The contact owns a 2022 Mazda CX-5. The contact stated that while driving from a stationary position, the vehicle failed to properly accelerate while depressing the accelerator pedal. The contact indicated that the vehicle would not immediately respond and would drive very slowly before accelerating. Additionally, while driving around corners the steering wheel was very difficult to maneuver, making the vehicle difficult to control. The vehicle was taken to the local dealer who was unable to identify a cause for the failure of the vehicle. The failure mileage was 100.

Unexpected acceleration ___ While stopped on a slight downgrade, RPM suddenly increased and vehicle lurched forward. Applying more pressure to brake stopped movement. I forced transmission into park. Took foot off brake, RPM still high. Tapped accelerator, RPM dropped to normal idle. Fortunately, there were no vehicles in front of mine and cross traffic was not present. Vehicle did not enter intersection. I drive single footed and shoe did not overlap brake and accelerator. The day was clear 37F, dry. Vehicle had made 3 short trips prior so engine was up to temperature, 35 miles total over 2 hours. Cruise control was not engaged and had not been used in two days. This issue has not been reported to dealer. There were no warning lights or other indications of problems. The vehicle has driven normally since. I have not been able to reproduce the issue. ____ A similar issue happened two months prior. Circumstances were not the same. Intersection was flat, engine was not up to temperature, removing pressure from brake pedal was enough to stop high RPM. Attributed instance to the shoes I was wearing. The running shoes were thicker and wider than I normally wear while driving. I believed I may have pressed both brake and accelerator without realizing it since reducing pressure corrected the problem.

When coming to a stop, car accelerated and went over curb. From a search of the internet I found examples with this and other cars where people with larger shoes had the same problem of pressing the brake and unintentionally pressing the accelerator pedal at the same time. I read of one manufacturer that programed the car to brake if both pedals are pressed at the same time and ignore the accelerator. The same thing happened in my 2015 Mazda CX5. In that case I had it checked at the dealer. The technician found nothing wrong but was able to reproduce the problem when his boot pressed both the brake pedal and accelerator because both pedals were so close together. Since this would probably be an inexpensive software change, it would be prudent for a safety recall by manufacturers that have pedals that are close to one another.

I have had a system malfunction, that has caused a dead battery in May 2022 and then again Aug 2022. The car was in park and I received a notification on the Mazda app about 5 hours after being in the car that stated "Critical Vehicle Malfunction Alert." I had to have my car towed and serviced at a Mazda dealer but they found no issue with the battery. This happened again in August. According to the Mazda C-X5 Manual, like all modern cars, even if something was left on (light on, door open, ACC on) it should automatically turn off after 25 minutes.

On July 22, my sister and I were traveling on I-95 going south. We stopped at the Maryland House near Aberdeen, MD. I was looking for a parking place and was driving very slowly. I slowed further to turn into a place on the right, near the south end of the parking lot and was attempting to put the car in park when the car accelerated abruptly, lurched forward, crossed over the concrete curb at the end of the parking space, and was heading right for I-95 which was straight ahead. I had never taken my foot off the brake. I tried to brake harder but that did not stop the car. I therefore turned right onto a service road to avoid crashing onto I-95. I then noticed a car coming toward me and swerved to the right back toward the parking lot, crossing over the curb at that parking spot, and slamming into a parked car and side swiping a truck. I only took my foot off the brake when the car stopped. The airbags did not deploy. After the car stopped, I was unable to turn the engine off. When I returned home, I looked on line to see if anyone else had reported a similar experience. Apparently there have been a number of similar occurrences with Mazda CX-5s (see https://www.carproblemzoo.com/mazda/cx-5/car-accelerates-on-its-own-problems.php) including a description of almost the same event with a car that also had low mileage. In several of the cases listed, the airbags likewise did not deploy. Note also that the police report may not include the origin of the incident but only the crash into the other car. I was in shock and was not able to give full information. I have asked for the complete information to be added to the report. Also of note, and possibly related: Earlier in July, an alert ‘brake, brake, brake’ sounded and there was a flashing on the dashboard that said ’’brake’. I took the car to Mazda, who could not find a problem and told me to return if it happened again.
