2016 Mazda CX-5 other reported problems

UNKNOWN OR OTHER

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.

In 2024 I started having problems with my battery replaced it 3 times last time with a Mazda battery per Mazda advice. The car started to jerk while driving took it back to Mazda said it could be fuel injectors. They cleaned them and problem persists. Took it back they cleaned purve valve and then I broke down while leaving on [XXX] . Called service dept called police since it was in the middle of the blvd. And in traffic. We were lucky no one hit us. They took my car gave me a loaner had it for 10 days. Couldn’t find any problems. Then in 4/2025 it completely died at my home I called Mazda they were able to jump the battery and had it for a month. Couldn’t find any problem. And now we are in 5/2026 my car was in my drive without out being driven for 3 days and now is dead once again. But it is so dead that I cannot open with fob and dash board is black.

The vehicle's air conditioner expansion valve is defective/malfunctioning. While driving the vehicle with the air conditioning operating a loud whooting noise fills the interior of the vehicle. The noise sounds like the siren/hooting sound the police make when they want you to pull over or get out of their way. But the sound is loud and comes from inside the car jarring the driver and passengers. I purchased the car in early 2017 new. I first noticed the AC issue in the summer of 2018. I brought it up to Herzog-meir mazda (where i bought the car) when scheduling an oil change. they said they could not replicate it and so there was nothing they could do. I brought it to them at least 4 times with the same issue. Each time they sent me on my way and said they couldn't replicate it. I brought it up to Foothills Mazda in Spokane in 2023 and again they said that they couldn't replicate it and sent me on my way. This past august i had to schedule the car for an update covered by a class action lawsuit and had them look at the noise issue again. Prior to scheduling I has research online if others have had the issue and low and behold lots of mazda owners have. It is a known issue that mazda has created a "helpline" to deal with it. So I brought it up while scheduling it and asked to make sure they researched the AC expansion valve prior to my appointment (more than a month out). The Mazda lady that scheduled my appointment heard the noise several times with I was idiling the car and finishing scheduling the appointment. The first available appointment wasn't until Oct 1st so of course it wasn't hot enough outside to replicate the situation that causes the noise. Again, they charged my the diagnostic fee and sent me on my way. [XXX] [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My 2016 Mazda CX-5 has had ongoing issues with the infotainment. It freezes up in cold weather and the screen goes blank for long periods of time. This has been an ongoing issue with Mazda vehicles. I had to replace the SD Card in December 2024. The cost was $326.50. There is currently a class action lawsuit by Frederick Law Group 836 Philadelphia Street, Indiana, Pa 15701, Phone number 724-801-8555. When the infotainment goes out during phone calls or navigation, it is a distraction while driving. I called Mazda and chatted with Travius about this issue and forwarded by receipt for the part. He said Mazda would not reimburse me. Can the NHTSA help in getting the reimbursement do you have any suggestions?

My infotainment screen for my Mazda CX5 has bubbles on it. I contacted Mazda and they said this is an issue that many people have complained about, but there is no recall. The screen on the inside has a screen protector that is peeling off and eventually I will not be able to use my touchscreen. There should be a recall or an investigation into this issue. Please help or let me know where I can get more information. I should not have to pay $900 for a new screen kit.

Ghost Touch on infotainment system. The infotainment system will randomly make selections - make calls, change gps location destination, change settings, turn off screen, give verbal instructions, etc while driving. This is very distracting and can be a safety issue.

The 'Infotainment' system in my car stopped functioning which in turn disabled the back-up camera. Mazda knew about this issue, which has been widely acknowledged as a manufacturer's defect in the system, shortly after my purchase of these vehicle. They took responsibility for this issue in the Seattle area when a large number of these units all became defective at once. However, they seemingly went out of their way to not acknowledge this issue to the rest of their customers. They issued a TSB to their dealers (tech service bulletin 09-017/17) to help them resolve the issue with any dealer inventories, but there was no notice to customers nor any recall. The absence of the rear view camera is a safety issue that I believe should have been addressed.

My 2016 Mazda CX5 lost the main computer. This powers the nav system, radio, apps associated with the vehicle but most importantly, the rear view camera. As a result, the back up camera does not work properly due to the computer system remaining in a reboot mode. When I initially reported the problem to Mazda they indicated that they would order the part. They claimed supply chain issues and as a result, kept pushing the replacement delivery date forward. It has been over a year and was just advised there is another 4-5 months wait time. My wife and I have been very patient but recently, events took a turn for the worse. The car must have been designed with the rear view camera as a solution in the reduced visibility of the actual car design. My wife came close to backing into a child. This has scared us now and unfortunately the car can’t be traded in without taking a financial hit. There has been no real answer why this part is taking 1.5 years for delivery but we can’t believe the lack pf attention that Mazda has placed on our concerns. This is absolutely a safety issue and someone needs to investigate if this is happening with many of these vehicles. I would hate to see someone lose their life due to corporate neglectfor safety. Thank you for listening.

I was driving down the highway when my moonroof suddenly and unexpectedly “exploded.” I quickly came to the conclusion that it didn’t happen due to an external cause; I hadn’t gone under an overpass and there weren’t any other vehicles nearby that could have caused an object to hit my car. The weather had been clear that day, and my car had been parked in the shade prior to this happening. When I got to my destination a few minutes later, I could see the glass had broken outward.

As I was driving to work, the moonroof window exploded causing glass to fly every where. Thankfully, I had my sunshade closed so no glass came into the vehicle. Had it been open, I would have been hit by glass shards. There had been no damage to the moonroof window previously, no cracks or issues that I was aware of. While attempting to get it repaired, I was told that this had happened on the same type of vehicle one other time that the shop was aware of. I am currently waiting to hear back from Mazda regarding replacement/repair for the moonroof.

AT 38,000 MILES THE AC WENT OUT, WOULD NOT BLOW COLD AIR. HAD IT INVESTIGATED, AND TH SYSTEMS NEEDED A REFRESH. DYE WAS USED TO DETERMINE WHAT MAY BE LEAKING, NONE FOUND. HOWEVER A YEAR LATER SAME ISSUE- CONFIRMED THROUGH TSBS THAT MAZDA EVAPORATORS HAD POOR BRAZING AND COULD DEVELOP SLOW LEAKS. THAT IS THE CASE WITH THIS CAR, AND NOW THE COMPRESSOR HAS FAILED, LIKELY DUE TO LOW COOLANT LEVELS FROM THE LEAK. MAZDA NOT WILLING TO SUPPORT THIS ISSUE.

AS I WAS DRIVING ALONG THE INTERSTATE, THE GLASS ON MY SUNROOF EXPLODED. THE WEATHER WAS ABOUT 70 DEGREES OUTSIDE AND THE CAR IS TYPICALLY GARAGED EXCEPT FOR WHEN I DRIVE IT. WE DID NOT KNOW AT FIRST WHAT HAD HAPPENED AND IT WAS EXTREMELY FRIGHTENING AS THE SOUND WAS VERY LOUD. THERE WAS NO PREVIOUS DAMAGE TO THE SUNROOF--CRACKS, ETC. AND IT WAS A FACTORY-INSTALLED SUNROOF. AS YOU WILL SEE FROM THE PHOTOS, THE GLASS EXPLODED FROM THE INSIDE OUT.

ON SEVERAL OCCASIONS SINCE PURCHASE SEPTEMBER 15, 2016, THE CAR WILL INTERMITTENTLY UPON APPLYING THE BRAKE TO STOP, ACCELERATE RAPIDLY. IF MY FOOT WASN'T ON THE BRAKE I WOULD BE PROPELLED INTO ONCOMING TRAFFIC OR POSSIBLY INTO A CROSSWALK. I HAVE REPORTED THIS TO THE DEALER WHERE I BOUGHT THE CAR AND TOLD THEY COULD NOT REPRODUCE THIS EVENT AND ALL CHECKS OF THE CAR WERE NORMAL. I AM AFRAID TO DRIVE THE CAR. THE LAST EVENT WAS YESTERDAY, MAY 24, 2020. I HAVE READ OF OTHER OWNERS OF THIS 2016 GRAND TOURING CX-5 MAZDA TO HAVE HAD THE SAME ISSUE WITH NO ACTION ON THE PART OF MAZDA. THIS IS EVEN AFTER ACCIDENTS OCCURRED.

ON MARCH 1, 2020, MY WIFE WAS DRIVING STRAIGHT SOUTH ON RT. 41 (TAMIAMI HIGHWAY) IN NORTH PORT, FLORIDA WHEN ALL OF A SUDDEN SHE HEARD AN 'EXPLOSION' THAT STARTLED HER. IT WAS THE SUNROOF THAT EXPLODED FOR NO APPARENT REASON ON OUR 2016 MAZDA CX-5 PURCHASED IN SEPTEMBER 28, 2015 AND CURRENTLY WITH 62,000+ MILES ON IT. FORTUNATELY, THE UNDERLYING SUNROOF PANEL WAS CLOSED, SO NONE OF THE GLASS FRAGMENTS ENDED UP IN HER FACE/ARMS/CHEST, WHICH, IF HAPPENED, COULD HAVE ALSO CAUSED AN ACCIDENT.

I WAS DRIVING DOWN THE HIGHWAY AT APPROXIMATELY 65 MPH WHEN I HEARD A LOUD EXPLOSION FOLLOWED BY THE SOUND OF BROKEN GLASS. I IMMEDIATELY PULLED OVER AND DISCOVERED THAT THE SUNROOF HAD EXPLODED. THERE WERE NO OTHER VEHICLES NEARBY WHEN THE SUN ROOF EXPLODED AND I DID NOT SEE OR FIND ANY OBJECTS THAT MAY HAVE CAUSED THE GLASS TO BREAK. THE REMAINING PARTS OF THE SUNROOF WERE DIRECTED OUTWARD FROM THE VEHICLE, INDICATING THAT IT HAD EXPLODED OUTWARD. IT WAS A HOT DAY (90+ DEGREES) AND THE AC WAS ON IN THE VEHICLE. AND WHEN THE SUNROOF BROKE THERE WAS A VERY LOUD EXPLOSIVE SOUND. IT IS ALSO INTERESTING TO NOTE THE THE GLASS WAS COMPLETELY SHATTERED INTO SMALL PIECES, MANY OF WHICH FELL INTO THE CABIN.

DURING THE COLD WEATHER, THE CAR STRUGGLED TO START. AFTER STARTING, THE PARKING BRAKE LIGHTS FLASHED ON BOTH THE PARKING BRAKE BUTTON AND IN THE DASH. THE CAR DROVE AS IF THE BRAKE WAS DISENGAGED BUT THE FLASHING LIGHTS CONTINUE (PARKING BRAKE LIGHT FLASHING). A QUICK GOOGLE SEARCH SHOWED SEVERAL OTHERS WITH THIS ISSUE AND A WEBSITE SHOWS THIS ISSUE ALSO HAS OCCURRED IN THE PAST WITH OTHER 2016 MODELS THAT HAVE HAD RECALLS (MAZDA6). SO FAR MAZDA DOESN'T SEEM TO HAVE A RECALL ON THIS ISSUE.

LARGE FISH HOOK SHAPED CRACK ON WINDSHIELD OF MY 2016 MAZDA CX-5 WITH 23000 MLES. THE CRACK APPEARED ON A 55 DEGREE MORNING AFTER I PULLED MY VEHICLE OUT OF THE GARAGE AND DROVE HALF A BLOCK TO A STOP SIGN AND I WATCHED THE CRACK APPEAR. THE CRACK STARTS AT THE TOP CENTER EDGE OF THE WINDSHIELD GOES DOWN ABOUT 6 INCHES, THEN GOES INTO THE VIEW OF THE DRIVER. IT WAS ABOUT 18 INCHES THAT MORNING AND HAS GROWN TO ABOUT 30 INCHES AND A HUGE FISH HOOK SHAPE IN THE VIEW OF THE DRIVER. I WENT TO THE DEALER AND WAS TOLD IT WAS CAUSED BY A STONE IMPACT. IT WAS NOT AN IMPACT, I SHOULD KNOW, I WAS DRIVING. THE DEALER ALSO TOLD ME THAT IT WAS NOT COVERED UNDER WARRANTY, EVEN IF IT IS A DEFECTIVE WINDSHIELD OR INSTALLATION AT THE FACTORY. WITH A LITTLE RESEARCH I AM SEEING A LOT OF CX-5 OWNERS ARE REPORTING SIMILAR ISSUES WITH THE WINDSHIELDS CRACKING FOR NO APPARENT REASON. THIS IS A SAFETY CONCERN THE NHTSA NEEDS TO INVESTIGATE.
