2017 Mazda CX-5 Electrical System

UNKNOWN The infotainment system started malfunctioning on its own. Changes channels on radio, goes into settings and makes changes. Calls phone numbers etc. Does it more in the cold weather

I purchased this vehicle on the 10th of September. BY the 12th I I noticed the infotainment system was doing its own thing without me touching anything. The next day it did the same thing I E.changing stations on its own,volume going up or down etc...

Unknown The infotainment system started malfunctioning on its own

The infotainment system in my 2017 Mazda CX-5 exhibits dangerous behavior consistent with known defects described in the Mazda Infotainment Class Action Settlement (Case No. 8:21-cv-01355). The infotainment system and touchscreen repeatedly activate critical functions on its own (“ghost touches”), sometimes going black, changing critical settings, disengaging phone calls as well as unexpectedly activating phone calls, and navigation features engage or freeze unpredictably. These malfunctions distract from safe vehicle operation, requiring driver attention to manage the malfunctioning display. The vehicle’s display is integrated with backup camera, audio, and Bluetooth controls, so these repeated malfunctions cause safety concerns while driving. Mazda and the dealership have refused to repair the defect under the Limited Warranty Extension established in the settlement, incorrectly claiming the issue is unrelated to the CMU (connectivity master unit). However, these symptoms are identical to those described in Mazda’s internal service bulletins (CSP13 and TSB 09-022/17) and covered by the settlement. I believe Mazda is failing to properly address a continuing safety-related defect that impacts infotainment stability and driver concentration. These issues have occurred for years and are continuing nearly every time I operate the vehicle.

This car has an issue with 'ghost touches' on the infotainment screen. We had it replaced under warranty in January 2020, and the same issue is happening again. Searches online show this is a widespread problem and Mazda wants to charge $1,000 to fix it this time. It is a distraction, turns music on/off volume up/down and can cause dangerous unexpected distractions.

There is a known issue of "Ghost Touching" on the infotainment system on 2017-2020 Mazda's. The ghost touching causes the infotainment center to randomly self-select options on the screen, which is highly distracting. The following are experiences I've had while driving (sometimes going 70MPH on the interstate), where my infotainment center begins to make selections on it's own: Unpausing paused music Making random phone calls Opening text messages and selecting the reply button Flipping between screens continuously Ending phone calls This is extremely distracting and dangerous. Mazda is aware of this issue. I had my screen replaced in 2020, and replaced with another faulty screen that I now have to get replaced again.

Vehicle Infotainment Center - the touch screen will automatically select options and click options while driving, causing a distraction and most recently attempting to enable a child lock. It will do it while the car is both driving and while stopped. It will randomly do it on both the Radio Screen and the Navigation screen.

The vehicle display registers false “phantom” touches, causing it to behave erratically. Mazda issued a service bulletin for 2014-2016 Mazda 3 models but this affects most Mazda models through at least 2020 including our 2017 CX-5. Mazda has not acknowledged this for other vehicles. My 2016 Mazda 3had the repair completed under a service bulletin. Unfortunately the dealer will charge a diagnostic fee for this vehicle. Mazda does offer a repair part for this issue, where they previously required complete CMU replacement, so they know it’s a problem. This results in sudden and random changes in volume, navigation, radio, etc with no intervention, causing a significant distraction and safety concern.

My touch screen, has been acting up. While driving, the navigation system will automatically change prompts while driving. It will change to music, random dials, consistently change to random dials. I am unable to stop the dials from changing. I have read on the internet people are calling this "ghost touching". The volume will randomly go up high while driving. I am unable to control the volume or prompts. This is dangerous while on the road. I am unable to hear first responders while driving in traffic. This is a huge distraction. Many people I am reading are going through this with their Mazdas... This is costing us more than 3,000 or 4,000 to get fixed. I am unable to get this fixed for this price. I am unable to get a new car.

I have reported this same issue to NHTSA since 2021, and the issue persists to date. Other model years of Mazdas (2017, 2018) including my vehicle have been experiencing "ghost touch". This is an issue that Mazda addressed under a recall for the 2014-2016 models, however, has failed to extend. This poses as severe safety issue as the vehicle randomly increases the volume and will change settings that can either startle the driver and/or make visibility of the cluster impossible especially while driving at night. Please address this issue. There are numerous complaints with this specific year and model alone; but I am certain if searches were conducted on other models, the same issue will be found.

The infotainment system is experiencing 'ghost touch'. It random selects options such as volume, track, adjust bass/treble, etc.... It is very distracting and I don't understand why the recall for this specific issue, is only covered until 2015. This electrical short continues to happening on later models.

There is an electrical issue with the infotainment system. It changes settings/programmed setup on its own. It is a known issue that mazda owners call “ghost touch”. This is becoming a safety concern for me as it has toggled for the smart city brake support and blind spot monitoring to toggle to off randomly. Although it is not relied on by myself, it can cause an accident or death if does not engage. Additionally, it has changed my display (driver gages) to the lowest setting which is extremely difficult to see at night. As well as the head unit (infotainment system). When this happened, I could not safely read the speed I was going nor reset the display brightness. Mazda needs to take responsibility of this as all system settings are located in the infotainment system. It has apparently also been a known issue for Mazda dated back to 2013 from researching online. Thank you.

The display operates by itself. This is a known issue commonly called “ghost touch” and Mazda has issued service bulletins for 2014-2016 model year cars. Unfortunately other cars including my 2017 CX-5 are also affected. This is a safety issue as the navigation will stop working and the constant beeping from the ghost clicking is very distracting and can lead to the driver not focusing on the road. Mazda should be required to recall all affected model years, not just the 2014-2016.

The car battery does not get fully charged even after long trips and continuous use of the vehicle. It has been so ever since the vehicle was purchased brand new and maintained meticulously with all service performed on-time at the dealership. Even after long trips exceeding 350 miles, the battery would charge only up to 50% (12.2 volts) and never to 100% (12.7 volts). Thereafter it would quickly discharge to Low (<11.9 volts) if a few shorter trips were made. Upon bringing this to the dealer’s attention while the car was still under warranty, they ran a battery and alternator test and quickly dismissed the issue saying that both the battery and alternator were working fine. Nevertheless, in just two years the OEM battery failed from constantly being in a state of low charge, despite using the vehicle regularly for long trips. Because the dealer refused to honor the warranty, I had to replace with a new battery at my own cost. Now the new battery doesn’t charge beyond 50% (12.2v) either, and I have to routinely charge it every few days to full (12.7v) with an external battery charger just so the battery doesn’t die and either gets me stranded on the road (safety issue for myself and others) or damages computers/other electrical components (reliability and repair issue).

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.

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 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?

The Mazda connect touch screen in the center display doesn't always accept touch commands properly and regularly operates by itself (ghost touch) while in drive.

Connectivity Master Unit controlling the infotainment system has failed. Infotainment system continuously rebooting, freezing, change radio presets on its own and changing to home screen, and navigation starts speaking while listing to music.

KNOWN GHOSTING ISSUE CAUSED BY MANUFACTURING AND DIAGNOSED BY MAZDA. THE LIGHTS INSIDE FLICKER, THE RADIO/NAVIGATION/TELEPHONE (BLUETOOTH) STARTS, STOPS, AND MOVES AS IT WANTS TO. THIS CAUSES DISTRACTIONS AND IS UNSAFE WHILE DRIVING. THERE ARE RECALLS ON OTHER MODEL CARS FOR THIS, HOWEVER, MAZDA WON'T FIX MY CAR EVEN THOUGH THEY ACKNOWLEDGE THIS WAS A MANUFACTURING PROBLEM.
