2017 Mazda CX-5

I was driving on the freeway, going about 65 mph at 7:30 am. I heard a loud BANG sound and my sunroof glass exploded into pieces. I had the inside cover closed so the glass did not get in the car. The sound was frightening, loud and caused me to pull to the side of the highway. The vehicle has been inspected by insurance representatives and I had used the sunroof the day before - it worked fine.

The navigation display turns fails / turns off and on throughout the drive. It turns on then goes off while backing out with the rearview camera in use. It goes off during drives, while directions are in use, while calls are in session, and with no active use at all. After checking online I found that numerous Mazda owners experience the same with thief CX5-s but there is no collective effort by Mazda to find a solution. I paid for extended warranty with Navigation Display covered and they still cannot find a solution. This is more than inconvenience. It is a serious safety issue when physical distraction is caused by manufacturer defect which can lead to accidents on the highway at high speeds relying on the navigation, while backing up viewing the camera, while driving on windy roads and the screen goes out. The auto response for most drivers is to try and reach for the phone to continue directions, stop abruptly if backing up and the screen goes out, reach for the phone to take it off blue tooth so the hands free conversation is not dropped. It is not to much to expect a major auto manufacturer to have a stable navigation screen. The local dealerships do not take it seriously. How can this matter be escalated as a matter of safety?

My Mazda has a feature called SBS (Smart Brake Support). It is touted as a safety feature, as it will brake the car when it approaches an object without driver braking. It can be disabled by the driver via the navigation panel; however, it automatically engages again upon engine start up. On a few occasions, when approaching a vehicle, I have braked and release, upon seeing the vehicle ahead begin to move. On such occasions, my Mazda's SBS activated, screeching my car to a near stop, scaring me and the vehicle behind me nearly rear-ended me. This action scared me, which affects my ability to control the situation and conduct appropriate action. I have contacted Mazda to ask for a permanent deactivation of this dangerous feature. They have been unable/unwilling to assist. They have concern that if a different driver should drive my vehicle, it would be problematic. I explained that this is my vehicle and I fear their SBS feature will cause me to be rear-ended and seriously injured. I have requested that the Mazda Customer Service rep submit a safety complaint on this issue. An Internet search finds that there are other customers with the same safety concern on Mazda's SBS feature. It is time that this be addressed.

The main screen in the middle of the vehicle experiences “ghost touches” or acts like it’s being controlled sporadically without any buttons or the screen being touched. It does it so aggressively that it causes major distraction while driving and will even change navigation routes while driving and make calls while trying to navigate. This is a huge safety issue especially for younger drivers that can’t handle this well. It makes beeping sounds and changes the screens very quickly and many times I’m unable to stop it. I’ve researched ways to fix it online with no success without spending a large amount of money at a dealership. I’ve seen many many people online with the same issue. I bought the vehicle new, and it began doing this within the first year.

Blind spot monitoring system warning appears on dashboard of vehicle after driving for about 50-60 miles. This occurs only when I drive >50-60 miles in one trip without shutting off my vehicle. Speed does not matter. My sensors will not work until I turn off my car and turn it back on. This started as soon as I purchased my vehicle in July 2020. 1 previous owner (lease) before I purchased the vehicle. No prior accidents. Got the vehicle at ~30,000 miles. In January 2021, I drifted off the freeway and hit a tree going 35 mph during a snow storm. It was only myself (driver) and a passenger in the front seat at the time of the incident. Both were wearing seatbelts. The seat belts locked up, but airbags never deployed for myself or the adult passenger in the front seat. Driver sustained no injuries, but the passenger smashed their knee into the glove compartment and smacked their head on the window/seatbelt holder on the side of the interior wall. The passenger was asleep during the incident, which may have explained why they did not brace themselves. One minute we were on the freeway, then we hit a slippery spot, and within seconds we were head on with a tree. Drove away to avoid the possibility of any vehicles following my path and smashing into us. Car was still driveable somehow. Car was repaired after 3 weeks at Caliber Collision and looked great. Sensor issue persists still, but unrelated to accident. Mentioned it to Caliber Collision when vehicle was being repaired and they had a Mazda service person come out with a sensor machine and they could not find the issue.

Mazda has termed the issue Ghost Touch in their CX-3 models, which the NTSB issued a Technical Service Bulletin. It is dangerous as the infotainment system begins to switch between functions on its own, without driver or passenger input, and while the cars is in motion; changing radio stations, dialing phone numbers, turning the system display to Night Mode making it impossible to read while using the vehicle navigation system, exiting navigation maps altogether. The part number given to me by Mazda is K123611J0C. The dealer diagnosed and confirmed this issue in April 2022. They stated it is a common problem but it is not covered under warranty. Replacement costs quoted was over $1400, plus $180 to diagnose the problem.

The Mazda SCBS (Smart City Brake Support) system malfunctioned in my vehicle. This system can inadvertently apply the brake if the system malfunction. It was told to me by the dealership that it was a known issue with the CX5s around this model year and I really think it should be a recall. Not having this safety-critical system working properly because of a manufacturer defect isn't a great thing to put on the traveling public. Not having this system could cause people to become complacent expecting the system to work properly and stop them from rear-ending another vehicle. The warning light randomly came on one day, and would also come on from time to time which the manufacturer states as "normal". I had the system inspected by Mazda and they told me "This is a common issue that we have seen frequently." I had to pay out of pocket $800 to get this safety-critical system repaired that really should be covered by the manufacturer due to a malfunction in their system.
