle was taken to a Mazda dealership who did a diagnostic on it and found that the Mazda had an "internal transmission failure" and would require a full replacement. I asked if it would be replaced with the same exact transmission and was told "no, the defect was discovered by Mazda and has been correct for new transmission models." The manufacture knows about this issue. Luckily I escaped serious bodily injury. The problem has been confirmed by the dealer as well as an independent 3rd party transmission repair specialist. There were no warning lamps, messages or other symptoms prior to this incident to give warning.”

“I WAS DRIVING ON THE FREEWAY WHEN I HEARD A LOUD SOUND ABOVE ME, FOLLOWED BY SUDDENLY FEELING WIND COMING INTO THE VEHICLE AS WELL AS HEARING GLASS ROLL OFF THE TOP OF THE CAR. WHEN I WAS ABLE TO SAFELY PULL OVER I SAW THAT THERE WAS A HUGE HOLE IN THE SUNROOF BUT NO OTHER DAMAGE. THERE WERE NO DENTS OR SCRATCHES ANYWHERE ON THE TOP OF THE CAR WHERE I HEARD THE SOUND COME FROM. THE REMAINING GLASS WAS ANGLED UPWARDS AS IF THE GLASS HAD EXPLODED. LUCKILY I HAD THE SLIDER UNDER THE GLASS CLOSED SO NO GLASS MADE IT INSIDE THE VEHICLE AS I WAS DRIVING. HAD IT NOT BEEN CLOSED IT COULD HAVE POTENTIALLY INJURED MYSELF OR MY TWO CHILDREN OR POTENTIALLY CAUSED A COLLISION.”
