Touch Screen and/or infotainment center causing ghost touch. Available for inspection. Ghost touch (known Mazda issue) with touch screen has been changing radio stations, increasing volume to max. Will go into user settings and change guidance voice to full volume, increasing bass to full volume, fast forward songs, mute phone call feature, randomly switch from bluetooth to handset of phone. All of this is done without the driver or anyone else in the car touching anything. When this happens there is no easy fix. I cannot just stop the song, mute the volume. We have to wait for it to decide to stop and fix itself. It is a safety issue because You are driving and randomly volume goes to full blast an startles you, cannot hear what is going on around you, and hurts your ears. This is distracting and I have swerved my car because of it. …

This car that I financed on [redacted] 2024 has been back to the dealership over 6 times. My car loses power on the freeway and all main roads. I push the gas pedal and nothing happens so I am forced to pull over and turn the car off and restart it again. It's very dangerous when I'm merging on the freeway and I cannot accelerate and have to pull over in traffic. Sports cars International in Lynnwood Washington is well aware of the issues I've been having and they have not fixed them. They have allowed me to drive off the lot knowing I am in a car that is dangerous and unsafe, a car that could kill another family or myself. They are unresponsive to call of my phone calls and emails. This car has had nothing but problems since then day I drove it of the lot. Come to find out from their Yelp and BBB reviews thus happens to a lot of people that buy cars from them. …
I drive a 2018 Mazda CX5. My "infotainment system" which contains radio, phone, and GPS controls began making random unprompted selections while I would not touch it. This is an ongoing issue. The name for this issue is called "ghost touch" While the Mazda system "locks" the touch screen while the car is moving, the issue continues as soon as you come to a red traffic light. Without putting the car in park, the touch screen reactivates and the issue proceeds. This is a safety issue as it can cause distractions while driving such as sudden significant changes in music volume and it can call a random person if your phone is connected to Bluetooth. Regardless of if the car is moving or not, this causes a driver to take their focus away from the road. From a quick google search, this is a common issue. …
The parking break is getting stuck and we are unable to release it. We have gone to various mazda showrooms and service centers but no one have been able to find the issue. We are scared that on the highways the car can malfunction. The parking break warning sign comes on on its own even when the vehicle is moving which is a big concern for us while driving. When I searched for this issue online, I can see few articles where different models of Mazda has same issue and they recalled those vehicles. Mazda service center people after charging me for the issue, suggested not to use parking brake, even I don't use that it gets on by itself. There is a warning symbol. It is available for inspection when requested. Electronic Parking Brake Component is not working. Multiple mazda showroom people confirmed this and none of them can fix this.
On 11/28/2021, my vehicle suddenly showing five warnings 1, front camera sensor malfunction, 2, smart brake system malfunction, 3, forward smart city brake support malfunction, 4, HBC/LAS system malfunction, and 5, SCBC malfunction. I have no idea which part was go wrong, but this is not the first time my vehicle shows the same warning. Back to 12/20/2019, my vehicle has a same warning showed, I bring my vehicle to dealer to check but after they check, they told me nothing wrong. After two year the same problem come out again, I am very concern about the safety of my vehicle. The first time having a issue was my vehicle just a year old, and today the same issue come out again. Please help me to look up my vehicle is it any part has to recall and need to fix it. Thank you
Infotainment system/radio: Radio stations start changing by itself while loudly beeping constantly while I drive. I lose total control of the infotainment system. It becomes possessed. The infotainment system automatically starts moving to different screens and tries to delete stations. Very unsafe. I've seen reports of this happening on other Mazda vehicles and other models were recalled for it. Considered a "ghost touch." This was an actual recall on another Mazda model. https://static.nhtsa.gov/odi/tsbs/2019/MC-10164268-0001.pdf The problem is wider than that: Complaints from other Mazda owners: https://www.reddit.com/r/CX5/comments/mu0682/advice_on_2018_cx5_touring_multimedia_display/ https://www.bbc.com/news/technology-60333765
This vehicle has stalled out while driving at least 4-5 times since purchasing it in 2018, although issues started about 2020 or 2021. It usually starts with the radio console either malfunctioning or going dead completely while I'm driving and several minutes later (usually after stopping at a red light but sometimes while actively driving) the car stalls out in the middle of traffic. It starts up after few minutes but it's a very dangerous situation. It also sometimes hesitates when putting my foot on the gas, as if there's a fuel injection problem. I already got all the recalls fixed but there's obviously other significant problems with this vehicle. If it causes me to get injured I will be taking legal action.
While driving through town the braking system malfunctioned and the car came to a stop in the middle of the road with messages on dash saying the smart city braking support was malfunctioning as well as brake assist. Engine light came on as well as traction control light right after the car coming to a sudden hard braking stop. Drove straight to shop to check engine code which was p0882. I am so afraid of this happening on the highway with my daughter in the car. There is a recall for this system but my car isn't under the recall so I'm sure there are others that are having the issue but aren't covered under the recall either.
Infotainment system has begun exhibiting phenomenon described as "ghost touch" where options are selected randomly by the system due to touchscreen failure. This happens while the vehicle is moving and creates a significant distraction to the driver, creating a safety hazard for driver, passengers, and other cars on the road. This vehicle has not been inspected by a dealership but internet information indicates it is a known issue but a recall has not been issued from Mazda, which compromises the safety of the vehicle. No warning for incidents. This is an ongoing issue and occurs routinely during daily driving.
