2016 Mazda CX-5 Complaints

ELECTRICAL SYSTEM,UNKNOWN OR OTHER — Filed 06/18/2026

Repeated Failure and Rebooting of Mazda Connect Infotainment System I am the owner of a 2016 Mazda CX-5. The factory Mazda Connect infotainment system has developed a recurring defect in which the system repeatedly reboots to the Mazda logo while driving. Prior to complete failure, the navigation system became intermittent and Bluetooth connectivity frequently disconnected, requiring repeated attempts to reconnect devices. The system now continuously cycles through the startup screen, making navigation, hands-free phone functions, and system settings inaccessible. These repeated reboots occur while the vehicle is in motion and are distracting to the driver. The flashing and rebooting screen repeatedly draws the driver's attention away from the road and interferes with the use of navigation and hands-free communication features that are intended to promote safe driving. After researching this issue, I found numerous reports from other Mazda owners experiencing the same symptoms involving the Mazda Connect system, navigation SD card, and Connectivity Master Unit (CMU). The frequency and similarity of these reports suggest that this is a widespread and well-known defect rather than an isolated incident. Because this defect affects driver attention and the safe operation of the vehicle's communication and navigation functions, I respectfully request that Mazda and the National Highway Traffic Safety Administration investigate this matter and require Mazda to issue a recall or establish a repair program for affected vehicles.

VISIBILITY/WIPER — Filed 05/25/2026

(I am the owner of the car and am filling this out for my daughter who was driving it at the time, I was not with her during the incident) While driving down the road in the rain the wipers just stopped working. I have not had any dealers ID the specific problem yet. We replaced the wiper 20amp fuse and it did not fix the problem. There were no warning lamps and there are still no warning lamps. My safety was put into danger when I could not see out the window. I was nearly at work so I waited for the rain to slow down some was able to make it to work. The rain cleared while I was at work and it has not rained since. It is available for inspection upon request.

POWER TRAIN — Filed 04/27/2026

Any time the vehicle has been sitting with the engine off and has been given enough time to “cool down”, upon starting the vehicle and switching from PARK to DRIVE, the vehicle will violently lurch forward while attempting to reach 2nd gear. This is dangerous behavior that is not normal for any vehicle. There is clearly something wrong with either the transmission or the way the software communicates with the transmission. When the engine is within normal temperature it doesn’t display this dangerous behavior. A similar TSB was issued for the 2nd generation of CX5s but not for this generation of CX5s

STEERING,SUSPENSION — Filed 05/07/2026

VEHICLE SPEED CONTROL,ENGINE,FUEL/PROPULSION SYSTEM — Filed 04/19/2026

My wife was driving our 2016 Mazda CX-5, and was getting ready to pull into our daughters' driveway. My wife slowed down to a stop before entering the driveway. She gave the vehicle some gas to move forward. She stated that there was a pause, then the vehicle accelerated forward slamming into the garage door and the corner of the garage/house. There was also a Tesla parked inside the garage that was knocked back about a foot and a half. The distance from the edge of driveway and street to the garage door is about 27 feet. This happened at 1:30 PM. The weather conditions were great, sunny and dry. Thankfully, no one was hurt. If my wife was another foot to the right, she would have hit the support post for the upper balcony, and there would have been a good chance of the balcony falling on top of her. Or, if someone was standing in front of my wife when she entered the driveway, they could have seriously been hurt! There were no warning lights on prior to the accident. This happened last Sunday, April 19, 2026. We had the car towed to a local body shop on the same day as the accident. The vehicle was towed away the very next day to our insurance company's salvage lot in Bakersfield. I do have all the information, address and phone number, of the lot where our car was towed to. Hopefully, the car can still be inspected by the proper authorities. Thank you for your time!
